Pigeonpea was taken as base crop and baby corn as inter crop. The experiment with varied planting geometry and nutrient management practices consisted of 12 treatments was laid out in RCBD design replicated thrice. The highest plant height at last harvest was recorded with pigeonpea (60-120-60 × 30 cm) + baby corn (30 × 30 cm) intercropping (115.8 cm), Among intercropping treatments pigeonpea (60-120-60 × 30 cm) + baby corn (60 × 20 cm) where both the component crops receiving their RDF separately on population basis registered significantly higher total dry matter over other intercropping systems at all growth stages (6.13, 52.03, and 112 g plant -1) at 20,40 DAS and at harvest. The highest number of babies was counted with sole baby corn sown at 60 × 20 cm apart (7.40) closely followed by sole baby corn of spacing 45 × 20 cm (7.23). The highest grain yield of 2494 kg ha-1 pooled over years was noticed with sole pigeonpea in paired row 60-120-60 × 30 cm closely followed by 2454 and 2346 kg ha -1, It was found that pigeonpea (60-120-60×30cm) + baby corn(30×30cm) receiving respective RDF separately by components crops on population basis recorded maximum pigeonpea equivalent yield (4767kg ha-1). 2030 (Abrol et al., 2008) to feed the growing population. This additional production has to come from existing land and water resources. Pulse production in the country is not keeping pace with demand driven by population because of diminishing land holding sizes and competition for land from cereals, commercial crops and horticulture crops. Scope of extending area under pulses as pure stand is blinking. The intercropping system Introduction The greatest challenge of the 21st century in many developing countries is to produce more and more basic necessities viz., food, fodder, fuel and fiber for ever increasing human and animal population from the limited available land. Food and Agricultural Organization (FAO) estimates revealed that 50 per cent more food grains needs to be produced by 211 Int.J.Curr.Microbiol.App.Sci (2019) 8(4): 211-221 besides meeting the varied requirements of the farmers, it harnesses the farm resources efficiently. Development of feasible and economically viable systems largely depends on adoption of proper planting geometry, planting time and selection of compatible crops. Thus, objective of intercropping is now more towards augmenting the total productivity per unit area of land per unit time by growing more than one crop in the same piece of land either simultaneously or sequentially for better utilization of environmental resources (Rajat and Singh, 1979). Morphological features, long duration and elasticity nature of pigeonpea, accommodate more number of short duration crops/vegetables as addition to increase number of products / crops / per unit area in same land in a year as against taking only one crop of maize under rainfed situation which is widely being followed at present in the region. acid and low calorie vegetable with high fibre content without cholesterol. Due to its rich nutritive value fetches higher market price resulting into higher income for the growers. Further, it is also free from residual effect of pesticides as it is harvested within a week of tassel emergence and the young cob is wrapped up tightly with husk and well protected from insects and pests (Pradeep et al., 2004). The planting pattern also plays a key factor in exploiting the resources effectively. The technique of paired row planting without reduction in plant population has been developedfor effective and efficient utilization of resources by component crops. There by harness maximum yield advantage from an intercropping system (Waghmore et al., 1982). Materials and Methods Field experiments was conducted to achieve the objectives of the study entitled “Studies on fertilizer management and planting geometry in pigeonpea based bio intensive cropping system during Kharif 2016and 2017 at College of Agriculture, University of Agricultural and Horticultural Sciences (UAHS), Navile, Shivamogga. The soil of experimental field was red sandy loam in texture low in organic carbon (0.50%) and available nitrogen (232 kg ha-1), high in available phosphorus (77.40 kg ha-1) and medium in available potassium (193.50 kg ha-1). The treatments included in the experiment were T1: Sole pigeonpea (90 × 15 cm), T2: Sole pigeonpea (30 × 30 cm), T3: Sole pigeonpea (Paired row) (60-120-60 × 15 cm), T4: Sole pigeonpea (Paired row) (60120-60 × 30 cm),T5: T4 + baby corn (60 × 20 cm) (RDF separately to both the component crops based on plant population),T6: T4 + baby corn (30 × 30 cm) (RDF separately to both the component crops based on plant population),T7: T4 + baby corn (30 × 30 cm) (RDF of baby corn as per population applied Importance of baby corn is little known to the Indian farmers in spite of the fact that it fetches very lucrative price in national and international markets. Thailand and China are the world’s leading countries in baby corn production. Baby corn cultivation is now picking up in some states of India (Ramachandrappa et al., 2004). Baby corn is the young and unfertilized ear of the corn (Zea mays L.) harvested just before or soon after emergence of silk. Baby corn maize types are medium plant type and provide succulent delicious green ears within 65to 75 days after sowing. The husked young ear in canned or fresh style is more popular vegetable because of its sweetness, flavour, and crispness. It is a highly nutritious vegetable with protein (15-18 %), sugar (0.016 - 0.020 %), phosphorus (0.6 - 0.9 %), potassium (2-3 %), fibre (3-5 %), calcium (0.3-0.5 %), ascorbic acid (75-80 mg 100 g-1) as its nutrient composition. In addition, it is a rich source of thiamine, riboflavin and folic 212 Int.J.Curr.Microbiol.App.Sci (2019) 8(4): 211-221 uniformly to both the crops), T8: T4 + baby corn (60 × 20 cm) (RDF of baby corn as per population applied uniformly to both the crops), T9:T4 + baby corn (60 × 20 cm) (RDF of pigeonpea as per population applied uniformly to both the crops), T10:T4 + baby corn (30 × 30 cm) (RDF of pigeon pea as per population applied uniformly to both the crops), T11: Sole baby corn (60 × 20 cm), T12:Sole baby corn (45×20 cm). The experiment was laid out in randomized block design with three replications. plant-1. Sum of the dry matter accumulation in different plant parts was the total total dry matter g plant-1. Plant height The babies harvested from sampled five plants of all pickings were dehusked added and average dehusked baby weight was expressed in g. Number of babies harvested plant Total number of babies from all the pickings obtained from randomly selected five plants was counted and the average was considered as number of babies per plant. Weight of dehusked baby The plant height of tagged plants was measured from base of the plant to the base of the fully opened top leaf until tassel emergence. After tasseling, the plant height was measured from the base of the plant to base of the flag leaf and average of five plants was represented as plant height and expressed in cm. Dehusked to husked ratio It was calculated by using the formula given below Dehusked to husked ratio = Number of leaves The total number of green leaves produced plant-1 was counted from five randomly selected plants and the average was taken as the number of green leaves plant-1. Weight of de husked babies Weight of husked babies Grain yield The grain yield obtained from net plot after threshing winnowing, cleaning, and drying was used to estimate yield ha-1 and expressed in kg ha-1. Leaf area index Leaf area index is defined as leaf area per unit land area. It was calculated by dividing the leaf area plant-1 by the land area occupied by single plant or spacing. Pigeonpea equivalent yield (PEY) The pigeonpea equivalent yield of pigeonpea + baby corn intercropping system in experiment - I was calculated by taking into account the grain yield of pigeonpea, yield of babies and green fodder yield of baby corn and the prevailing market prices (Appendix I) Finally pigeonpea equivalent yield was calculated using the formula given below. Dry matter production and accumulation in different plant parts Three plants from each plot in gross cropped area were collected randomly at 20 and 40 DAS and at harvest separated into leaf, stem and babies and dried in hot air oven at 65 to 70oC until constant weight was obtained. Mean was worked out and expressed in g PEY = Ybc×Pbc+Ybgf×Pbgf +Ypp Ppp 213 Int.J.Curr.Microbiol.App.Sci (2019) 8(4): 211-221 Similarly, in experiment II, the pigeonpea equivalent yield was estimated by using the formula given below area index (0.91, 6.01, and 4.72) was estimated with sole baby corn planted at 45× 20 cm spacing. It was significantly superior over rest of the treatments at 20 and 40 DAS, whereas, at harvest, it was on par with sole baby corn planted at 60× 20 cm and intercropping system pigeonpea (60-120-60 × 30 cm) + baby corn (30× 30 cm) where both the component crops received their respective RDF on population basis. Year wise data almost followed the same trend as that of pooled over years. Among intercropping treatments pigeonpea (60-120-60 × 30 cm) + baby corn (30 × 30) in which both the component crops received respective RDF on population basis recorded maximum LAI of 5.43 and 4.27, respectively, at 40 and at harvest which was significantly superior over others intercropping systems except T8 at 20 DAS and at harvest. Higher LAI, with closer spacing crop is the reflection of proper exploitation of ground area. The next best was T5 pigeonpea (60-120-60× 30cm) + baby corn (60× 20) with application of RDF separately to both the component crops on population basis. Higher LAI was due higher leaf area since; it is a derivative of leaf area. This might be due to wider inter spaces between paired rows which would have helped the intercrops to grow better and making relatively less space available for growth of weeds. Further legumes make part of nitrogen available to baby corn as well. This is in corroboration with findings of Bali reddy et al., (2009) early stages of crop growth.

The highest plant height at last harvest was recorded with pigeonpea (60-12060 × 30 cm) + baby corn (30 × 30 cm) intercropping (115.8 cm) closely followed by crop geometry of pigeonpea (60-120-60 × 30 cm) + baby corn (60 × 20 cm) receiving respective RDF on population basis by component crops. More plants per unit area in these treatments was the main reason for taller plants due to competition for light and better nutrient supply. This might have also due to legume effect and less weed growth. Similarly, these findings are in line with Bali et al., (2009). Higher plant height of baby corn with crop geometry 45 × 20 cm than 60 × 20 cm was attributed to increase in interplant competition. Total dry matter of baby corn Among intercropping treatments pigeonpea (60-120-60 × 30 cm) + baby corn (60 × 20 cm) where both the component crops receiving their RDF separately on population basis registered significantly higher total dry matter over other intercropping systems at all growth stages (6.13, 52.03, and 112 g plant-1 at 20,40 DAS and at harvest, respectively, The leaves per plant recorded as influenced in crop geometry and fertilizer management in pigeonpea + baby corn intercropping system varied significantly at all stages of the crop. The pooled data showed that maximum leaf 214 Int.J.Curr.Microbiol.App.Sci (2019) 8(4): 211-221 followed by pigeonpea (60-120-60× 30 cm) + baby corn (30× 30 cm) which are on par. Intercropping treatments where in component crops received their RDF separately on population basis (T5 and T6) > RDF of baby corn uniformly to both the crops (T7 and T8) > RDF of pigeonpea uniformly (T9and T10) are in the order of merit in recording total dry matter. Total dry matter is sum of the dry accumulated in different plant parts. Higher dry matter accumulation in leaves, stem and babies were recorded with sole baby corn treatments (T11 and T12) followed by intercropping treatments T5 and T6 receiving RDF separately on population basis (Table 1). Better dry production in these treatments attributed better nutrient availability as well as other growth resources. The magnitude of dry matter can be more meaningfully interpreted in terms of photosynthetic apparatus (leaf area and leaf area index). The variation among treatments with regard to dry matter accumulation and crop growth rate was due to variation in growth parameters. The total dry matter production curve for baby corn as influenced by planting geometry and fertilizer levels with age of the crops indicate not much variation among treatments at early stages over i.e. 40 DAS. As the age advances the total dry matter production per plant was significantly lower under intercropping situations compared to sole crop treatments (T11). It was due to increase in competition from component pigeonpea for resources. There was a greater difference between sole crop of baby corn and intercropped baby corn. superior over all intercropping treatments except pigeonpea (60-120-60× 30 cm) + baby corn (30 × 30 cm) applying RDF separately to both the component crops with which the treatment sole baby corn (45 × 20 cm) was found on par (7.23). The intercropping treatments which are receiving RDF separately to both crops (T5 and T6) > RDF of baby corn uniformly to both the component crops (T7 and T8) > RDF of pigeonpea uniformly to both the crops (T9 and T10) are in the order of merit in recording number of babies per plant. The treatments recorded significantly the least number of babies per plant are T9 (5.43) and T10 (5.44). Almost same trend was noticed both in 2016 and 2017. Baby weight The pooled data on average baby weight indicates the statistically superiority of sole baby corn irrespective of crop geometry with highest mean baby weight being recorded with sole baby corn sown at 60× 20 cm (7.78 g plant-1) closely followed by baby corn of 45 × 20 cm spacing (7.34 g plant-1) which are significantly differ. Both the sole crop treatments were found significantly superior over all other intercropping treatments. Among intercropping treatments pigeonpea (60-120-60 × 30 cm) + baby corn (60× 20 cm) both the component crops receiving RDF separately. registered the highest mean baby weight of 6.91 g plant-1, which was statistically on par with those intercrop treatments receiving RDF separately to both the crops (T6) and RDF of baby corn applied uniformly to both the crops (T7 and T8). Significantly least baby weight was obtained with treatments which received RDF of pigeonpea on population basis uniformly to both the crops i.e. T9 (5.96 g plant-1) and T10 (5.84 g plant-1). In 2016 the highest baby weight per plant was obtained with the sole baby corn of spacing 45× 20 cm (7.37 g Yield parameters of baby corn Number of babies and baby weight The highest number of babies was counted with sole baby corn sown at 60 × 20 cm apart (7.40) closely followed by sole baby corn of spacing 45 × 20 cm (7.23) which are on par and both the treatments are statistically 215 Int.J.Curr.Microbiol.App.Sci (2019) 8(4): 211-221 plant-1) closely followed by sole baby corn spaced at 60 × 20 cm (7.36 g plant-1) and pigeonpea (60-120-60× 30 cm) + baby corn (60 × 20 cm) having received RDF to both the crops separately on population basis (6.77 g plant-1) which are on par. Whereas, in 2017 the results are almost in line with pooled data. In both the years the intercropping treatments which received RDF of pigeonpea uniformly by both the component crops have recorded significantly least baby weight per plant (T9 and T10).yield is a function of yield attributes, the higher values of yield parameters viz., number of babies and baby weight noticed with sole baby corn sown at 60 × 20 cm apart (7.40 and 7.78 g plant-1) closely followed by sole baby corn of spaced at 45× 20 cm (7.23 and 7.34 g plant-1) apart from differences in population, were the reasons for higher yields. The highest dehusked to husked ratio of babies harvested was found with pigeonpea + baby corn intercropping system and sole baby corn of spacing 45× 20 cm (0.287) for data pooled. This is closely followed sole baby corn spaced at 60× 20 cm (0.275) and intercropping systems pigeonpea (60-120-60 × 30 cm)+ baby corn (30 × 30 cm) receiving RDF separately to both the component crops (0.270). closely followed by sole baby corn of spaced at 45× 20 cm (7.23 and 7.34 g plant-1) apart from differences in population, were the reasons for higher yields under sole crop situation. A strong or positive correlation between baby yield ha-1 and number of babies per plant-1 (0.942) and mean baby weight per cob-1 (0.952) was noticed (Table 2). Higher yield with 45 × 20 cm was mainly attributed for higher plant density which seems optimum. The treatments in which component crops receiving RDF separately >RDF baby corn uniformly to both the crops > RDF of pigeonpea uniformly to both the crops are in the order of merit with respect to baby yield. The variation in yield of baby corn among intercropping treatments was attributed to variation in population and different nutrient management practices (higher nutrients applied and their availability), which influenced greatly the yield components. Higher nutrient availability in treatments T5 and T6 attributed higher applied nutrients and improved microbial population (AppendixIX) over other intercropping systems (Bacteria; 256.67 and 272.67, fungi; 170 and 174.17 and actinomycetes; 29.50 and 28.17 cfu g-1 of soil, respectively). The pooled data indicate the statistical superiority of sole baby corn in yielding green fodder (45 × 20cm) over all intercropping treatments as it recorded the highest green fodder yield of 21,088 kg ha-1. This was on par with sole baby corn sown at 60 × 20 cm (19,770 kg ha-1) which is obvious. Baby yield biological yield and green fodder yield The mean baby yield obtained by treatment groups as influenced by cropping geometry and fertilizers levels is in the order of merit sole crop (T11 and T12) >intercrop treatments receiving RDF separately to both the components crops (T5 and T6) > RDF of baby corn uniformly to both the crops (T7 and T8) > RDF of pigeonpea (T9 and T10) uniformly to both the component crops. Since, yield is a function of yield attributes, the higher values of yield parameters viz., number of babies and baby weight noticed with sole baby corn sown at 60 × 20 cm apart (7.40 and 7.78 g plant-1) Among intercropping treatments, pigeonpea (60-120-60 × 30cm) + baby corn (30 × 30 cm) receiving RDF separately to both the component crops resulted in significantly higher green fodder yield of 18,945 kg ha-1 over other intercropping treatments. The crop geometry did not influence the green fodder yield. However, the treatment receiving RDF separately to both crops (T5 and T6) > RDF of 216 Int.J.Curr.Microbiol.App.Sci (2019) 8(4): 211-221 baby corn uniformly to both the crops (T7 and T8) > RDF of pigeonpea uniformly to both the crops are in the order of merit statistically. Higher green fodder yield was attributed to plant population (spacing), higher nutrient availability and better exploitation of other production factors with treatments viz., T6 and T5. Further, it is also due higher baby yield as husk also included while estimating the green fodder yield as 3/4th of dehusked baby is constituted by husk. (0.287) for data pooled. This is closely followed sole baby corn spaced at 60× 20 cm (0.275) and intercropping systems pigeonpea (60-120-60 × 30 cm)+ baby corn (30 × 30 cm) receiving RDF separately to both the component crops (0.270). Higher biological, baby and green fodder yields were positively correlated with yield components in turn yield and yield components are decided by growth parameters. Therefore crop yield depends on the accumulation of photo assimilates during the growing period and the way they are partitioned between desired storage organs of plant and vegetative parts. The sole baby corn irrespective of spacing excelled statistically over all intercropping treatments by recording the highest harvest index of 17.2 and 17.0 per cent with 45× 20 and 60 × 20 cm, respectively (Table 3). While, no significant differences were found among intercropping treatments with respect to harvest index. However, the intercropping systems in which component crops receiving RDF separately (T5 and T6) found relatively higher. Thus, higher yield and yield components may be attributed to better crop growth rate, dry matter accumulation and translocation of photosynthates from source to sink. Maximum biological yield of baby corn was realized with sole baby corn spaced at 45×20cm (8724 kg ha-1) which was significantly higher overall intercropping treatments except sole baby corn (8075 kg ha-1) sown at 60 × 20 cm for data pooled over years as the reason known. Among intercropping treatments, significantly higher biological yield of 16,315 kg ha-1 over rest of the intercropping treatments was obtained with pigeonpea (60-120-60 × 30cm) + baby corn (30×30 cm). Higher population, higher baby yield and dry biomass are caused for higher biological yield of baby corn at higher plant population. The intercropping treatments wherein, component crops receiving their RDF separately (T5 and T6) and RDF of baby corn uniformly to both the crops (T7 and T8) are statistically on par. Significantly least biological yield of baby corn was recorded with intercropping systems in which RDF of pigeon was applied uniformly both components i.e. T9 and T10 (Table 3). This is due less nutrient availability as the recommended quantity of nutrients to pigeonpea is very less (25:50:25 kg ha-1) whereas the component baby corn requires almost 6-7 times of nitrogen of that pigeonpea. The highest dehusked to husked ratio of babies harvested was found with pigeonpea + baby corn intercropping system and sole baby corn of spacing 45× 20 cm Pigeonpea yield The highest grain yield of 2494 kg ha-1 pooled over years was noticed with sole pigeonpea in paired row 60-120-60 × 30 cm closely followed by 2454 and 2346 kg ha-1, respectively, realized under the intercropping systems pigeonpea (60-120-60 × 30 cm) + baby corn (60 × 20 cm) and pigeonpea (60120-60 × 30 cm) + baby corn (30 × 30 cm) wherein, the component crops received their respective RDF separately on population basis were found on par to each other. 217 Int.J.Curr.Microbiol.App.Sci (2019) 8(4): 211-221 Table.1 Plant height (cm), number of leaves, and leaf area index of baby corn as influenced by planting geometry and fertilizer levels in pigeonpea + baby corn inter cropping system Treatments At harvest 2016 2017 P - T1- Sole Pigeonpea (90 cm ×15cm) At harvest 2016 2017 P - LAI at 40 DAS 2016 2017 P - At harvest 2016 2017 P - T2-Sole Pigeonpea (30 × 30 cm) - - - - - - - - - - - - T3 -Sole Pigeonpea (PR: 60-120-60 × 15 cm) - - - - - - - - - - - - T4 -Sole Pigeonpea (PR:60-120-60 × 30 cm) - - - - - - - - - - - - T5 - T4 + Baby corn (60 × 20 cm) (RDF separately to both the component crops based on plant population) T6 - T4 + Baby corn (30 × 30 cm) (RDF separately to both the component crops based on plant population) T7-T4 + Baby corn (60 × 20 cm) (RDF of baby corn applied uniformly to both the crops) T8- T4 + Baby corn (30 × 30 cm) (RDF of baby corn applied uniformly to both the crops) T9-T4 + Baby corn (60 × 20 cm) (RDF of pigeonpea applied uniformly to both the crops) T10-T4 + Baby corn (30 × 30 cm) (RDF of pigeonpea applied uniformly to both the crops) T11 - Sole baby corn (60 ×20 cm) T12-Sole baby corn (45 × 20 cm) S.
