dc.description.abstractA field experiment was conducted during rabi 2020-21 at experimental farm of Tirhut college of Agriculture, Dholi (Dr. RPCAU Pusa, Bihar). The title of the research was “Studies on Enhancing Nutritional Security through Maize-Pulse based Intercropping System and Natural Resource Management”. This experiment was conducted from 2018-19 to 2020-21. The experiment was carried out in split-split plot design with three replications. The main plot consisted three methods of irrigation viz., surface irrigation, drip irrigation and furrow irrigation. The sub-plot consisted three nutrient management viz., recommended dose of fertilizer (150:75:50 kg ha-1), site-specific nutrient management (120:78:166 kg ha-1) and soil test crop response (216:140:99 kg ha-1). The sub-sub plot consisted three intercropping system viz., lentil, rajmash and vegetable pea which replicated thrice. The result revealed that growth parameters of maize like gemination percentage, plant height, dry matter accumulation, crop growth rate and leaf are index was significantly higher under drip irrigation as compared to furrow and surface irrigation. Among the nutrient management, also these growth attributes significantly higher under soil test crop response (STCR) over recommended dose of fertilizer (RDF) and site-specific nutrient management (SSNM). Similarly, under intercropping system these growth attributes also maximum in vegetable pea treatment over lentil and rajmash intercropping system. The highest yield attributes viz., length of cob (17.23 cm), girth of cob (13.94 cm), no. of cobs per plant (1.14), no. of rows per cob (15.02), no. of grains per cob (29.13) and test weight (237.08 g) were recorded under drip irrigation as compared to furrow and surface irrigation. Among the nutrient management, all these yield attributes maximum under soil test crop response (STCR). Similarly, under intercropping system also all these yield attributes higher in vegetable pea treatment over lentil and rajmash intercrop treatments. Among the different irrigation methods, significantly highest grain yield (94.24 q ha-1) was recorded under drip irrigation which was 9.49 % and 18.84 % higher than furrow and surface irrigation respectively. In case of nutrient management, significantly maximum grain yield (92.38 q ha-1) was recorded under soil test crop response (STCR) which was 9.42 % and 12.32 % higher over recommended dose of fertilizer (RDF) and site-specific nutrient management (SSNM) respectively. Similarly, in various intercropping system, significantly highest grain yield (91.23 q ha-1) was obtained under treatment vegetable pea which was 5.50 % and 12.14 % higher as compared to lentil and rajmash intercrop treatment respectively. The interaction of different irrigation methods and nitrogen management, highest grain yield was recorded under drip x STCR (96.01 q ha-1) treatment as compared to others. The N, P, K uptake in grain under drip irrigation was 132.57 kg N, 37.18 kg P and 63.19 kg K ha-1 respectively. In furrow irrigation 112.12 kg N, 31.67 kg P and 53.84 kg K ha-1 respectively. Similarly, in surface irrigation 96.02 kg N, 29.30 kg P and 49.34 kg K ha-1 respectively. The maximum protein content (8.76 %) in grain was found under drip irrigation over others treatments. In pulses (Lentil, Rajmash and Vegetable Pea), all the growth parameters were significantly highest recorded under drip irrigation followed by furrow and surface irrigation. Among the nutrient management, all the growth parameters were highest under recommended dose of fertilizer (RDF) as compared to site-specific nutrient management (SSNM) and soil test crop response (STCR). The yield attributes of pulses (Lentil, Rajmash and Vegetable Pea), viz., no. of pods per plant, no. of grains per pod and test weight were significantly higher under drip irrigation as compared to furrow and surface irrigation. Similarly, among the nutrient management all these yield attributes were recorded highest under recommended dose of fertilizer (RDF) as compared to site-specific nutrient management (SSNM) and soil test crop response (STCR). The grain yield of pulses (Lentil, Rajmash and Vegetable Pea), were significantly higher under drip irrigation as compared to furrow and surface irrigation. Similarly, among the nutrient management, the grain yield was recorded highest under recommended dose of fertilizer (RDF) as compared to site-specific nutrient management (SSNM) and soil test crop response (STCR). The maize equivalent yield (MEY) was significantly highest recorded under drip irrigation (116.72 q ha-1) which was 11.16 % and 20.11 % higher over furrow and surface irrigation respectively. Among the nutrient management, significantly maximum maize equivalent yield (MEY) was obtained under soil test crop response (111.53 q ha-1) as compared to RDF and SSNM. Similarly, among the intercropping system the highest MEY was recorded under treatment vegetable pea (118.65 q ha-1) which was significantly superior over lentil and rajmash. The gross returns (215942 ₹ ha-1), net returns (146679 ₹ ha-1) and benefit cost ratio (2.11) from maize-based pulse intercropping obtained significantly higher under drip irrigation as compared to furrow and surface irrigation. Among the nutrient management, the gross returns (206343 ₹ ha-1), net returns (134893 ₹ ha-1) significantly higher recorded under soil test crop response (STCR) over both the treatment RDF and SSNM. However, highest benefit cost ratio (1.94) was obtained under RDF. Among the various intercropping system, the maximum gross returns (219509 ₹ ha-1), net returns (147954 ₹ ha-1) and benefit cost ratio (2.06) was found under vegetable pea as compared to lentil and rajmash intercropping system.en_US
