Effect of NP fertilization and stress-mitigating chemicals on productivity and profitability of summer cowpea (Vigna unguiculata) intensified with baby corn (Zea mays)

A field study was carried out during the summer seasons of 2019 and 2020 at research farm Agriculture University, Kota, Rajasthan, to effect NP fertilization stress mitigating chemicals on productivity profitability cowpea (Vigna unguiculata L.) baby corn (Zea mays intercropping system. The experiment conducted in a split-split plot design with 5 systems [sole cowpea, sole corn, + (2: 1), (3: 1) (4: 1)] main plot; 3 fertility levels (100, 125 150% RDF) sub-plot 2 stress-mitigating (0.5% CaCl2 1.0% KNO3 flowering pod development stage cowpea) sub-subplot, replicated 4 times. Intercropping 2:1 row ratio significantly increased equivalent-yield, monetary advantage index, land equivalent economics system while yield higher under their crops. In sub-plots cowpea-equivalent yield, land-equivalent ratio, profitability, seed cob were level over lower levels. Our results further indicated that 0.5% enhanced index 1% KNO3. Cowpea should be intercropped as RDF foliar application @0.5% is recommended achieve profitability.
