Productivity and profitability of baby corn (Zea mays)-based cropping systems under various nutrient-management practices

A field experiment was conducted during 2016–17 to 2017–18 at the ICAR-Indian Agricultural Research Institute, New Delhi, study productivity and profitability of baby corn (Zea mays L.)-based cropping system under various systems with different nutrient-management levels. The laid out in a split-plot design 3 corn-based (CSs) main plots, viz. CS1 , rainy season corn-winter corn-summer (RBc – WBc SBc); CS2 RBc + vegetable fenugreek (Trigonella foenum-graecum L.) summer cowpea [Vigna unguiculata (L.) Walp.] VFg SCp); CS3 sweet SSc), 5 levels, N1 100% recommended dose nitrogen (RDN) through urea fertilizer (100% RDN F); N2, 75% F 25% FYM (75% –F FYM); N3 vermicompost VC); N4 N % leaf compost LC); N5 microbial consortium Rhizobium/Azotobacter phosphorus-solubilizing bacteria potassium-solubilizing (R/Azo PSB KSB), subplots. yield component crops converted presented terms corn-equivalent (BCEY) for better understanding. Among systems, BCEY differed from 1.99 2.18 Mg/ha season. Baby CSs intensified winter season, resulted significantly higher (2.42–2.52 Mg/ha) than sole (CS1 ). Similarly, (3.03–3.07 Mg/ ha) recorded . lowest both years. net returns all not significantly. During (130–142 × 103 `/ha) were (CS2 ) (95–98 `/ha). (~186 CSs. FYM, followed by VC
