Productivity and soil nutrient balance influenced by INM under grain amaranth (Amaranthus hypochondriacus)-cowpea (Vigna unguiculata) sequence
Two-year field experiment was conducted during rabi and summer 2016–17 and 2017–18 to develop a balanced nutrient supply for grain amaranth (Amaranthus hypochondriacus L.) and cowpea [Vigna unguiculata (L.) Walp] cropping sequence. The system was assessed on the basis of GAEY, production efficiency...

Two-year field experiment was conducted during rabi and summer 2016–17 and 2017–18 to develop a balanced nutrient supply for grain amaranth (Amaranthus hypochondriacus L.) and cowpea [Vigna unguiculata (L.) Walp] cropping sequence. The system was assessed on the basis of GAEY, production efficiency, monetary returns, nutrient uptake and balance of cropping system. Application of RDN75 CF + RDN25 BC (T3) to rabi grain amaranth and RDF100 to cowpea found most beneficial compared to rest of the treatments. The superiority of T3 to grain amaranth was highlighted by the significantly higher productivity (2.60 tonnes GAEY/ha), production efficiency (14.19 kg/ha/ day), net returns (`142.1 ×103/ha) and B:C ratio of 3.24, followed by treatments T1 (RDN100 CF) and T2 (RDN75 CF + RDN25 FYM). Whereas, lowest negative balance of N and K2O and highest positive balance of P2O5 were noted
with the application of RDN50 FYM + RDN50 BC (T6) to grain amaranth. Conspicuous improvement in terms of maximum system productivity (2.46 tonnes GAEY/ha), production efficiency (13.46 kg/ha/day), net returns (`127.4 × 103/ha) and B:C ratio of 2.64 and maximum nutrient uptake by cowpea crop, lowest negative balance of N, highest positive balance of P2O5 and highest negative balance of K2O was recorded with the application of RDF100 (F4) directly applied to cowpea over other treatments
