ABSTRACT
A field experiment was conducted in the farmers' field at Kalinarayanpur, Nadia, India to visualize the effect of integrated nutrient management and integration of makhana (Euryale ferox Salisb.) - cum - fish culture on enhancing productivity and economic stability of farming community under wetland ecosystem during two consecutive period of pre- to post-monsoon season under new alluvial zone of West Bengal. The experiment was laid out in a split plot design having four levels of integrated nutrient management (N1 - Control; N2 - 3 t FYM + 1 t neem oilcake ha-1; N3 - 3 t FYM + 1 t neem oilcake ha-1 + N : P2O5 : K2O @ 20 : 30 : 20 kg ha-1 + spraying of Zn (Chelamin) at 20, 40 and 60 DAT of makhana and N4 - 3 t FYM + 1 t neem oilcake + N : P2O5 : K2O @ 20 : 30 : 20 kg ha-1 + spraying of Zn (Chelamin) at 20, 40 and 60 DAT of makhana + fish-feed) as main plot and five levels of farming systems (F1 - Sole makhana; F2 - Sole live-fishes and F3 - Sole carp fishes @ 6,000 fingerlings ha-1; F4 - Makhana + live-fishes and F5 - Makhana + carp fishes @ 4,500 fingerlings ha-1) as sub-plot treatments with four replications. From the results it reveals that production of makhana, fish yield (live & carp) as well as total MEY of the system (t ha-1) was greatly influenced due to both INM and farming system practiced in the zone. Higher results (2.187, 0.496, 1.003 and 2.537 t ha-1) were obtained with the application of 3 t FYM + 1 t neem oilcake ha-1 + N : P2O5 : K2O @ 20 : 30 : 20 kg ha-1 + spraying of Zn (Chelamin) at 20, 40 and 60 DAT of makhana + fish-feed treatment (N4). Among the different farming systems, although maximum value of seed yield of makhana (2.269 t ha-1) exhibited with sole crop (F1), but maximum combined value (3.515 t ha-1) was exhibited with the combination of N4 x F4 system. Economic analysis of makhana-cum-fish farming system revealed that maximum gross return, net return and benefit-cost ratio (1.81) had gone in favour of this combination also. Therefore, considering performance and economics it concluded that integration of makhana + live-fishes along with balance application of organic and inorganic sources of nutrients including supply of regulated fish-feed is beneficial in enhancing productivity as well as economical sustainability of the farming community.
