ABSTRACT
Makhana or fox or gorgon nut (Euryale ferox Salisb.), being an important underutilized aquatic food crop, and realization as one of the value-added products, a field experiment was undertaken on improvised agro-techniques including INM (integrated nutrient management) during pre to post-monsoon period at the farmer's field at Kalinarayanpur, Nadia (West Bengal), India. Field experiment was designed in randomized block design, comprised 11 treatments with major plant nutrients, combination of organic and inorganic sources + spraying of micro nutrient including NPK [F1 - Control, F2 - 3 t FYM ha–1, F3 - Neem oilcake 2 q ha–1, F4 - 3 t FYM ha–1 + NPK (30:20:10 kg ha–1), F5 - Neem oilcake 2 q ha–1 + NPK (30:20:10 kg ha–1), F6 - 3 t FYM ha–1 + NPK (30:20:10 kg ha–1) + Zn (chelamin) spray at 20 and 40 DAT, F7 - Neem oilcake 2 q ha–1 + NPK (30:20:10 kg ha–1) + Zn (chelamin) spray at 20 and 40 DAT, F8 - 3 t FYM ha–1 + NPK (30:20:10 kg ha–1) + Zn (chelamin) spray at 20, 40 and 60 DAT, F9 - Neem oilcake 2 q ha–1 + NPK (30:20:10 kg ha–1) + Zn (chelamin) spray at 20, 40 and 60 DAT, F10 - 3 t FYM ha–1 + NPK (30:20:10 kg ha–1) + Zn (chelamin) spray at 20, 40 and 60 DAT and NPK spray at 60 DAT and, F11 - Neem oilcake 2 q ha–1 + NPK (30:20:10 kg ha–1) + Zn (chelamin) spray at 20, 40 and 60 DAT and NPK spray at 60 DAT), respectively replicated thrice. Results reveal that INM (basal as well as spraying) had a great role for boosting up crop growth, yield attributes and crop productivity. Maximum output exhibited with the treatment (F11), which combined of all essential plant nutrients in balanced form including spray (zinc) and in time, and obviously, this was significantly higher than that of other treatments. Increment in this treatment over others was to the tune of 0.08 to 67.41%, respectively. Likewise, higher profitability (` ha–1), B-C ratio (1.975 - 2.035) etc. had gone in favour of the treatments (F11 and F10), which consumed more nutrients than that of other combinations due to more production system as well as more remuneration.
