tailieunhanh - Effect of integrated nutrient management (INM) on physico-chemical properties of soil, available content and nutrient uptake by okra (Abelmoschus esculentus)

The present investigation was conducted at Research Farm, Rama University, Kanpur in 2018. Total 11 treatments, each replicated thrice in RBD. Soil fertility status after the crop harvested revealed that the available nitrogen is maximum in T4 ( kg ha-1 ) and minimum in T11 ( kg ha-1 ). Available phosphorus is maximum ( kg ha-1 ) in T4 and minimum ( kg ha-1 ) in T11. Whereas available potassium is maximum ( kg ha-1 ) in T4 and minimum ( kg ha-1 ) in T11 treatment. The use of inorganic fertilizers and organic manures or micronutrients was found significant ranged between to percent. The higher P2O5 content () was observed in treatment T4 which was at par with the treatments T2 (), T3 () and T1 () where as the lower phosphorus content () was observed in treatment T11. The maximum K2O content was found in treatment T4 (), during the crop study period. The minimum K2O content was found in treatment T11 (). The nitrogen uptake was significantly highest ( t/ha) in the treatment T4 over all other treatments. The least uptake of nitrogen was found in the treatment T11 ( t/ha). Phosphorus (P2O5) uptake in course of investigation, the higher P2O5 uptake in pod was kg/ha (T4) and minimum uptake in pod was kg/ha in T11. K uptake in pods was (T4) and lowest uptake in pods was kg/ha in T11. | Effect of integrated nutrient management (INM) on physico-chemical properties of soil, available content and nutrient uptake by okra (Abelmoschus esculentus)
