Abstract


Integrated plant nutrient management (IPNM) is the efficient consumption of nutrients by utilizing organic and inorganic sources to avoid soil degradation. The application of farm yard manure along with inorganic fertilizers is useful approach for sustainable agriculture. A pot experiment was conducted for the evaluation of integrated use of inorganic phosphorus and farm yard manure for improving growth of maize (Zea mays L.) under desert climate of Bahawalpur, Pakistan. The experiment was laid out in Complete Randomized Design (CRD) with four replications. The treatments comprised of synthetic and organic fertilizers, alone and in combination, i.e. T1; control, T2; 100% of recommended P from DAP, T3; 100% of recommended P from FYM, T4; 50% of recommended P from DAP + 50% of recommended P from FYM, T5¬; 50% of recommended P from DAP, and T6; 50% of recommended P from FYM. The results showed that treatment T4 which include 50% of recommended P from DAP + 50% of recommended P from FYM improved most of the growth parameters (shoot length, root length, shoot fresh weight, shoot dry weight, root fresh weight, root dry weight and number of leaves per plant) and relative water contents of maize plant in pot experiment as compared to control and other treatments as well. This treatment was also showed enhanced P concentration in root and shoot of maize.
