A field experiment was conducted at Agricultural Research Farm of Amar Singh (P.G.) College, Lakhaoti, Bulandshahar to know response of IPNS on yield, nutrient content and uptake by maize crop. The grain yield (average of two year) ranged from 33.13 to 52.56 q ha-1, strover yield 40.32 to 60.76 q ha-1 and total biological yield 73.44 to 113.32 q ha-1 where maximum yield of maize was produced by application of nutrients through 10 tonnes ha-1 FYM + Rest through chemical fertilizers (T3). Nutrient contents under integrated plant nutrient supply (IPNS) of maize crop was observed maximum 1.51, 0.45 and 0.59 percent NPK respectively, in grain and 0.98, 0.705 and 1.80 percent NPK respectively, in stover through application of nutrients by 10 tonnes ha-1 FYM + Rest through chemical fertilizers (T3). Similarly, in case of nutrients uptake by maize crop was found maximum 79.37, 23.66 and 30.74 kg ha-1 NPK respectively through grains while 59.24, 42.83 and 109.37 kg ha-1 NPK respectively, through stover of maize crop under treatment T3 (10 tonnes ha-1 FYM + Rest through chemical fertilizers). In these parameters, significant increase was recorded in the treatments received organic, inorganic and bio-fertilizer sources of nutrients in combined form.
