Abstract:

Soil fertility can be increased by the combination of organic and inorganic fertilizers, which improves the plant growth and development by increasing the availability of nutrients. A pot experiment was conducted to evaluate the efficacy of humic acid, phosphoric acid and compost. Experiment was laid onthecompletely randomized design having four replications with four treatments including T1-control (NPK), T2 (humic acid @ 62 kg/ha with recommended NP), T3(Phosphoric acid equailent to 90 kg/ha phosphorous with recommended NK), T4 (compost@ 10 ton/ha with recommended NPK). Wheat parameters regarding growth and yieldat maturity stage including plant height, no of tillers, no of spikelets, shoot dry weight, root dry weight, 100 grain weight, grain yield, biological yieldand N, P and K contents in straw and grain were recorded and analyzed statistically. The results showed significant differences among the treatments. The plant growth parameters increased with the application of phosphoric acid along with recommended nitrogen and potassium and showed 6.2% to 9.7% increase significantly over control. Wheat grows better and responded positively by the application of phosphoric acid with recommended nitrogen and potassium due to more root development. Root dry weight was 9.3% more as compare to control. Phosphoric acid as an efficient alternative to commercial P fertilizers and its fertigation atfirst irrigation is an appropriate time of application. The results further concluded that phosphoric acid provide better returns in terms of yield, value cost ratio and phosphorus use efficiency which were 14.3%,11.1% and 9% respectively. While potassium, nitrogen and organic matter contents were maximum where humic acid and compost were applied.
