INTEGRATED USE OF ORGANIC MANURE, CHEMICAL & BIO FERTILIZERS ON RICE

The present study conducted entitled, “Effect of Integrated use Organic manure and Biofertilizers on crop productivity under Rice (Oryza sativa L.) crop". Involved field experimentation conducted during Kharif season of year 2016-17 followed by laboratory analysis of the plant and soil samples in the department of agriculture chemistry and soil science, Udai Pratap Autonomous college, Varanasi (U. P). All grasses were removed from the experimental plots and soil samples have been taken from each replication plots at 30 DAT, 60 DAT and at harvesting. The experiment was conducted under randomized block design (RBD) with six treatment combinations. Treatments were replicated thrice making the total number of 18 plots. The effect of various treatments on dry matter production could be arranged in order of T6>T3>T5>T4>T2>T1 and the value were 70.25, 62.15, 59.45, 43.40, 41.25 and 35.59 gm-1 row length, respectively. Application of fertilizers alone or in combination with FYM increased grain and straw yield of rice significantly over control.
