Integrated Effect of Deeply Placed Urea and Gliricidia Green Manure on Grain Yield of Transplanted Rice

We studied the integrated effect of organic and inorganic sources of N on grain yield of rice variety PLG-1 (130 d duration) during 1991-93 wet seasons. We compared how deeply placing urea behind the plow and applying Gliricidia sepium leaves as a green manure—individually and in combination—affected rainfed transplanted rice.
