Effect of use Organic Fertilizer on Yield component yield and quality of Hatri 10, Hatri 475 rice on Chau Phu a Giang, Vietnam

The present study aimed to determine the effect of different organic and inorganic source of fertilizers on growth and performance of rice. The experiment was conducted at locations: Chau Phu A Giang province with two varieties of improved rice with HATRI 10 and HATRI 475. Each experiment has seven treatments. Treatments included a combination of organic and inorganic nutrients at seven rates (F1: 80-40-40+ organic manures 10 t ha-1; F2: 60-40-40+ organic manures 10 t ha-1; F3: 40+40+40+ organic manures 10 t ha-1; F4: 20-40-40+ organic manures 10 t ha-1. F5: only organic manures 12 t ha-1; F6: control no dose of NPK; F7: farmers used: 120-40-60+ organic manures 12 t ha-1). The experiment is arranged on the farmer's field, a split-plot in a randomized complete block design with three replications. Treatments produced significant results for plant height. Panicle length and grain yield but thousands of grains weight was not significant. Result showed that application of half of recommended 60-40-40 + organic manures 10 t ha-1 produced significantly higher value for grain yield and good for quality improve variety.
