Integrated of Organic Manures and Inorganic Fertilizers was Effecive for Yield, Component Yield and Quality of Landrace Rice on An 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 two locations: Tinh Bien and Tri Ton AnGiang province with two varieties of landrace rice with AG3 and AG4. Each experiment has seven treatment. Treatments included a combination of organic and inorganic nutrients at sevenrates (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 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 lance rice.
