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 fertilizers on growth performance rice. experiment was conducted at two locations: Tinh Bien Tri Ton AnGiang province with varieties landrace rice AG3 AG4. Each has seven treatment. Treatments included a combination nutrients sevenrates (F1:80-40-40+ manures 10 t ha-1;F2:60-40-40+ ha-1;F3: 40+40+40+ ha-1;F4: 20-40-40+ ha-1. F5:only 12 ha-1; F6: control no dose NPK;F7: farmers used: 120-40-60+ ha-1). is arranged farmer's field, split-plot in randomized complete block design three replications. produced significant results for plant height. Panicle length grain yield but thousands grains weight not significant. Result showed that application half recommended 60-40-40 + ha-1 significantly higher value good quality lance
