| Weed management is a primary concern in direct seeded rice (DSR) cropping because weed growth becomes a major constraint on crop yield. A two year field study was set up to evaluate the effect of various weed control measures on crop growth, grain yield and grain quality of DSR. The experiment involved five different weed control measures: hand weeding, hoeing, inter-row tine cultivation, inter-row spike hoeing and herbicide treatment (Nominee 100 SC). The extent of weed control (compared to a non-weeded control) ranged from 50-95%. The highest crop yield was obtained using hand weeding. Hand weeding, tine cultivation and herbicide treatment raised the number of fertile rice tillers formed per unit area and the thousand grain weight. Tine cultivation... |

| Comparison of soil preparation methods for direct-seeded rice in Tung Samrit area was conducted in order to evaluate the effectiveness of suitable dry direct seeding technique. The experiment was carried out in farmer’ fields in wet season 2012 using an RCB design with 4 replicates. Five treatments were tested consisting of 1) 2 ploughs, sowing and raking, 2) 1 plough, sowing and covering dry soil using a rotary, 3) 1 plough, sowing and covering moist soil using a rotary, 4) 2 ploughs, sowing and covering dry soil using a rotary, and 5) 2 ploughs, sowing and covering moist soil using a rotary. The results showed that the treatment 1 gave the highest plant density of 374 plants/sq.m. Both treatment 4 and 5 gave highest plant height of 142 – 144 cm. However,... |
