Three Row Wet Land Paddy Weeder - Datasheet

Rice can grow well in standing water; but it does not require standing water as a rule. In the traditional cultivation water level of 2-3 inches is always maintained. This is because of the farmers belief that rice requires more water for better growth and good yields. The other reason is not to allow emergence of weeds. But in SRI, the field is irrigated just enough to saturate the soil with moisture. Subsequent irrigation is suggested after soil forming fine cracks. The irrigation interval depends on the soil type and weather condition. This kind of water management avoids root degeneration in rice plant, increases microbial activity in the soil making the nutrients easily available to plants. It helps in healthy and better growth of roots. The roots also spread wider. However, due to intermittent wetting and drying allows the weeds to grow more rapidly and abundantly.
