Abstract

Rice is the most important food crop for the world population, and in Tamil Nadu, rice production is significant but productivity is low compared to the world average. The major constraints in rice production are lack of integrated management practices involving land, water, crop, and inputs. In this study, an experiment was conducted at the Tamil Nadu Rice Research Institute in Aduthurai to find a suitable method of water management and cultural practices to increase rice productivity. Three water management practices (continuous submergence, cyclic submergence, and saturation throughout crop growth) and four cultural practices (transplanting + herbicide weed control + recommended fertilizer dose, direct sowing of sprouted seeds + herbicide weed control + 1 spot weeding + recommended fertilizer dose, direct sowing of sprouted seeds + herbicide weed control + 1 conoweeding + recommended fertilizer dose, and direct sowing of sprouted seeds on the second day + herbicide weed control + 1 conoweeding + recommended fertilizer dose) were tested using a short-duration rice variety (ADT 43) as the test crop.
