Abstract:

In Periyar Vaigai Command (PVC) of wetland area of Madurai Dist., Tamil Nadu, rice is cultivated as major crop, which accounts for 58.8 thousand ha. However, due to major constraint of sandy clay loam type of soil of this area reduce the productivity of rice. This may be attributed to loss of applied nutrients caused by leaching of water in the above soil having more sand in proportion besides continuous use of synthetic fertilizers that deteriorate soil physico- chemical and biological properties of the soil. Apart from the above constraints, inadequate and delayed water supply are also lead to poor growth and development and yield reduction in rice in most of the years. Under that situation, developing strategy with necessary agronomic measures is a must. Taken into account of the same, a field experiment was conducted at Agricultural College and Research Institute, Madurai during rabi season (2019-2020) in sandy clay loam soil to investigate the effect of IFS resources based nutrient management practices on rice under low land puddling condition. The experiment has eight treatments comprised of different organic amendments and inorganic fertilizers laid out in randomized block design with three replications. The results of the experiment revealed that, application of Tank silt @ 20 t ha-1 + IFS fish pond silt @ 5 t ha-1 + NPK fertilizer on nutrient balance basis (T7) recorded the highest plant height (95.1 cm) and dry matter production (22483 kg ha-1) and it was on par with application of Tank silt @ 20 t ha-1 + NPK fertilizer on nutrient balance basis (T5). Application of Tank silt @ 20 t ha-1 + IFS fish pond silt @ 5 t ha-1 + NPK fertilizer on nutrient balance basis (T7) has also significantly influenced the yield parameters of rice such as productive tillers m-2, number of grains panicle-1, number of filled & ill-filled grains panicle-1, panicle length, panicle weight, grain yield and straw yield. The highest grain yield (6803 kg ha-1) and straw yield (8497 kg ha-1) were recorded in the treatment Tank silt @ 20 t ha-1 + IFS Fish pond silt @ 5 t ha-1 + NPK fertilizer on nutrient balance basis (T7). With regard to economics, the cost of cultivation of Rs.51280 ha-1, gross return of Rs.147950 ha-1, net return of Rs.96670 ha-1 and B:C ratio of 2.89 were found to be higher in the treatment Tank silt @ 20 t ha-1 + IFS Fish pond silt @ 5 t ha-1 + NPK fertilizer on nutrient balance basis (T7). It could be concluded that application of Tank silt @ 20 t ha-1 + IFS Fish pond silt @ 5 t ha-1 + NPK fertilizer on nutrient balance basis is the best practice to improve soil fertility status and soil moisture retention required to increase growth, yield and yield attributes and economic return besides increased productivity of rice in Periyar Vaigai Command area.
