Consequences of Integrated Use of Organic and Inorganic Fertilizers on Yield and Yield Elements of Rice
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 5
Abstract
The different concern and issues of contemporary Indian agriculture, gave birth to varied new agriculture ideas of farming like organic farming, natural farming, biodynamic agriculture, and do- nothing farming and ecological agriculture, etc. Integrated use of organic and inorganic fertilizers can improve crop productivity, and encourages soil health and fertility. As perceptive numerous publications, it is concluded that, the application of farmyard manure in combination with three levels of chemical fertilizers [80: 40: 30, 120: 60: 45 and 160: 80: 60 kg N, P2O5 and K2O ha-1, respectively], on yield and yield elements, Rice shows the subsequent information on grain and straw yield, number of tillers, panicle length, filled grains per panicle, 1000-grain weight and nutrient uptake were observed. The results showed that, application of farmyard manure at 10 t ha-1 increased grain yield of rice by 25%, compared to no farmyard manure control. Similar observations were additionally created on straw yield, tiller number, filled grains per panicle, and 1000- grain weight. There have been important interactions, between farmyard manure and inorganic fertilizer treatments. The useful effects of application of farmyard manure, were not increased at augmented rates of application of inorganic fertilizers. However, the highest grain yield of rice was obtained, with the application of farmyard manure at 10 t ha-1 and inorganic fertilizer at 120: 60: 45 kg N, P2O5 and K2O ha-1. It was ascertained that, the increased grain yield was due mainly to increased nutrient uptake and the number of tillers, filled grains per panicle and 1000-grain weight.
