Effect of Inorganic Fertilizers, FYM and Nano Urea on Soil Health, Growth and Yield of Cluster Bean (Cyamopsis tetragonoloba L.) cv. HGS 563

An experiment was conducted to study the “effect of different level of N P K, FYM and Nano urea on soil health, growth and yield of cluster bean (Cyamopsis tetragonoloba L.) cv. HGS 563” at research farm of Soil Science and Agricultural Chemistry. The experiment design laid out in randomized block design (RBD) with three replications. Cluster bean was taken for study with recommended doses of fertilizers (N, P2O5 and K2O @ 20, 40 and 20 kg ha-1) was applied with organic manure (FYM). The variety of cluster bean is HGS 563 was taken for research trial. Bulk density (Mg m-3) and particle density was maximum in T1 - [NPK @ 0% + NU @ 0% + FYM @ 0%] and soil pore space, water holding capacity, pH, EC, organic carbon, nitrogen, phosphorus and potassium were recorded maximum in T9 - [NPK @ 100% + NU @ 100% + FYM @ 100%] respectively. In treatment T9 the highest pod yield of Cluster bean 55.12 q ha-1 was obtained with C:B ratio of 1:2.48. Excessive nitrogen leaching can deplete the available nitrogen in the soil, leading to inadequate nutrient levels for crops. This can result in reduced crop productivity, stunted growth, and lower yields. To solve this problem of farmers that are facing leaching of Nitrogen due to direct apply of inorganic fertilizers in granule form for that use of Nano Urea can help in reducing leaching and get maximum yield. Use of different level of Nano Urea on crop and analyzing the effect of nano urea on soil physical as well as chemical properties of soil.
