Response of Different Levels of NPK and FYM on Growth and Yield of Cluster Bean (Cyamopsis tetragonoloba L.) var. Neelam-61

Today, with the advancement of environment pollution and health that is obtained from the improper use of inorganic fertilizer, production and use of organic fertilizer is considered as an important approach in the field of soil science in the world’s interest to investors. A research was conducted during Zaid season 2022 on central research farm of department of soil science and agricultural chemistry, (NAI) SHUATS, Prayagraj. Field trial was designed on Randomized Block Design with three replications and nine treatments. It may be concluded from the trial that the different level of NPK and FYM in the experiment gave the highest value. The best results were obtained with T9 treatment which included (N20P40K40 kg ha-1 + FYM10 t ha-1). This treatment resulted in the maximum plants height with the most leaves, no. of clusters plant-1, no. of pod cluster-1, no of pod plant-1, length of pod (cm) and highest pod yield. In contrast, the control treatment (T1) had the lowest results in all categories. The available NPK and FYM with the treatment combination of T9 (N20P40K40 kg ha-1 + FYM10 t ha-1) was found to be the best for the improvement of growth and yield of cluster bean. Therefore, farmers of Prayagraj region can adopt this combination to give the highest yield of cluster bean.
