Effect of Organic, Inorganic and Biofertilizers on Growth, Yield and Quality of Cluster Bean (Cyamopsis tetragonaloba L.)

Cluster bean (Cyamopsis tetragonaloba L. Taub) popularly known as "Guar" is an important legume crop mainly grown under rainſed conditions in arid and semi-regions of Rajasthan during kharif season. The main objective is to optimize the concentration of NPK, FYM, Vermicompost, PSB, Rhizobium, which can be applied in the treatment of the soil, to maximize the crop yield and find out the most treatment combination of plant growth, yield and quality. This study was conducted in the horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj (UP) from July 2021- October 2021 to investigate the impact of organic, inorganic, and biofertilizers on the growth, yield, and quality of cluster beans (Cyamopsis tetragonaloba L.). The experiment was laid out in RBD with nine Treatmentsconducted in the horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj (UP) During from July 2021- October 2021. The experiment was laid out in RBD with nine treatments with three replications. The results revealed that T8 (N20P50K50 Vermicompost 5 t ha-1 + PSB 5 kg ha-1 + Rhizobium 5 kg ha-1) – performed the best in terms of Plant Height (140.22), Number of Branches (21.39), Length of Pods (25.00), Width of Pods (3.70), Weight of Pods (4.10), Number of cluster per plant (21.60), Number of Pods per plant (89.17), Number of seeds per pod (11.80), Number of Pod yields per plant (196.87), Number of pod yield per plot (68.03), TSS (12) B:C Ratio (2.5:1). Therefore, the treatment T8 (N20P50K50 Vermicompost 5 t ha-1 + PSB 5 kg ha-1 + Rhizobium 5 kg ha-1) is the best when compared to other treatments. As, the highest benefit cost ratio was observed in T8 (N20P50K50 Vermicompost 5 t ha-1 + PSB 5 kg ha-1 + Rhizobium 5 kg ha-1). i.e., (2.5:1) which states that is economically profitable compared to all other treatments.
