Effect of spacing and integrated nutrient management on yield attributes, yield and quality of cluster bean (Cyamopsis tetragonoloba L. Taub) cv. Pusa Navbahar

Abstract

An investigation entitled “Effect of spacing and integrated nutrient management on yield attributes, yield and quality of cluster bean (Cyamopsis tetragonoloba L. Taub) cv. Pusa Navbahar” was carried out during year 2018 at Horticulture Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand. An investigation was laid out in Randomized Block Design (Factorial) with 3 replications and fourteen treatments combination comprising of two levels of spacing viz., S1: 45 × 15 cm and S1: 30 × 15 cm and seven level of integrated nutrient management viz., F1 - 25:50:00 NPK kg/ha (Control), F2 - 30:60:00 NPK kg/ha, F3 - 50% RDN through inorganic fertilizer + 50% RDN through FYM + seed treatment of Rhizobium and Phosphate solubilizing bacteria (each 5 ml/kg of seed), F4 - 50% RDN through inorganic fertilizer + 50% RDN through vermicompost + seed treatment of Rhizobium and Phosphate solubilizing bacteria (each 5 ml/kg of seed), F5 - 20:40:00 NPK kg/ha + seed treatment of Rhizobium (5 ml/kg of seed), F6 - 20:40:00 NPK kg/ha + seed treatment of Phosphate solubilizing bacteria (5 ml/kg of seed), F7 – 20 : 40 : 00 NPK kg/ha + seed treatment of Rhizobium and Phosphate solubilizing bacteria (each 5 ml/kg of seed). Spacing showed significant effect on yield and quality parameters. However, green pod weight (g) and fiber content (g/100g) did not observed any significant effect of spacing. Spacing 45 × 15 cm (S1) recorded maximum number of cluster/plant, number of pods/cluster, number of pods/plant, green pod length, green pod yield (g/plant) and crude protein (%) whereas, green pod yield (kg/plot) and green pod yield (t/ha) was found maximum in Spacing 30 × 15 cm (S2). Maximum number of cluster/plant, number of pods/cluster, number of pods/plant, green pod yield (g/plant), green pod yield (kg/plot) and green pod yield (t/ha) was recorded with treatment F4 [50% RDN through inorganic fertilizer + 50% RDN through vermicompost + seed treatment of Rhizobium and Phosphate solubilizing bacteria (each 5 ml/kg of seed)]. While, maximum green pod length (cm) and crude protein (%) was observed with treatment F3. While, green pod weight and fiber content found non-significant difference. Interaction effect between S1F1 recorded maximum number of clusters/plant.
