Abstract
A field experiment was conducted at the Horticultural Research Farm, B. A. College of Agriculture, Anand Agricultural University, Anand during Kharif season of the year 2004 with the objectives of studying the "Effects of Biofertilizers and Chemical Fertilizers on Growth and Yield of Vegetable Cluster bean (Cyamopsis tetragonoJoba (L). Taub) cv. Pusa Navbahar" with ten treatments in a Randomized Block Design, which are replicated three rimes. The results indicated that the growth and yield parameters were significantly affected by different biofertilizers and chemical fertilizers. The treatment T9 (25 kg N/ha + 50 kg P2O5/ha + Rhizobium + PSB inoculation) recorded significantly the highest plant height (56.48 cm), (151.85 cm) at 50 % flowering and at harvest, respectively. The treatment T9 had also recorded highest RGR i.e. 0.06 and 0.04 g/g/day) at 45 DAS and 75 DAS, respectively. Different yield parameters vi%., emergence of first flower, days to 50 % flowering per plot, green pod yield per plant, per net plot and per hectare were found to be significant with different combinations of bio fertilizers and chemical fertilizers. The treatment T9 (25 kg N/ha + 50 kg P2O5/ha Rhizobium + PSB) recorded the minimum days for emergence of first flower (30.33 days), which was found at par with treatments T3 and T6. Further this treatment had also recorded minimum days taken for 50 % flowering (38.00 days) followed by treatment T3. The significantly maximum no. of pods per cluster (11.04), maximum no. of clusters per plant (19.72) was also recorded under treatment T9 which was followed by treatments T3, T8, T6 and T2 respectively. Further maximum pod length (13.03 cm) was obtained under T9, which was followed by treatment T3. The green pod yield per plant (396.00 g) per net plot (9.05 kg) and per hectare (22.88 t) were found significantly maximum under the treatment T8 which was followed by T3, T6 and T8, respectively. The maximum net realization of Rs. 51291 per hectare was recorded with the treatment. T9 (25 kg N/ha + 50 kg P2O5/ha + Rhizobium + PSB) with highest C.B.R. (1 : 2.28) as compared to rest of the treatments. Results obtained from this investigation, it is reveled that the seeds of cluster bean should be inoculated with Rhizobium and Phosphorus Solubilizing Bacteria (PSB) along with the application of 25 kg N ha-1 and 50 kg P2O5 ha-1 for getting maximum green pod yield and net profit for vegetable purpose cluster bean under middle Gujarat agro-climatic condition.
