ABSTRACT
A field experiment was conducted to assess the effect of inorganic fertilizer, biofertilizers, microbial consortia inoculation on yield and quality of Yardlong bean. The study was conducted under naturally ventilated polyhouse during Kharif 2021-22 at Zonal Agricultural and Horticultural Research Station, Shivamogga, Karnataka, The experiment was laid out in Randomized complete block design (RCBD) with three replications and eight treatments viz., T1 – 100 % Recommended Dose of Fertilizer (RDF-25:75:60 NPK, kg ha-1 ), T2 -100 % RDF + Effective Microbial Consortia (EMC)+ Vegetable Special (VS) , T3 - 125 % RDF, T4 - 150 % RDF, T5 - 175 % RDF, T6 - 125 % RDF + EMC+ VS , T7 – 150 % RDF +EMC+VS , T8 - 175% RDF+EMC+ VS. The integrated treatment combinations involve both organic and inorganic source of nutrients which significantly influenced the growth and yield parameters. The results revealed that, all the growth and yield parameters were markedly influenced by the integrated nutrient management treatments. Among different treatments, significantly higher plant height (246.33), number of primary branches (8.42), initiation of flowering (38.08d), fifty percent flowering (43.22 d), days to first harvest (52.58 d), number of pods per plant (24.83), pod length (74.00 cm), pod girth (3.88 cm), average pod weight (35.00 g), yield per plant (643.33 g) and higher pod yield per 1000 m2 (2135.42 kg) were recorded with treatment 150% RDF + EMC+ VS. The workout of cost economics shows that growing of Yardlong bean with treatment (T7) could be the most remunerative option with a highest benefit: cost of 3.23.Thus Integrated Nutrient Management practices increased the growth and yield of Yardlong bean and among compared treatments, T7 – 150% RDF + Effective Microbial Consortia (EMC) + Vegetable Special (VS) found to achieve the maximum productivity & profitability of Yardlong bean.
