Abstract:
An experiment entitled "Testing of comparative efficacy of different Rhizobium inoculants on growth and yield of soybean" was conducted in Kharif season at student research field, College of Agriculture, Indore (M.P.). The soil of the experimental field was medium black in texture, neutral in reaction (pH 7.70) with normal EC (0.23 dS/m) and medium organic carbon contents (0.56 %) and analysing low in available N (225 kg/ha), medium in available P (9.60 kg/ha) and high in available K (508 kg/ha) contents. Due to dominance of montmorillonite clay content it has high capacity to swell and shrink and high CEC. A field experiment was consisted of 15 treatments replicated four times in randomized block design (RBD). As per treatment, the seed of soybean cv. JS 335 treated or not treated with fungicides and inoculated with Rhizobium culture before 15, 10, 05, 01 days of planting and on the day of sowing. The maximum number of nodules (63.90/plant) was recorded under [Thiram + Carbendazim 50 WP - Premax+ Rizo-liq (ODS)] (T10) treatment while minimum number of root nodules (51.20/plant) was recorded in T15 absolute control (No fungicide, No culture). Maximum yield (2147 kg/ha) was recorded under [Thiram + Carbendazim 50 WP - Premax+ Rizo-liq (ODS)] (T10) treatment and the minimum (1509 kg/ha) was recorded in absolute control (T15) treatment. The application of Rhizobium with or without fungicides showed a synergic effect in increasing the seed yield of soybean per hectare. The maximum net return (Rs.16030/ha) as well as the benefit; cost ratio (2.72) were obtained from T10 having [Thiram + Carbendazim 50 WP - Premax + Rizo-liq (ODS)] treatment as compared to absolute control (T15) treatment where as minimum net return (Rs.9035/ha) and the benefit; cost ratio (2.03) were obtained.
