Effect of fungicide and different Rhizobium inoculants on growth and yield of soybean (Glycine max (L.) Merrill)

Abstract

An experiment was carried out at in Kharif season at student research field, College of Agriculture, Indore (M.P.) to study the Effect of fungicide and different Rhizobium inoculants on growth and yield of soybean (Glycine max (L.) Merrill). 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. 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. Among the treatments, seed treatment with Thiram + Carbendazim 50 WP – inoculation with Premax+ Rizo-liq (ODS)] (T10) recorded the maximum plant height (66.75 cm) at harvest, branches per plant (4.02), fresh weight (35.83 g) per plant at 75 DAS, dry matter per plant (23.14g) at 75 DAS, leaf area index (12.87) at 60 DAS, number of pods (39.18) per plant, number of seeds (2.84) per pod while minimum was recorded in T15 absolute control (No fungicide, No culture). The maximum yield (2.15 t/ha) was recorded under [Thiram + Carbendazim 50 WP - Premax+ Rizo-liq (ODS)] (T10) treatment and the minimum (1.51 t/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.
