ABSTRACT
A field experiment was conducted during summer season 2018 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) to evaluate the effect of PSB inoculation with and without P and S application. The area situated at a latitude of 290 4’ N and longitudes of 770 42’ E with an elevation of 237 m above mean sea level. The soil of experimental field was well drained, sandy loam in texture, alkaline in reaction (7.82), low in available nitrogen and sulphur, medium in available phosphorus and potassium with an electrical conductivity of 0.21 dS m-1. Thirteen treatments comprising control, inoculation of PSB with and without P and S application were tested in RBD with three replications. The crop was grown with recommended package and practices for mungbean with exception of phosphorus and sulphur application which was variable as per treatments. The data on growth, yield and its contributing traits content and uptake of nutrients at harvest stage along with available N, P, K, S and bulk density of soil were estimated as per the standard procedures. The experimental results revealed that growth parameters (plant population, plant height, primary branches plant-1, nodules and their dry weight plant-1 and dry matter accumulation plant-1), yield attributing traits viz. number of pods plant-1, number of grains plant-1, grain yield plant-1, test weight and biological yield, grain yield, straw yield and content and uptake of N, P, K and S in mungbean differ significantly among different treatments. Growth parameters were significantly better in the treatment T13 (PSB + 40 kg P2O5 ha-1 + 30 kg S ha-1). The highest grain yield was recorded in T13 where 40 kg P2O5 ha-1 + 30 kg S ha-1 was applied with inoculation of PSB. This treatment was statistically at par with T12. Growth and yield attributing characters were comparatively higher in T13. Available nutrients in soil and physico-chemical properties of soil after harvest of mungbean were variable under different treatments. From the study it may be concluded that the application of 40 kg P2O5 ha-1 + 30 kg S ha-1 with PSB inoculation (T13) gave best results (Grain yield increased by 13.2%, 15.2%, 4.7% and 100.2% over T2, T4, T12 and T1, respectively) and proved to be beneficial for summer mungbean. Application of 40 kg P2O5 ha-1 + 15 kg S ha-1 with PSB inoculation (T12) also gave better results, besides saving of 15 kg S ha-1. The balanced and combined use of P and S along with PSB in mungbean improved the growth attributes, total uptake of nutrients along with maintaining the soil fertility balance.
