Assessing the Effect of Phosphorus, Molybdenum and Rhizobium Inoculation on Growth, Yield and Yield Attributes of Mungbean. (Vigna radiata L.) under Rainfed Conditions

Abstract

An experiment was carried out during Kharif season of 2023 at Pot Culture experimental site, Department of Soil Science and Agricultural Chemistry, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur Nagar (U.P.). The experiment was laid out in Randomized Block Design with thirteen treatments each replicated thrice. The treatments consist of three levels of phosphorus viz., 20 kg ha-1, 40 kg ha-1 and 60 kg ha-1, two levels each of molybdenum viz. 1.0 kg ha-1 and 2.0 kg ha-1 and Rhizobium viz. inoculated (Rh1) and uninoculated (Rh0). Mungbean variety IPM 02-3 was grown with recommended agronomic practices under rainfed conditions. On the basis of the results emanated from the investigation, it is observed that, application of treatment T12 [P60 + Mo1 + Rh1] resulted in significantly higher plant height (58.24 cm), no. of branches plant-1 (9.82), no. of pods plant-1 (25.84), length of pod (8.91 cm), no. of seeds pod-1 (11.45), test weight (49.86 g) and seed yield (11.78 q ha-1). While the application of T13 [P60 + Mo2 + Rh1] resulted in significantly higher no. of leaves plant-1 (5.52), no. of nodules plant-1 (29.6) and stover yield (23.04 q ha-1). Thus, it could be concluded that treatment T12 [P60 + Mo1 + Rh1] was found to be superior and subsequently at par with treatment T13 [P60 + Mo2 + Rh1] over all the other treatments.
