Effect of foliar application of micronutrients on summer mungbean varieties on alluvial soil of West Bengal

Abstract

A field experiment was carried out during the summer seasons of 2020 and 2021 at Jaguli Instructional Farm, BCKV, Nadia (West Bengal), in the Gangetic alluvial soil, to assess the effect of varieties and micronutrient foliar spray on growth parameters, yield components, yield and economics of mungbean. Results revealed that different varieties significantly promoted growth parameters and variety Meha was found to be superior. Growth parameters was significantly higher under molybdenum foliar spray over other micronutrients foliar spray. The maximum number of pods per plant, pod length, seeds per pod and test weight were found in plants receiving sodium molybdenum foliar spray at 0.05%. Maximum seed yield and stover yield were also recorded in the same treatment where 0.05% sodium molybdenum spraying was done at pre flowering and pod development stage. Variety showed significant variation in pods per plant, pod length, seeds per pod and test weight and were maximum in variety Meha. Both seed and stover yield were highest in case of variety Meha over others. The gross returns, net returns and benefit: cost ratio were maximum in Meha variety with foliar application of sodium molybdenum. Hence, variety Meha with foliar spray of molybdenum could be more effective in augmenting mungbean growth, yield and economics in the Gangetic plains of West Bengal in the summer season.
