Yield and Nutritional Status of Mungbean as Influenced by Molybdenum and Phosphorus

Abstract

Legumes are most important crops after cereals having provide a range of essential nutrients and nitrogen fixation for soil fertility particularly for the subsequent crops and yield productivity. In order to improve the nutritional profile of mungbean a study was arranged at Agronomy Research Farm, Agriculture University of Peshawar in summer season 2018. The objectives of the study is to find out impact of different doses of molybdenum and phosphorus application on productivity and nutrients status of mungbean (Vigna radiate L.). The trial was laidout in randomized complete block design having three replicates. The experimental findings revealed that all the nutritional attributes and yield were significantly influenced with molybdenum and phosphorus addition except potassium uptake by grains and straw. Higher seed yield (772.45 kg ha -1 ) and harvest index (26.18 %) with application of 1.5 kg ha -1 molybdenum while more protein content (21.91 %), carbohydrates (60.36 %), nitrogen content in grain (3.76 %) and straw (1.10 %), phosphorus uptake in grain (0.380 %) and straw (0.186 %) was achieved with molybdenum applied at rate of 2.5 kg ha -1 . Whereas in case of phosphorus use maximum seed yield (810.88 kg ha -1 ) and harvest index (26.92 %) was observed with 60 kg ha -1 P application while highest protein content (22.08 %), carbohydrates (60.37 %), nitrogen content in grain (3.60 %) and straw (1.19 %), phosphorus uptake in grain (0.418 %) and straw (0.21 %), potassium uptake in grain (1.96 %) and straw (1.30 %) was achieved with P applied at 90 kg ha -1 . Higher doses of phosphorus and molybdenum enhance all the quality attributes of mungbean. It concluded from the experimental findings that mungbean crop with (1.5 kg ha -1 Mo and 60 kg ha -1 P) for seed yield and (2.5 kg ha -1 Mo and 90 kg ha -1 P) for enhancement of nutrients uptake of mungbean performed better than other doses and thus recommended for higher productivity and qualitative attributes in agro climatic condition of study area.

Effectiveness of compost inoculated with phosphate solubilizing bacteria

“…≤7.0 mg kg −1 ). Phosphorous deficiency has been reported to cause severe reduction in productivity of onion, olive and mungbean crop in Pakistan (Ahmad et al, 2021; Jan et al, 2021; Qazi et al, 2021). It is not surprising that PSB can be used as biofertilizers which is an environmental‐friendly and sustainable approach that enhances the efficiency of P fertilizers (Castagno et al, 2021).…”
