Effect of phosphorus levels and varieties on yield and yield attributes of mung bean (Vigna radiata) in climate condition of Badghis, Afghanistan

A field experiment was conducted during the spring season of 2020 at research farm of Badghis Institute of Higher Education, Badghis, Afghanistan to evaluate the effect of phosphorus levels and varieties on yield and yield attributes of mung bean [Vigna radiata (L.) R. Wilczek]. The experiment was laid out in a randomized complete block design with 3 replications. The experiment was comprised 2, viz. varieties ‘Mai 08’ and ‘Nayab 98’ of mung bean with 4 phosphorus levels, viz. control, 40, 60 and 80 kg P2 O5 /ha. The results revealed that, mung bean crop fertilized with 80 kg/ha P2 O5 gave the maximum branches/plant (6.4), pods/plant (24.88), pod length (6.28), seeds/ plant (243.3), 1,000-grain weight (32.74), grain yield (1230.43 kg/ha), and harvest index (39.42). Phosphorus @ 80 kg P2 O5 /ha was found more economical for getting higher grain yield of mung bean crop. The maximum and higher number of branches/plant, number of pods/plant, number of seeds/plant, 1,000-grain weight, grain yield kg/ ha, and harvest index were recorded with ‘Mai 08’ variety
