Influence of foliar application of nitrogen on growth and yield of mungbean (Vigna radiata) varieties in Kandahar region of Afghanistan

A field experiment was conducted during April-July 2017 at the Afghanistan National Agricultural Sciences and Technology University (ANASTU), Kandahar, Afghanistan to find out the influence of 2 mungbean (Vigna radiata L. Wilczek) varieties viz. ‘Mash 2008’ and ‘NM 94’ and 7 methods of N applications, viz. absolute control, basal application of 25 kg N/ha, foliar application of 2% urea through single application at 40, 50 and 60 days after sowing (DAS), 2 times foliar application at 50 and 60 DAS and 3 times foliar application of 2% urea spray at pre-flowering (40 DAS), flowering (50 DAS) and pod development (60 DAS) on crop growth and productivity. The results showed that the variety ‘Mash 2008’ resulted superior performance in respect of plant growth and yield attributes to ‘NM 94’ mungbean. The findings of present study showed that the 3 times foliar of 2% urea at pre-flowering + flowering + pod development stages (40, 50 and 60 DAS) may be adopted for ‘Mash 2008’ variety to get the superior plant growth, yield attributes and yields of mungbean in semi-arid conditions of Afghanistan.
