Effect of varieties and planting geometry on growth, yield and profitability of Kharif mungbean (Vigna radiata (L.) Wilezek] in southern Afghanistan

摘要

An experiment was conducted at Tarnak Farm of Afghanistan National Agricultural Sciences and Technology University (ANASTU), Kandahar, Afghanistan during Kharif 2015 to assess the performance of mungbean varieties viz. Mai-2008, Mash-2008, NM-98 and local culnvar Kunduzy' in combination with 3 planting geometries (20x10,30x10, and 40x10 cm) under semi-arid conditions of Kandahar. It was revealed that mungbean varieties and planting geometries showed significant differences for growth, morpho-physiological and yield parameters. Mash-2008 exhibited highest seed yield (2031 kg ha~(-1)) while Kunduzy led to lowest seed yield (1297 kg ha~(-1)). Mash-2008 yielded 7.8, 33 and 56% higher than Mai-2008, NM-94 and 'Kunduzy', respectively. Planting geometry of30x10 cm exhibited higher seed yield (1898 kg ha~(-1)) followed by 20x10 cm (1641 kg ha~(-1)). Mash-2008 produced maximum straw yield while 'Kunduzy' produced minimum straw yield. Highest gross (AFN 86665 ha~(-1)) and net returns (AFN 67672 ha~(-1)) andB: C ratio (456) were observed in Mash-2008. Among planting geometries, maximum gross and net returns and B: C ratio were observed in 30x10 cm spacing followed by 20x10 cm and 40x10 cm spacing. Overall, Mash-2008 under planting geometry of 30x10 cm ledto higher growth, crop productivity and profitability followed by Mai-2008 at 30x10 cm spacing in Kharif mungbean crop under semi-arid conditions of Afghanistan.
