Influence of summer mungbean genotypes on grain yield and resource-use efficiency in Kandahar province of Afghanistan

Abstract

A field experiment was conducted at Experimental Farm of Afghanistan National Agricultural
Sciences and Technology University (ANASTU), Kandahar, Afghanistan during April-June, 2015
to work-out the grain yield and resource-use efficiency of mungbean varieties viz. Mai-2008, Mash-
2008, NM-94, NM-98 and local cultivar 'Kunduzy' under semi-arid conditions of Kandahar. The
results indicated that Mash-2008 exhibited significantly highest grain yield while Kunduzy exhibited
minimum seed yield. The Mash-2008 yielded 5.0, 34.9, 34.5 and 48% more yield as compared to
Mai-2008, NM-98, NM-94 and 'Kunduzy', respectively. The mungbean genotypes showed significant
differences for total water-use efficiency (TWUE), irrigation water-use efficiency (IWUE) and
economic water productivity (WPE). Mash-2008 exhibited highest TWUE (9.9 kg ha–1 mm–1), IWUE
(10.6 kg ha–1 mm–1) and WPE (644 AFN ha–1 mm–1) while 'Kunduzy' recorded minimum TWUE (6.7
kg ha–1 mm–1), IWUE (7.2 kg ha–1 mm–1) and WPE (434 AFN ha–1 mm–1). Overall, Mash-2008
outperformed in terms of grain yield, production-efficiency, monetary-efficiency, total water-use
efficiency (TWUE), irrigation water-use efficiency (IWUE) and economic water productivity (WPE)
over other mungbean cultivars in semi-arid conditions of Afghanistan.
