Response of Three Indigenous Pulse Crops to Different Moisture Conditions

Abstract

A field experiment was conducted in the Demonstration Farm
of the Faculty of Agriculture, University of Khartoum for two seasons
(January to May 2005 and December 2005 to May 2006). The objective
of the experiment was to study the effect of 7 and 14 days irrigation
intervals on growth and yield of three local pulse crops; namely, Vigna
unguiculata ‘Lubia Hilu’, V. sinensis ‘Lubia Kordofani’ and Lablab
purpureus ‘Lubia Afin’. The results showed that irrigation every 14 days
reduced dry matter production and seed yield, but increased the
percentage of crude protein in the seeds of the three crops as a result of
increase in the ratio proteins: carbohydrates
