Effect of Irrigation Intervals on Growth and Yield of Broad Bean (Vicia faba .L)

Abstract

The experiment was carried out to study the effect of irrigation intervals on the growth and yield of Broad Bean genotype (Hadeiba 93), Experimental Farm, College of Agricultural Studies, Sudan University of Science and Technology in Shambat from November 2017 to February 2018. using system of randomized complete block design(RCBD), in four replicates and three treatments (7 ,14 and21 days) .Three growth characteristics were measured : plant height ,the number of leaves per plants and the number of branches per plants and five components of productivity were measured: including number of plants per square meter, number of pods of plants per square meter, seed production per square meter,100-seedweight and productivity kilo gram per Fadden .The results showed that there were significant differences between the irrigation intervals for some of the characteristics :seeds of production per square meter, the number of pods per plants, and the yield kilo gram per Fadden. The results also showed no significant differences some characteristics: plant height, number of leaves, number of branches per plant, number of plants per square meter and the weight of 100 seed .The results showed that the irrigation interval every 7 days gave the highest productivity.
