Effect of Watering
Regimes at Two Stage of Growth on Faba Bean Grain Yield at Selaim Basin
E. D. Balasio , A. Hussein1 and M. A. Ahmed
Abstract:
The study was carried out in farmer’s field in Selaim basin for two
consecutive seasons (2000-01 and 2001-02) to study the response of faba
bean to differential irrigation in relation to two stages of growth on
grain yield and the incidence of insect pests on the crop. Three
watering regimes (14, 21and 28-day intervals) were interchanged in all
possible combinations during the two phases of plant growth (vegetative
and reproductive). The resultant nine treatment combinations were
replicated four times in a randomized complete block design (RCBD).
Variety SM-L was sown and sprayed with Folimat E.C (1ml L-1 of water)
against insect pests. In both seasons treatment C1 (28 days-vegetative
and 14 days-reproductive) gave the highest grain yield (3545 kg ha-1 and
2631 kg ha-1) in the first and the second seasons, respectively.
Treatment (C1) received only six irrigations with a total quantity of
irrigation water of about 4464 m3 ha-1 compared to irrigating 14 days
throughout the growing season, which consumed about 7429 m3 ha-1 in
eight irrigations. Two irrigations were saved with a total quantity of
water equal to 2965 m3. Consumptive water use was less at the early
vegetative and late growth stages and greater at middle stages.
