Title: Effect of Watering Intervals on Growth and Forage Yield of Millet (Pennisetumglaucum) and Some Sorghum (Sorghum bicolor) Genotypes
Author: Almofty, Lamia AbdAlla Mohammed Ali
Abstract: A field experiment was conducted during 2014season in the Demonstration Farm of the Faculty of Agriculture, University of Khartoum, Shambat, Sudan to evaluate the effect of different watering intervals on the performance of five foragesorghum genotypes and pearl Millet(Ugandi type). The treatments consisted of three irrigation intervals, 7, 15 and21days and five forage sorghum genotype,Tabat, Abu 70, Wad Ahmed, Pioneer and Butana, with Pearl Millet crop. The experiment was laid out in split-plot design with four replications. The parameters measured were plant height, number of leaves/plant, number of tillers/plant, stem circumference (cm), root length, fresh and dry forage yield. The Results showed that increasing watering intervals significantly (P≤ 0.05) reduced plant height after 90 and 105 days from sowing. Number of leaves per plant, number of tillers /plant, stem circumference and root length were not significantly affected by watering interval. Abu70, Pearl Millet and Pioneer were significantly taller than the other sorghum genotypes. The number of leaves per plant were significantly (P≤ 0.05) higher for Pioneer and Abu 70 and lower for Butana and Wad Ahmed at 60 days. However, after 75, 90 and 105 days from sowing, the difference in number of leaves per plant among sorghum genotypes and millet was not significant. The sorghum genotypes and Pearl Millet were not significantly different in number of tillers per plant. Stem circumference was significantly (P≤ 0.05) highest for Abu 70 and lowest in Pearl Millet at 75 days from sowing. Wad Ahmed, Abu 70 and Tabat gave the longest root. Although the effect of water interval on forage fresh and dry yield was not significant, irrigation every 7 days gave higher forage fresh and dry yield. The difference in forage fresh yield among the sorghum genotypes and Pear Millet was not significant, but Pear Millet gave higher forage fresh yield. Pearl Millet was significantly (P≤ 0.05) higher in forage dry yield followed by Abu 70. significant is The study concludes that shortening irrigation interval gives better growth and higher forage yield, and Pearl Millet and Abu70 are best for forage yield. Hence the recommendation is to grow Pearl Millet using irrigation intervals of 7-15 days for forage production
