Abstract

In Hararghe as whole, intercropping is the main and indigenous activity of the farmers due to land shortage that most farmers are practicing intercropping of different crops for different reasons like to minimize total crop failure and efficient land utilization. An experiment was conducted to evaluate the influence of sowing dates of Dolichos lablab intercropping with sorghum on sorghum yield and yield related and to identify the optimum sowing date of Dolichos lablab intercropping with sorghum in West Hararghe Zone, Oromia, Ethiopia. Six treatments, namely: sole lablab, sole sorghum, Sorghum + lablab simultaneous, Sorghum + lablab after two weeks, Sorghum + lablab after four weeks and Sorghum + lablab after six weeks were used with 3 replications in a randomized complete block design. Significant (p<0.05) variation were observed between 50% flowering, plant height, stand count at harvest, sorghum yield, and plot cover but has no significant (p>0.05) in terms of sorghum maturity and diseases incidence. The highest mean sorghum seed yield (20.61qt/ha) was obtained from sole sorghum followed by sorghum + lablab after four weeks intercropped while the lowest seed yield (10.82qt/ha) was recorded from Sorghum + lablab simultaneous intercropped. The study showed that sorghum-lablab intercropped at different sowing date has influence on grain yield of sorghum that grain yield of sorghum increases as sowing date of lablab increases. The ideal acceptable LER was produced from sorghum + lablab intercropped after four weeks. The highest mean grain yield of lablab yield (19.9 qt/ha) were recorded from sorghum + lablab simultaneous intercropping whereas the lowest mean grain yield (4.2 qt/ha) was recorded from sorghum + lablab after six weeks intercropped. The largest lablab dry matter yield (2.31 t/ha) was recorded from sorghum + lablab after four weeks whereas the lowest (2.15 t/ha) was recorded from sorghum + lablab after six weeks intercropped. Therefore, it recommended that four weak after sown of sorghum is the appropriate date of sorghum-lablab intercropping.
