Effect of some tillage and seeding methods on the yield of grain sorghum under mechanized rainfed conditions

Amir Bakheit Saeed and Hassan Yousif Eissa

Abstract:

Three sorghum seeding methods were interacted with four tillage treatments for improving sorghum yield under mechanized rainfed conditions of Sam Sam area, southern Gadarif, for two seasons (1999/2000 and 2000/2001). The results indicated that there were no significant differences for the interaction of tillage treatments with the three seeding methods with respect to days to crop emergence, plant height and 100 seed weight. The interaction of the tillage treatments with culti-planter seeding method recorded higher plant population, crop establishment and fewer days to 50% flowering and consequently out yielded other seeding methods. Soil moisture content before seeding, was significantly higher for the offset disc and chisel ploughing tillage treatments. The results also showed that the offset disc harrow ploughing and the culti-planter seeding indicated highest operational costs. On the other hand, the lowest cost was recorded by no tillage and the wide level disc (W.L.D) seeding. Moreover, the results also indicated that the highest return was given by the chisel ploughing and the culti-planter seeding and the lower return was recorded by the W.L.D when used for both operations.
Generally, the culti-planter seeding gave the best returns as compared to other seeding machines.
