Experiments were carried out in Damazin Research Station during summer 2016 and 2017 to determine the effect of intra-row spacing on two eggplant (Solanum melongena L.) cultivars growth and yield. The treatments used are three intra-row spacing viz. 30, 40 and 50 cm with two cultivars (Wizo and black beauty), the experiments were arranged in a Randomized Complete Block Design with three replications. The data collected including growth and yield parameters was analyzed using the GenStat statistical package. Results show that that Wizo cultivar recorded the best statements than black beauty cultivar. The wide spacing (50 cm and 40) intra-row spacing recorded the highest number of leaves/plant, number of fruits/plant and fruit length (cm). The 30 and 40 cm intra-row spacing and Wizo gave the greatest yield (tons/ha) in two seasons. The study advised to use Wizo cultivar and 40 cm intra row-spacing is appropriate to cultivate eggplant in Blue Nile State Sudan.

Experiments were carried out at Damazin Research Station farm during kharif season 2016 and 2017, to evaluate the effects of bulb set girth and plant density on growth, yield and characters of onion under rain-fed condition. Treatments include three factor of factorial combinations of two bulb set size girth (1-2 and 2-3 cm) ,intra-row spacing vis 7.5 and 10 cm and number of rows ridges-1 (two and three rows ridges-1). Results show that bulb set girth and plant density was effects on growth, yield and quality of onion. Results showed that The greatest yield tons ha-1 was obtained by large set when grown at 10 cm intra-row spacing three rows ridges-1 in both seasons.
