Response of Sorghum (Sorghum bicolor L. Moench) Genotypes to Different Levels of Agricultural Sulfur

A field experiment was conducted in agricultural research station which is located at Al-Qurna district, 75 km north of Basrah governorate during the autumn season 2018. The aim was to study the effect of agricultural sulfur (0, 3, 6 and 9 t S.ha-1) on growth and yield of three sorghum genotypes (Inkath, Rabeh and Kafier2). The experiment was conducted as randomized complete block design in a factorial arrangement with three replications. The results showed that there were significant differences among the genotypes. The genotype kafier2 gave the highest average of plant height of 171.5 cm while the genotype inkath gave the highest weight of 1000 seed (25.59 gm), grain yield (3.97 t.ha-1). Genotype rabeh produced highest average of leaf area index and number of grain head of 3.10 and 1994.41 grain.head-1 respectively. The agricultural sulfur showed significant effect on most studied traits of sorghum (plant height, leaf area index, grain head, weight of 1000 grains and grain yield). The addition of agricultural suffer up to 9 t. ha-1 increased grain yield and produced 5.80 t.ha-1. The interaction of genotypes and agricultural sulfur showed a significant effect on some traits of growth and grain yield. The genotype inkath supplied with 9 t.ha-1 of agricultural sulfur resulted in highest grain yield of 5.80 t.ha-1, while the genotype rabeh supplied with 6 t.ha-1 of agricultural sulfur gave the highest average of leaf area index (3.54) and number of grains head (2106.33 grain.head-1).
