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).
A field experiment was conducted during autumn season 2018 at Al Salam district, Maysan governorate. The aim was to evaluate some growth properties and grain yield of three varieties of cowpea, Vigna sinensis L. (Local, Patton Boa and Atta E) grown under different levels of potassium sulphate (0, 43, 86 and 129 kg h-1). The experimental design was applied according to the random complete block design in a split arrangement (Split Plots in RCBD). In on hand, the results showed a significant differences between the varieties. The local variety significantly gave highest plant length , leaf area, pods number, seeds number pod-1 and grain yield and which were 60.75cm, 2936.81cm2, 39.60 pod. plant-1, 7.69 seed pod-1, 99.93 g and 4.16 t. h-1 respectively. While the varieties Baton Boa gave highest weight of 100 seeds and gave 37.58 g. In other hand, as compare to the control, the addition of potassium up to 129 kg. h-1 lead to significant increase in plant length, leaf area, pods plant-1, seeds number pod-1 and grain yield plant-1 and total grain yield which were 53.33 cm, 3455.91 cm2, 51.61 pod. plant-1, 8.76 seed. pod-1, 125.93 g. and 5.25 T.h-1 respectively. Whereas, the control treatment (K0) gave the highest weight of 100 seeds (45.11 g). The Interaction between varieties and potassium had a significant effect on almost growth and yield characteristics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
