Title: Evaluation of William's Banana (Musa Cavendish L.) Clones Under Hot Arid Climates of the Sudan
Author: Fatima Abdel Raouf Ahmed Abdel Hameed
Abstract: Five experiments were carried out at the experimental field of Shambat Agricultural Research Station to study the performance of irradiated Williams Banana clones (Musa AAA Cavendish subgroup), the response of banana clone W-193/3 to fertilizers application, performance of conventional and tissue cultured planting material and the effect of desuckering stage on its growth, yield and yield components under field conditions for three crop cycles. Four plants were planted per plot (5×5m) at spacing of 2.5×2.5m. Treatments were arranged in a randomized complete block design with four replications. Data were vegetative and fruiting characteristics and yield and yield components were collected during the three crop cycles. The results indicated that Clone W-193/3 produced significant increase in vegetative growth, yield, yield components, longer fingers with less curvature and significantly had higher in sugar content, dry matter, peel to pulp ratio and had the longest green life and significantly XIII early in flowering and gave shortest time to harvest, compared with other clones and origin Williams and Dwarf Cavendish cultivars. Tissue culture derived plants resulted in significant early flowering, better vegetative growth and greater yield for the crop cycle compared to conventional planting materials. There was no significant difference in the morphological data in the first and second ratoon between tissue culture derived plants, sword and maiden sucker plants; the three types produced significantly greater yield and yield components and they were significantly early in flowering and gave shortest time to harvest, than other planting materials. Finger length did not differ significantly in tissue culture derived plants and conventional sucker plants in the three cycles. Nitrogen application at seven level ( 0, 46, 92, 138, 184, 230 and 276 g/mat ) in the form of urea were compared throughout the three successive cycles. The response was similar during the three seasons. Maximum yields, vigorous growth and significant short time to flowering and to harvest were attained at 138 and 184g/mat compared to other treatments. In these nitrogen levels the leaf lamina content of nitrogen and potassium were equal (3.3%), indicating the importance of a balanced fertilization regime. Finger length and curvature did not differ significantly in all treatments. XIV Foliar fertilizer Borxal with five concentration levels (0, 5, 10, 15, 20 ml/L), showed that, Plants receiving Borxal at 15ml/l concentrations were significantly early in flowering and gave shortest time to harvest, greater increases in vegetative growth, yield and yield components compared to the other treatments, over the three cycles. The application of 15ml/l was optimum and had a significant carry over effect with leaf lamina N content of 3.3%. Potassium leaf content increased with higher N PK applications. Finger length and curvature were not affected in all nitrogen treatments. The results of desuckering at different stage (150,200,300.400 and 1000 mm) showed that significant increased in vegetative growth, yield and yield components and gave shortest growth cycles and time to harvest, when unwanted suckers removed at 150 and 200 mm height compared to the other treatments. Finger length and curvature of clone 193/3 were not significantly affected by all treatments.
