Study the effect of residues (palm, peanut, tea) in the characteristics of vegetative growth and yield of onion plant (Allium Cepa L)

摘要

The effect of residues was studied (palm, peanut, tea) in the characteristics of vegetative growth and the bulb onion in addition to the total yield OF onion plant (Allium cepa L) in El Oued zone (Algeria) during in 2016 season. An investigation was a randomized complete block design in three replications. The obtained results of experiment showed that: response the onion plant Application of fertilize by cooked tea leaves, were significantly better in of the studied characters (plants height and Leaves Area) with rate increased to 47.15% and 93.4% respectively, than control treatment. Followed by T1 and then T3. Peanut Peels treatment gave the largest number of tubular blades in the plant (12.33), the diameter of the bulb neck (13.48mm) and bulb Length (7.35cm) than other treatments. Followed by T2 and then T3. Cooked tea leaves plants gave highest diameter of bulb (5.42cm), highest bulb weight (66g) and yield (20.85 t/ha) in the season. Where Achieving with T1 (18.35t/ha) significantly increase in the yield total in comparison with other treatments.
