| Abstract | ||||
| This experiment was conducted in the private farm in Hadhramout valley, Seiyun Hadramout governorate, within the period of season 2008/2009 - 2009/2010. The objective of the experiment was to the study of effect of farmyard Manure (FYM) 5t/ fed, fish-meal 5t/ fed, and mineral fertilizer(100kg urea+50kg triplesuperphosphatc/ fed.) fertilizer with or without foliar application with micronutrients, on bulb yield Baftaim Onion cultivar. Eleven treatments were exploited at a randomized complete block design with three replications. The application of fertilizers significantly increased diameter and height of onion bulb. The highest increment in diameter and height of bulb (15,14,2 %) were recorded with FYM, and mineral fertilizer In the first season (11.8,17.3 %) were recorded with mineral fertilizer, and FYM in the second season. The results indicated that onion bulb weight, yield/feddan. Increased significantly with fertilizers application. The highest rate of increase in bulb weight (24.2 and 50.5%) were recorded with FYM, followed by mineral fertilizer (48.8 and 19.3%) in the two years, respectively. The application of fertilizer significantly increased yield bulb/ feddan. The highest increment of yield (57.1 and 44.6%) were recorded with mineral fertilizer while the increment in yield of bulb (44.7, 27.7 , 27.6, 28.4, 22.4 and 22.1 %) were recorded with mineral fertilizer+ FYM , mineral fertilizer + fish-meal fertilizer, and FYM. within the seasons, respectively. The addition of 5g/L micronite decreased all the measured characters for all treatments where foliar application was used. Compared with the treatments without using foliar application. The use of organic for onion production can be recommended to reduce mineral fertilizer without reducing the productivity This won save the high cost of chemical fertilizer as well as well as to decrease pollution.
