Adapting onion cultivation to high-humidity regions

The overall aim of this study is to find a technique for adapting onion cultivation in a humid zone, in order to obtain higher yields, identify the most suitable species in the soil of the humid region, and determine the germination rate and growth of each species. To achieve these objectives, several materials and methods were used. Experimental results show that of the threeAllium cepa varieties, red onions germinate first; yellow onions have the lowest germination rate, while red onions have the highest;vegetative growth of the plant: yellow onions and red creoles grow a little slowly, red onions the fastest; red onions have the heaviest bulb and yellow onions the lightest; red onions have the largest bulb and red onions the highest yield in kg/ha, ranging from 290 to 300kg/ha. The problem with this crop is bulb rot: yellow onions have the highest rate of rot.
