Review on: Effect of different nitrogen rate on the growth and yield of cabbage (Brassica oleracea var L.)
Mekonnen Gebeyaw and Salew Belete
Cabbage (Brassica oleracea var L.) is also known as cool vegetable crops. It is one of the most popular and widely growth vegetable crops in the world. It contains a range of essential vitamins and minerals as well as small amount of protein and good caloric value. Cabbage is an excellent source of mineral such as calcium, iron, sodium, Potassium and phosphorus. In our country has a variety of vegetable crops grown in different agro-ecological zones by small farmers, mainly as a source of income and food. Cabbage can be grown at any time of the year but better quality and greater yields can be obtained during warmer months of the year. Cabbage has been domesticated and used for human consumption since the earliest antiquity. It is only head cabbage that changes in leaf shape becoming wider because of the shorter petiole length with increasing leaf position and thus cabbage acquired the developmental change in leaves. Nitrogen is a constituent of all living things a synthesis and transfer of energy. Nitrogen rate has a significant effect on leaf length of cabbage. Similarly leaf width of cabbage had significant difference between different rates of nitrogen. Nitrogen is vital for the leaf growth of cabbages to begin.
