abstract
Potato is one of the most crucial food vegetation worldwide, and ranks 1/3 after rice and wheat in terms of human consumption. It is has been indicated, potato tubers are the subterranean swollen, starchy tubers of the potato plant and are of utmost popularity as staple food for thousands of tens of millions of humans in the world. Nitrogen performs critical function in all dwelling tissue of the plant. No different factors have such an effect on merchandising vigorous plant growth. Abundant of protein tends to increase the measurement of the leaves accordingly, to carry about an increase in carbohydrate synthesis. According to specific literature reviews the production of potato is constrained via specific factors, among these, insufficient application of nitrogen fertilizers is outstanding one. Hence farmers produce potato for meals crop rain fed conditions. However, there is no a complete suggestion for Nitrogen fertilizers. Hence, information is missing on the gold standard nitrogen fertilizer rates. Nitrogen fertilizer supply and rate notably interacted in all vegetative growth traits as expressed by using plant length, leaf number/plant, leaf area/plant, leaf chlorophyll content, and plant clean and dry weights. Nitrogen rate will increase the total tuber number, marketable whole number, complete tuber yield, marketable tuber yield and average tuber weight with growing nitrogen utility rate. The growing in quantity of marketable with increasing in application nitrogen is related with reduce in the range of small dimension tubers due to extend in the weight of character tubers.
