Effect of NPS Fertilizers Application and Irrigation System on Growth and Yield of Snap Bean (Phaseolus vulgaris l): A Review

Abstract

Snap bean (Phaseolus vulgaris L.) is the most important vegetable crop for export and local market. Even though snap bean is many important, the yield haven been obtained is low mainly due to decline soil fertility and irrigation system problems. Now a day’s Ethiopian soils not only limiting phosphorus and nitrogen nutrients, but also sulfur is a major problem. Water stress that reduced yield and pod quality of snap bean. Irrigation schedule is very crucial to make the most efficient use of irrigation system to avoid excessive water and shortage problem. Snap bean required high amount of nitrogen fertilizer, due to its weak fixation capacity of atmospheric nitrogen. Application of nitrogen at 150 kg N ha^-1 increased growth and pod yield parameters snap bean. The optimum rate of phosphorus at 21 kg P ha^-1 was applied at the time of seeding in the form of triple super phosphate for snap bean production in Ethiopia. Application of sulfur at 30 kg S ha^-1 increased nitrogen, phosphorus and sulfur nutrient availability. Today there is lack of information on snap bean production in Ethiopia, especially NPS fertilizers application and under different irrigation system. Snap bean producers needs optimum rate of NPS fertilizers application and with different irrigation system, so research institutions and higher learning educations generate information to snap bean producers in Ethiopia at site-specific.
