Evaluation of NPS Fertilizer on Yield and Economic Performance of New Variety of Hot Pepper (Capsicaim Annum) in Tanqua Abergelle, Central Tigray, Ethiopia

Abstract

Hot Pepper (Capsicum annum L.) is one of the major economically important horticultural crops in Tanqua-Abergelle district. However, its productivity is low mainly due to soil nutrient deficiency and using unappropriated rate of Fertilizer. NPS is one of the most deficient elements in the area. The experiments were designed to study the effect of NPS levels accompanied with one level of DAP as standard check (150, 200, 250kg/ha NPS and 200kg DAP/ha carried out in randomized complete block design (RCBD) with three replications. The analyzed result showed the growth yield and yield components of pepper (Capsicum annuum L) were observed from 2014 to 2016 under irrigation. NPS levels was significantly affected on pepper fruit number per plant, total yield and marketable yields. However, on fruit length, plant height and unmarketable yields are not revealed significance difference. The level of 200kg/ha NPS Significantly showed highest marketable yield 101.97qt/ha than the other treatments (150kg/ha NPS, 250 kg/ha NPS and 200 kg/ha of DAP. Based on the economic feasibility 200kg/ha of NPS fertilizer gives a significant marginal rate of return (3013.8%). Thus, level have best profitability advantage over the other treatments. Therefore, according the result (yield and MRR) the conclusion is using the 200kg/ha important to increase yields for the growers in the study area. Thus, to fill the pepper production constraints resulted from nutrient deficiencies such as nitrogen, phosphorus and sulfur fertilizer, further research on NPS combination levels, nutrient use efficiencies, nutrient uptake rate and nutrient recovery is crucial. Moreover, further research across locations and years deemed important to validate the current result of this research work.
