Abstract
Shortage of improved varieties and soil nutrient depletion are the major production constraints of fenugreek in mid-altitude of Bale Zone in Ethiopia. Therefore, an on-farm experiment was conducted at Ginir, south-eastern Ethiopia, to assess the effect of NPS fertilizer rates on growth and, yield components and seed yield of fenugreek varieties. Factorial combinations of three fenugreek varieties (Burqa, Chala and Ebisa) and five rates of NPS (0, 50, 100, 150 and 200 kg NPS ha-1) were laid out in a randomized complete block design (RCBD) with three replications. Analysis of variance showed that the main effects of varieties significantly influenced days to 50% flowering, days to 90% physiological maturity and thousand seed weight. The highest thousand seed weight (17.31 g) was recorded from variety Burqa. Variety Chala was the earliest to reach days to 50% flowering (63.27 days) while variety Burqa was the earliest (115 days) to reach 90% of physiological maturity. Similarly, the main effect of NPS showed significantly higher number of primary branches per plant (5.11), number of pod per plant (25.47) and biomass yield (7160 kg ha-1) at 200 kg NPS ha-1 while the highest thousand seed weight (18.44g) was obtained at 150 kg NPS ha-1. The interaction of NPS fertilizer and varieties showed significant effect on plant height, number of seeds per pod and seed yield. The highest plant height (53.67cm) was recorded from Chala variety at 200 kg NPS fertilizer ha-1 while the highest number of seeds per pod (11.89) was recorded from variety Burqa at 150 kg NPS fertilizer ha-1. Similarly, the highest seed yield (1980 kg ha-1) was recorded from variety Ebisa at 150 kg NPS fertilizer ha-1. The economic analysis revealed that the highest net return of (42231.67 and 40361.9 ETB ha-1) with marginal rate of return (566.84 and 542.5%) were recorded for varieties of Ebisa and Chala respectively, while variety Burqa resulted in the higher net benefit (39294.8 ETB ha-1) with the highest marginal rate of return (166.24%) at 100 kg NPS ha-1. Therefore, it can tentatively be concluded that application of 150 kg NPS ha-1 Ebisa and Chala varieties and 100 kg NPS ha-1 of variety Burqa to be the best treatment in the study area.
改良品种短缺和土壤养分枯竭是制约埃塞俄比亚贝尔地区中海拔胡芦巴生产的主要因素。因此,在埃塞俄比亚东南部的Ginir进行了一项田间试验,以评估NPS施肥量对葫芦巴品种生长、产量组成和种子产量的影响。3个胡芦巴品种(Burqa、Chala和eisa)和5个NPS(0、50、100、150和200 kg NPS ha-1)的因子组合采用随机完全区组设计(RCBD),设3个重复。方差分析表明,品种主效应显著影响开花天数~ 50%、生理成熟度天数~ 90%和千粒重。布卡品种千粒重最高,达17.31 g。品种“查拉”(63.27 d)和品种“布卡”(115 d)最早达到生理成熟的90%。同样,在200 kg NPS ha-1处理下,单株一次枝数(5.11个)、单株荚果数(25.47个)和生物量产量(7160 kg ha-1)显著增加,而在150 kg NPS ha-1处理下,千粒重(18.44g)最高。氮磷肥与品种互作对种子株高、单荚粒数和产量均有显著影响。Chala品种在200 kg NPS hm -1处理下最高株高(53.67cm), Burqa品种在150 kg NPS hm -1处理下最高每荚种子数(11.89)。同样,品种e比萨在150公斤NPS肥每公顷时的种子产量最高(1980公斤每公顷)。经济分析结果表明,在100 kg NPS hm -1处理下,艾比沙和查拉品种的净收益最高,分别为42231.67和40361.9 ETB ha-1,边际收益率分别为566.84和542.5%;布卡品种的净收益最高,为39294.8 ETB ha-1,边际收益率最高,为166.24%。因此,可以初步得出,在研究区施用150 kg NPS ha-1 eisa和Chala品种和100 kg NPS ha-1 Burqa品种为最佳处理。
