– Soil fertility decline is one of the principal factors contributing to low productivity of crops and food insecurity in Ethiopia. The information available with regards to effect of blended fertilizer type and rates on growth and yield performance of bread wheat ( Triticum aestivum L.) for optimum production on loam soils of Wondo district is very limited. Therefore, a field experiment was conducted on loam soils of Wondo district Bachel Gigissa Peasant Association Farmers training center during 2018 cropping season to assess the effect of different blended fertilizer types and rates on growth, yield and yield components of bread wheat. The treatments studied consist of: control and three blended fertilizer formula NPS, NPSB, and NPSBZn each with four different rates (50, 100, 150 and 200 kg ha 1 ). Recommended rate of Urea (100 kg ha -1 ) was used equally for all treatments in spilt application and Danda’a variety was used as a test crop. The treatments were laid out in a Randomized Complete Block Design with three replications. Soil and crop data were collected and analyzed using the SAS statistical package program version 9.4 and LSD at 5% probability level was used to establish the difference among the means. The soil result revealed that the experimental soil site texture was classified as loam. The highest (30.06 kg -1 ) agronomic efficiency obtained from150 kg ha -1 NPSB. The results revealed that application of blended fertilizers (NPS, NPSB and NPSBZn) delayed days to flowering, and physiological maturity by (13, 9, 10) and (15, 14 and 11) days, respectively as compared to control plot. Leaf Area Index and Straw yield were significantly (p ≤ 0.01) affected by the application of different blended fertilizer rates and significantly (p ≤ 0.05) by the main effect of blended fertilizer types and interaction effect. Grains per spike and grain yield were significantly (p ≤ 0.01) affected due to the main effects of blended fertilizer types and rates, they were also significantly (p ≤ 0.05) affected due to the interaction effect. Above ground biomass was significantly (p ≤ 0.01) affected due to main effect of blended fertilizer rates and the interaction effect however, non-significant (p > 0.05) due to blended fertilizer types. This study also revealed that, blended fertilizer types and rates significantly (p≤0.05) affected DH, NFTm -2 , DPM, PH, SL and HI while TSW was significantly (p≤0.05) affected only by the main effect of blended fertilizer rates. Blended fertilizers had improved Agronomic nutrient use efficiency of wheat as compared to the control treatment. The highest (6.17t ha -1 ) grain yield was obtained from 200 kg ha -1 NPSB +100 kg ha -1 urea application followed by (6.11 t ha -1 ) from 150 kg ha -1 NPSB + 100 kg ha -1 urea, while minimum (1.95t ha -1 ) grain yield was attained from the control treatment. However, the application of 150 kg ha -1 NPSB + 100 kg ha -1 urea had highest marginal rate of return (MRR %) and Net benefit.
-土壤肥力下降是造成埃塞俄比亚作物生产力低下和粮食不安全的主要因素之一。关于混合肥料类型和用量对圆岛地区壤土上面包小麦生长和产量性能的影响，以实现最佳生产的资料非常有限。因此，本研究于2018年种植季在Wondo地区Bachel Gigissa农民协会农民培训中心的壤土上进行了田间试验，评估不同混合肥料类型和用量对面包小麦生长、产量和产量构成的影响。所研究的处理包括:对照和3种混合肥料配方NPS、NPSB和NPSBZn，每种配方分别施用50、100、150和200 kg / h1。各处理均匀施用尿素推荐用量(100 kg ha -1)，以丹达a品种为试验作物。治疗采用随机完全区组设计，有3个重复。土壤和作物数据的收集和分析使用SAS统计软件包程序9.4版，并采用5%概率水平的LSD来确定均值之间的差异。结果表明，试验场地土壤质地为壤土。150 kg ha -1 NPSB的农艺效率最高(30.06 kg -1)。结果表明，与对照区相比，施用NPS、NPSB和NPSBZn混合肥料分别延迟了(13、9、10)天和(15、14和11)d的开花和生理成熟期。不同混肥用量对叶面积指数和秸秆产量的影响极显著(p≤0.01)，对混肥类型主效应和互作效应的影响极显著(p≤0.05)。单穗粒数和单穗产量受混合肥料类型和用量的主要影响极显著(p≤0.01)，互作效应对单穗粒数和单穗产量也有显著影响(p≤0.05)。混合肥料的主效应和互作效应对地上生物量影响显著(p≤0.01)，混合肥料类型对地上生物量影响不显著(p > 0.05)。本研究还发现，混合肥料类型和配比显著(p≤0.05)影响DH、NFTm -2、DPM、PH、SL和HI，而TSW仅受混合肥料配比的主效应显著(p≤0.05)影响。与对照处理相比，混合施肥提高了小麦的农艺养分利用效率。200 kg ha -1 NPSB +100 kg ha -1尿素处理的产量最高(6.17t ha -1)，其次是150 kg ha -1 NPSB +100 kg ha -1尿素处理(6.11 t ha -1)，而对照处理的产量最低(1.95t ha -1)。150 kg ha -1 NPSB + 100 kg ha -1尿素的边际报酬率和净效益最高。因此，Wondo地区小麦宜采用150 kg ha -1 NPSB + 100 kg ha -1混肥。此外，基于产量、净效益和相对较低的生产总成本，Wondo地区的农民也可以使用100 kg ha -1 NPSB+ 100 kg ha -1尿素。然而，由于实验只在一个季节和一个地点进行，为了得出合理的建议，在不同的地点和同一实验地点重复试验是很重要的。
