Tef [Eragrostis tef (Zucc)] grain yield response to nitrogen fertilizer rates in East Badewacho district, Hadiya Zone, Southern Ethiopia

Abstract

Soil fertility depletion is the most important concern all over the world mainly in Sub-Saharan African. The principal one is N fertilizer and it is the most yield-limiting nutrients for crop growth, development as well as production. However, most farmers applied a limited N fertilizer rate for tef production. Hence, a study was to investigate the effects of four nitrogen fertilizer rates (0, 30, 60, and 90 kg N/ha −1 ), on the grain yield of tef. The study was carried out in a randomized complete block design with three replications in East Badewacho district at the farmers training center in the 2019 cropping season. All the relevant data were collected and then subjected to SAS software 9.4 and mean differences were compared using LSD at 5%. The effects of the N rate showed significant differences (P ≤ 0.05) for all parameters of tef studied. Application of N rate at 90 kg ha −1 was significantly (P ≤ 0.01) improved yield and yield components of tef. Furthermore, N rates increased the magnitudes of all the important yield attributes. Hence, it is tentatively thinkable to conclude that a further supply of N fertilizer rate advances yields components of crops. Thus,

Determination of the Appropriate Blended Inorganic Fertilizer Rate Recommendation for the Optimal Common Bean (Phaseolus vulgaris L.) Grain Yield and Profitability in the Dawuro Zone, Ethiopia

“…Sustaining soil fertility in sub-Saharan Africa, particularly in countries like Ethiopia experiencing rapid population growth, poses a signifcant challenge. With increasing pressure on agricultural land and the predominance of smallholder farming, ensuring adequate food production has become increasingly difcult [16,17]. A signifcant portion of the increase in food production can be attributed to the widespread use of inorganic fertilizers.…”

“…Because of this, smallholder farmers and scholars face diffculties in understanding the proper dosages of NPSB fertilizers for common bean production. Furthermore, the application of fertilizers should be tailored to the local climate, soil, and management practices to enhance crop production economically and sustainably [16,17,30,31]. Terefore, comprehension of the plant nutrient needs of a specifc area is crucial to increasing crop productivity and production on a sustainable basis.…”
