Abstract

In the semi-arid regions of Ethiopia, water is the most limiting factor for crop production. Meeting crop water demand maximizes productivity from a land unit but does not inherently increase revenue per unit of water. This has led to a growing interest in irrigation practices that improve water productivity by regulating the inappropriate use of irrigation water. The experiment was conducted in the Woleh irrigation Scheme, to verify the efficiency of alternative furrow irrigation on onion water productivity and yield. The treatments used a randomized complete block design with four replications. Alternating furrow irrigation (AFI), conventional furrow irrigation (CFI), and fixed furrow irrigation (FFI). Each method used 75% ETc of the irrigation water. The experiment showed that AFI had the highest yield and water productivity. The amount of irrigation water used for AFI and FFI was about half (3038 m3) of CFI (6078 m3). The water productivity obtained was 4.05 kg m-3 for AFI and 3.16 kg m-3 for FFI, almost double the 2.15 kg m-3 for CFI. Economic water productivity and marginal rate of return were greatest in AFI. Therefore AFI at 75% ETc was superior in yield and water productivity in areas with water scarcity and high labor costs.

Abstract

Depleting soil nutrients is among the significant factors affecting production and productivity in Ethiopia. From the nutrients, nitrogen is the most yield-limiting, which governs wheat production. Therefore, the study was conducted to examine the effect of nitrogen on the yield and yield components of bread wheat varieties. The experiment was implemented in the 2019 and 2020 cropping seasons at Sekota and Lasta districts on the farmers’ field. The treatments consisted of a factorial combination of four levels of nitrogen (0, 46, 69, and 92 kg ha-1) and two varieties of wheat (Sekota-1 and Hibst), which were replicated three times in a randomized complete block design. Each treatment was provided with 23 kg ha-1 triple supper phosphate (P2O5). The study’s results indicated that grain and yield-related traits were significantly affected by nitrogen application. The increasing rate of nitrogen up to 92 and 69 kg ha-1 increases wheat grain and biomass yield by (150.3% and 54.1%) and (95.9 and 60%) in Sekota and Lasta districts, respectively. The highest grain yield (2562 and 2980 kg ha-1) was obtained from applying 92 and 69 kg ha-1 N at Sekota and Lasta, respectively. Therefore, applying 92 and 69 kg ha-1 N is the appropriate rate and recommended for the Sekota and Lasta districts, respectively.
