Abstract
Lack of improved varieties and soil fertility degradation are among the major factors that limit durum wheat ( Triticum turgidum L.) production in Ethiopia. The objectives of this study were to determine the response of durum wheat cultivars (i) to nitrogen, phosphorus, sulphur, and boron (NPSB) fertilizer blend; (ii) rust infection; and (iii) partial budget analysis using NPSB fertilizer blend. A 2-location experiment was conducted in 2021 in South Ethiopia to evaluate the response of 4 durum wheat genotypes to blended NPSB fertilizer rates in a randomized complete block design in a 4 × 4 factorial arrangement. The results showed significant (P<0.05) differences due to genotypes (G), rate of NPSB fertilizer (F), and location (E) for all the parameters. The effects due to the G × F × E interaction were significant (P<0.05) for the number of total tillers, number of productive tillers, and grain yield (GY). A significant (P<0.05) G × E interaction was observed for the majority of parameters except days to 50% heading and plant height. Durum wheat genotype S 3 -213037 produced the highest grain yield of 3689.3 kg·ha −1 when NPSB fertilizer was applied at a rate of 225 kg·ha −1 at Adekoysha. Moreover, partial budget analysis indicated that genotype S 3 -213037 accrued a maximum benefit of 112,986.50 birr·ha −1 and the highest marginal rate of return of 1356.4% when NPSB fertilizer was applied at a rate of 225 kg·ha −1 . Therefore, this study indicated that the application of an NPSB fertilizer rate of 225 kg·ha −1 could be used in the production of durum wheat in the East African region with similar agroecologies to the study area.
