“…On the other hand, the decrease in grain yield associated with NPSB fertilizer rates beyond 125 kg•ha −1 may be attributed to an increased nitrogen rate, which promotes excessive vegetative growth in crop plants, consequently reducing the grain yield of common beans. Tis fnding aligns with previous studies by Arega and Mekonnen [42], Deresa [43], Tirfessa et al [45], Zewide et al [46], and Dela et al [48], which suggested that the increase in grain yield with the application of blended inorganic fertilizer could be attributed to the sufcient supply of N, P, S, and B soil solutions for crop uptake. Tis leads to an increase in the number of branches per plant and, subsequently, an increased photosynthetic area, resulting in more pods per plant and a higher number of seeds per pod.…”

“…In Deneba, increasing the NPSB fertilizer rate from 0 to 125 kg•ha −1 , and in Wara, increasing it from 0 to 175 kg•ha −1 , signifcantly increased the number of seeds per pod, with a subsequent decrease observed after reaching the maximum fertilizer rate. Previous studies by Tadesse et al [44], Tirfessa et al [45], and Zewide et al [46] reported similar fndings, where varying NPSB fertilizer rates (100-150 kg•ha −1 ) resulted in the highest number of pods per plant and seeds per pod. Tese studies highlight the importance of considering geographical location and soil type when determining optimal fertilizer rates.…”

Soil fertility decline is a significant factor affecting crop production. In a specific area, fertilizer application for a crop depends on soil type and profitability. Moreover, optimizing chemical fertilizer utilization in crop production is crucial from both environmental and economic perspectives. However, there is limited information available on the optimum NPSB fertilizer rate for common bean production in the study area. Thus, the study aimed to establish area-specific NPSB fertilizer rate recommendations for optimal grain yield and profitability of common bean. The field experiment was conducted in two locations in the 2019 and 2020 cropping seasons. The treatments included 0, 25, 50, 75, 100, 125, 150, 175, and 200 kg·ha−1 NPSB fertilizer rates, and they were planted using a randomized complete block design with three replications. The combined location analysis of variance indicated that the application of NPSB fertilizer significantly influenced plant height, number of pods per plant, number of seeds per pod, hundred-seed weight, biomass yield, grain yield, and harvest index. The highest grain yields (2815 kg·ha−1 and 3433 kg·ha−1) were recorded with the application of a 125 kg·ha−1 NPSB blended fertilizer rate, while the lowest grain yields (1429 kg·ha−1 and 1500 kg·ha−1) were produced from the nonfertilizer applied plot in Deneba and Wara, respectively. The combined location mean showed that the maximum grain yield (3124 kg·ha−1), followed by 2710 kg·ha−1, was produced by the application of 125 and 100 kg·ha−1 NPSB fertilizer rates, respectively. The data indicate that raising the NPSB fertilizer rate from 0 to 125 kg·ha−1 would greatly boost grain yield in the common bean in both locations in a similar manner. The economic analysis revealed that applying 125 kg·ha−1 of NPSB fertilizer earned the highest net benefits (140453.2 ETB·ha−1) with the highest marginal rate of return (1745.26%). Therefore, for high yield and profitability of common bean, a rate of 125 kg·ha−1 NPSB fertilizer is suggested in the study area and similar agro-ecological zones.

“…This might be because indeterminate varieties produce additional nodes after initial flowering as a result, the physiological maturity becomes longer and their genetic differences influence the phenological periods of the field pea varieties. In conformity to these results Argaw and Mnalku 4 and Tirfessa and Lamessa 17 , reported significant differences in the number of days to reach 50% flowering and days to reach physiological maturity among common bean varieties in Ethiopia.…”

Background and Objective:The low attention of smallholders and low soil fertility are the main reasons for the low productivity of field peas in Western Ethiopia. Thus, a study was conducted to investigate the effects of Rhizobium inoculation and NPS fertilizer rates on nodulation, yield and yield components of field peas and to identify economically profitable treatments that can maximize the productivity of field peas in the study area. Materials and Methods: Two levels of Rhizobium inoculation (No inoculation and EAL301), two field pea varieties (Jidha and Lammiif) and five rates of NPS fertilizer (0, 25, 50, 75, 100 kg NPS haG 1 ) were arranged in Randomized Complete Block Design (RCBD) with three replications and all collected yield and yield related parameters were analyzed using R statistical software. Results: Phenological and growth parameters were influenced by the main effects of varieties whereas harvest index was influenced by varieties and NPS fertilizer rates. On the other hand, pod numbers per plant and seed yield were significantly affected by the three-way interaction of Rhizobium, varieties and NPS fertilizer rates. The highest grain yield (2800 kg haG 1 ) was obtained from the application of 100 kg NPS haG 1 +Rhizobium inoculation which was followed the by application of 100 kg NPS haG 1 for the lammiif variety. The highest net benefit (93490 and 82290 Birr haG 1 ) and MRR (1596.0 and 1593.3%) were recorded from the application of 100 and 100 kg NPS haG 1 +EAL301 strain. Conclusion: Thus, the application of 100 kg NPS haG 1 only or the application of 100 kg NPS haG 1 +EAL301 strain inoculation is recommended for field pea production in western highlands of Oromia and similar agro-ecologies.

“…In summary, the gains in dry matter and yield promoted by the use of PSB are similar to those promoted by the use of phosphate fertilizer, associated with the P supply by either chemical or biological fertilization. The gains promoted by the treatments are due to the function performed by P in plants, especially legumes, stimulating nodulation and biological N fixation [47]. As these are important parameters for the final yield, the common bean responded with maximum yield of 3489 kg ha −1 when inoculated with a PSB dose of 159 mL ha −1 (Figure 8D).…”

The use of phosphate-solubilizing bacteria (PSB) can be a sustainable strategy to increase phosphorus availability and promote satisfactory crop yields. The objective of this study was to evaluate whether inoculation with PSB in common bean increases (i) growth, (ii) nutrition, (iii) yield, and (iv) grain quality, and (v) reduces the chemical phosphorus application dose to obtain maximum yields. The experiment was conducted in an Oxisol using a randomized block design in a 4 × 4 factorial scheme, with four replicates, using the cultivar IAC 2051. The first factor was four doses of P2O5 (0, 20, 40 and 60 kg ha−1), and the second factor was four doses of PSB (0, 100, 200 and 300 mL ha−1). For leaf area and leaf chlorophyll content, the association of PSB inoculation with a P2O5 dose of 40 kg ha−1 promoted the best conditions for the common bean. P2O5 application increased yield by 79 kg ha−1 for each 10 kg ha−1 added. PSB inoculation at a dose of 192 mL ha−1 promoted P export of 15.3 kg ha−1, and the PSB dose of 159 mL ha−1 increased yield by 389 kg ha−1 (12%) compared to the control. Grain quality remained within the standards required by the consumer market, being little affected by the treatments. Improvements in common bean growth and nutritional and physiological status promoted by P2O5 application and PSB were essential in increasing yield, so these are sustainable production strategies.
