Yield and Yield Components of Snap Bean (Phaseolus vulgaris L.) as affected by N and P Fertilizer Rates at Jimma, Southwestern Ethiopia

Field experiments were conducted at Adami Tulu, Ethiopia, for two successive dry seasons to investigate how nitrogen levels and deficit irrigation affect the yield and its related components, and the protein content of snap beans. The treatments were deficit irrigation with three levels (50, 75, and 100% ETc) and application of nitrogen with four levels (0, 46, 92, and 138 kg·N·ha−1), which were set up as split-plot arrangement, with irrigation being as the main plot and nitrogen levels as subplot, replicated thrice. Results showed that the pod yield had a substantial impact ( p < 0.01 ) on the interaction between the two factors; i.e., interaction of 100% ETc and 92 kg nitrogen levels per hectare recorded the highest pod yield (22.69 t·ha−1), but treatment combinations of 50% ETc and no nitrogen application produced the lowest amount of overall pod yield (6.922 tons per hectare). However, the results showed that the application of 75% ETc in combination with 92 kg nitrogen per hectare recorded the highest protein concentration (17.718%) but statistically equivalent to 138 kg nitrogen per hectare combined with the same deficit irrigation level, while the lowest protein concentration (12.24%) was recorded at 50 ETc combined with no fertilizer. Hence, the use of 75% ETc along with 92 kg nitrogen levels per hectare could be optimal in balancing quality and pod output of green beans at Adami Tulu and surrounding areas.

“…These result is similar to Negash, et al, (2018) reported that applications of different rates of potassium fertilizer influence number of pods per plant. Similarly, Tantawy, et al, (2009) observed significantly increased number of pods per plant of common bean at application rate of 100 kg k 2 o/fed.…”

To investigate the effect of sowing dates and potassium fertilizer rates on seeds yield and yield component of lima bean. Two field experiments were conducted at Sakha Agricultural Research Station during 2015 and 2016 summer seasons. Four sowing dates (1 st May, 15 th May, 30 th May and 15 th June) and potassium fertilizer rates (0, 50, 75, and 100 kg/fed) were used as treatments. The main findings could be summarized as follows:Sowing dates significantly affected seed yield (t/fed), No. of seeds/pod, pod length (cm), No. of pods/plant, pods weight/plant, plant height (cm), stem diameter (cm), No. of branches/plant. Sowing on 1 st May significantly exceeded all studied traits compared with other sowing dates and produced the highest yield (2.477 t/fed), while the lowest sowing date on 15 th June. The stem diameter increased with sowing late (1.810 t/fed.).Potassium fertilizer rates significantly affected on seed yield (t/fed), No. of seeds/pod, pod length (cm) , No. of pods/plant, pods weight (t/ fed), plant height (cm), stem diameter (cm), No. of branches/ plant. The results indicated that the highest lima bean seed yield was 2.375 (t/fed) when fertilized with100kg k 2 o/fed and the lowest at control zero fertilizer 1.990 (t/fed).It could be concluded that early sowing on 1 st May with addition potassium fertilizer rate at 100 kg k 2 o/fed were the recommended treatment to produce the highest seed yield production of lima bean at North Delta under the environmental condition of Kafr EL-Sheikh Governorate.

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.
