Item GROWTH AND YIELD RESPONSE OF COMMON BEAN (Phaseolus vulgaris L.) VARIETIES TO NPSB BLENDED FERTILIZER RATES AT EZHA DISTRICT, SOUTHERN ETHIOPIA(WOLKITE UNIVERSITY, 2022-04) DESALEGN KEBEDE ADEBAThe current average yield of common beans is far less than the national attainable yield in the study area. This is partially due to low soil fertility management and a lack of improved varieties. A field experiment was conducted to evaluate the effect of blended NPSB rates on yield and yield components of common bean varieties, to determine the optimum rate of blended NPSB fertilizer required and the best variety for optimum growth and yield of common bean, and to investigate economically feasible rates of blended NPSB fertilizer for common bean production. The experiment was conducted at Ezha district during 2022 cropping seasons. Treatments consisted of factorial combinations of four common bean varieties (Sab632, Ser119, Ser125, and Bz2) with four NPSB fertilizer rates (0, 50, 100, and 150 kg ha-1) laid out in a randomized complete block design with three replications. Data was collected on growth and yield and yield components and analyzed using SAS (version 9.3). The result showed that NPSB blended fertilizer rate and varieties significantly influenced most of the tested parameters of common bean. The highest days to flowering (51.0), nodule dry weight (3.106), number of pods per plant (17.60), above ground dry biomass (6131.7 kg ha-1), and grain yield (2862.7 kg ha-1) were recorded due to the application of 150 kg of NPSB ha-1 for variety Ser119. The highest days to maturity (99.33) and plant height (83.73cm) were recorded from variety Ser125 with a 150 kg NPSB fertilizer application rate. The maximum number of total nodules (73.67), effective nodules (43.55) and the highest harvest index (48.89%) were recorded from variety Ser119 with a 100 kg ha-1 NPSB fertilizer application rate. With a 150 kg ha-1 NPSB fertilizer application rate, variety Sab632 produced the highest hundred seed weight (42.30). The highest number of seeds per pod (3.76) was recorded from variety Ser125. Net benefit of 81,123.3 birr ha-1 was obtained from the treatment combination of 100 kg NPSB ha-1 application rate for variety Ser119. Thus, based on the study results, the application of 100 kg NPSB ha-1 with variety Ser119 could be recommended to enhance the productivity with the highest net benefits of common bean in the study area. The experiment was done only xii at one location and one season therefore it would have to be replicated across location and season to get best conclusive result and sound full recommendation for specific area in order to assure finding of the current study.Item TheCaseofHidaseYewogerawoGeneralSecondarySchoolinMihurnaAklil WoredaofGurageZone;CenteralRegionalSt ateofEthiopi(WOLKITE UNIVERSITY, 2024-08) ErmiasDeaBramoLack of adequate information on the use of Rhizobium strain and nitrogen-phosphorus-sulfur boron (NPSB) fertilizer rates are the major yield limiting factors for producing mung bean in the study area. Therefore, the study was conducted with the objective of evaluating the nodulation, growth and yield responses of two varieties of mung bean (Vigna radiate (L.) Wilczek) at differ ent rates of NPSB fertilizer and Rhizobium inoculates. A field experiment was carried out during the main cropping season of 2021/22 at Misirak Meskan District in Farmers Training Center (FTC). The treatments combinations were two levels of Rhizobium inoculation (with and with out), two mung bean varieties N-26 (Rassa) and NVL-1(Nassa) and four levels of NPSB fertilizer (0, 50, 100, 150 kg ha-1). The experiment was arranged in a 2×2×4 factorial combination in randomized complete block design with three replications. Soil samples were collected from the experimental field at (0-30cm depth) before planting and after harvest to determine selected soil physicochemical properties. Data on growth, nodulation, yield and yield components were rec orded and subjected to Analysis of Variance (ANOVA). Results on soil physicochemical proper ties analyzed before planting and after harvest showed significant differences due to the com bined effects of NPSB fertilizers and Rhizobium inoculation. Crop phenology (days to 50% flow ering and days to physiological maturity), growth (plant height, number of primary and second ary branches, shoot fresh and dry weight, root dry weight), and nodulation (number of nodules, nodule fresh and dry) weight of mung bean varieties were significantly affected by NPSB fertiliz er rates and Rhizobium inoculation. Moreover, the interaction effects of NPSB fertilizer rates, Rhizobium inoculation and mung bean varieties showed significant effects on number of pods per plant, number of seeds per pod, a hundred seed weight, harvest index, grain yield and above ground biomass. The highest mean value of grain yield(2105.77 kg ha-1) was obtained from a combined effect of 150 kg NPSB ha-1 and Rhizobium inoculation from variety N-26 which result ed in 61.28% followed by (2078.90 kg ha-1) which was increased by 62.07% at the rate of 100 kg NPSB ha-1 increase over the control (1290.37 kg ha-1). Furthermore, the number of seeds per plant, a hundred seeds weight, above ground dry biomass and HI of mung bean were recorded the highest mean values (607.33), (7.50 g), (4241.67 kg ha-1) and 0.483, respectively at the rate of 150 kg NPSB ha-1 fertilizer with a Rhizobium inoculation. The partial budget analysis re vealed that the maximum (ETB 108600.6 ha-1) net benefit was obtained from combined application of rhizobium inoculation and 100 kg NPSB ha-1from variety N-26 with MRR of 10130% And minimum (ETB 68572.8 ha-1) net benefit was obtained from the control. A net benefit ad vantage of 63.14% (ETB 68572.8 ha-1) when compared with the maximum and minimum net benefit. Hence, Rhizobium inoculation with application of 100 kg NPSB ha-1 could be tentatively recommended for mung bean production in Misirak Meskan area. However, the experiment should be repeated over years and locations to provide valid recommendations appropriate for the study site.
