    EFFECT OF INTER ROW SPACING AND VARIETIES ON GROWTH AND YIELD OF FENUGREEK (Trigonella foenum-graecum L.) AT WOLISO DISTRICT, SOUTH WEST SHOA ZONE, ETHIOPIA
    (WOLKITE UNIVERSITY, 2024-05) LETA ABEBE BEDADA
    Fenugreek (Trigonella- foenum-graecum L.) is a legume crop which is used as a spice, vegetable, animal feed and medicinal plant. Inter row spacing is one of the yield limiting factors on fenugreek production. A field experiment was conducted at Woliso Polytechnic College during the 2023/2024 cropping season. To evaluate and determine the combined effect of inter-row spacing (10cm, 20cm, 30cm and 40cm) and varieties (Burqa, Chala, Ebbisa, Wereilu and one local variety for check) on yield and yield components fenugreek. The experiment was laid out under Randomized Complete Block Design with Factorial arrangement and three replications. Based on the data analysis, the higher yield and yield components were recorded from planting of fenugreek with the wider inter-row spacing of 40cm. The shortest days for 50% flowering (44.6 days), the shortest days for 90% maturity(117.9), the highest number of primary branches (6.73), the highest number of pods per plant-1(29.33), the highest number of seeds per pod-1(21.6), the highest pod length(19.3), the highest 1000g seed weight (20.6), the highest above ground biomass (3568.33Kg ha-1), the highest harvesting index (40.2% and the highest seed yield (1586) were recorded from the 40cm inter-row spacing followed by 30cm. On the other hand, the lowest yield(324.66 kg ha-1) and yield attributes were recorded when the crop was grown under the smallest inter-row spacing of 10cm. The higher number of primary branches, number of seeds pod-1(21), pod length (19.3), 1000g seed weight (20g) and seed yield (1586 kg ha-1) were recorded from Burka inter acted with 40cm followed by Chala, Wereilu, and Ebbisa verities whereas the lower grain yield and yield component was recorded from with the interaction of 10cm. From the current research-based yield and yield component planting of Burka variety with 40 cm inter row spacing is performing well and recommended to the local farmer to increase the yield of fenugreek crop.

    RESPONSE OF POTATO (Solanum tuberosum L.) VARIETIES TO BLENDED NPSB FERTILIZER ON GROWTH, YIELD AND QUALITY PARAMETERS AT GUMMER DISTRICT, SOUTHERN ETHIOPIA
    (WOLKITE UNIVERSITY, 2022-03) DAMTEW GIRMA LEGESE
    Potato is an important food security and cash crop in Southern Ethiopia including Gurage Zone. However, productivity of the crop in the zone is far below its potential due to an array of factors. For instance, inappropriate selection of varieties and lacking information regarding the actual rate of the newly recommended blended NPSB fertilizer in the potato producing areas including Gummer district. Cognizant of this, the present experiment was initiated and conducted in Gummer district under supplementary irrigation, during the 2021 Belg season, with the objective of assessing the response of different potato varieties to blended NPSB fertilizer rates. The experiment was laid out in Randomized Complete Block Design (RCBD) with factorial arrangement and having three replications. There were 12 treatment combinations, which comprised of three potato varieties (namely; Belete, Gudanie and a local check, Askot) and fourrates of blended NPSB fertilizer rates (0, 119,238 and 357 kg NPSB ha-1). The analysis of variance showed that the two main factors (blended NPSB fertilizer rates and potato varieties) had a statistically significant effect on all tested parameters except the effect of the blended NPSB fertilizer rates on days to 50% emergence. The interaction of the two factors had also showed a statistically significant effect on days to 90% maturity, plant height, main stem number per plant, total tuber number/hill, tuber yield per hill, large sized tuber yield, marketable and total tuber yields (t ha-1) and tuber dry matter content. Days to 90%maturity were delayed with increased rates of blended NPSB fertilizer for all tested varieties. The highest mean plant height (69.54cm) and number of main stems per hill (8.38) were obtained at 357 kg ha-1NPSB with Belete variety. The highest marketable tuber yield (34.40 t ha-1), total tuber yield (35.84 t ha-1) and tuber dry matter content of (26.75%) were obtained from Belete variety with the application of 238 kg ha-1 NPSB fertilizer. The results of the economic analysis indicated that the maximum net benefit (180660.7 Birr ha-1) with 3405.23% marginal rate of return was obtained from Belete variety with the application of238 kg NPSB ha-1Hence, the application of 238 kg ha-1 with Belete variety can be recommended or optimum potato production with the acceptable economic benefit in the study area and similar agro-ecology. However, since the result is only of one season and location, further research is recommended to be carried out across more seasons and locations.
