Abstract: Six Moringa stenopetala provenances (Abay Filklik, Arbaminch, Gofa, Wolayita, Konso and Babile) were examined for survival and growth parameters at Daro Lebu and Hawi Gudina districts since 2019. This study was undertaken with randomized complete block design with four replications. At age of three year; survival rate, tree height, diameter at breast height (DBH), root collar diameter, canopy diameter (CD) and fresh leaf biomass were assessed. The result indicated that at Daro Lebu, there were significance (P < 0.05) among provenances; in their survival rate, height, root collar diameter, and fresh leaf biomass, but DBH and canopy diameter did not show statistical difference. Survival rate showed significant difference between provenances at Daro Lebu; while at Hawi Gudina site there was no significant difference. Survival rate at Daro Lebu ranged from 50% for M.Gofa and M.wolayita while, M.babile was 83.33%. At Hawi Gudina site survival rate was 91.67% for M.abay Filiklik and 100% for M.konso, M.arbaminch and M.wolayita. All provenances in both sites except M.gofa, M.gofa and M.konso at Daro Lebu had survival rate above 66%. At Daro Lebu, M.abay Filiklik demonstrated superior mean height (2.53 m) followed by M.babile (2.09 m) and M.wolayita (1.2 m) is the shortest provenance. At Hawi Gudina site, M.arbami demonstrated superior mean height (2.32m) followed by M.konso (2.3 m) and M. babile (1.57 m) were the shortest provenance. M.gofa demonstrated superior RCD (99.17 mm) followed by M.babile (98 mm), while M.wolayita (61.09 mm) shown the lowest performance at Daro Lebu. While, at Hawi Gudina site site, M.arbaminch demonstrated superior RCD (138.67mm) followed by M.konso (135.42 mm); while M.babile (107.09 mm) shown the lowest performance. At Daro Lebu, M.babile demonstrated superior fresh leaf biomass (1.61 kg) followed by M.gofa (1.59), while M.wolayita (0.48 kg) shown the lowest performance. At Hawi Gudina site, M.gofa demonstrated superior fresh leaf biomass (3.11 kg) followed by Wolayita (2.91 kg), while M.babile (1.34 kg) shown the lowest performance. Owing to superior growth performances attained, M.babile, M.gofa and M.konso be recommended for Daro Lebu and similar agro-ecology, while M.arbaminch, M.gofa and M.konso for Hawi Gudina and similar agro-ecology.

Abstract: Hot pepper (Capsicum annuum L.) is one of the most important and economical vegetable crop produced in Ethiopia including Gurage zone. Use of appropriate plant spacing’s and optimum nitrogen application are the major agronomic practice to improve the productivity of hot pepper. However, the productivity of hot pepper is low its potential due to many factors such as poor soil fertility, under or above optimum plant population, inappropriate fertilizer application with blanket application in all soil type and crop varieties. Therefore, this experiment was conducted at Wolkite University, College of Agriculture and Natural Resource Demonstration site with the objectives of determining the optimum level of N fertilizer and intra-row spacing for better growth of hot pepper. The experiment consisted of three levels of nitrogen (N1 (75 kg/ha), N2 (100 kg/ha), N3 (125 kg/ha)) and two levels of intra-row spacing (S1 (70×25cm) and S2 (70×30cm)). The inter row spacing was maintained as 70cm. The experiment was laid out in 3×2 factorial arrangement in a randomized complete block design (RCBD) and replicated three times. The analysis of variance revealed that the main effects of intra row spacing and nitrogen rates as well as the interaction of the two factors had a significant effect in all tested growth parameters of hot pepper. The main effect of nitrogen resulted maximum plant height (49.92cm), leaf number per plant (35.45), and number of branch per plant (10.92) which were recorded by the application of 125kg/ha nitrogen. Likewise, the main effect of intra row spacing gave maximum plant height (49.52cm) at 25cm plant spacing, and leaf number per plant (35.30), and number of branch per plant (11.21) from 30cm plant spacing. For interaction effect, the highest plant height (52.00cm) were recorded from S1N3 (25cm plant spacing and 125kg/ha N), whereas the maximum leaf number per plant (38.83) and number of branch per plant (12.67) were obtained from S2N2 (30cm plant spacing and 100kg/ha N fertilizer). Mostly, leaf number and number of branch positively correlated with yield of the crops where the branch increased fruit setting become increased as a result yield increased. Therefore, applying 100 kg/ha N with 70×30 cm plant spacing can be advisable for hot pepper production.
