Abstract: Through the use of path coefficient analysis and correlation, crop breeders can improve complex traits like grain yield through indirect selection. The current study set out to quantify the relationship between yield and traits related to yield as well as pinpoint critical features for indirect selection aimed at enhancing the grain yield of faba bean. The objective of the current study was to identify key characteristics for indirect selection targeted at increasing the grain yield of faba beans as well as quantify the relationship between yield and variables related to yield. The study was conducted at Fogera National Rice Research and Training Center at the Debre Tabor research site used a 7x7 simple lattice design with two replications to evaluate 49 faba bean genotypes during the rainy cropping season of 2022. The study found a significant positive correlation between grain yield, plant height, pod number, biomass yield, 100-seed mass, and harvest index. The study found that biomass yield and harvest index significantly impact grain yield, suggesting they can be used as indirect selection criteria to enhance faba bean grain yield.

Abstract: Establishing of grass-legume pastures is one of the recognized strategies for enhancing both quantity and quality of feed resources. Therefore, determining the impact of seed proportion on the nutritional qualities and forage yield of combinations of guinea grass and green leaf desmodium is the goal of this study. A Randomized Complete Block Design (RCBD) with three replications was used to arrange five seed proportions of desmodium and guinea grass. Analysis of variance revealed that variations in treatments have significant differences (p<0.05) on panicum heights, desmodium tillers, and Desmodium height. In addition, the effects of years showed significant (p<0.05) effects on panicum tiller, desmodium height, and percentage of coverages. Interaction of treatments with years showed a significant effect on tiller per plant and plant heights while the other parameters weren’t influenced. The combined mean of dry matter and percentage of coverage have showed significant differences (p<0.05) between the treatments. This result reveals that the seed proportion have effect on the dry matter and percentage of plant coverages. The aggressivity index also has significant mean differences (P<0.05) between the treatments. Legumes with the lowest proportion (25%) performed less competently than those with the highest proportions (75%) and 50% D. intortum. The crowding coefficient of P. maximum and D. intortum mixed forage showed significance differences (P<0.05). However, the value of seed proportion on crowding coefficient of panicum maximum and desmodium intortium were more than one. The LER has significant differences (P<0.05) due to ratio of P.maximum and D.intortium mixture and its value at T2, T3, and T4 showed as to be (LER>1) that revealed the yield advantages. Cobined mean results showed that there is significance difference (P<0.05) of CP, Ash, ADF, NDF and ADL due to different seed proportion mixture. In addition the CP of panicum incurred from 8.24% to 18.55% by mixing different seed proportion of D.intortium. An integration of legume forage with grasses improves the feed quality and quantity. Thus, based on the dry matter, yield advantage and nutritive values the integration of 75% and 50% desmodium is recommended for use in the study areas and similar agro-ecologies.

Abstract: The results of this research provide a basis for additional exploration and advancement, which will culminate in suggestions for the timing of split urea treatment and cultivars for sustainable maize production within the study region. During the 2019 and 2020 growing seasons, a field experiment was conducted at the Bako Agricultural Research Center to determine the response of hybrid maize cultivars to urea split application on phenology, growth, and grain production. In the experiment, six levels of urea split application were applied to two types of corn. T1 = 1/2 dose of urea at planting + 1/2 dose of urea at Knee height; T2 = 1/2 dose of urea at planting + 1/2 dose of urea at tasseling; T3 = 1/ 3 dose of urea at planting + 1/3 dose of urea at knee height + 1/3 dose of urea at tasseling; T4 = 2/3 dose of urea at knee height + 1/3 dose of urea at tasseling; T5 = 1/2 dose of urea at knee height + 1/2 dose of urea at tasseling; and T6 = 1/4 dose of urea at planting + 1/2 dose of urea at knee height + 1/4 dose of urea at tasseling. The experiment's randomized complete block design made use of three replications. The primary effects of the urea split time of application were found to have a substantial impact on plant height, 90% physiological maturity, grain production, total leaf area per plant, and leave area index. Three urea split applications 1/4 dosage at planting, 1/2 dose at knee height, and 1/4 dose at tasseling provided the maximum net benefit of EB 246,536.7 ha-1 and the best marginal rate return of 2822.26% for maize output. In conclusion, urea split application 1/4 doses at planting stage 1/2 dose at knee-height and 1/4 dose at tasseling stage is the best time of application in good rainy seasons and hence recommended for the end users. However, in the case of erratic and heavy rainy seasons, application at three times should be used to get maximum profit and acceptable MRR.

Abstract: Finger millet is a major grain crop in the west hararghe zone. However, due to major constraints like lack of improved varieties and drought, the productivity is by far lower than the genetic potential of a crop in the study areas. Thus, current study initiated to obtain high-yielding and stable varieties. The study was conducted in districts of Habro, Mechara, and Gamachis of the west hararghe zone, using eight improved and one standard check finger millet varieties at 2020 main cropping seasons. The experiment was laid down in a randomized completely block design with three replications. Analysis of variance for grain yield across locations showed significant differences at p< 0.05. Further analysis of AMMI indicated that environments, varieties, and their interaction effects were significantly different. Even if, tested materials showed a significantly different grain yield across locations nevertheless, the GGE bi-plot analyses implied relatively high yielding and consistent across environments for varieties Bako-09, Gudetu, and Addis-01. Therefore, these varieties of finger millet were recommended for further evaluation at the farmer’s field.

Abstract: Agricultural practices such as the application of organic and inorganic fertilizers play a crucial role in enhancing crop productivity. The impact of poultry manure and NPK (15:15:15) fertilizer on the growth and yield of tomato (Lycopersicon esculentum L.) was examined in Owo, South Western Nigeria. This study employed a randomized complete block design (RCBD) with three treatments (No manure as control, NPK (15:15:15) at 200 kg/ha, and poultry manure at 2.5 t/ha) allocated randomly across plots using balloting methods, each replicated thrice. Seedlings were spaced at 30 x 60 cm, resulting in a total of 108 stands across nine plots. Various parameters including plant height, stem girth, number of leaves, number of flowers, number of fruits, and fruit weight were assessed through statistical analysis. Results showed that poultry manure significantly enhanced vegetative growth parameters such as plant height, leaf number, and leaf area compared to the control. At 2, 4, and 6 weeks after transplanting (WAT), poultry manure consistently outperformed NPK in terms of plant height and leaf area. However, NPK showed a superior number of flowers and fruit yield, highlighting its rapid nutrient release and immediate availability. Despite NPK's effectiveness, the overall yield attributes of poultry manure were comparable, suggesting its potential as a sustainable alternative due to its soil-enriching properties and long-term benefits. This study underscores the importance of integrating organic and inorganic fertilizers to optimize tomato yield and soil health, advocating for further research into the economic and long-term impacts of organic fertilization in tropical agriculture.
