Abstract

The experiment was conducted to determine the effects of vermicompost with equivalent nitrogen ratios on soil chemical properties and onion production in Northwestern Ethiopia. The experiment comprised six treatment levels: Control, Recommended Nitrogen, 75% Recommended Nitrogen + 25% Vermicompost, 50% Recommended Nitrogen + 50% Vermicompost, 25% Recommended Nitrogen + 75% Vermicompost, and 100% Vermicompost. These were arranged in a Randomized Complete Block Design (RCBD) with three replications. Data were analyzed using Analysis of Variance (ANOVA) via SAS software. The results showed that vermicompost combined with nitrogen affected the yield components of onions. However, soil properties, except for Total Nitrogen (TN) and Organic Carbon (OC), were not significantly affected by the treatments. The application of 50% vermicompost with 50% nitrogen resulted in the highest bulb yield (23.6 t/ha) compared to the control. Therefore, for a quick improvement in yield, applying 50% vermicompost with 50% nitrogen can be preferable in the study area and areas with similar agro-ecological conditions to achieve the highest net benefit.

Abstract

Textile produces large volumes of sludge due to industrial activity, and its disposal is a serious environmental concern because it includes toxic contaminants, including heavy metals. Due to its vast volume and mass, sludge management is seen as an additional burden to the industry. This study aims to characterize solid sludge from the textile industry. The sludge’s pH, organic matter (OM), nutrient elements (N, P, K), and metal content were determined using appropriate analytical techniques. Treatment consisted of 4×3 factorial combinations of nitrogen and phosphorus, i.e., full recommended (100 kg N and 50 kg P), half recommended (50 kg N and 25 kg P), control, and dried sludge at 0, 5, 10, and 20 tons per ha. The textile industrial sludge’s Cu, Cr, Fe, Cd, Pb, and Zn concentrations are 511.568, 251.166, 7991.667, 67.333, and 463.00, respectively. The Cu, Cr, Fe, and Zn concentration levels exceeded the recommended upper limit for agricultural soil. Nonetheless, cadmium and lead are below WHO standards. Soil pH, % total nitrogen, % total organic content, and % organic matter increased after sludge application. Applying textile sludge to soil considerably raised the soil Cr, Fe, and Cu contents compared with the control, and lettuce growth increased from 75 g to 143.5 g per pot after applying 20 tons of sludge per ha. Therefore, textile sludge could be an alternative to organic fertilizer or soil conditioner if metals, especially Fe and Cr, are reduced by proper treatment strategies.

Abstract

A pre-scale-up study was conducted at the Barneb small-scale irrigation scheme to promote improved irrigation technologies for malt barley, aiming to enhance water use efficiency, farm productivity, and the economic benefits of smallholder farmers. Traditional flooding methods were found to be inefficient due to water wastage, soil erosion, and waterlogging. To address these issues, a Farmer Research Group (FRG) consisting of 30 farmers (26 male and 4 female household heads) was established. The improved irrigation practice involved double row raised bed furrow irrigation with a 40 cm bed width, 20 cm furrow width, and 20 cm row spacing, along with recommended fertilizer rates (100 kg ha⁻¹ Urea and 100 kg ha⁻¹ NPS). Net irrigation depths were 19 mm during the initial stage and 44.3 mm during the mid-season stage, with irrigation applied at 30-day intervals. Results showed that improved seed combined with improved irrigation and agronomic practices yielded 4,250 kg ha⁻¹, a 25% increase over the 3,400 kg ha⁻¹ yield from local seed under traditional practices. Water productivity also improved significantly, with the improved method achieving 4.7 kg m⁻³, nearly double that of the farmer's practice (2.4 kg m⁻³). The net benefit from improved practices was 133,300 ETB ha⁻¹, which is 55.14% higher (47,375 ETB ha⁻¹ more) than the 85,925 ETB ha⁻¹ achieved through traditional methods. In conclusion, the study recommends scaling up the improved technologies through collaborative efforts between the Ministry of Agriculture, NGOs, and private sectors via integrated irrigation extension programs.

Abstract

In the semi-arid regions of Eastern Amhara, inadequate and unevenly distributed rainfall negatively affects rainfed agriculture, particularly maize production. To address this, a pre-scale-up study was conducted to evaluate improved irrigation technologies using the Farmer Research Extension Group (FREG) approach. Two irrigation practices traditional and improved were compared at Golina1 and Sedeni sites. The improved practice included the use of the Melkassa-6Q maize variety, row planting (75 cm × 30 cm), furrow irrigation (with specific dimensions and gradient), a seed rate of 25 kg ha⁻¹, and recommended fertilizers (200 kg ha⁻¹ Urea and 50 kg ha⁻¹ NPS). In contrast, the traditional practice involved local varieties, broadcast sowing (40 kg ha⁻¹), traditional flooding at 12-day intervals, and lower fertilizer rates (50 kg ha⁻¹ Urea and NPS). The improved practice significantly outperformed the traditional method, achieving higher green cob yields (38,125 ha⁻¹ at Golina1 and 34,330 ha⁻¹ at Sedeni), better water productivity (17 and 16 cobs m⁻³), and greater net benefits (222,575 ETB ha⁻¹ and 174,487 ETB ha⁻¹, respectively). This represented yield increases of 29.9% and 30.2%, and net benefit improvements of 79.63% and 86.84% over traditional practices. Additionally, improved irrigation reduced seasonal water demand by 72.4 mm and 131.6 mm, indicating substantial water savings.Overall, the study demonstrated that improved irrigation and agronomic practices significantly enhance maize yield, water use efficiency, and profitability, and were positively received by participating farmers.
