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

Pre-scale up study was conducted to promote Malt Barley improved irrigation technologies for enhancing water use efficiency, farm productivity, and the benefits of smallholder farmers at Barneb small-scale irrigation scheme. The rationality was that improved irrigation method is preferable for water saving, increasing yield, decreasing water logging and soil erosion, enhancing water productivity and easily for water application than the traditional flooding method. In order to achieve these objective farmers research was established with 30 (26 male and 4 female household heads) members. The fertilizer was applied as 100 kg ha-1 Urea and 100 kg ha-1 NPS rate. Double row raised bed furrow technology with 40 cm bed width, 20 cm furrow width, and 20 cm row spacing were applied. The net irrigation applied depths were 19 mm for initial stage and 44.3 mm for mid-season stage with 30-days irrigation interval. The result shows that the application of improved seed with improved management practices had nearly doubled water productivity (4.7 kg m-3) over the farmer's practice (2.4) kg m-3). Therefore, Ministry of Agriculture in collaboration with non-government organizations and other private sectors should work to scaling the technologies through irrigation extension packaging system.

Abstract

Inadequate rainfall with uneven distribution in time and space could harm the rainfed agriculture in the semi-arid regions of Eastern Amhara. Hence, irrigation is crucial to provide crop production and economic benefit. Therefore, the pre-scale-up aimed to promote improved irrigation technologies to increase grain yield, water use efficiency, and net benefit of maize. For comparison, two forms of irrigation practices (traditional and improved) were tested following the Farmer Research Extension Group (FREG) approach. The improved irrigation practices include agronomic packages (200 kg ha-1 Urea and 50 kg ha-1 NPS, seed rate of 25 kg ha-1, the spacing between rows and plants were 75 cm and 30 cm respectively), furrow irrigation (0.15 m furrow height, 0.25 m furrow width, and 0.2% furrow gradient). In Sedeni and Golina1, the net irrigation depths were 11.2 mm and 12.4 mm, 28.4 mm and 30.6 mm, 36.6 mm, and 37.8 mm, and 24.7 mm and 27.4 mm for initial, development, mid, and late stages, respectively. Depending on the agroecological similarities of the two sites, the irrigation was applied in 10-day intervals. The farmer's practice included: a local variety, broadcast sowing with 40 kg ha-1, traditional flooding applied in 12 day intervals, 50 kg ha-1 Urea and NPS each. The quantitative data was recorded by field monitoring and the farmer's perceptions were collected from the FREG members using a semi-structured questionnaire survey. The collected data was analysed by descriptive statistics. The result showed that the maximum marketable green cob yield (38,125 and 34,330 cobs ha−1), water productivity (17 cobs m-3 and 16 cob m-3), and maximum net benefit (222,575.00 ETB ha-1 and 174,487.00 ETB ha-1) for Golina1 and Sedeni respectively was recorded from the improved practices. Whereas farmer's practices gave minimum green yield (29,351 ha−1 and 26,368 ha−1), water productivity (10 cob m-3 and 8 cob m-3), and net benefit (123,905.00 ETB/ha, and 93,390.00 ETB/ha,) for Golina1 and Sedeni, respectively. Therefore, improved irrigation and agronomic practices had 29.9% and 30.2% green cob yield, and 79.63% and 86.84% net benefit advantage for Golina1 and Sedeni, respectively. In these respective small-scale irrigation schemes, the improved practices had lower seasonal net irrigation water demand (230 mm and 219.4 mm) than the farmer's practices (302.4 mm and 351 mm). It implies that the improved practices saved 72.4 mm and 131.6 mm of water for Golina1 and Sedeni respectively over the farmer's practices. Hence, from the result, it could be concluded that improved irrigation management practices (furrow irrigation, irrigation frequency, amount, row planting, plant spacing, seed rate, and recommended fertilizer, and improved seed Melkassa- 6Q) were more efficient in achieving high green cob yield, water productivity, water saving, higher net benefit, and acceptability by the FREG members.  Keywords: FREG, scale up, Small-scale irrigation, technologies.
