Abstract: Alternate furrow irrigation was believed to improve water use efficiency and labor without a significant tradeoff in yield. It leads to see the effect of alternate furrow irrigation versus every furrow and fixed furrow were evaluated at full crop water requirement. With the objective of to evaluate effect of alternate furrow irrigation with two irrigation intervals (5day and 3day intervals) on crop yield water productivity that might enable to save irrigation water and labor. The experiment has been under taken among AFI, FFI and CFI at Adami Tulu Agricultural Research Center of experimental site for onion production. A field experiment was designed as a two factor factorial experiment (3*2) in RCBD, replicated three times. The two factors were irrigation systems and irrigation interval. Irrigation was applied to furrows using Parshal flume from furrows head ditch with similar inflow rate. Results obtained revealed that alternate furrow irrigation method produced total yield of 25203kg/ha which was not significantly different with that obtained under every furrow irrigation (26469kg/ha). Total yield harvested from fixed furrow irrigation were 24024kg/ha, which showed insignificant difference between the three methods. High marketable yield of 26053kg/ha was recorded from every furrow irrigation and the marketable yield of alternate furrow irrigation were 24601kg/ha which showed insignificant difference between the two method. Water productivity of 7.6kg/m3, 7.3kg/m3 and 5.9kg/m3 were produced under alternate furrow, fixed furrow and every furrow irrigation respectively. It was found that alternate furrow irrigation method saved 26.61% of water as compared to every furrow irrigation as well as fixed furrow irrigation method saved 26.81% as compared with every furrow irrigation method. Alternate furrow irrigation method with appropriate irrigation interval that is three days of irrigation interval is suitable irrigation method; for semi arid areas where soil is dominated by loam soil and water is liming factor for crop production.

Abstract: Double-cropping cereals with legumes is a usual practice by smallholder farmers in southern Ethiopia. However, crop compatibility and sequencing are the major problems for their soil fertility and profitability. Thus, it was useful to conduct experiments on double cropping systems that enable the farmers more profitable on small land to reduce crop failure with current climate change. Thus, an experiment was done to evaluate the effects of the common bean as double cropping on the productivity of tef and to evaluate the economic and technical compatibility of common bean-tef in a double cropping combination to improve production at Wondo Genete district during the cropping season of 2021 using RCBD design. The experiment consisting of twelve treatments including three common bean and three tef varieties was sowed as the preceding and succeeding crop respectively and three sole tef variety to see the compatibility of common bean and tef varieties. The preceding crops showed a non-significant difference in days to maturity, seed per pod, and hundred seed weight, but the biomass and grain yield of Remeda were significantly higher than Awash-2 however, it had no significant yield difference with Hawassa Dume. The variance analysis showed that all the growth and yield parameters of tef were significant such as days to heading, days to maturity, plant height, spike length, number of tillers per plant, tiller number, and grain yield (p<0.05). However, the yield parameters like dry biomass, straw yield, and toughened seed weight for tef had no significant difference.

Abstract: The study was about the adoption of black plastic mulches as a copying strategy to water conservation among smallholder vegetable farmers in Kisoro Municipality, Kisoro district. Farmers in Kisoro District have increasingly adopted black plastic mulch to address these agricultural challenges. The use of black plastic mulch in this region helps in conserving soil moisture, controlling weeds, and enhancing crop yields. It was guided by three specific objectives which were to; establish the socio-economic characteristics of smallholder vegetable farmers, establish the knowledge level on the benefits of black plastic mulch among smallholder vegetable farmers and examine the factors influencing farmer’s decision to adopt black plastic mulch as a coping strategy to water conservation. The study employed a cross-sectional study design that used both quantitative and qualitative approaches. The study used a sample size of 300. The study used questionnaires and interview guide to collect data. The data collected was analysed using Statistical Package for Social Scientists (SPSS). The results revealed that land ownership was a positive and significant factor at (sig. 0.000**), source of income at (sig.0.001*), credit accessibility at (sig.0.002**) and knowledge on use of black plastic mulches at (sig. 0.000**) The study concluded that vegetable farmers were characterized in terms of gender, age, farm size, marital status and level of education. The study also concluded that there was adequate knowledge level on the benefits of black plastic mulch among smallholder vegetable farmers. Such as; leads to higher yields and improved quality of vegetables, increase the growth rate of vegetables, reduce the risk of root damage, weed suppression, moisture conservation and contribute to soil health and protect the soil from wind and water erosion. The study finally concluded that there were significant and non-significant factors influencing farmer’s decision to adopt black plastic mulch as a coping strategy to water conservation among smallholder vegetable farmers which included; land ownership, limited extension training, source of income, knowledge on use of black plastic mulches and credit accessibility and non-significant ones were; un-availability of labour, infrastructure development, level of education, price of black plastic mulch and farm size.
