Abstract

Ineffective use of water consumption usually causes problems such as increased land salinity, waterlogging, land salinization, waterlogging, reduced crop productivity and water loss. This experiment was conducted to study the effects of irrigation levels and mulching materials on yield, yield components, and water productivity of hot pepper in Odo Shakiso district, Southern Oromia region during 2021-2022. The experiment was designed as a combination of nine treatments and was repeated three times under a completely randomized block design (RCBD). Treatments included three levels of irrigation application (100% ETc, 85% ETc, and 70%) and three types of mulch (no mulch, straw mulch, and white plastic mulch). The combination effect of irrigation levels with mulch type under convectional furrow irrigation has shown a highly significant (p<0.01) influence on plant height, number of pods per plant, marketable yield, total yield, and water productivity of green hot pepper. The highest marketable and the highest total yield of green pepper were obtained under 100% ETc and white plastic mulch treatment with 15.46 tons of green pepper per hectare and 15.54 tons of green pepper per hectare respectively. However, statistically, there is no significant difference among treatments of 100% ETc without mulch, 100% ETc with white plastic mulch, 100% ETc with straw mulch, 85% with white plastic mulch, and 85% ETc with straw mulch. Moreover, the maximum water productivity (4.74kg/m3) was observed at irrigation application of 70% ETc with white plastic mulch which was statistically non-significant with irrigation application of 85% ETc with white plastic mulch and 85% ETc with straw mulch with the value of (4.61kg/m3) and (4.46kg/m3) respectively. Based on the partial budget analysis, the highest net benefit value of 839,438 birr/ha with marginal rate of return (1080) was obtained from irrigation water application of 85% ETc under straw mulch. This result revealed that applying irrigation of 85% ETc with straw mulch is economically feasible for green hot pepper production in the Odo Shakiso area of the Guji zone. In conclusion, the present study points out that irrigation application of 85% ETc with straw mulch is recommended for the Odo Shakiso district and other similar agro ecologies. However, as the trial was conducted in one location, conducting similar research over locations would be appropriate to get conclusive results for the best recommendation.
