Pepper and Onion Yield Estimate Parameters as Affected by Seed Treatment Options: In the Selected Districts of Central Rift Valley; Oromia Regional State of Ethiopia

Abstract

Pepper and onion yield estimate parameters were conducted during off-season of 2011 using irrigation both at on-station and at on-farm of Adami Tulu Agricultural Research Center and its surrounding districts of Adami Tulu, Dugda and Bora district of central rift valley by participating important influential actors (farmers, NGOs, DAs, district agricultural officers, etc.) from the inception to evaluate different seed treatment options that can favor onion and pepper yield estimate parameters. Bombey red and Marekofana of high yielding, disease tolerant, early maturing, market and farmer preferred varieties were used for the research by collecting from Adami Tulu Agricultural Research Center. Data on performance of yield estimate parameters were evaluated until it was transferred to permanent field. The on-station data analysis result indicated that except root length and greenness of onion and seedling thickness and greenness of pepper, majority of yield estimate parameters were statistically (P < 0.05) significant while root length, shoot length and shoot height of onion on-farm were statistically (P < 0.05) non-significant. For on-station onion, hot water treatment supplemented with dressing the seed with half recommendation rate of apron-star resulted in the highest yield estimate parameters for most of the variables collected. Although there was an absence of consistent for all traits under analysis, sowing seed without any treatment resulted to the lowest count or measurement. But seed treated with mancozeb as per the recommendation gave the highest score or count for pepper except that of leaf number and greenness in which hot water treatment alone resulted in highest count. Even though yield estimate parameters don't totally reflect actual attainable yield at the end of harvesting, seedlings that were superior for those traits mostly reflect yield if different management options applied as per recommendation set for the crops. * Capacity building for scale up of evident based best practice in agricultural production in Ethiopia.

Participatory demonstration and evaluation of improved onion variety in East Shewa zone of Oromia regional state, Ethiopia

“…It is grown under both irrigation and rainfed conditions, by smallholder farmers and commercial growers, with, irrigation covering the majority of the land [1]. The study area has a high potential for onion production b ecause of the abundance of irrigated farmland and the presence of relatively better market access [2].…”

“…These low yield results indicate the presence of a large productivity gap, which is attributed to several constraints, the most significant of which are the lack of an authorized body that produces and distributes improved onion seed varieties and the use of inappropriate agronomic practices [2,4]. With this in mind, the purpose of the study was to compare the performance of a recently released onion variety (Nafis) with the check (Bombay red) through on-farm demonstration and to analyze farmers' preferences for the demonstrated varieties.…”

Participatory Demonstration and Evaluation of Onion Varieties in Lume and Dugda Woredas, East Shewa Zone of Oromia Regional State, Ethiopia

“…Onion is cultivated by smallholder farmers and commercial growers both under the irrigation and rain feed conditions where the larger area is covered under irrigation (Asfaw, 2015). East Shewa zone, the study area, has great potential for onion cultivation, due to the availability of sufficient irrigated farmland and the presence of relatively better market access as compared to the other areas (Teshome et al,2015).…”

“…This low yield results indicate that the presence of a huge gap in productivity. This is attributed to several constraints among which the absence of an authorized body that produces and distributes the improved onion seed varieties and the application of inappropriate agronomic practices are the major ones (Mahlet, 2012;Teshome et al, 2015). Hence, with these in view, the study was carried out to show the performance of recently released onion varieties with their recommended agronomic recommendations (Nafis and Nasik red) and compare their performance with the one that farmers are using (Bombay red) through on-farm demonstrations and evaluation.…”
