Role of Neem based Biopesticides to control agricultural pest as an Environmental friendly management
Abstract: The present study aims to review various applications, advantages and shortcomings of different formulations of Neem-based bio-pesticides. The term bio-pesticide refers to the use of cow urine, plant extracts or microbial formulations, or a combination of these. The production of bio-pesticides involves simple strategies and thus they are very economical compare to chemical pesticides. The yield and quality of various agricultural and horticultural produces are adversely affected by the attack …

Effects of NPS Fertilizer Rates on Yield and Yield Components of Potato (Solanum tuberosum L.) Varieties in Southern Ethiopia
Abstract: Solanum tuberosum L. is a high-yielding crop that can be produced twice or four times per year. But its yield is limited due to low soil fertility and limited use of improved varieties. The study's objective was to identify the blend NPS fertilizer rates for potato varieties yield and yield components. The experiment was carried out using a factorial Randomized Complete Block Design (RCBD) with three replications. The results revealed …

The Effect of Urea Fertilizer Rate and Spacing on Dry Matter Yield of Desho Grass-Alfalfa (Medicago Sativa L) Mixture in Mid Altitude of Southern Ethiopia
Abstract: Economic development in developing countries is unable to keep pace with the population growth and food/feed shortage. Growing high yielding quality forage crops with appropriate agronomic packages and using cropping systems that enable to produce two or more forage crops in a year at the same place is essential. Experiment was therefore conducted to evaluate the effects of urea fertilizer rate and row spacing on the morphological characteristics, yield and …

Cluster based large scale Demonstration of improved wheat varieties in Silte zone, Southern Ethiopia
Abstract: Cluster Based Large Scale Demonstration of wheat was conducted at Alicho district and Worabe administrative town of Silte zone to increase production and productivity among wheat producer farmers. Once more, kebeles were purposefully chosen from each district based on the potential of the crop for producing wheat. From selected kebales115farmers were benefited from this intervention on 80 hectares of land clustered on three sites in 2021/22 cropping season. Ogolecho and …
