Genotype by environment interaction (GxE) as a measure of yield stability of Dutch potato varieties in Uganda
Twenty one (21) Dutch potato varieties were introduced in Uganda during 2015-2016 seasons for national yield performance and adaptability studies so that most stable varieties could be identified for production. The effect of genotype (G), environment (E) and their interaction (G x E) on tuber yield was assessed to establish variety adaptation in different agro ecologies. Five sites were used in the study that...
Uncertainty, risk aversion, and management strategies â€“ A case of cocoa farmers in Osun State Nigeria
Risk is a major issue that affects so many aspects of people’s livelihoods in the developing world. It is imminent in all management decisions of agricultural systems, as a result of fluctuations in price, yield and resource uncertainty. Hence, uncertainty, risk aversion and management strategies were investigated among the cocoa farmers in Osun State, Nigeria. Primary data employed in the study were obtained from...
Response of groundnut (Arachis hypogaea L.) to plant growth promoting Rhizobacteria in degraded soils
The effects of plant growth promoting Rhizobacteria (PGPR) on the growth, plant nutrient content and crop yield of groundnut (Arachis Hypogaea L.) cv. Golden were investigated under rainfed conditions in degraded lands within 2011 and 2014. The experiment was planned with a randomized complete block design having three replication. The two PGPR treatments alone or in combination with FYM were tested and compared with...
The permanence in the plantation after harvest damages physical characteristics of Conilon coffee grains
The permanence of harvested fruits in the plantation can cause irreversible damage to Conilon coffee quality, possibly increasing the overall number of defects, causing losses to crop yield and changing the organoleptic properties of the product. The objective of this study was to quantify the changes caused by permanence time of the Conilon coffee in the plantation after harvest over the mass and classification of the...
Single-line automated sorter using mechatronics and machine vision system for Philippine table eggs
An automated single-line table egg sorting machine that integrates machine vision and mechatronics principles was developed in this study. The machine was fabricated using low cost and locally available materials. The developed machine was composed of the feeding unit, computing unit and the sorting unit. The conveyor was powered by a 12V DC geared motor, and the sorting arm was actuated by a DC servo motor which...
Performance of bread wheat genotypes under different environment in lowland irrigated areas of Afar Region, Ethiopia
Wheat is an important staple food for Ethiopian people, and its straw has been used as sources of feed for animals. Nine wheat genotypes introduced from International Center for Agricultural Research in the Dry Areas (ICARDA) were evaluated at Werer Agricultural Research Center from 2010/2011 to 2013/2014, at Gewane from 2011/2012 to 2012/2013 and at Waidulale in 2013/2014 cropping seasons using randomized complete...
