Effect of Genotypes, Environment and Grown Year on Nutritional Composition and Functional Properties of Promising Ethiopian Chickpeas Varieties (Published)
Chickpea is a major source of energy and micronutrients for majority of population in Africa. However, comprehensive studies have not reported on the effects of genotype, cultivation location, and year on chickpea flour characteristics. To address this, 11 selected chickpea varieties were grown at three locations in Ethiopia, during 2010 and 2011, representing three environments, and composition of proximate, minerals and functional in chickpea flour were determined. The cultivation environment, the cultivation year and the chickpea genotypes, as well as their interactions significantly affect the functional properties and nutritional composition of chickpea. High proportion of the total variation for all studied parameters explained by the main effects of variety indicates a significant heritability for them. Growing location was found to have a significant effect on all functional properties except OAC, total ash, crude fat, crude protein, carbohydrate, energy, calcium, magnesium, iron and zinc. Year was found to affect OAC, WAC, SC, FS, EA, total ash, calcium, magnesium, iron and zinc. Rainfall is the climate characteristic that may be responsible for these year-dependent differences. HC and SC (r = 0.902) and energy and fat (r = 0.800) shows positive correlation whereas, carbohydrate and protein (r = -0.896) and energy and fiber (r = -0.674) showed negative correlation. The current study established a better understanding of the varietal effects of genotype and environment on functional and nutritional composition properties of chickpea flours.

EFFECT OF PHOSPHORUS FERTILIZER ON YIELD AND YIELD COMPONENTS OF CHICKPEA/ CICER ARIETINUM) AT KELEMEDA, SOUTH WOLLO, ETHIOPIA (Published)
Filed experiment was carried out to study the effect of varying levels of phosphorus (T1= 0kg/ha, T2= 30kg/ha, T3= 60kg /ha, T4=90kg/ha and T5 =120kg/ha) on growth performance and yield of chickpea (Cicer –arietinum) variety Aratiy at the experimental field of Wollo university, Kelem meda, during winter season in 2013. The results revealed that phosphorus levels significantly affected plant height, number of branches per plant and number of pods per plant. The maximum plant height (39.25cm) was recorded from plots received 60kg P 2O 5 ha -1, while the minimum plant height (32.5cm) was recorded from the control. Similarly higher number of branches per plant was recorded from the same treatment. The maximum number of pods per plant (49) was observed from the application of 60kg P 2O 5 ha -1. Generally the results revealed that the application of 60kg P2O5 ha -1 better performance in all of the parameters studied. However this research was conducted using irrigation, in one location and season. Thus, it should be replicated in multi-location and season so as to assure the results of the experiment
