The study was undertaken from mid September 2006 to January 2007 at Dembia trial site of Gondar Agricultural Research Center, Northwest Ethiopia. The four improved grass pea lines, ILAT-LS-LSB1, ILAT-LS-LS-B2, ILAT-LS-K-290 and ILAT-LS-61'8 were brought from Debre Zeit Agricultural Research Center (DZARC) and the two lines, Kok-Egir and Shanko were collected from the study area based on their seed color. They were replicated thrice and arranged in a Randomized Complete Block Design (RCBD). Analysis of variance showed significant (P '305) variation among grass pea accessions on straw, seed and total biomass yield. The highest Dry Matter Yield (DMY) was found from grass pea accessions of Shanko and Kok-Egir with values 7.49 and 7.88 t/ha, respectively. The highest seed and straw yield were recorded from Shanko with values 4.40 and 7.00 t/ha, respectively. There was no significant difference (P '305) between treatments of Crude Protein (CP) content in forage biomass, grain and straw. The present study also provided very important data that may be utilized in research and developmental activities from local land-races and improved lines of grass pea. Additional comprehensive study is required to evaluate the impact on meat and milk through feeding of grass pea grain and fodder.
Lathyrus sativus or grass pea, is a drought tolerant large seeded legume that is well adapted to dryland temperate climates like that of Saskatchewan. The use of this crop for feed and food is limited because it contains the neurotoxin B-N-oxalylamino-L-alanine (BOAA). A 3-year study was conducted to determine the effect of moisture addition by irrigation on BOAA concentration in the seed of the grass pea in light textured soil.
One of the world centers of crop evolution and origin, Ethiopia has long been recognized as an important area of diversity for several major and various minor crops. Based on an international conference held in Addis Ababa, this book describes how plant genetic diversity in Ethiopia is of vital importance in breeding new varieties of crops with desirable characteristics, such as increased resistance to pests and diseases and greater adaptation to heat and drought. The three main sections in the book consider the Ethiopian center of diversity, germ plasm or genetic material collection and conservation in Ethiopia, and the evaluation and utilization of Ethiopian genetic resources. A broad range of food and feed crops and plants of medicinal and industrial importance are discussed, both at a national and international level. A brief account of conservation strategies and gene bank problems unique to Ethiopia is also given. The importance of Ethiopia's plant genetic resources to world agriculture has been demonstrated on more than one occasion. Plant breeders, geneticists, and botanists throughout the world will, therefore, find this unique book a valuable source of information and an essential reference work.
