background and objectives: germination and seedling establishment are two critical and important stages during plants growing season. from seed technology viewpoint, germination refers to emergence and development from seed embryo, so that could produce normal seedling. many studies  have been done to determine germination cardinal temperatures and required thermal time for emergence occurrence...

winter sown chickpeas produce more yields in comparison with spring type. this function is hampered by the sensitivity of the crop to low temperature. in order to study and identify high yielding and cold tolerant chickpea (cicer arietinum l.) lines, 65 entries along with one susceptible check variety namely ilc533 were evaluated in a randomized complete block design (rcbd) with two replication...

Objective: An experiment was conducted at Wondo Genet Agricultural Research Center in the production season of 2013/14 and 2014/15 with the objective of identifying the best combination of intra and inter-row spacing for optimum plant population density of stevia. Methods: The experiment was conducted using five intra-row spacing (20cm, 25cm, 30cm, 35cm, and 40...

drought causes significant reductions in crop productivity in many parts of the world, including iran. identifying genotypes tolerant to drought stress is therefore one of the foremost goals of crop breeding programs. this study investigated the effect of terminal drought stress on yield and yield components of new winter rapeseed lines, and identified new winter rapeseed lines tolerant to term...

in order to investigate the effect of water deficit irrigation and natural products on vegetative characteristics of three varieties of chickpea, a field experiment was performed as split-split plot experiment in a randomized complete block design with three replications during 2011 growing season in shahrood (miami). the main plot was drought stress in four levels including normal irrigation (...

Studies in the Andes have demonstrated that seed degeneration of potato occurred experimental conditions, but was negligible farmers' conditions. There are two hypotheses for this difference: (1) farmers cultivate resistant varieties, or (2) they use on-farm practices can manage degeneration. Farmers may replace some saved from their fields with outside seed, it is an open question what level b...

Methods: The experiment was conducted using five intra-row spacing (20cm, 25cm, 30cm, 35cm, and 40...

Abstract During the growth season, plants of rapeseed ( Brassica napus L.) and brown mustard juncea are affected by various diseases: Fusarium blight, Verticillium Alternaria others. The cultivation varieties resistant to diseases is a cost-effective environmentally safe way protect from diseases. aim work was evaluate new breeding material spring for resistance blight in form tracheomycotic wi...

Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30,...
