A field experiment was conducted in the Agricultural Research Station, at El-Ghoraieb, Assiut to study dry seed yield performance of two locally adapted cultivars (‘Azmerly’ and ‘Cream 7’) and two line introductions (IT81D-1032 and IT82D-812) of common cowpea (Vigna unguiculata (L.) Walp) grown at three different within-row spaces (20, 30 and 40 cm) and two planting dates in the summer (April 1...

introduction the study of growth parameters such as net assimilation rate (nar), leaf area ratio (lar), relative growth rate (rgr) and leaf area duration (lad) are important for analyzing yield constraints. the growth parameters can be used to understand the crop response to environmental variables during the growing season. the aims of the present study were to 1) consider the growth indices u...

Annual bluegrass (Poa annua L.) turf quality is reduced during periods of high temperature. To predict heat stress injury and develop improved prestress maintenance practices, an understanding of the seasonal variation in annual bluegrass heat tolerance and the influence of soil moisture on heat tolerance is crucial. Annual bluegrass growing in the field on a Drummer silty clay loam (fine silty...

This study was carried out to investigate the yield response of 2 soybean (Glycine max (L.) Merrill) cultivars to different planting dates and plant populations and to examine the relationships of seed yield with leaf area index (LAI) and total dry matter (TDM) during the vegetative and reproductive periods for planting dates, plant populations, and cultivars. Two soybean cultivars, A3127 (earl...

in order to determine of the proper sowing date of steckling (rootlet) and harvesting date of seed, an experiment was conducted in ardabil agricultural research station (alarough) in 2004- 05 growing season in split-plot in randomized complete block design arrangement with four replications. four different planting dates viz. 5th march, 20th march, 4th april and 19th april– were allocated to th...

This study was aimed to determine forage value of quinoa at the different sowing dates under semi-arid conditions. Research conducted according randomized complete blocks design with three replicates in Harran plain conditions 2016, Sanliurfa, Turkey. Q-52 Quinoa (Chenopodium Willd.) variety used as plant material. In 9 were such 15 February, 1 March, April, May, June and June. research height,...

This study was conducted to evaluate the effect of replacing corn grains with cull dates (CD) on the performance of growing goats kids. Twelve male kids aged 6 months with an average body weight 16.5 kg + 0.25 kg were placed in individual pens and fed with four levels of replacement of corn grains by CD (0, 50, 75 and 100%) during 90 days. Daily live-weight gain, dry matter intake and feed conv...
