Search for an adapted forage species for feed production under existing marginal lands and harsh conditions is needed to overcome sever feed shortage in Egypt. Sesbania, Sesbania aegyptiaca (Sesbania sesban, L) has shown potential for forage production and being included in grazing systems, especially on marginal lands and salt–affected soils. An experiment was conducted in the summer of 2004 a...
The present study aimed to evaluate the productivity of pearl millet (Pennisetum glaucum L.) genotypes select promising for fresh and dry forage yields its traits thirteen selected from forty eight genotypes. experiments grown in a randomized complete blocks design with three replications at Sids Agricultural Research Stations, 2021 2022 summer seasons.
 Studied showed highly significant d...
the study was carried out to examine the effects of urban sewage and nitrogen fertilizer levels on yield quantity and quality forage of sweet corn was evaluated in yasouj at 2009. the main experimental factor consisted of 5 irrigation levels including: common irrigation water without sewage effluent until the end of plant growth (i1), the first half of plant growth period with sewage effluent a...
grass pea (lathyrus sativus l.) has a high potential for forage production inboth rangelands and cultivated rainfed areas of iran. it is well adapted to semi-arid areas ofwest and north of country where annual rainfall is 250–350 mm. to study the seed and drymatter (dm) yield and agronomic traits, six genotypes of lathyrus sativus l. and twogenotypes of lathyrus inconspicuous l. were provided b...
To determine the appropriate proportion of oat mixed cropped with berseem clover under manure application levels, an experiment was carried out in the crop year 2015-2016; this study was carried out in Khuzestan Agricultural Sciences and Natural Resources University, as a split-plot design on the basis of RCBD with three replications. In this experiment, manure levels including: 0, 12, 24and 3...
in order to select and release of bastan a new cultivar of foxtail millet, after preliminary selections in small millet germplasm a research was carried during 1997-2003 in karaj, golestan and dezful. during these years production potential of 10 foxtail millet genotypes was determined in a randomized complete block design for 3 years. the different characteristics include, leaf size, stem diam...
Sainfoin in believed as an important forage crop regarding its suitable agronomical characteristics and feeding livestock. Evaluation of general combining ability is a critical preliminary stage before selection of suitable parent and production of synthetic varieties. Thirty six sainfoin landraces which have been collected from different parts of Iran were grown in 2000 in a randomized complet...
Mix cropping of alfalfa (Medicago sativa) and annual ryegrass (Lolium rigidum) may improve forage production in the rangeland and field conditions, especially in spring after the establishment year. In this study, the effects of different sowing rates of alfalfa and annual ryegrass seeds in the replacement and additive series of mix cropping were evaluated on forage yield in first year after th...
Regardless the crop production, range and livestock management is unlikely to be possible. Considering the range production is essential for efficient and effective range management. This study aims to investigate the relationship between the rate of forage production and the effects of climate variables. For this purpose, forage yield of four range species including Artemisia sieberi, Scar...
Cereal crop yield is determined by different yield components such as seed weight, seed number per spike and the tiller number and spikes. Negative correlations between these traits are often attributed to resource limitation. However, recent evidence suggests that the same genes or regulatory modules can regulate both inflorescence branching and tillering. It is therefore important to explore ...
