The sorghum-sudangrass hybrid (Sorghum bicolor x S. sudanense) is an important forage crop. However, little is known about the genetic mechanisms related to forage yield and the 4 forage yield component traits in this forage crop. In this study, a linkage map was constructed with 124 assigned SSR markers using an F2 mapping population derived from the crossing of sorghum Tx623A and sudangrass S...

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...

this research was assigned to study the top crop yield potential and nutritive value of jerusalem artichoke (helianthus tuberosus), using a completely randomized designed with three treatments and four replications. the forage was cut at three growing stages where plant high, fresh and dry forage yield and leave/steam ratio were recorded. first and second cut were made when the plant heights we...

Dueto theactionofo-quinones formedviapolyphenoloxidase, conserved red clover (Trifolium pratense L.) contains abundant rumen undegradable protein (RUP), but inadequate rumen degradable protein (RDP) fordairy cattle. This studyexaminedhowforagemanagement influences RDP, RUP, crude protein (CP) and fiber fractions in red clover silage and dry matter (DM) yields during the first full production ye...

crop production in arid and semi arid environments has been affected by drought stress. forage production have important role on animal production in this area. in order to determine the effect of irrigation intervals on the yield and morphological characteristics of forage millet, sorghum and corn, an experiment was conducted in a split plot with a randomized complete block design with four re...

Red clover (Trifolium pratense) leaves contain high levels of polyphenol oxidase (PPO) activity and o-diphenol substrates. Wounding of leaves during harvest and ensiling results in browning of leaf tissues from activity of PPO on the o-diphenols. In association with browning, leaf proteins remain undegraded during ensiling, presumably due to PPO-generated o-quinone inhibition of leaf proteases....

Abstract Both from the environmental and economical perspective, reducing use of mineral nitrogen herbicides is one future challenges in cereal production. Growing winter cereals on perennial legume living mulch such as white clover ( Trifolium repens L.) or lucerne Medicago sativa several options to reduce need for fertilizer Given importance world, adopting this technique could greatly improv...

background and objectivesintercropping or simultaneous growing of two or more crops on the same piece of land has the potential of enhanced ecosystem productivity. in a cereal-legume intercropping system, an increase in cereal and a decrease in legume intercrop yield is reported. several indices such as land equivalent ratio (ler), relative crowding coefficient (k), competitive ratio (cr), aggr...
