relation is undesirable, as is the case with NDF and forage yield. The consequences, resolution, and/or amelioSelection for reduced neutral detergent fiber (NDF) concentration ration of these various factors in agricultural crops are has been used as a mechanism of improving intake potential of perendramatically different. nial grasses by ruminant livestock. However, reduced NDF concentration i...

Plant biodiversity theory suggests that increased plant species diversity contributes to the stability of ecosystems. In managed grasslands, such as pastures, greater stability of herbage production would be beneficial. In this retrospective study, I used data from three reports from the 1930s, 1940s, and 1960s to determine whether increasing mixture complexity contributed to yield stability wi...

Forage yield, nutritive value, and stand persistence are key metrics in alfalfa (Medicago sativa L.) management. The combination of cultivar improvement, longer growing seasons the Midwest, trends shorter rotations offer opportunity to reevaluate effects increasing cutting frequency (CF) on these metrics. We evaluated forage milk production, eight entries with fall dormancy (FD) ranging from tw...

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...

The effects of exogenous proteolytic enzyme (EPE) on intake, digestibility, ruminal fermentation, and lactational performance were determined using 8 lactating Holstein cows in a double 4 x4 Latin square experiment with a 2 x2 factorial arrangement of treatments. Diets based on barley silage and alfalfa hay as the forage sources were formulated to maintain different forage to concentrate ratios...

This study was carried out in the 2018-19 vegetation period to determine appropriate mixture ratios of forage pea (Pisum sativum L.) and rye (Secale cereale under rainfed conditions Kırşehir province, Turkey. The layout experiment randomized blocks with three replications treatments were pure rye, four different mixtures (20% FP + 80% R, 40% 60% P, 20% R). highest green yield (2395.1 kg da-1), ...

In order to study the effect of various amounts of nitrogen (N) and Iranian natural zeolite on the quantitative and qualitative forage yield of winter canola (Brassica napus L.) in light soil, a field experiment was conducted on research farm of Tarbiat Modares University, Tehran, during 2006-2007. Treatments were arranged in the form of RCBD with 3 replications. The experimental treatments wer...
