In order to determine the most suitable cultivar and N level based on yield and silage value of forage sorghum, an experiment was conducted in summer 1995. The experiment was arranged in a split-plot design with four replications. Two levels of N (300, 500 Kg/ha urea) were the main plots and the subplots were three sorghum hybrids (Sugar graze, Super dan and Speed feed). Seeds were hand sown on...

introduction amount and vertical distribution of leaf area are essential for estimating interception and utilization of solar radiation of crop canopies and, consequently dry matter accumulation (valentinuz & tollenaar, 2006). vertical distribution of leaf area is leaf areas per horizontal layers, based on height (boedhram et al., 2001). above-ground biomass is one of the central traits in func...

In order to study the effects of weeding and plant density on forage yield of two sorghum cultivars, an experiment was conducted in 2011 at Bahonar University of Kerman Research field station. The experiment was designed as a randomized complete block with a factorial-split treatment arrangement and with three replications. Treatments were included four levels of weeding (whole season wedding, ...

the effect of different salinity levels (1.7, 5, 10, 15 and 20 ds.m-1) on yield and forage quality of two millet cultivars (nutrifeed and bastan) was investigated in this experiment. a factorial test based on randomized complete block design with three replications was conducted during 2010-11 growing season. the results showed that with increase in salinity, dry matter yield decreased. the hig...

Concentrations of selected macro minerals (Ca, P, Na, K, and Mg) were determined from coolseason annual grass pasture forages over four consecutive late fall-winter-spring grazing seasons (2001-2005). Forage samples were taken from eight experimental pastures used in beef cattle grazing trials. Two, 2-yr experiments were conducted; animal and pasture data were reported previously (Myer and Blou...
