Abstract In order to assessment of the relation among low temperature with (Fv/Fm, leaf chloropyll and caratenoied contents) of clover spp, an experiment was arranged as split plot in RCBD with four replications include plant date as main plot ( 15 and 29 Sep.) and clover spp as sub plot ( Persian spp with 7 cultivars, Berseem , Red and Crimson clover with 1 cultivar) at Seed and Plant Impro...
White clover is important to New Zealand pastoral farming yet uptake of new agronomically superior cultivars by farmers is slower than expected. Three main areas which explain why this is occurring are: 1. The need to demonstrate economic benefits due to superior agronomic performance of new cultivars to overcome barriers such as price and farmers satisfaction with existing products. 2. Farmers...
The objective of this study was to compare utilization of red clover (Trifolium pratense L.) and alfalfa (Medicago sativa L.) by lactating dairy cows. Red clover and alfalfa were harvested and conserved as silage at two maturities in 2 consecutive yr. Each year, diets containing experimental forages and supplemental grain were fed to 16 multiparous Holstein cows in early lactation in a replicat...
Red clover (Trifolium pretense) has wide adaptability to different soil and climatic conditions, and suitable digestibility of forage compared to the other clover species. New red clover cultivar, Nasim, was primarily selected from clover germplasm received from Food and Agriculture Organization (FAO), the United Nations, in Seed and Plant Improvement Institute, Karaj, Iran. Agronomic and yield...
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...
To evaluate forage production and land equivalent ratio (LER) in additive and replacement intercropping systems of forage sorghum and berseem clover, a field experiment was conducted using randomized complete block design with eight treatments and three replications at the research field station of Seed and Plant Improvement Institute, Karaj, Iran, in 2016-17 and 2017-18 growing seasons. The ex...

Optimal fertilization of clover-grass fields relies on knowledge of the clover and grass fractions. This study shows how knowledge can be obtained by analyzing images collected in fields automatically. A fully convolutional neural network was trained to create a pixel-wise classification of clover, grass, and weeds in red, green, and blue (RGB) images of clover-grass mixtures. The estimated clo...
Background and Objective: Lead is a dangerous heavy metal for human health. This research was conducted to study the potential of a new Iranian corn (Maxima CV.) and white clover in monoculture and mixed culture for phytoremediation of Pb in a Pb polluted soil. Materials and Methods: The experimental treatments consisted of corn and white clover in a mixed culture (with 10 and 20 plant density...
Groups of six to nine Merino Summary lambs were weaned in September (May drop) and December (September drop) on to three types of irrigated perennial pastureperennial ryegrass (Lolium perenne), Ladino white clover (Trifolium repens) and lucerne (Medicago sativa), and one irrigated annual pasture-subterranean clover ( Trifolium subterraneum) . The weight gain of the weaners on white clover was s...
