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, ...

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...

Research was initiated at the Texas Experimental Ranch by 1981 to quantify the effects of 2 livestock densities on forage quality in a rotational grazing (RG) treatment. Livestock densities evabmted were equivalent to 14 and 42-paddock RG treatments. Baseline data were collected in 1981 from 3 adjacent 30-ha paddocks in a 465_ha, M-paddock, ceil designed RG treatment stocked at a rate of 3.6 ha...

We assessed national scale changes in the forage plants of bumblebees in Britain, as a means of providing quantitative evidence for the likely principal cause of declines in bumblebee species. We quantified the relative value of native and long-established plant species as forage (nectar and pollen) resources for bumblebees by collating visitation data from 14 field sites across Britain. Twenti...

This research was conducted to investigate the effect of growth-promoting bacteria on yield and some traits of maize. This experiment was performed as a factorial randomized complete block design with three replications at research farm of Islamic Azad University, Izeh branch, Iran. The experimental factors included four strains of plant growth-promoting bacteria: Pseudomonas fluorescent 169 (B...

Forage sorghum is considered to be the most heat and drought resistant summer forage with a fairly high green forage yield. Forage sorghum is more economical to grow as compared to forage maize with fairly high economic returns. The total area under forages in 2012 in Punjab was 1.82 million hectares with green forage production of 38.8 million tons. The land area of Punjab under forage sorghum...
