Cynara cardunculus var. scolymus L. is a herbaceous perennial plant that could be drought tolerant once established after the first year. To evaluate the effects of water stress on growth parametersand forage quality of this plant, a field experiment was conducted using a randomized complete block design with three replications in Isfahan, Iran during 2013-2015. Treatments wer...
The study was conducted to investigate the effect of nitrogen application on the yield contributing characteristics, biomass yield and nutritive values of cowpea forage. Five nitrogen levels viz: 0 (T0), 15 (T1), 20 (T2), 25 (T3) and 30 (T0) kg N/ha were applied in 20 plots in a Completely Randomized Design (CRD). The result showed that the application of nitrogen fertilizer had significant (P<...
Sainfoin in believed as an important forage crop regarding its suitable agronomical characteristics and feeding livestock. Evaluation of general combining ability is a critical preliminary stage before selection of suitable parent and production of synthetic varieties. Thirty six sainfoin landraces which have been collected from different parts of Iran were grown in 2000 in a randomized complet...
In order to investigate effect of nitrogen fertilizer on yield and quality of three forage sorghum cultivars under Guilan climatological conditions a field study was conducted in 2010 cropping season at Rasht. A randomized complete block design with factorial arrangement with three replications was used. Treatment consisted of four levels of nitrogen fertilizer (0, 50, 100 and 150 kg N ha-1 fro...
Forage age and maturity generally have a larger influence on forage quality than environmental factors. Plant environment, however, cause deviations in forage quality even when harvested at the same maturity. Temperature usually has greater influence on forage quality than other environmental factors. Although increasing temperature normally hastens maturity, the primary effect may be through i...
Plant growth promoting rhizobacteria (PGPR) have originally been defined as root-colonizing bacteria that cause either plant growth promotion or biological control of plant diseases. The mechanisms by which PGPR promote plant growth are not fully understood, but it is believed that the plant growth promoting rhizobacteria enhance plant growth and yield either by direct or indirect mechanisms. T...
Cultivation of legume species as the second crop in rotation with rice and using plant growth promoting bacteria can be a good approach to improve rice production sustainability. This experiment was carried out to evaluate the effect of plant growth promoting bacteria on accelerating vegetative growth of crimson clover (Alborz 1) and rice (Hashemi) yield in a rice-based cropping system. A facto...
the calcium status of lactating, non-lactating, and male sheep on farm in southwestern punjab, pakistan was studied. pasture and animal were sampled at the end of the first month of summer and winter. all samplings were carried out fortnightly. a mineral supplement was available to all animals throughout the year. plasma calcium in all animals was not affected by the physiologic state and gende...
Forage chicory is a productive forage resource for eastern North America; however, many soils in the region are acidic and deficient in P and might restrict the widespread use of forage chicory. There is no published information on response of forage chicory to P, or P acquisition strategies for morphologically different chicory cultivars. The literature suggests the following null hypothesis: ...
