Rangelands are the main source of forage production whose degradation is being accelerated due to improper utilities. Furthermore, re-vegetation of palatable plants like Vicia variabilis is more limited in overgrazed rangelands. The objective of this study was to improve degraded rangelands in Meleh-Kabud (Kermanshah, Iran) through planting Vicia variabilis. The research was conducted at experi...

Water oak is often used in afforestation projects in the Lower Mississippi Alluvial Valley, but its field performance is often poor due to low survival rates and severe top dieback immediately after planting. The poor physiological quality of planting stock may be a contributing factor to this transplanting problem. In this study, cold storage was investigated to increase dormancy status of see...

Abstract Performance of cowpea ( Vigna unguiculata L.) in two different planting seasons sandy soil was affected by base fertilizer application. Significantly, has responds to organic fertilizers. These treatments allow growth better. This research consisted phases, following the season i.e., II/October 2020 March 2021 and I/April September 2021. The first aimed study effectiveness three types ...

Commercial floriculture is an emerging profitable agro industry in the world with great demand of cut flowers but a constraint to regulate supply for longer duration markets. The off-season plucked get better price, as glut during peak season affects profits. This could be achieved by cultivating varieties over wide range planting times which demands evaluation varietal performance under differ...

Concern about climate change has evoked interest in the potential for urban vegetation to help reduce the levels of atmospheric carbon. This study applied computer simulations to try to quantify the modifying effects of existing vegetation on the indirect reduction of atmospheric carbon for two residential neighborhoods in north-west Chicago. The effects of shading, evapotranspiration, and wind...

To determine the nitrate pollution (water, soil, and tubers) in small (< 0.5 ha), medium (0.5- 1 ha) and large (> 1 ha) size of potato fields, this study was conducted in Fereidan region of Isfahan province during growing season of 2014-2015. For this purpose, the amounts of inputs and the tuber yield were recorded in each farm. Also, average nitrate-N concentration in irrigation water, soil an...
