supplementary irrigation is a key factor in dryland production of lentil (lens culinaris medik.). in order to study the effects of supplementary irrigation on phenological and morphological characters of three lentil (lens culinaris medik.) cultivars, a trial carried out as split block based on randomized complete block design with three replications at research field of agricultural college, f...

This study was conducted to determine the chemical composition, metabolizable energy, digestibility and ability of gas production of Poa trivialis. Samples was collected at three phenological stages including: vegetative growth, flowering and seedling on two different elevations of 1300 to 1500 m and 2000 to 1800 m asl in Neor and Hir region as the first and second sites, respectively. Testing ...

In this study, aerial parts of Lippia citriodora Kunth were harvested at three phenological stages (i.e. vegetative, full flowering and fruit set). The essential oil isolated by hydro distillation for 3 h using a Clevenger-type apparatus and the oil was analyzed by GC and GC-MS. The yields of oils (w/w%) in different stages was in the order of: full flowering (0.9%), vegetative (0.48%) and frui...

in dry region, root systems play a major roll in controlling plant growth and yield due to their importance in absorbtion of water and nutrients. in order to evaluate the morphological characteristics of root chickpea and obtaining proper morphological makers for screening drought resistant genotypes, four experiments were conducted in different phenological stages of growth including, seedling...

Crocidolomia pavonana ( binotalis) [F.] demonstrates oviposition peaks in the Þeld that we believe to be correlated with host plant phenology. In previous two-choice laboratory experiments, we found the highest relative proportion of oviposition on cabbage to correspond either to plant growth stages 7Ð8 wk or 9Ð11 wk old, depending on the alternate host plant with which it was presented. In cab...

Information on forage quality could help rangeland managers to select suitable grazing method to achieve higher animal performance without damage to vegetation. The aim of this study was to determine and compare the forage quality of S. yazdiana and S. tomentosa, which are the most important species of saline rangelands in Ardakan in Yazd province, Iran. These two species are grazed by goats an...

Vegetation is a climate modifier: It primary modifier, such as the Amazon rain forest, or secondary agricultural fields of Pannonian lowlands in Central Europe. At periods winter crop spring renewal and start orchard growing season, enhanced evapotranspiration shifts energy balance partitions from sensible toward latent heat flux. This surface flux alteration converges into boundary layer, it c...

cucumbers grown under open air conditions, encounters chilling damages, during cold seasons. plastic tunnels provide suitable heat environment for growing cucumber. the objective of this research was to evaluate cucumber phonological stages and leaf area expansion within three different plastic tunnel microclimates to moderate air temperature and air humidity. three microclimates including 1. c...

Phenology is a key trait of plants all species, as it determines their season and duration growth reproduction, well ability to capture variable resources. Understanding the phenology Elaeagnus multiflora Thunb. rare but promising fruit medicinal plant Ukraine, namely codification stages seasonal development, according international BBCH scale, important for evaluation breeding material develop...
