The experiment was carried out to study the impact of chilling and night break on the flowering of ornamental plants in their off-season period. Larsenianthus careyanus (Benth.) W.J. Kress & Mood is a wild potential ornamental ginger naturally growing in the evergreen forest of North Eastern states of India was selected for the current study. The rhizomes were collected and stored at 15oC for 8...

This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...

The aim of this study was to investigate the climate change impacts on some factors affecting rainfed wheat growth such as effective rainfall, planting date and length of growing season in four stations located in Chaharmahal and Bakhtiari province. Firstly, it is necessary to predict future (2046-2065) climatic conditions. For this purpose, the output of HADCM3 general circulation model was us...

Relationships between abiotic (soil temperature and number of freeze-thaw cycles) or biotic factors (chemical elements, microbial biomass, extracellular enzymes, and decomposer communities in litter) and litter decomposition rates were investigated over two years in subalpine forests close to the Qinghai-Tibet Plateau in China. Litterbags with senescent birch, fir, and spruce leaves were placed...

BACKGROUND Cutaneous leishmaniasis is a major health problem in Iran in spite of implementation of control program. This infectious disease caused morbidity in less than 27000 people in 2010. This study was set to determine some ecological aspects of sand flies in Fasa district, Fars Province, southern Iran during 2011-2012. METHODS A total of 4792 sand flies were captured by means of sticky ...

the seasonal abundance patterns of the cotton aphid, aphis gossypii glover, in cotton fields at gorgan in northern iran were studied during two growing seasons of 2002 and 2003. the spatial distribution of different developmental stages and morphs of the aphid was described by fitting data to poisson (random) and negative binomial (aggregated) dis-tributions, and calculating the dispersion indi...

The purpose of this study was to measure daily and seasonal evapotranspiration and daily crop coefficient of two common varieties of sunflower (Sirna and Euroflor) via drip-tape irrigation system. For this purpose, the sunflower water use was determined by daily monitoring of soil moisture at the depths of 10, 20, 30, 40 and 60 cm, and the crop evapotranspiration (ETC) was measured using volume...

in order to study yield and yield components of fennel (foeniculum vulgare mill) – fenugreek (trigonella foenum-graecum l.) in different patterns of intercropping and sole cropping, an experiment with use replacement and additive intercropping based on randomized complete block design with three replications was conducted at the research station of faculty of agriculture, zanjan university, ira...
