in the recent years application of allelopathic effects in weeds managment have attracted the attention of many researchers. to study the effects of water extracts and various amount of plants powder of sinapis, achillea, salvia, artemisia and wanut leaf on seed germination and seedling growth of bean, two separate factorial experiments were carried out in completely randomized design, with 3 a...

To integrate dynamic model based climate controlling in real-time with an environmental control computer a system integration interfacedBipsArchdwas developed. The three main objectives were: (1) to supply standard routines for communication with the environmental control computer. (2) to establish a set of databases to represent the current informational environment for the greenhouse. (3) to ...

temperature and humidity are two important parameters affecting the quality and quantity of greenhouse products so two double greenhouses were manufactured in 3.5, 40 and 11 m in height, length and width respectively in agricultural research center of jiroft and kahnooj to study these effects. both of greenhouses are similar in materials, final height, gutter height, covering and field operatio...

for investigating of o. aegyptiaca control in tomato with sulfosulfuron and glyphosate and evaluating the efficacy, dose and time of application, some studies were conducted in 2011 at aarhus university of denmark. at first, the efficacy of sulfosulfuron (0.029, 0.147, 0.735, 3.676 and 18.378 mg per lit) and glyphosate (0.023, 0.117, 0.587, 2.935 and 14.676 µl per lit) on egyptian broomrape see...

Tomato (Lycopersicon esculentum Mill) ‘Trust’ was grown on rockwool with nutrient solutions containing two levels of calcium (150 and 300 mg·L–1) in factorial combination with three levels of magnesium (20, 50, and 80 mg·L–1) in Winters 1997 and 1998, to investigate the effects of calcium and magnesium on growth, biomass partitioning, and fruit production. Plants grown at 20 mg·L–1 Mg started t...

To identify a post-plant nematicide to control root lesion nematode [RLN (Pratylenchus penetrans)] in red raspberry (Rubus idaeus), a number of nematicides was tested in soil-only and plant-based experiments. In soil-only experiments, soil naturally infested with RLN was drenched with the nematicides and nematode survival was assessed 7 and 14 days after treatment. Fosthiazate and oxamyl reduce...

The present study attempts to investigate the potential relationship between input energies, performance production of greenhouse basil, and greenhouse gases emitted from this product. The data were collected from 24 greenhouses using a questionnaire and verbal interaction with farmers. Results of the study showed that the total input energy and total output energy for basil production were 119...

introduction: farmers usually combine various herbicides with the aim of reducing the number of machinery passes across the field, preventing weed resistance to herbicides, and saving time and money. combination of herbicides is not only recommended for the management of herbicide resistance, but for increasing efficacy compare with a single herbicide application and expanding spectrum weed con...
