evaluation of weed population and their interference on lentil varieties at different sowing date was investigated in a field experiment in khorramabad during 2005-06 growing season. the experimental design was a randomized complete block in factorial arrangement with 4 replications. the experiment had 3 factors including: planting date at three levels (autumn, winter, and spring) weed interfer...

in order to investigate the weed diversity and modeling light interception in sole and intercropping millet and bean an experiment was conducted as complete randomized block design with 4 treatments and 4 replications at the agricultural research station, ferdowsi university of mashhad, iran, during 2008. treatments included monocultures, intercropping of millet and bean and a control treatment...

Broomrape (Orobanche cernua L.) is an obligate root parasitic weed that significantly reduces the qualitative and yield attributes of tomatoes globally. The efficient management broomrape challenging because its complicated nature. Field trials were conducted to assess influence various irrigation scheduling control strategies on broomrape, presence, tomato productivity. experiment was with a r...

to assess the radiation use efficiency (rue) of different rice cultivars under transplanting (tp) and direct-sowing (ds) systems and scrutiny of weed effect, a split-plot factorial experiment was conducted based on a randomized complete block design with three replications in 2011 at haraz extension and technology development center in mahmoudabad city, mazandaran. the main plots were two plant...

abstract field experiment was conducted to evaluate the effects of sowing date, crop density, and weed interference on yield and yield components of chickpea in lorestan province during 2005-06. the experimental was a randomized complete block design by factorial arrangement with 4 replications. the experiment had 3 factors: sowing date at 2 levels (autumn, and winter), crop density at 3 levels...

Specific weed management consists on adjusting herbicide treatments depending on the zone infested and the type of weed. In this context, the discrimination between grasses (monocots) and broad-leaved weeds (dicots) is an important objective mainly because the two weed groups can be appropriately controlled by different specific herbicides. This work proposes a method of discrimination between ...

Fenugreek (Trigonella foenumgraecum) is both [1] herb (leaves) and a spice (seed) belonging to the family Fabaceae. Fenugreek leaves and seeds are used in the cuisine of India. Fenugreek also has [1] medicinal value. Fenugreek seeds are known [2] to reduce serum glucose and improve glucose tolerance and hence are prescribed to diabetic patients. In the recent past supplemental Chromium is being...

An experiment was conducted to assess the effect of dietary supplementation of garlic (Allium sativum) and fenugreek (Trigonella foenum-graecum L.) seed powder as herbal feed additives on growth performance, carcass characteristics and economics of feeding in broilers. A total of 320 day old broiler chicks of Cobb-400 strain were divided into four treatment groups with 4 replicates of 20 chicks...

in order to determine the role of plant leaf area in radiation distribution within the canopy and a better understanding of how crops and weeds intercept light a study of the complexity of plants is necessary. the  effect of intercropping on leaf area distribution and dry matter accumulation in corn, soybean and weeds canopy was studied in a  field experiment at a research field of tehran unive...
