determining the best mixture of sorghum and fenugreek intercropping defines the best forage quality in medicinal forage production. this project was conducted to evaluate the effect of biological, chemical and integrated fertilizing systems on forage quantity and quality in sorghum and fenugreek intercropping. the experimental treatments were arranged as split plots based on randomized block de...

to evaluate the quantitative and qualitative of forage in intercropping of sorghum and chickling pea under limited irrigation systems, an experiment was conducted in research farm, college of agriculture, university of tehran, during 2009 and 2010. the treatments were arranged as split plots consisted of three levels of irrigation regimes including control (irrigation after 70mm evaporation fro...

to evaluate the effect of intercropping of sorghum and alfalfa on forage yield and on weed biomass production, different proportions of sorghum and alfalfa intercropping system comprised of 50% - 50%, 25% - 75% and 75%-25%, along with sole cultures of sorghum, and of alfalfa were arranged as split plots in time, while a complete plot design with three replications being used to analyze the data...

to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...

Conventional methods of weed control are weather dependent, costly and labour intensive. Indiscriminate use of chemicals for controlling weeds may pose environmental problems. Sorghum allelopathy is a new technique, which has been tested for controlling weeds of wheat (Triticum aestivum L.) as a substitute for chemical herbicides to reduce environmental pollution. Mature sorghum herbage contain...

Sunflower is an important industrial crop since it grown all over the world for oil production, while Johnsongrass (Sorghum halepense (L.) Pers.) characterized by great competitiveness and can severely impair plant growth productivity. Thus, a two-year field experiment was conducted to evaluate impact of control practices on growth, seed yield, content sunflower crop. The results indicated that...

Site-specific weed management requires sensing of the actual weed infestation levels in agricultural fields to adapt the management accordingly. However, sophisticated sensor systems are not yet in wider practical use, since they are not easily available for the farmers and their handling as well as the management practice requires additional efforts. A new sensor-based weed detection method is...
