Mathematical simulation model is very suitable to understand insect dynamical systems. This system is nonlinear and it is hard to deal with by pure mathematical models only. It offers a possibility to recognize possible gaps in our knowledge. A simulation model of immature stages development of greenhouse whitefly Trialeurodes vaporariorum (westwood) population is presented. The parameters, var...

azospirillum is a well-studied genus of plant growth-promoting bacteria. phytohormone production by pgpr is considered as one of the effective factor to increase the tomato yield significantly. in order to study the effect of azospirillum inoculant on on growth characteristics and yields of tomato, three strain of azospirillum were isolated, identified, and purified from tehran suburb soils. to...

Wheat is one of the world's most favoured food sources, reaching millions of people on a daily basis. However, its production has climatic consequences. Fuel, inorganic fertilizers and pesticides used in wheat production emit greenhouse gases that can contribute negatively to climate change. It is unknown whether adopting alternative farming practices will increase crop yield while reducing car...

Soil mulching has advantages for horticultural crops, from both agronomic and phytosanitary points of view. The most common material used is polyethylene (PE); however, promising alternatives the circular economy exist, such as straw (ST) biodegradable biopolymers (BBs). effect three aforementioned mulches was evaluated compared to non-mulched soil in a Mediterranean greenhouse two years an org...

Tomato is a versatile vegetable that is consumed fresh as well as in the form of processed products. More recently, there has been renewed attention given to the antioxidant content of tomatoes because many epidemiological studies suggested that regular consumption of fruits and vegetables, including tomatoes, can play an important role in preventing cancer and cardiovascular problems. Approxim...
