Dr. Ali Mokhtassi-Bidgoli was born in Kashan, Isfahan province, Iran on September 9, 1980. He passed his primary, secondary and high school education in Kashan, then moved to Tehran in 1998. He obtained all his undergraduate and postgraduate degrees in agronomy at various universities in Tehran. He defended his Ph.D. dissertation on competition between cereals, especially wheat and weeds, especially concerning the population dynamics model of flixweed in Tarbiat Modares University (Tehran). He also studied on weeds population dynamics over a six-month sabbatical leave in Spain, in collaboration with Professor Jose Luis González, and published a number of international papers on this subject. He is officially employed as Assistant Professor in Department of Agronomy, Faculty of Agriculture, Tarbiat Modares University, Tehran, from late 2013. He is an ecophysiologist of the crops and weeds, and is active in the field of weed management in fields and gardens, crop management with an emphasis on organic farming, as well as modeling and simulating the growth, germination, population dynamics, and climate change. In fact, he is interested in finding approaches to reduce the use of herbicides, as he emphasized in a lecture given at the Imperial College of London. He also studies on the new and neglected forage plants with an emphasis on adaptive
Introduction: Legumes are the most important source of vegetable protein supply. Bean produces seeds contain 25-22 percent protein and high nutritional value for human and also is a major source of supply protein in most modern societies (Rastgar, 2005). Today protein deficiency is one of the acute nutritional problems in the diet of millions in developing countries. Bean ranks third after pea and lentil in Iran as one of the developing countries with dry and semi-arid climate (Ghanbari et al., 2018). Weeds are controlled by hand as an earliest means, and by airplanes, chemical pesticides, hormones and viruses as the most complete tools (Ghanbari et al. 2013). It has been proved in the research that weed control treatments especially hand w
This study was conducted to investigate the effect of bio-fertilizers application on reducing the effects of water deficit on Pearl Millet under field conditions. The experiment was carried out as a factorial experiment based on randomized complete block design with three replications in selected farms under Lahijan Agricultural Jihad (Kolashtajan Agricultural Extension Office) and Agronomy Department of Tarbiat Modares University in year of 2018-2019. Treatments included three levels of stress include irrigation times (15 (control), 30 (moderate stress) and 45 (severe stress) percent depletion of available soil moisture and four levels of bio-fertilizer (control, nitroxin, BARVAR phosphate-2, nitroxin + BARVAR phosphate-2). The results sho
Having increased the temperature of different regions, global climate change can affect plants’ growth and development. This study aimed to explore the effects of high temperature on sugar beet (Beta vu-lgaris L.) performance at seedling stage (6–8 leaf stage) in two climatic areas of Iran, Karaj and Moghan, with different relative humidity (RH). Eight sugar beet genotypes, S1-92521, SB26, SHR. 02. P4, OT 607, S1‑92685, S1-92615, SB33-H-1 and 31714, were sown in both sites at two dates, April and July as control and high temperature stress treatments, respectively. Maximal quantum yield of PSII photochemistry in dark (F v/F m) decreased by high temperature in both sites, with genotypes S1-92521 and OT 607 showing the highest value in
Salinity stress is one of the main limiting factors of medicinal plant growth and may affect their characteristics and chemical composition. In order to evaluate the response of different species of Iranian mint to salinity stress, an experiment was designed in greenhouse conditions. In this experiment, six Iranian mint species were cultivated in pots under different salinity stress including 0, 2.5, 5, and 7.5 dS/m. The chlorophyll indices (a, b, total, and a/b ratio), carotenoids, total anthocyanin, total phenolic and flavonoid content, antioxidant activity, dry matter yield, and essential oil content were measured in two different harvest stages. Salinity stress affected various measured traits. The results showed that despite the negat
Sustainable management approaches should be considered to meet gaps between soybean N demand and biological N fixation in poor nutrient soils. Field studies were laid out in 2015 and 2016 to determine the effect of integrated fertilizer systems and zeolite application on two cultivars of soybean. The experiment design was randomized complete block design with factorial arrangement of treatments and three replications. Treatments comprised of two soybean cultivars (C) (M7 and M9), five fertilization systems (F1, 100% sheep manure; F2, 100% urea; F3, 50%, urea + 50% sheep manure; F4, 75% urea + 25% sheep manure and F5, 25% urea + 75% sheep manure), and four zeolite rates (Z1: 0?Mg ha−1 zeolite application (control) Z2: 4?Mg ha−1, Z3: 8?Mg
To study the effects of foliar application of putrescine (distilled water (0), 0.75, 1.5, and 2.25 mM) and water de cit stress (20%, 40%, 60%, and 80% available soil water depletion (ASWD)) on the physiological, biochemical, and molecular attributes of sage, a factorial experiment was performed in a completely randomized design with three replications in the growth chamber. The results of qRT-PCR analysis showed that putrescine concentration, irrigation regime, and the two-way interaction between irrigation regime and putrescine concentration signi cantly in uenced cineole synthase, sabinene synthase, and bornyl diphosphate synthase relative expression. The highest concentration of 1, 8-cineole, camphor, αthujone, β-thujone, cineole synth
One of the greatest challenges in recent years is providing enough food to feed the increasing world population, while available freshwater resources become limited. However, effective fertilizer management has also a fundamental role to improve yield quality and quantity. A field experiment was conducted over 2 years, using a split-plot arrangement in a randomized complete block design. The experiments had three water deficit severity treatments: 25%(control), 40%(mild stress), and 55%(severe stress) depletion from the available water. The subplot division consisted of six fertilizer treatments; FR 1: unfertilized (control), FR 2: 140 kg ha− 1 urea; FR 3: 105 kg ha− 1 urea+ 3.3 ton ha− 1 vermicompost; FR 4: 70 kg ha− 1 urea+ 6.6 to
