A field investigation was conducted during two kharif seasons of 2020-21 and 2021-2022 at Agriculture Research Farm, Rabindranath Tagore University, Raisen, Madhya Pradesh, India, to evaluate the effect different irrigation scheduling nutrient management practices on yield economics wheat crop in split-plot design with three replications. The level N0 - No irrigation, N1- One Irrigation CRI (cr...
water is the most important factor for agriculture development in iran. accordingly the optimal consumptione of water is very important. using pressurized irrigation system is one of the methods to improve agricultural water management. the objecttives of this research were to compare two irrigation methods of furrow and trickle irrigation systems impacts on quantity and quality characters of s...
damage caused by water shortages leads to physiological and biochemical changes in metabolism of plants and make them predispose to attack by pests and diseases and reduce the quality of the crops. in order to evaluate the effect of supplemental irrigation on safflower fly (a. helianthi) population of safflower cultivars, an experiment conducted as a split plot based on randomized complete bloc...
Some of the field crops are severely affected by the Fusarium foot and root-rot in the west of Iran, Hamadan. Pathogenic Fusarium species are potentially severe destructive diseases and could be a major limiting factor for the cereals and potato production in this province. The purpose of this study was to determine the possible effect of soil solarization on the population dynamics of Fusarium...
In order to assess the effect of drought stress and various levels of potassium on solutes accumulation and chlorophyll of canola and Indian mustard, a field experiment was conducted in a factorial design based on randomized complete block design with three replications including three irrigation regimes (I1=irrigation after 50% depletion of soil water(control),I2 =irrigation after 70% water de...
ABSTRACT- Despite the benefits of herbicides, their persistence in soil can harm other plants in next rotations and contaminate ground water. The main purpose of this research is to simulate 2,4-dichlorophenoxyaceticacid(2,4-D) movement in silty clay loam soil using HYDRUS-1D model in a corn root zone. The maximum contaminant level goal, MCLG, of 2,4-D in water resources is 10 ppb. The 3.5 kg a...
abstract cumin (cuminum cyminum) is one of the most important medicinal plants in iranian dry region. in order to study the effects of irrigation times and salinity stress on yield and yield components of cumin, an experiment was conducted at the research farm ferdowsi university of mashhad in 2009. factors including irrigation times (1: one time irrigation, 2: two times irrigation 3: three tim...
introduction in agricultural ecosystems, organic fertilizers play an important role in producing sustainable agricultural production. considering this sajjadi nik et al (2011) reported that with increasing of vermicompost inoculation with nitroxin biofertilizer, capsule number per sesame plant increased, so that the most of capsule number per plant (124.7) was observed in 10 t/h vermicompost wi...
abstract different strategies are existed for adjusting with water shortage, of which the strategy of suitable policies adoption by determining optimum production function can be mentioned. water shortage and quality degradation of soil and water resources is one of main factors of production reduction. therefore, this study was carried out for determination of tomato sensitivity coefficients a...
water scarcity in arid and semi-arid climate of iran has made deficit irrigation as a strategy for optimal water use and conservation in agricultural sector. this study aimed at evaluating the effects of water-deficit stress and n fertilizer levels on sugar beet performance. the study was conducted in split block design based on randomized complete block design arrangement. the row factor consi...
