In this paper, the effect of irrigation water salinity levels on seed germination, dry matter weight of seedlings at eight-leave stage, and the salt tolerance of 8 rapeseed cultivars was investigated. Relative yield reduction in saline and non saline conditions, salt sensitivity index and Van Genuchten-Hoffman methods were used to determine the salt tolerance of the cultivars. Results showed th...
Understanding the physiological processes associated with high yield traits in modern cropvarieties is essential to further increase grain yield and improve nutrient management strategies.Field trials were conducted to study the effects of fertilization and variety on the grain yield ofrice (Oryza sativa L.) with two fertilizer levels and 18 modern varieties. The objectives were toevaluate yiel...
The present study was conducted to evaluate the effect of L-carnitine supplementation accompanied with two sources of fat supplemented diets (ω3 and ω6) on flushing period of Farahani ewes. 20 Farahani ewes were allocated in four different treatments which were as follow: 1) 2.5% dry matter intake ω3 source without L-carnitine 2) 2.5% dry matter intake ω6 source without L-carnitine 3) 2.5% dry ...
Due to the extensive area and biodiversity, rangelands contribute to meeting the nutritional requirements of grazing livestock; Therefore, a study was conducted to investigate the nutritional value of four range species including Malcolmia africana, Plantago lanceolata, Phlomis cancellata, and Klasea latifolia in the mountainous rangelands of Torbat-e Jam. The sampling of plants was randomly do...
BACKGROUND: Bio-fertilizers being essential components of organic farming play vital role in maintaining long term soil fertility and sustainability.OBJECTIVES: Study yield and growth indices of sorghum in response to consume chemical fertilizer and Nitroxin bio-fertilizer.METHODS: This research was conducted via split plot experime...
BACKGROUND: Mineral nutrition is one of the most important factors affecting plant growth and productivity, also growth analysis is a way to assess what events occurs during plant growth. OBJECTIVES: The goals of this study were to investigate the effect of different level of nitrogen fertilizer and zinc sulfate on growth indices of Green bean. <str...
In order to investigate the effect of sugarcane compost on consumption of nitrogenous fertilizers in corn fields, a research project was conducted according split plot experiment based on randomized complete block design with three replications along 2015 year. The main plot included different chemical nitrogenous fertilizer (Zero; control, 60 and 120 kg.ha-1 pure nitrogen from urea ...
abstract colchicum kotschyi boiss (colchicaceae) is one of the sixteen iranian native colchicum species, containing considerable amount of colchicine. to study the effect of different nutrient levels on corm yield and colchicine content of colchicum kotschyi boiss under open field soilless culture, an experiment was performed in a randomized complete design at the horticultural research station...
The NorFor system is a semi-mechanistic, which predicts nutrient supply and requirements for maintenance, milk production, growth and pregnancy in catlle. This research is aimed to evaluate the effects of grinding, pelleting and steam-flaking of corn grain on protein characteristic using NorFor model was tested according to completely randomized design. Degradability of dry matter and protei...
Auxin produced by plant growth-promoting bacteria (PGPR) in the wheat rhizosphere, can improve plant yield under water deficit stress condition. To investigate this issue, a completely randomized factorial design with three replications was conducted under greenhouse condition at the University of Maragheh, Eastern-Azarbayjan, Iran during 2019. Treatments were two types of growth-promoting bact...
