In order to evaluate the effect of potassium sulfate fertilizer and ascorbic acid application on yield and yield components and growth of quinoa (Chenopodium quinoa Willd.), a field experiment was carried out at 2018-2019 at Isfahan, central Iran. A factorial experiment based on a randomized complete block design with three replications was used. Experimental treatments were potassium sulfate i...
Water stress is the most important abiotic stress in crop production. Silicium (Si) is the second most abundant element in the soil with beneficial effects on plant tolerance to biotic and abiotic stresses. In order to evaluate the effect of this element in increasing tolerance to water deficit in wheat, a factorial experiment was conducted based on a completely randomized design with three rep...
abstract saturated water content is one of the important parameters which its measurement is necessary in estimation of soil water retention and unsaturated hydraulic conductivity curves. in several researches, saturated water content is assumed to be equal to soil total porosity. in some others, its value is estimated by pedotransfer functions using readily available parameters, such as bulk d...
Drought stress is a limiting factor for production in agriculture. In order to evaluate the impact of plant growth regulators, Salicylic acid and Paclobutrazol on growth and physiological traits of Sweet Basil (Ocimum basilicum) under drought stress condition, a factorial pot experiment based on Randomized complete design with 4 replication was carried out at research greenhouse of Mohaghegh Ar...
The present study was carried out during 2007, 2008 and 2009 on 6 olive cultivars to investigate the process of oil and dry matter accumulation in response to warm and dry conditions in Dallaho Olive Research Station of SarpoleZehab, Kermanshah province, Iran. Results showed that oil begins to accumulate in the fruit from July, increases gradually through August and reaches its maximum as the f...
the aim of the experiment was to determine the effect of different dry matter content and addition of silage inoculant on the ruminal protein degradability. alfalfa herbage was collected from two cuts and the fresh matter was sampled two times during each cut (with different dry matter content). during the preparation of experimental micro-silages, the chopped forage was treated with a microbia...
In the area with terminal heat and drought stress such as Gonbad, allocation of produced dry matter to reproductive organs is of great importance. In order to evaluate the effect of different temperature and moisture regimes on dry matter distribution and harvest index ofcanola an experiment wasconducted at Agricultural Research Station of Gonbad during 2005-2007. The experiment was a RCBD arra...
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...
in order to study dry matter accumulation in different developmental stages and photoassimilates remobilization in bread wheat genotypes, a field experiment was carried out using a split split plot design based on a randomized complete block design with three replications in torogh agricultural and natural resources research station (mashhad, iran) in 2006-2007 and 2007-2008. main plots were as...
