Herbage yield of alfalfa (Medicago sativa L.) depends on forage management or environmental conditions that change C and N resource acquisition, and endogenous plants factors such as root organic reserves and number of active meristems. The aim of this work is to study the influence of two sowing dates in summer (12 July or 9 August), N fertilization (0 or 100 kg ha(-1)) and/or irrigation appli...

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...

We studied germination behaviors and persistence mechanism of wild Glehnia littoralis, a typical coastal species at temperate sandy coasts of the North Pacific Ocean, and tested the hypothesis that the coastal plants may have evolved special seeds adapting to the coasts, by which they recruit and persist easily, occupying the coasts as ideal habitats. In the Shandong Peninsula, China, we invest...

In order to evaluation of influence of sulphur fertilizer on grain yield and the some of physiological indices of canola, an split plot experiment based on randomized complete block design was conducted in Research Farm Islamic Azad University, Ardabil branch in 2007. Factors were: sulfur fertilizer at four levels (0 as control, 25, 50 and 75 kg S/ha) in the main plots and canola cultivars at t...

introduction: production and growth of plants in many parts of the world due to degradation and water scarcity have been limited and particularly, in recent decades, agriculture is faced with stress. in the most parts of iran, especially in the khorasan razavi province, drought is a fact and water is very important. due to melon cultivation in this province, and the conditions of quality and qu...

To study the effect of bacterial siderophore on the second cropping of maize (SC645) under drought stress conditions, a factorial experiment was arranged in a randomized complete block design with three replications. Two irrigation treatments (75 (I1: unstressed control) and 120 mm evaporation from Class-A pan (I2: delayed irrigation)) and two siderophore application treatments (S1: with and S2...

In the wild, seed dormancy promotes fitness by preventing germination before conditions are optimal for plant growth. During crop domestication, however, seed dormancy was selected against to ensure uniform germination upon sowing. Despite this, too little dormancy can be problematic, especially in cereal crops where it causes yield losses due to preharvest germination. Seed dormancy has long b...
