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...

In order to study the effect of salicylic acid and selenium foliar application on physiological characteristics, yield and yield components of safflower (Carthamus tictorius L.) under drought stress conditions, an experiment was conducted as split plot based on randomized complete block design with three replications. The main factor included irrigation in three levels, complete irrigation duri...

Extended Abstract Introduction and Objective: Due to the lack of micronutrient elements and the urgent need for biofortification in important and strategic plants in the nutrition of human society such as wheat, it is necessary to evaluate any strategy to optimize the quality and production of this product. This has led researchers to investigate the effect of foliar application of zinc and ir...

In order to evaluate the effect of concentration and time of foliar spraying of nitrogen fertilizer as complementary of soil nutrition on dry matter remobilization and seed and oil yield of rapeseed (Hyola401), an experiment was conducted in complete randomized block design with 16 treatments and three replications in two years (2008-2010) in Rice Research Institute of Iran (Rasht). In this exp...

Drought stress is one of the most important restricting factors for plant yield in arid and semi-arid regions. Seaweed extract, as a biofertilizer, enhances plant resistance against abiotic stresses via accelerating seed germination, root growth enhancement and uptake of plant nutrients. The present research was carried out to investigate the effects of foliar spraying of Ascophyllum nodosum se...
