Physiological responses of sunflower to water stress under different levels of zinc fertilizer

Physiological responses of two tomato (Lycopersicun esculentum M.) cultivars to Azomite fertilizer under drought stress.

This study was conducted in order to investigate the effect of drought stress and Azomite fertilizer on some physiological traits of two tomato (Lycopersicon esculentum M.) cultivars (izmir and Izabella). A randomized complete design with factorial arrangement with three replications was used. Treatments consisted of three levels of irrigation including FC (control), FC (mild drought stress), a...

Physiological responses of sesame (Sesamum indicum L.) to foliar application of boron and zinc under drought stress conditions

Micronutriens deficiency is prevalent in case of drought stress conditions, so complementary boron and zinc nutrition are important for crops to overcome drought stress. This study evaluated the effect of zinc and boron foliar application on physiological traits of sesame under different irrigation levels. The experiment was conducted as a split plot in a randomized complete block design with t...

DIFFERENT GROWTH RESPONSES OF THE AXIAL AND COTYLEDONARY TISSUES OF SUNFLOWER SEEDS TO C H UNDER WATER AND SALT STRESSES

Maize (Zea mays L.) Agro-Physiological Response to Potassium and Iron Fertilizer under Water Deficit Stress

This research was conducted to evaluate effect of potassium and iron fertilizers on agro-physiological traits affected different irrigation regime of corn in Shahryar (Tehran province, central of Iran) via a split-split plots arrangement based on randomized complete blocks design with three replications during 2015. The main plot included different irrigation regime (Normal irrigation and stop ...

Early Detection of Plant Physiological Responses to Different Levels of Water Stress Using Reflectance Spectroscopy

Early detection of water stress is critical for precision farming for improving crop productivity and fruit quality. To investigate varying rootstock and irrigation interactions in an open agricultural ecosystem, different irrigation treatments were implemented in a vineyard experimental site either: (i) nonirrigated (NIR); (ii) with full replacement of evapotranspiration (FIR); or (iii) interm...

Molecular and Physiological Responses of Sunflower (helianthus Annuus L.) to Pgpr and Sa under Salt Stress

This paper presents the efficacy of PGPR (Azospirillum and Pseudomonas) and its modulation by salicylic acid. Two hybrids of sunflower (Hysun and Parsun) were inoculated with Azospirillum spp. and Pseudomonas spp. prior to sowing. Salt stress (20 dSm) was applied 28 d after sowing followed by foliar spray of salicylic acid (100 μM) after 4 h of salt treatment. Azospirillum and Pseudomonas inocu...
