soil and water salinity damage and decrease canola yield. however, plant yield should be increased using effective methods. this study aimed at investigating the effect of sulfure application fertilizers on canola yield. to this end, the experiment was conducted in split plot arrangement based on randomized complete blocks design with three replications at shavoor research station in south west...

The reaction of a recently synthesized dihydroboron species complexed with bis(phosphinimino)amide, LBH2 (), (L = [N(Ph2PN(2,4,6-Me3C6H2))2](-)) with 3 equivalents of BH2Cl·SMe2 or one equivalent of BCl3 affords the first stable monohydridoborenium ion, [LBH](+)[HBCl3](-) () that is stable without a weakly coordinating bulky anion. Compound can also be prepared directly by refluxing LH with 3 e...

this study was aimed to assess the effects of excess boron on 59 genetically divergent wheat accessions and to identify those with high and stable yields under a range of soil boron concentrations. the second aim was to test the applicability of a laboratory technique performed at juvenile stages of development in estimating field boron tolerance. the study comprised a control and three boron t...

introduction: boron (b) is an essential plant micronutrient whose soil availability is influenced by many soil factors.understanding the processes controling activity of boron (b) in the soil solution is important for soil fertility management. the reaction of adsorption and desorption of boron in soil determines the amount of boron that is available to plants. adsorption–desorption processes p...

Boron (B) is essential to growth at low concentrations and limits growth and yield when in excess. Little is known regarding plant response to excess B and salinity occurring simultaneously. In this study, two models of Leibig-Sprengel (LS) and Mitscherlich-Baule (MB), originally proposed to explain plant response to nutrients only, were modified to evaluate canola yield response to combined le...

introduction: sulfur is the key element for higher crops and plays an important role in the formation of proteins, vitamins, and enzymes. it is a constituent of amino acids such as cysteine and methionine, which act for the synthesis of other compounds containing reduced sulfur, such as chlorophyll and utilization of phosphorus and otheressential nutrients.deficiency of this nutrient in soil is...

Boron (B) is a non-metal micronutrient which is essential for plants growth and development. Formation of boron complex with cell wall matrix and phenolic compounds is a definite influence of boron in physiological process. It has been suggested that B-toxicity and deficiency may induce excess production of reactive oxygen species thereby promote defense responses by antioxidant enzymes or non-...
