盐害是制约全世界作物生长的主要非生物胁迫之一,全球有6%土地和20%灌溉用地受到盐害影响,严重制约了农作物生长发育和产量。水稻作为全球主要粮食作物之一,对盐胁迫敏感。盐胁迫条件下,水稻种子萌发和幼苗形态建成显著受抑制,严重制约了我国水稻直播的推广和盐碱地区耕地利用。因此,挖掘鉴定控制水稻种子萌发的关键基因,阐明其在盐胁迫条件下调控种子活力的分子机制,对培育适合盐碱地生长的种子高活力耐盐水稻品种和保...
Potato yields and infestation by P. infestans are related to the supply of potassium. Potassium was applied as soil fertilisation combined with split foliar applications or only as split foliar treat...
We compared the effects of forest fertilization with wood ash and potassium (K) sulphate on growth and mycorrhizal colonization of fine roots and on other soil microorganisms in Norway spruce (Picea a...
Allometric coefficients for dry matter, calcium, phosphorus, magnesium, sodium, and potassium in relation to body weight were 1.091, 1.427, 1.383, 1.284, 0.843, and 1.097 for SG chickens and 1.075, ...
The aim of this 3 × 3 factorial experiment on broilers was to investigate the effect of different dietary levels of potassium and chloride on chicken performance, carcass composition and dry matter co...
Zeolite and vermicompost applications to soil may improve K fertility of soils. For this purpose, these materials were added to five representative calcareous soils collected from southern Iran. The t...
Amounts of potassium (K) fixed in soil fractions of 10 calcareous soils of southern Iran were measured to evaluate the contributions of different soil size fractions to K fixation. Soil particles were...
Ammonium and potassium thiosulfate are used commercially or experimentally as flower thinners because they are considered user, environment and consumer safe. The thinning trials were conducted in 2...
Salinity either of soil or of irrigation water causes disturbance in plant growth and nutrient balance and reduces crop yields. The effects of NaCl salinity and/or calcium or potassium level on the pl...
To break dormancy and increase the germination of Prunus avium L. (mazzard cherry) seeds, various methods were tested including the removal of the seed coat after cold moist stratification and treatme...
The response of the peach cvs. Springtime and Redhaven to nitrogen, phosphorus, potassium fertilizers and manure is reported. The research was conducted during a period of 10 years. The following fert...
Irrigation with high salinity water influences plant growth, production of photosynthetic pigments and total phenols, leading to reduction in crop yield and quality. The objective of this study was to...
Response of Green Bean to Fertilization with Potassium and Magnesium
Field experiments were conducted during the two successive spring seasons of 2008 and 2009 in the International Potato Center (ICP), Agriculture Research Center (ARC), Kafr El-Zayat, El- Gharbia Gove...
The current research was conducted to determine the effects of different potassium (K) and iron (Fe) rates on the growth and some micro nutrient uptake of maize. For this purpose, five K (1, 2, 4, 6 a...
