In order to investigate the effect of micronutrients foliar application on seed yield and essential oil of black cumin, a field experiment was conducted based on Randomized Complete Block Design (RCBD) with three replications at the farmlocated in Naqadeh city, West Azerbaijan province, Iran, during 2015-2016 growing season. Treatments were separate application of Nano-Iron, Nano-Zinc and Nano-...
Micronutrients availability including that of Zn is critical for optimum growth of plants. Zinc availability in calcareous soils of Iran is relatively low due to the presence of a large amount of CaCO3 and high pH levels. Overapplication of phosphorus to soils may also cause P-induced Zn deficiency. The objective of this experiment was to evaluate the effect of phosphorus and zinc application o...
this study was conducted for evaluating the combined effect of soil moisture, phosphorus (p) and zinc (zn) levels on the growth attributes of potato (solanum tuberosum l. cv. agria). this investigation was arranged as a factorial experiment based on randomized complete blocks design with zn at three levels (0, 10 and 20mg zn per kg dry soil as zinc sulfate), p at three levels (0, 30 and 60mg pe...

although micronutrients effect on growth and yield of different plants has been intensively investigated, but there is limited information on its effect on grain yield and seed oil content of pot marigold) calendula officinalis l.). in order to investigate the effects of micronutrients (fe, zn and mn) spraying on yield and yield components and seed oil of pot marigold, a field experiment was co...
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
Two experiments were conducted under field and greenhouse conditions, to investigate the effect of herbal spraying chlormequat chloride (CCC) (0 and 2.5 g. L-1), soil incorporation of Zinc sulfate (Zn) at the three rates of 0, 25 and 50 kg ha-1, and pre-treatment of seeds with bio-fertilizer Nitroxin (Nit) in a randomized complete block design with a factorial arrangement and three replications...
sulfur (s) is an essential macronutrient influencing plant growth, nutrient efficiency, quality and health of agricultural crops. the purpose of this research was to study the effects of s rates and sources on growth and fruit quality of apple (malus domestica l.) trees of ‘golden delicious’ at west azerbaijan, iran. experiment was conducted during four seasons (2003-2007), using a factorial ra...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Mass production of medicinal and aromatic plants under hydroponic systems and especially in areas with saline soils is very important. An experiment was conducted to evaluate the interaction of salinity stress and foliar application of zinc (Zn) on hydroponically-grown basil (Ocimum basilicum L.). The factorial experiment was arranged as randomized complete blocks design, with two salinity leve...
