Calcium and potassium are essential nutrients that play a significant role in increasing yield, quality and postharvest properties of many fruits and vegetables. The role of these nutrients in improving quality and quantity of fleshy fruits is important and their interaction on plants such as cantaloupe is less understood. In this research the effects of calcium (0 and 3 g/L) and potassium (0, ...
A field experiment was carried out in the Research and Production Station, National Research Center, El-Nobaria during the season, 2009 to evaluate the effect of cobalt and different sources of phosphorus fertilizers on the growth, yield quantity and quality of tomato. Treatments can be arranged in descending order as follows: Mono super phosphate (MSP) > Triple super phosphate (TSP) > Rock pho...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
Kiwifruit requires a high quantity of nutrients that must be supplied through fertilization to obtain an optimum yield on a sustainable basis. This research was conducted to evaluate different fertilization methods including broadcast application (as control), deep placement of the fertilizer and fertigation, alone or in combination with foliar application and their effects on the yield, leaf m...
In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...
Background: Biostimulants are amino acids and organic components, which can play main role in the plant growth and dry matter accumulation. Objective: Determine the influence of foliar application of active amino acids on quality and quantity yield of Melissa officinalis L. Methods: This study was conducted in a research farm at the institute of medicinal plants on the base of randomized ...
optimal nutrition of grapevine is one of the most important factors that affect the quantity, quality and time of fruit ripening. to increase the quantity and quality of ‘askari’ cultivar, a factorial experiment in a randomized complete block design with three replications was conducted at shahrekord in 2010. treatments consisted of four levels of potassium sulfate fertilizer (zero, 300, 600 an...
An imbalanced nutrients status in the nutrient solution, i.e. poor nutrition of the plant, is often responsible for the low quantity and quality of strawberry fruit. The present study was conducted to investigate the effect of different ratios of potassium to magnesium (K/Mg) (T1, 2:1, T2, 4:1, T3, 6:1 and T4, 8:1) on fruit yield and quality of strawberry cv. Albion under hydroponic conditions....
Water stress is one of the most important factors limiting the growth and production of crops in arid and semi-arid regions. To evaluate the effect of mycorrhizal fungi species on the growth and yield (quantity and quality) of Onobrychis sativa under water deficit condition, a greenhouse factorial experiment based on completely randomized design (CRD) with three replications was conducted in 20...
