approximately 10-30% of tomatoes are wasted during processing. tomato pomace consists of crushed skin and seeds of tomatoes. seeds might be considered as a potential source of vegetable oil. the extracted oil is high in unsaturated fatty acids, namely linoleic acid. the extracted oil after purification or refining might be employed for consumption. the object of this study was to evaluate the e...

Aeroponic planting is proved to be the one of the most efficient growing environments for many vegetable crops. In this technique, plants are cultivated in absence of soil and the required nutrients are directly supplied to the roots through a fogging system. In modern sprayers, water is atomized by means of ultrasound waves. The aim of the present study was to investigate the effect of ultraso...

agroecology emphasizes the use of organic materials in agriculture. the organic acids are important sources of organic materials. in order to study the effect of different levels of humic acid on yield and yield components of corn (zea mays l.) an experiment was conducted at research station, faculty of agriculture, ferdowsi university of mashhad, iran, during 2009. the experiment was conducted...

to evaluate the anti-transpiration effect on yield and yield components of corn late yield 704 under drought stress experiment split factorial randomized complete block design with three replications in spring 2012 at the research station, kermanshah. and paclobutrazol treatments include salicylic acid, which is taking on two levels. based on the values determined in the following order foliar ...

abstract balanced nutrition and soil organic mater are among most important factors affecting yield and quality of grape (vitis vinifera cv.peykani). humic acid as an organic acid derived from humus and other organic sources, in accompany with zinc, and acetic acid can reduce deficiency symptoms in grape. to study the effects of zinc, humic acid and acetic acid on yield and yield components, an...

an experiment was conducted in order to evaluate the effects of humic acid spraying on  grain yield and yield components of wheat, in agricultural research and natural resources center of tehran province, in 2010-11. a split-plot layout within randomized complete block design with three replications were used. main plots were three irrigation treatments contains of normal irrigation, non-irriga...

humic acid, which has hormone- like activity , not only enhances plant growth and nutrients uptake but also improve stress tolerance. to determine the effect of humic acid on the yield and vegetative characteristics of tomato an experiment was conducted with tomato cv. `isabela` in 2008 in a plastic tunnel at the agriculture faculty, guilan university using randomized completely design with fou...
