in order to study the effects of magnetic field, silver nano particles and micronutrient fertilizers on sugar beet, an experiment was conducted at razavi research and technology institute, mashhad, iran. experiment carried out with seven treatments based on randomized complete block design with three replications. treatments included (t1) magnetic field and silver nano particles + kemira fertil...

This study aimed at evaluating some quantitative and qualitative properties of potato as one of the main commercial products in Iran. To this end, a split plot experiment on the basis of randomized complete bloke design with silicone and iron was carried out in jiroft as one of the commercial area of planting potatoes. The main factor included different levels of silicon (0, 10, 20, 30 mM.l-1) ...

Abstract The objective of this work was to evaluate the agronomic responses 'BRS Vitória' grapevines under bio-fertigation with and without conventional soil fertilizer. A completely randomized design used, three treatments 18 replicates. were: CFI, fertilizer irrigation; BF+CF, fertilizer; BF, only bio-fertigation. following variables were evaluated: graft rootstock diameters; plant growth; nu...

Optimal plant growth is crucial in research experi ments as well as in nursery operations. Two major factors that influence plant growth are soil mix and fertilizer. Use of com mercial soil mixes would be desirable for smaller operations which often lack facilities for mixing and sterilization. Several commercial potting mixes were compared to the UC (Universi ty of California) mix for growing ...

Due to the growing population of Earth, problem providing food comes fore. Therefore, search for new, economically available sources trace elements crop production is relevant. One these potential blast-furnace sludge: highly dispersed metallurgical waste, industrial processing which difficult due its high zinc content. We studied effect sludge on rapeseed plants in laboratory, greenhouse, and ...
