controlled environment may be adopted for a rapid multiplication of a large number of potato seed tubers. the controlled environment prevents seed tuber degeneration which may occur under field conditions. the objective of this study was to introduce new mini-tuber production system with high multiplication rate and low production cost. to evaluate the performance of culture systems in terms of...

The aim of the present study was to investigate the effects of two locally produced microbiological products Trihodermins B-J and Vitmins on scale promotion and bulblet development in Lilium. Lily scales were given three treatments: untreated controls; Vitmins solution (10 ml L) and Vitmins solution (10 ml L) + Trihodermins B-J (dry powder form, at 10 g kg in the substrate). After treatment, sc...

in order to investigate the possibility of using organic fertilizers in tobacco floating nursery, an experiment was conducted at tobacco research institute of urmia in 2010. the experiment was done as factorial trail based on randomized complete block design (crbd) with four replications. the levels of first factor were disinfected poultry manure, disinfected pigeon manure, a complete fertilize...

ABSTRACT- To compare the effects of six types of non-living mulches (wheat straw, sawdust, coco peat, peat moss, transparent and black plastic) with metribuzin on yield and yield components of tomato cv "CH" and the weed control efficiency, a study was conducted in a randomized complete block design with three replications at School of Agriculture, Shiraz University in 2012. Plots without mulch...

Our study was to develop a rapid and successful method for promoting asymbiotic seed germination and growth and development of protocorm like bodies (PLBs) and subsequent plantlets of Phalaenopsis orchid. Four basal media i.e. Murashige and Skoog (MS), half strength MS (½MS), Knudson C (KC) and, Vacin and Went (VW) supplemented with coconut water and peptone were examined for their effectivenes...

The Cu(II) binding properties of Canadian Sphagnum peat moss, humic acid and humin extracted from the peat moss were investigated. Batch pH profile experiments indicated that the adsorption of Cu(II) is pH dependent. At pH 4.0 and 5.0 about 99% of the Cu(II) was bound by all three biomasses. Time-dependent experiments showed that the binding of Cu(II) is very rapid. The Cu(II) binding capacitie...

Purpose: Modification of natural sorbents to improve their sorption properties. Design: Microwave treatment effect on the properties peat, reindeer moss, moss and pine sawdust. Research findings: Short-term microwave has no moisture oil absorption by peat moss. On contrary, sawdust are improved, especially wood waste, i. e., capacity increases 41 %. The provides 11.4 17 % increase in relation p...
