Given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. This study was conducted during 2012-2013 at the Research Center of Agricultural University of Tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. A...

INTRODUCTION In an extensive review of organic mulches applied on conventionally tilled (plow-disk) fields, Dutton (1957) concluded: 1) that organic mulches such ashay and straw often increasedboth yield and quality of Irish potato (Solanum tuberosum L.) and 2 ) that improved soil physical properties under the mulch, particularly lower soil temperatures and conservation of soil moisture, were r...

background and objectives: potato (solanum tuberosum l.) plant is one of leading agricultural products in the world. it is the fourth most cultivated food crop after wheat, rice and maize. planting density and weight of minituber are the factors influencing on the yield and yield components on seed tuber production in potato. plant density strongly affected yield, both by number and by weight a...

Potato grown for early or off-season production plays a crucial role in the economy of several areas in the Mediterranean countries. Irrigation is important for determining yield and earliness, thus a better investigation of plant response under various pedo-climatic conditions can help to improve resource use efficiency and farmer income. A two-year field research (2009-2010) was carried o...

Four bioagents i.e. yeast (Saccharomyces cerevisiae), Trichoderma viride, Bacillus subtilis, and Pseudomonas fluorescens in addition to humic acid, sulphated canola oil (sulphex 0.5%) and Paclobutrazol (PBZ) were applied to study their effect on disease incidence caused by Sclerotium rolfsii. Also, some vegetative parameters, tuber yield and enzymes activity of Jerusalem artichokes (Helianthus ...

this research was conducted at the shahrood agricultural research center in 1382 and 1383 to study the effect of alternate furrow irrigation on potato yield and its economic evaluation. the experimental design was a randomize complete block design and the treatments were: every furrow irrigation (efi), fixed alternate furrow irrigation (fafi), variable alternate furrow irrigation (vafi), fixed ...

The aim of the present study was to get somaclonal variants and induced mutants of potato for desirable characters with special emphasis on yield and yield components in two cultivars of potato viz., Desiree and Diamant. Inter-nodal explants from both the cultivars were incubated for 1420wks in callus inducing medium comprising MS salts supplemented with NAA (1.0mg/l) and BAP (0.5mg/l) for obta...

This study was performed in order to determine the distance of isolation for the seed potato production from ware potato in three regions of Ardabil, Namin and Nir. The experiment was carried out in a randomized complete block design (RCBD) with five distances (100, 200, 300, 400 and 500 meters from ware potato) and three replications with Super Elite (SE) class of Agria potato cultivar from wa...

Plant lipoxygenases (LOXs) are a functionally diverse class of dioxygenases implicated in physiological processes such as growth, senescence, and stress-related responses. LOXs incorporate oxygen into their fatty acid substrates and produce hydroperoxide fatty acids that are precursors of jasmonic acid and related compounds. Here, we report the involvement of the tuber-associated LOXs, designat...
