The aim of the research was to determine field, greenhouse and seed bed performance of plantlets derived from in vitro propagated plantlets of three potato cultivars. Generally, higher values were obtained from the mid-early maturing cultivar Marabel, compare to other cultivars (early cultivar Velox and and mid-early cultivar Concorde) for tuber yield, tuber number and average tuber weight. For...

An experiment was conducted at the research field of Tuber Crop Research Centre (TCRC) of Bangladesh Agricultural Research Institute, Gazipur during the winter of 2006-2007 to determine the effects of cutting methods and seed size on the yield and profitability in potato (Solanum tuberosum L.). It was observed that the foliage coverage, plant height, stems/hill, number and weight of tubers/plan...

a factorial experiment based on a randomized complete block design with three replications was carried out in order to study the effects of tuber size, nitrogen fertilizer and harvest date on yield and yield components of potato. this experiment was conducted in a grower’s farm in uraki village located in chabahar city, in 2011. in this experiment, the treatments were two levels of tuber size (...

Pinellia ternate (Thunb.) Breit (Araceae) is a shade-tolerant perennial medicinal plant, but its optimum light intensity is not sufficiently known. Hence, the influence of light intensity on the physiological responses, growth and secondary metabolic products in P. ternata under four light conditions (15%, 25%, 45% and 100% of full sunlight) in a greenhouse were to be investigated. The results ...

Volunteer potatoes are difficult to control in onions and can greatly reduce onion growth and yield. Herbicides and cultivation were evaluated for control of simulated volunteer potatoes in onions in 1996 and 2000. Three interrow cultivations did not control potatoes in the onion row and the remaining plants reduced onion yield 50 and 73% compared with the hand-weeded checks. Three applications...

Effects of nitrogen on the leaf chlorophyll (chl), yield and yield attributing characters of potato as tuber number and mean tuber weight were studied. Correlation coefficients between the investigated characters were determined. Five nitrogen rates (0, 150, 200, 250 and 300 kg/ha) and four potato cultivars (Burren, Slaney, Anna and Emma) were used in the study. First, second, third class tuber...

The relative magnitude of general combining ability (gca) and specific combining ability (sca) effects in three generations (years), viz. Seedling (SG), first clonal generation (FCG) and second clonal generation (SCG) for tuber yield, tuber number, average tuber weight and tuber dry matter of potato in a line x tester mating design (10 × 4) was studied. There were marked differences in the gca ...
