Potatoes (Solanum tuberosum) were grown in a fine sandy loam soil in southern Manitoba in a three-year field study comparing four water management treatments: No Drainage with No Irrigation (NDNI), No Drainage with Overhead Irrigation (NDIR), Free Drainage with Overhead Irrigation (FDIR), and Controlled Drainage with Subirrigation (CDSI). The objectives of the study were (i) to evaluate the effect of the four treatments on yield and quality of potatoes, (ii) to evaluate the effect of water management on the environment, (iii) to estimate the shallow groundwater contribution to potato water req

MH is marketed in a formulation called `Fazor' and was introduced to the United Kingdom under PSPS (Pesticide Safety Precaution Scheme) in 1985. It is targeted at sprout suppression of ware tubers in store with the added benefits of increased marketable yield and reduced groundkeepers. Two field trials were conducted to investigate the sprout inhibition of MH and its effect on yield. Both field trials used a popular ware seed (c

Field, greenhouse, and laboratory experiments were conducted in 2014 and 2015 to evaluate effects of glyphosate drift on ?Red Norland? potato (Solanum tuberosum L.) grown for commercial and seed industries. Glyphosate drift was simulated by applying sub-lethal doses during the growth stages of tuber initiation (TI), early tuber bulking (EB), and late tuber bulking (LB). Sub-lethal glyphosate doses applied to mother plants had the greatest effect on daughter tubers during TI, resulting in high tuber sets and increased unmarketable tubers.

A linear-log model to predict yield loss due to metribuzin injury was established by Love et. al. in 1993.

Metribuzin was applied (1.12 a.i./ha) when potato plants were 20-30 cm tall at Inkster, ND. The model did not accurately predict yield loss in 2016 but performed better in 2017. Foliar injury was more correlated with yield reduction than relative plant height. Results also indicated that new models that used foliar injury at 21 days after treatment (DAT) data and at 7

Salinity problems seriously affect agricultural production by reducing crop yield and arable land. The evaluation of potato genotypes (Solanum spp.) for their salinity (NaCl) tolerance in conventional field trials is time consuming and labour intensive. The results are often confounded by many field and environmental variations. In vitro bioassays can overcome some of these difficulties by providing faster, more convenient and dependable methods for screening and selection of salt tolerant potato genotypes.

Potato cyst nematodes, PCN, cause major yield loss in commercial potato production. One of the mechanisms of yield loss cited is a reduction in the uptake of the major nutrients nitrogen (N), phosphorus (P) and potassium (K). For the work described in this thesis, it was hypothesised that nutrient application via the foliar route could by-pass the PCN-damaged plant root system, ameliorate the PCN-induced nutrient deficits and increase plant yield and tolerance of PCN attack. None of the three nutrients investigated (N, P, K) was individually shown to limit plant growth or yield of PCN-infected

Management of potato cyst nematodes (PCN) has become more challenging due to nematicide restrictions. This has led to research into alternative control methods such as biofumigation. Biofumigation exploits the release of toxic isothiocyanates (ITCs) from glucosinolate (GSL) hydrolysis during the breakdown of Brassicaceae plant tissue. The type and concentration of ITCs released varies between plant species. Biofumigation and ITCs have been shown to control soil-borne pathogens however no single ITC achieves broad-range control.
