“…Above-average rainfall in 2000 no doubt contributed to the higher yields, larger fruit size and lower percent soluble solids compared to the dry years (1999 and 2001). Tan and Dhanvantari (1985) and Tan (1995) reported rainfall distribution patterns affected yield and showed that irrigation markedly increased total and marketable yields in dry years. Tan (1995) also reported a reduction in percent soluble solids from irrigation.…”

, T. 2002. Effects of row arrangement and plant density on yield and quality of early, smallvined processing tomatoes. Can. J. Plant Sci. 82: 765-770. Early processing tomato (Lycopersicon esculentum Mill.) cv. H9230 and N1045 were field grown with three row arrangements and two plant population densities in 1999, 2000 and 2001 to investigate their effects on fruit yield, quality, and foliar and fruit diseases. An equidistant single row arrangement (75/75 cm) resulted in similar or higher yield compared with the two less-even twin row arrangements (60/90 cm and 40/110 cm) over the 3 yr. The equidistant single row arrangement (75/75 cm) and wide twin row arrangement (60/90 cm) had reduced foliar and fruit diseases in a wet year (2000). However, the incidence of blossom-end rot was greater in the equidistant single row arrangement in a dry year (2001). Increasing the plant density from 33 300 to 40 400 plants ha -1 by reducing the plant spacing within the row from 40 to 33 cm increased the yield by 3-5 t ha -1 . Row arrangement or plant density did not affect fruit size or soluble solids. Fruit size and soluble solids of H9230 were consistently greater than those of N1045 in all 3 yr. For production of early, small-vined processing tomatoes in southwestern Ontario, an equidistant single row arrangement with a plant density of 40 000 plants ha -1 is suggested. (2000). Toutefois, la nécrose apicale était plus fréquente dans la culture sur rang à espacement équidistant lors d'une année sèche (2001). Lorsqu'on change la densité de peuplement de 33 000 à 40 400 plants par hectare en réduisant l'écartement des plants de 40 à 33 cm, le rendement augmente de 3 à 5 tonnes par hectare. Ni la disposition des rangs, ni la densité des plants n'affectent le calibre des fruits et la concentration de solides solubles. H9230 a toujours donné des fruits de plus gros calibre, plus riches en solides solubles, que N1045 les trois années de l'étude. Pour produire des tomates de transformation hâtives sur petite vigne dans le sud-ouest de l'Ontario, les auteurs préconisent la culture sur un rang à espacement équidistant à la densité de 40 000 plants par hectare.

“…Akemo et al (2000) also reported lower yields in dry years compared to a year with more rainfall. Numerous studies have shown that tomato responds to irrigation with higher yields (Tan and Dhanvantari 1985;Sanders et al 1989;Tan 1995). An optimized combination of fertilizer N and irrigation needs to be developed.…”

, X. 2004. Effects of nitrogen fertilization on fruit yield and quality of processing tomatoes. Can. J. Plant Sci. 84: 865-871. Four processing tomato (Lycopersicon esculentum Mill.) cultivars (CC337, H9230, H9492 and H9553) were field-grown in southwestern Ontario using five N fertilization rates in each of 4 yr (0, 50, 100, 150 and 200 kg N ha -1 in 1999 and 0, 100, 150, 200 and 250 kg N ha -1 in 2000, 2001 and 2002). Total fruit yield increased linearly as N rate was increased except in 2001, which was a dry year. Responses of marketable yield to fertilizer N rate were dependent on cultivar and the year. In years when sufficient soil water was available, N fertilizer rates of 200 kg ha -1 or higher were required to produce the maximum marketable yield for the four cultivars. In the dryer years, the response to fertilizer N rate was cultivar dependent, and the application of 150 to 200 kg N ha -1 was sufficient to maximize marketable yield. Fertilizer N above the rate required for maximum marketable yield increased green fruit yield at harvest. Nitrogen rate did not affect the soluble solids (SS) content, firmness, size or colour of marketable fruit. Differences in yield and fruit quality were noted among cultivars. H9553 was the highest-yielding cultivar. H9230 had the largest fruit size. CC337 generally had the best red fruit colour and the lowest percent SS. H9492 generally had the highest percent SS. To attain maximum marketable yields, it appears that N rates should be adjusted based on cultivars, anticipated rainfall levels and availability of irrigation. Au-dessus du taux nécessaire pour atteindre le meilleur rendement, les engrais N accroissent le nombre de fruits verts à la cueillette. Le taux d'application d'engrais N n'agit pas sur la teneur en solides solubles (SS), la fermeté, le calibre ni la couleur des fruits commercialisables. On a relevé certaines variations dans le rendement et la qualité des fruits des cultivars. H9553 donne le meilleur rendement et H9230, les fruits les plus gros. En général, les fruits de CC337 ont le plus beau rouge et la plus faible proportion de SS. Enfin, H9492 donne habituellement la plus forte concentration de SS. Pour atteindre le rendement maximal de fruits commercialisables, on devrait modifier le taux d'application des engrais N en fonction du cultivar, en tenant compte des précipitations prévues et de la capacité d'irriguer.

“…Processing tomato is one of the most water‐demanding crops, such that water management plays an important role in tomato yield (Patanè and Cosentino, 2010). Irrigation has been widely practiced in southwestern Ontario, Canada, due to the shortage of rainfall during tomato growing seasons (Tan, 1995; Tu et al, 2004; Warner et al, 2007; Zhang et al, 2010). Numerous studies have found that irrigation substantially increased fruit yield of processing tomato (Tan, 1995; Renquist and Reid, 2001; Hanson et al, 2006; Warner et al, 2007; Patanè and Cosentino, 2010).…”

Water and nutrient management are essential to achieve high yield and desirable quality attributes in processing tomato (Lycopersicon esculentum Mill.). A 4-yr fi eld study (2006)(2007)(2008)(2009) was conducted to assess eff ects of contrasting water management (dripirrigation vs. nonirrigation), fertilizer P (0, 30, 60, and 90 kg P ha -1 ), and K (0, 200, 400, and 600 kg K ha -1 ) on yields and quality of processing tomato when the optimum N rate of 270 kg N ha -1 was applied. Compared with nonirrigation, drip irrigation increased marketable fruit yield by 127%, total fruit yield by 66%, and fruit size by 32%, while it decreased soluble solids content (SSC) by 19% and lycopene content by 8%, with no eff ects on dry biomass of stems and leaves (DBSL). Phosphorus addition had no eff ects on marketable yield and SSC, but increased the DBSL and lycopene content to maximum values at 60 kg P ha -1 . Fertilize K rate aff ected all examined variables but the lycopene content. Increasing K rates from 0 to 200 kg K ha -1 increased marketable fruit yield by 10% and total fruit yield by 9%, but fruit size declined by 3%. Increasing K rates from 200 to 600 kg K ha -1 , however, had no eff ects on yield and fruit size. Fertilizer K rate had no eff ects on SSC with nonirrigation, but resulted in a linear increase in SSC with drip-irrigation. Th e results suggested that, with optimum N supply, K application is required to increase fruit yield and quality of drip irrigated processing tomato.
