“…A yield response from added P was expected because of the natural acidity and high capacity for P fixation of the Podzol soils of the region (Whiteside 1965) and because some of the experimental sites selected were low in P (Table 1). Also, studies with other vegetable crops showed that added P substantially increased yields (Cutcliffe et al 1967(Cutcliffe et al , 1968Cutcliffe and Munro 1976). However, the lack of response to added P reported here is in keeplng with results of studies conducted with peas in the neighboring province of Nova Scotia (Bishop et al 1968).…”

“…Nevertheless, these rates are considerably higher than those recommended by Wallace (1975) for beetroot (i.e., 0 kg N/ha) and spinach (30 kg N/ha) under New Zealand conditions. They are also higher than those reported overseas for other vegetables (e.g., 225 kg N/ha for Brussels sprouts by Cutcliffe et al (1967); 150 kg N/ha for broccoli by Cutcliffe et al (1968); and 224 kg N/ha for cauliflower by Cutcliffe & Munro (1976). Higher top and root yields of spinach and beetroot were obtained with the (NH,),S04 treatment rather than with the (NH4),S04 + N-serve treatment.…”

Pot and field experiments were conducted to evaluate the effects of nitrogenous (N) fertilisers on the yield of spinach and beetroot. The pot trials involved 2 soils (Wakanui silt loam and Kaiapoi sandy loam), 2 varieties of spinach (Spinacea oleracea L.) 1 variety of beetroot (Beta vulgaris L.), and 5 application rates (0, 150, 300, 450, and 600 kg N/ha) of 6 different nitrogenous fertilisers (potassium nitrate, ammonium sulphate, ammonium sulphate + N-serve, poultry manure, urea, and ammonium sulphate + N-serve + potassium nitrate), The nitrification inhibitor, N-serve, was used to retard the microbial conversion of ammonium fertilisers to the nitrate form, In the field experiment, 1 soil (Wakanui silt loam), 1 spinach variety, and 5 application rates each of potassium nitrate and ammonium sulphate + N-serve were used, Most fertilisers gave maximum yields in pot trials when applied at 300-450 kg N/ha, The highest maximum yields were obtained with potassium nitrate fertiliser and the lowest with poultry manure, Field results showed that significantly higher spinach yields were obtained with the ammonium form of fertiliser compared with the nitrate form, with the maximum yield occurring after application of 300 kg N/ha,

“…Kowalenko and Hall (1987) and Moura˜o and Brito (2001) reported that increased nitrogen advanced maturity for broccoli, while Cutcliffe et al (1968) and Cutcliffe (1971) found that increased nitrogen delayed maturity.

“…Optimal yields of broccoli (Brassica oleracea L. italica Plenck) have been reported with nitrogen rates ranging from 112 to 450 kg N ha (1 , depending on the production system and timing of nitrogen application (Cutcliffe et al 1968;Letey et al 1983;Beverly et al 1986;Shattuck and Shelp 1987;Zebarth et al 1995;Sanchez et al 1996; Thompson et al 2002). Currently, the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) recommends a nitrogen application for broccoli totalling 130 kg N ha…”

in response to increasing rates of pre-plant nitrogen. I Yield and quality. Can. J. Plant Sci. 89: 527Á537. Nitrogen management is critical to the production of broccoli (Brassica oleracea L. italica Plenck). Field trials were conducted in 2001 and 2002 to determine the rate of pre-plant nitrogen required to optimize broccoli yield and quality. Seven rates of nitrogen (0, 50, 100, 150, 200, 300, 400 kg N ha (1 ) as ammonium nitrate were broadcast and incorporated before transplanting two broccoli cultivars, Captain and Decathlon. Maturity of the heads was delayed by 5 d at 0 kg N ha(1 compared with the other rates of applied N. Marketable yield was maximized at 243 to 272 kg N ha(1 for yield expressed in t ha (1 and 171 to 187 kg N ha (1 for yield expressed as cases ha (1 . Averaged over cultivar and year the most economical rate of nitrogen (MERN) ranged from 298 to 309 kg ha(1 , 50 kg higher than estimates for the maximum marketable yield derived from quadratic plateau models. The incidence of misshapen heads decreased and floret color improved as nitrogen rate increased, but hollow stem and head rot also increased with high rates of nitrogen. Floret NO 3 ( -N concentration increased and vitamin C concentration decreased at high nitrogen rates. Applying the rates of nitrogen required to maximize yield may have negative economic and environmental consequences. However, restricting nitrogen also jeopardizes both yield and quality. Hence, the optimum amount of pre-plant nitrogen to apply to broccoli that balances yield, quality, economics and environmental concerns remains a complex issue. , les auteurs ont proce´de´a`des essais sur le terrain afin de de´terminer le taux de fertilisation azote´e requis avant la plantation pour optimiser le rendement et la qualite´de cette culture. Pour cela, ils ont e´pandu a`la vole´e puis incorpore´au sol de l'azote sous forme de nitrate d'ammonium a`sept taux (0, 50, 100, 150, 200, 300 et 400 kg de N par hectare), avant le repiquage des cultivars Captain et Decathlon. Comparativement aux autres taux, l'application de 0 kg de N par hectare retarde la maturation des pommes de cinq jours. Le rendement commercialisable atteint un maximum au taux de 243 a`272 kg de N par hectare quand on l'exprime en tonnes par hectare ou a`celui de 171 a`187 kg de N par hectare quand il est exprime´en cageots par hectare. Le taux d'application le plus e´conomique apre`s calcul de la moyenne par cultivar et par anne´e se situe entre 298 et 309 kg de N par hectare, soit 50 kg de plus que ce que les mode`les a`plateau quadratique estiment ne´cessaire pour parvenir au meilleur rendement commercialisable. L'incidence des pommes difformes diminue et la couleur des fleurons s'ame´liore avec la hausse du taux d'application, mais on note e´galement une hausse du nombre de tiges creuses et de pourriture de la pomme quand le taux d'application est e´leve´. La concentration de N-NO 3 ( dans les fleurons augmente tandis que celle de vitamine C diminue avec la hausse du taux d'application. L'application du ...
