“…Several studies have shown the effect of cucumber plant density on yield (Morrison and Ries 1968;Chambliss and Turner 1972;Downes et al 1972;Cantliffe and Phatak 1975;Widders and Price 1989;Van Wann 1993), but only two were concerned with the little-leaf cucumber type (Cook et al 1991;Staub et al 1992). The relationship between plant density and growth or yield was difficult to determine, since it is dependent upon the genotype of the plant (Nienhuis et al 1984) as well as the environment (O'Sullivan 1980;Tan et al 1983). Cantliffe and Phatak (1975) reported cucumber fruit development is slower at high plant populations (250 000 to 850 000 plants ha -1 ) than at lower densities (50 000 to 200 000 plants ha -1 ) and the number of fruits per plant decreased with increasing plant density.…”

Schultheis, J. R., Wehner, T. C. and Walters, S. A. 1998. Optimum planting density and harvest stage for little-leaf and normalleaf cucumbers for once-over harvest. Can. J. Plant Sci. 78: 333-340. Optimum planting density and harvest stage were determined for once-over harvest of little-leaf and normal-leaf cucumbers. Three harvest stages (10, 25, and 50% oversize fruit) and four plant densities (37,000, 75,000, 150,000, and 300,000 plants/ha) were evaluated on little-leaf cucumber (H-19) and normalleaf cucumber (Sumter and Regal). Plant density did not affect skin color, seedcell size, and seed size in the cultivars evaluated. However, lighter skin color, larger seedcell, and larger seed size were detected at the later harvest stages in H-19. Harvest stage did not influence fruit skin color in Regal and Sumter, but seedcell size and seed size increased quadratically with harvest stage. H-19 produced the highest yield (tonne/ha) and dollar value ($/ha) followed by Regal and Sumter. Considering fruit quality and dollar value, the 10% harvest stage at 330 000 plants ha -1 was the optimum stage and density for once-over harvest of H-19 under North Carolina growing conditions. Higher yield occurred at the later harvest stages, but poorer fruit quality (increased seed and seedcell size, and a lighter skin color) was associated with those stages. Fruit quality and dollar value of Regal was best at the 10% harvest stage at approximately 240 000 plants ha -1 , while 200 000 plants ha -1 was best for Sumter.

“…(Table 5). O'Sullivan (1980) reported a significant N × irrigation interaction, with increased N rates required for once-over harvested pickling cucumber under irrigated conditions. The yield increases in response to high rates of N enhanced total income by $19 502 ha -1 .…”

“…However, the only published study on the effect of N applications and sprinkler irrigation on cucumber yields in a humid climate was based on once-over harvested pickling cucumber (O'Sullivan 1980). In Quebec, processing pickling cucumbers are hand-harvested up to eight times in a season to ensure a high-quality product.…”

“…Nitrogen loss by leaching or denitrification is costly and has a negative effect on the environment (Pier and Doerge 1995;Rahn 2000;Choudhari and More 2002). The total nitrogen rates for once-over harvested pickling cucumber range from 60 to 67 kg ha -1 (Cantliffe 1977;O'Sullivan 1980) while 112 to 169 kg ha -1 are recommended for multiple-harvested pickling cucumber (McCollum and Miller 1971;Doss et al 1977;Forbes and White 1982;Anonymous 2003;Suojala-Ahlfors et al 2005), depending on soil type, weather conditions, cultural practices and crop vigour.…”

. 2007. Yield, quality and revenue of pickling cucumbers with irrigation and supplemental N fertilizer under a humid climate. Can. J. Plant Sci. 87: 571-580. A 5-yr field experiment was conducted in southern Quebec to investigate yield, gross revenue and quality of pickling cucumbers (Cucumis sativus L. 'Fancipak') in response to sprinkler irrigation. In addition, supplemental nitrogen treatments (40 kg ha -1 foliar and granular) following application of 80 kg ha -1 N preplant, as well as non-fertilized and over-fertilized controls (80 kg ha -1 N preplant, 40 kg ha -1 N granular and 60 kg ha -1 N slow-release) were compared in a 2-yr trial under irrigated and non-irrigated conditions. During 1997 to 2000, rainfall was close to or above normal and irrigation did not increase marketable yields. In 1999 and 2000, irrigation reduced early marketable yields relative to non-irrigated treatments. In 2000, a relatively cool year with average rainfall, there was a positive yield response to supplemental N in the non-irrigated plots, but not in the irrigated plots. In 2001, a very hot and dry season, irrigation increased early yield by 66%, marketable yield by 160% and gross revenue by 164% compared with non-irrigated treatments. Non-irrigated treatments did not respond to supplemental N, but supplementing the irrigated treatments with 40 kg ha -1 of N increased marketable yields by 22%, generating 18% additional revenues. Applying N in either a foliar or granular form gave similar results. Overall, under a humid climate, irrigation only had a positive impact on gross crop revenue for pickling cucumbers in 1 out of 5 yr. année caractérisée par une saison très chaude et très sèche, l'irrigation a accru le rendement de fruits hâtifs de 66 %, le rendement de fruits commercialisables de 160 % et les recettes brutes de 164 % comparativement aux résultats obtenus sur les parcelles non irriguées. La culture ne réagit pas au supplément de N en l'absence d'irrigation, mais quand elle est irriguée, un apport de 40 kg de N par hectare augmente le rendement de fruits commercialisables de 22 %, ce qui accroît les recettes de 18 %. L'engrais N donne des résultats analogues, qu'il soit sous forme granulaire ou d'application foliaire. Dans l'ensemble, en climat humide, l'irrigation n'agit positivement sur les recettes brutes issues de la culture du concombre à marinade qu'une année sur cinq.
