Pruning Methods

A crop of European cucumbers (Cucumis sativus L. ’Corona’) was grown under supplementary lighting (HPS) from 12 Mar. 1987 to 31 Jan. 1988. The flowering, as well as fruit development and production of unproductive flowers was studied using four pruning methods, for winter and summer crops. Pruning method 1 resulted in 12–14 fruit on the main stem. Pruning method 2 lengthened production on short secondary suckers and resulted in 18–20 fruit. Pruning method 3 was used to produce 18–20 fruit on the main stem and on a long secondary sucker growing high up on the plant. Pruning method 4 lengthened production on the main stem, which was made to rest on supporting structures. Our results show that the flowering and fruit production rates are closely related. In summer, the flowering and fruit maturation is shortened and the proportion of marketable fruit is increased. The four pruning methods examined allow good control of spontaneous abortions and a high proportion of marketable fruit, which means a high percentage of productive flowers. However, method 2 was more productive with 4.8 and 6.2 fruit wk−1, respectively, for winter and summer crops.Key words: Cucumis sativus, pruning, supplementary lighting, HPS, cucumber (European)

High Nutrient Concentration

Long English cucumber (Cucumis sativus L.) plants were treated with one of three nutrient concentrations in combination with two fruit thinning treatments forming a 3 × 2 factorial greenhouse experiment. High nutrient concentration enhanced fruit color at harvest and prolonged shelf life but reduced marketable fruit per plant. Thinning of one-third of the fruit from the main stem and laterals had a similar effect. Cucumbers harvested from the upper canopy generally had longer shelf life than those from the lower canopy. Shelf life was correlated with fruit color at harvest.

Research on the application of growth regulators (ZPT) with the type of manure on cucumber fruit production (Cucumis sativus L.), carried out in the experimental garden of the Faculty of Agriculture, Tabanan University, Kediri Tabanan Bali, from February 2018 to April 2018. Using a Randomized Group Design (RACK). The treatment tried consisted of two factors, namely the type of manure and the type of growth agent. The dosing factor of the growth regulator consists of 3 types, namely: Ga = ZPT Atonik dose 0.5 ml l-1 water; Gg = ZPT Gibgro dose 100 mg 10 l-1 water; Gd = ZPT Dekamon dose 0.5 ml l-1 water. Type of manure consists of 3 types, namely: K0 = without manure; Ks = cow manure 4.8 kg polybag-1; Ka = chicken manure 4.8 kg polybag-1, each treatment was repeated three times.     The results show that, the interaction between the type of plant growth regulator and the type of manure had a significant effect on the variable total weight of plant fresh fruit-1, and the weight of fresh fruit-1 fruit. The highest total weight of plant-1 fruit was shown by the combination treatment of Atonik ZPT with chicken manure (KaGa) which is 546.67 g or increased by 50.46% compared to the combination of KaGg treatment which is equal to 363.33 g.      The treatment of the type of growth regulating agent has a very significant effect on the variable number of fruit plants-1, plant fruit length-1 and weight of fruit-1 fresh fruit. The treatment of ZPT Atonik gives the highest fruit-1 fresh fruit weight which is equal to 349.63 g of fruit or increased by 23.53% compared to the treatment of ZPT Gibgro which gives the lowest value of 263.81 g. The treatment of the single effect of manure has a significant effect on all observed results variables.

Glasshouse Cucumber

Plants of the cucumber cv. Farbio (all-female) were planted on 13 or 27 December, 10 or 24 January and grown at 3 minimum night temperatures, 12, 16 or 20 deg C from planting until 1 April. Node number/stem increased as the night temperature fell. Internodes were longer with later planting and on plants on inner rather than outer rows; these responses could not be related to light intensity alone. The number of flowers/stem was determined by the number of nodes bearing flowers and the number of flowers/node. More flowers/node occurred towards the top of the plant and late planting increased flowering at all nodes; the night temperature had little effect on numbers but these were highest at 16 deg . Earliness to flower of the first flowers/axil and the intensity of flowering both rose with temperature. Flowering was delayed only slightly by later planting.

Polyethylene Mulch

Composts may improve crop growth in sandy soils. A biosolids-yard trimming compost (C) was incorporated into sandy soil at 134 t·ha–1 (49.7% moisture) before applying polyethylene mulch. Fertilizer (F) was applied at 0%, 50%, and 100% of the grower's rate (71N–39P–44K t·ha–1 broadcast and 283N–278K t·ha–1 banded in bed centers). `Elisa' pepper transplants were planted 20 Jan. 1994. Marketable fruit weights were 20, 31, and 32 t·ha–1 without C and 30, 35, and 32 t·ha–1 with C for 0%, 50%, and 100% F, respectively. Pepper fruit weights increased with increasing F rates and were higher in plots with C than without C. Without removing mulch, `Thunder' cucumbers were seeded on 26 Sept. 1994. Marketable fruit weights were similar at the three F levels, but were 23 and 27 t·ha–1 without and with C, respectively. One application of C significantly increased bell pepper yields and a subsequent cucumber crop.

Glasshouse Cucumber

Cucumber seedlings, cv. Farbio, planted in the greenhouse on 13 or 27 December or 10 or 24 January, were grown at 21-27 deg C day temperature and 12, 16 or 20 deg night temperatures until 1 April. Later planting produced more fruit than early planting. Night temperature had only a slight effect on fruit numbers/stem, but there was an optimum near 16 deg . The rate of fruit production between 12 and 20 deg was similar, but increased slightly with later planting. Production started earlier with higher night temperature and later planting. Fruit growth was not affected markedly by night temperature and fruit weight at harvest increased with season but was not dependent on the treatments. Fruit length was also independent of night temperature or planting date. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Supplementary Lighting

Eight light treatments were compared to determine the distribution and duration of supplementary lighting (HPS) that are best suited for the production of cucumber (Cucumis sativus L.) in winter. Seven groups of plants were exposed to supplementary lighting in two ways: with day length prolonged without interruption or with nights interrupted, producing photoperiods of 14, 16, 18, or 20 h. A control group was exposed only to sunlight. For a given duration of lighting, the type of light distribution affected neither the vegetative growth nor the early yield of the greenhouse cucumber. Plants exposed to long day lengths showed the best rate of growth and the highest yields: 20 h > 18 h > 16 h or 14 h > control.Key words: Cucumber, supplementary lighting (HPS), photoperiod, greenhouse, Cucumis sativus L.
