Cucumber crop was evaluated for the influence of seedling age on its production during two consecutive years of 2011 and 2012 on experimental area of National Agricultural Research Center (NARC), Islamabad, Pakistan. Nursery of cucumber was raised in polythene tubes under protected structures (walk-in tunnels). Seedling transplantation of three different ages viz., 30, 45 and 60 days were compared with direct seeding in the open field. Seedling transplantation produced fruits earlier (22 days), increased availability period (41 days) as compared to direct seeded crop. Transplantation of 45 and 60 days old seedlings produced higher fruits yield of cucumber with higher gross return and gross margin. The results revealed that transplantation of 45 to 60 days old seedlings was suitable for achieving fruits earlier and profitable cucumber production technology.SAARC J. Agri., 13(2): 214-221 (2015)

Downy Mildew Disease

Downy mildew (Pseudoperonospora cubensis) is one of the most important disease of cucumber under open field conditions. Hence, the experiment was conducted to study the efficacy of fungicides in management of downy mildew disease of cucumber (Cucumis sativus L.) under open field in Chauradi-7 Dhading during spring season, 2019. Bhaktapur local variety of cucumber was used for the study. The experiment was laid out in single factor randomized complete block design with four replications. Three different bio-fungicides; Trichoderma viride + Trichoderma harzianum, Bacillus subtilis, Verticillium lecanii and one chemical fungicide; Krilaxyl (metalaxyl 8% + mancozeb 64%) were used as treatments. Normal water spray served as control. It was observed that bio-fungicides had insignificant effect in controlling the downy mildew. Pathological observation such as disease incidence percentage, severity percentage and AUDPC in bio-fungicides treated plots were not significantly different from water-sprayed control plots. Similarly, biometric attributes such as number of fruit, length and diameter of fruit, weight of fruit were also non-significant. Krilaxyl resulted significant effect in controlling downy mildew, providing maximum disease reduction (37.48%-50.72%) with lowest disease incidence (1.25-61.25%) and lowest value of AUDPC (138.7). Krilaxyl treated plots had higher number of fruit (6), longer length of fruit (17.15-18.95), higher diameter of fruit (4.16- 4.45 cm) and higher weight of fruit (677 - 759 g). Hence, chemical fungicide Krilaxyl was found better for the management of downy mildew disease in open field cucumber cultivation. Further, researches on bio-fungicides, especially of native strains are required for best result.

Cluster Distance

Twenty two genotypes of cucumber (Cucumis sativus L.) were evaluated using D2 and principal component analysis (PCA). The genotypes were collected from Plant Genetic Resources Centre (PGRC) of Bangladesh Agricultural Research Institute (BARI), Gazipur , Agro-G, & Lal Teer seed company. The study was undertaken at Sher-e-Bangla Agricultural University Farm, Dhaka during March 2010 to October 2010 to select suitable donor parents for improved breeding of cucumber. Principal component analysis (PCA) revealed that the first two axes accounted for 67.39% of the total variation among the fourteen characters studied. As per cluster analysis, the genotypes were grouped into four clusters consisting 5, 3, 8 and 6 genotypes which revealed that there exist considerable diversity among the genotypes. Highest intra-cluster distance was found in cluster ?I and lowest in cluster ?V. Among four clusters, the highest inter-cluster distance was observed between cluster ?I and cluster ? and lowest between cluster I and cluster ?V. Considering all of the characters studied, the Serena, BD-4305, BD-4256, CU937F1 and BD-4309 were selected for future breeding programme.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22036 J. Environ.

A study was conducted at the research field of Horticultural Research Institute, National Research Center (NARC), Islamabad, Pakistan during two consecutive years of 2011 and 2012 to compare the performance of seedlings raised in polythene bags with traditional direct seeding in respect of early harvesting and profitability. Seedlings of three different ages (40, 50 and 60 days old) of vegetable marrow were compared with traditional direct seeded crop. Transplanted seedlings of vegetable marrow produced fruits 36-38 days earlier and availability period of 34-38 days longer than direct seeded crop. Similarly, higher fruit plant-1, fruit weight plant-1 and fruit yield ha-1 were obtained from seedling treatments. Averaged over years, 50-69% increase in yield and 64-100% increase in profit were recorded in seedling treatments than direct seeded crop. Among seedling ages, 60 days old seedlings were the best performer. The overall results of two years study revealed that seedling transplantation was superior to traditional direct seeded practice of growing vegetable marrow and among those 60 days old seedlings was the best in respect of yield components, fruit yield and profit.SAARC J.

Three herbicide experiments were conducted at the Juana Díaz Research Center in 1980. Preemergence applications of chloramben (3-amino-2-5-dichlorobenzoic acid) at the rates of 4.48 or 8.96 kg ai/ha and postemergence application of DCPA (dimethyl tetrachtoroterephthalate) at 11.2 or 22.4 kg at/ ha provided an excellent control of predominant weeds in pumpkin—(Cucurbita moschata (Duchesne) Pair). There were no significant differences (P = .05) in pumpkin yields among herbicide treatments and hand-weeded or nonweeded checks. DCPA at 11.2 and 22.4 kg ai/ha and chloramben at 6.72 kg ai/ha controlled weeds excellently in cucumber (Cucumis sativus L.) and watermelon—(Citrullus lannatus (Thumb.) Matsm. & Nakai)—during the first 7 weeks. The highest yield of cucumber (20,925 kg/ha) was obtained with DCPA at 11.2 kg ai/ha, whereas the hand-weeded check yielded 16,594 kg/ha. The highest yield of watermelon (51,697 kg/ha) was obtained in the hand-weeded check plots, but good yields of watermelons were also obtained with DCPA at 11.2 kg ai/ha, chloramben at 3.36 kg ai/ha, bensulide (0,0-diisopropyl phosphorodithioate s-ester with N-(2-mercaptoethyl) benzenesulfonamide) at 5.6 kg ai/ha and naptalam (N-1-naphthylphthalamic acid) at 6.72 and 13.44 kg ai/ha, respectively.

Three American cucumber (Cucumis sativus L.) hybrids namely Lot Number (EM 285), labeled number 1, Hybrid super Green F1, labeled number 2 and Hybrid Top CAEEN F1, labeled number 3 were studied. Seeds of these hybrids were exposed to four frequencies of electric current (0, 1, 2, 2.5 ) amber(Am.) for 5 minutes and four periods of exposure for ultra-violate rays (UV) at 224 nanometer (nm) for (0,30,60 and 90) second. The treated seeds were sown on 2010 in open field that prepared and fertilized. The effect of electronic current Am and UV on the production of these hybrids was studied. Flowers number/ plant were recorded after 35 days of sowing; length, radius and weight of fruit were recorded after 46 days of sowing. Results showed significant differences between the hybrids in the studied parameters. Hybrid 3 showed a significant increase compared with hybrids 1 and 2 since it gave the highest number of flowers (19.97 flowers. Plant-1), tallest fruit length and radius of fruit (14.09 and 7.93 cm.fruit-1 respectively) and highest fruit weight 46.97 gm.fruit-1. While hybrid 2 gave 16.72 flower.plant-1, 10.35 cm.fruit-1, 5.72.fruit-1 cm (length and radius of fruit respectively ) and 30.2 g.fruit-1.The results also indicated a significant interaction between electric current and UV in all studied parameters. The 2 Am frequency and 60 sec of UV exposure gave highest flowers number (24.09 flower. plant-1) with an increase 85.16% compared with 2.5 Am frequency and 90 sec. of UV exposure. The results also showed a significant interaction between hybrids, electric current and UV. Hybrid 3 treated with 2 Am and 60 sec exposure gave highest fruit weight 86.33gm.fruit-1 with a significant increase for all tri- interactions.

Cucumber (Cucumis sativus Linnaeus, 1753) stands out in the Brazilian agribusiness of vegetables as it can be consumed in salads (in natura or pickled) or even used for the production of cosmetics and drugs. During cucumber cultivation, several insectpests, mainly from the Orders Hemiptera, Thysanoptera, Lepidoptera, can cause significant yield losses. Therefore, this study aimed to evaluate the entomofaunistic diversity of arthropods in cucumber crop using Moericke and Pitfall traps. Cucumber seedlings were commercially obtained and grown up in the experimental area of   the Federal University of Fronteira Sul – Campus Chapecó (SC). Three samplings were carried out between October and December, 2015. The sampled specimens were identified to the taxon of Order and placed in vials containing alcohol solution (70%). A total of 1.651 specimens were identified and classified into 11 different Orders. Pitfall traps sampled a greater number of orders (9) and specimens (1.309), with emphasis to the Order Hymenoptera (928). For the aerial traps (Moericke), 342 specimens, allocated in eight different Orders, were identified, with the Order Diptera as the most abundant one (153 individuals). Moericke and Pitfall traps showed a Shannon-Weaver diversity index of 1.53 and 1.02, respectively.
