Pertumbuhan dan Hasil Tanaman Mentimun (Cucumis Sativus L.) Akibat Perbedaan Jarak Tanam dan Jumlah Benih Per Lubang Tanam

. The study was aimed at determining the right spacing and seed numbers per hole on growth and yield of cucumber plants and investigating interactions between the two factors. The study was conducted at the Experiment Station of Agriculture Faculty of Syiah Kuala University, Darussalam, Banda Aceh from October to December 2009. Experiment was arranged in a factorial randomized complete block design (RCBD) 3 x 3 with three replications. Factors studied were plant spacing (20 cm x 60 cm, 30 cm x60 cm, and 40 cm x 60 cm) and seed numbers per hole (1, 2, and 3 seeds per hole). Results showed that plant spacing exerted a highly significant effect on fruit weight per plant and a significant effect on fruit length. The best fruit weight and length were obtained at a spacing of 40 cm x 60 cm. Seed numbers exerted highly significant effects on fruit diameter and fruit weight per plant and significant effects on main stem length at age 15 days after planting and fruit numbers per plant. The best fruit diameter and fruit weight per plant were found at 1 seed per hole, while the best fruit numbers per plant was obtained at 3 seeds per hole. There was no significant interaction between plant spacing and seed numbers per hole on growth and yield of cucumber
