- The addition of soil volume and the number of seeds can increase the growth and yield of corn plants. This research was conducted on Eka Warni Medan Johor, North Sumatra, Medan, Indonesia. This research was conducted from July 2018 until November 2018. This research aimed to obtain the right soil volume and number of seeds per planting hole in an effort to increase the production of corn (Zea mays L.). This research used a completely randomized design and was tested further with the Duncan's Multiple Range Test. The treatments in this research were soil volume, namely: V1 = 75 cm x 15 cm (22.5 dm3) V2 = 75 cm x 25 cm (37.5 dm3), V3 = 75 cm x 30 cm (45.0 dm3), V4 = 75 cm x 40 cm (60.0 dm3), all of planting space were multipled by 0,20 meters, which is the depth of soil, amount of seed treatments were B1 = 1 seed per polybag, B2 = 2 seeds per polybag, B3 = 3 seeds per polybag, variety used was Bisi-18. Variables in this research were plant height, number of leaves, stem diameter, wet weight and dry weight of stover, wet weight and dry weight of roots, wet weight and dry weight of cob, wet weight and dry weight of husk, wet weight and dry weight of seeds, wet weight and dry weight of seedless cob. The results showed that the volume of soil significantly affected the stem diameter. The number of seeds in polybag significantly affected the number of leaves, stem diameter, wet weight and dry weight of stover, wet weight of root, wet weight and dry weight of cob, wet weight and dry weight of seeds, wet weight and dry weight of husk, wet weight and dry weight of seedless cob. Interaction of soil volume and number of seeds in polybag had an effect on 7 weeks after planting, stem diameter 2-5 weeks after planting, wet weight and dry weight of cob, wet weight and dry weight of seedless cob, wet weight and dry weight of husk, wet and dry weight of seeds so the best result was the treatment with soil volume of 22.5 dm3 and 3 seeds per planting hole, the yield was 37.52 tons / ha.
- Penambahan volume tanah dan jumlah benih mampu meningkatkan pertumbuhan dan hasil produksi tanaman jagung. Penelitian ini dilaksanakan di Jalan Eka Warni Medan Johor, Sumatera Utara, Medan, Indonesia, dilaksanakan pada bulan Juli 2018 hingga November 2018. Penelitian ini bertujuan untuk memperoleh volume tanah dan jumlah benih per lubang tanam yang tepat dalam upaya meningkatkan produksi tanaman jagung (Zea mays L.). Penelitian ini menggunakan rancangan acak lengkap dan diuji lanjut dengan Uji Jarak Duncan (Duncan’s Multiple Range Test). Perlakuan yang digunakan adalah volume tanah yaitu: V1 = 75 cm x 15 cm (22,5 dm3),V2 = 75 cm x 25 cm (37,5 dm3), V3 = 75 cm x 30 cm (45,0 dm3), V4 = 75 cm x 40 cm (60,0 dm3), semua jarak tanam dikali dengan 0,20 meter yaitu kedalaman tanah, perlakuan jumlah benih yaitu: B1 = 1 benih per polybag, B2 = 2 benih per polybag, B3 = 3 benih per polybag, varietas yang digunakan Bisi-18. Peubah amatan yaitu tinggi tanaman, jumlah daun, diameter batang, bobot basah dan kering brangkasan, bobot basah dan kering akar, bobot basah dan kering tongkol, bobot basah dan kering klobot, bobot basah dan kering biji, bobot basah dan kering tongkol tanpa biji. Hasil penelitian menunjukkan bahwa volume tanah berpengaruh nyata terhadap diameter batang. Jumlah benih per polybag berpengaruh nyata terhadap jumlah daun, diameter batang, bobot basah dan kering brangkasan, bobot basah akar, bobot basah dan kering tongkol, bobot basah dan kering biji, bobot basah dan kering klobot, bobot basah dan kering tongkol tanpa biji. Interaksi volume tanah dan jumlah benih mampu meningkatkan jumlah daun (7 MST), diameter batang (2-5 MST), bobot basah dan kering tongkol, bobot basah dan kering tongkol tanpa biji, bobot basah dan kering klobot, bobot basah dan kering biji sehingga diperoleh hasil yang paling baik yaitu dengan volume tanah 22,5 dm3 dan 3 benih per lubang tanam didapat hasil 37,52 ton/ha.
