Abstract

Pengaruh Jarak Tanam terhadap Penyakit Busuk Batang Bakteri (Bacterial stalk rot) dan Produksi Benih Jagung Hibrida (Zea mays L.) (The Effect of Spacing on Plant for Bacterial Stalk Rot Disease and Production of Corn Seed). Supervisor: Dr. Ir. Rahmat Ali Syaban, M.Si. and Jajang Mulyana, S.P. Vida Nur Azizatuz Zahro’ Seed Production Technique Study Program Agricultural Production Departemen Program Studi Teknik Produksi Benih Jurusan Produksi Pertanian ABSTRACT The remand for corn seed in the market increases every year and to the increasing need for human and animal food, but to meet these needs, farmers have problems when cultivating, including bacterial stalk rot disease. Setting the right spacing is one of the efforts to suppress the growth of bacterial stalk rot disease so as increase the maximum yield of corn seeds. The research was carried out from july to December 2019 at the production research area of PT. CORTEVA AGRISCIENCE which is located in ajung village, ajung district, jember regency. This study used a non factorial randomized design (RAK) with a spacing factor consisting of 3 treatment levels 70 cm x 17 cm (J1), 60 cm x 15 cm (J2), 65 cm x 16 cm (J3). The data will be analyzed using the variation test or the F test and further tested using the 5% honest significant difference (BNJ) test. The results show that plant spacing has a significantly different effect on the observed variable cob length with an average length of 12,89 cm and has a very significant effect on the variable observation of stem diameter, harvest weight and harvest weight/ha with an average of 18,67 mm, 11.48kg and 5,179.52 kg Keywords: corn, Bacterial stalk rot, spacing.
