Waktu tanama dan populasi tanaman jahe (Zingiber offinale Rosc.) sebagai tanaman kedua dalam pola tanam beruntun

Abstract

This study was designed to Jind out some cultural practices, i.e. the planting time and plant population, to minimize the yield losses of the second crop in ginger continuous cropping pattern. The pot experimental unit consist ofplanting time treatment (A) with 3 levels i.e. 1, 2, and 3 monts after the harvesting of the first crop, and popuration treatment (B) with 3 levels i.e. 1, 3, and 5 plants/pot. The result shows that the growth and yield were not aflected by the planting time treatment, but afected by the plant population treatment. By increasing the plant population fiom I plant/pot (equivalent to 33 300plantsha.) up to 3plants/pot (equivalent to 99 900plants/ha.), the yield reduced about 2 7.56% in term of tuber fiesh weight, but did not aged the tuber growth. Increasing the plants/ha is not recommended since the production was appraised in term of tuber fiesh weight.
