Penelitian ini berjudul Efektivitas pemberian pupuk organik terhadap pertumbuhan anakan pisang yang diperbanyak melalui pematian titik tumbuh. Penelitian ini bertujuan untuk mengetahui efektivitas pemberian pupuk organik terhadap pertumbuhan anakan pisang. Penelitian dilakukan pada bulan 25 Desember-20 Februari dikebun percobaan Fakultas Pertanian Universitas Medan Area. Penelitian ini menggunakan rancangan acak lengkap non factorial dengan lima ulangan dan 5 perlakuan dimana M0(0 ton/Ha), M1 (3.12 kg pupuk organik/tanaman atau setara dengan 5 ton/hektar), M2 (6.25 kg pupuk organik/tanaman atau setara dengan 10 ton/hektar), M3 (9.37 kg pupuk organik/tanaman atau setara dengan 15 ton/hektar), M4 (12.5 kg pupuk organik/tanaman atau setara dengan 20 ton/hektar). Hasil penelitian menunjukkan bahwa pemberian pupuk organik dapat meningkatkan bobot basah dan jumlah daun pada anakan pisang. Peningkatan berat basah anakan ini disebabkan unsur hara yang diserap oleh akar akan dimanfaatkan untuk mendorong diferensiasi sel pada batang pisang. Dari hasil pengamatan terlihat bahwa semakin tinggi dosis pupuk organik yang diberikan maka jumlah daun pada anakan tanaman pisang semakin banyak. Hal ini tidak luput dari peran akar yang tumbuh dan berkembang dengan baik.
The increase of rubber production can be done by introducing tapping technology for rubber farmers, when rubber prices are low. The facts showed that smallholder rubber production is still low, in the range of 600-800 kg of dry rubber / ha / year. Tapping practiced by rubber farmers is generally not based on tapping technology, which is integrated in the aspects of plants, tapping planning and management, the use of stimulants, and a number of other technical aspects. To increase smallholder rubber production, rubber tapping technology was introduced to Mekar Tani Groups in Sari Laba Jahe Village, Sibiru Biru Sub-district, Deli Serdang District (North Sumatra). The results of the introduction in the form of stimulant application showed that a month after applying the stimulant, the increase in production averaged 60.65%. If production without applying the stimulant was 0.18 kg / tree, then after applying the stimulant 0.28 kg / tree was obtain. The results of this study within a month were still continuing to observe other aspects such as the quality of rubber produced due to the application of stimulants, as well as farmers' income.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
