TANGGAPAN PERTUNASAN EMPAT VARIETAS LOKAL, SUKUN TERHADAP PEMANGKASAN DAN PEMUPUKAN NPK

Dedi Setiadi, Hamdan Adma Adinugraha

Abstract

The Study was conducted to examine the sprouting response of four local varieties of bread-fruit to pruning and application of NPK fertilizer. Four local varieties of bread-fruit namely from bone, Banten, Sukabumi and Kediri. The experiment lay out was Randomimized Complete Design with 3 treatment factors. The result did not show significant difference among local varieties. However there are significant differences in budding response . For number of buds. Best treatment was fertilization 20 g and pruning at 50 cm. For buds growth, best treatment was NPK of 30-50 g, and best pruning at 20 and for bud diameter the best NPK dosage was 20 g.

Keywords
