EFFECT OF PRUNING AND POP SUPERNASA FERTILIZER APPLICATION ON GROWTH AND YIELD OF MELON (Cucumis melo L)

Abstract

This research was conducted in Sirsak Street, Kisaran Timur Village, Asahan District, North Sumatra. Flat Topography, height  25 m asl, and coordinate point 203'-326' North Latitude and 991'-1000' East Longitude. The experiment was conducted in May ― July 2017. This research is based on the Randomized Block Design (RBD) factorial with 2 factors and 3 replications. The first factors was the pruning of 3 levels P0 = Control (no pruning), P1 = pruning
and leaving 6 branch ( 7, 8, 9, 10, 11, and 12), P2 = pruning and leaving 4 branch ( 7, 8, 9 and 10). The second factors is application of POP Supernasa fertilizer with 4 levels S0 = Control ( 0 ml/l water/block), S1 = 20 ml/ 10 L water/block, S2 = 40 ml/ 10 L water/block, S3 = 60 ml/ 10 L water/block. The result of research that pruning P2 = pruning and leaving 4 branch ( 7, 8, 9 and
10), the best production contained is the parameter diameters of fruits 18,01 cm and production/plant 4,11 kg. Applications of POP Supernas S3 = 60 ml/ 10 L air/plot, the best production contained is the parameter flower emergence 19,33 day, fruit emergence 23,33 day, fruit diameters 17,97 cm and productions 4,10 kg/ plant. The interactions pruning and POP Supernasa application on growth and yield of melon showed no significant effect on all parameters was observed.
