PENGARUH PEMBERIAN PUPUK ORGANIK GRANULTERHADAP PERTUMBUHAN DAN HASIL TANAMAN KAILAN (Brassica oleracea. L ) DI POLYBAG

Abstract

Effect of Organic Fertilizer on Growth and Yield kailan plants (Brassica oleracea.
L) in polybags. This research is expected to be useful for science and technology, and can
be used as a guide for people who want to cultivate crops kailan. This research has been
carried out in the yard area Kertapati Palembang, starting in December 2014 to February
2015. Research using experimental methods randomized block design (RBD) consisting
of 6 treatments and each treatment was replicated 4 times. The treatment under study is
the application of fertilizer granules P1 = 125 g / polybag (5 ton / ha) P2 = 187.5 g /
polybag (7.5 / ha), P3 = 250 g / polybag (10 tons / ha), P4 = 312.5 g / polybag (12.5 / ha),
P5 = 375 g / polybag (15 tons / ha), P6 = 437.5 g / polybag (17.5 tons / ha). The variables
measured were: plant height (cm), stem diameter (cm), plant fresh weight (g) and plant
dry weight (g). Based on the results of the study showed that the giving of granular
fertilizer with a rate of 312.5 g / polybag or equal to 12.5 tons / ha gives a good effect on
plant height, stem diameter, wet weight of plant, plant dry weight and leaf consecutive
30.48 cm; 0.72 cm; 86.79 g; 8,73 g; 6.95 g and 881,82 cm².
