GROWTH RESPONSE AND YIELD OF ONION (Allium ascalonicum L) AGAINST CHICKEN MANURE FERTILIZER AND DIFFERENT OF CROPPING DISTANCE APPLICATION

Abstract

This research was conducted in Dusun Benteng Jaya Village, Sei Balai Subdistrict, Batu Bara District, Province North Sumatera with altitude of place 5 m asl, flat topography and climate type C. The research was conducted in May 2017 to 2017. This research was arranged based on Factorial Randomized Block Design with 2 treatment factors and 3 replications. The first factor is the dosage of chicken manure (A) fertilizer with 4 levels: A0 0 kg / plot, A1 = 0.5 kg / plot, A2 = 1.0 kg / plot and A3 = 1.5 kg / plot. The second factor was treatment of crop distance (J), with 3 levels ie J0 = 20 cm x 20 cm (25 plants per plot), J1 = 20 cm x 25 cm (20 plants per plot), and J3 = 20 cm x 50 cm (10 plants per plot). The results of the treatment of chicken manure have a significant effect on the growth and production of onion, with the best dose at 1.5 kg / plot (A3)
treatment. Different plant distance treatment significantly affected on growth and production of onion, with the best cropping distance 20 cm x 50 cm (J3). The interaction between chicken manure application and different cropping distance treatment on growth and production of onion showed no significant effect on all parameters observed.
