Response growth and production of maize (Zea mays L.) in the provision of biological fertilizer with different spacing of lowland

Abstract

Response growth and production of maize (Zea mays L.) in the provision of biofertilizer with different
spacing of lowland. This study aims to determine the effect of biological fertilizer with several different plant spacing
on growth and production of maize in lowland. This research has been carried on in the land Campus C Faculty of
agriculture, University of Muhammadiyah Palembang, Hamlet 1 Semambu Island Village, North Indralaya
Subdistrict, Ogan Ilir South Sumatra. This study was implemented from January s / d April 2015 This study used a
randomized design Divided (Split Plot Design) and each treatment was rpeated 3 times. As the main plot treatment
was planting distance, consisting of : (J1): Spacing 100x30 cm, (J2): Spacing 70x30 cm, (J3): Spacing 40x30 cm.
Treatment subplot consisted of various types of fertilizers, comprising: (H0): Inorganic Fertilizers, (H1): Biofertilizers
Bio P, (H2): Azospirilium, (H3): Biofertilizer Bio P + Azospirilium. As well as all units in the given treatments of
chicken manure 4 ton ha-1. The results showed that the treatment plant spacing 100x30 cm give the highest
influence on the growth and production of maize in lowland and tabulation fertilizer Bio P and Azospirilium
combination provides the highest influence on the growth and production of maize in loeland. As well as the
interaction spacing of 100x30 cm and Bio P + Azospirilium combination gives the best effect on the growth and
production of maize.
