APPEARANCE OF SEVERAL MAIZE PLANTS (Zea mays L.) IN DIFFERENT GROWING ENVIRONMENTS APPEARANCE OF SEVERAL MAIZE PLANTS (Zea mays L.) IN DIFFERENT GROWING ENVIRONMENTS

Abstract

This research is aimed to study the growth and yield of several maize (Zea mays L.) in different growing environments. This research was conducted in May to September 2019, located in the village of Labuan Haji, District of Labuan Haji, East Lombok Regency, West Nusa Tenggara. The method that is used in this research is experimental research by experimenting in field. The design used is the Split Plot Design which consists of two factors. Growing Environmental Factors (T) as the main plot consists of 3 levels, namely: organic fertilizer 15 tons.ha^-1 + Urea fertilizer 200 kg.ha^-1 + spacing 70cm x 20cm (t₁), organic fertilizer 15 tons.ha^-1 + Urea fertilizer 200 kg.ha^-1+ Phonska fertilizer 250 kg.ha^-1 + spacing (40cm x 30cm) x 60cm (t₂), and organic fertilizer 20 tons.ha^-1 + Urea fertilizer 200 kg.ha^-1 + Phonska fertilizer 250 kg.ha^-1 + spacing (50cm x 20cm) x 100cm (t₃). Genotype factor (V) as a subplot consisting of 4 levels, namely: population C2 (v₁), Lamuru variety (v₂), Arjuna variety (v₃), and Sukmaraga variety (v₄).  Each experiment was repeated 3 times to obtain 36 units of the experiment. The results showed that the genotype treatment significantly affected the growth and yield of maize plants except plant height. The treatment of growing environment has no effect on the growth and yield of the four genotypes of maize planted except the age of male flowers and the diameter of the cob. The interaction between the growing environment and genotypes also significantly affected the yield, with the highest yield owned by the Sukmaraga variety in the growing environment 2, which was 5.80 tons.ha^-1.
