Performance of vegetative and reproductive characters of some maize inbred line (Zea Mays L.) in ultisol soil applied with the coffee skin compost

Abstract

The objective of the research was to obtain the information of the performance of vegetative and reproductive characters of some maize inbred line on marginal land such as ultisol soil with coffee skin compost. The research was conducted on the experimental house of the Faculty of Agriculture, University of North Sumatera, Medan from October 2018 to February 2019. The split plot design by providing coffee skin compost as the main plot (without giving coffee skin compost; 2.5 kg coffee skin compost: 7,5 kg of ultisol soil; 5 kg of coffee skin compost: 5 kg of ultisol soil) and maize inbred line as subplots (G1: inbred line E, G2: inbred line B, G3: inbred line P, G4: inbred line K). The results showed that the interaction of coffee skin compost with inbred line had a very significant effect on the character of harvest age, cob length and cob weight. Strain B shows a better response for vegetative and generative characters.
