Abstract
Productivity of corn (Zea Mays L.) at Various Level s of Shading in Coconut Field (Cocos nucifera L.)
Cocnut cultivation in monoculture had problem in field production, proccessing and marketing thet can cause low coconut farmers income. Therefore we need coconut farm diversification by increasing the potential af land among the coconut trees. Area of land that used coconut palm is onlu about 20% so that the remaining land that can be used for orther commodities is 80%. One of the plants can be cultivated among the coconut is corn. Land use among the coconut palm is expected to increase corn production because corn is one of the leading food commodities and the potential in Indonesia. The objective of this study to determine the productivity of corn plants at different levels of shade by coconut palm. The research was conducted at the experimental Garden Kima Atas, Indonesia coconut and Other Palm Research Intitute (ICOPRI), North Sulawesi. This reasearch was conducted from June to November 2007. The result show that an increase in production of plant dry weight in treatment D (corn planted in open areas) ic higher than terament A (corn grown in between coconut palm oil), B (corn grown in between coconut palm 20 years old) and C (corn grown in between coconut palm 50 years old).
