The Effect of Light and Nutrients on the Development of Fruit of Peanut (Arachis hypogaea (L.). Merr.)

Abstract

This study aims to determine the effect of light and nutrients to the fruit development of peanut (Arachis hypogaea). The study was conducted in the greenhouse of Biology Education Departement of Nusantara PGRI Kediri University by a completely randomized design with two factors, namely: nutrients,  consists of six levels (complete nutrient, without K, Ca, P, Mg and without nutrients) and the light consists of two levels (dark and light condition). The nutrients provided is a Hoagland solution (1938). The parameters measured were the length of fruits, that were measured at the harvesting time. Data were analyzed by F test factorial, and if there is a significant, then continued by least significant difference (LSD) test, using the Stats program 6.2  version. The peanut fruit development is inhibited by light but its stimulated by the interaction between the dark and nutrients. The fruit is grown in the dark with a complete nutrient is the longest both fruits and seeds.
