Abstract

The aim of the experiment was to investigate and evaluate planting model of maize and planting time of mustard in intercropping sistem on leaves area, total dry matter and seed yield of maize. The experiment design was at split plot, with 2 planting model (single and doble row) of maize and planting time of mustard (10 days prior to maize planting, along with maize planting, and 10 days after maize planting). The results showed that planting model of maize is not effected by time planting of mustard in intercropping systems. Double row planting of maize showed the leaves area, total dry matter and seed yield of maize were not significantly different from model of single row. Likewise mustard planting time showed no significant differnce among the three planting time on of the leaves area, total dry matter and seed yield of maize. The study indicate that the insertion of mustard plant on maize crops can improve land use. Land equivalent ratio in maize intercropping with mustard at 1.81.Key word : Planting model, planting time, intercropping, maize, mustard

Abstract

The yield potential test is an important step in breeding activity in creating new varieties through evaluation the desired genes on some lines (Basuki, 1995). The value of heritability could indicate that every character observed was genetically influenced which inherited from the parental lines and its interaction with environmental factors. On this basis, this research was conducted at the Sawaulan, Tawang Agro Village, District Karangploso, Malang, East Java. The used materials in this research were three lines of yellow pod common beans of F6generation (CS x GK 50-0-24; CS x GI 63-0-24; and CS x GI 63-33-31), three parental varieties and Lebat-3 variety as check varieties. The completely randomized block design was used by observed 10 samples of plants per plot. This research showed that the three lines of common bean tested had uniformity in all characters evaluated by using quantitative and qualitative analysis. The value of GCV (Genotypic Coefficient of Variance) in every characters evaluated of the tested lines were low criteria and these values were lower than in the check varieties. The low variation indicated the small variation, i.e that the lines were already uniform. The heritability value of some characters observed in the lines were lower, while some other characters still had high heritability value. The heritability in the three lines tested were influenced by environment and genes as well. The character that had high heritability could inherit uniformly the character in concern on the next generation. The high heritability shows that the plant breeding program especially the selection program has been succesful.
