Abstract

The nitrogen reduction in soil is a problem in maize cultivation that can cause production decrease. The efforts to prevent this problem is to assemble superior maize that is low nitrogren resistance and high production by crossing different corn former plants. This research was to analyze the combining power of five strains (G1, G2, G3, G4 and G5) under normal and low nitrogen conditions used a half diallel cross design by Griffing I method formula to analyze 10 genotypes. The research design used a divided plot design (RPT) with 3 replications, the research location was in the experimental garden of Balai Pengkajian dan Teknologi Pertanian in Kebondalem village, Mojosari district, Mojokerto district and the application of nitrogen fertilizer. The value of the general combining ability (DGU) of the G3 elders significantly affected the weight parameters of the cobs under low nitrogen conditions. The results of the special combining ability (DGK) on the G7 and G8 crosses had high DGK values on harvest character and weight of 100 seeds under normal and low nitrogen conditions. The genotype G6 has a high DGK value for cob weight characters.

Abstract

Maize is a leading commodity in the agricultural industry. Efforts to increase maize seed production and quality are very important, considering the important role of maize commodities in the global and local food systems. This study aims to evaluate the production results of 20 single-cross maize hybrid combinations through the analysis of agronomic traits and productivity results. The experiment was conducted using a randomized block design with three replications in 60  plots. The agronomic characters observed included cob length, cob diameter, number of seed rows per cob, and seed weight per cob. The Genotype R hybrid combination stands out as a superior variety with the highest productivity, supported by strong agronomic characteristics. Meanwhile, the Genotype T hybrid shows the lowest performance, highlighting the importance of developing varieties suited to specific environmental conditions. This research makes a significant contribution to agricultural innovation in Indonesia, especially in improving food security and productivity of the agricultural sector.

Abstract

Reduction of nitrogen in the soil is a problem in corn cultivation that can cause decrease production. The efforts to prevent this problem is to assemble superior maize that is low nitrogen resistance and high production by crossing different corn elders. This study was to analyse the combining ability of five lines (G1, G2, G3, G4 and G5) under normal and low nitrogen conditions used a half diallel cross design using the Griffing’s model I method formula to analyse 10 genotypes. The research design used a split plot design (SPD) with 3 replications, the research location was in the experimental garden of Center for Agricultural Research and Technology in Kebondalem, Mojosari, Mojokerto East Java. The value of the general combining ability (GCA) of the G3 elders significantly affected the weight parameters of the cobs under low nitrogen conditions. The results of the specific combining ability (DGK) on the G7 and G8 crosses had high SCA values on the yield character and weight of 100 seeds under normal conditions and nitrogen stress. Genotype G6 has a high SCA value for cob weight characters.
