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.

Abstract

Avocado is a fruit crop that is commercial and potential to be widely cultivated. Market demand for avocado was increased so production of avocado seed must increase too by grafting. The problem of grafting is often found in the connection between scion and rootstock that showed like elephant foot phenomenon, so it was necessary to study the linkage process between scion and rootstock. This research leads up to an increased percentage of finished graft seedlings that were ready for planting in the field. This method used a factorial experiment consisting of 2 factors. The first factor was the stages of entres (flushing, endodormancy, and ecodormancy), and the second factor was the grafting method (cleft graft, wedge graft, and splice graft). The research design used Complete Randomized Design with 4 replications and ANOVA with BNJ 5% test. The results showed all observations parameters interacted. Stage ecodormancy in splice graft resulted of vascular tissue (xylem and phloem) between scion and rootstock recovered better than other combination treatments by producing the best-grafted avocado seedlings growth with an increased percentage of grafted seedling by 42.50%, an interval of flushing by 4.91 days, and increased frequency of flushing by 1.83 times compared to stage flushing in cleft graft.
