Abstract

Increased productivity of maize can be done with the use of high quality seeds from improved varieties such as hybrid seed. The objectives of this study were Increasing productivity of maize female parent is important in order to reduce the price of hybrid seed. The objectives of this study were to determine the nitrogen fixing bacteria compatible with phosphate solubilizing bacteria (PSB), and using those bacteria to increase physiological seed quality and seedling growth of maize female parent. The research consisted of laboratory and field experiments. Laboratory experiment for the isolation and identification of rhizobacteria resulted in 25 Azotobacter and 29 Actinomycetes non-pathogenic isolates capable of fixing nitrogen and PSB selected for compatibility tests were AB3, B28, P12, P14, P24, and P31. The compatibility test showed 25 pairs of BPF with Azotobacter and 16 pairs of BPF with Actinomycetes were mutually compatible. The BPF pair with Azotobacter or Actinomycetes P24-AzL7, P24-AzL9, B28-AcCKB4, P24-AcCKB9, P24-AcCKB20, and P24-AcCKW5 were able to increase the vigor index of hybrid maize female parent seed. Field experiment was arranged in a split plot design with three replications. The main plot was dosage of N-P fertilizer (0%, 25%, 50%, 75%, and 100% of recommendation dosage), and the subplot was 12 rhizobacteria treatments selected from 25 compatible pairs of BPF with Azotobacter and 16 pairs of BPF with Actinomycetes and 1 control. The application of compatible pairs of bacteria had a significant effect on plant height, the number of leaves at 3 and 4 weeks after planting and plant dry weight. However, the best treatment i.e. B28-AcCKB4 was not significantly different with the nutrient broth treatment (as control).

Abstract

Paria is a plant that is usually cultivated to be used as a vegetable or medicinal ingredient. This research was conducted to determine the effect of physical and chemical treatment on the health quality and viability of Bitter Gourd Seeds. This research was conducted from February to June 2022 at the CV Jogja Horti Lestari Laboratory and the Bantul Pest and Diseases Laboratory. The study was conducted using a single factor Completely Randomized Design (RAL) analysis, which consisted of 9 levels and 3 replications, if the treatment showed a significant effect on the observation results, further testing was carried out using the Honest Significant Difference Test (Tukey) at the 5% level. The results showed that physical and chemical treatment had an effect on the health quality of seeds, namely physical treatment with hot water soaking at 53oC for 10 minutes had a significant effect on suppressing the growth of seed-borne pathogens with a growth rate of only 0,75%, but the effect of physical and chemical treatment in viability had no significant effect on germination, growth synchronously, maximum growth potential, and growth speed.
