Endophytic fungi are fungi that live in healthy plant tissues without causing disease symptoms. Endophytic fungi in chili have been tested as both biocontrol agents and growth promoters, but their colonization has not been reported. Therefore, this study aimed to determine the level of colonization of endophytic fungi and its effect on the growth of chili seedlings. A total of 8 endophytic fungi were prepared at a density of 2.8 × 106 CFU mL-1. Then the endophytic fungus was inoculated 2 times, first by soaking the seeds, and secondly by watering the endophytic fungus suspension on chili seedlings aged 3 weeks after sowing. Endophytic fungi were re-isolated on chili seedlings that were 4 weeks old after sowing on the roots and stems to determine their colonization ability. Chili seeds were then maintained for up to 4 weeks after transplanting to observe their growth. The results showed that the endophytic fungal colonization ranged from 26-60% on the chili root, while at the base of the stem it was 20-40% with a different pattern of colonization distribution. In addition, endophytic fungus colonization was also able to increase the shoot height and root length of chili seedlings.

The implementation of intercropping is one alternative that can be done to increase the diversity of crops cultivated by farmers, due to the increasing activity of land conversion and limited ownership. The practices of growing several types of crops on the same land and time can provide several advantages. The plantation of corn and shallot on the same field and at the relatively same time will contribute to meet the community's needs for food and feed, especially during the current covid-19 pandemic. The use of various spacing of shallot within corn plantations is expected to increase income and land-use efficiency. The results showed that narrow space of shallots (10 cm × 15 cm) gave a higher unit area yield, and a wider space (20 cm × 20 cm) gave a higher land equivalence ratio comparing to other plant spacing (10cm × 15cm, and 10cm × 20cm).

One of the pests that attack corn plants in Banyumas is the armyworm pest (Spodoptera frugiperda) which has been endemic since early 2019. This pest can cause damage to up to 70% of the total land area of the corn crop. Generally, pest control is carried out using chemical pesticides which have a negative impact on the environment and health. Therefore, to overcome these negative impacts it is necessary to do better control such as control using vegetable pesticides or biopesticides. One of the plants that can be used as vegetable pesticides is the gadung tuber which contains diosgenin, steroid, saponin, alcohol, and phenol compounds. This study aims to determine the difference in the effectiveness of the vegetable pesticides of the gadung tubers which were extracted using two different methods, namely by blending and boiling. The resulting vegetable pesticides were applied to 25 samples of the pest Spodoptera frugiperda. The method of analysis used a qualitative descriptive method. The results showed that after the application of vegetable pesticides twice the samples of the caterpillars used were dead, which was indicated by the visual death appearance of Spodoptera frugiperda where the body turned stiff and secreted fluid, the color of the body turned blackish brown (burnt). The difference in the effectiveness of the results of the application of vegetable pesticides was seen in the mortality rate of caterpillars where for the caterpillars that were applied with boiling of 25 samples, 12 caterpillars that died on the second day, the third day 5, the fourth day 4 caterpillars and the fifth day 4 caterpillars. Meanwhile, for the death rate of caterpillars that were applied with blending of 25 samples, the caterpillars that died on the second day were 10, the third day 7, the fourth day 6, and the fifth day as many as 2 caterpillars. The application of both gadung tuber vegetable pesticides made by blending and boiling is considered equally effective in controlling armyworm pests but seen from the faster mortality rate using vegetable pesticides made by blending.

PGPR (Plant Growth Promoting Rhizobacteria) is a substance that helps plant growth with the help of rhizosphere microorganisms. PGPR propagation can be done with liquid media. This PGPR propagation needs to be done because this substance has many benefits for agricultural cultivation. The application of PGPR to the test plant, namely the pakcoy plant, proved that there was an effect of giving PGPR to the plant. Observations on the test plants were carried out by observing several observation variables such as plant height, root length, number of leaves, wet weight and dry weight. The results of these observations showed that the effect on the test plants was seen in the variables of root length, wet weight, and dry weight. Meanwhile, the variable plant height and number of leaves did not show a visible difference.
