Peronosclerospora spp. is one of the problems in the cultivation of maize in Indonesia. Damage caused by the fungus Peronosclerospora spp. can reach 90-100% especially in susceptible varieties. Abiotic environmental conditions such as low temperatures and high humidity accompanied by a layer of water on the leaf surface can increase the occurrence of disease. Disease management techniques are still dominated by the application of synthetic fungicides that have several negative impacts, such as killing non-target organisms, increasing pathogen resistance and environmental pollution. However, these impacts can be suppressed through monitoring activities that play a key role in integrated disease management programs. Monitoring activities facilitate the process of epidemiological analysis through a mathematical model approach so that it can be known patterns of development of plant diseases and the rate of infection as a basis in developing disease management strategies. Therefore, it is necessary to conduct research on disease development models ranging from maize varieties in the improvement of maize plants in Mojokerto Regency. The results showed a model that was able to represent the development of downy mildew in Mojokerto was monit. The highest infection rate was on land using P35 variety from other land using NK 6172 variety.

Tomato (Lycopersicum esculentum L.) has a high market demand prospect. Low production of tomato plants can be caused by providing nutrients that are not optimal for plants. The growth and production of tomato plants can be optimized by providing various treatments, including the provision of appropriate and balanced nutrition using liquid organic fertilizer (POC) (NASA) and the right time interval for administration. This study aimed to determine the effect of NASA POC concentration and the time interval of administration on the growth and yield of tomato plants carried out at UPT 3 Agricultural Service, Kebomas District, Gresik Regency, East Java in December 2019 - March 2020. The study used a completely randomized design (CRD). two factors which are repeated three times. The first factor is the concentration of POC (NASA), consisting of four levels, namely without the provision of NASA POC (control) (P0), 1 ml / l water (P1), 2 ml / l water (P2), and 3 ml / l water (P3). The second factor is the interval of time of administration which consists of three levels, namely once a week (V1), once every 2 weeks (V2), and once every 3 weeks (V3). There was a very real interaction in the combination treatment of P3V2 on the height of tomato plants at the age of 40 days after planting (DAP) (68.06), 50 DAP (80.56), 60 DAP (86.06), and the number of leaves at 40 DAP (20.11. ), 50 DAP (26.56), 60 DAP (35.11).
