Abstract

Spodoptera frugiperda (Lepidoptera: Noctuidae) is a pest that boomed in early 2019. The research was conducted descriptively in areas that had never been attacked by S. frugiperda by planting various types of crops such as sweet corn, white corn, hybrid corn, green beans, tomatoes, chilies and sorghum. The results showed that S. frugiperda was very fond of sweet corn, followed by white corn, hybrid corn and sorghum. Green bean, chili and tomato plants were not attacked by S. frugiperda. Pest S. frugiperda began to attack sweet corn plants at 3 weeks after planting with the initial attack in the form of scratches on the leaves and continued to the base / growing point (leaves still curled). Even this pest also attacks the male flowers that have not opened and attacks the sweet corn cobs. S. frugiperda began to attack sweet corn at the age of 20.33 days after planting, on white corn 25.67 days after planting, hybrid corn 25.53 days after planting and sorghum at 28.67 days after planting. In sweet corn, the attack reached the corn cobs, while in white corn and hybrid corn, the attack only showed damage to the leaves, not to the cornflower as well as to sorghum. The percentage of attack on white corn (22.15%) and hybrid corn (18.26%) and on sorghum was only 10.34% less than attack on sweet corn (40.02%).

Abstract

Planting media is a medium (means) for growing plants. The height of the planting medium is one of the factors that can affect the water needs of plants.The amount of plant water requirements obtained will have an impact on the coefficient value of cherry tomato plants. Besides minimizing the need for plant water to the optimum limit, it is also necessary to maximize crop yields so that the optimal Kc value can be obtained. Therefore, a further study is needed to explain the relationship between the height of the planting medium and the coefficient value of the plant, in order to obtain the appropriate Kc value. This study aims to 1) assess the value of the coefficient of planting on several heights of the planting medium, and 2) examine the differences in the value of the coefficient of plants on several heights of the growing media. This study used a descriptive method to determine the relationship between the height of the growing medium and the height of the planting medium 6, 10 and 15 cm to the coefficient value of cherry tomato plants with autopot. The results showed that the Kc value The Kc value at 6 cm media height was 0.05 in the initial phase, 0.05-062 in the dev phase, and 0.62 in the mid phase. at 10 cm media height was 0.05 in the initial phase, the dev phase was 0.05-0.49, and the mid phase was 0.49. while the height of the 15 cm planting medium was 0.05 in the initial phase, the dev phase was 0.05-0.49, and the mid phase was 0.49. These results are influenced by factors including planting media, ETc, and ETo.

Abstract

In the Indonesian economy, the oil palm commodity plays a pretty bright role because it serves as a source of foreign exchange. The need to develop technology in producing superior seeds. In this study discuss about the Influence of Giving Fertilizer and Mikoriza Against the Growth of Palm Oil Plants (Elaeis guineensis jacq.) In Pre-Nursery Nursery. This study aims to determine the effect of manure and mycorrhizal fertilization as well as its interaction on the growth of coconut plants in pre-nursery nurseries. The study was designed by Factorial Randomized Block Design consisting of 2 treatment factors. The first factor of treatment of manure (K) consisting of 4 levels, namely: K0 = 0 kg / polybag, K1 = 0.15 kg / polybag, K2 = 0.30 kg / polybag, and K3 = 0.45 kg/polybag. The second factor of mycorrhizal treatment (M) consisting of 4 levels, namely: M1 = 12.5 g/polybag, M2 = 25.0 g/polybag, M3 = 37.5 g / polybag. The results showed that the treatment of cow manure up to 0.45 kg/polybag can increase the height of seedlings, stem diameter, total leaf area, wet weight of seedlings and dry weight of seedlings, but did not affect the number of oil palm seedlings.Mikoriza treatment up to 37, 5 g / polybags can increase seed height, stem diameter, total leaf area, wet weight of seedlings and dry weight of seedlings, but have no significant effect on the number of oil palm seedlings. The interaction between cow manure and mycorrhiza had no effect on all parameters observed.
