Authors:Waskitha Budi Pramana, Hartini Hartini Pages: 93 - 101 Abstract: This study aims to determine the dose and time of application of the best coffee dregs Liquid Organic Fertilizer (POC) for sugarcane seedlings (Saccharum officinarum L.) cening variety bud set. The sugarcane seeds used are obtained from PG. Lestari, Patianrowo, Nganjuk, East Java. The study was compiled using a randomized block design (RBD) with 2 treatment factors. The first factor is the POC dosage of coffee dregss with treatment variations P0 without fertilizer application, P1 with a dose of 10ml / liter of water, P2 30ml / liter of water, and P3 50ml / liter of water. The second factor is application time with 3 variations of treatment, namely M1 POC applied to sugarcane 1-3-5 weeks after planting (MST), M2 at sugarcane age 2-4-6 MST, and M3 at sugarcane 3-5-7 MST age. Data analysis used variance (ANOVA) with a significant 5%, if there is a significant difference, continue with the Duncan Multiple Range Test (DMRT). The results showed that the interaction between dose treatment and application time of coffee dregs POC had no significant effect on plant height, number of leaves, stem diameter, root length, wet weight and dry weight. Different dosage treatments had a significant effect on plant height, number of leaves, root length, wet weight and dry weight. Different application time treatments had a significant effect on plant height, wet weight and dry weight. The best dosage for coffee dregs POC for sugarcane is 30 ml / liter of water. The best application time for coffee dregs POC is at the age of 3-5-7 MST sugarcane. PubDate: 2021-06-30 DOI: 10.31289/agr.v5i2.5031 Issue No:Vol. 5, No. 2 (2021)

Authors:Azwana Azwana Pages: 112 - 121 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%).

Authors:Nurpilihan Bafdal Pages: 164 - 171 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. PubDate: 2021-06-30 DOI: 10.31289/agr.v5i2.5456 Issue No:Vol. 5, No. 2 (2021)
