Abstract

Sweet potato (Ipomoea batatas L.) with orange flesh enriched with β-carotene andvitamin A can help combat vitamin A deficiency and malnutrition, especially forcommunities in developing countries. The purpose of this study is to select local sweetpotatoes from Lampung which contain β-carotene and to determine an appropriate harvestage to obtain high β-carotene content and production. The study was conducted at theLampung State Polytechnic using a randomized block design (RAK) repeated 2 times.The treatments consisted of 30 genotypes of sweet potato germplasm and 2 harvest ages(3 months after planting and 4 months after planting). The 30 genotypes were selectedbased on flesh color (yellow to dark orange), then tested for β-carotene content andproduction at 3 months and 4 months of harvest. The results showed that from 30genotypes, there were 16 genotypes that had yellow to dark orange flesh color. Thecontent of β-carotene, tuber weight per plant, and number of tubers per plant were higherat 4 months harvest than 3 months harvest. The LPG-01 genotype (Local Lampung) at 3months of harvest had a higher β-carotene content than the other genotypes, which was1,902 µg /100g, while at 4 months the β-carotene content was almost equivalent to theBeta-1 genotype, but higher when compared with other genotypes with 40,493 µg /100g.Genotype of LPG 01 had tuber weight (1,191.90 g per plant) and the number of tubers(5.63 bulbs per plant) higher than the other genotypes. Key words: β-carotene, production, sweet potato, harvest age.

Abstract

Data from the Directorate of Serelia Cultivation shows that Indonesia's sorghum production in the last 5 years has only increased slightly from 6,114 tons to 7,695 tons. The increase in domestic sorghum production needs special attention because Indonesia has great potential for sorghum development (Subagio and Aqil, 2013), therefore it is necessary to respond to the growth and production of sorghum (Sorghum Bicolor L. moench) plants to the application of cow dung bokashi fertilizer and weeding time in the Lebak swamp. This study aims to determine the response of growth and yield of sorghum plants. This research has been carried out by Lr. Karang sublime, Talang Putri Village, Plaju District, Palembang. The design used was a randomized block design (RAK) which was arranged in a factorial manner consisting of two factors, namely the weeding time factor (P) and the cow dung bokashi fertilizer dose factor (K). The treatment factor for weeding time consisted of 3 levels, namely P1 (7 DAP), P2 (14 DAP), P3 (21 DAP) and the dose treatment factor for cow dung bokashi fertilizer consisted of 3 levels, namely K1 (bovine bokashi fertilizer 100g per plant). K2 (bovine dung bokashi fertilizer 150g per plant), K3 (cow dung bokashi fertilizer 200g per plant), so there were 9 treatment combinations with 3 replications/group, where each treatment consisted of 27 plants with 4 sample plants. The variables observed in this study consisted of 1) plant height (cm), 2) flowering age (days), 3) fruit weight (g). The results showed that the treatment of weeding time for 14 days after planting and the application of 200g cow dung bokashi fertilizer per plant had a significant effect on all observed variables.

Abstract

Palm oil (Elaies guineensis Jacq.) belongs to the palm group which produces oil and is used as a raw material for the food and cosmetic industries so that palm oil occupies an important position in Indonesia. One of the obstacles faced in increasing the production of oil palm plants is the attack of plant pest organisms. One of them is the presence of pests. One of the important pests on oil palm plants is the leaf-eating caterpillar, namely the fire caterpillar (Setothosea asigna). Setothosea asigna can cause oil palm plants to suffer leaf damage up to 50%. So that it can cause oil palm plants to lose production up to 78% in the first year after the pest attack and 40% in the second year after the attack. The purpose of this study was to determine differences in population and intensity of pest attacks on two oil palm fields with different plant ages. This research was conducted in Gunung Cahya Village, Buay Rawan District, South OKU Regency. Observations were made by survey methods and direct observation methods (Scan sampling) by calculating the number of populations and determining the intensity of pest attacks. Then the oil palm plants were observed as many as 30 plants/land and the data obtained were carried out by t-test. The results showed that the population and intensity of attack of Setothosea asigna in land 1 was lower than in land 2. In land 1, oil palm plantations had produced good fruit, so treatments such as fertilization and land clearing were routinely carried out. While on land 2 oil palms have not been properly cared for because the plants are in their growth period or TBM (Immature plants) and during their growth period, corn is still planted between plants.

Abstract

Rice (Oryza sativa L.) is one of important crops in current era because the crop produce staple food for more than half of world population. Rice cultivation has been facing many obstacles to reach the expected yield. One the causes is the attack of rice pests causing damages on vegetative and generative stages of the crop, and these would lead to yield reduction. The purpose of this research was to determine the method of cultivating rice plants and arthropods and the level of pest attack. This research was carried out in May 2021 with a survey method on five different rice fields in Bumi Agung Village by interviewing farmers to obtain information about farmers' behavior in rice cultivation and observing insect pests in rice plantations. The results obtained from field practice were the discovery of three pests in rice plants, namely Oxya chinensis, Acrida cinerea, dan Atherigona sp. The control carried out by farmers in controlling pest attacks is in the form of jajar legowo, technical culture such as land management, fertilization, weeding and others which are included in integrated pest control (IPM).From the observational data analyzed that the application of integrated pest control (IPM) has proven to have an impact on reducing pest attacks where out of 5 paddy fields that were observed, the 5th land belonging to Mr. Agus was found to have few insect pests and weeds in his rice fields with an average of 0%.

Abstract

One of the essential factors in crop production is the use of quality seeds. The availability of quality seeds affects the quality and yield. Currently, in the field is that soybean seeds sold by seed stores are seeds that have deteriorated and are stored in unfavorable conditions, causing the quality of the seeds to decline. To continue planting, a technique for improving the performance of soybean seeds is required through matrix conditioning and fertilization. This study aimed to determine the effect of matrix conditioning and fertilization treatment on increasing the growth of soybean seeds stored for two months. This study used a two-factor completely randomized design (CRD) with three replications. The first factor was matrix conditioning media (without matrix conditioning, sawdust, and husk charcoal). The second factor was fertilization (without organic fertilizers and inorganic fertilizers), 100% organic fertilizers, 100% inorganic fertilizers, and 100% organic fertilizers + 50% inorganic fertilizers). The data were tested by using 5% BNT. Variables observed were plant height, number of leaves, leaf dry weight, stem dry weight, root dry weight, and number of root nodules. The results showed that there was an interaction effect between matrix conditioning and fertilization media on the observed variables of plant height, leaf dry weight, and single matrix conditioning treatment that affected the observed variables of root dry weight and number of root nodules in improving seed quality and growth. Keywords: soybean, quality, matrixconditioning, fertilization
