Identifikasi dan Efektivitas Berbagai Teknik Pengendalian Hama Baru Ulat Grayak Spodoptera frugiperda J. E. Smith pada Tanaman Jagung berbasis PHT- Biointensif

The presence of new pest Spodoptera frugperda J. E. Smith has the potential to reduce corn production, so its existence needs to be controlled. The aim of this research is to obtain control techniques that could reduce the intensity of S. frugiperda pest’s attack. The research was conducted from June to October 2020. The experiment was designed in a randomized block design (RBD) with 9 replications and 3 treatments consisting of non-control (NP), PHT-biointensive (BI), and synthetic pesticides. In BI treatment, neem leaf extract (25 mL/plot) and Beauveria bassiana (6,25 g/plot) were used. Meanwhile, the PS treatment used deltametrin active ingredient (3,125 mL/plot). The volume of spray used was 1,25 L. The results showed that PS control techniques gave the best results in suppressing the intensity of fall armyworm S. frugiperda attacks (0,57%-7,04%) followed by BI treatment (0%-6,89%) and NP (0,97%-8,29%). The highest pest populations overall were found in NP treatment and the lowest in PS treatment. PS treatment provided the highest production result with a cob weight of 18,6 kg/plot (24,81 tons/ha), while BI treatment of 17,00 kg/plot (22,72 tons/ha) and NP of 15,44 kg/plot (20,64 tons/ha). The results of the correlation test between the intensity of pest attacks and production results showed that the higher the pest attack, the lower the harvest weight produced. Therefore, pest control by using synthetic pesticides made from active deltametrin is declared effective in suppressing the intensity of attacks and populations of fall armyworm S. frugiperda and able to provide high production results.

The Fall armyworm worm (FAW) (Spodopterafrugiperda) is one of the important economic pests which goes on several field crops and causes serious damage. The aim of this study was to look for efficient, less cost and environmentally friend plant extract for controlling Fall armyworm worm in cereal crops. A Complete Randomized Block Design (CRBD) experiments with three replications were conducted in the laboratory to investigate the insecticidal effects of four plant extracts consisting of ethanolic extract of Neem (Azadirachta indica) seeds, Black pepper (Piper nigrum) seeds, Usher (Calotropis procera ) leaves and water extracts of Argel (Solenostemma argel) leaves on larvae of the Fall armyworm (FAW) (Spodoptera frugiperda). Newly emerged larvae of FAW were treated topically by 4 concentrations (10, 25, 50 and 75%) of each extract, and then the larval mortalities were calculated after 24, 48 and72 hrs. The results showed the highest concentrations (75%) of the three ethanolic extracts gave higher mortality percentages (100%) after 72 hrs of exposure, compared with other concentrations. Also, these were not significantly different from the recommended dose of the standard pesticide “Spinosad”. On the other hand, Argel water extract showed no effect on the (FAW) larvae. It is recommended that this experiment to be replicated under different environments.

The great economic importance attributed to strawberry cultivation raises the interest in cultivars of high productivity and superior fruit quality. The quality of fruit is the most impacting factor for the strawberry marketing, but selecting genotypes that combine high production and high fruit quality has been a difficult task. The objective of this study was to determine the linear relationships between phenological, quality and production variables of strawberry aiming at identifying potential variables for indirect selection in future selection processes of strawberry genotypes. A trial was conducted in a randomized block design with two cultivars and two transplant origins, grown in four types of substrate. Fifteen variables, including phenological, productive and fruit quality-related variables were assessed. The selected variables explained 45.2 and 39.1 % for PC1 and PC2 respectively, totaling 84.3 % of the total variance of the variables in the PCA, and indicated important relationships between the variables, and a path analysis revealed success for indirect selection of total mass of fruits based on the total number of fruits (0.81413). Changes in crop management that reduces the period between planting date and full flowering may be an alternative to increase the production of strawberry and provide fruits with higher quality.

One of these pest control techniques is by controlling technical culture of polyculture planting system. This research was conducted in July to October 2019 which was located in Banyuputih Village, Wringin District, Bondowoso Regency. This study used a Randomized Block Design (RBD) with six treatment, namely: P1 = polyculture of shallot + Lemongrass; P2 = polyculture of shallot + celery; P3 = Polyculture of shallot + mustard; P4 = Polyculture of shallot + Lemongrass + mustard; P5 = Polyculture of shallot + celery + mustard; P6 = Monoculture of shallot. Each treatment was repeated 4 times. Observation started at 30 days after planting. Data collection was done by observing directly on the sample plants. Sampling was carried out using Yellow trap and pit fall trap. Samples were taken at each plot 10 times with intervals of 4 days. Observations included collecting the pest insects and natural enemies that were found, counting the number of populations in each species, scoring towards the damage plants. The results showed that shallot planting by polyculture with different types of plants affected the population of pests and natural enemies as well as the level of diversity of insects in shallots. Planting shallots by polyculture has been proven to control pest populations compared to planting shallots by monoculture. Polyculture planting with two types of plants proved to be better than polyculture planting with three types of plants where the best treatment was found in P1, namely polyculture of shallot and lemongrass with the smallest pest population which was 17.5.

The Difference

This study aimed to examine Organonitrofos Plus fertilizer (OP) on sweet corn (Zea mays Saccharata L.) and its effect on changes in soil chemical properties of Ultisols. Organonitrofos Plus fertilizer is an enhancement of Organonitrofos fertilizer enriched with microbes at the beginning of the manufacturing process. Research was conducted in the greenhouse of Integrated Agricultural Laboratory of Lampung University. Treatment applied was a factorial of 4 × 2 × 3 with three replications in a randomized block design. The first factor was the dose of OP fertilizer (0, 10, 20, 30 Mg ha-1), the second factor was the dose of inorganic fertilizers (without inorganic fertilizers, and with inorganic fertilizers, namely Urea 0.44, 0.28 SP-36 and KCl 0.16 Mg ha-1), and the third factor was the dose of biochar (0, 10, 20 Mg ha-1). By a single OP fertilizers, inorganic fertilizers, and the interaction between the OP and the inorganic fertilizers increased the weight of dry stover, cob length, cob diameter, cob with husk and cob without husk of corn. OP fertilizers which are applied in Ultisols can improve soil fertility and increase corn production so that OP fertilizer can lessen the use of inorganic fertilizer and can be used as a substitute for inorganic fertilizer. RAE values were highest in treatment of O4K2B2 (30 Mg OP ha-1, with inorganic fertilizer, 10 Mg biochar ha-1) that was equal to 181%, followed by O2K2B3 (10 Mg OP ha-1, with inorganic fertilizer, 20 Mg biochar ha-1 ) with the difference in RAE value of 0.5%.

Rice is the main staple food in Indonesia. The high needs of national rice must be balanced with the high production of rice crops. One of the efforts to increase the production of rice is the application of liquid smoke originated from agricultural waste, namely husk. The research was aimed to determine the effect of the application of husk liquid smoke on rice growth and production. The research used a single-factor randomized block design (RBD) with 5 treatments and 5 replications. The treatments consisted of several concentrations of liquid smoke : 0% (control), 0.5%, 1%, 2%, and 3%. This research employed several stages; land processing, seedling nursery, rice planting, applicating the liquid smoke, fertilizing, maintaining plants, and harvesting. The results showed that the application of husk liquid smoke significantly affected all observational parameters. On the parameters of rice growth and production, the application of 2% liquid smoke showed the best result. The plant height increased by 25.80% and the number of tillers increased by 49.70% compared to the control. The highest increase is in the number of grains per panicle and the weight of 1000 grains was 4,984% and 26.78% respectively.

ABSTRACT Shallot cultivation in peat land was constrained by the high production costs, especially fertilizer and lime costs (Abdullah, 2011). Therefore, improvement of shallot productivity in peat land was to use local resources so that the production costs would be reduced. Potential material to be used for that purpose was sea mud which abundantly available in West Kalimantan. The productivity of several shallot varieties in peat land had not reached their production potential. The research used Randomized Block Design (RBD) with the treatment of sea mud consisted of without the treatment of sea mud (L0) and with the treatment of sea mud (L1) and several shallot varieties such as Bima Variety (V1), Manjung Variety (V2) and Sumenep Variety (V3). The research result showed that the treatment of sea mud and varieties of shallot differed significantly in improving the growth and production of shallot. Bima, Manjung and Sumenep each produced 14.73 ton/ha, 12.84 ton/ha and 9.22 ton/ha respectively. Based on profit value and B/C ratio value, the utilization of sea mud in peat land was economically feasible to be applied by farmers in West Kalimantan.

Grape Juices

Vitis labrusca grapes are widely cultivated in some countries such as Brazil and the United States, especially for juice production. ‘Isabel’ is one of the main cultivars because of its high production and disease tolerance, but the juice is deficient in color. The objective of this study was to evaluate the effect of timing and concentration of (S)-cis-abscisic acid (S-ABA), a specific isomer of abscisic acid applied to ‘Isabel’ grapes, aiming to increase anthocyanin accumulation and to improve juice quality. The trial was conducted on two consecutive seasons (2011 and 2012) in a commercial vineyard located in Maringa, PR, Brazil. The vines were trained in an overhead trellis system and spaced at 4.0 × 1.0 m. The statistical model used was a randomized block design with four replications and five treatments: control; S-ABA at 200 mg·L−1 at 7 days after veraison (DAV); S-ABA at 400 mg·L−1 at 7 DAV; S-ABA at 200 mg·L−1 at 7 DAV + 200 mg·L−1 at 15 days after the first application (DAFA); and S-ABA at 400 mg·L−1 at 7 DAV + 400 mg·L−1 at 15 DAFA. There were no significant differences between treatments in relation to berry or cluster size or weight. S-ABA application resulted in increased anthocyanin concentrations in both berries and juices, mainly when 400 mg·L−1 was applied. Sensory analysis also revealed the efficiency of this plant growth regulator to promote better acceptance of grape juices. Thus, a single application of S-ABA at 400 mg·L−1 at 7 DAV is sufficient to increase the anthocyanins concentration of ‘Isabel’ grapes, improving the acceptance of juice by consumers.
