Abstract

Salah satu faktor yang mempengaruhi dalam penurunan hasil dan kualitas ubi jalar adalah serangan hama Cylas formicarius. Cendawan entomopatogen Lecanicillium lecanii merupakan salah satu agens hayati yang dapat digunakan untuk mengendalikan berbagai jenis serangga hama. Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi cendawan entomopotagen L. lecanii untuk mengendalikan imago C. formicarius. Metode yang digunakan adalah metode eksperimen dan rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) faktor tunggal yang terdiri dari 4 perlakuan dalam 6 kali ulangan : Kontrol (Aquades); 106 konidia/ml; 107 konidia/ml; 108 konidia/ml. Pengamatan dilakukan setiap hari selama 10 hari setelah aplikasi (hsa) dengan menghitung 10 imago C. formicarius yang mati akibat disemprot dengan suspensi cendawan L. lecanii sebanyak 1 ml/perlakuan. Hasil penelitian menunjukkan bahwa kerapatan konidia L. lecanii 108 konida/ml memberikan hasil paling efektif terhadap mortalitas C. formicarius sebesar 50% dengan nilai LT50 sebesar 10,024 hari. Dengan demikian, cendawan entomopatogen L. lecanii sebagai agens hayati C. formicarius layak untuk dikembangkan lebih lanjut.

Abstract

Spodoptera frugiperda is a new invasive pest that can cause losses in corn production, so control measures are needed to suppress its population. The purpose of this study was to obtain the best concentration of botanical pesticide from soursop leaves extract against the fall armyworm (S. frugiperda). The method used is experimental method using a single factor Completed Randomized Design (RAL) consisting of 7 treatments with 4 replications: A (Control); B (Insecticide deltamethrin 1 ml/lt); C (A. muricata leaves extract 20 gr/lt); D (A. muricata leaves extract 30 gr/lt); E (A. muricata leaves extract 40 gr/lt); F (A. muricata leaves extract 50 gr/lt); G (A. muricata leaves extract 60 gr/lt). The treatment effect was analyzed with Analysis of Variance (ANOVA). If the 5% level F test showed significant results, then it proceeded with the DMRT (Duncan Multiple Range Test) further test at a 5% significance level to determine the best treatment. The results achieved from this study were the concentration of soursop leaves extract 60 gr/lt was able to cause 50% mortality of S. frugiperda in less than one day based on the analysis of probit LT50, inhibiting the larvae from stopping eating with a percentage of 75% at 1 Day After Application (DAA), gave the highest mortality of 85% in 3 DAA. A. muricata leaves extract with a concentration of 60 g/lt was recommended to be used because it gave the best results that were not significantly different from the use of synthetic insecticides against S. frugiperda.

Abstract

Green mustard (Brassica juncea L.) is a vegetable plant that is much needed by the community. One of the factors causing the decline in mustard greens production is due to the community's need for mustard greens which is quite high along with population growth which continues to grow and the harvested area for mustard greens is decreasing. The development of mustard greens produced generally still uses inorganic fertilizers so that it is not yet oriented towards organic products or manure. Quail droppings can cause environmental pollution so that it becomes a solution to be used as manure. This study aims to obtain a combination of doses of manure, quail manure and NPK which gives the highest yield for the growth and yield of mustard greens (Brassica juncea L.) Tosakan F1 variety. The research was carried out in an experimental field located at Jalan DarmaBakti, Curug Village, Kiara Residence, West Bogor District, Bogor City. The research site is located at an altitude of 195 meters above sea level. The research took place from December 2021 to February 2022. The research method used was a single factor Randomized Group Design (RBD) consisting of 9 treatments and 3 replicates: A (Control), B (15 tons/ha of manure), C (250 kg /ha NPK), D (5 tons/ha manure + 200 kg/ha NPK), E (10 tons/ha manure + 200 kg/ha NPK), F (15 tons/ha manure + 200 kg/ha NPK), G (5 tonnes/ha of manure + 150 kg/ha of NPK), H (10 tonnes/ha of manure + 150 kg/ha of NPK) and I (15 tonnes/ha of manure + 150 kg/ha of NPK). Data were analyzed using the F-test analysis at the 5% level if there was a significant effect followed by the DMRT (Duncan Multiple Range Test) advanced test at the 5% level. The results of this study showed no significant effect of giving a combination dose of quail manure and NPK on the growth and yield of mustard greens (Brassica juncea L.) of the Tosakan F1 variety. Keywords: Mustard green variety Tosakan F1, quail manure fertilizer, NPK fertilizer.

Abstract

Seeds with superior quality can reduce the level of disease and pest attacks and can increase production yields. This research aims to determine differences in resistance of several lines of sweet corn (Zea Mays Var. saccharata Sturt) based on armyworm pest resistance. This research was carried out in one of the lands of Kalihurip Village, Cikampek District, Karawang Regency. The experiment will start from February 2024 to May 2024. The method used is experimental, using a single factor Randomized Block Design (RAK) consisting of 10 treatments and repeated 3 times, so that 30 experimental units are obtained. consisting of: SR1 (MS-UNSIKA- profilik), SR2 (SR-3 Sweet Boy F2), SR3 (SR-1 Latan), M6 (M6 gamma ray radiation dose 200 gy), M9 (M9 gamma ray radiation dose 200 gy ), M10 (M10 gamma ray radiation 200 gy), G11 (F2 mutant Talent variety), G12 (S1 Maestro variety), G13 (F2 Talent variety), G14 (F2 Bonanza variety). The experimental results will be tested using the F test, if there is a real effect then it will be tested further by the Duncan Multiple Range Test (DMRT) at 5% level. The results of the research showed that there was no real difference in the intensity of armyworm attacks on various lines of sweet corn plants in the treatment of various lines of sweet corn on the intensity of armyworm attacks. The Ms-Unsika strain showed the highest resistance, while Var. Maestro showed the highest susceptibility and there was no real correlation between disease and pest attacks on production results in the parent line of sweet corn (Zea mays Var. saccharata Sturt) MS-Unsika generation M8 mutant. Keywords: sweet corn parent lines, pests, crop yield

Abstract

Sweet corn is a holticultural that has an important role as a national food source. Corn serves as an alternative food after rice that is commonly consumed by people in Indonesia. One of the causes of decreased sweet corn productivity is attack on corn plant disease. Some important disease that attack sweet corn is leaf blight and leaf rust. Use a genetically mutated varieties resistant to these diseases is one of solution to increase sweet corn production caused by disease attack. This study aims to obtain the lowest intensity of important disease and the best production result in the MS-UNSIKA generation M8 sweet corn. The research was conducted in one of the lands of Kalihurip Village, Cikampek sub District, Karawang District, from February 2024 to Mei 2024. The research method used was an experimental method, using a Single Factor Randomized Block Design (RAK) consisting of 6 MS-UNSIKA M8 sweet corn lines and 4 comparison varieties which were repeated 3 times in plots measuring 2 m x 2 m.. The results of the study showed significantly different effects of leaf blight attacks at 42 and 49 HST, and leaf rust disease at 56 and 63 HST. The Maestro and Bonanza varieties are the varieties that have the lowest attacks of leaf blight and rust with an average attack intensity of21.40% and 11.08% respectively. The results of this research also show that there is no correlation between leaf blight attacks on the production of sweet corn lines (Zea mays Var. saccharata Sturt). Keywords: sweet corn, leaf blight, leaf rust, important diseease
