Abstract

Control of Grayak Caterpillar (Spodoptera exigua Hubn) pest by farmers generally is still use synthetic insecticides that have such a negative impact resistance, resurgence, killing natural enemies, increasing residue on crop yields, environmental pollution and health problems for users. One effort to reduce the use of chemical insecticides namely biological control method uses the Spodoptera exigua Nucleo Polyhedro Virus. This research was aimed to know the mortality rate army worm (Spodoptera exigua Hubn) by suspension Spodoptera exigua Nucleo Polyhedro Virus with different concentration. This research was conducted in the laboratory and green house of Vegetable Crops Research Institute at Lembang, Bandung from July until September 2014. This research used Randomized Completely Design (RCD). The result showed that Spodoptera exigua Nucleo Polyhedro Virus was significant to death of Spodoptera exigua. Spodoptera exigua Nucleo Polyhedro Virus concentration showed significant to mortality rates of Spodoptera exigua. In the test stage, the larvae of Spodoptera exigua 2 was the highest stage mortality was caused by infection Spodoptera exigua Nucleo Polyhedro Virus. Method of dipping caterpillars and feed applications were the best treatment because it showed the highest mortality. Pest control Grayak Caterpillar (Spodoptera exigua) in the field could use Spodoptera exigua Nucleo Polyhedro Virus coarse suspension of 10 g L-1 which was applied to the onion crop that was attacked.Keywords: Spodoptera exigua, Spodoptera exigua Nucleo Polyhedro Virus, Onion

Abstract

Lebak is a district in Banten province known as one of center for ginger cultivations. The study aimed to determine the diversity of local ginger plants in Lebak-Banten Regency based on morphological characters, so that kinship relationships between commodities can be seen. The study was conducted from Agustus to October 2021. This study used qualitative and quantitative descriptive methods, consisting of 7 accessions with a total sample of 21 plants from the districts in Lebak Regency as Panggarangan, Malingping, Banjarsari and Gunung Kencana. The data was processed using SPSS. Based on the results, there were 7 similar qualitative characters and 3 different qualitative characters. While there were 8 board quantitative characters (various) and 1 narrow quantitative character (uniform), the closest kinship relationship is found in accessions (B3 and E1) with a coefficient value of 1.576 and the furthest kinship in accessions (A1 and D3) wit a coefficient value of 51.024. The results of the dendogram showed that on a scale of 5 formed 14 groups, on a scale of 10 formed 7 groups, a scale of 15 formed 4 groups, a scale of 20 formed 3 group and a scale of 25 formed 2 group. Therefore, further research is needed to determine the relationship of the local ginger based on molecular analysis.

Abstract

This study aimed to determine the effect of single dose of inorganic fertilizer N,P,K and the type of biological fertilizer on the growth and yield of sweet corn (Zea mays subsp. mays L.). The study was arranged in a randomized block design (RBD) with two factors. The first factor was the dose of single inorganic fertilizer N,P,K, which consisted of 3 levels: D1: 100%, D2: 75%, and D3: 50%. The second factor is the type of biological fertilizer, which consisted of 3 levels: P1: Sinarbio, P2: Kayabio, and P3: Ecofert. The results showed that the application of a single inorganic fertilizer N,P,K at a dose of 75% had a significant effect on the parameters of plant height, number of leaves, stem diameter, number of cobs planted, cob weight with cornhusk, cob weight without cornhusk, and yield potential. The type of biofertilizer Sinarbio has a significant effect on the parameters of plant height, number of leaves, stem diameter, number of cobs planted, number of cobs per plot, cob weight with cornhusk, cob weight without cornhusk, and yield potential. The use of a single dose of inorganic fertilizer N,P,K can be reduced to a dose of 75% of the recommendation for sweet corn plants with the application of biofertilizer Sinarbio.

Abstract

This research aimed to determine the effect of LOF concentration from vegetable waste and a combination of planting media on the growth and yield of pak choy plants (Brassica rapa L.). This research was structured in a Randomized Block Design with two factors. The first factor is the POC concentration which consists of 4 levels, namely P0: 0 mL/L, P1: 37.5 mL/L, P2: 45 mL/L, and P3: 52.5 mL/L. The second factor is the combination of planting media which consists of three levels, namely M1: Soil + Charcoal Husk (50% + 50%), M2: Soil + Compost + Charcoal Husk (40% + 40% + 20%), and M3: Soil + Sand + Charcoal Husk (40% + 20% + 40%). The results showed that POC concentration had a significant effect on fresh weight per plant. The combination of planting media has a significant effect on all observation variables. There was an interaction between the two treatments on plant height, number of leaves and fresh weight per plant.Keyword: pak choy, LOF concentration, growing mediaINTISARIPenelitian ini bertujuan untuk mengetahui pengaruh konsentrasi POC asal limbah sayuran dan kombinasi media tanam terhadap pertumbuhan dan hasil tanaman pakcoy (Brassica rapa L.). Penelitian ini disusun dalam Rancangan Acak Kelompok dengan dua faktor. Faktor pertama adalah konsentrasi POC yang terdiri dari 4 taraf yaitu P0: 0 mL/L, P1: 37,5 mL/L, P2: 45 mL/L, dan P3: 52,5 mL/L. Faktor kedua adalah kombinasi media tanam yang terdiri dari tiga taraf yaitu M1: Tanah + Arang Sekam (50% + 50%), M2: Tanah + Kompos + Arang Sekam (40% + 40% + 20%), dan M3: Tanah + Pasir + Aarang Sekam (40% + 20% + 40%). Hasil penelitian menunjukkan bahwa konsentrasi POC bepengaruh nyata terhadap bobot segar per tanaman. Kombinasi media tanam berpengaruh nyata terhadap semua variabel pengamatan. Terdapat interaksi antara kedua perlakuan terhadap tinggi tanaman, jumlah daun dan bobot segar per tanaman.Kata kunci: pakcoy, konsentrasi POC, media tanam
