Abstract

Sweet corn is a commodity for seasonal crops and food crops. In addition, this plant is also included in the cereal plant and is widely eaten by residents after rice plants. Sweet corn has a sweeter taste than other corn, so it is usually eaten when still young. The experiment was aimed to determine the interaction between several types and concentrations of armyworm insecticides on the growth and production of sweet corn plants. It was conducted at the Faculty of Agriculture, Kadiri University, from February to March 2021. The experimental design used in this study was a 5 x 2 factorial randomized block design with three replications. 2 factors were examined, namely the type of insecticide and the concentration of insecticides. Research results showed a combination of treatment and insecticide concentration of armyworm pests. There was an interaction with the sweet corn stalk diameter parameters. The best treatment was found in the Sidasat Insecticide (M4) with a concentration of 1gr/l. And found in the results of the study of giving a combination of insecticide treatment and the concentration of armyworms at the age of 30SHT, the best treatment was found in the combination treatment of chemical insecticides (M4K1) Sidasat with a concentration of 1gr/ which is 11.96% pest attack rate on corn plants. The combination of treatments and concentration of armyworm insecticide solution on maize showed no interaction with the cob's length, diameter, and weight. The combination of insecticide treatment and dose did not affect the production of sweet corn.Jagung manis memiliki ciri kas rasa yang lebih manis dari pada jagung yang lain. Komoditas jagung manis tergolong tanaman semusim dengan umur yang sangat pendek, sehingga dalam budidayanya diperlukan penanganan lebih extra, terutama pada kegiatan pengendalian hama. Keberadaan hama baru Spodoptera frugiperda berpotensi dalam menurunkan produksi jagung karena intensitas serangannya sangat cepat. Percobaan ditujukan untuk mengetahui interaksi antara beberapa macam dan konsentrasi insektisida hama ulat grayak, terhadap pertumbuhan dan produksi tanaman jagung manis. Uji coba dilakukan di lahan percobaan Fakultas Pertanian Universitas Kadiri. Rancangan percobaan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) pola faktorial 5x2, dengan 3 ulangan. Faktor pertama adalah macam isektisidaM1= Bt Plus (Bacillus sp), M = Metarizep (Bauveria s.), M =Proclaim (Emmamectin Benzoat 5%) M4= Sidasat (Asefat 75%) M5= Winder (Imidakloprid 75%). Faktor kedua konsentrasi larutan insektisida (K), yaitu: K1= 1 gr/liter K2= 3 gr/liter. Hasil penelitian menunjukkan kombinasi perlakuan macam dan konsentrasi insektisida hama ulat grayak terjadi interaksi terhadap parameter panjang, diameter, dan bobot tongkol jagung manis. Perlakuan terbaik pada insektisida sidasat (M4). Kombinasi perlakuan insektisida kimia (M4K1) sidasat dengan konsentrasi 1gr/ dapat menurunkan intensitas serangan hama ulat gerayak hingga 11,96%.

Abstract

This study was aimed to determine the response of shallot productivity due to the treatment of varieties and tuber weight. The study was conducted using a completely randomized design (CRD) consisting of 2 factors with three replications. The first factor (type) consists of 3 levels, namely Bauji (V1), Title (V2), and Philip (V3). The second factor (tuber weight) consists of 3 levels, namely small size 5 grams (U1), medium size 10 grams (U2), and large size 15 grams (U3). The data obtained were analyzed by a variety test and a further test of the least significant difference (LSD). In the parameters of plant height and number of leaves, there was no interaction between the two factors, but the highest value for each parameter was obtained by treatment U2 (52.96 cm) and V2 (32.66 pieces), respectively. The number of bulbs did not show a positive response between the two treatments. In contrast, the wet and dry weights interacted positively with the maximum results obtained in the V2U2 treatment, respectively, namely 40.66 grams and 10.16 grams. Penelitian ini bertujuan untuk mengetahui pengaruh macam varietas dan bobot umbi terhadap pertumbuhan dan produksi bawang merah (Allium cepa L.). Penelitian dilakukan menggunakan rancangaan acak lengkap (RAL) yang terdiri dari 2 faktor dengan 3 ulangan. Faktor pertama (macam varietas) terdiri dari 3 taraf yaitu Bauji (V1), Tajuk (V2), dan Philip (V3). Faktor kedua (bobot umbi) terdiri dari 3 taraf yaitu ukuran kecil 5 gram (U1), ukuran sedang 10 gram (U2), dan ukuran besar 15 gram (U3). Data yang diperoleh dianalisis dengan uji ragam dan uji lanjut beda nyata terkecil (BNT) 5%. Pada parameter tinggi tanaman dan jumlah daun tidak terjadi interaksi antar kedua faktor namun nilai tertinggi untuk masing masing parameter secara berurut diperoleh oleh perlakuan U2 (52,96 cm) dan V2 (32,66 buah). Jumlah umbi tidak menunjukkan respon positif yang terjadi antara kedua perlakuan , sedangkan pada berat basah dan berat kering terjadi interaksi respon positif dengan hasil maksimum diperoleh perlakuan V2U2 secara berurut yaitu 40,66 gram dan 10,16 gram.
