Pengaruh dosis kascing dan bioaktivator terhadap pertumbuhan dan hasil tanaman sawi (Brassica juncea L.) yang dibudidayakan secara organik

Abstract

Sari. Peningkatan produktivitas sawi (Brassica juncea L.) dapat dilakukan secara organik. Tujuan penelitian ini untuk mengetahui pengaruh dosis kascing dan penggunaan bioaktivator terhadap pertumbuhan dan hasil tanaman sawi. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK), terdiri atas sembilan kombinasi perlakuan dan diulang empat kali, masing-masing kombinasi perlakuan adalah: tanpa kascing dan tanpa bioaktivator; kascing 5 ton/ha dan tanpa bioaktivator; kascing 5 ton/ha dan bioaktivator 4 mL/L; kascing 10 ton/ha dan tanpa bioaktivator; kascing 10 ton/ha dan bioaktivator 4 mL/L; kascing 15 ton/ha dan tanpa bioaktivator; kascing 15 ton/ha dan bioaktivator 4 mL/L; kascing 20 ton/ha dan tanpa bioaktivator; serta kascing 20 ton/ha dan bioaktivator 4 mL/L. Hasil penelitian menunjukkan bahwa pemberian pupuk kascing dan bioaktivator memberikan pengaruh yang nyata terhadap tinggi tanaman, jumlah daun, berat basah tanaman, dan berat kering tanaman dibandingkan dengan tanpa pemberian kascing dan bioaktivator. Dosis pupuk kascing 5 ton/ha tanpa bioaktivator merupakan dosis yang dianjurkan karena memberikan tinggi tanaman, jumlah daun, berat basah, dan berat kering yang sama dibandingkan dengan perlakuan lainnya yang diberi pupuk kascing dan bioaktivator pada dosis yang lebih tinggi.Kata kunci: Pupuk Kascing, Bioaktivator, Tanaman Sawi, Budidaya Organik Abstract: Brown mustard yield can be increased based on organic farming. The purpose of this study was to determine the effect of vermine compost dose and bioactivactor application on the growth and yield of brown mustard. The experimental design used Randomized Block Design. There were nine treatments: without vermi manure and without bioactivator; vermi manure 5 ton/ha and without bioactivator; vermi manure 5 ton/ha and bioactivator 4 mL/L; vermi manure 10 ton/ha and without bioactivator; vermi manure 10 ton/ha and bioactivator 4 mL/L; vermi manure 15 ton/ha and without bioactivator; vermi manure 15 ton/ha and bioactivator 4 mL/L; vermi manure 20 ton/ha and without biactivator; and vermi manure 20 ton/ha and bioactivator 4 mL/L; with four replications. The results of experiment showed that all dosages of vermi manure fertilizer and bioactivator increased the plant height, number of leaves, and biomass of plant. Dosage 5 ton/ha vermi manure without biactivator gave the best result on biomass of plant.Keywords: Vermi Manure, Bioactivator, Mustard Green, Organic Farming

Effect of Vermicompost and NPK Fertilizer on Growth of Long Beans (Vigna sinensis L.)

“…Research whose results are in line with this study, among others, Wahyudin and Irwan (2019) reported that vermicompost fertilizer treatment was able to increase the number of plant leaves. In addition, the application of vermicompost can also increase plant height, wet weight and dry weight of mustard plants.…”

Nano Biochar Coating Methods of Urea Type to Increase the Growth and Yield of Shallot

“…The extensive root system of a plant is essential for its growth, as it stores water and nutrients from the soil for later use in the plant's metabolism. In other words, roots are one of the organs of the plant that help plants grow [19]. If the roots are good, then the growth of other plant parts will develop well too, because the roots can absorb the nutrients plants need.…”

Pengaruh Interval Pengendalian Gulma Pada Pertumbuhan Dan Hasil Dua Varietas Tanaman Kacang Hijau (Vigna Radiata L.)

“…Laju fotosintesis meningkat dapat menyebabkan sintesis karbohidrat juga meningkat. Peningkatan karbohidrat yang disebabkan oleh laju fotosintesis, meningkatkan pertumbuhan vegetatif tanaman termasuk pertumbuhan tinggi tanaman dan pembentukan daun (Wahyudin, 2005). Jika sintesis karbohidrat meningkat, maka kadar gula yang terdapat dalam karbohidrat dari hasil fotosintesis akan meningkat pula.…”
