​Efficient Utilization of Paddy Straw and Sugarcane Bagasse through Vermicomposting and its Impact on Growth, Yield and Quality of Broccoli [Brassica oleracea (var.) italica]

Background: Broccoli [Brassica oleracea (var.) italica] is a cool season vegetable of family cruciferous, known as harigobi in Hindi. In modern agriculture, high doses of chemical fertilizers are used to maximize the crop production. Plenty of chemical fertilizers along with a small quantity of organic ones are being used to increase the yield which ultimately affects the health of soil. Due to excess use of chemical fertilizers a decline pattern is observed in soil fertility, therefore integrated nutrient management is an important demand of present era. Vermicompost application is an important forthcoming addition in this venture. Methods: The research material comprised of seven treatments with three replications. Treatments included FYM (T1), Chemical fertilizer (T2), Paddy straw vermicompost (T3), Sugarcane bagasse vermicompost (T4), Paddy straw+Sugarcane bagasse vermicompost (T5), Vermicompost+Vermiwash (T6) and control (T7). The experiment was conducted considering the growth and yield parameters along with quality parameters. Result: The results indicated that application of treatment T5 vermicompost was found to be the best treatment combination in terms of quality of broccoli. Thus, the study indicates that the vermicompost can be utilized effectively for sustainable crop production.

Pengaruh Pupuk Organik terhadap Pertumbuhan dan Hasil Tanaman Kale (Brassica oleracea acephala) Sistem Vertikultur

Tanaman kale merupakan tanaman suku Brassicaceae atau kubis-kubisan yang kaya vitamin A, vitamin B1, vitamin B2, vitamin B3, vitamin C. Kale juga mengandung senyawa isotiosianat yang memiliki aktivitas antikanker. Penelitian dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Respati Indonesia pada bulan Februari sampai dengan Agustus 2021. Rancangan yang digunakan adalah Rancangan Acak Kelompok dengan satu faktor yaitu jenis pupuk organik terdiri dari empat perlakuan yaitu pupuk NPK, kulit bawang merah, kotoran kelinci, kotoran burung. Setiap perlakuan diulang lima ulangan, sehingga diperoleh 20 unit percobaan. Variabel penelitian meliputi tinggi tanaman, jumlah daun, berat akar, panjang akar, diameter batang, dan berat basah tanaman. Hasil penelitian menunjukkan bahwa pupuk organik berpengaruh nyata terhadap tinggi tanaman, berat akar dan dan berat tanaman kale. Pupuk organik kotoran burung menghasilkan tinggi tanaman tertinggi yaitu 25,50 cm tetapi berbeda tidak nyata dengan kotoran kelinci. Berat akar dan berat basah tanaman kale tertinggi dihasilkan perlakuan kotoran kelinci masing-masing yaitu 2,28 gram dan 30,37 gram serta berbeda nyata dengan perlakuan lainnya.
