Pertumbuhan dan produksi tanaman kailan (Brassica oleracea) akibat pemberian mulsa jerami padi dengan takaran yang berbeda

Abstract

The objective of this research was to examine the effect and quantity of rice straw mulch on the growth and production of kailan. This research was conducted inAspakusa Makmur Farms Association, Teras, Boyolali and Laboratory of Ecology and Plant Production, Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarangfrom January 24th to March24th 2018. The research was assigned in completely randomized monofactor design with the factor was M0: control, M1: 2 ton/ha, M2: 4 ton/ha, M3: 6 ton/ha and M4: 8 ton/ha. Parameters observed were plant height, number of leaves, soil and temperature, plant and root wet weight, plant and root dry weight and total chlorophyll content.The results showed thatmulch treatment with a dose of 6 tons/ha was able to increase the yield of leaves, root dry weight and total chlorophyll content but did not increase crop yields, soil and temperature, plant and root wet weight, plant dry weight Keyword: Kailan, Mulch, Rice straw ABSTRAK Penelitian bertujuan untuk mengkaji pengaruh dan takaran mulsa jerami padi terhadap pertumbuhan dan produksi tanaman kailan. Penelitian dilakukan pada tanggal24 Januari 2018 – 24 Maret 2018 di Lahan pertanian Asosiasi Aspakusa Makmur Kecamatan Teras Kabupaten Boyolali dan Laboratorium Ekologi dan Produksi Tanaman, Fakultas Peternakan dan Pertanian, Universitas Diponegoro, Semarang. Penelitian disusun dengan rancangan acak lengkap monofaktor dengan perlakuan M0: kontrol, M1: jerami padi 2 ton/ha, M2: jerami padi 4 ton/ha, M3: jerami padi 6 ton/ha dan M4: jerami padi 8 ton/ha. Parameter yang diamati adalah tinggi tanaman, jumlah daun, kelembaban dan suhu tanah, berat basah tanaman dan akar, berat kering tanaman dan akar dan kandungan klorofil total. Hasil penelitian menunjukkan bahwa Perlakuan mulsa dengan takaran 6 ton/ha mampu meningkatkan hasil jumlah daun, berat kering akar dan kandungan klorofil total tetapi tidak meningkatkan hasil tinggi tanaman, kelembaban dan suhu tanah, berat basah tanaman dan akar, berat kering tanaman Kata kunci: kailan, mulsa, jerami padi

The dynamics of changes in soil temperature due to the application of rice straw mulch on lettuce (Lactuca sativa L.)

“…The result not significantly can occur because the thickness of the mulch applied has not been able to significantly reduce the soil temperature [6]. The low dose of rice straw mulch application will cause the intensity of solar radiation that hits the ground to be high so that the temperature and soil moisture are low [7]. Furthermore, when organic mulch begins to decompose, it will not have any effect on temperature or soil moisture [8].…”

Potential of Loss of Organic Fertilizer in Lowland Rice Farming in Klungkung District, Bali

“…This result was the same as the statement of Rosmiza et al (2014b) which states that rice straw was generally used as mulch when growing vegetables and horticulture. The use of rice straw mulch was done by farmers for several reasons such as to suppress the growth of pests, reduce evaporation and reduce the cost of purchasing plastic mulch (Setiyaningrum, 2019).…”

Pengaruh Residu Mulsa Jerami Padi dan Pupuk Organik Plus terhadap Produksi Tanaman Jagung Pulut (Zea mays ceratina Kulesh)

“…Pemberian bahan penutup tanah seperti mulsa dapat menjaga kelembaban dan mencegah tumbuhnya berbagai jenis gulma dan penyakit sehingga tanaman dapat tumbuh dan berkembang dengan baik (Setiyaningrum et al, 2019). Bahan penutup tanah yang memiliki potensi untuk diberikan pada tanaman jagung adalah mulsa jerami, karena memiliki fungsi dalam menekan pertumbuhan berbagai jenis gulma pada lahan tanaman jagung, menjaga air hujan yang jatuh langsung ketanah, menjaga erosi, penguapan, suhu, dan kelembapan tanah (Gustanti et al, 2014).…”

“…Mulsa jerami padi juga lebih ekonomis, membantu penyerapan air dalam tanah. Mulsa jika terurai akan meningkatkan kadar organik tanah (Setiyaningrum et al, 2019). Jerami padi mengandung unsur N sekitar 40%, P 30-35%, K 80-85%, dan unsur S 40-45% (Baka & Tematan, 2020) dan Setiyaningrum et al, (2019) menyatakan dalam jerami mengandung 4-7% unsur Si, 1,2-1,7% K20, 0,07-0,12% P205 dan 0,5-0,8% N. Adanya penutup tanah (mulsa) dapat mencegah tumbuhnya gulma pada tanaman karena dapat mencegah persaingan unsur hara, air dan sinar matahari terutama pada fase pertumbuhan vegetatif (Sari et al, 2021).…”
