Abstract

Beetroot (Beta vulgaris L.) is a horticultural plant that has many benefits that lie in tubers. Red beets are widely planted in highland areas with loose soil conditions. Currently, the expansion of land for food crops is experiencing problems due to limited productive land. The use of dry land as agricultural land has the main obstacles, namely low soil fertility, low organic matter content, and generally clay and dust-dominated soil. The application of organic matter needs to be added aiming to improve the physical properties of the soil, especially soil texture so that the soil becomes loose so that it does not hinder the tuber development process. The research was carried out from April 2020 to August 2020 at the Agro-Techno Park (ATP) Jatikerto garden. The study used a split-plot design with organic material sources as the main plot, namely B1: goat manure, B2: Azolla compost, B3: UB compost, and the time of application as subplots, namely T1: simultaneously planting, T2: 1 month before planting, and T3 : 2 months before planting. Observational data were analyzed using analysis of variance (Test F), if there was an influence between treatments, further tests were carried out using the Honest Significant Difference (BNJ) test. The results showed that the use of UB compost was better applied 1 month before planting because it produced high tuber weight per harvest plot and was more profitable. Based on the results of farming analysis, the use of UB compost with an application time of 1 month before planting is feasible to cultivate with an R/C reaching 3.67.

Abstract

Produksi jagung manis di Indonesia pada tahun 2014 menurut BPS sebesar 8,13 ton tongkol segar/ha, padahal potensi jagung manis dapat mencapai 14 ton/ha. Salah satu faktor penyebab produksi jagung manis meningkat ialah dengan melakukan pengendalian gulma yang tepat. Sebuah percobaan lapang untuk meneliti pengaruh metode pengendalian gulma pada pertumbuhan dan hasil jagung manis. Percobaan dilakukan sejak bulan Agustus hingga Oktober 2021 di lahan percobaan FP-UB di Jatimulyo, Kecamatan Lowokwaru, Kota Malang, Jawa Timur. Percobaan ini dirancang dalam sebuah Rancangan Acak Kelompok (RAK) non faktorial dengan 4 ulangan. Perlakuan metode pengendalian gulma terdiri dari 6, yaitu: Tanpa penyiangan gulma (P0), Penyiangan setiap minggu (P1), Herbisida pra tumbuh (P2), Herbisida pasca tumbuh Hari ke 21 hst (P3), Herbisida pasca tumbuh Hari ke 21 dan 42 hst (P4) dan Herbisida pra tumbuh + Herbisida pasca tumbuh Hari ke 21 hst (P5). Data yang diperoleh di analisis menggunakan ANOVA (Analysis of Varians). Apabila uji F menunjukkan hasil signifikan, maka analisis dilanjutkan dengan uji Beda Nyata Jujur (BNT) pada taraf 5%. Hasil penelitian menunjukkan bahwa perlakuan herbisida pra tumbuh (P2)  memberikan hasil produksi yang optimal dan memiliki nilai berbeda nyata dengan perlakuan herbisida pasca tumbuh dan tanpa penyiangan. Perlakuan tersebut meningkatkan hasil dari 6,58 ton ha-1 menjadi 21,05 ton ha-1 atau 68,74% lebih tinggi dibandingkan perlakuan tanpa penyiangan. Kegiatan budidaya jagung manis menggunakan perlakuan herbisida pra tumbuh memiliki nilai B/C ratio 1,91 sehingga menguntungkan dan layak diaplikasikan pada usaha tani.
