Abstract

Abstrak: Konsumsi tomat (Solanum esculentum Mill.) di Indonesia mengalami peningkatan pada setiap tahunnya seiring dengan bertambahnya jumlah penduduk di Indonesia. Namun demikian, produktivitas tanaman tomat secara nasional masih perlu ditingkatkan. Upaya yang perlu dilakukan adalah dengan menggunakan komposisi media tanam dan pupuk organik yang sesuai untuk memenuhi kebutuhan unsur hara yang dibutuhkan tanaman tomat serta memperbaiki sifat fisik, kimia, dan biologi tanah. Penelitian dilaksanakan pada bulan Juni-Oktober 2022 di Rumah Kaca yang terletak di Desa Malasan Kulon dengan ketinggian 800 mdpl. Penelitian ini bertujuan untuk mengetahui pengaruh komposisi media tanam dan dosis vermikompos terhadap pertumbuhan dan hasil tanaman tomat. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktor, yaitu komposisi media tanam dan dosis vermikompos yang dilakukan sebanyak tiga kali. Faktor 1 adalah komposisi media tanam yang terdiri dari M0: tanah; M1: tanah: arang sekam: cocopeat (2:1:1); M2: tanah: arang sekam: cocopeat (1:2:1); M3: tanah: arang sekam: cocopeat (1:1:2). Faktor 2 adalah dosis vermikompos yang terdiri dari V0: kontrol; V1: 200 gram; V2: 300 gram; V3: 600 gram. Hasil penelitian menunjukkan bahwa interaksi komposisi media tanam dan dosis vermikompos berpengaruh terhadap pertambahan tinggi tanaman dan diameter batang. Komposisi media tanam sebagai faktor tunggal berpengaruh terhadap jumlah bunga, diameter batang, diameter buah, total produksi, tinggi tanaman, berat basah tanaman, dan jumlah buah. Dosis vermikompos sebagai faktor tunggal berpengaruh terhadap semua variabel yang diamati. Kombinasi terbaik terdapat pada komposisi media tanam tanah : arang sekam : cocopeat (2:1:1) dengan dosis vermikompos 600 gram/polybag.

Abstract

Porang plants (Amorphophallus muelleri Blume) are herbaceous plants that are commonly found growing wild in forested areas, under bamboo clumps, along riverbanks, on mountain slopes, amidst dense and humid vegetation. Porang propagation from corms and cormels requires a considerable amount of time, around 7-9 months. Therefore, there is a need for the development of porang seedlings through easy vegetative propagation methods that can be implemented at the farmer level. This research utilized Entisol soil originating from Andalan Village, Bayan Subdistrict, North Lombok Regency. The research was conducted using an experimental method. The treatments were arranged using a Completely Randomized Design (CRD) involving 4 seed sources (porang cormels/bulbils, split corms, porang leaves, and porang stems) with 3 treatments, namely no treatment, biochar, liquid organic fertilizer, PGPR, and Trubus plant growth regulator. The analysis of variance results showed that the application of various growing media (biochar, liquid organic fertilizer, and PGPR) influenced changes in soil properties and the growth of porang seedlings. The growth of porang seedlings was influenced in the split corm and cormel techniques. Further tests indicated that the cormel technique, specifically in terms of plant height and stem diameter, was affected by the addition of organic materials compared to the absence of organic material application

Abstract

Problems with Entisol soil fertility in the Dry Land of North Lombok Regency, which is dominated by sandy soil. This is a major factor in carrying out agricultural production activities on dry land in the North Lombok region. One of the efforts that must be made to increase soil fertility is by modifying the root area through the addition of soil amendments such as manure and cocopeat. The purpose of this study was to determine the growth response of sorghum plants to the application of cocopeat combined with cow manure in dry land. The method used in this research is an experimental method with field experiments. The experimental design in this study used a randomized block design (RBD) with 5 treatments, P0 (soil/control), P1 (100 kg/ha silicate fertilizer), P2 (10 tonnes/ha manure + 100 kg/ha silicate fertilizer), P3 (10 tons/ha cocopeat + 100 kg/ha silicate fertilizer), P4 (10 tons/ha manure + 10 tons/ha cocopeat + 200 kg/ha silicate fertilizer). Each treatment was repeated 4 times to obtain 20 experimental units. The effect of giving a combination of manure and cocopeat on sorghum plants showed significant results on plant height and plant stem diameter at each observation, namely at plant ages 25, 32, 39 and 46 HST.
