2024-01-24T12:02:34+07:00

Introduction: The purpose of this study was to determine the response of tomato plants (Solanum licopersicum) to the administrationof liquid organic fertilizer cow urine and phosphorus fertilizers on andisol soil.
Materials and Methods: This 'research' was carried out in October 2022 – January 2023 in Selayang village, Finish district, with an altitude of 28 meters above sea level. This study used a factorial randomized block design with 2 treatment factors. The firstfactor is cow urine liquid organic fertilizer with Symbol (A) which consists of 2 treatment levels, namely: A0 = (0 ml), A1 = ( 60 ml). The second factor was the application of phosphorus fertilizer symbol (P) which consisted of 4 treatment levels, namely: P0 (without fertilizer), P₁ (125kg P/Ha ≈ 1,7gSP-36/polybag), P₂(250kg P/Ha ≈ 3,5 gSP-36/ polybag) dan P₃ (375kg P/Ha ≈ 5,2 gSP-36/polybag).
Results: The results showed that the treatment of cow urine liquid organic fertilizer (POC) had a very significant effect on the parameters of plant height aged 56 HST, yield and production of tomato plants with the best treatment found in A1 (60 ml). The aplication of phosphorus fertilizer had a significant effect on soil pH and available-P with the best treatment P1 (125kg P/Ha ≈ 1,7 g SP-36/polybag). The interaction of cow urine liquid organic fertilizer (POC) and phosphorus fertilizer had a very significant effect on the yield and production of tomato plants with the best combination treatment A₁P₁ (60 ml) (125kg P/Ha ≈ 1,7 g SP-36/polybag).

Faktor pertama adalah Konsentrasi pupuk organik cair HANTU yang terdiri dari 4 level, yaitu 0 ml/liter air, 2 ml/liter air, 4 ml/liter air dan 6 ml/liter air. Faktor kedua adalah Waktu Aplikasi pupuk organik cair HANTU yang terdiri dari 3 level, yaitu 5 HST, 10 HST dan 15 HST. Data yang diperoleh dianalisa menggunakan tabel Anova.

Berdasarkan hasil analisa sidik ragam menunjukkan tidak adanya interaksi antara Konsentrasi dengan Waktu Aplikasi pupuk organik cair terhadap tinggi tanaman, jumlah daun dan diameter batang tanaman jagung di semua umur pengamatan, namun pada faktor tunggal Konsentrasi pupuk organik cair menunjukan pengaruh terhadap variabel pengamatan tinggi tanaman dan jumlah daun tanaman jagung. Tinggi tanaman terbaik terdapat pada perlakuan konsentrasi 6 ml, dan jumlah daun terbaik terdapat pada perlakuan konsentrasi 6 ml. Sedangkan pada variabel diameter batang tanaman tidak menunjukan perbedaan yang signifikan. Pada variabel pengamatan fase generatif menunjukan adanya interaksi sangat nyata antara Konsentrasi dengan Waktu Aplikasi pupuk organik cair terhadap berat 1000 biji. Berat 1000 biji terbesar ditunjukan oleh perlakuan kombinasi konsentrasi 6 ml dengan waktu aplikasi 15 HST dengan nilai 332.267 gr. Sedangkan pada variabel panjang tongkol, berat tongkol berklobot dan berat tongkol tanpa klobot hanya menunjukan pengaruh pada faktor tunggal Konsentrasi pupuk organik cair.

2024-01-23T16:49:35+07:00

Palm oil (Elaeis guineensis Jacq.) is commodity the largest contributor to the country's foreign exchange the production of palm oil and palm kernel oil. Efforts made to ensure optimal absorption of air and nutrients during the nursery is apply Trichoderma. Trichoderma has the ability to produce anti-microbial metabolites, mycoparasites, and the ability compete with pathogenic fungi. The antagonistic Trichoderma used as an environmentally friendly alternative for controlling pathogens. N, P, and K are needed in the photosynthesis process constituents of compounds in plants that will be converted to form plant organs such as leaves, stems, and roots. The availability of n, p, and k for plants can increase the amount of chlorophyll, increasing chlorophyll will increase photosynthetic activity which produces more assimilate which supports plant dry weight. This research used a factorial randomized block design (RAK) with 2 treatment factors. The first factor is the Trichoderma which consists of 2 treatment levels, J1 = Trichoderma 10 gr/plant, J2 = Trichoderma 15 gr/plant. The second factor of NPK fertilizer consists of 3 treatment levels, P0 = Control, P1 = 8 grams, P2 = 10 grams. The parameters in this research's plant height, number leaves, stem diameter and leaf area. NPK had a significant on the number leaves and leaf area, the best treatment was P2. Trichoderma had a significant on the number of leaves, stem diameter and leaf area, the best treatment was J2. The interaction of trichoderma and NPK had a significant on leaf area, the best treatment was J2P2.
