Growth, Net Assimilation and Yield Analysis of Eggplant(Solanum melongena L.): Dosage of Goat Manure and NPK FertilizerThe research was aimed to obtain the dose of goat manure, NPK fertilizer and the interaction in increasing the growth and yield of eggplant. The research was usedthe randomized block design factorial with the first factor (goat manure) such as K0= 0 ton.ha-1, K1= 10 ton.ha-1, K2= 20 ton.ha-1 and the second factor (NPK Mutiara 16-16-16) such as P0= 0 ton.ha-1, P1= 100 ton.ha-1, P2= 200 ton.ha-1, P3= 300 ton.ha-1 with three replications. This research was conducted at Jl. Eka Rasmi, Medan Johor Subdistrict, Medan, North Sumatra from August until October 2019. The parameters such as plant height, leaf area, fresh weight of root and shoot, dry weight of root and shoot, total dry weight, fruitweight.plant-1, fruit weight.plot-1, crop growth rate (CGR), relative growth rate (RGR), and net assimilation rate (NAR) wereanalyzed using the ANOVA and the means were followed by DMRT test at the level of 5% used the IBM SPSS Statistics v.20. The results showed an increase in leaf area, fresh weight of shoot, dry weight of root, dry weight of shoot, total dry weight, and fruit weight.plant-1, of eggplant plant with the increasing dose of goat manure up to 20 ton.ha-1of 23.27%; 35.85%; 17.64%; 16.55%; 16.66%; and 17.18%, respectively compared to untreated except plant height. Growth in leaf area, fresh weight of shoot, dry weight of root, dry weight of shoot, total dry weight, fruit weight.plant-1 and fruit weight.plot-1of eggplant plant were increased with increasing NPK fertilizer dosage up to 300 kg.ha-1of 16.88%; 25.96%; 24.08%; 38.37%; 34.46%; 21.85%; and 19.22%, respectively compared to untreated. The interaction of goat manure with NPK does not significantly affect on the growth and yield of eggplant plant. The CGR, RGR, and NARvalue in the giving of goat manure from 10 until 30 days after planting was higher compared to the application of Mutiara NPK fertilizer.
Introduction: The research was aimed to obtain the dosage of NASA liquid organic fertilizer (LOF), goat manure (GM) and combinations are appropriate to support the growth and yield of wax apple. Materials and Methods: This research was conducted at Payaroba Street, Binjai City, North Sumatra Province from Juni to December 2018. This research used the randomized block design factorial within the first factor was NASA LOF (C0= 0 ml.l-1; C1= 1 ml.l-1; C2= 2 ml.l-1; C3= 3 ml.l-1 in water), and the second factor was GM (K0= 0 kg.polybag-1; K1= 0.5 kg.polybag-1; K2= 1.0 kg.polybag-1; K3= 1.5 kg.polybag-1) using three replications. Parameters were analyzed using the ANOVA and continued with the least significance different at rate of 5%. Results: GM significantly increased the plant height, stem diameter, number of flower, and fruit weight of wax apple along with increasing doses until 1.5 kg.polybag-1 of 11.76%; 16.70%; 12.90%; and 7.55% respectively, and accelerating the flowering of 2.98 days compared to un-treated. The application of NASA LOF significantly increased the plant height, stem diameter, and number of flower by wax apple along with increasing doses until 3 ml.l-1 water by 7.51%; 46.61%; and 11.04%, and accelerating the flowering of 5.16 days compared to un-treated. The combination of NASA LOF at 2 ml.l-1 water and GM at 1.5 kg.polybag-1 significantly increased the stem diameter by 52.89% compared to the control combination. However, it did not show a significant effect on plant height, flowering, number of flower, and fruit weight of wax apple.
Tujuan penelitian ini untuk mengetahui efektifitas pupuk NPK dan kompos tankos kelapa sawit dapat meningkatkan pertumbuhan bibit kelapa sawit (Elaeis guineensis Jacq) di pembibitan awal. Penelitian dilakukan menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan dua taraf yaitu faktor pertama: pupuk NPK Mutiara 16-16-16 dengan 3 taraf yaitu P0= tanpa pupuk NPK, P1= NPK Mutiara 2 g/polybag P2= NPK Mutiara 4 g/polybag, Faktor kedua: kompos Tandan Kosong Kelapa Sawit dengan 4 taraf yaitu S0= subsoil, S1= subsoil + kompos TKKS 1:1, S2= subsoil + kompos TKKS 1:2, S3= subsoil + kompos TKKS 1:3. Hasil penelitian menunjukkan bahwa Pemberian pupuk NPK Mutiara 16-16-16 dapat meningkatkan pertumbuhan tinggi tanaman bibit tanaman kelapa sawit di pembibitan awal. Kompos Tandan Kosong Kelapa Sawit (TKKS) belum dapat meningkatkan pertumbuhan tinggi tanaman, luas daun, berat basah tanaman dan berat kering bibit tanaman kelapa sawit di pembibitan awal. Interaksi antara pemberian Pupuk NPK dan pemberian kompos Tandan Kosong Kelapa Sawit belum dapat meningkatkan pertumbuhan tinggi tanaman, luas daun, berat basah tanaman dan berat kering bibit kelapa sawit di pembibitan awal.
Pupuk organik cair mengandung unsur hara baik makro maupun mikro yang dibutuhkan tanaman untuk proses pertumbuhan. Tanaman pisang merupakan tanaman budidaya yang banyak dimanfaatkan untuk peluang usaha tersendiri bagi masyarakat, sehingga mengakibatkan banyak limbah kulit pisang yang dihasilkan. Banyaknya limbah kulit pisang ini dapat menjadi salah satu solusi yang dapat dimanfaatkan masyarakat untuk pembuatan Pupuk Organik Cair (POC). Pengabdian masyarakat ini bertujuan untuk memberikan edukasi mengenai manfaat limbah kulit pisang sebagai pupuk organik cair kepada masyarakat (kelompok tani). Pelatihan pembuatan pupuk organik cair dilaksanakan di Kelurahan Tanah Seribu Kecamatan Binjai Selatan Kota Binjai dengan mitra Kelompok Tani Serba Guna. Metode yang digunakan dalam pelatihan ini terdiri dari metode ceramah dan demonstrasi. Limbah kulit pisang yang sudah diolah menjadi pupuk organik cair bermanfaat bagi pertumbuhan dan perkembangan tanaman, memperbaiki sifat fisik tanah serta menambah unsur hara bagi tanaman budidaya. Kata Kunci : Limbah Kulit Pisang, Pupuk Organik Cair
Penelitian ini bertujuan untuk mengkaji pemanfaatan limbah cair tahu dan pupuk NPKMg terhadap pertumbuhan vegetatif bibit kelapa sawit (Elaeis guineensis Jacq) di pembibitan awal. Penelitian dilaksanakan di Desa Karang Rejo Kecamatan Medan Polonia, Medan. Penelitian dilaksanakan pada Juni sampai September 2015. Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) faktorial terdiri dari dua faktor. Faktor pertama: pemberian pupuk NPKMg dengan 3 taraf : P0= tanpa pupuk NPKMg, P1= pupuk NPKMg 2 g/polibag, P2= pupuk NPKMg 4 g/polibag, P3= pupuk NPKMg 6 g/polibag. Faktor kedua: pemberian limbah cair tahu 4 taraf: L0= tanpa limbah cair tahu, L1= limbah cair tahu 80 ml/polibag, L2= limbah cair tahu 160 ml/polibag, L3= limbah cair tahu 240 ml/polibag. Peubah yang diamati: tinggi tanaman (cm), luas daun (cm2), berat basah tanaman (g), berat kering tanaman (g). Hasil penelitian menunjukkan pemberian pupuk NPKMg menunjukkan berpengaruh nyata pada tinggi tanaman, luas daun, berat basah dan berat kering tanaman. Pemberian limbah cair tahu dan interaksinya berpengaruh tidak nyata pada semua peubah amatan dalam penelitian ini.
