Abstract

The intensity of the shade and fertilizer are the two aspects of the environment that important for the growth of madeira vine plants. The purpose of the research was to know the growth response of madeira vine on different levels shade and application of fertilizer and Biochar. The research was conducted in the research field of Faculty of Agriculture, Universitas Sumatera Utara, Medan about ± 32 m above the sea, on June to August 2017. This research used Split Plot Design with 2 factors, level of shade (0%; 25%; 50%; dan 75%) and application Fertilizer (without fertilizer; urea 1.6 g/plant; chicken manure 53.3 g/plant; biochar rice husk 294.4 g/plant). This results research showed that without shade (0%) increased the growth of plant length but the 75% shade increased of chlorophyll a, chlorophyll b, and total chlorophyll. Application of chicken manure was increasing plant length, shoot fresh weight but application biochar rice husk increased crop dry weight and leaf area. The interaction of different level shade and application of fertilizer was not significant affecting to the growth madeira vine plant in the end of observation.

Abstract

Penelitian ini bertujuan untuk mengetahui respons pertumbuhan vegetatif binahong terhadap aplikasi pupuk organik cair. Penelitian ini dilaksanakan di Lahan Praktikum Fakultas Pertanian Universitas Sumatera Utara, Medan, pada bulan Januari 2017 hingga April 2017. Metode penelitian menggunakan Rancangan Acak Kelompok non faktorial dengan 6 taraf perlakuan, yaitu : 0; 2,5; 5,0; 7,5; 10,0 dan 12,5 ml/l. Parameter yang diamati adalah Panjang tanaman, jumlah daun, bobot segar tajuk, bobot kering tajuk, bobot segar akar, dan bobot kering akar. Hasil penelitian menunjukkan bahwa pemberian pupuk organik cair dengan konsentrasi 12,5 ml/l memberikan pengaruh nyata meningkatkan pertumbuhan panjang tanaman dan jumlah daun. Pemberian pupuk organik cair dengan konsentrasi 12, 50 ml/l, 2,50 ml/l, 5,00 ml/l, 7,50 ml/l, dan 10 ml/l memberikan pengaruh tidak nyata terhadap konsentrasi pada bobot segar tajuk. Pemberian pupuk organik cair dengan konsentrasi 7,50 ml/l memberikan pengaruh nyata meningkatkan pertumbuhan bobot segar akar dan bobot kering akar.

Abstract

The low productivity of soybean in Indonesia was caused by natural factors, biotics, cultivation techniques and soybean plant physiology. Extensification program to meet the needs of soybeans can be solved by using dry land, of drought stress. The study was conducted at the Screen house Faculty of Agriculture, Universitas Sumatera Utara, Medan (± 32 meters above sea level), on July to October 2017, using a randomized block design with 2 treatment factors. The first factor is drought stress with 3 levels ie 80% ; 60% and 40% field of capacity(FC) . The second factor is an ascorbic acid with 4 levels of concentration ie: 0 ; 100 ; 200 and 300 ppm.. The observed of variables ie number of leaves, total leaf area, dry seed weight per plant, 100 seed weight and harvest index. The results showed that the increased treatment of drought stress (80 – 40% FC) had the significant on all observed variables. The Ascorbic acid treatment no significant on all observed variable with the average number of leaves and the highest total leaf area at use 200 ppm ascorbic acid and the lowest at control treatment. The interaction no significant on all observed variable.
