One of efforts to overcome limited land is verticulture or vertical farming. There were two objectives in this research i.e.: 1) to determine the effective and efficient combinations between planting media and verticultural materials for growth of Pakchoy, and 2) to obtain the best combination between planting models and proportion of N, P and K fertilizers to produce optimal yield of strawberry. First experiment was conducted from October to December 2014 in Gresik. Verticultural materials and media were combined into 12 treatments and three replications for Randomized Block Design. Second experiment was conducted in Batu, where horizontal and vertical planting models were used as first factor and composition of fertilizers (0, 25, 50, 75 and 100% NPK fertilizers) as second factor. Result showed that Carpet (verticultural material) and compost (planting media) produced the highest fresh weight and number of leaf for Pakchoy. No interaction between the farming models and fertilizer (N, P, and K) on area and number of leaf of strawberry. Separately, both horizontal and vertical farming models did not effect on leaf area and number of leaf of strawberry. Application of N, P and K showed significant effect on numbers of leaf, yield and quality of strawberry.
Tanaman pegagan memiliki salah satu kandungan bahan aktif penting yaitu asiatikosida. Salahsatu cara untuk meningkatkan kadar asiatikosida tanaman pegagan adalah dengan aplikasi cekaman air dan cendawan mikoriza. Penelitian bertujuan untuk mengetahui pengaruh cendawan mikoriza dan cekaman air terhadap pertumbuhan dan hasil tanaman pegagan untuk meningkatkan kadar asiatikosida. Penelitian secara faktorial dengan rancangan acak kelompok yang diulang tiga kali. Faktor pertama adalah 3 taraf dosis cendawan mikoriza yaitu tanpa cendawan mikoriza, 15 g polibag-1 cendawan mikoriza dan 30 g polibag-1 cendawan mikoriza. Faktor kedua adalah 4 taraf perlakuan cekaman air yaitu 100%, 75%, 50% dan 25% kapasitas lapang. Hasil penelitian menunjukkan terdapat interaksi antara cendawan mikoriza dengan perlakuan cekaman air terhadap pertumbuhan dan hasil tanaman pegagan dalam meningkatkan kadar asiatikosida. Pada tingkat cekaman air 25% kapasitas lapang, perlakuan cendawan mikoriza 15 g polibag-1 dan cendawan mikoriza 30 g polibag-1 menghasilkan jumlah daun per rumpun, luas daun per rumpun, panjang tangkai daun per rumpun, panjang akar per rumpun, rasio tajuk akar dan kadar asiatikosida yang nyata lebih tinggi dibandingkan tanpa pemberian cendawan mikoriza. Pada perlakuan cendawan mikoriza 30 g polibag-1 dengan tingkat cekaman air 50% kapasitas lapang menunjukkan nilai kadar asiatikosida yang nyata lebih tinggi dibandingkan dengan tanpa perlakuan cendawan mikoriza, namun tidak berbeda dengan perlakuan cendawan mikoriza 15 g polibag-1. Kata kunci : cendawan mikoriza, pegagan, cekaman air, asiatikosida.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
