| Judul Artikel | PENGARUH PEMBERIAN LARUTAN SALINITAS TERHADAP PERTUMBUHAN DAN HASIL TANAMAN KUBIS (Brassica oleracea var. capitata L.) PADA MEDIA PASIR PANTAI |
| Abstrak (Bhs. Indonesia) | Kubis (Brassica oleracea var. capitata L.) merupakan salah satu tanaman sayuran yang banyak dibudidayakan oleh masyarakat di Indonesia. Namun lahan produktif yang digunakan untuk budidaya kubis semakin menurun. Salah satu upaya untuk meningkatkan produksi kubis yaitu memanfaatkan lahan pasir pantai yang memiliki kandungan garam tinggi (salin). Penelitian ini bertujuan untuk membedakan respon pertumbuhan dan hasil tanaman kubis dengan berbagai cara pemberian larutan salinitas, membedakan respon pertumbuhan dan hasil tanaman kubis pada berbagai konsentrasi larutan salinitas, membedakan respon pertumbuhan dan hasil tanaman kubis dengan berbagai frekuensi larutan salinitas, membandingkan interaksi cara pemberian salinitas, freukeunsi, dan konsentrasi larutan salinitas terhadap pertumbuhan dan hasil tanaman kubis. Penelitian dilaksanakan pada bulan Desember 2021 sampai bulan Mei 2022 di screenhouse Fakultas Pertanian Universitas Jenderal Soedirman. Penelitian ini menggunakan RAKL (Rancangan Acak Kelompok Lengkap) dengan 3 faktor. Faktor pertama yaitu cara pemberian. Faktor kedua yaitu konsentrasi pemberian larutan salinitas. Faktor ketiga yaitu frekuensi pemberian larutan salinitas. Hasil penelitian menunjukkan bahwa cara pemberian larutan salinitas melalui udara lebih mengingkatkan kadar prolin, sedangkan cara pemberian larutan salinitas melalui tanah lebih meningkatkan EC tanah fase vegetatif. semakin meningkatnya konsentrasi larutan salinitas menurunkan variabel bobot kering akar, bobot segar batang, bobot segar daun, klorofil fase generatif, kerapatan stomata fase vegetatif, bobot segar krop, diameter krop, bobot hasil segar krop. Adapun pada variabel prolin dan EC tanah dimana semakin tinggi konsentrasi larutan salinitas akan meningkatkan kadar prolin dan EC tanah. Semakin banyak frekuensi pemberian larutan salinitas menurunkan bukaan stomata fase vegetatif, bukaan stomata fase generatif, kerapatan stomata fase vegetatif. |
| Abtrak (Bhs. Inggris) | Cabbage (Brassica oleracea var. capitata L.) is a vegetable plant that is widely cultivated by people in Indonesia. However, the productive land used for cabbage cultivation is decreasing. One of the efforts to increase cabbage production is by utilizing beach sand land which has a high salt content (saline). The aims of this study were to differentiate the growth and yield responses of cabbage plants to various methods of administration of saline solutions, to distinguish the growth responses and yields of cabbage plants to various concentrations of salinity solutions, to differentiate the growth responses and yields of cabbage plants to various salinity solution frequencies, to compare the interactions of methods of administration of salinity, frequency, and concentration of salinity solution on the growth and yield of cabbage plants. The research was carried out from December 2021 to May 2022 at the Screenhouse of the Faculty of Agriculture, Jenderal Soedirman University. This study used RCBD (Randomized Complete Block Design) with 3 factors. The first factor is the method of administration. The second factor is the concentration of the saline solution. The third factor is the frequency of administration of saline solution. The results showed that the method of administering a salinity solution through the air increased proline levels more, while the method of administering a salinity solution through the soil increased the EC of the vegetative phase of the soil. Increasing the concentration of the salinity solution decreases the variables of dry weight of roots, fresh weight of stems, fresh weight of leaves, chlorophyll generative phase, stomatal density of vegetative phase, fresh weight of heads, head diameter, fresh yields of heads. As for the proline and soil EC variables where the higher the concentration of the salinity solution will increase the proline and soil EC levels. The more frequency of administration of saline solution decreased the vegetative phase stomatal openings, generative phase stomatal openings, stomatal density of the vegetative phase |
