Ubi jalar (Ipomoea batatas L) merupakan tanaman yang dapat berpotensi pengganti beras sebagai makanan pokok. Upaya yang dapat dilakukan dalam meningkatkan hasil produksi ubi jalar dengan memenuhi unsur hara seperti dilakukan pemupukan kalium, serta pembalikan batang yang bertujuan mencegah dihasilkannya umbi disetiap ruas. Tujuan penelitian ini yaitu untuk mengetahui pengaruh berbagai dosis pupuk kalium dan waktu pembalikan batang serta interaksinya terhadap pertumbuhan dan hasil tanaman ubi jalar. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan faktor pertamaya yaitu dosis kalium (KCl) : 50 kg ha-1 (k1), 100 kg ha-1 (k2), dan 150 kg ha-1 (K3). Faktor keduanya yaitu waktu pembalikan batang yaitu: tanpa pembalikan (wo), 4 mst dan 8 mst (w1), 8 mst dan 12 mst (w2). Analisis data pengamatan menggunakan ANOVA dengan uji lanjut BNT dengan p < 0,05. Hasil penelitian menunjukkan bahwa berbagai dosis pupuk kalium memberikan pengaruh yang berbeda-beda pada pertumbuhan tanaman ubi jalar. Diketahui bahwa dosis pupuk KCl 50 kg ha-1 memberikan pengaruh terbaik yaitu memberikan jumlah akar terbanyak dan berat berangkasan basah tertinggi. Pada waktu pembalikan batang diketahui waktu pembalikan 4 MST dan 8 MST memberikan pengaruh terbaik yaitu meningkatkan berat berangkasan kering tertinggi, serta tidak terdapat interaksi antara dosis pupuk kalium dengan waktu pembalikan batang terhadap pertumbuhan dan hasil tanaman ubi jalar.

Tatsoi is included in the Brassicaceae family which contains protein, fat, fiber, calcium and several vitamins making the tatsoi an exclusive vegetable. Tatsoi is not widely cultivated by farmers, so there are not many guidelines for the cultivation. To increase the growth and yield of tatsoi can be done using mulch and Liquid Organic Fertilizer. This study aims to determine effect of the thickness of rice straw mulch and variations concentration of liquid organic fertilizer on the growth and yield of tatsoi. The research was conducted at the STIPER Dharma Wacana experimental garden from November to December 2018. This study used a randomized block design in two factors. The first factor is the thickness of straw mulch which consists of 3 levels (without mulch, rice straw mulch 10 tonnes/ha, and rice straw mulch 20 tonnes/ha). The second factor is the concentration of liquid organic fertilizer which consists of 3 levels (control, 2 ml / l, and 4 ml / l). The results showed that the thickness of the rice straw mulch had no significant effect on the growth and yield of Tatsoi. The addition of 2 ml / l and 4 ml / l liquid organic fertilizer significantly increased the growth and yield of tatsoi compared without liquid organic fertilizer as indicated by the variables of plant height, number of leaves, crown diameter, yield per plot, wet weight salable yield, and yield per hectare. There is no interaction between the two factors.

Dragon fruit is one type of plant that is quite popular in Indonesia because of its sweet taste and high selling price. Dragon fruit has various types, including dragon fruit with red flesh, white flesh with yellow skin color and red skin with white flesh. Dragon fruit contains high betacharotene and antioxidants to prevent cancer and ward off free radicals. The fiber content in it can facilitate digestion, prevent colon cancer, and cope with diabetes. The objectives of this study were to determine effect of length stem cuttings on the growth of red dragon fruit cuttings, effect of different methods of giving between immersion and watering coconut water on the growth of dragon fruit cuttings, and interaction lengths cuttings and how to give coconut water to the growth of dragon fruit cuttings. The results showed that red dragon fruit stem lengths of 25 cm and 30 cm give better results than 15 cm and 20 cm. Dragon fruit stem lengths of 25 cm and 30 cm had a significant effect on bud emergence variables, number of shoots, average shoot length per cuttings and number of roots, but the root length variables, root wet weight and root shoot ratio were not significantly different. The method of giving coconut water shows that watering is better than soaking. but on the variable number of shoots per cuttings, the average length of shoots per cuttings, root wet weight and root crown ratio had no significant effect. There is no interaction between rod length and means giving coconut water to the growth of red dragon fruit cuttings on all observed variables.

Kailan (Brassica oleracea var winsa kaelan sharp leaf) is vegetable can grow on all types of soil, enjoyed by the community so it has good prospects to be developed in Indonesia. Good Cultivation technique the production of kailan. Therefore, the use of liquid organic fertilizer combination with the composition of planting media needs to be applied as both can increase the product of kailan that is organic so that the needs of healthy vegetables can be completed. The purpose of this study are determine the best concentration of liquid organic fertilizer for growth and yield of kailan vegetables, the best planting media for growth and yield of kailan vegetables, and the interaction between of liquid organic fertilizer application and media type of planting toward the growth of kailan vegetables. The results of this research that the concentration of liquid organic fertilizer has no significant effect on growth and yield of kailan, the composition of different planting media has no significant effect on growth and yield of kailan except on the large ratio of leaf (RLD) and wet weight on kailan plant. and there is no interaction between liquid organic fertilizer and plant media composition on growth and yield of kailan plants.
