Effect of tiling system spacing and number of seeds per hole on growth and yield of kale land (Ipomoea reptans Poir.).

This study aims to determine the best spacing and the most effective number of seeds per hole against kale land (Ipomoea reptans Poir). This research was carried out in an experimental area located at Jalan Bunga Cempaka, Tanjung Sari, Medan Selayang District, Medan with an altitude of ± 32 meters above sea level from March to April 2022. This study used a factorial randomized block design, with 2 treatment factors. namely : Planting Distance (J1 : 10 x 10 cm, J2 : 15 x 15 cm, J3 : 20 x 20 cm) and number of seeds per hole (B1 : 1 seed, B2 : 2 seed, B3 : 3 seed, B4 : 4 seed). The results of this study showed that treatment with the tiled spacing system significantly increased plant height, increased root wet weight, and increased plant wet weight per plot. The best results for all these parameters were at a spacing of 15 x 15 cm. Treatment of the number of seeds per planting hole significantly increased the number of leaves that grew and the wet weight of the crown. The best results for all these parameters were treated with 4 seeds per hole. The interaction between the spacing of the tile system and the number of seeds per hole gave unrealistic results for all observation parameters
