Abstract

Strawberries are a plant that has various benefits. The fresh fruit and attractive color make strawberries very popular with all groups (Oktarina et al., 2017). In conventionally grown strawberry plants, flowers and stolons generally appear around 8 weeks after planting (WAP), and one parent plant is only able to produce 3 to 4 stolons. This research was carried out in Sempajaya Village, Berastagi District, Karo Regency, North Sumatra, at an altitude of 1,000–1,300 meters above sea level. This research was started in June–August 2023. The research method used was a randomized group design (RAK) with two factors, including: Factor I: Giving Nasa Liquid Organic Fertilizer (P), which consists of 3 levels: P0: control, P1: 2.5 ml, P2: 5 ml, and P3: 7.5 ml. Factor II: Stolon pruning (S) consists of 3 levels, namely: S0: no pruning; S1: 1 pruned stolon; and S2: 2 pruned stolons. From the results of this research, it can be concluded that the single effect of giving Nasa liquid organic fertilizer is significantly different on the number of fruit in harvest 1 and harvest 3, but is not significantly different on the number of fruit in harvest 2, plant height (cm), number of leaves (strands), and fresh weight of sample plants; the single effect of stolon pruning was not significantly different on plant height (cm), number of leaves (strands), number of fruit, and fresh weight of sample plants; and The interaction effect of giving Nasa liquid organic fertilizer and pruning stolons was not significantly different on plant height (cm), number of leaves (strands), number of fruits, and fresh weight of sample plants (g).

Abstract

Water spinach (Ipomea reptans Poir) is a type of vegetable that is very popular among Indonesians because of its delicious taste. This plant originated in India but then spread to various countries in Asia and Africa (Plucknett and Beemer, 1981). NPK fertilizer in water spinach cultivation is the most widely used compound fertilizer containing the nutrients Nitrogen, Phosphorus and Potassium. Organic fertilizers are fertilizers composed of living matter, such as weathering of plant, animal and human remains. This research will be carried out in the experimental field of the Faculty of Agriculture, Indonesian Community Development University UPMI Medan, on Jl. Waqf, Pasar 12 Marindal II, Patumbak District, Deli Serdang Regency, North Sumatra Province. Altitude 40 m above sea level. Based on the results of field observations, it directly shows the normal growth of land kangkong plants (Ipomoea reptans Poir.). Parameters observed included plant height (cm), number of leaves (strands), sample wet weight (g), overall wet weight (g), root length (cm) and root volume (mm). Single effect NPK fertilizer application at N2 level (1.5 gram/plant (300 kg/ha) has an effect on increasing plant height growth at 3 WAP) based on the 5% DMRT test. The interaction effect of NPK fertilizer and liquid organic fertilizer had no effect on plant height, number of leaves, sample wet weight, overall wet weight, root length and root volume.
