This research aims to determine the effect of stolon pruning and the application of growth regulators on the growth and production of strawberry plants (Fragaria chiloensis L.). This research was located in Barus Jahe Village, Barus Jahe District, Karo Regency, North Sumatra, with an altitude of 1,367 meters above sea level from March 2023 to May 2023. This research used a split plot design (RPT) consisting of a main plot; Stolon pruning consists of 4 levels, namely P0 = pruning all stolons, P1 = pruning 1 remaining stolon, P2 = pruning 2 remaining stolons, P3 = without pruning stolons. Subplot; The concentration of growth regulators consists of 4 levels, namely; K0 = Without giving ZPT, K1 = 1 cc/L water, K2 = 3 cc/L water, K3 = 5 cc/L water. The research results show that stolon pruning has a significant effect on the number of fruits per plant. The concentration of growth regulators had no significant effect on the number of fruits per plantKeywords: Stolon, (ZPT) growth regulator, strawberries.INTISARIPenelitian ini bertujuan Untuk mengetahui bagaimana pengaruh pemangkasan stolon dan aplikasi zat pengatur tumbuh terhadap pertumbuhan dan produksi tanaman stroberi (Fragaria chiloensis L.).

Pada sistem hidroponik diperlukan sumber nutrisi untuk kelangsungan hidup tanaman. Tujuan penelitian ini adalah untuk menguji apakah pupuk NPK Mutiara 16-16-16 dapat menggantikan AB Mix dan mengetahui bagaimana pengaruh konsentrasi AB Mix dan pupuk NPK Mutiara 16-16-16 dengan perlakuan dosis yang berbeda dan dosis perlakuan mana yang terbaik untuk direkomendasikan. Faktor konsentrasi AB Mix (AB) yaitu AB1 1300 ppm, AB2 1600 ppm, AB3 1900 ppm dan Faktor konsentrasi pupuk NPK (N) yaitu N1 1500 ppm, N2 2000 ppm, N3 2500 ppm. Penelitian ini menggunakan rancangan acak lengkap dengan ulangan sebanyak 3 kali, tiap faktor konsentrasi terdapat 9 unit perlakuan sehingga diperoleh total 18 unit percobaan, dengan mengamati tinggi tanaman, diameter batang, jumlah tangkai (dahan), hari berbunga dan bobot buah segar pertanaman sampel. Hasil penelitian pada AB Mix pada konsentrasi 1600 ppm (AB2) memberikan hasil yg lebih baik pada diameter batang, jumlah tangkai (dahan), hari berbunga, bobot buah segar pertanaman sampel dan berpengaruh tidak nyata pada tinggi tanaman di setiap MSPT. Hasil penelitian NPK Mutiara 16-16-16 pada konsentrasi 1500 ppm (N1) memberikan hasil terbaik pada hari berbunga dan bobot buah segar pertanaman sampel dan berpengaruh tidak nyata pada parameter lainnya di setiap MSPT. Nutrisi AB Mix masih lebih baik dari pada pupuk NPK Mutiara 16-16-16 di setiap parameter.

Cucumber (Cucumis sativus L.) of the pumpkin tribe or Cucurbitaceae is a plant that produces edible fruit. The fruit is usually harvested when it is not fully ripe to be used as a vegetable or refreshment, depending on the type. One way to add nutrients to the soil is by applying chicken manure. According to Haryanto (2016) in Rumondang et al., (2020) also explained that the use of organic fertilizers is an action to improve the environment for plant plants that can improve the quality of land in a sustainable manner and organic fertilizers are also very beneficial for increasing agricultural production both in quality and quantity. This research was conducted on the experimental garden plot of the Faculty of Agriculture, Indonesian Community Development University UPMI Medan, on Jl. Market Village Hall 12 Marindal II, Patumbak District, Deli Serdang Regency, North Sumatra Province. At an altitude of 1000 meters above sea level. With the time of research in May-July 2023. The research was carried out in a factorial manner with the basic pattern of a randomized block design (RBD) consisting of two factors. Factor I: Dosage of chicken manure (A), namely: A0 = Control, A1 = 1 Kg/Plot, A2 = 2 Kg/Plot. Factor II: Dosage of liquid organic fertilizer orrin (O), namely: O1 = Control, O2 = 5 ml/l/plant, O3 = 10 ml/l/plant. The results showed that the single effect of giving chicken manure at level A2 (2 kg/plot) had an effect on increasing the growth of plant length, (at the age of 4 weeks), number of leaves (at the ages of 2 weeks, 3 weeks and 4 weeks), number of fruits and weight. fruit. The interaction effect of giving chicken coop and Orrin liquid organic fertilizer had no effect on plant length, number of leaves, number of fruits and fruit weight.

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).

Mustard greens (Brassica juncea. L) is one of the horticultural crop commodities from a type of vegetable that is used for its young leaves, as vegetable food and has various benefits and uses. This study used a randomized block design (RBD) with two treatment factors with 3 replications, namely: Factor I: Administration of Cow Manure (P), which consisted of 3 levels, namely: P0 = 0 kg/plot (Control), P1 = 1 kg/ plot (10 tons/ha), and P2 = 2 kg/plot (20 tons/ha), while Factor II: Administration of Urea (U) consisting of 3 levels namely: U0 = 0 g/plot (Control), U1 = 15 g/plot (150 kg/ha), and U2 = 20 g/plot (200 kg/ha). Parameters observed included plant height (2mst, 3mst, and 4mst), number of leaves (2mst, 3mst, and 4mst), root length, root volume, wet weight per sample, and wet weight per plot. The results showed that the effect of giving cow manure at 2 weeks old had an effect on increasing the number of plant leaves, but had no effect on plant height, root length, root volume, wet weight per sample and wet weight per plot. The application of Urea fertilizer had no effect on plant height, number of leaves, root length, root volume, wet weight per sample and wet weight per plot. The interaction effect of cow manure and urea fertilizer did not affect plant height, number of leaves, root length, root volume, wet weight per sample and wet weight per plot.
