Abstract

Sidimpuan snake fruit (Salacca sumatrana Becc.) plants have several varieties, one of which has a distinctive feature in the taste and colour of the fruit flesh. The results of the study from the three locations in Padangsidimpuan City obtained the morphological characteristics of sweet snake fruit (less) having a round oval to long triangular shape with brown to yellowish-brown fruit skin colour. The results of the dendrogram of the sidimpuan snake fruit (Salacca sumatrana Becc) kinship relationship based on the morphological characters of five types of salak, namely sweet snake fruit(less), sweet snake fruit (moderate), sweet snake fruit, white snake fruit, and red snake fruit, obtained 3 clusters from each location. Lubuk Raya Village, the Sidimpuan snake fruit kinship relationship based on five types of snake fruit, has a similarity level of 84 %. Batu Layan Village, the Sidimpuan snake fruit kinship relationship based on five types of snake fruit, has a similarity level of 92 %, and Palopat Maria Village, the Sidimpuan snake fruit kinship relationship based on five types of snake fruit, has a similarity level of 96 %. The results of the identification of morphological characters of snake fruit from three research locations based on the morphological characters of five types of snake fruit show genetic similarities, namely in the shape of the stem, leaf shape, upper leaf colour, lower leaf colour, leaf sheath colour, thorn colour, flower colour, fruit shape, and fruit skin colour

Abstract

Shallots (Allium ascalonicum L.) are a horticultural commodity with high sales value and a complete nutritional profile.. This study was conducted in Padang Lawas Regency from February to April 2025. The research method is an experimental study, using a factorial randomized block design. The first factor is Liquid Smoke consisting of 3 levels, namely: A0 = Without giving liquid smoke, A1 = Liquid smoke 70 ml / L, A2 = Liquid smoke 90 ml / L. Factor II is the provision of rice husk biochar with soil consisting of 3 levels, namely: B0 = Without giving rice husk biochar B1 = rice husk biochar 210 gr / polybag, B2 = rice husk biochar 300 gr / polybag, The parameters observed are Plant Height (cm), Number of Leaves (strands), Number of Bulbs Per Clump (bulbs), Wet Weight of Bulbs Per Clump (grams), Dry Weight of Bulbs Per Clump (grams) and Bulb Weight Loss (%). The data obtained were analyzed using statistical analysis of variance followed by the Least Significant Difference Test (LSD). The results of the study showed that the application of liquid smoke significantly affected growth (plant height) in the early vegetative phase (14 days after planting) and significantly affected shallot production (number of bulbs per clump). The use of liquid smoke at a treatment level of 70 ml/L and biochar at a treatment level of 300 g/polybag produced the best results for shallot cultivation.

Abstract

Lettuce (Lactuca sativa L.) is a vegetable with numerous benefits and high economic value. The study was conducted in Neighborhood VI, Pasar Sibuhuan Village, Barumun District, Padang Lawas Regency, North Sumatra, in March 2025. The research method is an experimental study, using a factorial randomized block design. The first factor is liquid organic fertilizer of moringa leaves with 3 levels, namely P0 = Without giving liquid organic fertilizer of moringa leaves, P1 = liquid organic fertilizer of moringa leaves (120 ml/L), P2 = liquid organic fertilizer of moringa leaves (220 ml/L). The second factor is Trichoderma with 3 levels, namely T0 = Without Trichoderma, T1 = Trichoderma (20 gr/polybag), P2 = Trichoderma (30 gr/polybag). The parameters observed are plant height (cm), number of leaves (strands), leaf length (cm), leaf width (cm) and fresh weight (grams). The results of the study showed that the administration of liquid organic fertilizer from Moringa leaves significantly affected the initial vegetative growth (height, leaf length) and production of lettuce plants (P1 dose of 120 ml/L), while the Trichoderma treatment also significantly affected the growth and production of lettuce plants. The dose of 30 g/polybag (T2) had a positive effect, especially in increasing the number and width of leaves, as well as supporting the formation of plant biomass. The combination of moringa leaf POC and Trichoderma yielded the best results for lettuce growth and yield. The P1T2 treatment combination (120 ml/L and 30 g/polybag) was shown to produce the highest plant height and fresh weight.

Abstract

This study aimed to examine the effects of cow manure application and bulb tip cutting on the growth and yield of shallots (Allium ascalonicum L.). The observed parameters included plant height, number of leaves, number of bulbs per clump, fresh weight, dry weight, bulb diameter, and weight loss after storage. The results showed that the application of cow manure had a significant effect on early plant growth, particularly on plant height at 14 days after planting (p < 0.05), and also affected the number of leaves and bulbs per clump at manure doses of 50 g/polybag (A1), 100 g/polybag (A2), and 150 g/polybag (A3) compared to the control (A0). The bulb tip cutting treatment significantly influenced growth at ¼ (B1) and ⅓ (B2) cutting levels compared to no cutting, especially in the number of leaves and shoot emergence rate. The interaction between cow manure and bulb tip cutting also showed a significant effect. The best combination was obtained in A2B1 (100 g/polybag of cow manure + ¼ bulb tip cutting), which produced an average plant height of 39.17 cm, an average of 32.33 leaves at 35 days after planting, an average fresh bulb weight per clump of 159.67 g, and an average dry bulb weight per clump of 107.16 g. Therefore, this combination treatment can be recommended as a simple cultivation technique to enhance shallot productivity in low-fertility soils
