RESPON PERTUMBUHAN DAN HASIL TANAMAN STROBERI (Fragaria Sp.) TERHADAP PEMBERIAN BEBERAPA PUPUK ORGANIK CAIR

Strawberry (Fragaria Sp.) Is a type of fruit that has a high economic value and has many benefits. Strawberry production continues to increase from year to year, strawberry cultivation has been tried by several farmers in North Sumatra, West Sumatra, West Java, Malang, Bali and Sulawesi. Chemical fertilizers are often used by farmers, but this is a threat to long-term agriculture. Therefore it is necessary to have an alternative substitute for chemical fertilizers that are environmentally friendly. One of them is compost shrimp skin compost which consists of head and skin still has a fairly high nutrient content, is 25-40% protein, 45-50% calcium carbonate, 15-20% chitin. In addition, snail mas is quite potential as a source of animal protein. Conch contains other nutrients, namely calories and carbohydrates. This study aims to determine the effect of giving liquid organic fertilizer on the growth and yield of strawberry (Fragaria Sp.) Plants and to determine the most effective concentration of growth and yield of strawberry (Fragaria Sp.) Plants. This research took place in integrated agricultural land at the University of Muhammadiyah Malang for 4 months. Parameters that show significant interaction from the administration of some liquid organic fertilizers occur in the parameters of plant height of the 3rd, 6th and 7th week, the number of flowers of the 3rd, 4th and 6th week, the number of weeks fruit 4, the fruit weight of the second observation, the fruit length of the 1st, 2nd, 3rd, 5th, and 6th observations, and the 5th observation after the application
