The Effect of Chicken Manure and NOT Lau Kawar on the Growth and Yield of Cucumber (Cucumis sativus L.) Zatavy F1 Variety

Cucumber is one of the commodities that has very good prospects for development, because cucumbers are widely needed by the community and provide many benefits for humans and also because of high market demand. However, the development of cucumber plants has obstacles, namely many dry lands that have low soil fertility levels, so input in the form of fertilization is needed. The purpose of the study was to analyze the effect of chicken manure and organic plant nutrients (NOT) Lau Kawar and their interactions on the growth and yield of cucumber plants of the Zatavy F1 variety; and to obtain the dose of chicken manure and the concentration of NOT Lau Kawar on the growth and yield of cucumber plants of the Zatavy F1 variety. The study was conducted from January 2024 to March 2024 starting from the preparation of planting media, fertilization, planting, harvesting, and data collection. The location of the study was in the P4S Lau Kawar land, Soekarno Hatta Road Km 36, Sungai Merdeka Village, West Samboja District, East Kalimantan. The study used a 4x4 factorial experiment in a Completely Randomized Design (CRD). The first factor, the dose of chicken manure (A) consisted of 4 levels, namely: a0 = without giving chicken manure; a1 = 83.33 g polybag-1 equivalent to 10 tons ha-1; a2 = 124.99 g polybag-1 15 tons ha-1; and a3 = 166.67 g polybag-1 equivalent to 20 tons ha-1. The second factor, the concentration of NOT fertilizer (N) consisted of 4 levels, namely: n0 = without NOT fertilizer; n1 = 18 ml l-1 water; n2 = 28 ml l-1 water; and n3 = 38 ml l-1 water. From the two treatments, 16 treatment combinations were obtained, each treatment combination was repeated 4 times so that 64 polybags were obtained. The results showed that the provision of chicken manure had a significant to very significant effect on plant length and number of leaves at 20 and 30 days after planting, the number of fruits per plant, fruit length, and fruit weight per plant. The best growth and yield of cucumber plants were produced in the treatment of 124.99 g polybag-1 (a2); The provision of NOT Lau Kawar had a significant to very significant effect on plant length at the age of 20 and 30 days after planting, the number of fruits per plant and fruit weight per plant. The best growth and yield of cucumber plants were produced in the treatment of 28 ml l-1 water (n2); and there was no interaction between the treatment of chicken manure and the treatment of NOT Lau Kawar on the growth and yield of cucumber plants, except for the parameter of plant length at 20 and 30 days after planting.
