Abstract

Sari Devi Silalahi Npm 158210093 "The Response of Pearl NPK Fertilizer and POC Apu Apu (Pistia stratiotes L.) To Growth and Production of Cucumber Plants (Cucumis sativus L.)". This thesis is under the guidance of Dr. Ir. Syahbudin Hasibuan, M. Si as the head of discussion and Mrs. Prof. Dr. Retna Astuti. K, MS as a supervisor. This research is located in the Kebun Percobaan of the Faculty of Agriculture, University of Medan. 1 Medan Estate, Percut Seituan sub-district with a height of 22 meters above sea level flat topography and alluvial soil types. This research was conducted in May 2019 until July 2019. The purpose of this study was to determine how the response of NPK Mutiara inorganic fertilizers and Liquid Organic Fertilizers to the growth and production of cucumber (Cucumis sativus L.). This research was designed with factorial randomized block design (RBD) consisting of 2 treatment factors, namely: (1). NPK fertilizer consisting of 4 treatment levels, namely: N0 = Pearl NPK fertilizer at a dose of 300 kg / ha (30 gr / plot), N1 = Pearl NPK fertilizer at a dose of 400 kg / ha (40 gr / plot), N2 = Fertilizer NPK Mutiara at a dose of 500 kg / ha (50 gr / plot), N3 = NPK Mutiara Fertilizer at a dose of 600 kg / ha (60 gr / plot); (2). Apu-apu Liquid Organic Fertilizer (POC) which consists of 4 levels, namely A0 = 0% liquid organic fertilizer Apu-apu / 1 liter of water, A1 = 25% liquid organic fertilizer Apu-apu / 1 liter of water, A2 = 50 % liquid organic fertilizer Apu-apu / 1 liter of water, A3 = 75% liquid organic fertilizer Apu-apu / 1 liter of water. Each treatment was repeated 2 times to produce 32 experimental plots. Each experimental plot consisted of 6 plants with 3 samples. The parameters observed were: Plant Height, Stem Diamater (cm), Number of Fruits (fruits) per sample, Fruit Length (cm) Per sample, Fruit Diameter (cm) Per sample, Weight of Fruits Per Plot (gr). The results of this study were the giving of NPK Mutiara and significantly affected the height, stem diameter, number of fruits, fruit length and fruit weight per cucumber plant plot. Application of Liquid Organic Fertilizer (POC) Apu apu significantly affects the height, diameter, fruit length and fruit weight per plot. The effect of interaction between NPK and POC Apu apu fertilizer treatment significantly affected the parameters of the number of fruits and weight of the fruit per plot of cucumber plants.
