Respon Pemberian Pupuk Kandang Kambing dan POC Limbah Tahu yang Dicampur dengan Cangkang Telur Terhadap Pertumbuhan dan Produksi Tanaman Semangka (Citrullus vulgaris Schard)

Abstract

The Response of The Giving of Goat Manure and POC of Waste Tofu that Mixed With Eggshell toward The Growth and The Production of Watermelon (Citrullus vulgaris Schard). Essay. In the guidance of Erwin Pane as the chairman of the mentor and Ellen L.Panggabean as the member of the mentor. The research was done in the Experimental Garden of Faculty of Agriculture, Medan Area University, Jalan PBSI No. 1 Medan Estate, Sub district of Percut Sei Tuan with the height was 22 meter above the sea level, the topography was flat, and the type of soil was alluvial, was held since October to November 2018. This research was done by using the Factorial randomized block design (RBD), with 2 factors: 1) The factor of the dose of the goat manure (notated by K) consisting of 5 levels of treatment, that are : K0 = without the goat manure; K1 = 3 kg/ plot; K2 = 6 kg/ plot; K3 = 9 kg/ plot; K4 = 12 kg/ plot; 2) The factor of the combination of POC (liqud organic fertilizer) of the waste tofu and the eggshell (notated by L), consisting of 4 levels of treatment, : L0 = with the NPK fertilizer; L1 = 200 ml of POC (liqud organic fertilize) of waste tofu 100 g eggshell per plot; L2 = 400 ml POC of waste tofu 200 g eggshell per plot; L3 = 600 ml POC (liquid organic fertilizer ) of waste tofu 300 g eggshell per plot, each treatment repeated twice. The observed parameter in this research was the length of the plant, the flowering age, the number of fruit per sample, the number of fruit per plot, the coil of fruit per sample, the weight of fruit per sample, and the weight of fruit per plot. The results from this research were 1) the giving of the goat manure had a real effect towards the length of the plant, the coil of the fruit per sample, the weight of the fruit per sample and the weight of the fruit per plot, but had no real effect towards the flowering age, the number of fruit per sample and the number of fruit per plot. The giving of 12 kg/ plot of the goat manure was the treatment that could increase the growth and the production of watermelon; 2) The giving of POC (liqud organic fertilizer) of the waste tofu eggshell had a real effect towards the length of the plant, the coil of the fruit per sample, the weight of the fruit per sample and the weight of the fruit per plot, but had no real effect towards the flowering age, the number of the fruit per sample and the number of fruit per plot. And POC (liquid organic fertilizer ) of the waste tofu with dose 600 ml eggshell 300 g/ plot was the treatment that could increase the growth and the production of watermelon; and 3) The combination of the both treatment factor had no real factor towards the growth and the production of the watermelon.
