Respon Pertumbuhan dan Produksi Tanaman Sawi (Brassica juncea L) Terhadap Interval Waktu Penyiraman pada Berbagai Medi Hidroponik

Abstract

Response Research on Growth and Production of mustard (Brassica juncea L.) Against Time interval Watering In Various Media Hydroponics.Aiming to know and Production Plant Growth Response mustard (Brassica juncea L.) Against Time Interval Watering In Various Media Hydroponics. The study was conducted at the home screen experimental garden Faculty of Agriculture, University Medan Area, located in the Pool No. I Terrain Estate, District Percut Sei Tuan with altitude 12 m above sea level. This study was conducted from October 2013 until December 2013. The method used Completely Randomized Design (CRD) factorial, with 2 replications, 10 combinations, thus obtained 20 plots of plants. The first factor hydroponic growing media, namely: M1 : The roots of ferns, M2: Coconut Fiber Powder, M3: Chaff Bakr, M4: Rokwool, and M5: Saws powder, the second factor is the time interval that is: Il : 3 hours once a day, 12: 5 hours a day, starting from 08: 00-18: 00 pm. The results showed that treatment watering liquid fertilizer with different time intervals showed no significant effect on the growth of mustard plants, the treatment medium used in the hydroponic system provides a very real effect on plant height, number of leaves, leaf area, weight and production significantly affected level of leaf color. The best planting medium is M3 (husk fuel). Interaction watering intervals on various hydroponic media did not significantly affect the observed parameters, are: plant height, number of leaves, fresh weight, and the weight of production, while the significant parameters of leaf color and leaf width parameter was highly significant.
