Local Resources Utilization For Planting Media Materials In Limapuluh Kota As A Replacement For Rockwool On Pakchoy ( Brassica rapa L ) Growth And Production

The development of technology in agriculture is currently speedy, with innovations that can increase the production and quality agricultural products. Supporting hydroponic cultivation system's success by applying porous well-aerated media availability sufficient nutrients for plant growth production. Rockwool difficult to obtain 50 Kota Regency. It needs utilize local potential as a planting medium alternative, such using bricks husk charcoal. research was conducted completely randomized design three replications. treatments tested composition growing Drip flow technique (DFT) system included: Rockwool, Husk Charcoal (50%) + Bricks (50%), (25%) (75%). Based on results discussion analysis previously described, conclusions obtained from has been carried out are follows: Treatment use various types observation Pakcoy plants gives significantly different variables leaf length, width, number leaves total wet weight.
