Hydroponic Vegetables Production : A COMPARATIVE STUDY OF THE TWO NUTRIENTS SOLUTION RECIPES FOR GROWING VARIOUS VEGETABLES IN A NON-CIRCULATING HYDROPONIC

A comparative study of the two nutrients solution recipes in different strengths(Full and Half) for growing various vegetables in a non-circulating hydroponics system" was conducted at NWFP Agricultural University Peshawar, Pakistan, during the spring and fall seasons of 2006.The objectives of the study were to promote the activity of clean gardening/ urban home gardening for the landless city dwellers through the adoption of non-circulating hydroponics technology for growing fresh vegetables in their cemented court yards, verandas or the cemented rooftops. The results indicated that Cooper's 1988 solution recipe remained better than the Imai's 1987 solution recipe for almost all crops(Cucumber,Tomato,lettuce and spinach) because of an ease in keeping the pH and EC of the solution with in the optimum range when prepared with the ordinary tap water.
