Effects of substrates on bean growing in the greenhouse

International Symposium on the Horizons of Using Organic Matter and Substrates in Horticulture -- APR 06-09, 2002 -- CAIRO, EGYPTWOS: 000185090200004This research was conducted in an unheated PE greenhouse at the Faculty of Agriculture, Ege University during the autumn and spring seasons of 2001 and 2002 in order to determine the effects of locally available substrates on bean plants grown in open system. In the experiment, the tested substrates were (1) perlite, (2) perlite+peat (3:1, v/v), (3) tuff and (4) tuff+peat (3:1, v/v). The substrates were filled into horizontal pots as 24 liters. The seeds of cv. Altin Belik were sown as three groups per pot on 3 September 2001 and 27 February 2002 for autumn and spring season production, respectively. Water and nutrient requirements of the plants were supplied with complete nutrient solution. Plants in different substrates were fed from the same tank, but drained water was collected into separate tanks from each plot and their volumes were recorded. The amount of drained water was kept at 20 % of the applied amount. In the experiment, yield, some fruit quality parameters (average pod weight, pod width, length and thickness, pod color and crude fibre content) and water consumption were measured. There were no significant differences among the substrates in respect to total yield in autumn and spring season production.ISH

Organic tomato production in the greenhouse

7th International Symposium on Protected Cultivation in Mild Winter Climates - Production, Pest Management and Global Competition -- MAR 23-27, 2004 -- Kissimmee, FLWOS: 000226378900094This study was conducted to introduce organic greenhouse tomato production by comparing different organic fertilizers during the autumn and spring seasons of 2001 and 2002. The tested fertilizers were (1) poultry manure, 30 tons ha(-1), (2) farmyard manure, 30 tons ha(-1), (3) farmyard manure, 50 tons ha(-1), and (4) commercial (biofarm) organic manure, 2.5 tons ha(-1). Seedlings of tomato cultivars Beril 7314 and Celeya were planted on 31 August 2001 and 13 March 2002, in the autumn and spring season production, respectively. The highest total yield (7.48 kg m(-2)) was obtained from commercial (biofarm) organic manure, 2.5 tons ha(-1) in autumn, whereas in spring season total yields did not differ statistically significant according to the organic fertilizers and the average total yield was between 9.37 and 10.67 kg m(-2). During the harvest period, fruit samples were taken twice and analysed for their quality (total dry matter content, total soluble solids, titratable acidity, pH and vitamin C). Beside the yield and fruit quality parameters, soil properties and leaf nutrients of each treatment are presented
