Effect of Potting Media on Growth, Flower Yield and Quality of Rose (Rosa hybrida L.) CV. Top Secret under Protected Condition

Tuberose (Polianthes tuberosa L.) is a perennial summer flower grown by smallholders in Kenya for export. However, its production and export volumes have declined drastically due to nematodes infestation. This study evaluated the effect of Cleome gynandra accessions on nematode management on tuberose. Experiment was conducted at the Horticulture Research Field, Egerton University, Kenya using a randomized complete block design with four replications. The treatments were: five accessions of C. gynandra namely ‘Simlaw’, ‘Egerton’, ‘Taastrup’, ‘PS’ and ‘IP8’, applied at 6 kg/m2 and compared with Brassica napus, solarization and untreated control. Data was collected on growth and yield parameters, nematode infestation and quality of tuberose. Data collected was subjected to analysis of variance at p≤0.05 and means separated using Tukey’s test. Biofumigation with Cleome gynandra accessions helped to reduce nematode population by 34%, gall numbers by 83% and galling index by be 96% when compared with the control. Use of biofumigation helped to improve plant height and leaf number of tuberose by 16% and 87%, respectively, when compared with the control. Use of biofumigation helped to improve spike length by 32%, marketable spikes by 80%, and flower yield by 90% and reduced nonmarketable spikes by 95% when compared with the control. Based on the above results, use of Cleome gynandra accessions and other biofumigants such as rape seed can be used to manage nematodes and improve growth, yield and quality of tuberose.

Keeping Quality

Supplemental lighting and nitrogen nutrition affected growth, flowering, flower yield, foliar nitrogen content, and flower keeping quality of Rosa hybrida ’Forever Yours.’ Light treatments consisted of ambient light and ambient light supplemented with high pressure sodium lamps at intensities of 105 and 158 μEm−2 sec−1 18 h/day (7.4 and 10.8 klx). Three nitrogen levels, 100, 200, and 400 ppm, were applied with each irrigation. Supplementary light of 105 μEm−2 sec−1 increased yield, stem length, fresh weight, and stem grade but caused decreased foliar N and keeping quality. Lighting at 158 μEm−2 sec−1 increased flower yield, but decreased days to flowering, stem length, fresh weight, foliar N, keeping quality, and stem grade. Nitrogen levels of 100 and 200 ppm were insufficient to maintain foliar N content at optimum levels in lighted roses, but 200 ppm N resulted in better keeping quality compared with 100. Nitrogen alone, however, had little effect on yield and quality. Increasing the nitrogen level to 400 ppm resulted in higher foliar N content in the lighted treatments but failed to have a significant effect on the yield or quality of roses.
