Seven different fertilizer mixtures, namely cow dung, coir dust, mush room medium waste, saw dust, compost, decaying leaves and field soil with standard dose of NPK （control） were used for this experiment. The variety used was PM 25. Soil microbial activity was measured using CO2 evolution method. The experiment was carried out as a complete randomized block design with five replicates at the rate of eight plants per replicate. Average number of leaves on 25-day and 45-day old plants, shoot-length, root-length, number of pods per plant, wet weight of pod per plant, dry weight of pod per plant, plant wet weight, plant dry weight and seed dry weight per pod were measured. All management practices were conducted according to recommendations of the Department of Agriculture from seed germination to harvesting. Data were analyzed using SAS program （9.1.3）. Highest number of pods/plant （100, 124, 102, 106） and dry-seed-weight in g/plant （12, 14.8, 12, 12） were recorded in those grown in cow dung, compost, decaying leaves and inorganic mixture （control） whereas the lowest pod production （8.7 pods/plant） and seed dry weight （1.0 g/plant） was recorded in saw dust. Instead of inorganic fertilizer there is possibility to use organic potting mixtures like compost and decaying leaves which gave a significant difference in crop productivity as compared to other treatments. Significantly highest mean microbial activity was observed in potting media filled with coir dust.展开更多

The aim of this paper was to test a peat/compost based substrate and a guano ＋ mycorrhizal inoculum fertilizer mixture, in order to obtain a sustainable quality yield of geranium plants. Geranium cuttings （Pelargonium zonale cv. real polaris and Pelargonium grandiflorum cv. lotus） were grown for two months in a glasshouse. Peat, in the growing substrate, was replaced with high quality compost （20% and 40% as reduction percentages）. The fertilizer mixture was made up of guano （3 g/L） and mycorrhizal inoculum （7.5 L/m^3）. Plants of Pelargonium cv. Real polaris, grown on a substrate made up of peat and 20% of high quality compost, presented the better trade features, so to satisfy the ＂sustainable floriculture＂ need.展开更多
