Summary

Since the profitability of the geranium crop depends to a great extent on the total yield of oil per acre, methods of increasing this yield are of prime importance. Two trials were laid down to determine the responses to nitrogen, phosphate and cutting at various times during the year. Phosphate increased total weight of green material, nitrogen had little effect, and neither significantly affected the yield of oil per ton cut. Time of cutting influenced both oil and green material yields. Climatic factors producing higher yields of green material had the opposite effect on yields of oil per ton of material cut, and vice versa. Fertilizers had no discernable effect on oil quality, but there was an appreciable difference between oil produced after wet and dry periods.
