As shown above ihe experiment was planned to find out:â First.âThe influence of chemical fertilizers. iSepond.âThe demands of the crop and the particular elements lacking in the soil. Third.âThe necessity for using barnyard manure. GENERAL OBSERVATIONS. The information to be gathered from the field observations was as follows: Plots 1 and 4 always were ahead, while plot 6, the check plot, made very slow growth and yellowed up prematurely, not showing the natural process of ripening. Plot 4 indicated that the Burley plant required the two elements, potash and nitrogen, \rtiile phosphoric acid was least required. The manure plot gave a larger and darker green than the check plot, indicating that the soil required manure. The yields per acre, the value of the crop calculated at 16 cents per poundâ^the prevailing market priceâthe cost of the manure and fertilizer, and the net receipts per aero, are given in the following table. The cost of the fertilizer was figured according to market prices. Sulphate of potash $54 per ton, nitrate of soda $54 per ton and superphosphate $18 per ton. Farmyard manure was valued at $1 per ton. Quantity of fertilizer in iKmnHs |ier acre. Yirld of Value of crop crop Iier acre, per acre. Co»tof fertiliser per acre.
