实验对象。测试谷物品种的目的是找出哪种谷物能给农民带来最好的回报。这可能取决于质量，但一般来说，产量的增加才是有利可图的，而且由于产量每年、每个农场的变化很大，因此很难获得确凿的证据。然而，可以肯定的是，由于用改良品种取代了本地谷物，产量得到了相当大的提高；作为一个例子，我可以引用爱尔兰的例子，那里引进了大麦品种，实验表明这些品种的平均产量比它们所取代的大麦高出 150/0 至 200/0。这可能意味着该国每年的收益不少于 25 万日元。作为。从开始到现在的实验成本不可能达到4万英镑，这笔钱花得很值。
OBJECT OF EXPERIMENTS. THE object of testing varieties of cereals is to find out which will pay the farmer best. This may depend on quality, but in general it is an increase of yield which is profitable, and since yield is very variable from year to year and from farm to farm it is a difficult matter upon which to obtain conclusive evidence. Yet it is certain that very considerable improvements in yield have been made as the result of replacing the native cereals by imnproved varieties; as an example of this I may cite the case of Ireland, where varieties of barley have been introduced which were shown by experiment to have an average yield of 150/0 to 200/0 above those which they replaced. This represents, probably, a gain to the country of not less than Y?,250,000 per year. As. the cost of experiments from the commencement to the present time cannot have reached ?40,000 the money has been well spent.
