These statements are not mere opinions, but determined facts whose accuracy stands unquestioned. On another field at Rothamsted, England, the average yield of barley for the same sixty years was 43 bushels an acre where nitrogen, phosphorus and calcium were regularly applied, 42.6 where all five elements including potassium and magnesium were added, but only 14.3 on unfertilized land.
It is also a good fact that as an average of sixty years the yield of barley was increased by 21.6 bushels an acre by nitrogen; that nitrogen increased the yield of hay on permanent meadow land at Rothamsted by 1-1/2 tons an acre as a fifty-year average; and that nitrogen increased the average yield of potatoes by 88 bushels as an average of twenty-six years; while the average of the unfertilized land was only 51 bushels an acre, these increases in barley, bay, and potatoes being obtained over and above the yields where minerals alone were used.
But it is reached by only a very few pollen-tubes, and is therefore always incompletely fertilized. It does not fall off after the fading away of the flower, as unfertilized ovaries usually do; neither does it grow out, nor assume the upright position of normal capsules. It is checked in its development, and at the time of ripening it is nearly of the same length as in the beginning.
"The avocado is excellent," I said. "There are numerous avocado groves near my center in California." Gandhi's face lit with interest. "I wonder if they would grow in Wardha? The SATYAGRAHIS would appreciate a new food." "Not unfertilized eggs." The Mahatma laughed reminiscently. "For years I would not countenance their use; even now I personally do not eat them.
You could go on further to illustrate the facts of reproduction by bees and ants, so familiar to children, where the drone or male bee, or the male ant, in just the same way as in the plant, fertilizes the eggs of the queen bee or ant by bringing the spermatozoa into contact with the unfertilized egg in the insect's body, when the eggs thus fertilized are laid and carefully nurtured by the working bee or ant.
Each sperm is an individual entity and several thousands of them are produced and in readiness for use, at each meeting of the male and female generative organs; and if any one of the countless number comes in contact with the unfertilized ovum in the womb, conception is liable to result.
One might also bring forward the case of the Three-pronged Osmia, who distributes the two sexes without any order in the hollow of her reed. What singular whim is the mother obeying when, without decisive motive, she opens her seminal phial at haphazard to anoint a female egg, or else keeps it closed, also at haphazard, to allow a male egg to pass unfertilized?
Wheat increased forty-two per cent. Hay increased seventy-seven per cent. "As a general average of the four crops for the twenty-four years, the produce where mineral plant food is applied, was forty-nine per cent. above the yields of the unfertilized land, although the same rotation of crops was practiced in both cases."
Wheat grown once in four years has been the only crop worth raising on the unfertilized land during the last twenty years, and even the wheat crop has distinctly decreased in yield; although where mineral plant food was applied the yield has increased from thirty bushels, in 18851 to thirty-eight bushels as an average of the last twenty years.
"If we compare the average yield of turnips, barley, clover, and wheat of the last twenty years with the yield of turnips in 1848, barley in 1849, clover in 1850 and wheat in 1851 we find that on the unfertilized land in this rotation of crops in fifty years the yield of turnips has decreased from ten tons to one-half ton, and the yield of barley has decreased from forty-six to fourteen bushels, the yield of clover has decreased from two and eight-tenths tons per acre to less than one-half ton, while the yield of wheat has decreased only from thirty bushels to twenty-four bushels.
