SWINE RAISING IN HAWAII. 33 
LEGUMES. 
Leguminous crops, including alfalfa, cowpeas, peanuts, velvet 
beans, soy beans, and pigeon peas are rich in protein and can be 
used to a large extent to replace imported grains and millstuffs. 
Alfalfa is one of the best perennial forage crops for swine and can 
easily be grown, if conditions are favorable. It should be planted in 
January. February. March, and November, and 8 to 12 pounds of 
the seed should be sown per acre in drills 12 to 18 inches apart. 
Cowpeas is one of the best all round annual forage crops for swine. 
The seed should be sown at the rate of 20 to 40 pounds per acre 
in rows 30 to 45 inches apart. The best time for planting is in Feb- 
ruary. May. October, and November. Cowpeas may produce one 
ratoon crop. 
Peanuts, if fed in combination with corn, are especially fine for 
fattening hogs. Two bushels of nuts in pods, or about 20 pounds 
of shelled nuts, per acre should be planted in rows 30 to 45 inches 
apart. They may be planted in February. May. October, and No- 
vember. Volunteer crops may be produced from seed that is left in 
the ground. If fed alone peanuts tend to produce a soft pork. 
Velvet beans make an excellent hog forage if they are fed when 
the seeds begin to ripen and are supplemented with grain. About 50 
pounds per acre should be sown in rows from 30 to 60 inches apart. 
They can be planted in February. May. October, and November and 
may produce one ratoon crop. 
Soy beans seed heavily and make very nourishing forage for hogs. 
From 25 to 50 pounds of seed per acre should be sown in rows 30 to 
45 inches apart. They can be planted in February. May, October, 
and November. 
The pigeon pea crop, which is practically a new forage crop for 
swine in Hawaii, should, before feeding, be ground into fine meal for 
best results. From 10 to 20 pounds of seed per acre should be sown 
in rows 45 and 60 inches apart. The crop is a perennial and can be 
planted in February. May, October, and November. 
ROOT AXD TUBER CROPS. 
Eoot and tuber crops are relatively low in protein content and high 
in carbohydrates. Among the best for swine feeding are sweet po- 
tatoes, cassava, edible canna. and Jerusalem artichokes. 
The sweet potato is one of the cheapest crops to grow for swine. 
It should be supplemented with leguminous forage crops. The cut- 
tings should be planted in lots of 10.000 per acre in rows 36 to 4^ 
inches apart. The best time to plant is during February. May. 
October, and November. Tubers that are left in the ground are 
likely to produce volunteer crops. 
Cassava is a rich feed in carbohydrate. It should be fed in com- 
bination with feeds that are rich in protein. From 3,500 to 4,500 
cuttings may be planted per acre in rows 30 to 60 inches apart. The 
time of planting is February. May. October, and November. This 
crop does not ratoon. 
Edible canna should be cooked before it is fed to swine. From 
3.500 to 4,500 bulbs should be planted per acre in rows 30 to 60 inches 
apart. Edible canna may be planted in February. May, October, and 
November.
