CROPS 



cultural crops; and the horticultural crops include fruit crops 

 (pomology), vegetable-gardening crops (vegetable-gardening 

 or olericulture) , flower- and ornament-crops (floriculture). 



422. We may group crops also as follows into more par- 

 ticular division^: forage and fodder crops; cereal grains; 

 root-crops; fiber-crops; sugar plants; oil plants; dye-stuff 



plants ; b e v e r - 

 age-p reducing 

 plants; stimu- 

 lants; aromatic 

 and medicinal 

 plants; perfum- 

 ery plants; fruit 

 crops; vegetable- 

 garden crops; 

 timber crops; 

 manuring crops. 

 Some crops fall 

 under more than 

 one division, de- 

 pending on the 

 purposes for 

 which they are 

 grown, as oats, 

 beets, peas, sor- 

 ghum, maize or Indian corn, flax: explain why. Sometimes 

 two plants are grown together purposely, as shown in Fig. 

 426, and also in Fig. 427. 



423. Many of the crops may be assembled, on the basis 

 of their botanical affinities, into the families to which they 

 belong: Grass-family crops, all cereal grains as well as the 

 meadow and pasture grasses, as wheat (Fig. 384), rye, barley, 

 oats (Fig. 382), rice, maize (Fig. 427), sorghum (Fig. 20), kafir, 

 broom-corn (Fig. 429), millets of several kinds, sugar-cane
