66 SOILING CROPS AND THE SILO. 



the conditions were precisely the same. It was 

 necessary to plant the non-saccharine sorghums a 

 second time. 



The amount of seed required will vary with the 

 climatic and soil conditions and with the character 

 of the produce sought. The more favorable the 

 attendant conditions, the greater should be the 

 amount of seed sown when growth fine in character 

 is sought, and since the plants of some of these sor- 

 ghums produce more stalks and foliage than others, 

 it is not necessary with the former to plant so much 

 seed. Notably is this true of teosinte, and in a less 

 degree of Milo maize. When planted in rows where 

 cultivation is to be given other than harrowing, a 

 few pounds of seed will suffice for an acre. But 

 when these crops are sown broadcast, from about 

 one-half bushel to one and one-half bushels of seed 

 per acre are used. 



CitUk'ation. — \Anien the non-saccharine sor- 

 ghums are planted with any kind of drill or planter, 

 they may be harr(iwed without hazard to the plants 

 just as they begin to push up through the ground, 

 providing the harrow is light, and that when in use 

 a backward slant is given to the teeth. Later, on 

 certain soils, as those quite loose in character, such 

 as the humus soils of the prairie, s^Mne form of 

 weeder may be used in many instances, more espe- 

 cially when the plants are in rows distant from one 

 another. When thus planted, further cultivation 

 should be given with more or less frequency. It 

 should be sufficient to destroy weeds and to retain 

 moisture in the soil to the greatest extent practicable. 

 Where moisture is usually more or less wanting, the
