FORAGE CROPS, MEADOWS AND PASTURES 



F. plicatuhim, which is pecuHar to sandy soils. There are also the following 

 marsh species: P. Larranagai Arech., P. rmiltiflorum Doell., P. fascicidatum 

 Willd., P. femiginemn Trin., which may serve for pasturage during times 

 of drought ; finally, P. scoparium Fliigge and P. barbatum Nees, thrive 

 on the patches of moist soil which occur on stony surfaces. 



Paspalum grasses are generally sown in autumn or spring with other for- 

 age plants, preferably with clover or lucerne in the proportion of 5 to 7 lbs per 

 acre, after giving a good dressing to the soil. It is best to feed them green 

 to the livestock before complete flowering. For this purpose they are cut 

 at that time, or fed to cattle off the land at an early moment, after which 

 a second crop is obtained. Paspalum may be sown alone, in order to 

 improve existing grasslands, or for seed production. In the latter case 

 sowing is at the rate of 26 ^/^ to 35 ^(^ lbs per acre, which yields a crop 

 of 357 to 535 lbs of seed. The seeds are also cropped from plants growing 

 wild on stubble. 



The anaWtic data contained in the appended Table are interesting, 

 as they indicate the nutritive value of some of the principal species of Pas- 

 palum.
