•~ She method of calculating the amount of seed of each species applied <br />in each plot is as follows: <br />1) Z of species Y in whole miature (x) lbs/acre of whole mixture . lbs of <br />species Y/acre <br />2) lbs of species Y/acre <br />(Z germination (x) Z purity) ~ lbs of species Y (pure live seed /acre) <br />3) lbs of species Y (PLS)/acre (x) plot size (sq. ft) ~ lbs of species Y (PLS) <br />43,560 sq. ft./acre plot <br />She source of germination and parity data vas seed supplier labels on <br />the seed samples. After determi~ weight of seed required for the drill <br />i <br />plots, the total weight per plot vas divided by the number of roes per plot <br />r <br />to insane that equal amounts of seed would be planted in each row. <br />Sae 4:1 drilled plots were seeded at 30 lbs PLS/acre. All broadcast <br />~ ~ lou were seeded at 15 lbs PLS/acre. The lower seed <br />p tag rate for drilled <br />plots reflecu a higher expected ge*+~~~=tion rate because of more effec- <br />t <br />tive seed placement than with broadcasting. <br />i. <br />' 2,.4 Seeding Method And Mulch Application <br />2.4.1 Drilling Seed <br />Plots were drilled with a handroperated research plot belt seeder <br />obtained from the Agricultural Research Service. Rows were spaced approx- <br />irately 12" apart and seeds were placed at a depth of 112" to 1". The <br />machine covered the seed after placement with a small "packer wheel" <br />__ attached to the machine. Some difficulty in placing the seed properly was <br /> encountered vhea the seed spout became clogged with debris, and same <br /> disturbance of the slope was unavoidable vhea implementing this technique. <br /> <br />
