Spacing Factor

1. The interaction of physical conditions of the soil and the establishment of plant together with its subsequent growth and yield have been studied for wheat and swedes on a variable piece of land, maintained as a uniformity trial.2. Ploughing draught was taken as a criterion of the physical condition of the soil and various simple measurements on the crop were made from time to time during growth.3. The establishment of wheat showed substantial negative correlations with ploughing draught but the correlations between ploughing draught and the performance of the plant diminished as growth progressed. This was shown to be the result of the overwhelming importance of the spacing factor operating beneficially on plots where the plant was abnormally poor. The effect of this factor is traced step by step.4. Swedes differing from wheat in almost every detail of cultivation and growth, cycle showed no correlation between soil conditions and germination or between the various growth stages and physical soil conditions. The highest significant correlation was between the number of roots per plot after singling and ploughing draught and an explanation of this is given.5. There was a significant but only moderate correlation between the yields of the two crops.

Pulp Mill Sludge

Growth and yield of black cottonwood (Populustrichocarpa Torr. and Gray) and red alder (Alnusrubra Bong.) were measured at four successive 2-year coppice harvests. Three levels of amended pulp mill sludge (450, 225, and 0 t•ha−1) were applied before planting, and one-half of the plots were irrigated during the 2-year establishment period prior to the first coppice cycle. Yields of black cottonwood were generally much higher than yields of red alder; maximum ovendry yields obtained were 13.8 t•ha−1•year−1 for black cottonwood and 7.1 t•ha−1•year−1 for red alder. The species differed in their responses to treatment. Growth and yield of black cottonwood was increased by the initial sludge applications, but the reverse was true for red alder. The initial irrigation treatment had carryover effects on the yields of subsequent growth cycles for both species. For all treatments, the greatest yields were usually obtained at the first or second coppice harvest. On the average, red alder yields declined substantially between the third and fourth harvests; black cottonwood yields were generally more consistent between these two harvests. Both species sprouted after all four harvests; however, rootstock mortality generally increased with each harvest. Mortality was much higher for red alder than for black cottonwood; after four coppice harvests, mortality on red alder treatments averaged 55–79%. Average mortality on black cottonwood treatments ranged from 12 to 38%. The management implications of the results are discussed.
