Effect of various intra-row skips, plant populations, and irrigation levels on development and yield in cotton

摘要

Cotton (Gossypium hirsutum) production and lint quality were evaluated using two varieties (PM2200RR and PM2326RR) in three skip patterns (Fig. 1) at a constant population of 52,272 plants/acre (average of 4 plants/foot) at Halfway, TX and Lubbock, TX, in 1998. The same study was expanded in 1999 to include three plant populations (52,272, 39,204, and 26,126 plants/acre) and two irrigation regimes (50 percent and 100 percent ET replacement). No differences where noted in yield due to plant population, skip pattern, or irrigation level in either year. Differences were observed for the lint strength and micronaire in 1998, but no cause and effect relationship could be identified.
