Soybean tolerance to defoliation at the beginning of pod formation as affected by plant density
نویسندگان
چکیده
Soybean tolerance to defoliation may be affected by population density, as the plant interferes with crop leaf area index . This study aimed evaluate effect of at beginning pod formation on agronomic performance soybean different densities. The experiment was conducted under field conditions in Campos Novos, SC, Brazil, during 2016/2017 and 2017/2018 growing season. experimental design a randomized block split-plot arrangement. main plot consisted three densities (100,000, 300,000, 500,000 plants ha−1), whereas subplots cultivar NA 5909 RG submitted five levels (0, 16.6, 33.3, 50, 66.6%). Grain yield ranged from 4,219 5,356 kg ha−1 season 3,732 5,186 Plant density did not interfere grain response performed formation. 16.6% increase 7.5 5.6% relative control seasons, respectively. tolerate up 33.3% R3 no significant decrease yield, regardless density.

Salinity Tolerance of Kentucky Bluegrass as Affected by Salicylic Acid
Salinity is one of the greatest environmental challenges facing plant growth and development in the 21st century. Salicylic acid (SA) is a phenolic compound and signal molecule involved in the regulation of plants responses to biotic and abiotic stresses. This greenhouse experiment was conducted to determine effects of SA application on Kentucky bluegrass (Poa pratensis L.) responses to salinit...
