Irrigation and plant density effects on head rot and yield of broccoli

Creator:: Ludy, Robin L.
Abstract:: Effects of amount of applied water and frequency of irrigation on head rot and yield of three broccoli cultivars were evaluated in 1987 and 1988. Two irrigation frequencies were established with a line-source sprinkler system for 5.5 weeks during heading. The low-frequency experiment was watered once per week and the...

Effect of a broccoli green manure, soil solarization, and isolates of Verticillium dahliae on Verticillium wilt of agronomic and nursery crops

Creator:: Berlanger, Ingrid E.
Abstract:: Green manures, soil solarization, and long rotations with crops not susceptible to Verticillium wilt are among the disease management tactics currently under investigation as alternatives to chemical fumigation of soil. The effect of a broccoli green manure on soil microsclerotial populations of three isolates of Verticillium dahliae and on Verticillium...

Stability of soil structure for water movement in an aridisol

Creator:: Ali, Safdar
Abstract:: Lack of stability of soil aggregates for water movement is a major problem in arid soils due to low organic matter and higher sodium contents. Soil amendments for improving stability of structure and increasing infiltration of water are essential to solve water management problems in these areas. Different rates of...
