leucocephala have to be totally changed in the farming system but mixed planting with indigenous or naturalized MPTs is extremely recommended, to wit B. Age of bushes at preliminary chopping affected subsequent annual leaf and stem dry matter yields but not survival fee.
Picket Planter Field
The purpose of the current research was to study population dynamics of purple nut sedge and their relations to environmental circumstances, significantly water availability. A area experiment was performed in younger robusta espresso under Leucaena shade bushes. The coffee plants were pruned by a single stem pruning system. The experiment was carried out in Kaliwining Experimental Station. Permanent sq. plots have been used within the observation of inhabitants dynamics of purple nut sedge.
Observations had been carried out with an interval of one month over two seasons in a single yr. The population dynamics of purple nut sedge under espresso plantation was carefully related to rainfall distribution. Maximum vegetative development activity occurred from the beginning to the middle of the rainy season. The highest dormancy occurred from the center to the end of the dry season. Available soil moisture was the limiting factor for vegetative progress of purple nut sedge in espresso plantation.
Square Wood Planter Box
The most of 8.eight million shoots per hectare and 12 million dormant tubers per hectare had been found on the peak of progress exercise on the finish of the rainy season. At the same time the variety of leaves was forty six million per hectare. Number of leaves decreased to 10 million per hectare on the period of the lowest growth activity through the mid dry season. leucocephala results signifies that also can carry out well though yields are less compared to those reported prior to the psyllid infestation.
It interferes the growth of more than fifty two crop species in 90 nations. In many agricultural areas, purple nut sedge is talked about as the worst weed of meals and horticultural crops. In some coffee areas (i.e. East Africa, West Africa, Latin America and Asia) purple nut sedge was reported to be the predominant weed. It affected progress price of young espresso plants and decreased coffee yield.
