Weed density classification in rice crop using computer vision

Computers and Electronics in Agriculture, 2020
Abstract Weeds are normally sprayed uniformly across field irrespective of their density in the field. Automatic methods can be developed that help us to locate and spray weed according to its density. Automatic weed detection is necessary for precision spraying that can improve rice yield and reduce production cost.

Modelling the effect of duration of weed competition, weed density and weed competitiveness on seeded, irrigated onion

Weed Research, 1996
SummaryWeed removal experiments were conducted in growers' fields in northern Colorado to assess the effect of duration of competition, weed density, weed competitiveness and crop density on irrigated seeded onion (Allium cepa L.). Duration of competition, expressed in thermal time units (TTUs) with a base of 7.2^C, explained 65% of the variation in ...
