A system to estimate the weed density between two rows of soybeans was developed. An environmentally adaptive segmentation algorithm (EASA) was used to segment the plants from the background of the image. The effect of two image data transformations on the segmentation performance of the EASA was investigated, and the RGB-IV1V2 transformation resulted in significantly higher quality segmentatio...

Abstiact-This paper analyzes difficulties arising in the use of documents produced by Reverse Engineering tools. With reference to inter-modular data Row analysis for Pascal software systems, an interactive and evolutionary tool is proposed. The tool is based on: i) the production of inter-modular data Row information by static analysis of code; ii) its representation in a Prolog program dictio...

An experiment to study the effect of inter and intra row spacing on the yielding performance of periwinkle species was conducted at Nagarjun Medicinal and Aromatic Plants Research Scheme, P. K. V., Akola (M. S.) during 1980 - 81 to 82 - 83. Three species viz., Catharanthus roseus, Catharanthus alba and Catharanthus oscillatus did not differ significantly in respect of dried foliage and root yie...

this study was conducted to evaluatethe effects of different inter- and intra-row spacing on the dry matter accumulation and partitioning coefficients in faba bean, barakat cultivar. experiment was conducted as factorial in a randomized complete block design with three replications. factors were inter-row spacing (15, 30, 45 and 60 cm) and intra-row spacing (5, 10 and 15 cm). the plant dry matt...

intercropping may be helpful manner to increase interception and utilization. the aim of this study was to compare radiation use efficiency and radiation interception in intercropping with sole cropping. an experiment was conducted at the agricultural research station, ferdowsi university of mashhad in the growing season of the year 2008. the experimental treatments were: 1- sole crop of bean 2...

In In order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (RCBD) with 4 replications in Saat-Loui agricultural station of West Azerbaijan province. In this research, the first factor (A) contained two levels 20 and 40 cm inte...

Camera-guided narrow (15 cm)-row, inter-row cultivation, with or without the Einböck rotary weeder, reduced weed growth but had lower yield than herbicide-treated dry beans. In wide rows (60 cm), camera guidance improved finger weeder performance and mechanically weeded bean yields were similar to herbicide treatment.
