GROWTH PROCESS OF ORGANIC VETIVER ROOT WITH POTATO AS INTERCROPPING PLANT

An evaluation of yield in "intercropping of maize and potato"

Abstract To find out how maize and potato can grow and develop in an intercropping system rather than each grown alone in a sole cropping system the following factorial experiment was performend in the frame-work of a randomized complete block three replications in the experimental farm of the faculty of agriculture, Zanjan University in year 2004. Different potato to maize ratios of (1:0), i...

Effects of Intercropping with Potato Onion on the Growth of Tomato and Rhizosphere Alkaline Phosphatase Genes Diversity

BACKGROUND AND AIMS In China, excessive fertilization has resulted in phosphorus (P) accumulation in most greenhouse soils. Intercropping can improve the efficiency of nutrient utilization in crop production. In this study, pot experiments were performed to investigate the effects of intercropping with potato onion (Allium cepa L. var. aggregatum G. Don) on tomato (Solanum lycopersicum L.) seed...

Measuring and Modeling of Plant Root Uptake of Organic Chemicals

The potential of xenobiotic organic compounds to be taken up by plant roots and transported to above ground tissue is an important consideration for phytoremediation projects and risk assessments alike. The transpiration stream concentration factor (TSCF), a ratio of the xylem concentration to the root-zone solution concentration, is the most commonly used parameter describing plant root uptake...

Effects of Potato Leafhoppers on Soybean Plant Growth and Yield

Various densities of adult potato leafhoppers were established on 'Essex' soybean at plant growth stage V2 in caged field plots. Cages were removed two weeks later, and plots remained uncaged for the rest of the growing season. Direct counts of nymphal leafhoppers on plants shortly after cage removal confirmed that a gradient of infestation levels was attained. In both years of the study, highe...
