Pesticides associated with the turfgrass industry have been detected in storm runoff and surface waters of urban watersheds, invoking concern of their potential environmental effects and a desire to reduce their transport to nontarget locations. Quantities of chlorpyrifos, dicamba, dimethylamine salt of 2,4-dichlorophenoxyacetic acid (2,4-D), flutolanil, and mecoprop-p (MCPP) transported in run...

The Asiatic hybrid lily, a bulbous ornamental plant, has a special position in the horticulture as cut flower. To overcome some problems in nutrition of bulb flowers, the use of hydroponic system and nutrient solution is important in the cultivation of these flowers. The Asiatic Hybrid Lilium bulbs “Tresor” cultivar, used for the current research were planted under 3 different calcium levels in...

Manure not only supplies many nutrients for crop production, but it is also a valuable source for increasing soil organic matter content and improving soil structure. To increase organic manure content as well as improve the wheat production adding plant residues and livestock to soil is necessary. The experiment was conducted in Shavoor Research Station to determine seed yield and soil physica...

Agricultural expansion is one of the prime driving forces of global land cover change. Despite the increasing attention to the factors that cause it, the patterns and processes associated with indigenous cultivation systems are not well understood. This study analyzes agricultural change associated with subsistence-based indigenous production systems in the lower Pastaza River Basin in the Ecua...

The predatory bug Orius sauteri is an indigenous natural enemy of thrips and whiteflies in Asian countries. To put these bugs to practical use in pest management, methods to attract and retain the bugs in agricultural fields are needed. We previously showed that violet light (405 nm) attracts O. sauteri selectively. Many thrips and whiteflies are attracted to UV or green light. In this study, w...

The objectives of this study were to verify changes in potato tuber number and weight under climatic variations a cool region Japan. We investigated growth over 3-year period from 2019, establishing plots with different planting times maturity types. In 2020, early encountered dryness during the formation after sprouting, which significantly reduced numbers. Temperature was identified as main f...

in order to study the effect of flaming on seed viability of sinapis arvensis l., changes in microorganisms population and physicochemical characteristics of soil after canola (brassica napus l.) harvesting, an experiment was carried out based on randomized complete block design with four replications and eight treatments at karaj research center, iran, during 2005- 2006. after harvesting canol...
