Growth seasonal

It is the determination of volatile organic compounds produced from natural products that requires separation techniques that allow isolation of stereoisomers. The most commonly determined groups are the terpene and sesquiterpene species present in essential oils, which are used as key indicators of biological factors such as the growth season, geographic location, climate, etc. These species are also released directly into the atmosphere by very many plants and trees, and make a substantial contribution to global biogeochemical cycles. 

HYVs of cash crops obtained popularity due to their early maturity in one growth season as compared to 2-3 years maturity cycle of kuth and manu and early economic returns in one growth season (Kuniyal et al., 2004). Farmers were less interested towards kuth cultivation due to lengthy cultivation cycle, small land holdings, early profits with HYVs of cash crops,... 

Use Insecticide and ovicide, but must be used in the dormant growth season or as a salt to reduce toxicity. Herbicide for preemergence treatment, increases yield of corn 5-10%. 

Autumn Leaves A color change can indicate a chemical reaction. When leaves change colors in autumn, the reaction may not be what you expect. The bright yellow and orange are always in the leaves, but masked by green chlorophyll. When the growth season ends, more chlorophyll is broken down than produced. The orange and yellow colors become visible.

Some of the species involved in phytoplanktonic blooms are toxic and can pose a danger to humans. Cyanobacterial blooms (e.g. Anabaena) resulting from eutrophication in lakes and other still waters in late summer can release toxins into the water. Although cyanobacteria occur naturally in the succession of phytoplanktonic species during a typical growth season... 

Zinc deficiency in plants varies from year to year, though wet, cool, cloudy weather during the early growth season increases the deficiency (Vitosh et al. 1994).

Residual tests were carried out in maize fields at Agricultural Science Experimental Station of Jilin Agricultural University in 2005 and Hailun city in Heilongjiang in 2006. The residual tests were performed by College of Resource and Environmental Science, Jilin Agricultural University. During the growth season, maize was sprayed one time with 30 % clacyfos EC at 900 g ai/ha.
