My project is testing the effects of chemical pesticides on pea plants and measuring various things, such as hight of tallest stock of each plant, rate of growth in days, and measuring the weight of each plant
Here are some questions that I need answered (plus it wouldn't hurt to leave some information on pea plants or chemical pesticides
1. When did people start to use chem. pesticides a lot (years) and where. (majority)
2. When did they come out with the idea of chem. pesticides.
3. When are pea plants grown. (time of year)
4. What conditions are pea plants grown in.
I would appreciate if these questions were answered and maybe more information.
