Does Minimum tillage and conventional tillage have any effect on growth and development of trees ( Tectona grandis and Aegle marmelos). If so please explain how do they create the difference.
I don't think that minimum tillage (conservation tillage) and conventional tillage have any effect on growth and development of Tectona grandis and Aegle marmelos which are deep rooted tree species.
When looking into the initial establishment phase of seedling, tillage does help in better survival of the seedling. In later stage they a significant role in reducing the weed growth.
I think tillage practices may improve growth and development of tree species. This effect will be high in seedling and sapling stage as compared to tree stage.
Yes it has lot of impact on trees as Tillage improves soil moisture in the profile and tree growth will be good. I have seen that tillage has more effect during drought years compared to normal and above normal rainfall situations and hence during drought years in SAT water is essential. Different tillage practices like conventional/ conservation tillage effects are different at different places. I have already published two papers in soil and tillage Journal about the conventional tillage suitable for greater moisture conservation.
Sure as tillage practices are helpful in root pruning and new roots are more effective in uptake of nutrients, in addition to get more appropriate underground conditions due to loosening of soil.
if I understand your question, it's depending on several variables such as type soil, type of machinery, and species-specific resource requirements, etc. Anyway, there's a bunch of papers discussing that. Here, I send you one could be working for your goal, look the reference to get more information about your concern. Good luck! http://www.nrs.fs.fed.us/pubs/jrnl/2012/nrs_2012_lof_001.pdf
