to the questions..
do a bit of homework, study how are the other farmers growing arround u ? in open, shadenet or ph?
if its open, then they cant keep growing it thru out the year.
cucumber is a short term crop, the life time is about 4 months. and is a good crop to learn the basics of pest management. also this will give you an idea about the fertigation roles. BUT only when u make the efforts Manish.
a single 4000 mtr has its own advantages and cons.
in a single setup, the infestation can spread quickly and ruin everything if you dont act on time.
then there is quantity/volume aspect, fertigation/pest management, all the year supply/price factory, your target market (few times big volume, or small quantity on daily basis) etc.
there are various combinations that can be worked upon. this is a very vast discussion, as it involves many factors, labor, transporting, and what not and a few listed earlier.
at the end of the day it all comes down to one thing, how much are you willing to do? and Manish, i am not talking about money, but efforts.
i know you are not getting your answers, but if you do everything RIGHT, you'll be happy with both the cases you have put up.
and hey! you can visit all the farms in nasik and arround, and i speak on behalf of my people
its just that i am not in nasik anymore.
