●the advantage is that the different climate and season support specific crops and if those crops are grown it will be a benefit.
●yeild decreased as paddy demanded more in the different season
●he can irrigate the land well and put manure and natural fertilizers.

A) As mentioned paddy should be grown in kharif season because it needs more amount of water. and pulses in rabi season because pulses need less amount of water.
B) Yield decreased because paddy needs a lot of water and nutrients. so, if we grow paddy continuously then the nutrients n soil will get finished.
C) He can grow leguminous plants which have Rhizobium bacteria which can convert atmospheric nitrogen to nitrogen compounds.
OR
can add fertilizers and manures to regain its fertility.
