Zbnf paddy nursery turning yellow

Hi frnds
Paddy nursery turning yellow I have treated with bijamrut before showing and applied jevamrut after 10 days but it turning yellodo what to do[glow=red,2,300][/glow]

Do not keep water standing during day time .
Keep water stagnant for a couple of hours and release it immediately .Do this in the evenings or nights.
Standing water during daytime may reach temperatures not tolerable to young saplings. The bottom leaves will become brown / yellow and die.
Another reason is want of nitrogen . Did you use cow dung liberally ? Excess use of compost / cow dung affects young saplings .
