Hello Ramu Sir,
Thank yo for the schedule.
I have few more questions... please don't mind if they are silly.
As I already said I have drip irrigation set up. Now for example germination and establishment stage you said 30Kg Urea 21 KG MAP, and 9Kg MgSo4. My question is Shall I send every thing at once using century ? or do I have to split it in some manner ?
In the same way at other stages urea 210 kg's etc... all at once ? Can you please confirm.
I have 5 acer of Ratoon sugar cane crop harvested last week. Can you please suggest how to go ahead with fertigation for this? I have left all the Trash as it is in the field.
Thanks for the patience
The fertilizer dose mentioned against each crop stage is meant for entire duration of that specific growth stage ..For example the germination and establishment phase is set for 30 days . For example 30 kg Urea provided for germination and establishment phase translates into the quantity to be delivered @ 1 kg per acre per day . However here in the germination phase , the fertigation starts on 20 th day on account of the reason that the sugarcane sett produce roots to absorb water and nutrients around that time only . However the quantity to be delivered depends on the frequency of the irrigation . If daily irrigation is followed , the quantity is @ 1 kg per acre . If given on an alternate day it is 2 kg per acre , if irrigation is given once in 3 days it is 3 kgs per per acre ..The total quantity against respective growth stage is same but the quantity per day used depends on the frequency of irrigation followed
You said ratoon sugarcane .
Things to note here is
1.If you burn the trash , it produce enormous heat of around 500-600 degree Celsius that kills both soil microbes as well as dormant buds on exposed stubble s of harvested cane that in turn impact sprouting of new shoots ..
2.So you do collect all the trashes and keep it nearby the field . Attend half baring ie, breaking the shoulder of the ridges in each sugarcane rows that tear off all the old and dead roots and induce new fresh roots that helps enormously in the absorption of water and nutrients for newly sprouted shoots
3. In about 20-30 days period , observe for gaps along the sugarcane rows . If gap is found anywhere along the sugarcane rows , just pick up the new sprouts from where it has more sprouts by splitting it away and plant it where gap is noticed .
4.Here in ratoon crops use more urea right in the beginning itself . Say apply 50 kgs of urea per acre manually along the rows after halfbaring / breaking shoulder of the ridges is done
5. And you can follow the fertigation schedule as given in the attached file
6. In ratoon crop , it needs micronutrients more particularly ferrous ion .It is to be applied in the form of ferrous sulphate @ 10 kgs per acre ..or you can even deliver it to the plants through foliar spray @1- 2 grams per lit of water
