Generally we give chemical fertilizers through soil application but if we want to supply full dose of chemical fertilizers through foliar application only then what should be the dose of application and what should be the frequency of the application.
I tried to review the above said experiment but I didn't get a single review on it.
If somebody can guide and suggest will be highly appreciated.
....
Please see atached file consisting said research work reported in journals.
Thanks alot Dr Rajemahadik sir for sharing a valuable articles actually all are related to the micronutrients application through foliar but I want to check about the Primary nutrients N P and K.
Thanks alot sir

To some/greater extent (depending on nutreint element and soil nutrient status) one can supply micronutrients likeZn, B and Mo to crop plants through foliar application.If the soils are very poor /low in micronutients, then also it would be difficult to meet the full requirent through only foliar application.It is next to impossible to meet the primar nutrient requirent through foliar application.One can supplement primary nutrients through foliar application under cetain soil-crop-weather conditions like, flooding (N and K) and drought (N,P,K).At certain growth stages,say at flowering, in legumes one can apply P (DAP) through foliar application.One can attempt foliar application of K at grand growth stage of cereal crops like rice on soils deficient/marginally deficient in K.Foliar application of Mg may benefit crops like groundnut on soils deficient in Mg.We can not normally cut down the dose of macro/primary nutrients by planning or in anticipation of foliar application of those nutrients during later stages crop growth.
Foliar application also reduces future eutrophication problem.
Foliar application also reduces future eutrophication problem.
Thanks alot Dr Rao sir for your valuable guidance and clarification. As you suggested we should consider all the condition like crop
Status of soil nutrients, moisture status and other related factors.
Thanks for your addition sir

Dr Sagar
Actually some micronutrients may be supply full reccomonded does as foliar but macro nutrients like N, P, and K can't be supply of full dose and it's also depend to crop wise.
We are conducting expriments on this topic. After applying basal application, rest of the nitrogen is applied through foliar application. We are getting encouraging results. Wait till the results come.
