Effect of foliar application of water-soluble fertilizers on yield and nutrient uptake of summer finger millet (Eleusine coracana L.)

A field experiment was carried out at Shiroli farm, Regional Sugarcane and Jaggery research Station, Kolhapur during summer season of 2023 to study the effect of foliar application of water-soluble fertilizers on yield and nutrient uptake of summer finger millet in a randomized block design with ten treatments replicated thrice. The finger millet is grown in kharif season and it has good response to the fertilizers in this season and also it gives good yield. But the given experiment is undertaken in summer season to check its yield potential and response to water soluble fertilizers in summer season. Also, the present investigation focuses on ability of nutrient uptake by finger millet. The results revealed that among the various treatments, treatment RDF (60:30:30 NPK kg ha-1) recorded the highest grain and straw yield and highest mean nutrient uptake for nitrogen, phosphorous and potassium while among the different foliar sprays the application of 75% RDF (45:23:23 NPK kg ha-1) fb 2% foliar spray of 19:19:19 at tillering (45 DAS) and flowering (60 DAS) stage recorded the highest yield and mean nutrient uptake in grain and straw. The lowest values were observed with the treatment absolute control (water spray) at tillering (45 DAS) and flowering (60 DAS) stage.
