The present investigation aimed to find out the “Effect of Foliar Nutrient Application on Growth, Economic Potential Yield and Quality of Summer Cluster Bean [Cyamopsis tetragonoloba(L.)]” was carried out at Agriculture Research Farm of Faculty of Agriculture and Veterinary Science, Mewar University, Gangrar, Chittorgarh, Rajasthan. The experiment was laid out in Randomized Block Design. Replicated thrice with 09 treatment combinations, comprising like T1 Control, T2 RDF + Foliar spray of soluble NPK at 15 DAS, T3 RDF + Foliar spray of soluble NPK at 30 DAS, T4 RDF + Foliar spray of soluble NPK at 45 DAS. T5 RDF + Foliar spray of soluble NPK at 60 DAS, T6 RDF + Foliar spray of soluble KNO3 at 15 DAS, T7 RDF + Foliar spray of soluble KNO3 at 0.5% at 30 DAS, T8 RDF + Foliar + spray of soluble KNO3 at 45 DAS and T9 RDF + Foliar spray of soluble KNO3 at 60 DAS. 
The application of Foliar spray of soluble NPK on productivity was found most effective improve success on growth yield, quality and nutrient uptake of cluster bean crops. Plant height measurements taken maximum height of 32.39, 89.12 and 105.3 cm at 30, 60 DAS, number of branches (9.0) at harvest, dry matter accumulation (65.68), plant population at harvest 173.73) maximum chlorophyll content (2.691). The application of a RDF + Foliar spray of soluble NPK at 60 DAS resulted significantly higher number of pods per plan (55.10), higher number (8.63) of seed pod-1, higher test weight (35.28 g) Treatment T4 (28.67) produced significantly more harvesting index, At straw yield, T5 had a non-significantly larger straw yield (4619.7) was recorded underT5 (RDF + Foliar spray of soluble NPK at 60 DAS). T5 application (RDF + Foliar spray of soluble NPK at 60 DAS) resulted in considerably greater protein content (27.03%) and nutrient content and uptake, highest gross return (₹ 72963 ha-1), highest net return of ₹ 49603 ha-1 and highest B:C ratio (3.12) was recorded.
