A field experiment was conducted at Dryland Farm of S.V.Agricultural College, Regional Agricultural Research Station, Acharya N.G. Ranga Agricultural University, Tirupati during rabi season, 2014-15. The study aimed to enhance drought tolerance and yield through foliar nutrition in groundnut crop under moisture stress conditions. In the present study, treatments include ten foliar application of nutrients and two without foliar applications (one control irrigated and one control stress). The results revealed that, significant variations for morphological, physiological and yield parameters were observed. The foliar spray treatment KNO3 @ 0.5% recorded significantly 55 per cent high total chlorophyll content compared to control stress treatment followed by other treatments NPK- 19:19:19 @ 0.5% and KCl @ 1% with 54 and 50 per cent high total chlorophyll content respectively. Among the treatments, there significance treatmental differences were not found. Treatments showed 0.153 - 0.159 g g-1 range in total carbohydrates, 25 per cent - 26.53 per cent range in protein content and also treatments showed oil content ranges from 46.87 per cent - 48.57 per cent.

Key words: Groundnut, Moisture stress, Nutrients, Foliar application
