 ABSTRACT

A field experiment was conducted during two consecutive kharif seasons of 2017 and 2018 at Agricultural Research Station, Ananthapuramu of Acharya N.G. Ranga Agricultural University, Andhra Pradesh. The experiment was laid out in a randomized block design with three replications. There were 9 treatments consisting of dryland groundnut (Without in- situ and ex- situ rainwater management), Formation of conservation furrows at every 1.2 m width at sowing, T2 + one supplemental irrigation of 10 mm when dryspell of 10 days occurs after 50 % flowering, T2 + two supplemental irrigations of 10 mm each when dryspell of 10 days occurs after 50% flowering, Shales (Beluku in Telugu) application @ 300 t ha-1 as surface mulch (first year application only), T5 + one supplemental irrigation of 10 mm when dryspell of 10 days occurs after 50% flowering, T5+ two supplemental irrigations of 10 mm each when dryspell of 10 days occurs after 50% flowering, only one supplemental irrigation of 10 mm when dryspell of 10 days occurs after 50% flowering and two supplemental irrigations of 10 mm each when dryspell of 10 days occurs after 50% flowering. Significantly higher plant height, leaf area index at all growth stages and pod and haulm yield were recorded with application of shales shales @300 t/ha combined with two supplemental irrigations of 10 mm each when dry spell of 10 days occurs after 50% flowering (T7), which was statistically comparable with application of shales @300 t/ha combined with one supplemental irrigation of 10 mm each when dry spell of 10 days occurs (T6) during both years of study. Where as, lower plant height, leaf area index, pod and haulm yield were recorded with dryland groundnut (without in- situ and ex- situ rainwater management) (T1).

Keywords: Groundnut, Rainwater management, Growth parameters, Yield.
