Efficiency of Endophytic bacterial culture on yield and yield attributes of groundnut

Abstract

Field experiments were carried out for three consecutive years conducted during 2016, 2018 and 2019 during kharif season at Zonal Agricultural and Horticultural Research Station, Babbur farm, Hiriyur, Karnataka, India to study the alleviation of moisture-deficit stress in groundnut by application of endophytic bacteria under rainfed conditions. The experiment was laid out in randomized block design with three replication and eight treatments. The pooled results of three years revealed that treatment having DGREB-3 culture with intercultural operations significantly recorded higher pod yield (1022 kg ha-1) as compared to control (693 kg ha-1) and it is on par with any DGREB culture (T2) with two intercultural operations (909 kg ha-1). Any DGREB culture with two intercultural operations significantly recorded highest nodulations at 30 and 60 days (50.2 and 57.8) as compared to control (20.6 and 33.7). In case of higher gross returns (Rs. 46,565), net returns (Rs. 16,997) were recorded with DGREB-3 culture with intercultural operations. Whereas highest B:C (1.66) was recorded with any DGREB culture with two intercultural operations.
