A two-year field study was carried out during the Kharif seasons of 2023 and 2024 at the Institutional farm of ANDUAT Kumarganj in Ayodhya, Uttar Pradesh. The research aimed to assess the effects of seed biopriming and foliar application using biocontrol agents and liquid biofertilizers on the growth and yield of Moong bean.
Seed biopriming typically involves the application of beneficial microorganisms to enhance germination potential. The present investigation was carried out on two varieties of green gram i.e., NDM-1 (Collect from ANDUAT, Kumarganj, Ayodhya, U.P) and Sikha (collect from IIPR, Kanpur, U.P) and seed biopriming with two different biocontrol agents (Pseudomonas fluorescens and Trichoderma viridae) used in different concentration and two different liquid biofertilizers (Azospirillum and Phosphobacteria @20% respectively) following randomised block design with three replication. The experiment comprised of sixteen biopriming along with hydropriming and control. Seed had been treated with control (T0), seeds soaked in distil water/hydropriming (T1); PF @ 25% (T2); PF @ 50% (T3); PF @ 75% (T4); TV @ 25% (T5); TV @ 50% (T6); TV @75% (T7); liquid ASP @ 20%(T8); liquid PB @ 20% (T9); T2 + foliar spray of PF @ 2 g/l (T10); T3 + foliar spray of PF @ 2 g/l of water (T11); T4+ foliar spray of PF @ 2 g/l of water (T12); T5 + foliar spray of TV @ 2 g/l of water (T13); T6 + foliar spray of TV @ 2 g/l of water (T14); T7 + foliar spray of TV @ 2 g/l of water (T15); T8 + foliar spray of ASP @ 2 g/l of water (T16); T9 + foliar spray of PB @ 2 g/l of water (T17).
Seed bio primed with pseudomonas fluorescens @ 75% (T4) was found very effective in both Kharif season (2023 and 2024), which enhance the plant height, no. of branches/plant, no. of pods/plant, seed yield and its attributes. The seed yield/plant for this treatment was 4.46 gm and 4.03 gm respectively followed by seed biopriming with pseudomonas fluorescens @50% + foliar application of pseudomonas fluorescens @ 2 g/l of water (T10) on 30 and 45 DAS in both kharif season as compared to non-primed seed 1.73 gm and 1.99 gm respectively.
