Influence of biopriming for enhancing seed yield and quality in Sorghum varieties (Sorghum bicolor L. Moench)

Abstract

Sorghum is an important tropical cereal food, feed and fodder crop. It is important grain and forage crop of semiarid regions due to its high adaptability and suitability to rainfed low input agriculture. The present experiment consist of three varieties viz., SPV-2217, GS-23 and M 35-1 and nine treatments viz., To - Hydro priming, T1 - Azospirillum brasilense @ 20 %, T2 - Pseudomonas fluorescence @ 20 %, T3 - Phosphobacteria @ 20 %, T4 - Trichoderma harzianum @ 1 %, T5 - Beejamrutha @ 50 %, T6 – Vermiwash @ 2 %, T7 – Vihaan @ 5 %, T8 - Waste decomposer @ 20 %. Seeds biopriming with Pseudomonas fluorescence @ 20 % in variety GS-23 (T2V2) recorded significantly higher germination (93.33 %), seedling length (38.90 cm), seedling dry weight (347.00 mg), test weight (34.30 g), seedling vigour index I (3630.70) and seedling vigour index II (32381.00) compared to other treatment in the experiment.
