Abstract:A study was conducted to find out the “Effect of growing media and biofertilizers on seed germination, seedling vigour in cashew (
Anacardium occidentale L.)” at Cashew Research Station, Bapatla, Andhra Pradesh in the year 2021-22. The experiment was laid out in a factorial randomized block design (FRBD) with two replications containing of twenty four treatment combinations which consists of two factors
viz., growing media at four levels (M
0: soil + sand +FYM (2:1:1) M
1: soil + sand+ vermicompost (2:1:1) M
2: soil + sand + FYM + cocopeat (2:1:1:1) M
3: soil + sand + vermicompost + cocopeat (2:1:1:1)) and biofertilizers at six levels (B
0: SSP @ 10 g/Bag +N:P: K (19:19:19) @ 5 g/lit (foliar spray) + Formula 4 @ 5 g/lit (foliar\spray), B
1: Phosphorus Solubilizing Bacteria, B
2: Vascular Arbuscular Mycorrhizal fungi, B
3:
Pseudomonas fluorescence, B
4: Arka Microbial Consortium, B
5:
Trichoderma viride), by adopting standard methodology, observations on germination and growth parameters were recorded.
Interaction effect of growing media contained soil + sand + vermicompost + cocopeat (2:1:1:1) inoculated with bio fertilizer Arka Microbial Consortium (M3B4) had recorded highest germination per cent (96.00% at 30 DAS), maximum number of leaves per seedling (7.00 and 9.60 at 30 and 45 DAG respectively), stem girth (1.55 cm and 1.61 cm at 30, 45 DAG respectively), plant height (28.35 cm and 38.95 cm at 30, 45 DAG respectively), chlorophyll content (59.84 SPAD units at 45 DAG), survival per cent of seedlings (95.00% at 45 DAG) were recorded against the lowest germination percentage and growth parameters in the treatment M0B0 (soil + sand +FYM (2:1:1) inoculated with SSP @ 10 g/Bag +N:P: K (19:19:19) @ 5 g/lit (foliar spray) + Formula 4 @ 5 g/lit (foliar\spray).
