Abstract
The present experiment entitled “EFFECT OF BIO-FERTILIZERS ON GROWTH, YEILD AND QUALITY OF STRAWBERRY (Fragaria x annassa Duch) cv. NABILA UNDER NET TUNNEL” was conducted at the Research Farm of the Center of Excellence for Protected Cultivation and Precision Farming in Net Tunnel at the Agriculture University, IGKV, Raipur (C.G.) to assess the impact of bio-fertilizers on growth parameters, yield and quality of strawberries. The investigation was laid out with 12 treatments which replicates thrice under randomized complete block design. The trial had 12 different combination of bio-fertilizers i.e. T0 : RDF (Control), T1: RDF + Azospirillum (@7 kg/ha), T2: RDF + Phosphate Solublizing Bacteria (@ 6 kg/ha), T3: RDF + VAM (@10 kg/ha), T4: RDF + Azotobacter (@7 kg/ha), T5: RDF + Azospirillum (@7 kg/ha) + Phosphate Solublizing Bacteria (@6 kg/ha), T6: RDF + Azospirillum (@7 kg/ha) + VAM(@10 kg/ha), T7: RDF + Phosphate Solublizing Bacteria (@ 6kg/ha) + VAM(@ 10 kg/ha), T8: RDF + Phosphate Solublizing Bacteria (@6 kg/ha) + Azotobacter (@7 kg/ha) and T9: RDF + Azotobacter (@7 kg/ha) + VAM (@10 kg/ha), T10: RDF + Azotobacter (@7kg/ha) + Phosphate Solublizing Bacteria (@ 6 kg/ha) + VAM (@10kg/ha) and T11: RDF + Azospirillum (@7 kg/ha) + Phosphate Solublizing Bacteria (@6 kg/ha) + VAM (@10 kg/ha).
Treatment T5 (RDF + Azospirillum (@7 kg / ha) + Phosphate Solubilizing Bacteria (@6 kg / ha) has recorded best for growth parameters i.e. plant height, plant spreading in East-West and North-South direction and number of leaves per plant, whereas the lowest value was noticed in treatment T0 : RDF (Contorl). Earliest flowering, fruiting and fruit maturity was seen under the treatment T11: RDF + Azospirillum (@7 kg/ha) + Phosphate Solublizing Bacteria (@6 kg/ha + VAM @10 kg/ha), while late flowering, fruiting and fruit maturity was observed under control.
Flowering and physical parameters of fruit i.e. number of flowers, number of fruits per plant, fruit length, diameter, volume and weight of fruit were significantly influenced under the treatment T11: (RDF + Azospirillum (@7 kg / ha) + Phosphate Solublizing Bacteria (@6 kg / ha) + VAM (@10 kg / ha) whereas, the minimum value for the same was observed under control (T0).
As regard yield, the yield (355.84 q/ha) was obtained under the treatment T11, which was found highest among rest of the treatments. Moreover, the control plots registered the lowest yield (196.23 q / ha). The chemical composition of strawberry fruit i.e. total soluble solids, sugars (Total, reducing & non-reducing) and ascorbic acid content was found maximum under RDF + Azospirillium @ 7 kg/ha + Phosphate Solubizing Bacteria (@ 6 kg/ha) +VAM (@10 kg/ha), However, the minimum fruit acidity (0.42%) was observed under the superiority of same treatment.
The treatment T11 (RDF + Azospirillium @ 7 kg/ha + Phosphate Solubizing Bacteria (@ 6 kg/ha) + VAM (@10 kg/ha) registered highest benefit cost ratio (4.20:1), while the lowest value (2.20:1) was observed in RDF + control.
