Effect of bio-fertilizers growth, physiological parameters, yield and quality of brinjal cv. Surati Ravaiya

The present experiment was carried out on brinjal cv. Surati Ravaiya during rabi season 2006–07 with objective to know the effect of bio-fertilizers on growth, yield, quality and physiological parameters. The treatments comprised of bio-fertilizers and chemical fertilizers, viz., T1 (100% RDF, control), T2 (100% RDF + Azospirillum), T3 (75% RDF + Azospirillum), T4 (100% RDF + Azotobacter), T5 (75% RDF + Azotobacter), T6 (100% RDF + Azospirillum + PSB), T7 (75% RDF + Azospirillum + PSB), T8 (100% RDF + Azotobacter + PSB), T9 (75% RDF + Azotobacter + PSB), T10 (100% RDF + Azospirillum + Azotobacter + PSB) and T11 (75% RDF + Azospirillum + Azotobacter + PSB) were tested in Randomized Block Design with three replications. The bio-fertilizers @ 2.0 kg ha¹ were mixed with fine soil and applied as per treatment. Regarding growth parameters, plant height at 60 DATP and at harvest and number of branches per plant were found maximum with 100% RDF + Azospirillum + Azotobacter + PSB, which was followed by 75% RDF + bio-fertilizers. An initiation of flowering was not affected by different bio-fertilizers treatment with chemical fertilizers. Like growth parameters, yield attributes and TSS were found superior with same treatment. Fruit weight and crude protein were not affected by these treatments. Maximum range of all physiological parameters like photosynthetic rate, transpiration rate, stomatal resistance, internal CO₂ concentration and leaf temperature at flowering were obtained in treatment of 100% RDF + Azospirillum + Azotobacter + PSB.
