Abstract:
A pot experiment was conducted at Department of Agricultural Chemistry and Soil Science, College of Agriculture, Junagadh Agricultural University, Junagadh to assess the “Effect of saline irrigation water on biochemical parameters of okra (Abelmoschus esculentus L.) varieties” during the summer-2018. The pot experiment comprised of for levels of saline irrigation water (< 2.0, 4.0, 6.0 and 8.0 dS m^-1) and five genotypes of okra (Guj.Okra-2, Guj.Okra-3, Guj.Okra-5, Guj. Anand okra-6 and Pusa savani) by adopting Factorial CRD with three replications. The results indicated that the bio-chemical parameters like RWC, chlorophyll-a, chlorophyll-b and total chlorophyll were recorded significantly highest with salinity level S₁ (< 2.0 dS m^-1), whereas the proline accumulation recorded highest with S₄ (8.0 dS m^-1) at 45 DAS. In case of varieties, the proline content, RWC, chlorophyll-a, chlorophyll-b and total chlorophyll content at 45 DAS were recorded significantly highest with variety V₁ (Guj. Okra-2) as compare to other tested varieties of okra. The combine effect of variety and salinity found significant in respect of RWC, chlorophyll-a, chlorophyll-b, total chlorophyll, Na content in leaves at 45 DAS with variety V₁ (Guj. Okra-2) at salinity level S₁ (< 2 dS m^-1). The proline accumulation (1.68 µmole g^‑1f.wt.) was found significantly highest with variety V₁ (Guj. Okra-2) and salinity level S₄ (8.0 dS m^-1).
