Effect of plant nutrition and fruit position on seed quality of okra cv. Arka Anamika

Abstract

The field and laboratory experiments were conducted to study the effect of nutrition and position of fruit on plant growth, seed yield and quality of okra at NSP, UAS, Bangalore. The experiment was laid out in FRCBD design with 12 treatment combinations replicated thrice which four levels of nutrients N0 (100% RDF), N1 (125% RDF), N2 (150% RDF) and N3 (200% RDF) (RDF: 156.25: 93.75: 78.75 kg NPK ha-1 And thrice consisting of three fruit position top (P1), middle (P2) and bottom (P3). It was found that bottom fruits (P3) produced highest quality seeds with maximum germination (88.61%), mean seedling length (32.77 cm), mean seedling dry weight (50.32 g), seedling vigour index-I (2927) and II (4474), 100-seed weight (7.53 g) and total dehydrogenase activity (2.80), while electrical conductivity (674 μS cm-1) of seed leachates recorded minimum in seeds from bottom fruits of okra.
