Influence of integrated nutrient management on seed quality of coriander (Coriandrum sativum)

Abstract

The experiment was carried out during winter (rabi) season of 2016–17 and 2017–18 with 18 treatments comprising of inorganic fertilizers, biofertilizers and manures to compare the coriander (Coriandrum sativum L.) seed quality. The experiment was laid out in randomized block design with three replications. Results revealed that the co-inoculation of Azotobacter and phosphate solubilizing bacteria (PSB) along with recommended dose of nitrogen through vermicompost (T5) recorded significantly higher test weight, standard germination, seedling length, seedling dry weight, vigour index-I, vigour index-II, dehydrogenase activity, superoxidase dismutase, field emergence index and seedling establishment. The electrical conductivity was also recorded less in this treatment. The same treatment recorded significantly higher standard germination (31.50%), seedling length (14.09 cm), seedling dry weight (1.88 mg), vigour index-I (444), vigour index-II (59.25) and minimum electrical conductivity (696.92 μ S cm-1 g-1) after accelerated ageing of seed for 120 h at 40±1°C at 100% relative humidity. Suitable combination of organic manures and biofertilizers can be used to produce good quality coriander sees.
