3. Comparative performances of organic amendments on germination, growth and yield indices of three selected okra [Abelmoschus esculentus (L.) Moench] cultivars

Abstract

In recent years, organic amendments are getting prime importance as a source of plant nutrition under intensive cropping system due to its economic, environment friendly and agronomically sound nature. This study has been conducted to investigate the ameliorative role of three organic manures (cowdung, compost and vermicompost; 10, 5 and 5 tha-1 , respectively) with three okra varieties viz., BARI Dherosh-1, BARI Dherosh-2, and Pusha at the shed house condition between April to August, 2018 in Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. The entire experiment was repeated three times following randomized complete block design. Result showed that organic manures improved plant growth and yield attributes in a significant manner. However, vermicompost followed by compost resulted in overall better plant performances among which SPAD value, green pod number plant-1 , green pod weight plant-1 , seed pod-1 , and total seed yield are important. The application of vermicompost dramatically improved seed germination parameters and seedling indices. In combination, BARI Dherosh-2 with 5 tha-1 vermicompost application resulted with the best plant performances. Considering the experimental outcomes, we may conclude that vermicompost promotes growth and yield attributes of okra.
