Growth and development of mustard genotypes as influenced by different thermal environment under Chhattisgarh plain climatic conditions

Abstract

A field experiment was conducted Growth and development of mustard genotypes as influenced by different thermal environment under Chhattisgarh plain climatic conditions was carried out at the research farm, I.G.K.V., Raipur during rabi season of 2015-2016. The soil of experimental field was sandy loam in texture. The soil was neutral in reaction and had low phosphorus and medium nitrogen and potassium contents. The experiment was laid out in Factorial Randomized Block Design with three replications and two factors. First factor (thermal environment) viz., D1-25.11.2015, D2–05.12.2015 and D3–15.12.2015, second factor was varieties (3); PT-30 (V1), PT-303 (V2) and Pusa Mustard-26 (V3). It was observed that the days required for attaining various phases from sowing to maturity stage varied considerably in different thermal environments. Early sowing on 25th November took more days to mature as compared to delayed sowing i.e. 5th and 15th December. Growth and development was greatly influenced under different thermal environments. Significantly maximum growth was recorded from variety Pusa Mustard-26 in crop sown on 25th November and minimum was recorded in PT-30 in crop sown on 15th December.
