5.5.3.2 Assessing the leaf area index and biomass production in mustard varieties by the use of thermal time
Based on the field experiments with two Brassica varieties (Pusa Jaikisan and Bio-169-96), thermal response curves were developed using thermal time as a base. The best-fit polynomial second order regression equations were developed taking LAI as a dependable variable with the thermal time, viz., growing degree days (GDD) as an independent variable. The growing degree days could explain 96% to 99% variation in LAI in different treatments in Pusa Jaikisan and Bio-169-96 in October 15 sowings and 95% to 98% in October 30 sowing. When the 2006-07 season data were pooled with the previous crop season data (two varieties and two seasons), the correlation coefficients were highly significant (at 1 per cent). Hence, the regression equations were developed which will be of immense use in assessing the leaf area index by the use of the thermal time, without destroying the plant samples. Similarly, by the use of thermal response curves of biomass production, regression equations were developed to assess the biomass production at different intervals of time, without destroying the plants. However, caution is required when the data over varieties are pooled, as they might lead to considerable errors. It would be worthwhile to develop equations, which are variety and location specific. These types of quantitative relationships would go a long way in dynamic crop simulation modeling studies.
