| Summary, etc. | Tomato is the world’s largest vegetable crop. It is one of the most important<br/>vegetable crops cultivated for its fleshy fruits and it is considered as important<br/>commercial and dietary vegetable crop. The average productivity of tomato in our<br/>country is nearly 158q per hectare. Its successful production in the tropics is,<br/>however, constrained by environmental variations especially under open field<br/>conditions. The rising temperatures and carbon dioxide concentration and uncertainty<br/>in rainfall associated with climate change may have serious direct and indirect<br/>consequences on crop production and hence food security.<br/>Objective of the study were Modeling of growth and yield of tomato and the<br/>impact of climate change based on projected climate change scenarios using DSSAT<br/>4.5 model and the impact of climate change will be studied based on projected<br/>climatic scenarios (RCP.2.6, 4.5, 6.0 and 8.5). The field was designed as spilt plot<br/>under 3 growing situations (S1-poly house, S2-rain shelter, S3-Open condition) at<br/>Central Nursery, Vellanikkara. The date of planting was on 2014 December 1st, 10th,<br/>2015 January 10th and 20th. The variety chosen was Anagha.<br/>The date of transplanting and growing environment had a significant effect on<br/>the various morphological, Phenological and yield parameters. Then greatest height<br/>was obtained by polyhouse (251.7cm) on 01 December 2014.The greatest biomass<br/>accumulation (2.23 t ha-1) inside the polyhouse on 10 December 2014 and 10 January<br/>2015. The crop transplanted in polyhouse on 01 December 2014 had the longest<br/>duration of 114 days. Maximum LAI was recorded in the crop transplanted inside the<br/>polyhouse, rain shelter (20 January 2015) and open field (10 December 2014).<br/>Highest yield 111.5 t ha-1 in the crop transplant inside polyhouse on 01 December<br/>2014.<br/>DSSAT model was validated and gave good RMSE values. The results also<br/>showed that the effect of minimum temperature would drastically reduce the yield.<br/>The increasing atmospheric CO2 concentration is likely to have some positive effect<br/>on yield, but the effect is not significant compared to the negative impact of rise in<br/>temperature. The yield of tomato (Anagha) will be reduced considerably due to<br/>climate change. |
