Abstract
The project was undertaken for study of “Effect of modeling of climatic parameters on growth and yield of tomato crop during second half of the year grown under naturally ventilated polyhouse” was conducted at the Plasticulture Farm of College of Technology & Engineering, Udaipur, transplanting of tomato crop were made from 5th July 2018 to 5th December 2018. However final harvesting was done on 20th May 2019. This study included objectives, to determine crop water requirement for tomato crop under different transplanting dates, to study the effect of climate on different dates of transplanting on growth and yield of tomato crop, modeling of effect of variation of temperature and relative humidity on growth parameters and yield of tomato crop and To estimate the water use efficiency under drip irrigated system in tomato. The experiment was laid out in randomized block design with six treatments as different transplanting dates i.e. T1: 5th July, T2: 5th August, T3: 5th September, T4: 5th October, T5: 5th November, and T6: 5th December with four replications.
The crop evapotranspiration under the treatments T1, T2, T3, T4, T5 and T6 under the NVPH were observed as 465.01 mm, 434.57 mm, 418.40 mm, 464.68 mm, 465.08 mm and 486.64 mm respectively for the entire crop periods. Transplanting on September 5th (T3) found maximum tomato yield of 118.87 t/ha. The maximum WUE (2841.13 kg/ha-cm) was observed in treatment T3 under the NVPH. Also the maximum output-input ratio (2.85) was observed in treatment T3 under the NVPH. The fruit yield per plant increased quadratically and linearly with average air temperature and relative humidity respectively from first flower anthesis to the first fruit harvest. This analysis shows that the best temperature for the growing of tomato crop i.e. 29.1oC and 75% relative humidity which gives 2971.82 g/plant yield.
Thus the overall findings of research revealed that, all the vegetative parameters, reproductive parameter and quantity parameter were found maximum in treatment T3 (i.e., transplanting of tomato in September month). For growing drip irrigated tomato, naturally ventilated polyhouse system with transplanting in September month gives better output in terms of crop yield and fruit quality. Also, at the same time productivity of water is increased without affecting yield of tomato crop.
