Abstract:

The experiment was conducted to evaluate the yield response of tomato (Solanum lycopersicum L.) to different irrigation regimes and fertigation levels under polyhouse and open field conditions. The treatment consisted of three irrigation regimes 0.95 ETc, 0.70 ETc, and 0.45 ETc. and three fertigation levels 125% RD, 100 %RD and 75% RD. The experimental design was split plot with six replications. The biometric attribute plant height was measured at harvest condition and yield attribute viz., average weight of fruit, yield in kg per plant, kg per m2 and yield in t/ha. It is seen from the data pooled over two years that the plant height of tomato under polyhouse and open field was maximum (240.5cm and 133.9 cm) due to 0.95 ETc (I1) irrigation level over other irrigation levels. Data on plant height was not significant. The minimum plant height was found in 0.45 ETc (I3). It is seen from the data pooled over two years that the fertigation level 125% RD (F1) recorded the maximum and not significant plant height (227.81 and 128.86 cm) under polyhouse and open field over other fertigation levels. The pooled data show that the average weight of a fruit of tomato was maximum (123.83 g) due to 0.95 ETc irrigation level over other irrigation levels. It was at par with all irrigation levels. Irrigation level of 0.45 ETc recorded minimum fruit weight of tomato under polyhouse condition. Data on effect of different irrigation levels on average weight of fruit of tomato were statistically not significant under open field. The pooled data shows that the effect of irrigation levels on yield in kg per plant, kgm-2 and tha-1 was statistically not significant under polyhouse and open field. The pooled data shows that the effect of fertigation levels on yield in kg per plant, kgm-2 and tha-1 was not significant under polyhouse and open field. The average water use efficiency of tomato was in the range of 49.23 to 71.27 kg/m2-m-1 and 13.55 to 31.15 kg/m2-m-1 under polyhouse and open field conditions. It was observed that the air temperature, soil temperature and light intensity was higher in open field than polyhouse. The relative humidity was higher under in polyhouse than the open field.
