i. The tomato crop is grown in shallow basaltic soil in the semi-arid region under limited water condition, the recommended deficit irrigation scheduled is 0.6 ET at vegetative stage followed by full irrigation at 1.0 ET at other growth stages for getting better yield and quality fruits if the water is available for the full growing season. The average water saving will be 10 % with an average increase in yield of 5 %. ii. If there is limited water in any one of the growth stages i.e vegetative, flowering and fruiting stage of the crop, then the deficit irrigation schedule with 0.6 ET is followed at any one stage, tomato crop was able to tolerate less moisture with decline in yield up to 2-6 % and water saving of 8-11 %. The minimum reduction in yield was observed when deficit irrigation applied during the vegetative growth stage. iii. If there is limited water in any two growth stages i.e vegetative, flowering and fruiting stage of the crop, then the deficit irrigation schedule with 0.6 ET is followed at two stages, tomato crop was able to tolerate less moisture with the decline in yield up to 15-17 %, and water-saving of 18-20 %. The minimum reduction in yield was observed when deficit irrigation applied during vegetative and fruiting stage. iv. If irrigation is with-hold for 15 days in any one of the growth stages i.e vegetative, flowering and fruiting stage, then the tomato crop was able to tolerate irrigation interruptions with the decline in yield up to 3-7% and water saving of 10-12 %. | |||
Brief Description of Technology Including Salient Features: | |||
The regulated deficit irrigation (RDI0.8 i.e 0.8xETc) did not affect the marketable fruit yield (MFY) as compared with the full irrigation (FI; 78.0 Mg ha-1). The water productivity of 19.2 kg m-3 was the maximum under RDI0.8. The MFY was improved by 4% with deficit irrigation (DI0.6) at the vegetative growth stage while DI0.6 at flowering stage showed little effect and a decline of 7% was monitored with DI0.6 at fruiting stage. The DI0.6 applied at either of two stages (i.e vegetative & flowering, flowering & fruiting and vegetative & fruiting) resulted in 14-18% decline in MFY. The crop was able to tolerate interruptions of irrigation for 15 days at growth stages and the decline in yield was only 3-7%, the highest being at fruiting stages. Fruit quality and functional food properties improved with deficit irrigation. Colour (a/b* ratio) and the concentrations of vitamin C increased by 82 and 70% with irrigation of RDI0.6 compared to full irrigation (FI). With-holding irrigation during fruit development induced colour development (52%), vitamin C content (16%) and recorded better lycopene content (10.2 mg/100 g). The total phenolics and flavonoids ranged between16 and 42 mg gallic acid equivalent/100 g and 4?10 mg catechin equivalent/100 g respectively with higher values recorded under deficit irrigation at fruiting stage. Antioxidant activity (AOA) tested with different in vitro assays revealed the positivity of deficit irrigation (DI) on the improvement of bioactive compounds. Superoxide dismutase activity was significantly higher in DI treatments at fruiting stage compared to catalase activity. | |||

Benefits/Utility | : | ||
The options of irrigation schedule will help in improving the water productivity of tomato in shallow murrum soil in the semi-arid region under limited water availability during growth season. | |||
Time Of Application Use | : | Irrigation water applied daily or one day interval through drip irrigation as per schedule and as per daily reference pan evapotranspiration | |
How To Use | : | ||
Calculate Evapotranspiration (ET) based on daily pan evaporation data and crop coefficients to find out daily Irrigation requirement. Accordingly, the time of irrigation can be worked out on daily basis. | |||
Impact, If Adopted | : | ||
Save water and electricity. | |||
