The experiment was laid out in completely randomized design keeping three treatments (100%), (75%) and (50%) of Hoagland solution. The crop was grown in PVC pipes under controlled conditions. In the greenhouse, the temperature and relative humidity were maintained between 24 0C to 32 0C and 40 % to 65 % range respectively. The pH and EC of the Hoagland solution were maintained in the range of 5.5 to 6.5 and 1.5 to 2.5 dS/m respectively in the tank. The yield was best in T1 (100%) i.e 72.57 ton / ha which was comparable with T2 (75%) i.e, 69.28 ton / ha. With respect to quality parameters, there was non significant difference in moisture content, firmness and lycopene and there was significant difference in titrable acidity and TSS. The maximum value of titrable acidity and TSS were 0.16 and 7.37 respectively recorded for T1.ennullThesis
