Abstract:

An experiment was conducted in Raipur, Madhya Pradesh, India, during 2001-02 to investigate the effect of drip irrigation combined with mulches (25-µ thick) of different colours (red (T1), white (T2) and black (T3)) on the growth, yield and quality of tomato. Drip irrigation without mulch served as the control (T0). The vegetative growth parameters such as plant height (68 cm), number of primary branches (7.0), number of flowers per cluster (6.92), number of fruits per cluster (6.38), stem thickness (1.78), number of locules (5.25) and diameter of fruits (6.23 cm) were highest in T1, followed by T2 and T3. The days required to 50% flowering and fruiting times of each mulched plot were found nearly the same and earlier than that in the control plot. The quality parameters such as total soluble solids (6.82%), acidity (0.93%), juice (48.72%), moisture (97.65%), pericarp thickness (0.69) and weight (51.96 g) of fruits were maximum in T1 and minimum in T0. The yield in T1, T2, T3 and T0, respectively, was 795.67, 730.64, 702.47 and 582.42 q/ha. The water use efficiency in T1, T2, T3 and T0, respectively, was 0.96, 0.88, 0.85 and 0.70 q/ha-mm. The net seasonal income was highest (Rs 128 261) in T1, followed by T2 (Rs 101 445) and T3 (Rs 86 271), and lowest (Rs 55 165) in T0. T1 also recorded the highest benefit:cost ratio of 1.16, followed by T2 (0.91), T3 (0.78) and T0 (0.60).
