| Abstract | The experiment entitled “Wicking bed irrigation in tomato (Solanum <br/>lycopersicum (L).)” was conducted with the objectives to standardize the height and <br/>media filled reservoir in wicking bed system, to evaluate the performance of tomato as a <br/>test crop under wicking bed (WB) system and to work out the economics. The <br/>experiment was carried out from December 2020 to April 2021 in farmer’s field at <br/>Varkala in Thiruvananthapuram district. <br/>The experiment was laid out in completely randomized design with 8 treatments <br/>replicated thrice. The treatments were T1 – gravel WB 100mm + geotextile inter liner <br/>(GT) + soil bed (SB) 200 mm; T2 - gravel WB 150mm + GT + SB 300 mm; T3 - coconut<br/>shell WB 100 mm + GT + SB 200 mm; T4 - coconut shell WB 150 mm + GT + SB 300 <br/>mm; T5 - gravel + coconut shell (1:1) WB 100 mm + GT + SB 200 mm; T6 - gravel + <br/>coconut shell (1:1) WB 150 mm + GT + SB 300 mm; T7 - SB 200 mm conventional <br/>irrigation; T8 – SB 300 mm conventional irrigation. Soil bed was prepared by mixing soil, <br/>coir pith compost and FYM in the ratio 2:1:1. Nutrition was provided as per the organic <br/>POP of KAU. Tomato seedlings of variety Vellayani Vijai was used for transplanting. After <br/>transplanting, all treatments were surface irrigated for two weeks. Irrigation was given in <br/>the wicking bed based on the water level in the reservoir.<br/>The growth characters viz., plant height, number of branches, stem girth and leaf<br/>area were recorded at 30, 60, 90 days after transplanting (DAT) and at harvest. At 30 <br/>DAT and 60 DAT, taller plants (59.32, 93.25 cm, respectively) were observed in coconut<br/>shell WB 150 mm + GT + SB 300 mm (T4) and at 90 DAT and at harvest gravel + <br/>coconut shell (1:1) WB 150 mm + GT + SB 300 mm (T6) recorded the taller plants. <br/>Number of primary branches per plant were higher in the treatment coconut shell WB <br/>150 mm + GT + SB 300 mm (T4) in all the growth stages. Stem girth was not influenced <br/>by the wicking bed and surface irrigation treatments except at 60 DAT. At 60 DAT, stem <br/>136<br/>girth recorded in all the treatments were on par, except soil bed 200 mm with <br/>conventional irrigation (T7). Leaf area was not influenced during early stages of growth. <br/>Higher leaf area (797 cm2<br/>) was observed for T2 at 90 DAT and at harvest (768 cm2<br/>).<br/>Coconut shell WB 150 mm + GT + SB 300 mm (T4) recorded higher dry matter, root <br/>weight and root volume. The longest roots (17.30 cm) were recorded in gravel WB <br/>150mm + GT + SB 300 mm (T2).<br/>Flower clusters per plant was significantly more in T2 (31.67) which was on par with <br/>T1, T5 and T6. Coconut shell WB 150 mm + GT + SB 300 mm (T4) recorded higher <br/>number of flowers per cluster (10.67). The treatments, coconut shell WB 150 mm + GT + <br/>SB 300 mm (T4) and gravel + coconut shell (1:1) WB 150 mm + GT + SB 300 mm (T6) <br/>took less number of days (37.83) to reach 50 per cent flowering. Fruits were longer (4.35 <br/>cm) in T3 and fruit diameter was higher (11.63 cm) in T6. T4 (coconut shell WB 150 mm <br/>+ GT + SB 300 mm) recorded more fruit weight (41.50 g) and remained statistically on <br/>par with T2 and T6.<br/>The analysed data revealed that higher yield per plant (1153 g) and more number of <br/>pickings were recorded in T4 which was on par with T2. Harvest index was higher in <br/>larger reservoir depths. Significantly higher (20.64 mg 100 g fruit-1<br/>) ascorbic acid content <br/>was recorded in T4 and T5. Total soluble sugars and titrable acidity were not influenced <br/>by wicking and surface irrigation treatments.<br/>Soil pH, organic carbon, P and K content were not influenced by wicking bed and <br/>surface irrigation treatments. Bulk density was higher (1.31 Mg m-3<br/>) in gravel + coconut <br/>shell (1:1) WB 150 mm + GT + SB 300 mm (T6) which was on par with T3 and T5. <br/>Surface irrigation treatments (T7 and T8) recorded lower EC value (0.86 and 0.95 dS m-1<br/>, <br/>respectively). Available nitrogen content was significantly higher in T4 (coconut shell <br/>WB 150 mm + GT + SB 300 mm) and was comparable with T1 and T5. Plant uptake of N <br/>and P was higher in T4 (coconut shell WB 150 mm + GT + SB 300 mm) and K uptake <br/>was higher (10.18 g per plant) in T2 (gravel WB 150mm + GT + SB 300 mm) which was <br/>on par with T4.<br/>137<br/>Water requirement of tomato varied with the treatments ranging from 480.06 mm (T4) <br/>to 568.22 mm (T7). The frequency of irrigation varied from 9 in larger reservoir depth to <br/>35 in surface irrigation treatments. T4 recorded the lowest water requirement (480.06 <br/>mm) and the highest total water use efficiency (65.05 kg ha-1 mm-1<br/>). The economic <br/>analysis revealed that T4 (coconut shell WB 150 mm + GT + SB 300 mm) recorded the <br/>highest net returns per plant (₹ 46.23) and BCR of 2.00.<br/>From the study, it could be concluded that, tomato can be successfully cultivated in <br/>wicking bed system. Among the wicking beds, coconut shell filled reservoir of 150 mm <br/>depth + geotextile inter liner + 300 mm soil bed depth could be recommended for tomato <br/>cultivation considering the yield, quality, water use efficiency and economics. |
