“…Under adequate water uptake rates, daily uptake rates of macro nutrients have reached the mean nutrient demand for hydroponic tomatoes. In comparison with rates of N (50 -55 me plant -1 wk -1 ) and P (15 -20 me plant -1 wk -1 ) uptake by tomato in rockwool culture (Terabayashi et al, 2004) and the uptake rates of all macro nutrients in coco-peat culture (Rincon et al, 2005) MS treatments attained the mean plant nutrient demand within the first three weeks, except for K and S. Less matured transplants (MS-3 and 4) were a little late to attain the mean K and S demands (5 -6 WAP). Hence, the high EC set point (1.8 dS m -1 ) together with high stock solution EC during early and late vegetative growth have adequately fulfilled the water and plant macro nutrient demands for tomatoes in recirculation culture, agreeing with some of the early work done under variable conditions for tomato and musk melon, recommending high EC (upto 2.0 dS m -1 ) in the growing medium, especially for the younger growth stages (Nukaya et al, 2000;Dorais et al, 2001).…”

Recirculation (closed) type hydroponics, despite its comparative eco-friendliness and cost-effectiveness, is less popular in greenhouse agriculture due to the need for close monitoring of nutrient availability within the fertigation cycle. As a practicable and low cost measure, the uptake volume based supplementation of plant nutrients at high concentrations was studied in tomato (Solanum lycopersicum L.) plants at different stages of maturity using the nutrient film technique (NFT). The plants of four age groups or maturity stages (MS), 5, 4, 3 and 2 weeks old at transplanting (MS1, MS2, MS3 and MS4, respectively), were grown in a complete hydroponic solution (Enshi), keeping the electrical conductivity (EC) set-point at 1.8 dS m-1. EC of the stock solution was maintained at 1.6 dS m-1 until the flowering stage and then changed to 1.1, 1.2, 1.6 and 1.7 dS m-1 in treatments MS1 through MS4 respectively. Young leaves were removed in MS1 while old leaves were removed in MS4 during the last two weeks to create substantially different nutrient demands among the MS treatments. The depleted volume of the supply solution was supplemented daily during the 1-2 week recirculation cycles. EC of the supply solution was monitored and the pH was adjusted to 6.5 daily. EC did not change appreciably with relatively matured stage transplants (MS1 and MS2) at the beginning due to high nutrient and water uptake rates, while in relatively young stages (MS3 and MS4) uptake concentrations (except for sulphur) were low. Under different water uptake rates, as determined by the prevailing evaporative demand, plants in all MS treatments regulated the uptake rates of macro nutrients (me day-1) by adjusting respective uptake concentrations (me L-1). Time of reaching reproductive stage and growth rate were not affected by MS at transplanting or variable EC management. Hence, N, P, K, S, Ca and Mg uptake rates of NFT grown tomato are basically governed by water uptake rate and further regulated by the uptake concentration.

“…The saving of water resulting from recycling was small compared with other studies, because the controls were given very little excess water. A study of tomato grown in coir without recycling applied 737 mm of nutrient solution and drained 219 mm (30%) over the season (Rincon et al, 2005). A study using perlite applied 630 and 225 mm in open and closed systems for a saving of 64% (Dasgan and Ekici, 2005).…”

“…Coconut coir has been found to be a suitable substrate for greenhouse tomato production. Many studies have noted equal or greater yield in coir than conventional root media (Jensen et al, 2004;Kobryn, 2002;Mazuela et al, 2004;Rincon et al, 2005). Compared with rockwool, coir has a higher cation exchange capacity that helps minimize the increase in nutrient concentrations that occurs with recycling (Iwasaki and Saigusa, 2001).…”

Effect on Yield and Quality of a Simple System to Recycle Nutrient Solution to Greenhouse Tomato

Recycling the nutrient solution used for greenhouse vegetable production can prevent groundwater pollution. Recycling could result in an accumulation or deficiency of elements that would be deleterious to plant growth, product quality, and the dietary value of vegetables. Complex fertilizer systems have been developed to maintain appropriate concentrations of all elements in recycled systems. We compared a much simpler system in which all excess solution drained from the plants was recycled without adjustment or dilution compared with a system with no recycling as a control. Crops of greenhouse tomato (Solanum lycopersicon L.) were grown in two years to compare these systems. Differences in composition of solution drained from the plants developed gradually over more than one month. The transition from vegetative to fruit growth, which coincided with warmer weather, resulted in a decreased demand for nitrate, and other nutrients, and an increase in electrical conductivity (EC) of water drained from the root zone. The composition of the fresh solution supplied to the plants was adjusted accordingly. It took a longer time to re-establish an optimum composition for recycled compared with control watering. EC tended to increase in the recycled system. Recycling decreased total yield and fruit size, but marketable yield was unaffected. The marketable fraction increased in the recycled treatment, primarily as a result of fewer fruit with cracked skin. This effect was consistent across seven cultivars. The cultivars differed in this and other defects, but they did not differ in their response to the two watering systems.

“…Since the current experiment was conducted under open eld conditions, the prevailing higher rainfall may have reduced the available N in the growth medium. On the other hand, coir dust as a substrate to grow tomatoes has 48.6% N use e ciency (Rincon et al 2004), and usually, soils with higher sand contents show low surface charge capacity and thereby a lower cation exchange capacity resulting in poor crop productivity (Noble et al 2008) showing that the growth medium also affected the growth of the tomato plants.…”

Tomato, a popular Sri Lankan vegetable, faces challenges in yields due to inadequate chemical fertilizer access, impacting growers' livelihoods. Therefore, this experiment was conducted to compare the effectiveness of the use of organic fertilizer solutions compared to the prevailing fertilizing practices. For that, recommended N, P, and K fertilizers (Chemical fertilizers), organic fertilizer solutions, organic fertilizer solutions + Albert’s solution and Albert’s solution only were tested. Two organic fertilizer solutions were prepared and applied aiming at two growth stages of the plant. The first solution included cow dung, Glyricidia leaves, and dried banana leaves. It was applied throughout the vegetative phase of the plant. The second solution included cow dung, Glyricidia leaves, egg shells, and banana peels and it was applied aiming at the reproductive stage of the plant. Results indicated that compared to the chemical fertilizers, the use of organic fertilizer solutions had a higher number of leaves per plant 12 weeks after planting (10.27 ± 0.45) and a higher root length (35.53 ± 3.22 cm) at the end of the life span. Also compared to the other treatments, they showed a higher fruit fresh weight (g) and a fruit diameter (cm). There were no significant differences (p < 0.05) among treatments for the Total Soluble Solid content (Brix %) and pH. Additionally, though the total weight of fruits per plant and the total number of fruits per plant were lower, better results were given with the plants treated with the organic fertilizer solutions.
