Leaf Fertilizer

One of efforts to increase tomato plant productions can be done by fertilization. Gandasil B was one of leaf fertilizer which can be used to fill P of plant so that it can increase the plant production. However, so far it has not been used for tomato plants. Therefore, it needs to do a research in order to find out the concentration and fertilization period of Gandasil B to tomato production. The research was conducted in Lowokwaru Village, Malang on March to August 2012. The research consisted of 8 treatment combinations, they are K0P1 (without treatment), K1P2 (1g/l per 1 week), K2P1 (2g/l per 1 week), K3P1 (3g/l per 1 week), K0P2 (without treatment), K1P2 (1g/l per 2 weeks), K2P2 (2 g/l per 2 weeks), K3P2 (3 g/l per 2 weeks). Each treatment was repeated four times.The research results can be concluded that there is concenration interaction and fertilization period to plant height at the age of 14 and 49 days after planting, leaves amount at the age of 14, 21, 28, 35, and 42 after planting, flowers amount at the age of 49 days after planting, branches amount at the age of 49 days after planting, and fruits amount. However, partially fertilization period treatment affects at flowering time, flowers amount at the age of 28.35 and 42 days after planting, and fruits weight. The best plant of Gandasil B fertilization results 25.98 fruits/plant with total weight of 1.23 kg/plant

Container Plant

Since initiation of the research in 1990, diverse plants (92 genera from 47 families) have been grown in the closed, insulated pallet system (CIPS). Greater growth has occurred in various embodiments of the CIPS than in the open container system (OCS) controls. Branching of roots, and of shoots of some plants, is greater in CIPS. CIPS is a closed system; there is no circulation of irrigation solutions nor effluent discharge from CIPS. Water and fertilizer movement in CIPS is plant-driven, and use is 10% of that applied in overhead sprinkler fertigation of open containers. Tomato plants are more tolerant of saline irrigation water, and greenhouse tomato production is more profitable in CIPS than in the OCS. CIPS provides several pest management alternatives.

Experiments were conducted in the last 3 years to evaluate the safety and efficacy of halosulfuron (Sandea 75WG) application under the plastic mulch within 7 days of transplanting tomato. In 2003, tomato plants were transplanted daily from day 0 through 7 after halosulfuron 0.051 kg a.i./ha application. Plant survival and height were collected. Tomato plants survived all dates of transplanting treatments. Plant height indicated that plants transplanted early were taller than those transplanted late, only because they had more time to establish and grow in the field. In 2004, tomatoes were set on a 2-day interval from day 0 through 10 after halosulfuron application. Halosulfuron 0.025 or 0.052 kg a.i./ha had no effect on plant height or yield. In 2005, an experiment was initiated to determine whether addition of trifluralin to halosulfuron under the plastic mulch will improve grass control and remain safe to tomatoes. Halosulfuron at 0.025, 0.052, and 0.1 kg a.i./ha, was applied alone and combined with trifluralin 0.63 kg a.i./ha. All treatments were applied under the plastic mulch. Tomato plants were transplanted at 6 days after application (DBT) and 0 DBT. Halosulfuron 0.1 kg ai/ha resulted in slight stunting and yield reduction of tomato, whether applied at 6 or 0DBT. However, this stunting was not statistically significant. Trifluralin didn't affect tomato yield at 6DBT and significantly increased yields at 0DBT for 0.052 and 0.1 ka a.i./ha halosulfuron rates. Trifluralin reduced grass biomass but resulted in an increase of nightshade biomass. Halosulfuron was determined to be very safe on tomato growth and yield, even if tomato was transplanted on the same day of application. Trifluralin also was found to have little or no effect on tomato growth or yield, and appears to have a potential use as an herbicide for under plastic application in tomato production.

Increasing drought, under current climate change scenarios, will reduce the sustainability of tomato cultivation in the Mediterranean region. The present study evaluates the effect of Rhizophagus intraradices inoculation on tomato plant physiology and yield in response to progressive water deficit conditions. Two commercial products (Prod1 and Prod2) containing only R. intraradices were tested at two different concentrations (1% and 5% of the substrate volume) using three methods of inoculation: (a) mixed to substrate, (b) dissolved in water, (c) spread on seedlings root blocks before transplant. The highest mycorrhization of root fragments (F%) was found with Prod2 at 1% w/w at 40 days after sowing (DAS); this product was therefore used in a second experiment to inoculate tomato plants and test their physiological response to progressive water deficit induced withholding irrigation. Phenology, plant height, stem diameter, chlorophyll content and fluorescence, whole canopy gas exchange, biomass production and partitioning and phosphorus content were investigated in inoculated and not inoculated tomato plants under well-watered and water stressed conditions. Vegetative period and plant height were shorter in inoculated than in control plants; moreover, inoculation with R. intraradices increased fruit production by enhancing chlorophyll content under water stress condition, PS2 efficiency, ETR, Fv/Fm, net photosynthetic rate and whole canopy WUE.

An intercrop is studied here as a new way of farming in soilless systems within a protected environment. To estimate the efficiency of intercropping in this cultivation system, an experiment was conducted to evaluate the effect of the electrical conductivity (EC) of the nutrient solution (2.0, 2.5, and 3.0 dS·m−1) on lettuce and tomato plants and on the agronomic and economic feasibility of the intercrop compared with monoculture. The results indicated that a moderate increase in EC from 2.0 to 3.0 dS·m−1 did not exert any important effect on tomato plant production or quality but did cause a decrease in lettuce yield in both the first and second crops. Intercropping was only feasible for lettuce when the tomato and lettuce plants were transplanted on the same day. The highest tomato (G class) and lettuce yields were achieved at an EC of 2.5 dS·m−1; this condition resulted in the highest intercrop profitability (0.53 €·m−2 more) when compared with tomato monoculture.

Two experiments were conducted to evaluate the effect of the plant regulator uniconazole on plant height, flowering, and fruit yield of vegetable transplants. In the first experiment, seedlings of tomato (Solanum lycopersicum ‘Early Girl’), pepper (Capsicum annuum ‘Jalapeno’), and eggplant (Solanum melongena ‘Millionaire’), were sprayed with water (untreated control) or with 2.5, 5, and 10 mg·L−1 of uniconazole. Five weeks after treatment (WAT), application of 2.5 mg·L−1 of uniconazole reduced the height of tomato by 17%, and of 5 and 10 mg·L−1, by 25%. The effect of 10 mg·L−1 of uniconazole on tomato plant height persisted until 13 WAT, but did not affect fruit yield. ‘Early Girl’ tomato plants treated with 10 mg·L−1 of uniconazole were still shorter than the untreated control at this time, but there were no significant differences in the number or weight of the fruit produced by the plants treated with 10 mg·L−1 of uniconazole, and the untreated controls. In contrast, as the rate of uniconazole increased, the height of ‘Jalapeno’ pepper and ‘Millionaire’ eggplant decreased. Application of uniconazole had no effect on the number of fruit produced by ‘Millionaire’ eggplant. However, treatment with 10 mg·L−1 of uniconazole reduced the number of fruit produced by pepper plants by 50%, and reduced the total weight of fruit produced by pepper and eggplant plants by 30% and 50%, respectively, compared with the untreated control. The second experiment analyzed the effects of 5, 8, and 10 mg·L−1 of uniconazole on two cultivars of tomato with different growth habit, Early Girl (determinate) and Sun Sugar (indeterminate). Application of all rates of uniconazole decreased plant height but not the final fruit yield of the two tomato cultivars.
