Data on the yield and quality of organically hybrids of tropical tomato fruits at two stages of fruit maturation

Organic and traditional cultivation techniques significantly affect the yield and quality of tomato fruit. To achieve the highest possible production of hybrid lines, the appropriate cultivation system is needed. The application of different cultivation systems was expected to improve the yield and fruit quality of three new tropical hybrid tomatoes varieties that prolong fruit shelf life. This experiment was conducted to identify the effect of the different cultivation systems on the yield and fruit quality of three hybrid tomatoes from different tropical parental backgrounds (‘Mutiara’, ‘Intan’ and ‘Ratna’). Those hybrid lines were cultivated with two farming systems (organic and conventional cultivation system), and the fruit quality was analysed at two stages of fruit maturation (Breaker and Red).


Data
The data report the fruit yield and quality of three hybrid tomato lines grown under two cultivation systems, organic and conventional. We analysed several parameters related to micro-climate and the fruit yield and quality (fruit weight per plant, fruit number per plant, fruit diameter, fruit weight, titratable acidity, fruit water content, total soluble solid, and fruit pH). Fig. 1 shows micro-climate data, and Fig. 2 shows the effects of two cultivation systems on fruit weight per plant, fruit diameter, fruit number per plant, and fruit length data. Fig. 3 shows data on fruit water content and total soluble solid (TSS). Fig. 4 reports data on fruit titratable acidity (TA) and pH. Fig. 5 shows data on b-carotene and lycopene.

Plant preparation and cultivation
Three hybrid tomato cultivars (Mutiara F1, Intan F1, and Ratna F1) were cultivated on two cultivation systems (organic and conventional system) within a 100 m 2 of tunnel type screen house at the Field of Research Center of Faculty of Agriculture, Universitas Padjadjaran, Indonesia from June 2018 to August 2018. The micro-climate condition of the greenhouse is crucial to the impact of the yield and fruit quality [4], therefore, during experimental period, air temperature and humidity were measured using an HTC-2 digital thermo-hygrometer (HTC Instruments, India). Seeds were sown in a seed tray at the beginning of the plants' cultivation with soil and cocopeat (1:1/v:v) as a growing medium. After 3e4 weeks, the tomato plants were transplanted into a 30-cm polybag with a growing medium of compost and husk charcoal (1:1/v:v). The differences between organic and conventional cultivation system were in the used of organic or inorganic fertilizer and also pest/disease control. The fertilization Specifications Analysed Experimental factors This experiment consisted of three factors (hybrid/F1 varieties, cultivation methods, and stage of fruit maturation) and was repeated four times. Three hybrid lines of tropical tomatoes varieties (Mutiara F1, Intan F1, and Ratna F1) were cultivated using two methods of cultivation (organic and conventional cultivation systems), and the fruits were harvested at two stages of fruit maturation (Breaker and Red) in triplicate.

Value of the data The data obtained here will contribute to our understanding of the relationships between cultivation systems and changes in tomato quality. The data could be used for practitioner and as basic data of further research.
was applied every week with 1 ml/L of liquid organic fertilizer for organic cultivation system and 1 g/L of NPK fertilizer for conventional cultivation system. No chemical fertilizer and pesticide were applied under the organic cultivation system. To analyse the fruit quality, the fruits were harvested at two stages of fruit maturation, namely Breaker (Br) and Red (Brþ7).

Fruit yield analysis
The same fruit maturation stage on Br and Brþ7 were harvested to be used for fruit yield and quality analyses. Several parameters related to fruit yield were analysed (i.e., fruit weight per plant, fruit diameter, fruit number per plant, and fruit length).

Analysis of the fruit water content
The fruit water content was analysed according to the method described by Aventi [5]. Briefly, fruit samples were dried using an oven with a temperature of 60 C until they reached stable, dried fruit weight. Fruit water content was measured using the following equation:  Fruit yield responses of tomato fruits from organic and conventional cultivation system. Mean ± Standard Error (SE, n ¼ 4) followed by one and two asterisk are significantly different compare to conventional cultivation system in each hybrid line according to the Student's T-Test at p < 0,05 and p < 0,01, respectively. % Fruit water content ¼ a À b b Â 100% a: fresh fruit weight (g) b: dried fruit weight (g)

Analysis of the titratable acidity (TA), pH, and total soluble solid (TSS)
TA was measured using the modified titration method described by Mubarok et al. [6,7]. Briefly, 5 g of fresh fruit was homogenised with 50 mL distilled water and then titrated up to pH 8.1 with 0.1 N sodium hydroxide. TA and pH were determined using an Advanced Bench pH Meter 3510 (Jenway, United Kingdom). TSS was used to estimate the fruit sugar content and measured with a refractometer model 3810 Pal-1 (ATAGO CO., LTD., Japan).

Analysis of b-carotene and lycopene
The b-carotene and lycopene contents were analysed at the breaker and red stages of fruit maturation, as done by Mubarok et al. [1] with some modification. Briefly, 7 mL of hexane/acetone (6:4 v/v) The content of lycopene and b-carotene were represented in micro-grams per grams of fruit fresh weight (mg/g FW).

Data analysis
This experiment was carried out with four replicates in a randomised block design. The data were represented as the mean values ± SE, and a student's t-test was performed to compare the effects of the organic and conventional cultivation systems. Fig. 4.
