APPLICATION OF MINERAL PLUS FERTILIZER TO INCREASE TOMATO PRODUCTION AND QUALITY IN BATURITI DISTRICT, TABANAN REGENCY, BALI PROVINCE, INDONESIA

Environmentally friendly agriculture and food health are needed to support tourism in Bali. Meanwhile, it is alleged that agricultural products do not meet the requirements, especially the quality that does not meet consumer requirements. This research refers to the Udayana University Research Master Plan, a leading field of food security. Food Security Research Roadmap, with the aim of producing appropriate technology. The research products can be implemented in activities to increase production, quality of horticultural crops and food health to support tourism. The research method was through testing the productivity and quality of tomato plants through the addition of organic fertilizers, mineral fertilizers, chemical fertilizers, and their combination. The highest production was obtained from the treatment of P6 = mineral plus fertilizer (5 tons of hill lime + 5 tons of organic fertilizer products organic fertilizer product simantri + 100 kg urea + 100 kg phonska) per ha, can increase production (34.46%). Treatment of mineral fertilization (P2) =mineral fertilizer 5 tons of hill limestone, contains the highest vitamin C (286.14 mg/kg), P2 is also able to neutralize heavy metals Cu and Mo, increase calcium content, increase shelf life, thicken tomato skin walls which Calcium sticks to tomato skin.

Mineral fertilizers can also increase the productivity and quality of melons and oranges (Lanya, 2001), papaya fruit

RESULTS AND DISCUSSION
The results of the analysis of the variance of the effect of fertilization on tomato production and quality are presented in Table 1 and Figure 2. Table 1 shows that fertilization has a very significant effect on tomato production and the number of fruits harvested.Fertilization has a significant effect on the number of fruits.In contrast to the number of green fruits, stem weight and moisture content were not affected by fertilization.This means that fertilization only affects the production of tomatoes.To determine the nutritional content, an analysis of the content of vitamin C, calcium levels and total sugar was carried out as shown in Figure 3.
of agricultural products supporting tourism is carried out through land resource management, environmentally friendly agricultural systems.Horticultural products in the form of vegetables, fruits and flowers are needed both for the consumption of the Balinese people, the need for ceremonial facilities.and fulfilling tourism needs, especially for hotels, restaurants and restaurants.For that we need quality products, environmentally friendly and healthy for consumption.The production and quality of organic fertilizers is allegedly lower than chemical fertilizers, it is also suspected that it contains coli bacteria due to animal and human manure.Research on the application of mineral fertilizers has been carried out by the research team, generally to improve the quality of local fruits such as oranges, salak, melons, papayas from 2000-2013, 2014 on lowland vegetable crops (spinach, mustard greens and kale.The results show that mineral plus fertilizer can increase the production and quality of fruits and vegetables.Therefore, in this study, the role of mineral fertilizer plus in increasing production, quality, food health and the environment for upland horticultural crops, especially tomatoes, will be tested.Research problems include: the tourism sector requires agricultural products of high quality and competitiveness, , from the aspect of production, quality, food health.and the benefits of farming results using organic fertilizers still need to be reviewed, considering the low yields and the impact on the environment.This is due to the very low content of nutrients needed by plants in organic fertilizers.So it is needed in large quantities and has the potential to damage the environment, especially COD and BOD, as well as the coli bacteria they contain derived from animal and human waste.

(
Subadiyasa et al., 2016).Papaya plants have been tested with organic fertilizers, NPK fertilizers/chemical fertilizers (600 kg ponska/ha), mineral fertilizers of 4 tons/ha and 8 tons/ha and a combination of chemical and mineral fertilizers (4 tons+300 kg NPK)/ha.This study found that: NPK fertilizer gave the highest yield (fruit per tree, number of fruit per tree) when compared to plants that were given organic fertilizer alone or without fertilizer as shown in Figure 1.The best quality, such as Vitamin C content and total sugar, was obtained from mineral fertilizer treatment.

Figure 1.Effect of fertilization on the production and nutritional content of papaya fruit of tomato plants was carried out in Baturiti District, Tabanan Regency.The location selection was based on: the area is a center for highland vegetable production.This area is designated as a sustainable food cropland(Lanya et al., 2015).Besearch materials: tomato plant seeds, organic fertilizer (simantri product), mineral fertilizer (lime hill + kitchen salt), NPK (pearl), chemicals for analysis of visamin C and total sugar.The research method used was fertilization testing in the field using eight fertilizer treatments, namely: (1) P0 = control, (2) P1 = organic fertilizer/Simantri productsld 10 tons/ha, (3) P2 = mineral fertilizer 5 tons/ha ( lime+salt), (4) P3 = chemical (NPK) fertilizer (200 kg ponska + 200 kg urea) per ha/ farmer dose, (5) P4 = combination fertilizer ( P1+P3) per ha, ( 6) P5 = combination fertilizer ( P2 + P3) per ha, (7) P6 = mineral fertilizer plus = ½ (P1 + P2 + P3), and (8) P7 = mineral fertilizer plus (½ P1 +½ P2).The plot size is 1 x 10 m = 10 m2, three replications, each type of plant has 24 plots.Parameters tested for production: height, weight and number per plot or per ha.Quality observed: water content, total sugar content, vitamin C and calcium mineral content.Statistical analysis used a Randomized Block Design (RAK), analysis of variance (ANOVA) to determine the effect of fertilization treatment on the observed parameters.The smallest significant difference test (Duncan's Multiple Range Test) at the 5% level was used to determine the difference in the mean of each parameter observed.ANOVA test and BNT test using the COSTAT program.
