Indonesia has decreased tomato production so that it cannot meet the needs of the community. Therefore, innovation is needed to meet the increasing needs of tomatoes. One way is to form polyploid plants using colchicines. In this research a factorial randomized block design (RAK) was used with two treatments, namely Varieties (Servo F1 and Gem) and Colchhisin Concentration (0, 0.1% and 0.2%) with 4 replications with a total plant total of 24 polibek. Immersion is carried out for 6 hours. Plant height, number of leaves, number of branches, number of flowers, number of fruits per plant and weight of fruits per plant were observed parameters. From the results of the analysis showed that the variety and concentration of kolchhisin did not significantly affect all parameters. Therefore, further research will be carried out to obtain the right concentration in forming polyploid tomato plants

The low-frequency tapping (d4) offers an opportunity to exploit the latex through the increments of stimulant concentration and application frequency. This study compared the yield and dry rubber content (DRC) from three different stimulant compounds i.e. etephon 5.0% (ET), polyethylene glycol 3.0% + palmitic acid 0.2% + etephon 5.0% (EN), and polyethylene glycol 3.0% + palmitic acid 0.2% (NS). A field trial was carried out at Tanah Besih Estate, North Sumatera using 17 years of age RRIM 911 clone based on Complete Block Design. The data was collected from May 2017 to February 2018. The result suggested that the ET was the strongest compound that able to generate higher yield (56.37 gt-1t-1) than EN and NS (56.37 gt-1t-1 and 34.00 gt-1t-1 respectively). Nevertheless, the high concentration tended to have a slightly lower DRC. When etephon was combined with other compounds, it lowered the effect on the yield. All treatments showed that the first and second tapping after stimulant application generated highest yield. The yield in mature leaves had lowed yield in ET and EN treatments, while NS showed a significant increase. Our result suggested that the application of high concentration of etephon was very effective to obtain the yield.

Cocoa is the source of life for more than 6.5 million farming families. Cocoa farmers in Langkat District about 2081 with an area of 2603/ha. Cocoa production in Langkat recorded about 950 kg/ha/year, but some produced about 450 kg/ha/year. In addition to the shortage of subsidized inorganic fertilizers, another problem in Indonesia’s low cocoa production especially Langkat is because cultivation was not done.Another, the attack of plant-disturbing organisms, such as Cocoa Borer (CPB) and Vascular Streak Dieback (VSD). Cocoa pod borer, Conopomorpha cramerella is a very serious pest and 80% production reduced. It was because the cocoa pod borer is difficult to control and had spread throughout Langkat. By 2018, cocoa production in Langkat about 7 kg/weeks. Biological control using black ants has been developed as a natural CPB pest agency by making ant nest of 30-40 strands of dried cocoa leaves with permanent polystyrene plastic or dry cocoa leaves and tied with rafia straps. The results showed that cocoa pods were heavy damaged under 5%. Fertilizing with Bokashi which are made of cocoa leaves, bran, husks and manure fermented with EM-4 was applied 5 kg/tree, for plant resistance to VSD disease and cocoa production increased. Farmer are commitment to their respective cocoa gardens and hope they can produce organic cocoa in the future

Seedling growth in the field is largely determined by the growth of plants during the nursery. The use of polybags should be black so that the roots in the nursery can develop optimally. Mycorrhiza are structures formed by symbiotic associations with root pathogen infections. Phosphate is a macro element that is very important for plant growth. The place of the research was conducted in the STIPAP Field Practice Field in Medan from February to June 2019. This study used a Factorial Randomized Block Design (RBD) with two series (Black and White Polybags) and two factors studied, namely: Mycorrhiza Factor (M) consists of 3 levels, M0 = 0 g / seed, M1 = 40 g / seed, M2 = 80 g / seed. Fertilizer Factor P (P) consists of 3 levels, P0 = 0 g / seed, P1 = 50 g / seed, P2 = 100 g / seed. The parameters measured were plant height, number of leaves, canopy and root dry weight, mycorrhiza infection and P nutrient content. The results showed that mycorrhiza treatment on black polybags had a significant effect on seedling height, and root dry weight. The white polybag has a significant influence on the dry weight of the roots. The application of P fertilizer on black polybag has a very significant effect on root dry weight. The white polybag has a significant influence on the dry weight of the roots. In the black polybag, Mycorrhiza interacts real and very real by giving P fertilizer to the height of the seedlings, and the dry weight of the roots. The white polybag has a very significant effect on the dry weight of the roots.
