A field experiment was conducted to study the effect of harvest time and dosage of organic fertilizer application on the yield of carrot (Daucus carota L.). This research was conducted at the experimental garden plants owned by Faculty of Agriculture, University of Winaya Mukti, in Tanjungsari, Sumedang. The height of this location is 850 meters above sea level with type C precipitation (rather wet). This research was conducted from January 2013 to April 2013.The design used in this research was a randomized block design (RBD) with factorial pattern consisting of two treatment factors i.e. the time of harvest (W) and organic fertilizers dosage (P) which were repeated 2 times. The first factor (W) consistedof four levels i.e. (w1) = 90 HST, (w2) = 100 HST, (w3) = 110 hst, and (w4) = 120 HST. The second factor (P) consists of four levels which are (p0) = 0 tonnes haˉ¹, (p1) = 10 tons haˉ¹, (p2) = 20 tons haˉ¹,and (p3) = 30 tons haˉ¹.This  experiment showed that there is no interaction between the application of thechicken coop organic fertilizer dosage with the harvest of the crops of carrot. However, treatment given to the 20 tons haˉ¹ dose of chicken coop organic fertilizer affected the weight of fresh roots, long tubers, the diameter of the bulbs, and the levels of vitamin C. Because the required application of the fertilizer will show the weight of fresh tubers larger, long tubers longer, heavier bulb diameter, and showed an increase in levels of vitamin C.Treatment of HST 100 time harvest affected the fresh tuber weight and the content of vitamin C, because this treatment is as needed; which then will show a heavier bulb  diameter, as well as elevated levels of vitamin C.

Peanut production has decreased, among others, due to cultivation techniques, varieties, diseases and increasingly narrow planting areas. One of the cultivation techniques to increase crop yields is the use of liquid organic fertilizer (POC) and spacing. The research method used was Randomized Block Design, factorial pattern. Consisting of two treatment factors, namely POC concentration (0, 5, 10, and 15 ml L-1 water) and spacing (30 cm x 10 cm, 30 cm x 15 cm and 30 cm x 20 cm), repeated three times. .. The results showed that: (1) there was an interaction between POC treatment and plant spacing on the number of pithy seeds and dry seed weight per plot. Independently, liquid organic fertilizer and plant spacing had an effect on plant height, number of leaves, dry weight of stover, number of filled pods, number of empty pods, percentage of filled pods and weight of 100 seeds, and (2) At a spacing of 30 cm x 15 cm, The optimum POC concentration was 13.24 ml L-1 of water, with a maximum dry seed weight of 1.436 kg plot-1 or equivalent to 2.66 tons ha-1.

Experiments aimed at studying the concentration of gibberellin and light against the growth of Orchid Plantlet Dendrobium taurulium J. J. Smit. This experiment was carried out at the Faculty of Agriculture Universitas Winaya Mukti, Sumedang West Java. Trial began in May and ended of August 2018. The experimental design used was the split plot design consists of 2 factors and repeated 3 times. Main Plot is light (P), p 1 = 40 Watt light bulbs, p 2 = 35% of the Sun's light, p 3 = 50% of the Sun's light, and the sub plot of concentration Gibberellin (G), g 0 = 0 mg L -1 , g 1 = 1 mg L -1 , g 2 = 2 mg L -1 and g 3 = 3 mg L -1 . The results are no interaction between the light and the concentration of Gibberellin to the growth plantlets Orchid Denrobium taurulium J. J Smit in In vitro. Gibberellin concentration of 1 mg L -1 gives influence on highest plants aged 12 weeks of Culture (WOC), number of leaf 4 WOC and wet weights 12 WOC. While 50% of the Sun's light, giving the influence on the amount of leaf 4 WOC and number of roots 12 WOC on plantlet Orchid Dendrobium taurulium J. J. Smit in vitro.

This research aims to determine the influence of biological Agensia Corynebacterium on growth and yield of paddy crops (Oryza sativa L.) The varieties of Inpari 13 were held in Cianjur regency with a height of 500 m above sea level from January to April in 2015. Environmental Design uses random Group draft with 6 treatments and repeated 4 times, Corynebacterium concentration treatment used is A: control (without Corynebacterium); B: 1.5 ml L-1 solution; C: 2.5 ml L-1 solution; D: 35 ml L-1 solution; E: 4.5 ml L-1 solution; F: 5.5 ml L-1 solution. Results showed that the concentration of Cocynebacterium Bioagents was influential for the high plant, the number of saplings, and leaf blight attacks. Corynebacterium concentrations are most effective for controlling Xanthomonas sp bacteria in paddy plants i.e. concentrations of 5.5 ml L-1 water, where potentially lowering the level of leaf blight attacks by 69.4% at 14 DAP, 72.71% at 28 DAP, 62.09% at 42 DAP and 66.89% at 56 DAP and increase the yield weight of 1000 grain by 9.5% and yield per meeting of 48.4%.
