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.

The use of inorganic fertilizers has an important role in increasing plant growth and production. But it also causes various problems such as decreasing soil organic matter, soil acidity, soil degradation, nutrient imbalance and increasing environmental pollution. Therefore, it needs to be balanced with the provision of organic fertilizers. A field experiment was conducted to study the effect of application of various doses of inorganic and organic fertilizers on N, P, K nutrient uptake and maize plant growth. The experimental design used was a randomized block design arranged in a factorial manner consisting of two factors. The first factor is the dose of inorganic fertilizer (A): 0, 150 and 300 kg ha-1 phonska and the second factor is organic fertilizer plus (P): 0, 10, 20 tons ha-1. The two factors were combined and each treatment combination was repeated three times. The data obtained were analyzed by analysis of variance at the 5% level of significance. The results showed that there was no interaction between the application of inorganic and organic fertilizers on the growth and nutrient uptake of N, P and K. However, the application of inorganic and organic fertilizers had a significant effect on all tested agronomic traits except for plant height. Nutrient uptake of N, P and K also increased significantly due to the application of inorganic and organic fertilizers. The balance of inorganic and organic fertilizer application increases the availability of nutrients as well as the uptake of N, P, and K nutrients by maize plants.

Soybean is known for its high protein content, which is the reason why it is widely used as one of the main food sources for humans and animals. In order to optimize soybean growth, farmers tend to add excessive dosage of chemical fertilizer to this crop. Furthermore, a continuous chemical fertilizer application without organic fertilizer addition may cause a rapid depletion of nutrients in the soil. This study aimed to evaluate the effectiveness of organic fertilizer treatment to reduce the amount of urea as chemical fertilizer needed in soybean cultivation. A complete randomized design was conducted using 21 treatments of organic and chemical fertilizer in triplicate with a 4x3 m plot size. Analysis of variance was carried out to compare the means of measurement data and Duncan multiple range test (DMRT 5%) was applied. The treatment 2,000 kg ha-1 compost + 50 kg ha-1 urea (O2K2A1) resulted the highest dry yield in soybean and had significant differences with urea-only treatment. A mixture of chemical and organic fertilizers had no significant result over the yield compared to the use of chemical fertilizer only. Compost application of 1,000-2,000 kg ha-1 with urea 50-100 kg ha-1 (O2K2A1 and O 2K1A2) showed an increase in seed yield of 35-38 % with a profit reaching 333-340 USD ha-1 compared to standard treatment using urea 50 kg ha -1 + SP-36 50 kg ha-1 + 50 KCl kg ha-1 (O0K0A1).
