This study aims to obtain a doses of biological fertilizer and calcium doses that gives the best effect on the growth and production of beans (Phaseolus vulgaris L.) upright type. This experiment was carried out from February until April 2014, at the experimental field of Depatment of Agrotechnology, University of Djuanda Bogor. The experimental design used is a factorial completely randomized design with 5x3 treatments and 3 replications. The first factor biofertilizers (rich bio), A0: control (without biofertilizer), A1: Biological Fertilizer doses of 10 kg / ha, A2: biological fertilizer doses of 20 kg / ha, A3: biological fertilizer dose of 30 kg / ha, A4: microbial doses (as recommended), while the second factor doses of dolomite (CaMg (CO3) 2) consists of: B0: 0 ton / ha (without calcium), B1: 2 tons / ha, B2: 4 tons / ha. The results showed a doses of calcium 4 tons / ha showed a better response in plant height (2 weeks after plant) and the weight of the third harvest pod. Provision of calcium which is accompanied by adequate dosage of biological fertilizer can increase the wet weight and dry weight of stover.

The growth regulators of gibberellin and cytokinins are found in banana hump extract, while natural pesticides are found in the neem leaf extract. These two active ingredients can condition the growth and yield of chilies. There have not been any publications on the use of banana hump extracts and neem leaves to increase the growth and production of chili plants. The writing of this research article aims to explore the diversity of Indonesia's biological resources, among others, sword stalk banana hump extract and neem leaves which can stimulate the growth and yield of red chilies. Data analysis used a randomized block design with two variables and 3 repetitions. The first treatment used banana hump extract which consisted of four percentage levels, namely zero, fifteen, thirty, and forty-five percent, and the second treatment used neem leaf extract which consisted of four percentage levels, namely zero, fifteen, thirty, and forty-five, percent. A total of 600 grams of banana hump granules and neem leaves plus 1 liter of methanol, concentrated to a volume of 250 ml were used in this study. The results of the research showed that giving banana hump extract and neem leaves was able to stimulate the growth of leaf area so that it had an impact on increasing photosynthesis and plant metabolism. Fruit weight cannot be stimulated because, during the study, there was a long dry season, so there was a water deficit which was a limiting factor in the production of fruit formation.

The purpose of the study is to determine the effect of concentration and frequency of application of banana weevil solution kepok against red chili plants is roofed with translucent ultraviolet plastic 70% which acts as a natural growth regulator. Research on the provision of banana weevil solution covered in 70% translucent ultraviolet plastic in open land has not been found before. The growing regulators from the gibberellin and cytokinin groups were able to boost the growth and yield of chili peppers. The method of using a random design of factorial groups, as the first factor is age consists of 9 levels, namely T1: age (14) HSPT, T2: age (14.21) HSPT, T3: age (14,21,28) HSPT, T4: age (14,21,28, 35) HSPT, T5 : age (14,21,28,35, 42) HSPT, T6: age (14,21,28,35,42,49) HSPT, T7: age (14,21,28,35,42,49,56) HSPT, T8: age (14,21,28,35,42,49,56,63) HSPT, and control (T0). The second factor is concentration consists of 3 levels, namely K1 (30%), K2 (45%), and K0 (0%). The results of the study obtained concentration of K1 (30%) with the amount of T6 administration is the best result in vegetative growth of the plant height change, the number of branches, and the width of the header, while the concentration of K1 (30%) give the best results on the length of the fruit, the dry weight of the fruit, and the diameter of the fruit from other treatments. Conclusion of the application of concentration and frequency of the sea of banana weevil kepok containing regulatory substances growing on red chili plants in the field covered with ultraviolet plastic roof significantly increases the growth and yield of red chili peppers.

Efforts to increase the production of kale with a hydroponic cultivation system, the addition of nutrients is absolutely necessary for both macro and micronutrients. In addition to using AB mix nutrients, the use of other alternative fertilizers in hydroponic cultivation needs to be a big concern so that it can suppress the use of inorganic fertilizers. The purpose of this study was to determine the effect of giving various types of nutrient compositions AB mix and cow urine on the growth and yield of water spinach plants with the Nutrient Film Technique (NFT) hydroponic system . The design used in this study was a single factor randomized block design (RAK) with 4 levels of treatment of various types of hydroponic nutrients consisting of N 1 (100% AB mix ), N 2 (75% AB mix + 25% Cow Urine), N 3 (50% AB mix + 50% Cow Urine), and N 4 (25% AB mix + 75% Cow Urine). The results of this study showed that the provision of various nutritional compositions significantly affected the growth and productivity of kale except for the variable number of books. Plant water spinach given nutritional composition N 4 (25% AB mix + 75% of cow urine) showed a markedly lower in all the observed variables, while the growth and productivity of water spinach best shown in the nutritional composition of 100% AB mix but not significantly different the nutritional composition treatment was 75% AB mix + 25% cow urine and 50% AB mix + 50% cow urine. The results of this study also show that the use of cow urine has not been able to replace the use of AB mix nutrition.
