Abstract

Porang plants ( Amorphophallus onchophyllus ) is a shrub ( herb ) that the leaves grow armpit bulbil as a breeding tool. In addition to using bulbil porang can also reproduce by using bulbs and seeds. Bulbs to be harvest as result because it has glucomanan compounds that high economic value. Currently there porang tuber production sold to employers to be exported abroad in the form of chips filled with a gathering of farmers iles - iles that grows wild in the environment and forestry plantations. Intensive cultivation efforts should be supported by the availability of seedlings. Therefore, it needs to be study with seedlings originating from sources other than the tubers, ie with bulbil. The purpose of the study is 1) Knowing the effect of combined treatment of sitokinin (CPPU) concentration and dose of NPK fertilizer on growth and yield porang 2) Knowing sitokinin (CPPU) concentration effective in improving plant growth of porang and 3) Knowing the optimum dose of NPK fertilizer on plant growth porang. This experiment is a factorial experiment with 2 (two) factors which are arranged in a completely randomized design (CRD) and repeated 4 times. The first factor is the concentration CPPU (K), which consists of : K0 = Without CPPU (control), CPPU 5 ppm = K1, K2 = CPPU 10 ppm, 15 ppm CPPU = K3 and K4 = CPPU 20 ppm. While the second factor is the dose of fertilizer N , P and K (P) consisting of : P1 = dose of NPK fertilizers (Urea 15 g, SP36 7.5 g, KCl 7.5 g), P2 = dose of NPK fertilizers (Urea 20 g , SP36 10 g, 10 g KCl) and P3 = dose of NPK fertilizers (Urea 25 g, SP36 12.5 g, 12.5 g KCl). Observations were made on growth and development, as well as crop yields porang, which consists of: plant height (cm), leaf canopy width (cm), stem diameter (cm), number of bulbil, bulb diameter (cm) and weight of tubers per plant. The results showed that: 1) There was no significant interaction of all variables observation, 2) Concentration CPPU very significant effect on canopy leaf width and number of bulbil. Concentration CPPU 20 ppm produces a wide canopy of leaves and number of bulbil highest with increased width of the leaf canopy by 38 % and increase in number of bulbil by 87% compared with controls. 3) Fertilizer doses very significant effect on canopy leaf width and number of bulbil. Dose of NPK fertilizer 25 g urea, 12.5 g SP36 and 12.5 g KCL (P3), shows the results of the leaf canopy width and number of bulbil highest with increased width of the leaf canopy by 34% and increase of number bulbil by 67% compared with fertilizer treatment 15 g of urea, 7.5 g SP-36 and 7.5 g KCL (P1).

Abstract

One of the low production of potatoes is the lack of land carrying capacity. The availability of nutrients greatly affects the growth and yield of plants. During this time excessive and continuous use of inorganic fertilizers can lead to a decrease in soil fertility rates. Paitan plants have only been used as a fence plant and still not widely used as a producer of organic nutrients, especially in potatoes. Utilization of mexican sunflower as a supplier of organic materials can be done easily and efficiently because mexican sunflower plants are very easy to get and grown widely. This plants are widespread in the region of East Java. The purpose of this research is to obtain the potential of paitan as a supplier of organic materials to increase growth and yield of granola potato optimum. This study used experimental method with Randomized Group Design (RGD). Treatment using mexican sunflower dose (D) consists of: D0 = Control, without fertilization, D1 = 120 kg N/ha equivalent to fresh mexican sunflower 5.882 ton/ha, D2 = 175 kg N/ha equivalent to fresh mexican sunflower 8.578 ton/ha, D3 = 230 kg N/ha equivalent to fresh mexican sunflower 11,273 ton/ha, D4 = 175 kg N/ha Urea equivalent to 380 kg/ha, P2O 149.76 kg/ha, K2O 100 kg/ha. The results of the study obtained mexican sunflower with a dose of fertilization 11,273 ton/ha equivalent to 230 kg N/ha (D3) can produce growth and yield of the highest potato crops. Mexican sunflower as an organic fertilizer can improve soil fertility and be able to provide nutrients to plants.

Abstract

The extreme evapotranspiration on plants and soil surface is a factor that affects plant growth and production. Specifically, water loss in soybean plants affects the ABA content (abscisic acid) and potassium content in the plant. This study aims to evaluate the content of abscisic acid and potassium as indicators of drought stress in soybean plants. This study was designed following the 1-factor experimental rules and using a completely randomized design. The treatment factor is giving of water consisting of A0 = Giving water 100% normal needs, A1 = Giving water 75% normal needs, A2 = giving water 50% normal needs, A3 = giving water 25% normal needs. The results showed that ABA biosynthesis increased in plants experiencing drought stress, the decreasing giving of water, the ABA levels in the leaves increased. The potassium content in plants shows a positive correlation with water supply, the lower the water supply, cause the lower of potassium content. The relationship between abscisic acid content and potassium content in plants indicated that during the occurrence of water deficiency it would trigger an increase in ABA biosynthesis and this condition caused the potassium content in the plant to decrease (R2 = 0.99). Besides, the treatment of giving water had a significant effect on the variables of relative water content in leaves, number of leaves and weight of seeds per plant. The increase in ABA content and decrease in potassium content in plants is an indicator of plants experiencing drought stress.

Abstract

Purslane is an annual plant that has various benefits. This plant contains omega 3 which is equivalent to other types of vegetables. So far, purslane is still considered a weed, so it doesn't have a cultivation technique to get the results. This study aims to obtain a combination of planting media for the growth of purslane. This research is the beginning to increase the purslane omega 3 content. Because genetic factors and environmental conditions can affect the growth and development as well as the chemical content of plants. The experimental design used a completely randomized design (CRD). The planting media used were: soil, soil + husk charcoal, soil + compost, and soil + husk charcoal + compost. The treatment was repeated 4 times, so there are 12 observation units. Observations were made on the number of leaves and the number of branches. The results showed that the combination of soil+compost gave the best effect on the number of leaves and the number of branches of the purslane seedling
