The main problem encountered by soybean crop in acid sulfate tidal lands is less availability of P, because of its chemical bond with Fe. Heavy dose of  fertilization often lead to high fertilizer residue, wich could be used for crops farming using AMF. Research was conducted to study the effect of soybean culturing technique and AMF inoculants source on growth of  soybean. The treatments consisted two factors, arranged in a randomized block design with three replications. The first factor was four inoculants sources of AMF, namely AMF and without inoculation AMF, inoculants from rhizospheres of kudzu (Pueraria javanica), sorghum (Sorghum bicolor), corn (Zea mays) and soybean (Glycine max). The second factor was culturing tehnique, namely water saturated and dry soil culture. Soybeans were grown in pots containing 5 kg soil derived from tidal land,  Simpang Village, District of Berbak, East Tanjung Jabung Regency,  Jambi Province. Results showed that the interaction saturated soil culture with inoculants from corn’s rhizosphere had positive effect on the variability of N, P and K uptake, N and P content in the plant, relative efficiency of inoculants and relative efficiency of P uptake, stem diameter, biomass dry weight, the number of filled pods and seed dry weight of soybeans. Dry soil culture with inoculants of corn’s rhizosphere had greater root colonization, but overall for the growth and grain yield of soybean, saturated soil culture with inoculants from corn rhizosphere has better effect on other growth variables.

Abstract The research aims to find the effect of biofilm biofertilizer formula and dose of organic fertilizer on phosphorus uptake and yield of shallot on Vertisols. The research was arranged in a completely randomized block design with two factors: dosage of organic fertilizer (0, 10, 20-ton ha-1) and the formula of biofilm biofertilizer (without BiO2, BiO2 1, BiO2 2, BiO2 3). Variables observed are available-P, P-uptake, bulb number, and bulb weight. Data were analyzed using F test followed by DMRT at α = 0.05. The result shows that 20-ton ha-1 organic fertilizer decomposed with biofilm biofertilizer yield highest P-uptake and plant dry weight which increases 322 and 216 % to control treatment (0.50 and 1.26 g plant-1). The use of 10-ton ha-1 of organic fertilizer yield highest bulb number and weight i.e 5.58 bulbs plant-1 and 116 g plant-1 increase 27 and 172% compared to the control. The BiO2 formula only affected to the plant height, and the use of formula 1 able to increase the plant height about 13.5% compared to control treatment.

Rice farming always experiences water shortages in dry season which result in low productivity.  In order to overcome this problem, efforts are needed in the form of irrigation technology (intermittent and water-saturated condition). The aims of this study is to determine the effect of intermittent irrigation and water-saturated condition irrigation on the production of rice plants. This study used a randomized block design (RCBD) as an environmental design with a split plot design. This study was conducted by making a plot of 4 x 6 meters, totaling to 24 plots. Between every two plots, there is a waterway 50 centimeters wide. Each plot has a waterway for water intake and discharge. Intermittent irrigation treatment was conducted by flooding the plots by water as high as 5 centimeters 3 times at 0–9 HST, 15–29 HST, 35–70 HST, and water drying was also carried out three times at 9–15 HST, 29–35 HST, and 70–80 HST. Water-saturated condition irrigation treatment was conducted by leaving the plots in a state of water saturation without any stagnant water from 0 HST until the production phase. During the treatment of intermittent and water-saturated condition irrigation, fertilizer had been given at a dose of 600 kg/ha, 800 kg/ha, 1.000 kg/ha and 1.200 kg/ha. The parameters observed in this study were the number of active tillers, the number of ears per panicle, the weight of a thousand grains, and the weight of the saplings. The results showed that intermittent and water-saturated condition irrigation did not have a significantly different effect on each parameter of rice production. The highest dry weight production both in intermittent and water-saturated condition irrigation was found in the plot with 1.200 kg/ha fertilizer and the lowest dry weight production was from the plot with 600 kg/ha fertilizer.

Temperature is a primary factor that affects the rate of plant development and has great impacts on plant growth, metabolism, and yield. A study was conducted to analyze the effects of elevated temperature on rice morphological and the physiological growth. The research was arranged in a nested randomized block design consisting of two factors, temperatures and rice varieties. Elevated temperatures were provided through the uses of different materials of plastic roof and walls to have an average and maximum temperature of 27.6 °C and 41.6 °C (T1); 28.1°C and 43.8 °C (T2), and 29.5°C and 47.1 C (T3), respectively. The study used three varieties of rice, “Ciasem”, “Ciherang”, and “IR64”. All rice varieties showed signifi cant increases in tiller number per hill and shoot dry weight, but had a decrease in the stomatal conductance, transpiration rate, and SPAD values at grain fi lling stage with the increasing temperatures. The number of tiller per hill increased when temperature was elevated from 27.6 to 28.1 and 29.5°C by about 29.9 and 21.3%, respectively.
