Abstract

Hydroponic system is an alternative agricultural cultivation technology and a potential system to overcome the decreasing availability of land. Tomato production with this system has its own market segment. Balanced nutrient management combined with inoculation of functional microbial consortium (N-fixing bacteria and phosphate solubilizers) is one of the efforts to increase tomato production in a hydroponic system. This experiment aimed to examine the effect of microbial consortium and hydroponic nutrition on tomato plant growth, Azotobacter spp. population, N uptake and tomato yield. The research design used was a factorial randomized block design (RBD) consisted of two factors. The first factor was the dose of the microbial consortium, consisting of three levels (0 mL/polybag, 5 mL/polybag, and 10 mL/polybag. The second factor was the nutritional dose consisting of three levels (0 mL, 250 mL, and 500 mL). The experimental results showed that there was no interaction between the microbial consortium treatment nutrients on hydroponic plants’ height, N uptake, Azotobacter spp. population and tomato yield. Increased nutrient dose significantly increased N uptake, with the highest yield at 500 ml/pot. But the increased nutrients dose did not lead to significantly different tomato yields. Inoculation of the microbial consortium did not significantly increase all tested parameters.

Abstract

As a staple in Indonesian diet, rice demand increase along with the population growth. Therefore, in order to fulfill the continuous increase, researches were conducted to increase land productivity. The increase of growth and productivity of upland rice with the application of Azospirillum sp. and Azotobacter sp. in compost, Azolla, and rice bran carrier were studied. Nitrogen fixer were applied as a biofertiliser as a mean to supply available nitrogen for upland rice growth. This research was conducted in Ciparanje Experimental Field and Soil Biology Laboratory, Faculty of Agriculture, Universitas Padjadjaran. In this research, Randomized Block Design was used to analyze two factors: urea dose (100% and 50%) and Nfixer bacteria in various carriers (individual carrier and combination of liquid inoculant, green compost, Azolla compost, rice bran). The result showed an interaction between two factors towards the grain weight of upland rice. The application of 100% urea dose showed higher result compared to 50% urea dose on grain weight. N fixer bacteria combined with compost, Azolla, and rice bran carrier gave the highest result on the number of tillers, chlorophyll content, and grain weight.

Abstract

Dairy farming waste in high volume especially in the form of flushing slurry can be unmanageable. Flushing slurry is lower in organic matter content compared to solid waste due to water saturation. In order to enhance the utilization, flushing slurry can be converted in liquid organic fertilizer with higher nutrient content. King grass (Pennisetum purphoides L.) plant is commonly used as livestock feed especially dairy cow in South Bandung area. The experiment was conducted between March to June 2018 in Pangalengan, South Bandung. The result shows no significant different between control specimen and liquid organic fertilizer teratments in plant hight, number of leaves, root weight, and root length. Although notable amount of plant leaves was demonstrated in D treatment compared to than that of control.

Abstract

Azospirillium is a genus of non-symbiotic N fixer bacteria, known as a biological fertilizer inoculant. The quality of Azospirillum sp. inoculant often decrease when applied outside its original habitat. Therefore, it is necessary to maintain the viability and increase its effectiveness. One way that can be done is by adding organic material as additives as a source of energy for bacteria. Potential organic materials can be used as additives to stimulate the viability, activity and effectiveness of Azospirillium sp. are coconut water, molasses and bran. The organic material contained elements such as C, N and P as the source of nutrients for Azospirillium sp. which was inoculated in Soybean (Glycine max L.) plants. This experiment aimed to examine the effect of additive application on Azospirillum sp. population, root nodules, and seed weight of soybean plants (Glycine max L.) on Jatinangor Inceptisols. The experimental design used was Randomized Block Design (RBD) consisted of combination between of Azospirillum sp. and additives type, namely molasses, coconut water and bran. The results showed that the application of a mixture of bran, molasses, and coconut water attracted the population of Azospirillum sp. higher than the control treatments. Meanwhile molasses, coconut water, and additive mixtures have the potential to increase the number of root nodules and soybean pods yields. Coconut water, molasses and bran are organic materials that have the potential as additives that stimulate the activity and increase the population of Azospirillium sp. and soybean pods.

Abstract

Since Inceptisols, in general, contain low soil organic matter and major plant nutrients, inorganic fertilizers are commonly added during corn cultivation. In order to maintain long-term soil health and fertility, bioferilizer and organic ameliorant application are suggested. The addition of nitrogen (N)-fixing bacteria (NFB) can benefit plant growth through the supply of available nitrogen for plant uptake. Organic ameliorants can enhance soil chemical and biological properties. A field trial had been performed to observe the effect of biofertilizer and organic ameliorant on corn growth, N status in soil and plant, and the yield and wasteof corn. The experiment was designed in a Completely Randomized Block Design that consisted of four treatments and six replications. The treatments were 1.2 kg/ha N-fixing mixed biofertilizer, 2 t/ha organic ameliorant, and mixtures of biofertilizer and ameliorant. Control plants received neither biofertilizer nor ameliorant. The experiment results found that N-fixing biofertilizer and ameliorant increased plant height, fully-developed leaves number, soil reaction and N uptake of corn compared to the control. The total-N content was slightly increased after NFB inoculation with and without amelioration over other treatments. Plots treated with biofertilizer and ameliorant produced a higher grain weight compared to the control treatment. Corn wastes such as empty corn cob and husk weight were increased in plants treated with biofertilizer, ameliorant and a combination of both. This study suggested that the combined application of biofertilizer and ameliorant produced 66% more grain yield and 84 % more cob and husk waste compared to untreated plants.
