Maize (Zea mays L.) is an important food crop in Indonesia as a source of carbohydrates. The extent of land conversion reduces maize productivity. The experiment aimed to increase the growth and yield of maize in Ultisol which was carried out in the experimental garden of the West Java Horticultural and Various Seed Plant Development Center from October 2017 to March 2018. The Phosphate Solubilizing Bacteria (PSB) and organic ameliorant application test used the factorial randomized block design (RBD) method consisted of two factors. The first factor is PSB and organic ameliorant which consisted of four levels, namely b0 (without the provision of PSB and organic ameliorant), b1 (BP 107 cfu mL-1), b2 (organic ameliorant 5 tons ha-1), and b3 (PSB 107 cfu mL-1 + organic ameliorant 5 tons ha-1) and the second factor is the dosage of SP-36 fertilizer consisted of five levels, namely po (without SP-36 fertilizer), p1 (100% SP-36 fertilizer), p2 (90% SP-36 fertilizer, P3 (80% SP-36 fertilizer), and P4 (70% SP-36 fertilizer). The results showed that the application of PSB (Enterobacter ludwigii + Bulkholderia vietnamiensis + Citrobacter amalonaticus) 107 cfu mL-1 and organic ameliorant dosage of 5 tons ha-1 was able to increase plant height at age 6 Week After Planting (WAP), weight of cob with and without cornhusk, and weight of 100 seeds in the framework of increasing the growth and yield of maize on Ultisols and reduce the use of inorganic P fertilizer to 90%.

AbstractPhosphorus availability is the major constraint for plant growth in the acid soil ecosystem, due to high fixation by Al and Fe. Microbial fertilizers such as phosphate-solubilizing bacteria (PSB) can increase P availability in soils for root uptake. The objective of the research was to verify the ability of four isolates of PSB isolated from acid soil to solubilize unavailable inorganic phosphate, produce phosphatase, malic acid and indole acetic acid (IAA), as well as increase plant height of maize seedling. The bioassay by growing maize seedling in liquid nutrients has been performed to study the response of seedling to PSB inoculation. The experimental design of bioassay was a randomized block design with five replications. The results showed that the isolates RR 1 and SPR 4 had a relatively high solubilizing index. Moreover, all the PSB isolates had the ability to produce phosphatase and IAA and dissolve P. The performance of PSB-inoculated seedling was better visually and the root length was increased by 66.7–74.5% compared to the control. This result concludes that the species of four isolates needs to be identified by a biomolecular method and formulated as biofertilizers for increasing the maize productivity in the acid soil ecosystem.

Ultisols has problems of low availability of nutrients, especially phosphorus. To improve soil phosphate and P fertilizer efficiency, it is necessary to develop biofertilizer such as phosphate solubilizing microbes. Phosphate solubilizing microbes (PSM) have the capability of dissolving soil phosphorus which have been adsorbed and can mineralize organic P to become inorganic P, hence increasing the avalibility of P in the soil. Phosphate solubilizing bacteria (Pseudomonas mallei and Pseudomonas cepacea) and phosphate solubilizing fungi (Penicillium sp. and Aspergillus sp) were selected based on their ability to dissolve P. The experiment was conducted at Jatinangor, West Java Indonesia to study the application of PSM biofertilizer to increase soil P and yield of maize. Experiment used a Randomized Block Design (RBD) in factorial pattern, consisting of two factors with three replications. The first factor consisted of PSM biofertilizer, which were; without PSM, 5 L ha-1 of PSM and 50 kg ha-1 of PSM.  The second factor was P fertilizer with five levels (0%, 25%, 50%, 75% and 100% dosage of recommendation). The results showed that the application of PSM biofertilizer increased soil phosphate and yield of maize on Ultisol Jatinangor.  The dosage of P inorganic fertilizers was reduced by 50%.Keywords: ultisol, maize, biofertillizer, phospate-solubilizing bacteria.

The low area for soybean plantation is still a major problem in meeting soybean needs. One of the efforts to increase national soybean production is by expanding the planting area by utilizing the sandy soil area that is still not used for soybean cultivation. This research was conducted from September-November 2020 in a greenhouse of the Agronomy Laboratory, Bengkulu University. This study aims to obtain the best dose of urea and vermicompost for the growth and yield of soybean in sandy soil. The research design used a completely randomized block design with two factors and 3 replications. The first factor was the dose of urea consisting of four levels, namely U0 = 0 kg ha-1, U1 = 50 kg ha-1, U2 = 100 kg ha-1, and U3 = 150 kg ha-1. The second factor was the dose of vermicompost, namely K0 = 0 ton ha-1, K1 = 5 tons ha-1, K2 = 10 ton ha-1, and K3 = 15 ton ha-1. The measured variables were the plant growth and the yield. Soil and vermicompost analyses were carried out before the study. The results showed that there was an interaction between the vermicompost and the urea dosages. The 100 kg ha-1 urea and the 10 ton ha-1 vermicompost treatment gave the highest plant height. The 150 kg ha-1 urea dan the 15 ton ha-1 vermicompost treatment formed the most number of branches. The highest soybean yield was given by 15 ton ha-1 vermicompost and 50 kg ha-1 urea to the total pod and the seed weight.   Keywords: sandy soil, soybean, urea, vermicompost

Mung bean is one of the leguminous plants that is very important to be developed and is a very popular crop for consumption in Indonesia. The use of inorganic fertilizer mix (NPK Phonska) is useful for increasing the production of this crop, but its continuous use without being balanced with soil improvement efforts can lead to negative effects on the soil and crop production. Thus, it is necessary to study the use of combination of inorganic fertilizers (NPK Phonska) with organic cow manure. This study aimed to determine the effects of doses of NPK Phonska fertilizer and cow dung manure on the growth and yield of mung beans. This study used a Randomized Block Design, with two factors. The first factor was dosage of NPK Phonska fertilizer mix, consisting of four levels i.e.: A0 (control, without provision), A1 (75 kg per ha), A2 (150 kg per ha), and A3 (225 kg per ha); and the second factor was composed of three levels, i.e.: K0 (control, without provision), K1 (15 ton per ha) and K2 (30 ton per ha). The experiment was done with three replications, so that there were 36 experimental units. The results showed that NPK Phonska fertilizer at a dose of 200 kg per ha (A3) and manure at a dose of 30 ton per ha (K2) gave the highest yield for all observation variables compared with other treatments, with a yield level of 1.82 tons per ha.

A pot experiment was conducted to investigate the effect of different phosphate solubilizing bacteria (PSB) with various levels of inorganic phosphorus (P) on the growth and yield of wheat with three soil at the Microbiology laboratory, Soil Science Division, Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh. Four levels of P fertilizer (P0 : Without P, P24 : 24 mg P kg-1 soil, P36 : 36 mg P kg-1 soil and P48 : 48 mg P kg-1 soil) were assigned as main factors and six PSB inoculants with an uninoculant (I0, MR1, IL1, IW1, IC2, RC1and MW1) were assigned as sub factors in a factorial CRD. The soil used for the experiment belong to three Agroecological Zones (AEZs) such as AEZ 9 from the BAU farm, Mymensingh, AEZ 28 from the BADC farm, Madhupur, Tangail and AEZ 11 from the BINA substation farm, Ishurdi, Pabna. Eight kilogram soils were taken in each of the plastic pot. PSB were applied as broth inoculants with the wheat seeds (var. Shatabdi) before sowing. Irrespective of the PSB inoculants, 36 mg P kg-1 soil gave the highest grain and straw yield of wheat pot-1 with Mymensingh and Mdhupur soil while 48 mg P kg-1 soil showed the highest wheat yield pot-1 with Ishurdi soil. Among the PSB inoculants, MR1 showed the maximum grain and straw yields of wheat pot-1 followed by MW1. The PSB inoculant MR1 with 36 mg P kg-1 soil had better performance in terms of total P uptake and grain and straw yields of wheat.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22069 J. Environ.
