Phosphate Solubilizing

Hydroponic system is an alternative agricultural cultivation technology that able to answer the problem of narrowing farmland, decline in soil fertility, and the need of healthy foods. Production of tomato with this system has its own market segment, but it needs a specific treatment, such as preparation of planting medium, usage of fertilizer and addition of nutrient, etc. This experiment aims to determine the effect of biofertilizer consortium dosage and nutrient dosage, as well as their interaction to the population of phosphate solubilizing bacteria and tomato yield. The experiment was conducted in a greenhouse of Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, in June to October 2015. Design of experiment was arranged in factorial randomized block design consisting of two factors. The first factor was biofertilizer consortium dosage (0 mL/polybag, 5 mL/polybag, and 10 mL/polybag), and the second factor was nutrient dosage (0 mL, 250 mL, and 500 mL). The result showed that there was no interaction between biofertilizer consortium dosage and nutrient dosage to the population of phosphate solubilizing bacteria and tomato yield.ywords: biofertilizer consortium, hydroponic, phosphate solubilizing bacteria, tomato

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.

Phosphate Solubilizing

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.

Pola tanam sayuran secara tumpang sari telah dimanfaatkan secara meluas di sentra-sentra produksi  sayuran di Indonesia. Penelitian ini bertujuan mengetahui pengaruh pemupukan dan tumpangsari antara tomat dan kubis terhadap populasi Bemisia tabaci dan serangan penyakit virus kuning yang disebabkan oleh virus gemini pada tanaman tomat. Penelitian dilaksanakan di Kebun Percobaan Balai Penelitian Tanaman Sayuran, Lembang (1.250 dpl.) dari bulan Juni sampai dengan Oktober 2008. Rancangan yang digunakan ialah acak kelompok pola faktorial dengan empat ulangan. Dua faktor perlakuan yang diuji, yaitu (1) dosis pupuk (N 180 kg/ha + P2O5 150 kg/ha + K2O 100 kg/ha,  N 168 kg/ha + P2O5 146,5 kg/ha + K2O  145 kg /ha, serta  N 210 kg/ha + P2O5 183,125 kg/ha + K2O 181,25 kg/ha) dan (2) cara tanam (monokultur tomat dan tumpangsari tomat dengan kubis). Hasil penelitian menunjukkan bahwa penggunaan dosis pupuk yang tinggi dan tanaman tomat yang ditanam secara monokultur dapat meningkatkan populasi kutukebul dan serangan penyakit virus kuning dibandingkan dengan dosis pupuk yang lebih rendah. Penggunaan dosis pupuk yang tinggi tidak berpengaruh nyata terhadap peningkatan produksi tomat. Penggunaan dosis pupuk N 168 kg/ha + P2O5  146,5 kg/ha + K2O 145 kg/ha dan tumpangsari tomat dengan kubis dapat direkomendasikan sebagai komponen teknologi PHT untuk pengelolaan hama B. tabaci dan penyakit virus kuning pada tanaman tomat.<br /><br />The intercropping planting technique is widely implemented in vegetable production centers in Indonesia. The research on the application of different doses of fertilizers (N, P, and K) and the planting technique of tomato and cabbage  on B. tabaci and the yellow disease caused by gemini virus was carried out at the Indonesian  Vegetables Research Institute from June to October 2008. The objective was to determine the effect of different doses of fertilizers (N, P, and K) and tomato-cabbage intercropping on the population densities of B. tabaci and incidence of gemini virus on tomato.  A factorial randomized block design with two factors and four replication was used in the experiment. Two treatments factor were tested i.e.  (1) different doses of fertilizers (N 180 kg/ha + P2O5 150 kg/ha + K2O 100 kg/ha,  N 168 kg/ha + P2O5 146,5 kg/ha +  K2O 145 kg/ha, and  N 210 kg /ha +  P2O5 183,125 kg/ha + K2O 181,25 kg/ha), and (2) planting techniques (monoculture and tomato-cabbage intercropping). The result indicated that heigher doses of fertilizers resulted in higher population of whitefly per leaf and yellow virus symptoms on tomato compared to lower doses. Higher amounts of fertilizers did not significantly affect tomato yield. It is suggested that the dose of  N 168 kg/ha + P2O5 146,5 kg/ha + K2O 145 kg/ha, and the tomato-cabbage intercropping technique can be incorporated into the IPM program, especially for the management of  whitefly and gemini virus on tomato.<br /><br /><br />

Ultisol is low fertility soil and as low available P due to P fixation by Al and Fe. The phosphate solubilizing microbes (PSM) is the microbial group that enable realease fixed-P to soil solution and be absorbed by plant. This research was aimed to determine the effects of PSM biofertilizer and phosphate fertilizer dosage combination on soil potential P, total phosphate solubilizing bacteria (PSB) population and yield of maize (Zea mays L.) grown in Ultisols. This research used a Randomized Block Design that consist of nine treatments with three replications. The treatments were 100 kg ha-1 of SP-36 fertilizer, 50 kg ha-1 of PSM biofertilizer, SP-36 fertilizer (50 kg ha-1 and 100 kg ha-1) with PSM biofertilizer (25 kg ha-1, 50 kg ha-1 and 75 kg ha-1) repectively. The result showed that the combination of PSM and phosphate fertilizer dosage had significantly effect on PSB total population and maize yield, but did not not on  potential P. This experiment suggested that SP-36 fertilizer with 50 kg ha-1 dosage and PSM biofertilizer with 50 kg ha-1 dosage is the best combination.

Phosphate Solubilizing

Fulfilment of nutrients for plants can be maximized when fertilization, but the application of inorganic fertilizers can cause damage to the soil if the dosage is excessive. The utilization of phosphate solubilizing bacteria is an effort to increase the efficiency of phosphate fertilization that can extract phosphate from an insoluble form that becomes available. This study aimed to obtain a combination of inorganic fertilization doses (SP-36 and NPK) and the application of biological fertilizers that utilize phosphate solubilizing bacteria (PSB) to increase the population of phosphate solubilizing bacteria and P-available in the soil, as well as corn crop yields. This study used a randomized block design with nine treatments and three replications. The result showed that the application of PSB and inorganic phosphate fertilizer shows a significant effect on the population of PSB, P-available, plant height, stover dry weight, cob weight with husk and cob weight without husk, but didn’t show a significant effect on 100 seeds weight and number of plant leaves. Based on the correlation analysis, the results show a positive correlation between soil chemical properties, P-available, and corn yield.

Marginal soils have problems of low availability of nutrients, especially phosphorus. Phosphate solubilizing microbes can produce organic acid that dissolve P in the soil. Futhermore, the PSM also produce extracellular enzymes asa phosphatase that catalyze mineralization of organic P become inorganic P. Phosphate solubilizing bacteria (Pseudomonas mallei and Pseudomonas cepacea) and phosphate solubilizing fungi (Penicillium sp. and Aspergillus sp) is selected based on the ability of dissolving P and the production of growth regulators. Research at this stage aims to determine the biological fertilizer application techniques (PSB and PSF) as well as different types of P fertilizers to improve soil P available, growth and yield of maize. Field experiment on Ultisol Jatinangor implemented using a randomized block design (RBD) to test how applications PSM plus (giving 1, 2 and 3 applications) as well as the type of fertilizer P (SP-36 and rock phosphate). The results showed that the application of PSM can improve soil P-available growth and yield of maize. Application of PSM biological fertilizer could reduce the need for fertilizer P by 50%. PSM application once the application (early planting) with SP-36 dose 50% can increase content of soil P (P-available), and yield of maize on Ultisols.Keywords : maize, phosphate solubilizing microbes, Ultisols
