Biofertilizer effects in combination with different drying system and storage period on growth and production of tomato plant under field conditions

Abstract

Low soil fertility is caused by continue crop and using chemical fertilizer. The biofertilizer contains microorganism able to increase soil fertility. The purpose of this research was to investigate the effect of biofertilizer dried by different methods and exposed to different period of storage on nutrient, growth and productivity of tomato plant grown under the field conditions. The experiment was carried out at the field experimental Station, Research Center of Vegetable Crop, Lembang, Bandung West Java, Indonesia. A randomized block design was used with one factor (biofertilizer) including i.e. (B0) without biofertilizer (control), (B1) liquid biofertilizer, (B2) freeze dried biofertilizer without storage, (B3) freeze dried biofertilizer with 3 months storage, (B4) centrifuged biofertilizer without storage and (B5) centrifuged biofertilizer with 3 month storage with total combination of 18 blocks. The result showed that viability of bacterium tended to decline during storage of biofertilizer but did not significantly reduce the effect on growth and production of plant. Application of biofertilizer increased total macro and micro nutrient absorption, vegetative growth and plant production. The study suggested that application of biofertilizer improve growth and production and there was no different effect between 0 and 3 months storage of biofertilizers on plant growth.

Growth of typha grass (Typha angustifolia) on gold-mine tailings with application of arbuscular mycorrhiza fungi

“…For this reason, the existence of plant species having ability to absorb high metal concentration, known as metals hyperaccumulator, is very important. In addition, the use of microbes to induce plant growth either from bacteria (Mahfouz and Sharaf-Eldin 2007;Altuhaish et al 2014) or fungi (Augé 2001;Smith et al 2010) also increased dramatically, which may relate to the important mechanism in phytoremediation process (Rozpadek et al 2014). Many experiments also suggested that mycorrhizas fungi have important role in phytoremediation process by improving plant growth and inducing metal accumulation (Weissenhorn et al 1995;Javaid 2011;Khan et al 2014).…”

Growth, histochemical and physiological responses of non-edible oil producing plant (Reutealis trisperma) to gold mine tailings

“…It has deep roots systems and produces high amount of organic matter, which is necessary to accelerate the reclamation process (Sheoran et al 2010). Organic matters can improve soil fertility through microbe activities (Mimmo et al 2004) by decomposing mineral and organic matters and also promoting plant growth (Beneduzi et al 2012;Altuhaish et al 2014;Grobelak et al 2015).…”

Isolation and selection of P-solubilizing and IAA-synthesizing microorganisms from the rhizosphere of Guanandi (Calophyllum brasiliensis)

“…Tsavkelova et al (2012) reported that IAA and other phytohormones production depend on the stage of colonization, host plant and fungus infection strategy. Altuhaish et al (2014), reported the existence of plant hormones produced by rhizobacteria that improves growth and development of root cells, to become more extensive absorption, which in turn to increase plant nutrient uptake. Future studies are required to test the ability of microorganisms evaluated in this study in order to improve the growth promotion of guanandi seedlings.…”
