Biofertilizer is one of the substances that consist of living microorganisms such as bacterial, actinomyces and fungi. These could be helped plants increasing essential elements and encourage growth. Rhizobium are a type of bacteria that conformation a symbiotic relationship with legume plant. This bacteria not only fix nitrogen but also are involv...

The Northern Thailand is one of the locations where fruit crops have long been grown, for many decades. At this present, organic farming and good agriculture practices (GAP) are considered for improving yield and quality as sustainable practices to reduce environmental impacts. On the organic system, soil fertility is conserved largely with manure...

Inthasan, J., Santasup, C. and Dechjiraratthanasiri, C. (2023). Co-rhizobium inoculation and Phosphate fertilizer management on nitrogen fixation and yield of mungbean. International Journal of Agricultural Technology 19(2):447-458. Abstract TSP (triple superphosphate) applications combined with Rhizobium (SB2) produced the highest nodule dry weigh...

The effects of different rhizobium strains on nitrogen fixation of mungbean were assessed by ureide and 15 N abundance methods. Three genotypes of mungbean (MJU3, KPS2 and CN72) were used as the main plot factor and three rhizobium strains, viz. Bradyrhizobium sp. (SB1), Bradyrhizobium elkanii (SB2) and Rhizobium sp. (SB3) plus an uninoculated cont...

To study the importance of zinc and boron to the nutrient content of coffee (Coffea arabica) leaves and yield of coffee at Maerim district, Chiang Mai, Thailand, a field-level study was conducted. Six foliar treatments were laid out in a randomised complete block design: control (Nitrophoska, formula 15-15-15 (C)), C+Ca-B, C+borax, C+ZnSO4, C+Ca-B+...

The study of rhizobium co-inoculated with arbuscular mycorrhiza and phosphate solubilizing bacteria on peanut growth in pot experiment was laid out on completely randomized design (CRD). The experiment consisted of 5 treatments; 1) control (without microorganism), 2) rhizobium (R: Rhizobium sp.),3) R + arbuscular mycorrhiza (R+AM),4) R + Phosphate...

The study was conducted to determine the effects of rhizobium and Arbuscular mycorrhiza fungi (AMF) on the growth of three cowpea varieties (Vigna unguiculata L. Walp.). The cowpea inoculated with three Rhizobium strains (R14, R41 and R55) and four AMF strains (AMF1, AMF2, AMF3 and AMF4) were evaluated with a pot experiment under greenhouse conditi...

ABSTRACT Aims: Native rhizobia from root nodules of mungbean could reduce atmospheric nitrogen to ammonia for assimilation. The objective of this study was to find the best native rhizobium from mungbean. Methodology and results:Three rhizobia isolates from three mungbean varieties (Maejo 3, Khampangsan 2 and Chainat 72) were collected from 10 unda...

Fly ash is a waste product of the electrical power plant at Mae Mau in Lampang province, northern Thailand. This experiment was conducted in order to study the responses of selected soil types on fly ash applications with respect to chemical properties. The experiment was based on soil samples from two depths, 0-0.1 m. and 0.1-0.25 m. depths of thr...

The research was undertaken to study the effect of application of different rate of organic fertilizers on broccoli. There were five treatments in total consisting of inorganic, organic fertilizers and blank control. The organic treatment included compost applied with three different rates of chicken manure tea (CMT) i.e. (0 ml/week, 100 ml/week an...

Lychee cultivation in northern Thailand is a popular method to earn income for farmers. Fertilizer and soil amendments will always be recommend for improving soil properties. This experiment examines responses of selected soil amendments and NPK fertilizer on nutrients leached under lychee canopies of an Acrisol soil. An experiment was conducted wi...
