Cultivation Techniques

Increased soybean production both from quantity and quality continues to be pursued with extensification and intensification. During this time, fertilization is one of the cultivation techniques that is expected to contribute significantly in increasing soybean production. This study aims to determine the response of growth and production of soybean to Phosphorous (P) fertilizer and rhizobium inoculation. This research was conducted at Jl. Deli Serdang Sumatera Utara, from August-November 2017 with P fertilizer (SP-36) treatments (0, 50, 100, 150 kg/ha) and Rhizobium inoculation treatments (0, 5, 10 g/kg of seed). Variables observed were number of nodule root, number of filled pods, dry weight of seed per plant, dry weight of seed per plot and dry weight of 100 seeds. The results showed rhizobium inoculation significantly affected to the number of effective root nodules (nodules), filled pods, dry weight of seed per plant and dry weight of seed per plot with the best treatment was Rhizobium inoculation 5g/kg of seed) while the P fertilizer treatment and interaction between the two had no significant effect to all variables observed.

Inoculation Treatment

Nitrogen is an important macronutrient mineral that is needed in the largest amount by the plant and is the main limiting factor for plant development. Rhizobium is a group of bacteria capable of providing nutrients for soybean crops. When symbiotic with legume crops, this group of bacteria is able to infect plant roots and form root nodules. The study aimed to investigate the effect of Rhizobium on nodulation and growth of some soybean germplasm. The results showed no interaction between the inoculation treatment and the genotype. The significant effect of inoculation was shown by the number of nodules, nodule dry weight, root length, and root dry weight. Inoculation did not affect plant height and shoot dry weight. These traits were more influenced by genetic factors. In the condition without inoculation, the root length was higher but the root dry weight was lower. Plant height differed between the genotypes. KPT5 and KPT6 showed the highest plant height than any other genotypes. Both genotypes also had the highest shoot dry weight. The highest shoot dry weight was also achieved by KPT4.

To compare the ability of black spruce ( Picea mariana (Mill.) BSP) and tamarack ( Larix laricina (Du Roi) K. Koch) to adjust to variable edaphic conditions, as found in natural peatlands, we varied N fertilization of seedlings in a growth chamber experiment over two growing seasons and examined growth, biomass partitioning, and gas exchange. Seedlings from both species received either high N (100 µg·L–1) or low N (10 µg·L–1) in consecutive growing seasons as follows: (i) low N and low N (LL), (ii) low N and high-N (LH), (iii) high N and low N (HL), and (iv) high N and high N (HH). Both species had greater shoot and total dry weight after 1 year in the high-N treatment as compared with seedlings grown for 1 year under low-N. For tamarack, these differences were larger and they also exhibited a positive effect of fertilization on net assimilation and water use efficiency. Only black spruce exhibited a positive growth response following the move to higher N fertilization in the second year (LL versus LH), whereas only tamarack exhibited a negative growth response following the move to lower N fertilization (HH versus HL). Still, tamarack had greater total biomass at the end of 2 years than did black spruce, irrespective of fertilizer treatment. Both species had greater total biomass in the HL treatment than in the LH treatment. Tamarack seems able to take advantage of favorable nutrient conditions, but it also experiences more dramatic growth declines under poor or deteriorating conditions. While black spruce grows more slowly than tamarack, it is somewhat buffered from declines in growth under poor or deteriorating conditions. Each species appears to be adapted in its own way to the edaphic heterogeneity that exists in natural boreal peatlands.

Increasing the productivity of soybeans in dry land can be done by designing a package of fertilizer technology based on biological materials using indigenous endomycorrhiza and Rhizobium. The application of indigenous endomycorrhizal biofertilizer combined with Rhizobium is expected to be able to improve nitrogen and phosporus uptake so as to increase the productivity of soybeans in dry land. The experiment used two-factor factorial randomized block design. The first factor was dose of endomycorrhizal spores of Glomus that consisted of four levels, namely, treatment without endomycorrhiza inoculation, dose of 50endomycorrhizal spores, dose of 100 endomycorrhizal spores, and dose of 150 endomycorrhizal spores. The second factor was inoculation of Rhizobium inoculum that consisted of two levels, namely, treatment without Rhizobium inoculation and Rhizobium inoculation. The results showed that combination of 50 endomycorrhizal spores with Rhizobium inoculation gave the best effect on the number of effective root nodules per plant, endomycorrhizal infection per plant, nutrient uptake by plant, number of pods per plant, number of seeds per plant, and oven-dry weight of seeds per plant.

Abstract Insecticides are used widely to control insect pests affecting cowpea and their residues are often deposited in the soil. This may impact the physico-chemical characteristics of the soil and the plant health. This study was designed to investigate the growth response of cowpea treated with lambda-cyhalothrin and dimethoate and the insecticides influence on the physico-chemical characteristics of the soil. Three cowpea seeds were planted per polyethylene bag containing top soil, and later thinned to two plants. The insecticides were assayed singly or combined. The insecticides were applied at the pre-flowering (30th day), flowering (50th day) and at podding (70th day) stages of cowpea growth. The physico-chemical parameters of treated soils were assayed. Treated soils with lambdacyhalothrin and dimethoate and the control were slightly acidic with pH varying from 5.78 to 6.55. Soil organic matter and soil nutrients such as nitrogen, phosphorous, potassium and sodium had lowest values in untreated soil; they had highest values in soil treated with combined insecticides. Lambda-cyhalothrin and dimethoate treatments elicited diverse response from the cowpea plant. Generally, there were slight increase in the vegetative parameters, yield and pod dimensions of treated plants when compared with the control. These insecticides also increased the root nodules, root length and dry weight of cowpea at different concentrations. The combination of these insecticides had positive effect on cowpea without adverse influence on the yield and as well as the soil physicochemical properties.

In specific plant organs, namely the root nodules of alfalfa, fixed nitrogen (ammonia) produced by the symbiotic partner Sinorhizobium meliloti supports the growth of the host plant in nitrogen-depleted environment. Here, we report that a derivative of S. meliloti carrying a mutation in the chromosomal ntrR gene induced nodules with enhanced nitrogen fixation capacity, resulting in an increased dry weight and nitrogen content of alfalfa. The efficient nitrogen fixation is a result of the higher expression level of the nifH gene, encoding one of the subunits of the nitrogenase enzyme, and nifA, the transcriptional regulator of the nif operon. The ntrR gene, controlled negatively by its own product and positively by the symbiotic regulator syrM, is expressed in the same zone of nodules as the nif genes. As a result of the nitrogen-tolerant phenotype of the strain, the beneficial effect of the mutation on efficiency is not abolished in the presence of the exogenous nitrogen source. The ntrR mutant is highly competitive in nodule occupancy compared with the wild-type strain. Sequence analysis of the mutant region revealed a new cluster of genes, termed the “ntrPR operon,” which is highly homologous to a group of vap-related genes of various pathogenic bacteria that are presumably implicated in bacterium-host interactions. On the basis of its favorable properties, the strain is a good candidate for future agricultural utilization.

One of the ways to increase the competitive survivability of rhizobial biofertilizers and thus achieve better plant growth under such conditions is by modifying the rhizospheric environment or community by addition of nonrhizobial nodule-associated bacteria (NAB) that cause better nodulation and plant growth when coinoculated with rhizobia. A study was performed to investigate the most commonly associated nodule-associated bacteria and the rhizospheric microorganisms associated with theFenugreek(Trigonella foenum-graecum) plant. Isolation of nonrhizobial isolates from root nodules ofFenugreekwas carried out along with the rhizospheric isolates. About 64.7% isolates obtained fromFenugreeknodules were gram-negative coccobacilli, 29.41% were gram-positive bacilli, and all rhizospheric isolates except one were gram-positive bacilli. All the isolates were characterized for their plant growth promoting (PGP) activities. Two of the NAB isolates M2N2c and B1N2b (Exiguobacterium sp.) showed maximum positive PGP features. Those NAB isolates when coinoculated with rhizobial strain—S. meliloti, showed plant growth promotion with respect to increase in plant’s root and shoot length, chlorophyll content, nodulation efficiency, and nodule dry weight.

In the present study the effects of Rhizobium inoculation and lime application on the mineral composition (N, P, K, Ca, Mg, Fe, Mn, Cu, Zn, B) of red clover (Trifolium pratense L.), in very acid soil were evaluated. Inoculation with Rhizobium leguminosarum bv. trifolii significantly increased shoot dry weight (SDW) of red clover plants (three times greater), as well as N, Mg, Fe, Mn and Cu contents in plants compared to the control. Application of lime and Rhizobium together, depending on the lime rate (3, 6 or 9 t ha-1 of lime) and the cut, increased SDW significantly, but decreased the contents of N, P, K, Mg, Mn, Zn and B in plants. Regardless of the changes, in all treatments in both cuts, contents of N, K, Ca, Mg, Mn and Zn in plants were among sufficiency levels (Mg content was elevated in the second cut), while Fe content was mainly high, as well as Cu (in the second cut). Contents of P and B in plants were somewhat lower than sufficiency levels, but above critical level. Therefore, red clover can be grown with satisfactory yield and mineral composition in acid soil with Rhizobium inoculation only, but the application of P and B fertilization is desirable.

Limestone mining activities are damaging soil and enviroment. Revegetation becomes an obligation on every mining sites. Paraserianthes falcataria is one of many species that suitable to be planted in revegetation site. Adding compost and NPK fertilizer can improve soil’s condition. This research objective is to analyze the effect of compost and NPK fertilizer on Paraserianthes falcataria seedlings growth and the exact appropriate dosage for limestone mining’s soil condition improvement. The design used in this research is completely randomized design with two factors. The result shows that addtion of compost on tailing media doesn’t give major effect or statistically not significant on seedling growth of height, diameter, the amount of root nodules, and shoot-root ratio, but statistically significant on wet and dry weight of the seedlings. NPK fertilizer addition on tailing media is statistically significant on the seedling growth of diameter, wet weight, and shoot-root ratio, but not significant different on height, dry weight, and the amount of root nodules. Interaction between compost and NPK fertilizer on media gives effect only at 95% of confidence level. K1N5 sample (with 100 gram composts and 5 gram of NPK fertilizer) gives the best respond on seedling’s growth. Very high levels of Ca in the soil medium will be toxic to the Paraserianthes Falcataria plant.Keywords: Compost, limestone mining, NPK fertilizer, Paraserianthes falcataria
