AbstractAmendment of soil with biochar has been shown to enhance fertility and increase crop productivity, but the specific influence of biochar on soil workability remains unclear. Select physico-mechanical and chemical properties of clay loam and sandy loam soils were measured after amendment with wood-derived biochar of two particle size ranges (0.5-425 and 425-850 µm) at five dosages ranging from 0.5 to 10% dry weight. Whereas the clay loam soil workability decreased when the finer wood-derived biochar was applied at rates of 6 or 10%, soil fertility was not enhanced. The sandy loam soil, due to Proctor compaction, significantly decreased in bulk density with 6 and 10% wood-derived biochar amendments indicating higher soil resistance to compaction.

Six isolates of Rhizobium were isolated from pea (Pisum sativum) to characterize their cultural properties and observe their effectiveness on host legume. In a laboratory study Rhizobium isolates showed characteristic pattern of reactions in respect of growth rate, colony characteristics and acid/alkali production on different growth media. The effect of inoculations of Rhizobium isolates on nodulation, growth and nitrogen fixation of pea were assessed by a pot experiment on a clay loam soil of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur. Inoculation treatments comprised of Rhizobium isolates R1, R2, R3, R4, R5 and R6. Among the Rhizobium isolates R3 and R5 of pea at 50% flowering stage had significant positive effective on nodulation, growth and nitrogen fixation of pea. There were high positive correlations among the number and dry weight of nodules, N content and uptake by shoot of pea.

SUMMARYOn a clay loam soil, the cultivar Col 148, planted in spring 1987 at 57560 three-budded setts/ha received 0, 75, 100 and 150 kg N/ha and 0, 10, 20 and 30 t/ha fresh sulphitation press mud either separately or in combined applications, at 80% moisture. Separate applications of up to 150 kg N/ha and up to 30 t press mud/ha increased the cane biomass by 24·6% and 13·2%, respectively, whereas combined application increased it up to 38·1% more than in the control. A N concentration of 1·95–2·12% in the blades of leaves 3·6 from the top of the plant from tillering to the grand growth stage was necessary for maximum dry matter production. Sulphitation press mud enhanced uptake and availability of N and P to the crop and reduced soil pH. Application of 10 t press mud/ha saved 75 kg/ha of fertilizer N.

A field experiment was conducted at the field of CAMPUS OF LIVE SCIENCES, Dang having clay loam soil to evaluate effect of integrated management of FYM and urea in cabbage. This experiment was carried out in Randomized Complete Block Design (RCBD) having six treatments with three replications. Golden Ball variety of cabbage was selected for this research as a test crop. The application of FYM and urea shows significant result on the plant height, number of leaves, length of plant, head diameter and biomass yield. The maximum head diameter was observed in treatment 50%FYM +50% UREA (14.31cm).The highest total yield (9.63Mt/ha) and highest economic yield (6.16Mt/ha) was obtained from treatment 50%UREA +50 %FYM which was similar with recommend rate of fertilizer for cabbage. The highest soil pH (6.40), soil moister content (40.46%), the lowest bulk density (1.12g/cm3) was obtained from FYM application. The highest organic matter content (1.46) was also observed from FYM application. The most of the soil properties were enhanced by application of FYM and UREA. Furthermore, FYM played important role in maintaining soil physical property. In addition, this study indicates the possibility of FYM application to reduce nutrient risk by enhancing physio-chemical properties of clay loam soil. This result will helpful for the student and scientists in further research to increase the productivity and for the improvement of soil property.

Beneficial microorganisms play a key role in the availability of ions minerals in the soil and use Randomized Complete Block Desing ( R.C.B.D ). The objective of this paper to the study effect of the of biofertilizer and miniral treatments on availability of NPK for crop corn zea mays L.Two types of biofertilizer are Bacterial Bacillus subtilis and Fungal Trichoderma harianum. Three levels of potassium fertilizer are (2.9533, 0.4000 and 2.9533). A field experiment in fall season of 2018 Has been conducted in silty clay loam soil. The experimental Results indicated that Bacillus and Trichoderma inoculation separately or together Have made a significant effect to increase in the availability of N P K in the soil compare to other treatments. The grain yield is where (2.9533, 0.4000 and 2.9533) of bacterial and fungal bio-fertilizer and potassium fertilizers respectively as compared to the control.
