For agriculture, the most important is the soil’s function as a base and medium for plant growth. The soil health and soil condition are important for plant growth. And the management of soil organic matter is an important part in case of managing soil health and maintaining soil conditions. The experiment was carried out in the field lab (Net Hous...

Tea is grown in Bangladesh under marginal climatic and soil conditions. Its production is greatly influenced by many physical, chemical, biological and natural factors. The increasing land use intensity without adequate and balanced use of chemical fertilizers and with little or no use of organic manure has caused severe fertility deterioration of...

The experiment was laid to fit a completely randomized design (CRD) with seven treatments...

A pot experiment was conducted to investigate the effect of coconut peat on growth and yield response of Ipomoea aquatica for Pirojpur soil series during the period of 24th May to 25th June, 2017. The experiment was laid to fit a completely randomized design (CRD) with five treatments [control (T0), 1000 kg coconut peat ha−1 (T1), 1500 kg coconut p...

This study deals with hydro-chemical attributes of surface and groundwater from Khulna District in comparison with standard values for irrigation, industrial uses and drinking purposes. In ground water, pH ranged from 7.02 to 7.43, EC from 0.5 to 5.1 dS m-1 , available Nitrogen from 0 to 69.75 mg l-1 , PO4 3-from 0.34 to 1.26 ppm, K + from 3.35 to...

Application of different types of feeds, fertilisers or food based nutrients in ponds results in the accumulation of high levels nitrogen, phosphorous and organic carbon in water and bottom soil. Farmers can use pond water as an irrigation source while soil as a fertility source of agriculture. study was conducted at Sahas days (from April to May,...

A pot experiment was conducted to investigate the effect of vermicompost and chemical fertiliser on the growth of yield and nutrient content of Ipomoea aquatic and Basella alba during the period of 14th May to 13th July, 2013. The experiment was laid to fit a completely randomized design (CRD) with three treatments [control (T0), vermicompost (T1)...

A pot experiment was conducted to investigate the effect of composted and powdered bones meal on the growth and yield of Amaranthus cruentus on Pirojpur soil series during the period of 25th March to 15th May, 2017. The experiment was laid to fit a completely randomized design (CRD) with seven treatments [control (T0), 2 g chicken bone powder/pot (...
