Residual effect of composted kitchen waste and poultry manure soil amendments on yield and concentrations of copper, iron, manganese and zinc in leaf tissue of jute mallow (corchorus olitorius linn)

Abstract: Source of organic amendment for the production of vegetable crops is of prime importance for safe soil to prevent contamination of the food chain. This study assessed residual effects of composted kitchen waste (KW) and poultry manure (PM) soil amendments on growth, leaf dry weight (LDW), accumulation and transfer of four heavy metals: copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) in leaf tissue of Jute mallow (Corchorus olitorius) under field condition. The main treatments (KW and PM) and sub-treatments amendment rates (0, 5, 10, 15 t ha-1) were replicated three times in a Randomized Complete Block Design (RCBD). At six weeks after sowing, plants were harvested and leaf tissue was analyzed. Data collected were subjected to analysis of variance (ANOVA) and result showed that plant amended with PM gave significantly (p Cu (0.77-1.37) > Mn (0.24-0.40) > Fe (0.026-0.039). The TF decreased with increased amendment rate despite increased total concentration of metals in the soil. Poultry manure with higher metal binding effect can immobilize metals better than KW.

Thermal Decomposition Behavior Study of Two Agricultural Solid Wastes for Production of Bio-Fuels by Pyrolysis Technology

Abstract: In this study pyrolysis kinetics of jute stick (white jute: Corchorus capsularis; tossa jute: Corchorus olitorius) and tamarind (Tamarindus indica) seed available in Bangladesh have been investigated thermogravimetrically in a nitrogen atmosphere at heating rates of 10 and 60°C/min over a temperature range of 30 to 800°C. The two biomass solid wastes exhibited similar behaviors in that, the weight loss region is shifted to a higher temperature range and the weight loss rate is increased with increasing heating rate. The percentage of total weight loss is higher for jute stick and is lower for tamarind seed. The overall rate equation for the two biomass wastes has been modeled satisfactorily by one simplified equation from which the kinetic parameters of unreacted materials based on the Arrhenius form can be determined. The predicted rate equation compares fairly well with the measured TG and DTG data.

PHYSICOCHEMICAL BASIS FOR RELATIVE SUSCEPTIBILITY OF TWO JUTE MALLOW MORPHOTYPES TO Acraea eponina CRAMER

Abstract: The leaves of Corchorus olitorius L. are rich in antioxidants, fatty acids, minerals, vitamins and mucilaginous polysaccharides and it was reported in a preliminary study that larval Acraea eponina (Cramer) showed preference for C. olitorius morphotype with serrated leaves (NC1) compared to the morphotype with smooth-edged leaves (NC2). The current study was, therefore, carried out to determine physicochemical properties of C. olitorius that mediate preference of A. eponina for NC1. The proximate and mineral analyses of leaves harvested from the two morphotypes were carried out using standard methods of food analysis. Viscosity of mucilage extracted from the leaves of the two morphotypes was also measured using a viscometer. The results of proximate composition showed that NC1 contained higher amount of crude protein (37.47%) which is essential for tissue formation and rapid growth of the immature larvae. The C. olitorius with serrated leaves also had higher levels of ash (12.59%) and moisture (95.66%) compared to NC2. A similar trend was observed in the mineral content with NC1 containing higher levels of manganese (5.15 mg/100g; needed for formation of insect cuticle), iron (15.71 mg/100g), copper (0.79 mg/100g), magnesium (38.98 mg/100g) and chromium (0.62 mg/100g). However, mucilage from the leaves of NC2 was found to be more viscous, a factor that may reduce the desirability of A. eponina for the morphotype. The results showed that NC1 has a superior nutritional quality necessary for growth and development of the larval A. eponina and this is responsible for the preference for this morphotype by foraging larvae.
