“…The results of two way ANOVA show that for nutrients like lycopene, pectin, protein, vitamin C, reducing sugar and TSS, the F calculated values are higher than corresponding F tabulated value corresponding to 5 % significance, which rejects the hypothesis that the varying treatments in terms of Jatropha cake as well as treatment related to age of transplant do not result in change in nutrient content. (Mbagwu and Ekwealor, 1990) as well as presence of macro and trace elements. Chaturvedi et al (2009) also found increase in nutritional quality of tomato fruit using organic residue like tobacco waste.…”

The present study focused on utilization of the de-oiled Jatropha cake, a bio-waste from the bio diesel extraction process, as organic fertilizer. Tomato crop was subjected to different treatments comprising varying composition of the Jatropha cake fertilizer, applied at varying age of plant life-cycle. The impact on yield, morphological and nutritional parameters was studied. Results revealed that an optimal (2-3 % by weight) dose applied on the soil at the time of onset of flowering (around 45 days), significantly enhanced the yield along with improvements in morphological parameters. There were significant improvements in key nutrients viz. protein, vitamin C and reducing sugars. High value of key nutrients like TSS (total soluble solid), vitamin C, proteins, reducing sugar and tomato fruit yield were obtained with soil + 3% cake mixed in 60 day transplant.These results indicate that composted de-oiled Jatropha cake has tremendous potential of being utilized in a cost effective way as tailored organic fertilizer, as a replacement of chemical fertilizers.

“…These favourable conditions increased the nutrient availability and water holding capacity of the soil resulting in enhanced growth and yield [21]. Besides, organic manures have been found to improve soil physical and chemical properties, increase soil pH by their liming potential and provide trace elements which are usually deficient in continuously cropped soils [22].…”

ABSTRACT. Wastes from brewery, industrial coffee roasting and fiberboard furniture were investigated.Thermogravimetric experiments were carried out with different types of temperature programs. Three models were proposed describing equally well the behavior of the samples. One of the models consisted of three partial reactions with distributed activation energies (DAEM). In this case 12 parameters were sufficient to describe the behavior of a sample in the whole range of observations. The other two models were mathematically simpler, but contained higher numbers of adjustable parameters. The reliability of the models was tested in three ways: (i) the models provided good fit for all experiments; (ii) the evaluation of a narrower subset of the experiments resulted in approximately the same parameters as the evaluation of the whole series of experiments; (iii) the models allowed accurate extrapolations to higher heating rates.
