Agro-industrial waste improves the nutritional and antioxidant profile of Pleurotus djamor

The effect of agro-industrial wastes (coffee pulp, rice straw, corncobs, and their mixtures) on the biological efficiency, nutritional composition, and antioxidant activity of Pleurotus djamor was evaluated. The biological efficiency was in a range of 8.26–95.95%. Coffee pulp mixed with other residues increases the biological efficiency of the mushroom. The content of protein, crude fat, fiber, carbohydrates, total polyphenols and antioxidant activity DPPH and ABTS were in the range of 21.61–27.09%, 0.77–2.26%, 13.32–19.40%, 41.45–51.06%, 1.74–3.03 mgGAE / g, 0.051–0.091mMTE / g and 0.067–0.133 mMTE / g respectively. An order of abundance was observed for macro-elements of Ca> P > K> Mg> Na and for microelements of Zn> Fe> Cu in the mushroom, similar order to that presented in the formulations where they were cultivated. It was found that the combinations of substrates improve the nutritional parameters of the mushroom, while the mineral content of the fruiting bodies was influenced by the mineral content of the substrate where they grow. The use of these residues allows obtaining a product with great nutritional and nutraceutical value through a simple, low-cost, and sustainable biotechnological process. • Antioxidant activity in P. djamor cultivated in agro-industrial wastes.. • Nutritional composition of P. djamor in different mixtures. • Antioxidants and proteins increased when grown in coffee pulp and corncobs. • A nutritious and nutraceutical product was obtained at low cost. • Contribution to cleaner production of P. djamor in agro-industrial wastes.

Improving Physiological and Yield Traits of Groundnut (Arachis hypogaea L.) by using Various Sources of Organic Wastes and Bio Fertilizers, Rhizobia

Background: Investigations were carried out during Rabi, 2016 and Summer, 2017 at farmer’s field in Kodukkanpalayam village of Cuddalore District, Tamil Nadu to evaluate the direct effects of agro industrial wastes (bagasse ash, pressmud and distillery spentwash), crop residues, farmyard manure with 50% inorganic sources, with and without Rhizobia on various traits of groundnut. There were twelve treatments in randomized block design (RBD) with three replications. Results revealed that the growth and yield components of groundnut viz., plant height, DMP and LAI at flowering stage, number of pods per plant, hundred kernel weight, pod yield and kernel yield were greatly influenced by the treatments. Methods: Combination of Pressmud @ 12.5 t ha-1 + Rhizobia @ 2 kg ha-1 + 50% RDF (T7) recorded the highest and followed by the application of distillery spentwash @ 100 m3 ha-1 + Rhizobia @ 2 kg ha-1 + 50% RDF (T8). Similar trend of results was recorded in summer, 2017 also. This might be due to the increase in the availability of nutrients, which increased the growth and yield attributes of groundnut in both the seasons. Also, use of agro industrial wastes and biofertilizers in any cropping sequence minimize the cost of inorganic fertilizers, thereby act as a boom to farmers by making the waste into wealth and maintain the soil health and fertility. Result: The study revealed the scope of utilization of agro industrial wastes (bagasse ash, pressmud and distillery spentwash), organic sources (crop residues and FYM) and biofertilizer (Rhizobia) in Agriculture.

Effect of agro industrial wastes compost on soil health and onion yields improvements: study at field condition

PurposeIndustries are generating numerous amount and types of organic wastes to the environment. The aim of the present study was to investigate the effects of agro industrial wastes compost on soil physicochemical quality, soil microbial population, growth and yield of onion (Allium cepa L.) under field condition .MethodsThe experiment was conducted in a completely randomized plot design at field condition. Allium cepa L. was grown using five different levels of agro industrial wastes compost, three different levels of inorganic fertilizers and three controls.ResultsCompost amendment improved the soil pH, TOC, TKN, field capacity (FC), permanent wilting point (PWP), and available water content (AWC), cultivable bacterial count and fungi. But no significant effect was found on electrical conductivity (EC), available phosphorus (P) compared to the control. Exchangeable Na, K, Ca, Mg, Fe, Zn, and Cu increased while Pb, Cr, and Mn value showed no significant change with compost application. Field application of compost improved onion shoot numbers, shoot girth, and shoot length. Further, significant shoot weight and bulb weight were also obtained after compost treatment.ConclusionsAfter compost amendment significant improvement in soil fertility and onion yield was obtained. This can be recommended for small scale farmer’s food security improvement and combined with agro industrial wastes management.

Residual effect of agro-industrial wastes on soil properties and Zea mays (L.) nutrition

The residual effect of agro-industrial wastes previously used for potato growing was investigated for soil characteristics and maize nutrition. The soil pH increased and organic matter decreased during maize growth. Nitrogen and K were generally low, but statistically higher almost in waste-applied soils. Soil phosphorus was greatest in the ‘Only Wastes’ and ‘Min.P + Wastes NK’ treatments. N, P, K and Ca decreased significantly in the soil of ‘Only Wastes’ during maize growth, as did the organic matter content. ‘Only wastes’ generally produced a maximum maize growth parameter. Zinc and Mn were low in soils and no pollution risk arose with respect to heavy metals. Nitrogen, K, Zn and Mn of leaves were below adequate levels. Lead and Cr in plants decreased with the chelating effect of increased organic matter. Phosphorus in wastes gave significantly the highest yield, and P in kernel had the effect of increasing some yield parameters in maize.
