Organic agriculture is a sustainable and environment friendly production system that offers a wide range of economic, environmental, social and cultural benefits. In the wake of the resources constraints for external farm inputs faced by farmers in developing countries, sustainable agriculture that relies on renewable local or farm resources presents desirable options for enhancing agricultural productivity. The present study was focused on the influence of organic manures such as panchagavya, micro humic acid and farm yard manure (FYM) on the germination and biometric parameters of cluster bean (Cyamopsis tetragonoloba (L.) Taub). The panchagavya soil treatment recorded best germination on 7 th and 21 st treatment on 14 th and 28 th DAS. The root length on 60 90 th day root volume on 60 th day, number of leaves on 60 fresh weight on 60 and 90 th day were improved by to control. The panchagavya soil treatment improved the root length on 30 volume on 30 th day, fresh weight on 30 th day comparison to other treatments. The panchagavya leaf and soil treatment improved number of leaves on 30 th day. The dry weight on 30 panchagavya soil treatment and panchagavya leaf treatment. The FYM improved root length, number of leaves, root volume and dry weight on 90 study that the treatment containing panchagavya (or) biofertilizer (could be an ideal and suitable potting mixture for better seedling and crop production in cluster bean
Organics must form an indispensable component of the manurial schedule for any crop. The present study was designed to study the effect of bio (BD) compost on biochemical parameters of soya bean plants on and 75 th day after sowing. The protein content was more in T of BD compost) on 30 th , 45 th , 60 th and 75 found to be maximum in T1 (3.5 kg of BD compost) on day. The chlorophyll 'a', 'b' and 'total' chlorophyll were highest in T BD compost) on 30 th , 45 th , 60 th and 75 content of the harvested seeds were significantly increased in T 75 th day. The biodynamic compost helps in improvement of crop quality and reduces environmental pollution. The study shows that utilization of biodynamic compost is beneficial for legumes to improve the quality of from the plants.
Article InformationHeavy metals that have been associated only with chemists have now become a concern of environmentalist also. They impact the ecosystems when released into water bodies or soil by various human activities resulting in the environmental pollution. High concentration of Cr (VI) is harmful to animal and human health. The hexavalent chromium exists in aquatic media as water soluble complex anions and persist. These are concentrated in industrial waste water especially from the tannery industries and release of effluents from industries adversely affects the environment. The removal of heavy metals from aqueous solutions is carried out by different physical, chemical and biological methods. Now a days, use of plants waste products such as: barks, manures or lignocellulosic materials, for the removal of heavy metals from polluted water are becoming of more concern. In the present study, low-cost and easily available material such as plant barks for the removal of chromium VI from its aqueous solution was investigated. Bark powders of plants namely, Pongamia glabra, Tamarindus indicus, Tesphesia populnea, and Mangifera indica obtained from nearby saw mills, were used as adsorbent for the removal of Cr (VI) from aqueous solutions in excess of maximum permissible limits. Adsorption for chromium (VI) was found to be highly dose dependent compared to the other parameters observed with almost 100 % efficiency at pH 2, contact time of 2h at room temperature with 3 g l -1 bark dosage. The adsorption capacities of all the plant barks for chromium (VI) was found to be comparable to other commercial adsorbents currently employed for the removal of heavy metals from aqueous wastes. The results have demonstrated the immense potential of plants bark powder as an alternative adsorbent for removal of Cr(VI) ions from polluted water.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
