JANSBiomethanated distillery spentwash and pressmud biocompost as sources of plant nutrients for groundnut (Arachis hypogaea L.) M. Selvamurugan*, P. Doraisamy and M.

E-mail: muruganens@gmail.com Received:June 23, 2013; Revised received:August 1, 2013; Accepted:August 5, 2013 Abstract: A field experiment was conducted to study the impact of biomethanated distillery spentwash and pressmud biocompost in various proportions with inorganic fertilizers on yield attributes, yield, oil and protein content of groundnut at Research and Development Farm of M/s. Bhavani Distilleries and Chemicals Ltd., T.Pudur, Thimiri, Tamil Nadu. Results of the field experiment revealed that yield and yield attributes viz., number of matured pods, 100 kernel weight and shelling percentage of groundnut were improved by the application of biomethanated distillery spentwash and pressmud biocompost compared to recommended NPK as chemical fertilizers. One-time presown application of BDS @ 100 m 3 ha -1 along with recommended NP in groundnut registered higher pod, grain and haulm yield of 1774, 1272 and 4668 kg ha -1 , respectively and the increase was to the tune of 35.83, 43.57 and 46.01 per cent, respectively over control. Similar to yield, BDS application increased the protein and oil content of groundnut kernels significantly. The net returns and benefit cost ratio of sugarcane were also as high as Rs.19,612 ha -1 and 1.90 for the treatment that received pre-sown application of BDS @ 100 m 3 ha -1 along with recommended NP as compared to control of Rs.19,612 ha -1 and 1.38, respectively. This concludes that the biomethanated distillery spentwash can be conveniently used as source of plant nutrients for groundnut.

Exploring the Effects of Enriched Urban Compost and Wastes on Growth and Yield Parameters in Maize (Zea mays L.)

“…The evident impact of treatments on both elevated and diminished growth parameters is distinctly manifested in the yield and yield parameters of maize. These findings align with the results reported by Selvamurugan et al [9] and Rangaraj et al [10]. Sushil Kumar [11] and Terman et al [12] also reported an enhancement in the yield component of wheat and maize with the application of urban compost and sewage sludge.…”

Recycling of sugarcane industries byproducts for preparation of enriched pressmud compost and its influence on growth and yield of rice (Oryza sativa L.)

“…As the pressmud and distillery effluents contain plant nutrients, these could be converted into nutrient-rich organic manure. Conversion of waste products into rich organic manures not only solves the problems of disposal and pollution, but also replenishes the soils and reduces the fertilizer cost (Selvamurugan et al 2013). Although substantial work has been done on the utilization of raw pressmud in rice cultivation, the effect due to composting and enrichment of pressmud on nutrient availability, growth, yield parameters, yield and efficiency parameters of rice is very much limited.…”
