dc.descriptionDescription: The present field experiment was conducted at the Centre for Organic Agriculture Research and Training Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) during the year 2018-19 in kharif season. The experiment was laid out in Factorial Randomized Block Design with four weed biomass at pre flowering stages i.e. Cassia tora, Sorghum helepense, Mix weed species and Parthenium hysterophorus with three cultures which comprised S-9, PDKV and control without culture. The combinations of twelve treatments were replicated three times.en_US
dc.description.abstractAbstract: The study was aimed to explore the possibility of conversion of different available weed biomass to utilize the embedded nutrients for supplying enriched organic manure for better soil health and crop growth, which will not only improve the yield and quality of the produce but also conserve energy, minimize pollution, save foreign exchange and improve the fertilizer use efficiency and subsequently that will help to revitalize and restore the soil fertility and will revive the microbial activities for sustainable crop production. An experiment on, “Effect of different decomposing culture on quality of compost from weed biomass” was carried out during August to November in year 2018-19 at Centre for Organic Agriculture Research and Training (COART) Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola with twelve treatments as different weed biomass viz., of Cassia tora, Sorghum helepense, Parthenium hysterophorus and some other species of weed replicated thrice in Factorial Randomized Block Design by using different decomposing cultures like S-9 culture, PDKV culture and Dung slurry. The periodical chemical analysis carried during weed composting indicated decrease in pH, total organic carbon, C:N ratio while increase in nutrient content and microbial population with the advancement of composting. Composting samples were collected and analyzed for chemical and biological properties at different stages viz., 30, 60, 90 DAF tanks and at maturity (differed with different treatments). Initially the maximum temperature (47.2 0C) was recorded in Parthenium hysterophorus followed by 45.6 in mix weed, 45.1 0C in Sorghum helepense and 44.8 0C in Cassia tora compost at 3 weeks after filling of compost pits. Further the temperature was steadily decreased towards maturity. Among the three decomposing culture PDKV culture recorded highest temperature followed by S-9 and dung slurry. It was revealed that Sorghum helepense weed biomass indicated statistically higher reduction of about 32.69 kg over initial weight added in compost pit of 60 kg at start of filling of compost pit. However, Cassia tora recorded less reduction in weight of about 29.13 kg. Mix weed recorded reduction in weight of about 31.80 kg and Parthenium hysterophorus recorded reduction in weight of about 31 kg over initial weight of material added in compost pit of 60 kg. Among four weed biomass, the pH was significantly highest in mix weed during composting (7.38 at 30 DAF and 7.92 at DAF respectively). At maturity, EC of mix weed compost was significantly lower than other weed compost. At maturity stage mix weed compost showed significantly maximum reduction (20.58 %) in total organic carbon while the lowest C:N ratio (15.13: 1) was recorded with mix weed compost. Mix weed compost was rich in total N (1.36 %), P (0.65 %) and K (0.59 %) followed by Cassia tora, Parthenium hysterophorus and Sorghum helepense compost. Among the different weed biomass, compost obtained from mix weeds recorded significantly maximum bacterial, fungal and actinomycetes population at maturity.en_US
