A field trial was conducted with twelve treatments to test the effectiveness of poultry - carbonaceous wastes compost on the soil properties, growth and yield attributes of sunflower (Var - CO1). Application of compost improved the soil fertility by adding humus and nutrients. Compost along with 100% (60: 45: 45 kg NPK ha-1) and 75% (45: 33: 33kg NPK ha-1) recommended NPK increased the growth and yield of sunflower. Among the composts (Poultry droppings and coir pith, poultry droppings and paddy straw, poultry droppings and coir pith with rock phosphate), the coir pith, rock phosphate mixed poultry compost performed well. The coir pith and rock phosphate added poultry compost along with recommended levels of NPK recorded higher yield which was at par with the results of coir pith mixed poultry compost along with 75 per cent levels of recommended N, P and K. Compost application improved the crop yield, soil fertility status and saved 25 per cent of fertilizer.Keywords

An incubation experiment was conducted to assess the storability of poultry droppings compost for effective utilization and field application. In general, the nutrient content of the compost will vary depending upon the quantity and nutrient content of the manure, age of the compost and the method of storage. In our present study, we found that the storage of poultry droppings under normal condition did not influence the pH of the compost in the first 30 days but a slight reduction in pH (0.1 to 0.2) was observed between 30th day and 45th day. The Electrical Conductivity (EC) of the stored compost was increased but the level of increase was not exceeded 0.02 dS m-1. A slight increase in total nitrogen content was recorded during storage of poultry compost and this might be due to moisture loss and reduction in volume. A slight decrease in total phosphorus and total potassium was also recorded in the stored compost during 75th and 90th day of storage. The microbial population was high between 30th and 45th day of storage. Compost contained a relatively large amount of micro-organisms associated to organic nitrogen mineralization which might have altered the chemical properties. There was no much variation in the nutrient status of the compost during first 45 days of storage and hence the poultry compost can be applied to land within 45 days after its maturity to derive maximum benefits.Keywords

A study was conducted to identify suitable fast growing trees under wasteland condition for carbon sequestration. Accordingly, five fast growing trees namely Tectona grandis Linn., Gmelina arborea Roxb., Dalbergia sissoo Roxb., Bambusa vulgaris var. vulgaris and Swietenia macrophylla king were selected for field study under wasteland condition. The performance of these trees was assessed with biometrical traits (height, basal diameter) and eco-physiological traits (transpiration, photosynthesis, intercellular CO2 concentration and stomatal conductance). Among the five species, Dalbergia sissoo exhibited highest growth, productivity and also superior in ecophysiological traits suits for carbon sequestration. The tree species, Bambusa vulgaris var. vulgaris performed well next to Dalbergia sissoo interms of biometric, productivity and eco-physiological parameters. The lowest biometric and productivity was observed in Gmelina arborea. The tree species, Dalbergia sissoo and Bambusa vulgaris var. vulgaris are highly suitable for afforestation in wastelands to attain carbon sequestration benefits.Keywords

A field experiment was conducted to assess the growth and carbon sequestration potential of five fast growing trees namely Tectona grandis, Gmelina arborea, Dalbergia sissoo, Bambusa vulgaris var. vulgaris and Swietenia macrophylla. The saplings of these five species were planted and assessed for biometric, biomass production and carbon accumulation potential. Among the five tree species, Dalbergia sissoo and Bambusa vulgaris var. vulgaris were found to be superior interms of maximum height, basal diameter, biomass and biomass carbon. Gmelina arborea exhibited low height, basal diameter, biomass and biomass carbon. The per cent contribution of biomass carbon was higher in the stems of all the species followed by ischolar_main, branches and leaves. The field study inferred that, Dalbergia sissoo and Bambusa vulgaris var. vulgaris performed well with higher biomass and biomass carbon productivity under dry land condition and hence these two species can be promoted for afforestation / reforestation of the wastelands in Tamil Nadu under protected irrigation conditions.Keywords
