An experiment with eleven multipurpose tree species was conducted on red sandy loam soils of Agroforestry block in Acharya NG Ranga Agricultural University, Rajendranagar campus. Evaluation of tree species nine years after plantation revealed that Dalbergia sissoo, Leucaena leucocephala, Acacia auriculiformis and Eucalyptus camaldulensis were fast growing and suitable to Southern Telengana Zone of Andhra Pradesh which are dominated with red sandy loam soil. Studies on biomass production (Small and log wood) of eleven multipurpose tree species revealed that Dalbergia sissoo (214.6 t ha-1 ) recorded maximum biomass followed by Leucaena leucocephala (187.8 t ha-1) and Acacia auriculiformis (162.4 t ha-1 ). Maximum Mean Annual Biomass Production (MABP) recorded was also more; for Dalbergia sissoo (23.8 t ha-1) followed by Leucaena leucocephala (20.9 t ha-1) and Acacia auriculiformis (18.0 t ha-1 ). Biomass yield component studies such as foliage yield at ninth year after planting revealed that maximum foliage production on oven dry weight basis was recorded by Leucaena leucocephala (16.8 t ha-1) followed by Acacia auriculiformis (12.0 t ha-1 ) and Eucalyptus camaldulensis (9.9 t ha-1 ). Cost benefit analysis of the study showed that for every rupee spent on cultivation of these tree species, highest return was obtained from Dalbergia sissoo (4.4) followed by Leucaena leucocephala (4.0), Acacia auriculiformis (3.1) and Eucalyptus (2.9).- Stabilizing Crop Productivity Returns and Soil Improvement by Agroforestry Practices Under Marginal Lands in Semi-Arid Tropics of Telangana State, India

Different agroforestry trials conducted in Agroforestry Research blocks, Professor Jayashankar Telangana State Agricultural University, Hyderabad has showed higher economic gain in marginal lands. Sunflower grown when inter cropped in Hardwickia binata after stylo recorded higher seed yield (342 kg ha-1) than grown after fallow in Hardwickia binata (248 kg ha-1). The net returns from tree and crop were considerably higher when sunflower grown as inter crop in Hardwickia binata Rs. 6593 ha-1. The Faidherbia albida (13 years age old) trial revealed that seed yield of maize+soybean when grown as inter crop was higher (2.94 t ha-1) when compared to sole cropped maize without trees (1.7 t ha-1). Due to shade effect of tamarind, after 8 years the same system was converted to horti-horti system for better land utilization by planting economic demand plants such as henna. The higher fresh biomass production of henna (640 kg ha-1) recorded in double row planting when compared to single row. The soil productivity and fertility was improved in degraded marginal lands by different agroforestry practices. Pertaining to soil improvement over initial in different agroforestry practices the influence of different land use systems on soil properties and nutrient status revealed that bulk density reduced in surface and sub-surface soil in all tree based systems as compared to fallow (1.65 and 1.68 mg m-3) and agricultural lands. The water holding capacity and infiltration rate was maximum in agri-horti system 30.0 and 30.0 per cent at 0-15 and 15-30 cm depth, respectively. Nutrient status and organic carbon was more in soils with tree plantation. Soil enrichment found in marginal lands in different agroforestry practices such as Melia azedarach based agri-silvi system, the conjoint use of 75% RDN+25% N poultry manure showed significant effect on OC (0.59%) and available NPK (150.0, 24.95, 210.0 kg ha-1) followed by 100% RDF (0.55% and 147.0,24.00,216.0 kg ha-1). In case of Melia dubia based silvi-pasture system, the OC and available N and P significantly affected by type of fodders and nutrient management over farmers practice i.e. FYM 10 t ha-1. But there is no significant effect by interactions. The highest OC content recorded in fodder maize (0.52%) than sorghum (0.46%). In case of available N and P the significant effect found with fodder sorghum (152.0 and 51.00 kg ha-1) than maize (109 and 22.42 kg ha-1).Keywords
