However, soil P content was maximum under mentha crop (T4) and lower in guava sole system (T7) at both depths. The available K status of soil was recorded highest when medicinal crops were grown under guava-based intercropping as compared to guava sole. Conclusion From the present investigation it is concluded that he combination of fruit orchard and medicinal crops seems to improve the physical and chemical properties as well as status of macro-nutrients of orchard soil more than guava alone, probably due to more and faster decomposition of litter fall and root biomass of cover crops. Hence, guava based hortimedicinal cropping system can be adopted in large scale to improve soil fertility status. References Bhatnagar, P., Kaul, M.K., and Singh, J., 2007.

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad T4a-37P-1318 Influence of Natural Farming on Soil Properties, Crop Protection and Production of Quality Produce in Sugarcane K.V. Ramana Murthy, Dr M. Bharathalakshmi, Ch. S. Rama Lakshmi, M. Visalakshi, P. Kishore Varma and D. Adilakshmi Regional Agricultural Research Station, Anakapalli-531001, Andhra Pradesh The increased and often indiscriminate use of fertilizers and pesticides immensely harmed biological activity of the soil rendering it almost lifeless in vast areas. Agriculture production has tended to remain either stagnant or is declining despite application of high-cost inputs in large number of agricultural zones. Agriculture production despite troughs due to drought and aberrant weather conditions showed remarkable resilience but the quantum jump in production is conspicuous by its absence. Experts attribute this stagnation to destruction of soil health due to application of fertilizers and pesticides. Hence, this study was formulated to validate the natural farming practices in sugarcane + pulse intercropping for sustained soil and crop productivity in sugarcane. Methodology A field trial was taken up during 2020-21 and 2021-22 at Regional Agricultural Research Station, Anakapalli, Andhra Pradesh in sandy clay loam soils, The pH of the soil was 7.22, EC 0.27 dS m -1 . The soil was low in available nitrogen (188 kg/ha), medium in available phosphorus (72 kg/ha) and high in available potassium (223 kg/ha). The micronutrient availability of zinc was 0.97 ppm, Copper 2.32 ppm, Manganese 14.58 ppm and Iron 10.15 ppm. The treatments were T1-Integrated Crop Management (University recommendation), T2-Natural Farming and Organic Farming and T3-Palekar’s Zero Based Natural Farming (ZBNF) replicated thrice. The test variety was a short duration sugarcane variety 2009 A 252 (Naveen). The weather conditions that prevailed during the growth period of sugarcane during these two years were congenial for the crop growth. A rainfall of1670.5 mm during 2020-21 and 1306. 4 mm during 2021-22 was received with rainy days of 72 and 69 days respectively. The protocol was followed as per gelines for the three systems of cultivation. Results During 2020-21 in plant crop and in 2021-22 in ratoon crop, with respect to the soil physico chemical properties, available phosphorus and potassium, Zinc and Iron were higher in ICM while available nitrogen, Fe and Mn were high with OF & NF.
