International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad (B2), and Shivpuri (V7), Manoharpur (V8), Nwalpura (V9), block in Shahpura (B3). At collection of soil sampling site-, twenty-seven soil samples were collected at different depths of 0-15 cm, 15-30 cm and 30-45 cm. Soil samples were collected randomly from a site using Khurpi and Phawrah and Auger the depth of (a) 0-15cm, (b) 15-30cm, (c) 30-45 cm. Composite soil samples (by the process of conning and quartering method) was collected by Stratified soil sampling. After collecting the soil samples, they were analysed following standard laboratory procedures. brought to the laboratory. Results The results showed in soils from different villages of most of Jaipur district soils, Sandy Loam Texture was discovered at three depths (0-15 cm, 15-30 cm, and 30-45 cm) (Table-2). The percentages of sand, silt, and clay ranged from 60.11 to 72.60 percent, 13.35 to 24.59 percent, and 12.35 to 15.62 percent, respectively. The soil color of soil also noticed in both the Air- dry condition and wet condition. The Soil color was Light Yellowish-Brown (10YR6/4) color to brownish yellow (10YR5/8) (Table-3). The results showed in soils from different villages The maximum bulk density was 1.35 Mg m -3 at 30-45 cm in village Morija (V 2), and the lowest bulk density was 1.22 Mg m -3 at 0-15 cm in village Nwalpura (V 9). with increasing soil depths, the bulk density increases. At depth 30-45 cm in village Morija (V2), the maximum particle density was 2.37 Mg m -3 , while at 0-15 cm in village Shivpuri, the minimum particle density was 2.24 Mg m -3 (V7). Bulk density is lower than particle density. The largest percent pore space was reported at 0-15 cm in village Keshav Nagar (V 1), while the smallest percent pore space was measured at 30-45 cm in village Shivpuri (V 7). The % pore space decreases sharply as depth increases. The maximum water holding capacity was found 60.12 % at 0-15cm in village Nwalpura (V 9 ) and minimum water holding capacity % was found 41.27 % at 30-45 cm in village Morija (V 2 ) (Table-1). These variations were due to clay, silt and organic carbon content and low Water holding capacity in sandy soils due to high sand and less clay content. However, in Village Shivpuri (V7) had the highest specific gravity of 2.56 at 30-45 cm, while village Morija had the lowest specific gravity of 2.33 at 0- 15 cm (V 2). Clay, silt, and organic carbon concentration all played a role, as did low Water holding capacity in sandy soils due to high sand and low clay content. Conclusion The soil of investigated area was sandy loam textured soil. The soil color was light Yellowish-Brown to brownish yellow which signifies a good organic matter. Improve of soil health by using organic manure and bio fertilizers and improve soil physical condition at study area, depth from upper to lower soil layers pore space % decrease because soil compacted, that is not suitable for good soil aeration. Growing Bajara, Mustard, Barley, Wheat, Tomato, Cole crops and Gram crops are suitable at present study area. Resource conservation and rainfed agriculture 596 | Page

Shivay and Manoj Shrivastava ICAR-Indian Agricultural Research Institute, New Delhi 110012, India priyankameena28@gmail.com, manojshrivastava31@gmail.com Worldwide land under organic farming in 2017-18 encompassed more than 69.8 million hectares and India has around 1.78 m ha under organic farming. Trace elements have important role in plant and animal nutrition and their deficiencies and toxicities cause adverse effects on plant growth. There is a need to maintain optimal concentrations of micronutrients in soil and plant to the attainment of optimum economic yields of crops and animal productivity and welfare. A field study has been conducted to investigate the available micronutrients in different aggregates under organic and conventional farming practices. The field experiment was, thus, conducted at the research farm of the Indian Agricultural Research Institute, New Delhi on sandy clay-loam soil starting from Kharif 2006 under the rice-wheat cropping system. The experiment was laid out in a randomized block design with three replications and eight treatments in a set. The treatments consisted of control (T1), farmyard manure (FYM@ 10 t/ha) applied to only rice (T2); FYM @ 10 t/ha applied to only wheat (T3); FYM @ 10 t/ha applied to rice and wheat (T4); Sesbania green manure (SGM) to rice and Leucaena green leaf manuring (LGLM) to wheat (T5); SGM+Blue Green Algae (BGA) and LGLM+Azotobacter to wheat (T6); SGM+FYM to rice and LGLM+FYM to wheat (T7); and SGM+FYM+BGA to rice and LGLM+FYM+Azotobacter to wheat (T8). In this study, the effect of organic amendments was evaluated on physical soil properties i.e., different size aggregates and yield of the respective system by sampling the soil from three depths (0-15, 15-30, and 30-60 cm) for two seasons in rice and wheat (2020-2021 and 2021- 2022). The results were found to be improved in T8 in the case of the yield of rice and wheat. 597 | Page Resource conservation and rainfed agriculture
