Paper ID- AMA-19-08-2023-12525

Present study was conduct in purposively selected Narmadapuram (Hoshangabad) district of Madhya Pradesh. Respondents were selected by proportionate method of sampling. Thus the total sample size was 198. Result depicted that out of the total 198 respondents majority 51.51 per cent respondents were performing their role in the medium categories followed by 26.76 per cent were in the low and only 21.71 per cent were performing their Role in high category. During Role performances the major constraint are found is respondents were faced lack of sufficient fund to carry out the work (79.29%) and the major suggestion 81.81 % respondents suggested that essential satisfactory funds should be provided by government.

Evolution of Feronia lemonia genotypes for growth, morphological, yield and quality traits under rainfed semi-arid tracts of western India

Paper ID- AMA-19-08-2023-12523

Wood apple botanically known as Feronia limonia, is important underutilized fruit species. This species have tremendous nutritional and medicinal as well as having huge fruit processing value but it considered as a neglected crop in India. Hence considering its drought hardy nature and climate resilient feature as well as wide adoptability from tropic to subtropics condition the elite germplams are collected from different part of Indian and established as field gene bank in years 2003-04. The evolution of these germplasm under field condition was conducted in years of 2019-20 for their qualitative as well quantatives characters and as well as its nutritional quality of fruits. During this studies also evaluated its suitable flowering and proper maturity indices of fruits. During the whole plant evolution studies among the genotypes, CHESWA-4, CHESWA-6 and CHESWA-10 were found superior in term of yield, quality and nutritional characters. In further observation, it was found that genotypes CHESWA-4 and CHESWA-6 were also found suitable for value addition product like pickles, jam, jelly, fruit powder etc. During the studies it observed that all the genotypes of wood apple exhibited considerable variability for morphological, qualitative and quantative traits.

Diverse inbred lines with better fruit traits improves earliness and yield traits in eggplant (Solanum melongena L.) in Malabar Coast of India

Paper ID- AMA-19-08-2023-12522

Despite the large variability in brinjal germplasm for several growth, fruit traits, bioactive compounds and mineral nutrients in India, low productivity with late fruit harvesting remains the major hurdle in brinjal cultivation. The best way to utilize the heterosis in crop is to generate F1 hybrids with maximum heterozygosity, which leads to the identification and selection of hybrid vigour. The maximum standard heterosis for yield per plant was observed in the cross L5 × T3 (25.30%, Raidurg Local × Pusa Purple Cluster) followed by L2 × T1 (23.35%, IC-433678 × IC-89986), L2× T3 (23.26 %, IC-433678 × Pusa Purple Cluster), L1 × T3 (9.77%, IC-345271 × Pusa Purple Cluster) and L4 × T3 (7.44%, Tiptur Local × Pusa Purple Cluster). The hybrid L5× T3 (Raidurg Local × Pusa Purple Cluster) also exhibited high significant standard heterosis for long styled flowers (37.16%), number of fruits per plant (26.13%), fruit weight (18.68%) as well as earliness traits like days to first harvest (-16.75%) and days to last harvest (-26.87%). The hybrid L2 × T3 (IC-433678 × Pusa Purple Cluster) showed significant standard heterosis for days to first flower (-9.15%), long styled flowers (31.04%), number of length of fruit (18.57%) and fruits per plant (4.21%). Therefore, these hybrids could be identified and released for multilocational trials to the growers to fetch early price and higher yield in brinjal with consumer specific preferences.

Pathogenic variability and infection stategy of Exserhilum turcicum of maize in Meghalaya

Paper ID- AMA-19-08-2023-12521

Northern leaf blight is a lethal foliar disease of maize caused by the fungus Exserohilum turcicum. The aim of this study was to elucidate the pathogenic variability and Severity assessment of the fungus in maize. For pathogenic variability, spore suspensions of fourteen E. turcicum isolates of Meghalaya were inoculated in maize (Variety: Yellow local) at 3-4 leaf stages by means of an atomizer. Results showed that the maximum per cent disease intensity (42.23), virulence index (9.753), lesion length (9.31 x 0.74) and shortest incubation period (4.33 days) was observed in isolate RBEt 02 from Umsning, District Ri- Bhoi, followed by EJEt 03 from Saipong, District East Jaintia hills. The isolate EKEt 02 from Mawrynkhneng, district East Khasi hills showed minimum PDI (21.02), virulence index (2.744) and longest incubation period of 7.66 days. The virulent i.e RBEt 02 was further studied for the infection strategy. The leaves of inoculated plants and un-innoculated (control) were used for the study. Samples were prepared according to standard microscopy procedures and analysed using light microscopy as well as scanning electron microscopy (SEM). Conidia size was observed in the range of 13.2 and 134 μm length. The appressoria exhibited widths of 15-23 μm. Notably, the penetration of the leaf's epidermis occurred directly and specifically at the points where the epidermal cell walls met. Interestingly, penetration was not observed to occur through the stomata (tiny openings on leaf surfaces) or leaf trichomes (fine hair-like structures), even when in close proximity to these structure. The present study provide information about the virulence of Ri-bhoi district isolate as well as its infection strategy.

Delineation of Spatial Variability of Soil Fertility through Digital Soil Maps: A case study of Central Plain Zone of North-West India

Paper ID- AMA-17-08-2023-12517

Digital maps are powerful tools that allow for the visualization and analysis of this variability, providing valuable insights into the distribution of features across space. Sustainable farming practices begin with focusing on smaller areas with better soil than larger ones. No single concept can account for the wide range in soil conditions. The current investigation was carried out at a Krishi Vigyan Kendra(KVK), Kapurthala, an agriculture extension centre of Punjab Agricultural University, Ludhiana, where 15 ha of farmland was divided into four blocks in order to map the spatial variation in soil properties such as soil organic carbon, electrical conductivity (EC), pH, and available phosphorus (P), potassium (K), zinc (Zn), iron (Fe), manganese (Mn), copper (Cu) (mg kg-1), and SOC stocks using geo-statistics. To account for spatial soil variance, digital soil mapping (DSM) was developed following the creation of the base maps using QGIS. Using a standardized technique and GPS instrument, a total of 69 soil samples were collected from different locations in blocks A, B, C, and D, at various soil depths (0-15 cm, 15-30 cm, and 30-60 cm). The surface soil pH in KVK was found to be close to neutral (7.06), while the electrical conductivity (EC) and soil organic carbon (SOC) ranged from 0.7 to 0.21 m mhos cm-1 and 1.95 to 3.98 g kg-1, respectively. For different crops, it was observed that a 25% higher dose of fertilizers than the recommended amount was necessary. In specific quantities, the average phosphorus content in blocks A, B, C, and D was 10.15 kg ha-1, 9.27 kg ha-1, 8.99 kg ha-1, and 9.35 kg ha-1, respectively. Similarly, the average potassium content in the same blocks was 112.4 kg ha-1, 103.3 kg ha-1, 102.5 kg ha-1, and 107.4 kg ha-1. These results indicate deficiencies in phosphorus and potassium levels and suggest the application of appropriate fertilizers to address the nutrient imbalances in the soil. The values for DTPA-Fe, Mn, and Cu in the surface soils of each of the four blocks (A, B, C, and D) were 20.12, 13.92, 6.88, and 4.86; 7.31, 6.08, 15.10, and 15.30; 1.23, 0.75, 0.54, and 0.64 mg kg-1. The DTPA-Zn content of the topsoil in Block A was 7.21 mg kg-1, but in Block C it was only 1.41 mg kg-1. No micronutrients were needed in any KVK block. Block A has the largest C stock (17.04 Mg ha-1) while block C had the lowest (13.22 Mg ha-1). The KVK as a whole had average bulk densities. Soil quality can be enhanced through the use of organic amendments such as green manuring, farm yard manuring, etc. These maps support land-use planning, precision agriculture, and monitoring soil health over time to make informed decisions for sustainable land management practices.
