Rice husk Biochar: An effective management strategy against Sclerotinia sclerotiorum

Paper ID- AMA-18-07-2022-11538

To observe the effect of rice husk biochar in inhibiting the carpogenic germination of Sclerotinia sclerotiorum, and its role in inducing defence mechanism in tomato plants against the pathogen to minimise the losses caused by Sclerotinia stem rot in tomato. In vitro and glass house experiment were carried out to test the effect of rice husk biochar in combination with bioagents against Sclerotinia sclertiorum. Rice husk biochar at the rate of 1%, 3% and 5% concentration completely inhibited the carpogenic germination of sclerotia. Rice husk biochar @1%+ Trichoderma harzianum @ 10gm Kg-1soil was found to be most effective amongst all the treatments in promoting plant growth and enhancing the production of defence inducing enzymes Phenyl ammonia lyase (PAL), Polyphenol oxidase (PPO), Peroxidase(PO) and Total Phenol Content (TPC) thus consequently reducing the disease severity.

Soil Physical Characteristics And Aggregate Stability Influenced By Different Land Uses In Humid Subtropics of Silt-Loam Soils In East Khasi Hills, Meghalaya

Paper ID- AMA-13-07-2022-11534

Information about the soil physical and structural quality of diverse land-uses (LUS) is essential for the sustainable development, utilization, and protection of natural resource viz. soil in plateau of Meghalaya. In this study, depth wise (0-0.15 m and 0.16-0.30 m) particle size distribution, bulk density (BD), particle density (PD), maximum water holding capacity (MWHC), aggregated (Silt+Clay), structural stability index (St), mean weight diameter (MWD) and geometric mean weight diameter (GMD) were analyzed under Jhum-System, Mixed-Forest, Pine-Forest, Rice-Potato, Rice-Cole Crop, Upland Rice-Monocrop, Lowland Rice-Monocrop, Upland Pineapple-System and Upland Broom-System suited in Upper Shillong, East Khasi Hills, Meghalaya. The results showed alteration in sand, silt, clay, BD, PD, MWHC, AG (Silt+Clay), St, MWD and GMD in relation to diverse land uses (LUS). The Mixed-Forest soils had the lowest BD (1.15 Mg/m3), at surface and highest in Rice-Potato (1.39 Mg/m3). The mean content of PD and MWHC in all types LUS were varies between 2.40-2.75 (Mg/m3) and 45.04-58.37%, respectively whereas highest PD and MWHC was recorded in Jhum-System and upland Broom-System, respectively. The BD of different LUS was increases with depth and MWHC decreases with depth. The ranges of AG (Silt+Clay), MWD, GMD and St were ranging from 67.19-75.98%, 1.08-2.42 (mm), 0.61-1.25 (mm) and 3.81-6.87%, while highest and lowest value were observed in all LUS in surface soil Mixed-Forest and Rice-Cole Crop. On an average in the subsurface soil all soil aggregate parameters were decline in different LUS. Correlation between aggregating elements and aggregate stability parameters with MWD viz. GMD and St were positively correlated with MWD @ 0.01 per cent level (2-tailed) under different LUS in 0-15 cm whereas sand and clay have no correlation with MWD. Relationship between silt, AG (Silt+Clay) with sand had strongly negative correlation, while with St has strongly positive correlation @ 99 per cent confidence level.

Critical analysis of performance of Farmer Producer Organizations (FPOs) in Rayalaseema region of Andhra Pradesh

Paper ID- AMA-12-07-2022-11532

Farmer Producer Organizations enable member farmers to reap the benefits of economies of scale in purchase of inputs, marketing, processing and value addition to their produce. The findings of performance of FPO would help the FPO promoting agencies, NGOs and management of FPO to focus their efforts on further improvement of functioning and services provided by the FPO to its members. The results revealed that, the overall mean performance score related to functioning was good. Among five components related to functioning indicator, the performance of audit system was ranked first followed by performance of members representation group dynamics, infrastructural facilities and governance and management. Whereas the overall mean performance score related to services was average. Among five service components, the performance of technical services was ranked first followed by the performance of input services, financial services, marketing services, processing and value addition.

On Farm Evaluation of Balanced Fertilization on Productivity, Nutrient use Efficiency and Economics of Pre-dominate R-W Cropping System of Jammu Region

Paper ID- AMA-12-07-2022-11530

A field experiment was conducted at 24 locations (four farmers in a village, three villages viz., Kothimorh, Dabber and Chakbana of Bishnah and Shekhupur, Chakmajra and Chakkeema of Arnia in two blocks i.e. Bishnah and Arnia) to evaluate the effect of balanced fertilization on productivity, nutrient use efficiency and economics of Rice-Wheat predominant cropping system of Jammu district of J&K during 2017-18 to 2019-20. The Experiment was laid out in RBD design. Seven fertilizer treatments; Control (0-0-0), N alone (N-0-0), NP (N-P-0), NK (N-0-K), NPK (N-P-K), NPK + Zn (N-P-K-Zn), FP (Farmers Practices) were taken under study and the data revealed that the application of recommended dose of NPK +ZN realized the highest grain yield of rice 2916.14 kg/ha and wheat (2926.29 kg/ha) and productivity in terms of REY 5772.85 kg, system net returns Rs 133188 with B:C ratio of 3.16 in comparison to other treatments. However, the average partial factor productivity was observed in the order of NPK in Rice (97.20, 145.80 and 291.61) and in Wheat (29.26, 58.52 and 117.05 kg grain/kg) along with agronomic use efficiency of 54.86, 82.29 and 164.58 in rice and 15.47, 30.94 and 61.89 kg grain/kg of applied nutrient in wheat. And Nutrient response in rice (26.7 kg grain/kg) and wheat (28.23 kg grain/kg) was also observed in the plots fertilized with recommended dose of NPK+ Zn. Balanced application of N, P and K was found to increase the system productivity and nutrient use efficiency of Rice-Wheat cropping system.

Efficacy of Sulfoxaflor 12 % SC against aphid (Myzus persicae) in Potato

Paper ID- AMA-12-07-2022-11528

A field experiment was carried out at Agricultural Research Station, Kota (Rajasthan) during rabi-2017-18 & 2018-19 to evaluated efficacy of sulfoxaflor 12% SC against aphids viz., aphids (Myzus persicae). The various doses of sulfoxaflor 12% SC i.e. 175, 200, 225 and 450 ml/ ha (450 ml/ha only for phytotoxicity test) along with standard check thiamethoxam 25 % WG at 100 g/ha were evaluated against aphids of potato. The minimum population (0.95 & 0.75 and 1.46 & 0.96 aphids/plant) was recorded in sulfoxaflor 12% SC @ 225 ml/ha after 10 days of spray during 2017-18 & 2018-19, respectively and was statistically significant in compare to other treatments. It was followed by sulfoxaflor 12% SC @ 200 ml/ha and thiamethoxam 25% WG @ 100 g/ha. The highest mean tuber yield of 10.69 t/ha was recorded in sulfoxaflor 12% SC @ 225 ml/ha followed by sulfoxaflor 12% SC @ 200 ml/ha. The different doses of sulfoxaflor 12% SC i.e. 225 and 450 ml/ ha did not cause any phytotoxicity symptoms to potato crop besides this all treatments of insecticides not differ significantly population of natural enemies during study period.
