Isolation of 2,4 Diacetylphloroglucinol (DAPG) from fluorescent pseudomonads and investigation of its broad spectrum action against plant pathogens

Paper ID- AMA-20-11-2022-11827

A polyketide antibiotic,2,4 DAPG was isolated from fluorescent pseudomonads. It was found to have more antifungal action to Pythium aphanidermatum at a concentration of 150µl. The DAPG produced by Pseudomonas chlororaphis isolate PA23 recorded the highest percent inhibition of P. aphanidermatum over control. This compound in spite of its antifungal action against P. aphanidermatum, it also significantly inhibited the mycelial growth of Rhizoctonia solani, Sclerotium rolfsii and Fusarium oxysporum f.sp cubense. Similarly, the sclerotial germination of R. solani, S. rolfsii and Macrophomina phaseolina were completely inhibited by DAPG. It also caused hyphal distortion in P. aphanidermatum, R. solani, S. rolfsii and inhibited the spore germination of Alternaria solani and Botryodiplodia theobromae. Similarly, it inhibited the egg hatching of the root knot nematode Meloidogyne incognita and caused juvenile mortality under in vitro. This compound was detected by TLC with an Rf value of 0.88. HPLC studies also revealed the presence of 2 peaks viz 2,4 DAPG and MAPG with a retention time of 11.14 and 22.07 min respectively.

Impact of biochar types and pig manure on performance of ricebean in Dystrudept of Nagaland

Paper ID- AMA-19-11-2022-11826

A field experiment was conducted during the Kharif season of 2019-2020 and 2020-2021 under acidic soil conditions in Nagaland. The experiment was laid out in randomized block design with 11 treatments and 3 replications. Growth and yield parameters were recorded. The data were analyzed and computed statistically to compare the treatment effect. The plant height, number of branches per plant, yield attributes, seed, stover yield and nutrient uptake are influenced significantly by the combined application of fertilizer, biochar, and pig manure. The highest values of these parameters were recorded with T9 (RDF + 2.0 t ha-1 pig manure + 5.0 t ha-1 wood biochar) treatment. The T9 treatment increased seed yield by 86.3% and 76.1% and stover yield by 30.8% and 30.3% during 2019-2020 and 2020-2021, respectively. From the experiment conducted, ricebean responded well to the combined application of biochar, pig manure, and fertilizer.

Effect of Different Decomposer Application in Shredded Trashes and Raw Trashes Composting and its Influence on Soil Nutrients and Productivity of Sugarcane in Alfisols of Tiruchirappalli District

Paper ID- AMA-19-11-2022-11825

Sugarcane cultivation is proud to the farming community as its useful in the production of high-value products. In addition, it produces voluminous trash which is nutrient-rich biomass. Burning of sugarcane trash has caused health-related issues as well as acted as an important factor in global warming. The aim of this study was to convert trashes into compost by degrading it through microbial inoculants. The study consists of three treatments, PUSA decomposer (4 capsules/tone of trash), TNAU Biomineralizer (2kg/tone of trash) and Cow dung slurry (5%) with shredded trashes and raw trashes. A more sugarcane cane yield of 87.2tha-1 was recorded in PUSA decomposer treated plot and it was 7.12 % over the control plot (81.4 kgha-1). More microbial population in the surface layer was 19.96 x106/g, 8.36 x103/g and 6.99x103/g of bacteria, fungi and actinomycetes respectively in the PUSA decomposer applied treatment in shredded trashes followed in TNAU Biomineralizer with raw trashes applied plot (19.63(x106/g), 8.30 (x103/g) and 6.74(x103/g) respectively) when compared to control. Further, use of implements like shredder helps in rapid decomposition and eventually increases the soil nutrient stages. The results shows that, in-situ sugarcane trash composting has increased the organic carbon, available nitrogen, available phosphorus and available potassium content in soil from 0.34 to 0.0.39%, 228.7 to 268.2 kgha-1, 7.80 to 9.91kgha-1 and 354.0 to 394.5 kgha-1 respectively. Therefore, in-situ composting with efficient decomposers like PUSA decomposers and TNAU Biomineralizer can be a good alternate to mitigate these problems.

SEED BIO-PRIMING WITH PGPR ON IMPROVING PLANT GROWTH CUCUMBER UNDER INVITRO AND INVIVO CONDITIONS

Paper ID- AMA-19-11-2022-11824

The study was conducted to evaluate the microbial seed priming technique in cucumber using Plant Growth Promoting Rhizobacteria (PGPR) and Biocontrol Agents (BCAs) for uniform seedling emergence, fast and early growth to escape the plants from biotic and abiotic stress both under green house and field condition. The treatment T9 (microbial primed with (Az.b + B.m +P.f + T.h)) had enhanced the plant growth by increasing the mean no. of leaves to 34.44 with the lengthiest internode of 21.20 cm/pl with more no. of internodes that 21.65, compared with the unprimed control (7.68, 4.95cm/pl and 6.50) respectively in green house condition. The same trend was followed in field also. The number of days taken for tendril initiation and 50 per cent flowering was 21.69 and 41.01 in green house and 30.57 and 43.92 under field condition. It was very early when compared with the unprimed control. It took 46.42 and 71.11 mean no. of days to initiate the tendril and to attain 50 per cent flowering in control under field condition. Microbial seed priming also influenced the yield parameters, viz., Average no. of fruits/pl (27.75) and enhanced the fruit weight of 298.09 g/fruit which is about 8.27 kg of yield / pl. in the best treatment T9. The average fruit weight (179.81 g/fruit) and yield (2.17 kg/pl.) is very low in unprimed control. From the above experiment, it was clearly shown that microbial seed priming has a definite impact/ influence of enhanced growth and yield in cucumber.

Augmenting the productivity of Barnyard millet through crop establishment and nutrient management techniques in sodic soil

Paper ID- AMA-19-11-2022-11823

Barnyard millet is one of the hardiest, climate resilient and fast growing crop that is bestowed with high nutrient content in grains. An experiment was carried out in barnyard millet under natural sodic soil condition to study the effect of different methods of crop establishment and to optimize the nutrient requirement for barnyard millet (Kudiraivali) under sodic soil condition using the short duration high yielding variety Co (KV)2 during kharif season in 2016 at Anbil Dharmalingam Agricultural College and Research Institute. The experiment was carried out in FRBD comprising two factors viz., crop establishment techniques like line sowing at 25 x 10 cm (E1) and 35 x 10 cm (E2) and transplanting at 25 x 10 cm (E3) and 35 x 10 cm (E4) and nutrient management practices of N1 at 75 %, N2 100% and N3 125 % recommended dose of fertilizers. The experiment was replicated thrice. Totally twelve treatment combinations were analyzed. Results revealed that transplanting of barnyard millet at 35 x 10 cm with 125 % RDF recorded higher grain yield of 980 kg/ha with increased growth parameters like plant height, number of tillers and yield attributes viz., number of panicles, length of panicle and weight of the panicle in sodic soil.
