PERFORMANCE OF LOCAL CHAKHAO (BLACK RICE) GENOTYPES OF MANIPUR THROUGH STUDIES OF CORRELATION AND PATH ANALYSIS.

Paper ID- AMA-23-11-2022-11833

17 genotypes of Chakhao (black rice) varieties which are found locally in Manipur were evaluated under experimental rice field at Mongsangei, near SSB, Imphal west during two consecutive Kharif seasons of 2019 and 2020. Data were recorded on thirteen quantitative characters and the analysis of variance revealed highly significant for all the traits in both the year and on data pooled over years, indicating the presence of considerable amount of variability among the genotypes. High estimates of GCV and PCV was observed for number of effective tillers per plant, highlighting the presence of wider variability for this character as compared to other characters. High heritability along with high genetic advance were observed for grain yield per plant, number of spikelets per panicle and number of filled spikelets per panicle. Correlation studies showed that Grain yield per plant exhibited significant positive correlation with the characters tillers per plant and effective tillers per plant at both genotypic and phenotypic level. And at the phenotypic level for the characters plant height, number of spikelets per panicle and number of filled spikelets per panicle. For path analysis, the highest direct effect was exhibited by no. of effective tillers per plant followed by no. of days to 50% flowering, no. of filled spikelets per panicle, flag leaf length and plant height in both genotypic and phenotypic level. Highest indirect positive effect was revealed by no. of tillers per plant through no. of effective tillers per plant. Also panicle length, plant height, no. of spikelets per panicle, no. of filled spikelets per panicle and no. of tillers per plant showed high indirect effect through no. of effective tillers per plant in both genotypic and phenotypic level. The study concluded that, Chakhao Poireiton A can be used as a promising genotype since it exhibited high grain yield per plant, high no. of spikelets per panicle, and highest no. of effective tillers per plant.

Influence of Sowing Dates and Irrigations on Prevalence of Chickpea (Cicer Arietinum L.) Dry Root Rot Disease Under Field Conditions

Paper ID- AMA-23-11-2022-11830

Chickpea (Cicer arietinum L.) popularly known as Gram is an important pulse crop in India. Rhizoctonia bataticola (Taub.) is one of the most destructive fungal pathogen causing dry root rot disease in chickpea. The disease is most severe in the central and southern zones, where the crop is grown mostly under rainfed condition. The different dates of sowing at 15 days of intervals and were given alone and in combination also to see their effect on disease incidence. The susceptible variety “Uday” was used for this experiment. The crop which had been sown on October 15, 2017, the disease was first appeares on 90 DAS in *D1 I1 (15th Octoober + first irrigation at pre-flowering times ) followed by D1 I2 (15th Octoober + first irrigation at pre-flowering times and 2nd irrigation at pod formation stage) and D1 I3 (15th Octoober + first irrigation (40-45 DAS), 2nd irrigation pre –flowering times ) and 3rd irrigation at pod formation stage) which were (100 DAS) and (110 DAS), respectively. The crop which had been sown on October 15, 2017, the minimum disease incidence was observed (16.41%) in D1I3 followed by D1I2 and D1I1 which were (19.30%) and (21.80%), respectively. In the case of 01 November, 2017 sowing date the minimum disease incidence was observed (31.5%) in D2I3 followed by D2I2 and D2I1 which were (34.50%) and (35.5%), respectively. While 3rd date of sowing on 15 November, 2017, the minimum disease incidence was observed (36.43%) in D3I3 followed by D3I2 and D3I1 which were (37.73%) and (39.93%), respectively during 2017-2018 and similar trends were also observed in 2018-19. However, the minimum disease incidence and maximum seed germination, plant disease control and yield were found in the first date of sowing (October 15) with three irrigations in comparison to the second and third date of sowing with one or two irrigations during 2017-2018 and similar trends were also observed in 2018-19. The interaction effect was significantly different between various dates of sowing and irrigations.

Comparative economic analysis of Indigenous and clonal eucalyptus in Punjab

Paper ID- AMA-23-11-2022-11829

The present study was an attempt to make economic comparison between indigenous and clonal variety of eucalyptus. The study was conducted in the Hoshiarpur and Muktsar districts of Punjab state. The data pertained to the year 2015-16 and were collected from 70 farmers which were growing eucalyptus on their farm land as block plantation. The number of farmers growing indigenous and clonal variety were 32 and 38 respectively. There was not much difference found in establishment cost of both varieties irrespective of sapling cost. It was found that sapling cost was more in case of clonal eucalyptus. The total difference of Rs 2931 was observed in the establishment cost of both the varieties. In operational cost, the expenditures were almost same irrespective of cost of fertilizer and manure as clonal variety needs more irrigation and fertilizer and manure. Both the varieties have too much difference in terms of returns as clonal eucalyptus was highly profitable than indigenous eucalyptus. The net returns of indigenous eucalyptus were Rs 192329 in seventh year whereas Rs 355289 in case of clonal eucalyptus giving extra benefit of Rs 162960. The annuity value also increased with the increase in age of indigenous and clonal eucalyptus. It was clearly observed that clonal variety was more profitable than indigenous variety of eucalyptus.

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.
