Effect of different nitrogen levels on the growth performance of wheat genotypes in the Indo-Gangetic Plains

Paper ID- AMA-06-03-2023-12090

Nitrogen (N) is a star nutrient for crop production. The uptake and assimilation of N are crucial steps for plant growth and development. This study aimed to evaluate the growth parameters of ten genotypes, namely HD 3226, HDCSW 18, HD 2967, HD 3086, HD 3249, HD 2733, PBW 550, PBW 343, HD 3117, and HD 3298, under varying levels of N [0, 50% (75 kg ha-1), and 100% (150 kg ha-1)] with the used of Neem oil coated urea in 2020 and 2021. The results showed that the different genotypes exhibited varying growth parameters, with plant height (PH), tiller numbers, and dry matter accumulation (DMA) being higher in 100% N as compared to the 50% and 0%. The results of this two-year study indicate that the average PH at 30 DAS and 90 DAS increased by 51.6% and 64.2% respectively with 50% RDN and by 17.6% and 22.18% respectively with 100% RDN, compared to the control. Similarly, the tiller numbers and DMA at 30 DAS increased by 20.4% and 26.5% respectively with 50% RDN, and by 37.5% and 51% respectively with 100% RDN, compared to the control. Among all genotypes, the highest PH (30 and 90 DAS) and DMA (30 DAS) were observed in genotype ‘HD-3249’, while the highest number of tillers (30 DAS) was observed in genotype ‘PBW-550’. The results of this study suggest that the genotypes ‘HD-3249’ and ‘PBW-550’, when application of 100% RDN, showed a promising response in terms of PH, DMA, and tillers numbers.

Effect of functionalized clay minerals and redmud on the bioavailability of arsenic

Paper ID- AMA-04-03-2023-12084

A pot experiment was conducted during the winter (rabi) season of 2020-21 to assess the effect of modified clay mineral and redmud (Fe-bentonite, DMSO-bentonite and Fe-redmud) on Arsenic (As) uptake and yield attributes of Indian mustard [Brassica juncea (L.) (Variety- Rohinga bullet)]. Significant reduction in As concentration in the grain and stem due to application of modified clay mineral and redmud was observed. However, Fe-bentonite, DMSO-bentonite and Fe-redmud reduce plant grain and stem As content @ all the applied doses (except control pot), but application @ 5.00 g kg-1 soil was found most significant as compare to the control pot and 1.25 g kg-1. Soil treated with iron modified bentonite, DMSO-bentonite and Fe-redmud resulted in significantly higher stem biomass and grain yield of mustard as compared to the control pot. Between the treatments, highest stem weight (g pot-1) of mustard plant was recorded at higher dose of Fe-bentonite followed by DMSO-bentonite and Fe-redmud but higher grain yield (g pot-1) was found higher in case of higher dose of Fe-Redmud.

Effect of climatic factors at different agroecological zones on seed yield and quality of hybrid maize COHM 8

Paper ID- AMA-04-03-2023-12082

A study was conducted at three different agroeclogical zones (southern, western and north eastern zones) of Tamil Nadu to assess the effect of climatic parameters on seed yield and quality of maize hybrid COHM 8 during rabi, 2021. One of the major factors affecting maize seed production is weather and this proposed work was attempted to ascertain the suitability of different weather parameters at different growth stages of maize hybrid on seed yield and quality. Seed crop was raised at all three locations with three dates of sowing at 15 days intervals (2nd fortnight of September, 1st fortnight of October and 2nd fortnight of October). In the present study, the erratic rainfall along with lower temperature and relative humidity experienced in southern zone and north eastern zone had a great impact on crop growth during different growth stages of seed crop of maize and thus results in lower yield. In southern zone, 2nd fortnight of October resulted in higher seed yield (4082 Kg/ha) compared to yield of 2nd fortnight of September (2721 Kg/ha) or 1st fortnight of October (2397 Kg/ha). In north eastern zone, 2nd fortnight of September recorded higher seed yield (3919 Kg/ha) than at 1st fortnight of October (2503 Kg/ha) and 2nd fortnight of October (2277 Kg/ha). In western zone, all the three dates of sowing registered higher seed yield which were on par to each other may be due to the favorable weather attributes along with required rainfall during peak growth stages. The results confirmed the importance of temperature, rainfall and relative humidity on the growth of the crop to obtain higher seed yield.

Influence of Irrigation Levels, Crop Geometry and Mulches on Okra (Abelmoschus esculentus (L.) Moench) Grown under Drip System in Arid Region

Paper ID- AMA-03-03-2023-12080

The field experiments were conducted at Instructional Farm, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner, for two consecutive Kharif seasons in 2018 and 2019. Experiments were conducted in a split plot design and replicated three times. In the main plot, four irrigation levels (40, 60, 80, and 100 percent PE), in the sub-plot, two crop geometry (normal sowing at 50 cm row spacing and paired row sowing at 30 cm x 70 cm) and in the sub-sub plot, three mulch (no mulch, straw, and plastic mulch) were assigned. Different irrigation levels, crop geometry and mulch treatments had significant impact on okra growth and quality. Pooled mean results showed that irrigation at 100 percent PE gave highest plant height at 50 DAS (73.42 cm) and harvest (116.79 cm), leaf area index at 50 DAS (3.31) and harvest (4.90), number of branches plant-1 (3.53) and chlorophyll content of leaves at 50 DAS (2.04). Irrigation level of 100 percent PE recorded highest NPK content (1.483, 0.222, 1.493 percent, respectively) and T.S.S. content (3.38 °Brix) but all these attributes were statistically at par with 80 percent PE. Results further showed that paired row sowing at 30 cm x 70 cm gave highest plant height at 50 DAS (68.43) and at harvest (111.9), leaf area index at 50 DAS (3.22) and harvest (4.26) and number of branches plant-1 (3.26) over normal sowing. Growth attributes and quality attributes were all highest in straw mulch, which were at par with plastic mulch.

Bioefficacy and residual study of selected insecticides against cabbage aphid (Brevicoryne brassicae L.) on cabbage

Paper ID- AMA-02-03-2023-12075

A research program was designed to check the efficacy of different insecticides against cabbage aphid during ‘rabi’ season of 2017-18 and 2018-19. From the results it concluded that malathion 50 % EC (82.10 %) was most effective as it cause maximum reduction in population of aphids w.r.t control, followed by nimbecidine 0.03 % EC (71.77 %) whereas, Bacillus thuringiensis var. kurstaki 0.05 % WP (49.93 %) was found least effective insecticide. However, two sprays were found more effective in managing the population of aphid rather single spray. Persistence and residual toxicity of the most effective insecticide i.e., malathion 50 % EC revealed that it was persisted up to 15 days in cabbage at both single and double dose with half life value 1.78 and 2.40, respectively. The average residues of malathion at both dose in cabbage was found below MRL (Maximum Residue Limit) i.e., 3.0 mg kg-1.
