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.

Yield ans quality attributing traits of guava cv. Hisar safeda as influenced by plant growth regulator and soluble fertilizer

Paper ID- AMA-01-03-2023-12072

To study the effects of growth regulator on flower regulation, yield and quality of guava cv. Hisar Safeda was carried out at Fruit Orchard Sarkaria Farm, Fatehpur Rajputan (Patiala) during the year 2019-20 and fruit analysis was undertaken in Post Graduate Laboratory, Department of Agriculture Science, Mata Gujri College, Sri Fatehgarh Sahib. The experiment was laid out in a Randomized Block Design (RBD) having nine treatments with three replications. Treatments consisted of NAA @ (300, 400 and 500 ppm), Ethrel @ (1000, 1500 and 2000 ppm), Urea (5% and 10%) and Manual Bud Removal (MBR), while the plants sprayed with water served as the control. Significant variations were recorded during investigation with different treatment of Ethrel, NAA and urea on vegetative growth, flowering, yield and quality of guava cv. Hisar Safeda. In rainy season, maximum fruit length, fruit breadth and fruit weight was recorded in treatment of Ethrel @2000 ppm. However, during winter season maximum fruit length, fruit breadth and fruit weight was recorded in Control (Water spray). Highest fruit firmness was recorded in fruits under control treatment (water spray) during both season of study. Treatment combination of Ethrel @2000 ppm showed maximum and significant increased in quality characteristics viz. TSS, ascorbic acid, total sugars, reducing sugars and non-reducing sugars.

Seaweed nano powder as dry dressing treatment and its effect on the physiological performance in Bhendi seeds var. Arka Anamika (Abelmoschus esculentus L.)

Paper ID- AMA-01-03-2023-12071

In Today’s agriculture, seaweed serves as an organic rich product possessing rich source of growth promoting substances such as IAA, kinetin, zeatin, gibberellins, auxins, cytokinins, metabolic enhancers, macro and micro elements, amino acids and vitamins. The experiment was aimed to evaluate the effect of seaweed invigoration treatments on physiological performance of bhendi seeds in the Department of Seed Science and Technology Laboratory, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai. Seaweed nano powder of Sargassum myricocystum and Kappaphycus alverzii were ball milled for 2h and dry dressed on bhendi seeds @ 1, 2, 3 and 4 g/ Kg of seeds for 0.5h, 1h and1.5h of shaking durations were subjected for seedling evaluation test. The results revealed that, among all the dry dressing treatments, seeds treated with Sargassum myricocystum @ 1g/kg for 0.5h and Kappaphycus alverzii @ 2g/kg for 1h, registered higher seed quality parameters. Seed germination of bhendi significantly exhibited in Sargassum myricocystum 1g/kg for 0.5h and Kappaphycus alverzii 2g/kg for 1h. Radicle length, plumule growth, seedling vigour index I and II, dry matter production and other germination attributes increased by the application of seaweed nano powder. Seaweed nano powder was found to contain higher growth promoting substances, when analysed using GC-MS analysis.
