EFFECT OF RESIDUE MANGEMENT, NITROGEN MANGEMENT AND OSMOREGULATOR ON GROWTH OF RAINFED WHEAT

Paper ID- AMA-21-01-2025-13412

An investigation was carried out at Research Farm of Advanced Centre for Rainfed Agriculture, Rakh Dhiansar of Sher-e-Kashmir University of Agriculture Sciences and Technology of Jammu during Rabi season of 2022-23 and 2023-24 to study the effect of residue management, nitrogen management and osmoregulator on growth of rainfed wheat. The experiment consisting of three residue management practices viz. R1: Residue retention (Happy Seeder), R2: Residue incorporation (Super Seeder), R3: Conventional tillage and three nitrogen management viz., N1: 75 % of RDN, N2: 100 % of RDN, N3: 125% of RDN and two Osmoregulators viz., O1: 1.0 % KCl, O2: Water sprays. The results revealed that a significant increase in growth was observed in residue management residue incorporation (Super Seeder), nitrogen management in 125% of RDN and Osmoregulators in 1 % KCl.

Evaluation of barnyard millet germplasm for morphometric characterization, genetic diversity and screening against important endemic diseases in hills of Uttarakhand

Paper ID- AMA-20-01-2025-13409

In India, barnyard millet holds a significant importance, being cultivated as a climate resilient, dry land crop across a wide range of environmental conditions in poor and marginal soil under rainfed conditions for its highly nutritious grains as well as fodder, due to its diverse adaptive mechanisms. Availability of high yielding improved varieties with stable genetic resistance towards important endemic diseases are the utmost need in hills of Uttarakhand under the present scenario of climate change. Germplasm is an essential reservoir of favourable alleles for agronomic and quality traits. The detailed characterization will serve the requirement of long-term goals in plant breeding viz., climate change, duplicity of germplasm, depleting natural resources, trait specific resistant donors, and available genetic resources adapted to present climatic conditions. Therefore, the documentation of available germplasm is important to serve the near future goals of crop breeding programme. Considering the significance of the crop, one study was conducted using one hundred fifty-four germplasm lines of barnyard millet including four checks viz., PRJ-1, VL-172, VL-207 and DHBM-93-3 and those were planted in an augmented design. During the study, observations were recorded at different growth stages of barnyard millet for different visually assessed morphological qualitative traits, agro-morphometric quantitate traits, genetic diversity, and disease resistance. During the investigation, it was observed that a significant difference was present among the studied germplasm. The quantitative traits showed more than 75% heritability along with moderate to high genetic advance except days to maturity. The values for genotypic and phenotypic coefficient of variation were almost similar indicating that there was a less influence of environmental factors on the characters studied. From the present investigation, two germplasm i.e. BAR-1403 and BAR-1186 were identified as potential germplasm for grain yield and fodder yield having resistance for all endemic diseases of barnyard millet. These two germplasm lines from the bulk are of tremendous value and hold potential to be further used in the breeding programme to develop high yielding disease resistant improved varieties of barnyard millet.

Incidence and management practices of mango bark eating caterpillar, Indarbela quadrinotata in Bihar, India

Paper ID- AMA-19-01-2025-13404

Mango is an important fruit crop and affected by several insect pests and diseases. Among insects, bark eating caterpillar is a serious problem in Bihar and causes heavy losses. An investigation was conducted for incidence of this insect and its management. The study on incidence of bark eating caterpillar Indarbela quadrinotata Walker revealed that young orchards of mango were less prone to bark eating caterpillar infestation in comparison to old orchards. In management practices it was found that poorly managed young orchards of mango had only 20.40 per cent infestation in comparison to 90.05 per cent in old orchards. Among different management practices evaluated, cleaning the infected hole + plugging holes with cotton swab dipped in lambda cyhalothrin 5 EC @ 1ml/litre + plugging holes with mud showed maximum mortality (81.33% in 2019 and 82.68% in 2020) of bark eating caterpillar with highest yield (48.80 t/ha and 50.30 t/ha during 2019 and 2020, respectively) and increased yield over untreated control as 156.84 per cent and 171.89 per cent in 2019 and 2020, respectively.

TREND ANALYSIS OF CLIMATIC PARAMETERS IN THE CAUVERY DELTA REGION OF TAMIL NADU IN INDIA

Paper ID- AMA-16-01-2025-13402

Climate data on maximum and minimum temperature, relative humidity, air velocity and rainfall were collected from the concern District Collectorate and Agro Climate Research Centre, TNAU, Coimbatore for three districts (Tiruchirapalli, Thanjavur, and Pudukkottai) in the Cauvery delta region of Tamil Nadu, India, over a 10-year period (2009-2018). The average monthly maximum temperature (°C) was highest in May (38.30 ± 0.34 to 38.70 ± 0.40), and lowest in December (29.20 ± 0.20 to 30.00 ± 0.33). The average monthly minimum temperature (°C) was higher in May (28.30 ± 0.21 to 29.30 ± 0.21) but declined in January (19.70 ± 0.26 to 20.70 ± 0.15). The average monthly humidity (%) was high in November (78.30 ± 1.80 to 79.50 ± 1.65) and low in June and July (49.20 ± 1.63 to 50.60 ± 1.19). The average monthly air velocity (m/s) was more in June and July, ranging from 4.27 ± 0.20 to 4.69 ± 0.17, and least in October, ranging from 2.52 ± 0.12 to 2.79 ± 0.15. The average monthly rainfall (mm) was high in November (149.68 ± 36.44 to 225.20 ± 44.83) and low in February (3.41 ± 1.84 to 5.21 ± 2.33). During 2009-2018, the Mann-Kendall trend test revealed a significant (P<0.01) increasing positive trend for maximum and minimum temperatures and a non-significant decreasing negative trend for relative humidity, with the exception of Thanjavur district, where there was a significant (P<0.01) decrease in relative humidity. Similarly, the Mann-Kendall trend test indicated a non-significant increasing positive trend of air velocity but no trend in rainfall during the last decade (2009 to 2018) in Cauvery delta region of Tamil Nadu.

Morpho- Molecular Characterization of inbreds and hybrids for drought tolerance in maize (Zea mays L.)

Paper ID- AMA-16-01-2025-13401

The experiment was carried out to screen eight maize inbreeds (parents of F1s) and their twenty eight F1s along with two checks (DHM 117 and P 3522) for drought tolerance in maize on the basis of morphological and biochemical parameters during rabi 2023-24 in RBD design. The analysis of variance showed that inbreeds as well as their hybrids were highly significant for all the traits in normal condition except anthesis silking interval, cob girth and kernel row per cob whereas, in drought condition anthesis silking interval and ear height were significant and remaining all the traits were highly significant. The mean value of grain yield was ranged from 2778.09 to 11311.25 kg/ha and 1699.55 to 8696.41 kg/ha in normal and drought condition respectively. For most of the traits under consideration, check P 3522 was found superior under normal as well as drought condition. In drought condition, inbreeds SML 1, CML 451, CLO 2450 and BML 6 and cross combination CLO 2450× SML 1 (8696.41 kg/ha) and CLO 2450 × BML 6 (8516.38 kg/ha) showed significant higher grain yield. Molecular characterization was done using 22 SSR primers in which 17 primers showed amplification. The Polymorphism Information Content values of alleles ranged from 0.46 (Phi046) to 0.81(Phi059). Therefore selection of inbreeds viz., SML 1, CML 451, CLO 2450, BML 6 and their cross combination could be a better option for breeding programme associated with drought tolerance.
