Influence of ecosystem on population dynamics of predators in mulberry, Morus spp.

Paper ID- AMA-27-02-2023-12066

Population dynamics of insect predators in the agroecosystem and forest ecosystem of mulberry, Morus spp., were documented in villages of Annur block, Coimbatore and at Forest College and Research Institute, Mettupalayam campus of Coimbatore district, Tamil Nadu, India, during 2020–2022. Fifteen species of predators were recorded and majority of them were coccinellids. Variations in the diversity, species richness, and evenness in the different ecosystems were studied and the result revealed that Shannon-Weiner index (3.162) and evenness index (0.98) were found to be higher in forest ecosystem compared to agroecosystem. The results also confirmed that the diversity of crop and the food availability influenced the predator population which serve as means of biological control of pest in mulberry.

THE COMBINED EFFECT OF HERBICIDES ON GROWTH, YIELD AND ECONOMICS OF WHEAT (Triticum Aestivem L.)

Paper ID- AMA-26-02-2023-12064

A field experiment was conducted during 2016-17 and 2017-18 at Hill Agricultural Research and Extension Centre, Bajaura (Himachal Pradesh), India to study the response of wheat (Tritucum aestivum L.) to different herbicidal treatments. The experiment was conducted in a randomized block design with eleven treatments and in three replications. The experimental results revealed that application of pre-mix herbicide Metsulfuron + Carfentrazone + Surfactant at 32 days after sowing recorded the maximum degree of reduction in the density as well as dry matter of broad-leaved weeds at 30 DAS compared to the remaining treatments. A significantly higher yield attributes of wheat were recorded in Metsulfuron + Carfentrazone + Surfactant treatment while significantly yield attributes of wheat was recorded in weedy check treatment. Higher yield (straw and grain) and weed control efficiency of wheat was recorded in Metsulfuron + Carfentrazone + Surfactant treatment while lower grain yield, straw yield and weed control efficiency was recorded in weedy check. Hence, highest gross returns (142.6 × 103 INR ha-1), net returns (100.1 × 103 INR ha-1) and B: C ratio (2.35) were obtained from Metsulfuron + Carfentrazone + Surfactant treatment 4 + 20 g a.i. ha 1 treatment.

Radial and Axial variation in specific gravity of Pterygota alata at different girth classes

Paper ID- AMA-26-02-2023-12063

The study was conducted at Forest College and Research Institute, Mettupalayam, during 2019 to 2022, to determine the specific gravity of Pterygota alata at different girth classes. The samples were collected from seed origin of Pterygota alata which were farm grown in Pollachi, India with a specification of four different girth classes (30-45, 45-90, 120-150,150-180cm) and three radial and axial positions. From each sample tree, three stem discs with a 2 cm thickness were cut in both the axial (25, 50 and 75 % height of the tree) and radial (pith, middle and periphery) position then the samples were converted to the 2×2×2 cm3 cubes. The highest specific gravity at radial position was observed in 150-180 cm girth class with a value of 0.67, 0.58 and 0.44 g/cm3 in green, air dry and oven dried wood samples and the lowest specific gravity was recorded in 30-45 cm as 0.629, 0.629 and 0.432 g/cm3 respectively. Whereas in axial position the highest specific gravity was observed in 150-180 cm girth class with a value of 0.69, 0.59 and 0.44 in green, air dry and oven dried wood samples and the lowest specific gravity was recorded in 30-45 cm as 0.62, 0.50 and 0.44 respectively. The study suggested that the Pterygota alata specific gravity is more of less similar to the low-density hardwood species and it will be the alternate prominent species for ply wood, packing cases, match splints and pencil industries.

Management of white grub (Holotrichia serrata) in sugarcane in North East Zone of Tamil Nadu

Paper ID- AMA-25-02-2023-12059

Farmer participatory field experiments were carried out at Enthal village in M/s Dharani sugars Ltd, Polur command area and at Andiyappanur village in M/s. Tiruppattur co-operative sugar mill Ltd, kethandapatti command area of North East Zone of Tamil Nadu during 2015-2018 to develop management technique with insecticides against white grub (Holotrichia serrata, Scarabaeidae, Coleoptera). The sugarcane varieties, CoC 24 and Co 86032 were ratooned during last week of January of respective years affected with white grub has been selected. Six insecticides (listed in table) applied as soil drenching/soil application in root zone affected clumps along with untreated check replicated thrice in randomized block design. The treatments were imposed in the third week of June of respective years. The observations on the number of white grubs per meter row in the root zone were recorded a day before and 15, 30, 45, 60th days after treatment applied and percent reduction was worked out. The yield parameters were recorded at the time of harvest. The highest (100%) grub population reduction was recorded in imidacloprid and Chlorantraniliprole on 15th day after application. It was concluded that soil drenching of imidacloprid 17.8 SL @ 250 ml/ha in root zone of affected cane were very effective in reducing white grub population within 15 days of application and recorded highest cane yield of 87.39 t/ha with CCS of 12.88% which accounted for 38.77 % higher yield with higher cost benefit ratio of Rs. 2.76 than untreated control.

DIVERSITY AND GENOTYPE x ENVIRONMENT INTERACTION IN EXTRA EARLY BARNYARD MILLET GENOTYPES FOR GRAIN YIELD USING AMMI ANALYSIS AND GGE BIPLOT

Paper ID- AMA-25-02-2023-12055

Barnyard millet is a nutritious, small millet crop grown in rainfed condition, consumed just like rice. Reducing the duration for maturity is an important breeding objective and assessing the phenotypic diversity help in identifying those genotypes with desirable traits. Twenty-seven genotypes were subjected to D2 analysis which revealed the presence of eight different clusters. Cluster I had the maximum number of genotypes. Cluster II had five genotypes, cluster III had three genotypes and in cluster IV, V, VI, VII and VIII with one genotype each. Early maturing germplasm were in cluster III and the check MDU1 was in separate cluster VII. The percentage contribution of the traits towards divergence was maximum by grain yield/plant followed by plant height and net by days to maturity. Stability analysis of these genotypes in three different environments revealed the stable genotypes with high mean were ACM BM-20-019 and MDU1. E2 was the least interactive environment. Using What- Won- Where biplot, the three test environments were divided into two mega environments. In light of this, the genotype ACM BM-20-016 performs well in mega environment 1 (E1), while the genotypes ACM BM-20-019, MDU 1, and ACM BM-20-012 perform similarly in mega environment 2. (E2 and E3).
