Stability Analysis of Rice Hybrids for Grain Yield in Telangana through AMMI and GGE Bi-plot Model

An investigation was carried out on fifteen rice genotypes to identify stable rice hybrids across six different agroclimatic zones in Telangana state using AMMI and GGE bi-plot analyses during July to November, 2020. Analysis of variance clearly showed that environments contributed highest (65.47%) in total sum of squares followed by genotypes×environments (21.19%) indicating very greater role played by environments and their interactions in realizing final grain yield. AMMI analysis revealed that rice hybrids viz., RNRH 39 (G6), 27P31 (G14) and RNRH 15 (G1) were recorded higher mean grain yield with positive IPCA1 scores. The hybrids, JGLH 275 (G11) and JGLH 365 (G15) were plotted near to zero IPCA1 axis indicating that these hybrids are relatively more stable across locations. GGE bi-plot genotype view depicts that the hybrids, JGLH 365 (G15) and US 314 (G8) were inside the first concentric circle and found to be more stable across environments. GGE bi-plot environment view showed that Rudrur (E4) location was the most ideal environment. However, Warangal (E6) and Jagtial (E1) locations were poor and most discriminating. Depending on dispersion of environments in different directions, six locations were partitioned into three mega zones as first zone comprised of four locations viz., Kunaram (E2), Kampasagar (E3), Rudrur (E4) and Rajendranagar (E5) whereas highly dispersed Jagtial (E1) and Warangal (E6) were identified as two separate mega environments. The bi-plot view identified that 27P31 (G14), JGL 24423 (G2) and RNRH 39 (G6) were the best performing genotypes in first zone comprising four locations.

STUDY ON ICHTHYOFAUNAL DIVERSITY IN RELATION TO PHYSICO-CHEMICAL PARAMETERS OF MANAKONDUR FRESH WATER LAKE OF KARIMNAGAR DISTRICT, TELANGANA STATE, INDIA

Freshwater bodies are one of the most common and stable habitats of biosphere. The freshwater habitats have their own physico-chemical and biological characters which are subjected to modify by local conditions and physiographic features. The water quality parameters have a great influence on the growth and other factors of aquatic organisms. Therefore, the lentic water body gives a good source for fisheries. The present investigation deals with limnological and physico-chemical parameters and their influence on Ichthyofauna abundance in Manakondur fresh water Lake at Karimnagar District, Telangana State.

Influence of Different Drip Irrigation and Fertigation Levels on Yield and Economics of High-density Cotton

An experiment was conducted to study the effect of different drip irrigation and fertigation levels on yield and economics of high-density cotton at College of Agriculture, Professor Jayashankar Telangana State Agricultural University, Hyderabad, during kharif 2019 and 2020. The experiment consisted of twelve treatments laid out in Factorial randomised block design (FRBD) replicated thrice. Three irrigation levels (irrigation scheduled at 0.6 [I1], 0.8 [I2] and 1.0 [I3] Epan throughout the crop growth period) and four fertigation levels (application of 100% RDNK in differential dosage as per recommendation [F1], application of 100% RDNK in differential dosage as per crop coefficient curve [F2], application of 125% RDNK in differential dosage as per recommendation [F3], and application of 125% RDNK in differential dosage as per crop coefficient curve [F4],) were included as treatments in this study. Irrigation levels did not show any significant influence on yield and economics during 2020 and 2021. While among the four fertigation levels, application of 125% RDNK in differential dosage as per crop coefficient curve (F4) recorded significantly higher gross returns, net returns and B:C ratio which were on par with application of 125% RDNK in differential dosage as per recommendation (F3). Lower gross returns, net returns and B:C ratio were obtained with the application of 100% RDNK in differential dosage as per recommendation (F1) which were on par with application of 100% RDNK in differential dosage as per crop coefficient curve during both the seasons (F2). Further the gross returns and net returns produced under F3 was also on par with F2.

Palaeoclimatic significance of non - striate disaccate pollen in Yellandu coalfield of Godavari graben, Telangana State

The present palaeopalynological study deals with the significance of non - striate disaccate pollen from bore hole Q - 563 of Yellandu coalfield (Jawahar Khani - 5 coal block), Kothagudem sub-basin and to determine the age and palaeoclimatic interpretations of the study area based on the pollen morphological characters. For the palynological investigation, sixty samples were thoroughly analyzed in which fairly diversified palynofloral assemblages of Gondwanic affinity were recorded. About 30 genera and 50 species of palynomorphs, belong to Glossopteridales, Coniferales, Cordaitales of gymnospermous pollen, pteridophytic spores. In the present communication, the palynoflora belongs to Glossopteridales viz. Scheuringipollentites barakarensis, S. maximus, S. tentulus, Ibisporites diplosaccus, Primuspollenites levis, P. densus and Sahnites thomasii etc. Frequency distribution pattern of the palynotaxa reveals that the assemblage is dominated by the non - striate disaccates followed by striate disaccates, monosaccates (gymnosperms) and pteridophytic spores. The diversified palynoassemblage of both non striate and striate disaccates pollen strongly signifies that the Yellandu coal belt of Godavari graben belongs to Barakar Formation of Early Permian age (Late Sakmarian – Early Artinskian). Predominance of non - striate disaccate pollen recorded from the Yellandu sediments indicates a warm and high humid climatic condition with fluvial environment of deposition.

An Analysis of Pattern of Floral Waste Generated and Disposal in Hyderabad City of Telangana State

Flowers are an integral part of Indian culture and tons of flowers often gets accumulated at religious sites like temples, mosques, churches and gurudwaras due to a number of religious practices and it is also generated in places like wedding ceremonies, flower markets, residential areas, etc. But sadly, most of these flowers often thrown in water bodies and garbage, creating an environmental hazard. Hence, the present study was taken to analyse the floral waste generation pattern and their disposal in the city. A total sample of 62 floral waste generators consisting of 30 temples, 12 function halls and 20 flower shops was selected for the study. Data was analysed and tabulated. The study analysed that the bigger temples contribute to higher floral waste generation, and the festival seasons around the year also generates more floral waste. The function halls don’t generate a constant quantity of floral waste and the usage of flowers highly depends on the budget and theme of the ceremony. The flower markets generate more floral waste if the sales are less in the market. The flowers such as Chrysanthemum, Marigold Jasmine and Rose are generated as major category of floral waste.

First Report of Canine Bufavirus and Its Whole Genome Sequence in India

Canine bufavirus (CaBuV), a novel protoparvovirus of dogs was reported only in Italy and China, till date. It was detected from dogs with enteric and respiratory symptoms and is distantly related to the human bufavirus. To explore the enteric prevalence of CaBuV in India, 186 diarrheic faecal samples were collected in Telangana State between 2019 and 2020. Among the samples, 4.3% (8/186) were positive for CaBuV by PCR. Co-infection with canine parvovirus CPV-2 was seen in 75% (6/8) of CaBuV positive samples. The near complete genome (4292 bp) of CaBuV was amplified and reconstructed for one isolate 407/PVNRTVU/2020. Sequence alignment indicated 93.42–98.81% homology with the other available CaBuV sequences; 70.88-73.39%, and 54.4-54.8% identity with human bufavirus, and CPV-2, respectively. Phylogenetic analysis showed that CaBuV 407/PVNRTVU/2020 was most closely related to CaBuV Chinese strains, together separated as Asian lineage. All Bufaviruses clustered together in one clade; however, the bat and sea otter parvoviruses also showed close relation with Bufaviruses. This first report of prevalence of CaBuV in India provides a good reference, emphasizes the need for further epidemiological surveillance of CaBuV in India and its role in canine enteritis.

Rainfall and Temperature Trends in Jagtial District of Telangana State

Aims: To investigate and assess the significance of the potential trend of two variables viz. rainfall, temperature in Jagtial district of Telangana state. Place and Duration of Study: Data of Daily rainfall and temperature data of 39 years (1980-2019) collected from the meteorological observatory at Regional Agricultural Research Station, Polasa, Jagtial. Methodology: In this study, trend analysis has been carried out on monthly, seasonal and annual basis using the data period between 1980 to 2019 for rainfall and temperature. Mann-Kendall test and Sen’s slope estimate test were applied to identify the existing trend direction and magnitude of change over time. Results: The rainfall seasonal trend analysis indicates that pre-monsoon, monsoon and post-monsoon and winter period showed a negative rainfall trend with z statistics of-1.47, -2.51, -0.55 and-1.38 respectively. However, the annual rainfall showed a negative trend with a z value of -2.53. In the case of Sen’s slope shows that negative trend in monthly, seasonal and annual rainfall. But the significant rising trend of monthly, seasonal average temperature is noticed from 1980 onwards. The annual average maximum temperature in the Jagtial showed an increasing trend (Z value +5.03). An increasing trend in the all seasons will lead to increase in annual mean temperature. The results of minimum temperature shows a rising trend and falling trend observed Monthly. However annual mean minimum temperature in the Jagtial District showed an increasing trend (Z value 0.10). In the case of maximum temperature for the observed period, it showed rising trend (Sen's slope = 0.63) while the minimum temperature trend showed no trend (Sen's slope = 0.02). Conclusion: Time series was carried out using nonparametric M–K test and Sen's slope estimator, which are widely used tests for conducting trend analysis. Therefore, its take into think about the rainfall variability in particular and temperature variability in general of the area into their climate change adaptation approach.
