Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Transcriptomics studies in bread wheat under terminal heat stress
    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-12) Kavita; Mukesh Kumar
    In the present investigation 50 wheat genotypes were sown with two replications in a randomized complete block design (RBD) at the experimental area of Department of Genetics and Plant Breeding, CCSHAU, Hisar, during Rabi seasons of 2018-2019 and 2019-2020 under normal and late sown conditions. Combined ANOVA showed that all traits had high level of genotypic variations among all the genotypes under both conditions. Highest heritability was shown by days to anthesis under both conditions while high GCV, PCV and genetic advance as percent mean were high for relative stress injury and chlorophyll stability index under normal and late sown conditions, respectively. Biochemical parameters and heat stress indices were used to screen out heat tolerant genotypes. Grain yield per plot exhibited positive and highly significant correlation with membrane stability index, chlorophyll stability index and all yield contributing traits under both conditions. Correlation among heat stress indices exhibited that grain yield per plot under both conditions is positively correlated with stress tolerance index, yield index, mean productivity, geometric mean and harmonic mean. Path analysis showed that harvest index and biological yield per plot had highly positive direct effects on grain yield per plot under both conditions. The principal component analysis for morpho-physiological traits under normal and late sown conditions and heat stress indices depicted that the first four, three and two components reflected more than 78%, 76% and 97% of the total variance, respectively. Cluster analysis grouped genotypes into 7 and 5 clusters, most divergent clusters were IV and VI, II and V under normal and late sown conditions, respectively. UPGMA cluster tree analysis divided genotypes into two clusters and also confirmed that sufficient variability is present among genotypes. Transcriptome analysis revealed that the differentially expressed genes (DEGs) under control and heat stress conditions were identified in both genotypes (WH-730 and WH-1184). These DEGs were utilised to set up a subsequent unigene assembly and GO analysis was done using unigenes to analyze functions of DEGs which classified into three main domains; biological process, cellular component and molecular function. KEGG ontology was used to visualize the physiological processes or to identify KEGG pathways that provide plants their ability to shield in adverse conditions of heat stress. From KEGG ontology it was reported that the gene encoded enzyme (peroxidase) of KEGG pathway was upregulated in WH-730 while downregulated in WH-1184.

    Crop residue management options and effects on soil properties and crop productivity under rice - wheat cropping system
    (CCSHAU, Hisar, 2021-07) Kavita; Dev Raj
    An experiment on residue management was conducted during Rabi, 2018 at Research Farm KVK, Panipat, CCS Haryana Agricultural University to study the effect of residue management options and fertilizer levels on soil properties and crop productivity under rice wheat cropping system. The experiment was laid out in spilt plot design consisted 4 residue management practices (R1: Residue removal, R2: Residue Burning, R3: Residue Incorporation and R4: Residue Retention ,Direct seeding of wheat with happy seeder into rice stubbles) in main plot and with five fertilizers level (F1: Control, F2: 100% N + 50% RD of P&K, F3: 100% N + 75% RD of P&K and F4: 100% N+75% RD of P&K+ Waste decomposer and F5:100% of RDF) in sub-plot. N and P mineralisation were highest at 25 and 55 DAS, respectively, values decline thereafter for both during first year whereas during second year value again increase at 115 DAS. MBC and enzymes values were also reported higher at 55 DAS during both the years. Urease and alkaline phosphatase followed same trend as mineralisation during both the year, however MBC and dehydrogenase followed the different trend during 2019-20. Burning of rice residue decreased the MBC, dehydrogenase and urease activity, however alkaline phosphatase activity increased after burning. The available N.P and K content in soil after rice harvest varied from 115 to 129 and 113 to 134, 24.6 to 44.2 and 25.2 to 48.2 and 175 to 193 and 176 to 196 kg ha-1, respectively among different treatment combination during 2019 and 2020, respectively. Available nutrient status in soil followed the order retention> incorporation> burning> removal under residue management and 100% RDF>100% N+75% RD of P&K> 100% N + 75% RD of P&K> 100% N + 50% RD of P&K> control in case of fertilizer level except for the Fe (higher under control) during both years. Higher value of TOC (0.800 and 0.814 %) and SOC (0.680 and 0.694 %) was reported with the retention treatment while mean value of MBC (350 and 379 mg/kg) and DOC (418 and 540 mg/kg) recorded higher under incorporation during both the year. Organic carbon fraction followed the order: recalcitrant > less labile> very labile> labile during both years. Lower value of bulk density and higher value of water holding capacity recorded with R4 treatment. Germination index was reported higher under removal and lowest value recorded with retention during both the year. The highest grain and straw yield of wheat was recoded with removal and 100% RDF during 2018-19 and retention and 100% RDF during 2019-20. Grain and straw yield of rice grown after wheat in the same plot follows the order: incorporation>retention>burning>removal.

    An analytical study on impact of WTO on agricultural trade in India
    (CCSHAU, Hisar, 2019-12) Kavita; Mehta, V P
    The study on “An analytical study on impact of WTO on agricultural trade in India” was done with the following objectives: (1) To study the trends of agricultural trade in India during Pre and Post-WTO regime (2) To compute the terms of trade in Indian agriculture (3) To examine the comparative advantage in India‟s agricultural trade (4) To study the instability of India‟s agricultural trade and suggest appropriate policy measures for improving the agricultural trade. The present study was based on secondary data collected from the various published sources, viz., various issues of hand book of RBI, FAO Trade year Book, Statistical Abstract in India, indiastat.com, FAOSTAT etc. The data were grouped into two periods (Pre-WTO and Post-WTO) depending upon the formation of world trade organization and its effect on export and import of agricultural sector, Period-I is characterized by impact of world trade organization on agricultural trade before formation of world trade organization and ranged from 1975 to1994 and Period-II ranged from 1995 to 2015 which is the Post-WTO period. India became a member of WTO on 1st January 1995 and it was the first multilateral agreement, meant to curb unfair practices in agricultural trade and set off the process of reforms in the agricultural sector. A decreasing trend was observed in agricultural export share of India in world‟s agricultural export during pre- WTO period and an increasing trend during post-WTO period whereas India‟s import share showed reverse trend. Agricultural export share in national export has been showing decreasing trend during pre as well as post-WTO period. Similarly agricultural import share in national import has been showing decreasing trend during pre and post-WTO period. Terms of trade of agricultural sector of India in quantity as well as value terms were decline during pre-WTO period and intensified during post-WTO period. Indian agricultural sector shows trade surplus during pre-WTO period as well as post-WTO period. India has gained comparative advantage in export of cereals, pulses, spices and cash crops and comparative disadvantage in oilseeds, dairy products and eggs, meat and meat preparation whereas mixed result observed in case of fruits and vegetables export. Agricultural trade and national trade were stable during pre-WTO period as compared to post-WTO period.

    Evaluation of wheat species for heat tolerance related morpho-physiological traits
    (CCSHAU, 2015) Kavita; Munjal, Renu
    Twenty non-cultivated and cultivated genotypes belonging Triticum aestivum, Triticum durum, Triticum dicoccum and Synthetic were evaluated for Cell membrane stability (CMS), Canopy temperature (CT), SPAD chlorophyll content, Chlorophyll fluorescence, heat susceptibility index (HSI), and grain yield under normal and heat stress conditions for two years (2012-13 & 2013-14). The current study was aimed at the characterization of physiological traits in wheat species for their heat tolerance and its analysis in relation to yield components which confer yield stability at the three ploidy levels - diploid, tetraploid and hexaploid wheat species. Mean sum of squares due to years, environments, genotypes and majority of the interaction effects were significant for almost all of the traits. This suggested the variable responses of genotypes, over the environments and years for the traits under consideration with in each ploidy group for heat tolerance. Correlation coefficients revealed that CMS was the most important trait followed by CT because the genotype having high CMS also had low CT and high grain yield under heat stress. Triticum dicoccum conferred the productive and adaptive advantages as it combined high yield and stability compared to Triticum durum, Synthetic Wheat and Triticum aestivum respectively. Since wide variation for heat tolerance of physiological traits are available among the wheat species, these species can be used for improving specific yield components of cultivated wheat.

    Characterization of seed sources of sissoo (Dalbergia sissoo roxb.) using molecular markers
    (CCSHAU, 2015) Kavita; Bimlendra Kumari
    The ecological and economic importance of Dalbergia sissoo and declination of its population in its natural habitat promoted the present study. Based on desired economically important characters, seed sources were selected from nine provenances covering different agro-ecological regions of Haryana. The progeny testing was done for one year in the nursery of Forestry department, CCS H.A.U., Hisar. Genetic diversity was evaluated by using RAPD markers. Significant variations were observed among the provenances as well as agroecological regions for all the plus tree characters viz., total height, diameter at breast height, clear bole height, crown spread and straightness. Correlation among most of the characters was also significant with maximum value 0.923 between total height and diameter at breast height. Variations among morphological characters of pods and seeds were significant. High heritability with high genetic advance was observed for pod and seed weight character. The maximum genotypic and phenotypic correlation (0.598 and 0.519) was observed between seeds per pod and 100 pod weight, and seed length and 100 seed weight, respectively. Ample genetic variation was also observed for germination percentage, seedling height, collar diameter, number of branches per seedling, height of first branch, root length, fresh weight and dry weight among the progenies of the selected plus trees. Fresh weight and dry weight characters were found highly significantly correlated, followed by root length and total height. Among all the progenies, the progeny of Ambala seed sources at a stage of six month and Hisar progenies at 12 month age was found outstanding. Genetic diversity among the plus tree progenies assessed with the help of 60 RAPD primers displayed the values of genetic similarity coefficient ranging from 0.49 to 0.81, which indicated a broad genetic base of Dalbergia sissoo in selected area of Haryana state.
