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.

    Characterization and evaluation of wheat accessions for drought tolerance using morpho-physiological traits
    (CCSHAU, Hisar, 2020-08) Parul; Bishnoi, O.P
    The objectives of present investigation were to determine the genetic variability, estimation of association between grain yield and its component traits and among themselves to find out the correlation with morpho-physiological traits of 40 genotypes of wheat under drought and irrigated condition. Significant variability was observed among genotypes for all the traits under both conditions. Genotypes WH1127, DPW621-50 for grain yield while C306 and WH1164 for biological yield per plant were found promising under both environmental conditions. Grain yield per plant showed highly significant and positive correlation with biological yield per plant, harvest index, effective tillers per plant and 1000-grains weight. The path coefficient analysis revealed that harvest index showed highest direct and positive effect on grain yield per plant followed by biological yield per plant. Genotype IC529189 showed better expression for NDVI, C.T, SPAD under drought condition while under irrigated condition, maximum value for NDVI was shown by genotype IC529909 and for SPAD genotype IC529189. Based on SSI it was found that genotype EC609575, DT25, IC539518, IC529429 were more resistant to drought. Genotypes which resulted in the expression of higher grain yield would be selected.

    Mitigation of the moisture stress in forage sorghum through foliar application of silicon
    (CCSHAU,HiSAR, 2020-08) Parul; Goyal, Vinod
    The present investigations were conducted on forage sorghum to “identify the physio-biochemical mechanism of silicon in mitigation of low moisture stress”. Sorghum [Sorghum bicolor (L.) Moench] is fifth most important crop after wheat, rice, maize and barley around the world and is popularly known as Jowar. India is one of the largest growers of sorghum in the world. Sorghum is mainly grown for fodder, as a multi-cut, double-cut and single-cut crop, fodder and grain as dual purpose and for grain only. The summer/forage sorghum mainly suffers from moisture stress. In kharif (rainy) season also, the uncertainty of monsoon is the main cause of yield, as in some places irrigation facilities are not available. Silicon is an important micro nutrient and its application increases abiotic and biotic stress resistance in various crops. To explore the potential of this silicon (OSA) on forage sorghum for mitigation capability of moisture stress , a field experiment was conducted with different doses ( 1,2,3 & 4 ml/l) of silicon at two stages Panicle initiation (PI) , Panicle initiation and flag leaf initiation ( PI+FL) at Dry Land Research Farm CCS HAU, Hisar. The source of silicon used is orthosilicic acid (OSA). It was observed that it OSA helps in optimizing the efficiency of various physiological processes to sustain the crop under stress. The parameters studied includes normalized difference vegetative index, photosynthesis, assimilation rate, transpiration rate, chlorophyll, chlorophyll membrane stability, plant water relations and free radicals scavenging activity for dissecting the mechanism of stress tolerance. Significant results were seen with application of silicon as the plants treated with 2ml/l of OSA, showed best performance in both the stages (PI) & ( PI+FL), however the results were best when applied at ( PI+FL) stage. It was observed that treatment of 2ml/l of OSA exhibited higher biomass, plant height and leaf area, number of leaves per plant, panicle length and panicle weight, number of seeds per plant that ultimately resulted into better yields. It was also observed that the crop remain green for longer duration and showed seed setting that indicates some positive relation of OSA with crop growth. This increased stay green trait observed in forage sorghum under rainfed conditions is a desirable trait and this is probably the result of increased plant water content (RWC, WP, OP), that ultimately resulted into increased physiological efficiency under moisture stress. The better physiological efficiency is a contribution of increased photosynthesis, chlorophyll content, chlorophyll stability, assimilation rate, transpiration rate coupled with optimization of antioxidant enzymes that resulted into more stability in the cell membranes. Overall, our studies conclude that application of 2ml/l of OSA at PI+FL stage is the best treatment for forage sorghum grown in rainfed conditions.
