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.

    Evaluation of plant growth promoting actinomycetes on chickpea (Cicer arietinum L.)
    (CCSHAU, 2019) Kavita Rani; Leela Wati
    Chickpea is the second most important cold season food legume grown globally on a very wide area. However, global yields of chickpea have been relatively stagnant for the last two decades due to unpredictable climatic changes, incidence of diseases and extensive application of chemical fertilizers and pesticides. Actinomycetes are one of the major components of rhizosphere microbial population and are useful in soil nutrient cycling as well as plant growth-promotion. Since last few years, studies on beneficial traits of actinomycetes regarding plant growth promotion and biocontrol activities had opened new avenues for their applications in sustainable agriculture. In the present investigation, total 40 (AK1-AK40) actinomycete isolates were retrieved from different soil samples and chickpea nodules collected from CCS Haryana Agricultural University, Hisar farms. All the isolates were assessed for different plant growth promoting traits including IAA production, P solubilization (P-SI), Zn solubilization (Zn-SI), siderophore production, HCN production, salt tolerance, biocontrol potential against F. oxysporum, ACC utilization and ammonia excretion. Based on the results of various PGP traits, isolate AK3 with high P-SI (2.78) and Zn-SI (3.92); AK6 with high HCN production; AK11 with good P-SI (2.70) and Zn-SI (3.27) and AK34 with high IAA production (20.95μg ml-1) were evaluated for growth promotion of chickpea under pot culture conditions. Isolate AK3 found promising in terms of nodulation, growth and yield parameters under pot culture conditions was evaluated on chickpea variety HC-5 under field conditions (during 2017-2018). Coinoculation of AK3 along with Mesorhizobium 1233 was beneficial for plant growth and yield of chickpea. The promising actinomycete isolate AK3, identified as Streptomyces griseoruber on the basis of partial 16S rDNA sequencing, can be further tested on different locations for use as biofertilizer.

    Stability analysis for Yield and Quality Components in Transplanted and Direct Seeded Rice (Oryza sativa L.)
    (CCSHAU, 2019) Kavita Rani; Khushi Ram
    The present study entitled “Stability analysis for yield and quality components in transplanted and direct seeded rice (Oryza sativa L.)” was undertaken to estimate genetic parameters and to study stability of various trait. The material for the present investigation comprised of thirty genotypes (15 scented and 15 non-scented) grown in twelve environment under two production system i.e., direct seeded and transplanted rice were carried out during the kharif seasons in the year 2016 and 2017 in a randomized block design (RBD) at Rice Research Station, Kaul (Kaithal). The observations on five randomly selected plants from each replication in each environment were recorded for days 50 % flowering, days to maturity, plant height (cm), number of tillers per plant, panicle length (cm), number of grains per panicle, thousand grain weight (g), biological yield per plant (g), grain yield per plant (g), harvest index (%). For physical quality traits such as hulling (%), milling (%) and head rice recovery (%), a sample of 25 g was used. Cooking quality traits such as kernel length before cooking, kernel breadth before cooking, length breadth ratio before cooking, kernel length after cooking, kernel breadth after cooking, length breadth ratio after cooking and elongation ratio data were taken on ten polished grains for each quality traits. On the basis of mean performance the genotype IR 93928-195-2-1-1, IR 93835-90-3-2-1, HKR 48 and HKR 12-411 were found for early flowering and maturity and grain yield were almost similar in DSR, TPR and pooled over the environments. High estimates of PCV and GCV were recorded for number of tillers per plant, number of grains per panicle, grain yield per plant, harvest index and elongation. High heritability estimates alongwith high genetic advance as percent of mean was observed for number of tillers per plant, number of grains per panicle, days to flowering, harvest index, elongation ratio. Grain yield per plant had moderate heritability coupled with high genetic advance as per cent of mean. The genotypes HKR 12-1, HKR 07-147, IR 91648-B-89-B-14-2, IR 93928-195-2-1-1, IR 91648-B-2-38-B-1-2 and PUSA 1718-14-2-150 were found below average stable for grain yield in direct seeded rice. The genotype HKR 07-147 and IR 91648-B-2-38-B-1-2 were found suitable for grain yield for favourable environment under direct seeded, transplanted and pooled over the environments. The estimation of environmental index revealed that environment ten (E10) was found most suitable for panicle length, grain yield per plant, biological yield per plant, number of grains per panicle, hulling (%) and kernel length before cooking under direct seeded, transplanted rice and pooled over the environments.
