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.

    Impact of biochar and organic manures on soil properties and wheat yield
    (CCSHAU, Hisar, 2023-09) Deepak Kumar; Chaudhary, Kautilya
    A field experiment entitled “Impact of biochar and organic manures on soil properties and wheat yield” was carried at research farm, Department of Soil Science, CCSHAU, Hisar Haryana. The location of experimental site was 29o16’N latitude and 75o7’E longitude in the North-West part of India. The objective of this study to evaluate the impact of biochar and organic manures in enhancing the yield of wheat and soil properties. The experiment was designed with seven treatments comprising of control + RDF, 10 t/ha FYM + RDF, 5 t/ha vermicompost + RDF, 2.5 t/ha biochar + RDF, 5 t/ha biochar + RDF, 10 t/ha biochar + RDF and absolute control with three replications in a randomized block design by keeping net plot size 2.0 m x 2.0 m and row spacing of 20 cm. The observations were noted for fifteen parameters pertaining to the physical, chemical and microbiological properties of soil including yield attributes of wheat crop. The result showed that physical properties like moisture at -33 kPa and -1500 kPa (0-15cm) (4.5 cm h-1) and soil moisture at different intervals of times (14.45 and 8.54 %) was found maximum in treatment 10 t/ha biochar + RDF, while bulk density (1.38 mg m-3) was noted minimum in same treatment. In case of chemical properties of soil treatment 10 t/ha biochar + RDF reported maximum electrical conductivity (0.44 dSm-1), available NPK (126.50, 20.6, 380.4 kg ha-1), available micronutrients {Zn (1.91 mg kg-1), Cu (1.55 mg kg-1), Fe (10.75 mg kg-1) and Mn (3.80 mg kg-1)}, However maximum organic carbon recorded in treatment consisting 10 t/ha FYM + RDF and microbiological properties like microbial count (CFU/g soil) of bacteria 32.18 x 106 and actinomycetes (27.82 x 105), soil microbial activity of Dehydrogenase 119 ug TPF g-1 24 h-1, Urease (69.48 ug N g-1 soil h-1) and Alkaline phosphatase (208.95 ug PNP released g-1 soil h- 1) and microbial biomass carbon (808.77 mg kg-1) was found maximum in treatment 10 t/ha biochar + RDF, while minimum values were recorded in absolute control. The data recorded on yield attributes such as grain yield (5300 kg ha-1), straw yield (10675 kg ha-1), test weight (42.8 g) and harvest index (33.18 %) were found maximum in treatment 10 t/ha biochar + RDF. In economic analysis treatment 5 t/ha biochar + RDF was found practically more feasible with a net return (27825 Rs/ha) and benefit cost ratio (1.36).

    Biology, population dynamics and management of fall armyworm, Spodoptera frugiperda (J.E. Smith) on maize
    (CCSHAU, Hisar, 2021-09) Deepak Kumar; Maha Singh
    The present investigation entitled, “Biology, population dynamics and management of fall armyworm, Spodoptera frugiperda (J.E. Smith) on maize” was carried out at Research Farm and laboratories, Department of Entomology, CCS Haryana Agricultural University, Hisar and Research Farm CCS Haryana Agricultural University Regional Research Station, Uchani, Karnal during Kharif, 2020. The biology of S. frugiperda was observed at four different temperatures viz., at room temperature, 15°C, 25°C and 35°C, respectively. The average fecundity of S. frugiperda was 1110.6, 714.8, 1303.9 and 1013.1 eggs/female at room temperature, 15°C, 25°C and 35°C, respectively. Egg hatchability was observed as 93.3, 74.9, 83.5 and 92.5 per cent whereas incubation period as 2.68, 6.08, 3.24, 2.80 days at room temperature, 15°C, 25°C and 35°C, respectively. Average larval period was 15.44, 32.97, 19.96 and 15.09 days whereas larval survival as 85.6, 58.8, 62.4 and 84.3 per cent at room temperature, 15°C, 25°C and 35°C, respectively. Pupal period was noticed as 7.78, 25.63, 9.28 and 7.42 days whereas the adult emergence as 64.2, 52.0, 63.0 and 68.5 per cent at room temperature, 15°C, 25°C and 35°C, respectively. Total life cycle of females was observed as 35.13, 79.33, 45.19 and 34.73 days while those of males as 33.24, 77.05, 42.71 and 32.46 days at room temperature, 15°C, 25°C and 35°C, respectively. Studied on population dynamics of S. frugiperda revealed that larval population prevailed from 28th SMW to 40th SMW. Its peak was observed during the 33th SMW with a mean population of 4.93 larvae per plant. The average plant infestation was observed from 28th SMW to 40th SMW (second week of July to first week of October) with a maximum of 79.1 per cent during 40th SMW. Larval population had a significant positive correlation with evening relative humidity (r = 0.652) and significant negative correlation with sun shine hours (r = -0.634) whereas per cent plant infestation indicated a non-significant correlation with all the weather entities. During the study period, three hymenopteran larval parasitoids (Chelonus sp., Cotesia sp., Campoletis sp) were also observed. Studies on screening of maize genotypes against S. frugiperda indicated that amongst the 55 maize genotypes, HM 10 recorded lowest leaf injury (4.45 score), while HKI 1348-6-2 recorded highest leaf injury (8.85 score). Five genotypes (HKI 1105, HKI 139, HKI 193-2, HKI 1011 and HM 10) were categorized as partially resistant (leaf injury score: 4.0 to 5.99), 20 genotypes as susceptible (leaf injury score: 6.0 to 7.99) and 30 genotypes as highly susceptible (leaf injury score: 8.0 to 9.00). Studies on effect of date of sowing on incidence of S. frugiperda indicated that plant infestation and larval population was observed minimum when crop was sown during last week of June while infestation and larval population gradually increased as date of sowing is delayed.
