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 land use on soil properties, nutrient status and heavy metals in soils of district Rohtak
    (CCSHAU, 2018) Pankaj Kumar; Rohtas Kumar
    In order to study the effect of agriculture, horticulture and industrial land use on soil properties, nutrient status and heavy metals content in soils of Rohtak district. Soil (n=30), groundwater (n=20) and plant (n=10) samples were randomly collected from agriculture, horticulture and industrial land use. One profile sample (i.e. from 0-15 cm, 15-30 cm, 30-60 cm and 60-90 cm depth) was also separately collected from each of these land use. The pH of soils is neutral to alkaline in nature. The EC, OC and CaCO3 content was found higher in profile samples of industrial land use. The content of macronutrient (N, P, K and S) in profile samples was found higher under industrial land use and the content these elements decreases with increase in soil depth. The content of micronutrients (Zn, Fe, Mn and Cd) and heavy metals (Co, Cd, Pb and Cr) was also found higher in industrial land use and decreasing trend of micronutrients with soil depth was observed for Zn, Fe, Mn and Cd. The pH, EC and OC content of the surface soil samples varies from 7.20- 8.70, 0.01- 2.90 dSm-1 and 0.02- 0.90 % in samples collected from agriculture, horticulture and collected from industrial land use, respectively. The average concentration N, P and K was found in order: industrial land use > horticulture land use > agriculture land use. The average content of Zn, Fe, Mn, and Ni was found higher under industrial land use and low in horticulture whereas, the content of Ni was found similar in agriculture as well horticulture land use. The average content of heavy metals like Co, Cd, Pb and Cr was also found higher under the industrial land use. Analysis of groundwater samples collected from these different land uses shows that the average of EC, CO3 2-, Cl-, SO4 2-, B, Ca2+ and Mg2+ was found higher in samples from industrial land use than rest of the two land uses. In groundwater samples, the mean content of Zn, Cu, Fe, Mn, Ni (micronutrients) and Pb, Cr, Co, Cd (heavy metals) was found higher for industrial land use. The average content of P, K and S was found higher under industrial land use but N content was found higher in plant samples from horticulture land use.

    Nitrate distribution in soil profile and yield of cotton in relation to different levels of nitrogen
    (CCSHAU, 2007) Pankaj Kumar; Kapoor, A.K.
    The present investigation was undertaken to study the nitrate distribution in soil profile and yield of cotton in relation to different levels of nitrogen. To achieve the objectives, a field experiment was conducted in micro plots (2M×2M) at the research farm of CCSHAU, Hisar. Cotton crop was taken with seven treatments of nitrogen viz., 0, 34.50, 45.54, 34.50, 40.02, 34.50 and 11.04 g N per plot applied through urea and/or nitrate containing irrigation water. The experimental results showed that mean EC, Ca2+, Mg2+, Na+, K+, HCO3-, Cl-, SO42- concentration of the soil profile decreased after the harvest of the crop as compared to at the start of the experiment irrespective of treatments. The maximum NO3–N, 47.88 (Kg/ha) was observed in T3 treatment after first irrigation in 0-15 cm soil depth while the minimum NO3–N, 5.39 (Kg/ha) in T1 treatment in 30-45 cm depth after first irrigation. The depth distribution of NO3–N concentration of the soil profile was predicted using models i) LEACHM considering water flow equation of Addiscot, uptake, transformation of different forms of nitrogen, rate constants, other exchange processes and weather parameters and ii) Pal et al. 1990, considering initial NO3–N concentration of the soil profile and of the irrigation water, evaporation/ evapo-transpiration, rainfall and field capacity of the soil profile. The magnitude and the trend of the experimental and the simulated NO3 concentration of the soil profile after different irrigations and harvest of the crop showed a good agreement between the two by LEACHM model (r2= 0.92, a= -3.18 and b= 1.51) where as by the Pal et al. 1990 model, the agreement was not up to the mark. (r2= 0.45, a= 3.67 and b= 0.448). Crop removal of nitrogen was highest in T7 treatment (93.5 Kg N/ha) and lowest in T1 treatment (91.7 Kg N/ha), respectively. At sowing, the total nitrogen in the soil profile was 186.8 Kg N/ha (157 Kg NO3 /ha and 29.8 Kg NH4/ha) while at the time of harvest, the total nitrogen was highest in T3 (132.1 Kg N/ha) and lowest in T1 (64.6 Kg N/ha). The mean plant height value was found to be lowest (138.50 cm) under T1 and highest (167 cm) in T3 treatment. The highest mean number of bolls was observed in treatment T3 (33.50) and lowest treatment T1 (16). The highest and the lowest mean cotton yield of 389.50 and 225.75 gm/plot were obtained under treatments T3 and T1, respectively.
