    Nutrition transition as affected by mass media: A study on youth of Haryana
    (2013) Mehlawat, Urvashi; Khetarpaul, Neelam
    The present study was undertaken in Gurgaon district of Haryana state. From D.S.D. Govt. College and DPG Institute of Technology and Management (Private College) a total of 200 (100 students from each college) college going students of 17-21 year age were selected randomly for the study. Information regarding mass media interaction, eating habits, food frequency and food disorders was collected. Anthropometric measurements, dietary intake (24-hour recall) and dietary diversity scores were used to assess the nutritional status of the college going students. Most preferred sources of information for respondents were TV (82.5%) followed by mobile phones (79.5%), newspaper (52%), internet (38%), radio/FM (27%) in descending order. More girls (39%) were watching television for 2- 3 hours daily as compared to boys (21%) and more girls (46%) preferred watching daily soaps than boys (24%) who were watching more of sports/athletics programs. Most of the respondents (63%) were satisfied with their body physique/figure. More number of girls (32%) wanted to lose weight than boys (17%). More girls (38%) than boys (28%) skipped meals after watching/ reading a fashion programme/article/magazine. Samosa/bread pakora (39.5%), fresh juice (30%) and tea/coffee (28%) were the foods taken very oftenly by the respondents; meals taken outside rarely included fruits/vegetables/juices (52%) and soft drinks/fast food (43.5%) and a higher percentage of respondents (49.5%) took one meal outside home daily. The intakes of pulses, roots & tubers, other vegetables, GLV’s and sugar & jaggery were significantly lower among girls and boys of 17-18 years except for boys (18-21Y) who had higher intake of roots & tuber. Cereal intakes of both girls and boys were higher than the RDI. Iron intake was significantly (p<0.05) lower in girls and boys of 17-21 years. Girls (17-18Y) had significantly (p<0.05) lower intakes of folic acid while boys (18-21Y) consumed significantly lower amount of riboflavin. Mean dietary diversity score was 5.7. All of the students consumed items from the four food groups’ viz. starchy staples, all other fruits and vegetables and vitamin-C rich fruits. Mean weight, waist circumference and waist-to-hip ratio of girls and mean waist circumference of boys of 17-21 years were significantly lower than their respective reference values. In the overweight category, there were only 9 per cent girls and 4 per cent boys while only 2 per cent girls were found to be obese and as per body fat per cent there were 14 per cent girls and 13 per cent boys who were overweight. Obesity was prevalent among girls (32%) and boys (22%).

    Bio-efficacy of bacterial parasite, pasteuria penetrans (ex thorne) sayre & starr application as seed coating and nursery soil treatment against root-knot nematodes, meloidogyne spp
    (CCSHAU, 2013) Vikaram; Walia, R. K.
    Four species of Meloidogyne i.e., M. arenaria, M. graminicola, M. incognita and M. javanica were tested for Pasteuria penetrans endospore adherence and development. After 48 hrs, endospore adherance was least in case of M. graminicola and M. arenaria but significantly more in M. javanica and M. incognita. This strain of P. penetrans did not infect M. graminicola, however, development on the other three species was very efficient, and the infection varied from 70-90%. Three experiments were conducted in summer, kharif and winter seasons using cotton, okra and chickpea to test the efficacy of P. penetrans as seed treatment against M. javanica. The results on cotton and chickpea were not significant. However, only during kharif season (mean maximum and minimum temperatures of 34.5° and 26.4° C, respectively) on okra, P. penetrans used @ 4 and 5% as seed coat resulted in significant reduction in root galling, egg production and infection of females. Efficacy of P. penetrans application as nursery soil treatment was tested in two seasons. In kharif season (mean maximum temperature of 34.5° C and the minimum temperature of 26.4° C) higher doses of P. penetrans (8 x 104 and 10 x 104 endospores per g soil) resulted in better seedling germination and improved fresh weight of seedlings. All the doses of P. penetrans caused significant reduction in galling and were also equally effective in suppressing nematode egg production. The two highest doses of 8 x 104 and 10 x 104 caused up to 70% nematode infection. Similar experiment during winter season did not produce any tangible results.

    Effect of seasonal climatic variability on wheat productivity in western agroclimatic zone of Haryana
    (CCSHAU, 2013) Kamlesh Kumar; Surender Singh
    The present scientific investigation entitled ‘Effect of seasonal climatic variability on wheat productivity in western agroclimatic zone of Haryana’ was undertaken to work out the climatic variability and trends at two locations in western agroclimatic zone of Haryana viz., Hisar and Sirsa and to have an idea of the probable impact of future trend scenarios for productivity of wheat in the zone (main wheat growing region of Haryana) using CERES-Wheat model. Historical data (1977-2008) on weather and wheat productivity for above two locations were collected and considered or the study. Analysis of data indicated more variations in maximum temperature during the recent period (1997-08) with comparatively higher values of CV at Hisar (2.77%) and Sirsa (2.68%). Summer season’s maximum temperatures have also shown more fluctuations with higher CV values both at Hisar (14.55%) and Sirsa (15.87%). The mean minimum temperature (9.1 ºC) observed at Hisar during rabi season was lower than that observed at Sirsa (9.9ºC). In the recent past (1997-08) period, both maximum and minimum temperatures exhibited increasing trend in rabi season both at Hisar and Sirsa. However, the magnitude of increase in maximum (0.188ºC) and minimum temperatures (0.053ºC) at Hisar was more when compared with (0.102ºC) and (0.031ºC) at Sirsa, respectively. During rabi season, rainfall occurrence showed increasing trend both at Hisar and Sirsa during the entire period under study. However, in the recent past (1997-08), the rainfall activities during rabi season decreased @ 5.673 mm and 2.208 mm per year at Hisar and Sirsa, respectively. Sirsa received more rainfall (75.6 mm) than Hisar (54.9 mm) in rabi season during the entire period of study. The periodic rainfall ranged between 63.3 to 87.7 mm at Sirsa and 47.4 to 60.8 mm at Hisar in rabi season. CERES-Wheat model simulations with an increase in maximum temperature by 1.0ºC over normal value exhibited positive effect on wheat productivity coupled with elevated CO2 concentration upto 100 ppm above the 330 ppm CO2 level at both the locations projected by CERES-Wheat model. The model projected a maximum yield loss of 18.2 per cent at Hisar and 16.3 per cent at Sirsa with 2.5ºC increment above normal both in maximum and minimum temperature. During rabi season, both rainfall and solar radiation had positive effect on wheat productivity at both the locations. The model predicted yield reduction by 0.89, 1.97, 4.12 and 6.78 per cent from mean simulated yield, due to anticipated decrease in rainfall by 15, 30, 40 and 50 mm at Hisar during rabi season.

    Efficacy of imazethapyr + imazamox (Ready Mix) in cluster bean and its residual effect on mustard in two texturally different soils
    (CCSHAU, 2013) Sangwan, Meenakshi; Satyavan
    An experiment was carried out at two locations, CCS HAU Hisar and famer’s field, Kheri Batter, Bhiwani. In the study, efficacy and phytotoxicity of different herbicide in cluster bean during kharif of 2013 and their carryover effect on mustard crop was observed. PRE application of pendimethalin + imazethapyr (Ready and tank mixture) and pendimethalin although provided 85-90 % control of weeds upto 30 DAS, but at 60 DAS, due to new emergence of weeds, visual control of weeds reduced to 65 % in pendimethalin, but other two treatments provided 85% weed control upto 60 DAS without any phytotoxic effect on cluster bean. At 60 DAS, highest weed control (88%) was recorded under POE application of imazethapyr 100 g/ha fb propaquizafop 62.5 g/ha which was at par with pendimethalin + imazethapyr (Ready and tank mixture) and imazethapyr + imazamox (Odyssey) 70 g/ha fb propaquizafop 62.5 g/ha, but the efficacy of Odyssey was lower under Hisar conditions due to heavy infestation of T. portulacastrum as compared to other herbicidal treatments. No crop phytotoxicity was observed under PRE applied herbicides. Only POE herbicides showed crop phytotoxicity and growth suppression. At initial stages, higher rates of imazethapyr + imazamox and imazethapyr applied POE resulted in chlorosis of leaves, suppression of growth and the plant height, though plants recovered within 2 weeks and no injury was observed at later stages. Highest seed yield, maximum net return and B-C ratio was obtained under POE imazethapyr 100 g/ha fb propaquizafop 62.5 g/ha, and pendimethalin 0.5 kg + imazethapyr 50 g/ha (tank mixture) as PRE, but both were statistically similar to each other and similar to pendimethalin + imazethapyr (RM) 1.0 kg/ha as PRE & imazethapyr + imazamox 70 g/ha fb propaquizafop 62.5 g/ha as POE at location Kheri Batter, but at Hisar location pendimethalin + imazethapyr (ready and tank mixture) provided maximum net return and B-C ratio. There was no carry over effect of different herbicides used in cluster bean on succeeding mustard crop, probably due to microbial degradation, higher temperature and leaching of herbicides because of high moisture during the time of herbicide application and planting of mustard in 2013-14.

    Phenotyping and molecular marker analysis of selected HKR47 x MAS26 (aerobic) F2 rice progenies
    (CCSHAU, 2013) Usha Rani; Jain, R.K.
    Experiments were conducted to evaluate segregating HKR47 x MAS26 (aerobic) F3 plants for various physio-morphological and root traits and allelic diversity for 7 microsatellite markers linked to the root traits. In HKR47xMAS26 F3 plants enormous variation was observed for plant height, panicle length, and number of tillers per plant, seeds per panicle, percent seed setting, root length, root thickness, root volume, fresh and dry root weight, 1000 grain weight, grain length/breadth ratio and yield per plant. The NTSYS-pc UPGMA cluster tree analysis led to the grouping of 46 F3 plants in two major groups at a similarity coefficient of 0.5. All the 46 F3 plants clustered in two major groups at the similarity coefficient of 0.50. Major group I consisted of HKR47 and 16 F3 plants while the major group II had MAS26 and 30 F3 plants. A number of promising F3 plants have been selected, which had higher grain yield, root length and biomass greater than the parental rice varieties (MAS26 and HKR47)for further progeny analysis.

    Development and evaluation of sugarcane trash chopper cum spreader
    (CCSHAU, 2013) Malik, Nadeem Ahmad; Anil Kumar
    In India sugarcane is an important commercial crop occupying about 4.4 million hectares of land with an annual sugarcane produce of 283 million tonnes. One of the biggest problems faced by the sugarcane growers is the disposal of trash. To overcome this problem the farmers usually burn sugarcane trash which causes harmful impact on the environment and leads to loss of nutrients. On the other hand, trash mulching has been found to be advantageous in increasing the soil fertility and conservation of soil moisture. However, the trash size in the field is of large size so it needs to be reduced in size to increasing the composting process. Keeping in view the above problems, a prototype of sugarcane trash chopper cum spreader was developed to chop the trash and spread it to the field uniformly. The dimensions of the prototype were 4100 mm x 1840 mm x 1910 mm. The machine was tested at five levels of moisture content viz. M1, M2, M3, M4, M5 having values 18.75%, 16.54%, 15.15%, 13.19% and 13.13% (db) respectively and four different velocities V1, V2, V3, V4 having corresponding values of 2.76, 2.8, 2.9 and 3.2 km h -1 . The maximum shredding capacity of the machine was found to be 4.31 t h -1 at moisture content of 13.13 % and forward speed of 2.9 km h -1 with maximum shredding efficiency of 90.4 per cent. The prototype chopped up sugarcane trash of about 4 to 12 cm length. The average field capacity of the machine was found out to be 0.40 ha/h with efficiency of 78.2 per cent. The uniformity of trash spreading varied from 0.90-0.95. The cost of operation of the machine was found to be Rs. 786/h. the B:C ration was 1.5 and payback period of the machine was 1.3 year if operated for 250 hours per year. The break-even point of machine was 17.7 ha.

    Storage studies in potato (Solanum tuberosum) under ambient conditions
    (CCSHAU, 2013) Archana; Rana, M.K.
    The present investigation entitled “Storage studies in potato (Solanum tuberosum L.) under ambient conditions” was carried out in Post-harvest Laboratory of the Department of Vegetable Sciences, CCS Haryana Agricultural University, Hisar during the year 2012. The three grades of potato tubers, i,e,, small, medium and large, of variety Kufri Badshah, Kufri Bahar, Kufri Pukhraj and Kufri Pushkar were packed in gunny bags in all the possible combinations under ambient conditions. The storage experiment was started on 9th March 2012 and ended on 9th June 2012. The observations were recorded on physiological loss in weight (%), decay loss on number and weight basis (%), sprout loss on number and weight basis (%), total loss (%), dry matter (%), specific gravity (%), starch content (%), nonreducing sugar (mg/100g), reducing sugars (mg/100 g), total sugars (mg/100 g), ascorbic acid (mg/100 g), phenol content (mg/100 g), black or hollow heart and general appearance of the tubers. The loss in weight of tubers due to physiological activities, decaying and sprouting increased with the increase in storage period and the loss was more in larger than smaller and medium tubers. Sprouting was 100% in Kufri Bahar with all possible combinations during storage. Dry matter content and specific gravity also increased with increasing storage period and both were more in larger tubers. There was a marked reduction in phenol, ascorbic acid and starch content of potato tubers during storage up to the end of the experiment. Phenol had the negative correlation, whereas, starch and ascorbic acid content had the positive correlation with the size of potato tubers. Reducing and total sugars decreased up to 45th day of storage, but thereafter, both increased up to the end of storage and were negatively correlated with size of the potato tubers, however, non-reducing sugar showed the reverse trend. Black or hollow heart was absent completely in all the possible treatments. So far general appearance of the tubers was concerned, the larger tubers shrivelled more and earlier than the medium and small sized tubers.

    Effect of medium constituents on micro propagation of sugarcane cultivar (cos-7717)
    (CCSHAU, 2013) Khichi, Poonam; Chowdhury, V. K.
    The experiments were conducted to study the effect of various media, gelling agents, carbon sources and photoperiods on in- vitro establishment, multiplication and rooting response in sugarcane cultivar (CoS-7717) using apical shoot tips as explants. For in- vitro establishment shoot tips were cultured on different media (Murashige and Skoog , Gamborg et al,White , Nitsch and Nitsch media) on BAP (0.5mg/l)+KIN(0.5mg/l) followed by establishment on MS medium supplemented with different c-source (Table Sugar, Sucrose , Fructose , Maltose , Glucose), gelling agents (Agar-Agar, Agarose , Gelerite , Guwargum , Isabgol) and varying photoperiods (16, 20 and 24h). Maximum number of shoots/explant (2±0) were reported on MS media fortified with BAP (0.5mg/l) + KIN(0.5mg/l), sucrose (30.0g/l) and agar-agar (8.0g/l) as a gelling agent using photoperiod of 16h. For in- vitro multiplication, the sprouted buds were transferred onto MS media containing different concentrations of growth regulators alone and in combination i.e. BAP, KIN, NAA, TDZ, SPM and PUT along with different carbon source (sugars), gelling agents and varying photoperiods (16, 20 and 24h). The maximum number of shoots (18.0±2.1) and shoot length (10.8±0.30cm) was reported on MS media fortified with BAP (0.25mg/l) +KIN (0.25mg/l) +NAA (0.1mg/l), supplemented with tablesugar (30.0g/l) and agar-agar(8.0g/l) under 16h of photoperiod. In vitro raised shoots produced 100% rooting on full strength MS medium supplemented with 5.0mg/l NAA and 50g/l sugar within 4 days of inoculation. Maximum survival (100%) of transplanted shoots was observed in Sand+ Soil+ Vermicompost (1:1:1) under green house conditions. Hardened plantlets were successfully transferred to the field conditions.

    Characterization of okra genotypes
    (CCSHAU, 2013) Sunil Kumar; Dhankhar, S.K.
    The present study entitled “Characterization of okra genotypes was carried out at the Research farm of Department of Vegetable Science, CCS HAU, Hisar during spring summer season of the year 2012 on the basis of morphological descriptors with the objective to identify key diagnostic characters of the genotypes. Observations were recorded for 37 morphological and six seed characters. Analysis of variance studies indicated significant differences among all the genotypes for all the characters under study. Highest mean fruit yield per plant was recorded for the genotype Hisar Naveen. Serration of leaf blade margin, vein colour, intensity of colour between vein, depth of lobing and petal base colour distinguished all the 20 genotypes by assigning them key diagnostic features that would certainly help the plant breeders, to use these diagnostic characters for trait specific use in breeding programme. Seed characters like Seed size, seed colour, seed shape and seed hairiness were also found key characters to differentiate the okra genotypes and will be helpful for seed agencies and in seed testing laboratories. The genotypes were also categorized on the basis of colour between veins, stem colour, number of nodes at first flowering, stem diameter (cm), plant height(cm), number of branches per plant, days to first flowering, petal colour, flower length (cm), fruit colour, fruit pubescence, shape of fruit apex, length of fruit (cm), fruit diameter (cm).
