Abstract: The field experiment was conducted to study the effect of plant growth regulators and pinching for increasing growth and quality of African marigold. An experiment was laid out in Factorial Randamized Block Design along with 14 treatments and replicated thrice. Two F1 hybrids namely V1 Gold Benz tall and V2 Maxima yellow were taken for the study comprising GA3 @ 50, 100 and 150ppm, NAA @ 50, 100 and 150ppm, MH @ 250, 500 and 750ppm, Alar @ 200, 400 and 600ppm and pinching with untreated control. Among the varieties V1 recorded the tallest plants (78.59cm), maximum number of leaves and leaf area (324.62 and 90.91cm2), highest flower diameter, stalk length, single flower weight and flower volume (8.31cm, 8.11cm, 11.22g and 113.96cc), whereas V2 produced the shortest plants (35.58cm), minimum number of leaves and leaf area (282.97 and 85.00 cm2), flower diameter, stalk length, single flower weight and flower volume (7.94cm, 6.99cm, 10.11g and 103.15cc). But V2 registered the highest number of laterals plant-1 (12.85) followed by V1 observed the least number of laterals plant-1 12.53. The plant sprayed with of GA3 @ 150ppm was found most effective as it registered the maximum plant height (70.44cm), number of laterals plant-1 (16.13) number of leaves plant-1 (383.76), leaf area (113.51 cm2) and diameter of fully opened flower (9.64cm), length of flower stalk (9.79cm), single flower weight (12.81) and flower volume (130.11) and it was followed by GA3 @ 100ppm.

Abstract: Hepatitis B virus (HBV) infection affects millions of people worldwide and about a half million people die every year. It is a serious liver disease, caused by hepatitis B virus. The disease is transmitted through human body fluids such as blood and serum.The objective of the study is to identify the optimal age for revaccination.All the subjectswere received vaccination under vaccination project at childhood age. Serum was separated and the titre of anti-HBsAg was estimated using quantitative method of double antibody sandwich-ELISA.There were 100 subject included in the study. Seroprotective rate decreased significantly with increasing time from last vaccination due to decrease in anti-HBsAg titre over time.Hepatitis B vaccination has been accepted to induce the protective antibody level after the complete dose of vaccination. Anti-HBsAg concentrations declined over time among studied subjects successfully immunized with HB vaccine starting atbirth. The study shows that male were more prone to hepatitis B infection as compare to femaleThe correlation analysis revealed a highly significant negative correlation (r = 0.92, t= 9.95, p<0.05) between different age groups and conc. of Anti HBsAg of sera samples of selected individuals. HB vaccine-boosting could be advised for high risk subjects including adult health care workers and children at endemic area at twenty years intervals.

Abstract: Endosulfan is an important chlorinated hydrocarbon pesticide used against insect pest for a number of diverse applications and more specifically used in poultry farming in India for the control of termites in chicken houses. Twenty White Leghorn birds were given Endosulfan in drinking water @ 30 ppm/bird/day (no observable effect level dose) for a period of three months to investigate the physical and productive changes in the birds after limited oral administration of Endosulfan insecticide. Production performance, serum calcium and phosphorus levels of layer birds were estimated at 15 days intervals. There was significant reduction of 22.81% in average egg production and 8.18% decrease in percent hatchability on total egg set basis, however, average egg weight was reduced by 3.08%, fertility was reduced by 4.94% and percent hatchability on fertile eggs set basis was mildly decreased by 4.03% due to exposure to endosulfan. The calcium and phosphorus levels were progressively reduced from 15-90 days of treatment. The level of phosphorus (26.32-35.19%) was more severely affected than that of the calcium levels (13.92-26.68%) in the endosulfan treated group as compared to control. Present investigation reveals clear productivity losses due to presence of this insecticide warranting need of removing the chemical insecticide from the life cycle of layers.

Abstract: An experiment was conducted at Krishi Vigyan Kendra, Basti (UP) with two high yielding rice varieties to standardize the System of Rice Intensification (SRI) method including the age of seedling and variable spacing. The SRI standardized package was compared with the conventional production system of rice at farmer’s field. Maximum grain yield (66.80 q/ha) along with all the contributing traits i.e. plant height (130.0 cm), root depth (30.0 cm), root spread (20.66 cm), root biomass (16.75 g/m²), number of tillers (36), spikes (27), spike length (32.66 cm), grains/spike (285), test weight (37.3 g) and grain yield (66.80 q/ha) were recorded in variety NDR-359 with 10 days of seedling age planted at 25 X 25 cm spacing. Similar trend of observations were also recorded through this spacing in case of variety PNR-113, where, plant height (120.33 cm), root depth (27.0 cm), root spread (16.66 cm), root biomass (16.80 g/m²), number of tillers (33), spikes (26), spike length (28.60 cm), number of grains/spike (282), test weight (35.25 g) and grain yield (65.70 q/ha) witnessed. At farmer’s field in demonstration trial 14.44 per cent increase in grain yield through SRI practice was remarkable. It is an eco-friendly approach because it helps in resource conservation owing to its need of less exploitation of ground water, no use of any weedicide and minimum use of other hazardous chemicals (insecticide/ fungicide).

Abstract: Eight tobacco inbred lines were crossed in all possible combinations excluding their reciprocals. F1s of thesecrosses, their parents and one check variety MRGTH 1 were evaluated in RBD with three replications. The extent and magnitude of various heterotic effects varied from cross to cross and character to character. However, greater amount of relative heterosis, heterobeltiosis and standard heterosis were observed for cured leaf yield per plant and important yield component attributes. The crosses, which exhibited higher estimates of relative heterosis for cured leaf yield were ABD 10 x Red Russian (44.96%), ABT 10 x Red Russian (23.07%) and GT 9 x GT 7(18.91%); whereas, the superior crosses in respect to heterobeltiosis were ABD 10 x Red Russian (21.92%), GT 9 x GT 7 (17.16%)and ABD101 x ABD 111 (16.55%); while, the hybrids ABD 101 x ABD 111(37.46%), ABD 111 x GT 7 (21.40%) and ABD 101 x GT 7 (19.78%)depicted significant and positive heterotic effects for standardheterosis. On the basis of per se performance and estimates of heterosis, hybrids ABD 101 x ABD 111, ABD 111 x GT 7, ABD101 x GT 7 and GT 9 x GT 7 were found to be most promising for cured leaf yield and other desirable traits; hence could be further evaluated to exploit the heterosis or utilize in future breeding program to obtain desirable segregants for the development of superior genotypes.

Abstract: The present investigation was undertaken in cold desert of Spiti Valley, Himachal Pradesh to assess morphological, biochemical and leaf proximate composition diversity of Hippophae rhamnoides populations. Nine major gene pool areas and three growing conditions within major gene pool areas, selected for the study showed wide variation among different morphological, biochemical and leaf proximate compositions traits. On the basis of results, eventually, it may be concluded that GPA-4 (Schilling) was superior than other major gene pool areas for leaf proximate compositions with highest crude fibre (18.22%), crude protein (21.60%) and total ash (11.38%) and GPA-3(Sheigo) for fruits (18.54 g), seed (2.99 g) and biochemical parameters i.e. juice content (80.05 %), Total sugar content (5.94%) and ascorbic acid ( 595.13 mg/100 gm) among different major gene pool areas. And, for fodder purpose, GPA-4 (Schilling) and for fruits quality parameters, GPA-3(Sheigo) major gene pool area, are the best for further utilisation. Over all, GC-3 (Crop land) was found superior for all morphological traits among different growing conditions under different major gene pool areas. Based on the morphological, biochemical and leaf proximate compositions traits observations, it was evident that large diversity exists in naturally growing populations of Hippophae rhamnoides in the Spiti Valley of Himachal Pradesh, and thus morphogenetic variation can be exploited for the further selection of suitable genotypes to accelerate the domestication process of this important species.

Abstract: The aim of our study was to determine changes in enzyme activity (Ascorbic acid oxidase and catalase) and ascorbic acid content after the application of pesticides thiodicarb, spinosad, profenophos and chlorantraniliprole at recommended dose. The experiments involved two kharif (2013-14 and 14-15) and two rabi (2013-14 and 14-15 season. The four different varieties of brinjal ( Malapur local-V1, Kalpataru-V2, Manjula-V3, Manjari-V4) screened in experiments. The effect of pesticides belonging to different chemical groups i.e., thiodicarb (carbamate), spinosad (naturalyte bacterial origin pesticide), profenophos (organophosphates), and chlorantraniliprole (anthranilic diamide) varied due its persistence and half life. Ascorbic acid content in brinjal fresh fruits differ significantly in pesticide treatments at all the stages. Data recorded for ascorbic acid content showed maximum in V4P3 (5.12-5.30 mg 100 g-1) in both the seasons. On the contrary, however, it decreased with 115 to 125 DAT, the maximumAA content declined in non-sprayed control (3.71-2.22 mg 100 g-1).Among interactions, AAO activity did not differed significantly at 90 DAT during kharif. The activity of ascorbic acid oxidase indicated maximum (15.65 unit min-1 g-1)) in non-sprayed control compared to sprayed treatment.The minimum activity recorded in V4P3 (7.30 unit min-1 g-1) might be due to AAO response to biotic stress. The effects on CAT activity was dependent on pesticide treatments showing highest value (30.63 units g-1) in variety Manjari treated with profenophos after 4 days of spraying and their compounds accumulated in the fruits creating chemical stress in plants.

Abstract: The present clinico-epidemiological investigation of 120 dogs at the Teaching Veterinary Clinical Complex (TVCC), C.V.Sc. and A.H., OUAT, Bhubaneswar showing the symptoms of haemorrhagic gastro enteritis was made against CPV infection through Polymerase Chain Reaction (PCR)& KIT test method based on the basis of breeds, age and sex. The young pups between age groups 4-12 months were found mostly susceptible to Canine parvo viral haemorrhagic gastroenteritis as compared to other age groups. Further, the male dogs were found to be more affected than female dogs and large dog breeds were more affected than other breeds. The age wise analysis of faecal sample by KIT Ag test method revealed that the number of positive cases for CPV infection was 15.5%, 70.685% and 13.79% of animals belonging to age group 1-3, 4-12 and more than 12 months of age, respectively. whereas by PCR method revealed that the number of positive cases for CPV infection was 18%, 62% and 20% of animals belonging to age group 1-3, 4-12 and more than 12 months of age, respectively. The sex wise positive cases for CPV by KIT Ag test method was 67% and 33% for males and females, respectively whereas PCR method revealed that the positive cases were 68% in case of male and 32% among female. In the present study, it was found that the PCR method was more reliable, accurate and cost effective than KIT Ag method of diagnosis. The KIT Ag method of diagnosis is of more importance in field conditions for early detection of the disease before therapeutic approach.

Abstract: Fusarium wilt is one of the major yield limiting factors in tomato. In vitro and In vivo efficiency of two species of antagonists (Trichoderma viride and Trichoderma sp.) alone and in combination were evaluated against the pathogen (Fusarium sp.). In vitro results showed that Trichoderma viride and Trichoderma sp. significantly inhibited the mycelial growth of the pathogen. The mycelium inhibition of Fusarium was more effective by Trichoderma viride (52.31 %) compared to Trichoderma sp. (47.09 %). Both the species of Trichoderma also inhibited the growth of Fusarium in tomato planted pots as evident by the decrease in disease severity. The combination of both species of Trichoderma was more effective in controlling the disease along with increasing the tomato yield (34 % increase compared to the control) compared to their application as alone.

Abstract: A field experiment was carried out to investigate the effect of chemical weed management practices on nutrient uptake bytransplanted finger millet at harvest and its associated weedsin Southern dry Zone of Karnataka at College of Agriculture, V. C. Farm, Mandya. Different weed management practices involving herbicides, mechanical weeding, hand weeding were imposed in finger milletcrop. The results revealed that pre-emergence application of Bensulfuron methyl (0.6% G) + Pretilachlor (6.0 % G) @ 10 kg ha-1 recorded significantly lower total weed population and their dry weight and also as compared to unweeded check. Similar trend was also observed with nutrient uptake by weeds. However, pre-emergence application of significantly higher grain yield and straw yield as compared to unweeded check and it was followed by one intercultivation at 20 DAT followed by one hand weeding at 30 DAT and oxyfluorfen 23.5 EC at 80 g a.i./ha as pre-emergence application at 2 DAT (Table 2).

Abstract: A field experiment was conducted to study the effect of FYM and gypsum on onion (Allium cepa L.) production under sodic water irrigation. Treatments comprised of three levels of farm yard manure (FYM) (F0- no FYM, F1- 10 t/ha and F2- 20 t/ha FYM) and three levels of gypsum (G0- no gypsum, G1- 50% neutralization of RSC and G2- 100% neutralization of RSC) in addition to control (irrigation with sodic water and no FYM and no gypsum F0G0). Results of the study showed that the seedling mortality was maximum (77.50 %) in control (F0G0) treatment, while minimum number of seedlings mortality (18.17 %) was observed in (F2G2) treatment followed by (25.17 %) (F2G1) treatment. There was significant increase in growth and yield of onion with application of FYM and gypsum. Moreover, maximum bulb yield (180.83 q/ha) was recorded in (F2G2) followed by F2G1 (152.22 q/ha) where 100% sodicity of water was neutralized by the application of gypsum and 20 t/ha FYM.

Abstract: Gladiolus (Gladiolus hybridus L.) popularly known as “Queen of bulbous flowers”, member of family Iridaceae, is one of the most important bulbous ornamentals grown for its majestic spikes which contain attractive, elegant and delicate florets.The present investigation was carried out with 20 genotypes of gladiolus (Gladiolus hybridus L.) which were evaluated during 2013-14 in randomized block design with three replications. The performance of gladiolus data was highly significant for all the vegetative, flowering and corm traits. Cultivar Praha (81.28 cm) gave the maximum plant height followed by Regency (77.33 cm) whereas cultivars ‘Nathan White’ and ‘Arka Kesar’ were found earliest for spike initiation (56.01 day, 56.39 day respectively) and first floret showing color (68.77 day, 69.01 day respectively). The longest spike length and rachis length were found in Praha and American Beauty. Maximum number of florets per spike was found in Pacifica (14.87) and Yellow Golden (14.83). The maximum corm diameter (6.97) was found in Regency followed by Nathan White (6.56) whereas maximum numbers of cormels per plant were found in Tiger flame (33). Looking into performance of different cultivars, Praha, American Beauty, Pacifica, Tigar Flame and Priscilla can be recommended for cut flower production whereas Regency, Nathan White and Fidelio could be taken up for quality corm and cormel production and can also be further utilized in gladiolus improvement programme.

Abstract: A study was conducted for the assessment of combining ability for yield and agromorphological traits involving 10 parents and their 45 F1s (half diallel) during 2012-13 and 2013-14. The significant general combining ability (GCA) and specific combining ability (SCA) variances indicating the importance of both additive and non-additive gene effects for the traits studied. Present results also indicated that two parents (DBW 90 for days to emergence, spike length, biological yield and grain yield; HD 3095 for spike length, biological yield and grain yield) had favorable GCA effect for grain yield and agromorphological traits. Estimates of SCA effects revealed that the best crosses were HD 2967 x HD 2733, PBW 435 x HD 2733, HD 3095 x NW 5038, MP 3336 x NW 5038, MP 4010 x HD 3095, PBW 435 x MP 4010, HD 2967 x RAJ 4246, HD 3095 x HD 2733 and RAJ 4246 x NW 5038 which showed highest significant SCA effects for respective yield traits. Therefore these crosses should be given more emphasis in the development of desirable wheat genotypes for above respective traits in future wheat breeding programs.
