K.Productivity and production of the major crops has increased many folds since the independence. Simultaneously, the use of chemical fertilizers has also increased which have caused negative impact the on-soil‘s health. The extensive use of chemical fertilizers can be reduced by their precise application. Nitrogen is one of the most important among chemical fertilizers. Some researchers have found that nitrogen fertilizer can be applied on the basis of soil‘s electrical conductivity. Mostly, the soil‘s electrical conductivity is measured in laboratory which takes more time. If EC is managed to be measured within the field on real time basis then it can be employed at the time of sowing the crop. Therefore, a project on development of real time soil EC sensing system was taken. Four electrodes were used to measure electrical conductivity of soil. Out of four electrodes, outer two electrodes were used for current flow in the soil which is kept 6 cm deep and voltage (potential difference) between inner two electrodes were measured which was also at same depth. Two methods i.e. soil-salt and salt-water were used to vary the EC of soil as well as water. Two relationships i.e. EC vs V were developed for soil-salt and salt-water which were used for the calibration equations. The coefficients of determination (R2) were 0.849 for EC vs V (soil-salt method) and 0.793 for EC vs V (salt-water). The Pearson‘s coefficients of correlations were 0.921 and 0.891 for the same which were significant. A multiple regression equation (EC, V and MC) was also determined. The coefficient of determination was 0.793 for the same which was also significant. Using above equation program was written to measure EC in real time. The developed sensor was validated in actual field condition. To validate the developed sensor, sensing system was operating in the field and measure EC in real time. Simultaneously, soil samples were also collected to measure EC in lab. The measured data by sensor was validated lab data. The coefficient of determination was 0.651 Therefore, the developed sensing system is very simple, easy to use to measure EC in real time which will reduce the time and drudgery substantially.ArticleItem Open Access ThesisItem Open Access Effect of addition of aldehydes and sugars onheat stability of buffalo milk(NDRI, Karnal, 1979) Ghatak, Pijuskanti; Singh, AjitThesisItem Open Access Effect of carbonyl and aldehyde compounds on the heat stability of lactose free buffalo milk(NDRI, KARNAL, 1985) Sundararaju, C; Singh, AjitThesisItem Open Access Effect of heating and chilling on the compositional and structural properties of fat globule membrane from recombined milk.(NDRI, Karnal, 1990) Janbandhu, T.J.; Singh, AjitThesisItem Restricted Effect of Hyperthyroidism and hypothyboidism on growth egg production and haematology in Poultry(College of Veterianry medicine, Hissar, 1969) Bhardwaj, Sudesh; Singh, AjitArticleItem Open Access ThesisItem Open Access Effects of nutrition and growth on thyroid activity in buffalo calves(Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, 1972) Singh, Virk, Jatinder; Singh, AjitHerbal feed additives (9) were used either individually or in combination at 0, 0.4, 0.8 or 1.2 percent level to assess the effect on in vitro gas production and digestibility of nutrients using berseem and wheat straw as substrates. The effect of herbs irrespective of level or type of substrate used indicated that net gas production, true organic matter digestibility and availability of ME from the substrate were maximum (P<0.05) when it was supplemented with either bhringraj, kutki or jeera. The effect of level of herb used irrespective of type of herb or substrate used revealed that net gas production and available ME from the substrate was improved significantly in the groups supplemented with herbal feed additives as compared to unsupplemented group. However, supplementation beyond 0.4 per cent did not have any beneficial effect on utilization of nutrients. Further, berseem was more responsive to herbal additives than wheat straw. The 9 herbal feed additives divided into 3 groups viz. shatavari-jiwanti-bhringraj; mustakjeera-saunf or kutki-chitrak-soe were mixed either in 3:1:2 or 1:1:1; 3:1:2 or 1:1:1; 1:4:2 or 1:1:1, respectively. Each combination was tested at 4 levels. The effect of combination irrespective of level, proportion in which each herb was mixed and type of substrate used revealed that digestibility of nutrients as well as availability of ME were maximum (P<0.05) when shatavari-jiwanti-bhringraj were supplemented in 3:1:2 ratio. This combination at 0.4 per cent level was considered as best combination. Rumen fistulated male buffalo calves (6) were offered control diet of concentrate mixture and wheat straw without any herbal supplement. Rumen contents were collected after 30 day adaptation period. Thereafter, control diet was supplemented with either bhringraj, kutki or combination of bhringraj-kutki (1:1) for 30 days. The pH in the SRL of animals fed diet supplemented with herbs increased significantly as compared to animals in control group. The herbal supplementation did not have any significant effect on the different N fractions in the rumen. The metabolism trial conducted before the termination of 77 day growth trial on 20 buffalo calves revealed that the daily dry matter intake, digestibility of nutrients and N-retention were also improved to some extent in the animals fed diet supplemented with kutki. The herbal supplementation did not have any significant impact on the daily live weight gain in buffalo calves except that maximum daily gain was observed in animals fed bhringraj supplemented diet.ThesisItem Open Access Effects of Nutrition and growth on thyroid activity in Buffalo Calves(College of Veterianry Medicine, PAU-Ludhiana, 1972) Virk, Jatinder Singh; Singh, AjitThesisItem Open Access Effects of Thyroidectomy and Replacement therapy on grwoth, Organ Wetoht and histological changes in Dest Chickens(College of Veterianry medicine, PAU Hissar, 1968) Parsad, Omkar; Singh, AjitArticleItem Open Access Electrophoretic and gel filtration behavior of goat milk proteinsSingh, Ajit; Ganguli, N.
