Effect of Conditioning Zinc Sulfate Heptahydrate (ZnSHH) with Zinc Oxide (ZnO) and Neem Oil on Growth,Productivity, Zinc Biofortification of Grain and Zinc Uptake by Basmati Rice

Commercial grade zinc (Zn) sulfate hepta hydrate (ZnSHH) is the most widely used source of Zn in India and several other countries for amelioration of Zn deficiency in crops. However, it releases water of hydration at temperature above 30°C and forms lumps on storage, which make it difficult to handle it and apply in fields. Therefore, conditioning of ZnSHH with ZnO and neem oil reduces the release of water of hydration and prevents lumps formation and can be well stored. Field experiments were conducted at the research farm of the Indian Agricultural Research Institute, New Delhi, India during rice growing seasons (July-November) of 2009 and 2010 to study the effect of conditioning ZnSHH with ZnO and neem oil on growth, productivity and Zn fortification of rice (Oryza sativa) grain and uptake by Basmati rice ‘Pusa 1121’. The experiment was conducted in a randomized block design with 3 replications comprised of 9 treatments of Zn fertilization. The present study shows that when conditioned with 2% ZnO and 4% neem oil ZnSHH improved yield attributes, grain and straw yields, Zn uptake and partial factor productivity (PFP), agronomic efficiency (AE), recovery efficiency (RE), and physiological efficiency (PE) of Zn in Basmati rice ‘Pusa 1121’. In general, ZnO was inferior to ZnSHH. Application of ZnSHH conditioned with 2% ZnO and 4% neem oil can be a better source of Zn for transplanted puddled Basmati rice on Zn deficient soils.  相似文献

Growth and Biochmical Studies of Mrigal Fish (Cirrhinus mrigala) Fed Graded Levels of Oil     

Aderolu Ademola Zaid  Sahu Narrotam Prasad  Fawole Femi John  Nwachi Oster Francis 《东北农业大学学报(英文版)》2017,24(3)

A 45-day experiment was carried out to evaluate the growth performance,digestive enzymes activity and biochemical response of Cirrhinus mrigala fed graded levels of oil.Three isonitrogenous purified diets(6%,8%and 10%of oil)were formulated.A total of 108 juveniles of Cirrhinus mrigala(5.95±0.25)g were equally distributed in triplicate groups in nine plastic tanks of 100 L capacity and fed under natural light cycle.Growth performance of the fish significantly reflected the effect of inclusion levels of oil tested but the diet with 8%lipid had the best significant growth performance[%weight gain,Feed Conversion Ratio(FCR)and Specific Growth Rate(SGR)],across different experimental groups.Levels of secretion of digestive enzymes in the fish fed different experimental diets resulted in significant values of(p0.05)amylase and lipase,while Aspartate transaminase(AST),Alanine transaminase(ALT),Lactate dehydrogenase(LDH)and Malate dehydrogenase(MDH)values in the muscle and liver decreased significantly(p0.05)as the levels of oil in the diet increased.However,serum biochemical parameters did not record any significant difference(p0.05)with the exception of the total lipid across diets.The study confirmed the inclusion effect of graded levels of oil in juvenile Mrigal diet,but the inclusion should not be more than 8%to avert growth depression.  相似文献

Influence of moisture regime on inhibition of nitrification by DCD     

Rajendra Prasad 《Archives of Agronomy and Soil Science》2013,59(4-5):495-500

A laboratory study at the Indian Agricultural Research Institute, New Delhi showed that DCD was an efficient nitrification inhibitor under field capacity moisture (???30 kPa) but not so under submerged soil conditions. Nitrification inhibition by DCD was 79.6% after 1 week of incubation and decreased to 59.3% after 3 weeks of incubation under field capacity moisture, while it was only 19.3% after 1 week of incubation and 10.6% and 18.4% after 2 and 3 weeks of incubation under submergence, respectively. DCD can play an important role in reducing N losses from agricultural fields.  相似文献   

Temporal variation in mineral nitrogen in soil as influenced by incorporation of legume or cereal residues under submergence or well drained conditions     

R. Prasad  D. K. Singh  R. K. Singh 《Archives of Agronomy and Soil Science》2013,59(1-2):133-139

A laboratory study was conducted at the Indian Agricultural Research Institute, New Delhi on a sandy clay loam soil of pH 7.9 and organic C content of 0.34% to study the effect of incorporating Sesbania or Vigna legume residues or wheat straw at 15 and 30t ha^?1 on temporal variation in ammoniacal and nitrate‐N in soil under submergence and well drained conditions. Under submergence most mineral N was present as ammoniacal‐N, while under well drained conditions it was present as Nitrate‐N. The content of ammoniacal N in soil was the highest after 30 days of incubation and declined thereafter under submergence. On the other hand under well drained conditions the mineral‐N (mostly nitrate) content in soil at 30 DAI was very little and showed increases only later, reaching the highest level at 90 DAI. Application of wheat straw specially at 301 ha^?1 level resulted in immobilization of native soil‐N. These results show that rice which is grown under submergence can be transplanted soon after incorporation of legume residues, but for wheat or other crops which are grown under well drained condition a time interval of 30 days or more needs to be provided before sowing the crop.  相似文献   

Non-suture intestinal anastomosis by invagination     

B Prasad  S A Ahmed  G A Bhatt 《The Journal of small animal practice》1972,13(11):641-647

Intestinal anastomoses were performed on seventeen mongrel dogs by non-suture invagination technique and by the conventional method. A comparative evaluation revealed the non-suture technique to be easier and less time-consuming. Also the tissue reaction was minimal. Encouraging results suggest further investigation prior to clinical trial of this relatively new technique. Résumé. Des anastomoses intestinales sur dix-sept chiens métis par l'invagination technique pas de suture et la méthode de convention. Une évaluation comparative a révélé que la technique pas de suture était plus facile et moins de temps était perdu. Aussi la réaction du tissu était minimum. Les résultats encourageants proposent un surcro***ît d'investigation antérieurement a l'expérience clinique de cette technique relativement plus nouvelle. Zusammenfassung. Die Darmanastomosen von siebzehn Mischhunden durch die Intussuscep-tiontecknik keiner Naht und die verabredete Methode. Eine vergleichende Abschatzung zeigte, daß die Tecknik keiner Naht leichter ist, und wenigere Zeitverschwendung hat. Auch war die Reaktion des Gewebes minderst. Die ermutigenden Ergebnisse suggerieren eine Forderung der Erforschung vor klinischem Versuch dieser Tecknik, die verhältnismäßig neuere ist.  相似文献   

TREATMENT OF DIAPHRAGMATIC HERNIA IN BUFFALOES   总被引：2，自引：0，他引：2  

J. Singh    B. Prasad    R. Kumar    R. N. Kohli  S. S. Rathor 《Australian veterinary journal》1977,53(10):473-475

The surgical treatment of diaphragmatic hernia attempted on 19 lactating buffaloes is described. Thirteen cases recovered uneventfully, 1 recovered after developing brisket oedema and 5 died, 3 during surgery and 2 postoperatively. The desired depth of anaesthesia was achieved by the administration of 6% chloral hydrate followed by 5% thiopentone sodium. A postxiphoid approach and the use of a continuous lock stitch suture were preferred to repair the vent in the diaphragm. Pre- and post-operative use of hydrocortisones and fluids and sufficient tissue oxygenation by controlled positive pressure respiration are believed to be keys to the success of the treatment adopted.  相似文献
