A field experiment was conducted at the Division of Agronomy, Indian Agricultural Research Institute, New Delhi during 1983-84 and 1984-85 to study the effect of lentil residues on the yield and response of succeeding rice to nitrogen. Lentil residues benefitted the succeeding rice and gave longer and heavier panicles, more grains per panicle, higher 1000-grain weight and higher grain and straw yield of rice as compared to fallow. Rice responded well to applied nitrogen both in the absence and presence of lentil residues. The effect of lentil root residues and root residues plus incorporation of lentil straw was equivalent to 11 and 33 kg N ha⁻¹ when 60 kg N ha⁻¹ was applied to rice; the corresponding values being 54 and 60 kg N ha⁻¹ when 120 kg N ha⁻¹ was applied to rice.  相似文献

Physiological and biochemical effects of glyceryl guaiacolate-thiopentone sodium anaesthesia in buffalo calves   总被引：1，自引：0，他引：1  

K B Agrawal  B Prasad  V K Sobti 《Research in veterinary science》1983,35(1):53-57

Glyceryl guaiacolate was used with thiopentone sodium for general anaesthesia in 10 clinically healthy male buffalo calves. When the animals were in the stage of surgical anaesthesia, there was marked hypotension and tachycardia along with a decrease in central venous pressure, tidal volume, partial pressure of oxygen in arterial blood and venous plasma potassium. Hyperglycaemia was another consistent feature. The changes in the acid base status were mild and inconsistent.  相似文献

Esterase, malate, and lactate dehydrogenases activity in murine neuroblastoma     

R Prasad  N Prasad  K N Prasad 《Science (New York, N.Y.)》1973,181(98):450-451

Mouse neuroblastoma tumors have only the fifth isozyme band (A(4)) of lactate dehydrogenase, whereas this band is missing in the brain which contained four other bands of lactate dehydrogenase. The alpha-esterase isozyme patterns of tumors, kidney, and brain are similar except that there is an additional slowest-moving form of esterase in all tumor tissues. The malate dehydrogenase pattern is not altered in any of the tissues.  相似文献   

Effect of a Winter Cereal or Legume Crop on the Yield and Nutrient Uptake by Summer Maize/Cowpea Fodder     

M. George  R. Prasad 《Journal of Agronomy and Crop Science》1989,163(3):212-214

A field experiment conducted at the Indian Agricultural Research Institute, New Delhi brought out that summer maize green fodder yield was 31.8 t/ha to 34.1 t/ha, while that of cowpea fodder was only 15.5 to 16 t/ ha. Maize fodder and crude protein yield and NPK uptake was more after a winter legume (lentil) than after a winter cereal (wheat).  相似文献

Note: Proline — An inducer of resistance against pearl millet downy mildew disease caused by<Emphasis Type="Italic">Sclerospora graminicola</Emphasis>     

Sathyanarayana?Niranjan?Raj  Nandini?Prasad?Shetty  Hunthrike?Shekar?ShettyEmail author 《Phytoparasitica》2004,32(5):523-527

In an attempt to find a suitable alternative to the otherwise perilous chemical control strategy of disease management, the amino acid proline was evaluated for its efficiency to elicit resistance in pearl millet (Pennisetum glaucum (L.) R. Br.) against downy mildew disease caused bySclerospora graminicola (Sacc.) Schroet both under greenhouse and field conditions. Proline treatment to seeds at 50 mM concentration for 3 h, significantly enhanced the seed germination and seedling vigor of pearl millet in comparison with the control. The same concentration and duration of seed treatment protected the pearl millet plants from downy mildew by offering 58% protection under greenhouse and 67% protection under field conditions. Studies revealed that 3 days were required for proline-treated plants to develop resistance, which was systemic and was sustained throughout the life of the plants. Apart from disease protection, proline was also found effective in enhancing vegetative and reproductive growth of the plants, as evidenced by the increase in height, fresh weight, leaf area, tillering capacity, 1000-seed weight and grain yield in comparison with the control plants. http://www.phytoparasitica.org posting Oct. 3, 2004.  相似文献   

Isolation and characterization of neutral lipids of desilked eri silkworm pupae grown on castor and tapioca leaves     

Shanker KS  Shireesha K  Kanjilal S  Kumar SV  Srinivas C  Rao JV  Prasad RB 《Journal of agricultural and food chemistry》2006,54(9):3305-3309

The neutral lipid of desilked eri silkworm pupae (Samia cynthia ricini) grown on two different host plants, castor (Ricinus communis Linn.) and tapioca (Manihot utilizsima Phol.) leaves, was extracted with hexane. The oil content in pupae was estimated to be in the range of 18-20% (dry basis). The pupal oil was found to be enriched with alpha-linolenic acid (ALA) with palmitic acid as the second major fatty acid. The level of ALA in the oil of silkworm pupae was found to be significantly higher (P < 0.001) when grown on tapioca (58.3%) as compared to those grown on castor (42.9%). Other chemical parameters such as percent free fatty acid, peroxide value, phosphorus content, percent unsaponifiable matter, and composition of sterols were also determined in both of the oils and compared. Reversed-phase high-performance liquid chromatography analysis of triacylglycerol molecular species showed that the pupal oil is rich in molecular species with equivalent carbon numbers (ECN) C36, C40, C42, C44, and C48. There was a significantly higher level (P < 0.001) of trilinolenin (C36) in the oil of tapioca-based silkworm as compared to castor-based silkworm pupae. Regiospecific analysis of the oil showed a higher level of ALA at the sn-2 position of silkworm pupae grown on tapioca (60.2%) as compared to those grown on castor (47.3%) oil. Thus, the presence of a large amount of ALA and their predominance at the sn-2 position make the eri pupal oil highly nutritious, provided that the oxidative stability is ensured.  相似文献   

Morphological, anatomical and molecular investigation into witches’ broom disease of mamejvo (Enicostemma axillare)     

K. Abirami  Anjali Sharma  Jatindra Nath Samanta  V. S. Rana  Kunal Mandal 《Phytoparasitica》2012,40(5):445-450

Mamejvo (Enicostemma axillare Raynal) is a perennial herb with diversified health benefits. It was found to be affected by a witches?? broom disease under the field conditions at Anand, Gujarat, India. Affected plants were 53.33% reduced in height due to shortened internodes, leading to typical witches?? broom symptoms. Flower size was reduced significantly in the affected plants compared with the healthy ones and their petal color gradually turned green (virescence). Affected plants produced 2.5 times more dry herbage than the normal plants but with less active ingredient (swertiamarin). Symptomatic plants died early while root suckers from such plants failed to establish after transplanting. DAPI stained transverse sections of affected shoot tips showed the presence of discrete greenish fluorescence in the phloem cells under UV light. Amplification of 1.2?kb phytoplasma specific rDNA fragment from diseased tissue confirmed the presence of the pathogen. Further characterization of the pathogen through virtual rDNA?CRFLP pattern and rDNA sequence based phylogeny suggested that the pathogen, Enicostemma witches?? broom phytoplasma, belonged to 16SrII?CC group of ??Ca Phytoplasma aurantifolia??.  相似文献
