Field experiments evaluated the effects of integrated nutrient management on symbiotic parameters, growth, nutrient accumulation, productivity and profitability of lentil (Lens culinaris Medikus). Application of recommended dose of nutrients (RDN, 12.5 kg N ha^?1 + 40 kg P₂O₅ ha^?1) + 25 kg ZnSO₄ ha^?1 + seed inoculation with biofertilizers [Rhizobium + phosphate solubilizing bacteria (PSB) + plant growth promoting rhizobacteria (PGPR)] + 1.0 g ammonium molybdate kg^?1 seed recorded the highest number & dry weight of nodules, leghaemoglobin content, root & shoot dry weight, plant height, number of pods plant^?1 and 100-seed weight. The next best treatment was RDN + seed inoculation with biofertilizers + 1.0 g ammonium molybdate kg^?1 seed. On the basis of mean of three-year data, the treatment of RDN + 25 kg ZnSO₄ ha^?1 + seed inoculation with biofertilizers + 1.0 g ammonium molybdate kg^?1 seed proved the best in realizing the highest grain yield (34.0%), gross returns (34.0%) and net returns (54.8% higher over control). Nitrogen, phosphorus and potassium in the grains and straw were significantly improved where RDN was applied in combination with seed inoculation, basal application of ZnSO₄ and seed treatment with 1 g ammonium molybdate than their single applications.  相似文献   

Response evaluation criteria for peripheral nodal lymphoma in dogs (v1.0)–a veterinary cooperative oncology group (VCOG) consensus document

Standardized assessment of response to therapy for lymphoma in dogs is lacking, making critical comparisons of treatment protocols difficult. This Veterinary Cooperative Oncology Group (VCOG) consensus document, based on the recommendations of a subcommittee of ACVIM board-certified veterinary oncologists, was unanimously adopted at the 29th Annual Conference of the Veterinary Cancer Society (VCS) by the VCOG membership. It has integrated guidance from the response assessment criteria established for lymphoma in human patients using standards available in routine veterinary oncology practices that are simple, repeatable and consistently applicable. These guidelines are intended only for use in dogs, where peripheral lymphadenopathy represents the principal component of their disease and as such do not critically assess extranodal disease (e.g., primary cutaneous, central nervous system, gastrointestinal). It is hoped these guidelines will be widely adopted and serve to facilitate the comparison of current and future treatment protocols used in the therapy of dogs.  相似文献   

Solarization for the control of Pueraria montana (kudzu)     

CH NEWTON  LR NELSON  SJ DEWALT  EA MIKHAILOVA  CJ POST  MA SCHLAUTMAN  SK COX  WC BRIDGES  KC HALL 《Weed Research》2008,48(5):394-397

The effects of translucent polyethylene sheeting as a thermal covering to eradicate Pueraria montana (kudzu) were investigated at Clemson, South Carolina on a clay loam. In 2005, the highest reduction of live root crowns was observed where P. montana was covered for the entire growing season (May–October) with a reduction of 42% of live root crowns compared with the control plots. Where P. montana was covered for alternate weeks throughout the growing season live root crowns were reduced by 35%. Covering P. montana for one week and then uncovering for four weeks repeatedly through the season killed 24% of root crowns. In 2006, the second year of treatment to the same plots, the three solarization treatments had similar efficacy of about 97%. The use of polyethylene sheeting appears not to be cost‐effective for general control of large P. montana infestations, but may be useful for small patches.  相似文献   

Yield enhancement and phosphorus economy in lentil (Lens culinaris Medikus) with integrated use of phosphorus,Rhizobium and plant growth promoting rhizobacteria     

Narinder Singh  Navneet Aggarwal  Veena Khanna 《Journal of plant nutrition》2018,41(6):737-748

The study evaluated the effects of phosphorus (0, 20, 30, and 40 kg P₂O₅ ha^?1) and biofertilizers [Rhizobium (Rhizobium leguminosarum bv viciae), plant growth promoting rhizobacteria (PGPR) (Pseudomonas fluorescens), Rhizobium + PGPR, and uninoculated control] in lentil. Application of 40 kg P₂O₅ ha^?1 resulted in the highest number of nodules, nodule dry weight, leghemoglobin content in nodules, chlorophyll content, yield attributes, and grain yield. Coinoculated treatment performed better than uninoculated control, and individual inoculations of Rhizobium and PGPR in terms of all above mentioned parameters. Application of 20 kg P₂O₅ ha^?1 + Rhizobium inoculation gave statistically similar and 20 kg P₂O₅ ha^?1 + Rhizobium + PGPR inoculation gave significantly higher grain yield than that by 40 kg P₂O₅ ha^?1 alone. The use of Rhizobium alone and Rhizobium + PGPR consortium can save not only 20 kg P₂O₅ ha^?1 but also increase the grain yield of lentil.  相似文献   

Relationship of temperament with oestrous behaviour,resumption of ovarian cyclicity and milk yield in post‐partum Murrah buffaloes          下载免费PDF全文

This study was designed to investigate the relationship of temperament with oestrus, resumption of ovarian cyclicity and milk yield in post‐partum buffaloes. For this study, 102 post‐partum Murrah buffaloes were observed for temperament in open paddock and during milking. Based on the temperament score (1–5 score), they were classified into docile, slightly restless, restless, aggressive and nervous. Oestrous behaviour was monitored twice daily in all the buffaloes along with milk yield (weekly), body weight (BW) and body condition score (BCS) at day 0, 30, 60 and 90 post‐partum. Based on the temperament score, the number of buffaloes classified as docile, slightly restless, restless and aggressive was 37 (36.27%), 28 (27.45%), 30 (29.41%) and 7 (6.86%), respectively, but none under nervous category. Number of buffaloes resuming cyclicity in various temperaments groups were as follows: docile (n = 35; 94.59%), slightly restless (n = 22; 78.57%), restless (n = 20; 66.67%) and aggressive (n = 7; 85.71%). Temperament was not correlated (p = .128; r=?.152) with oestrous behaviour. But, temperament was correlated (p < .0001; r = .384) with the resumption of cyclicity as docile and slightly restless buffaloes resumed cyclicity (p < .0016) earlier. Temperament of buffaloes was weakly correlated (p = .0017; r=?.306) with milk production with higher (p < .0358) total milk yield in docile (1022 ± 23.75 kg) and slightly restless buffaloes (948 ± 35.86 kg) as compared to other temperament groups. In summary, temperament of post‐partum buffaloes was related with resumption of ovarian cyclicity and milk yield, but not oestrous behaviour.  相似文献

Electronic, magnetic, and geometric structure of metallo-carbohedrenes     

Reddy BV  Khanna SN  Jena P 《Science (New York, N.Y.)》1992,258(5088):1640-1643

The energetics and the electronic, magnetic, and geometric structure of the metallocarbohedrene Ti(8)C(12) have been calculated self-consistently in the density functional formulation. The structure of Ti(8)C(12) is a distorted dodecahedron with a binding energy of 6.1 electron volts per atom. The unusual stability is derived from covalent-like bonding between carbon atoms and between titanium and carbon atoms with no appreciable interaction between titanium atoms. The density of states at the Fermi energy is high and is derived from a strong hybridization between titanium 3d and carbon sp electrons. Titanium sites carry a small magnetic moment of 0.35 Bohr magneton per atom and the cluster is only weakly magnetic.  相似文献

本试验自2002年开始至2004年止，从种植密度和施肥水平两方面对大豆脂肪、蛋白质含量的影响进行了分析。结果表明：种植密度对大豆籽粒的脂肪、蛋白质含量具有显著的影响，相关性分析结果显示，种植密度与大豆籽粒的脂肪含量存在着负相关性，与籽粒中的蛋白质含量之间为正相关。中国品种的脂肪含量受种植密度的影响大于美国品种，而中国品种的蛋白质含量受种植密度的影响小于美国品种。蛋脂总含量受种植密度的影响较小，并且不存在品种间的差异性。磷酸二铵的施用量与大豆籽粒脂肪含量和蛋白质含量之间没有显著的相关性，但是中美品种的品质对磷酸二铵施用量的反应不同。磷酸二铵的施用量与中国品种的脂肪含量、蛋白质含量和蛋脂总含量呈正相关，而与美国品种的脂肪、蛋白质含量和蛋脂总含量呈负相关，但相关程度均不显著。  相似文献   

Factors affecting the production of filled seeds in sunflower     

K. R. Khanna 《Euphytica》1972,21(2):384-387

Summary The capitulum and stem diameter have been found to be negatively correlated with the percentage of the filled seed. The correlation is significant. The partial correlation between the above is also negative but the values are not significant which shows that it is the joint interaction of stem and capitulum diameter which markedly influences seed set. It has been concluded that increased stem thickness adversely affects seed set because of greater increase in leaf area which in turn restricts nutrient supply to the developing seeds. Both stem and capitulum diameter are important from yield point of view as they lead to increased seed producing area. It is essential for a good variety to have large capitula with well filled seeds. It has been pointed out that in a breeding program it should be possible to get desired combinations of above characters without much difficulty.  相似文献   

Prospects of breeding opium poppies (Papaver somniferum L.) as a high-linoleic-acid crop     

S. P. Singh    K. R. Khanna    S. Shukla    B. S. Dixit  R. Banerji 《Plant Breeding》1995,114(1):89-91

Fatty-acid composition was studied in a half diallel in opium poppies using six parents, F₁ and F₂. Poppy is an oleic-linoleic-acid type of crop with a low level of linolenic acid of up to 3% or only trace. Transgressive segregation was observed in F₂ having up to 81% linoleic acid making it suitable for development as a high-linoleic-acid crop. This is the first report of its kind in opium poppy.  相似文献
