Pigeon pea [Cajanus cajan (L.) Millspaugh] is among the top ten legumes grown globally, along with common beans, pea, chickpea, broad beans and lentils. More than any other legume adapted to different agroclimatic zones, pigeon pea uniquely combines optimal nutritional profiles, high tolerance to environmental stresses, high biomass productivity and most nutrient and moisture contributions to the soil. It is a tropical grain legume grown mainly in India. Pigeon pea is nodulated by a wide range of rhizobial strains including Bradyrhizobium (cowpea group) and fast-growing rhizobia. Rhizobium-legume symbiosis is agriculturally and ecologically important for many purposes including the production of food, fodder, enrichment of the soil in nitrogen, thereby the application of nitrogenous fertilizers is reduced. Synergistic effects of plant growth promoting rhizobacteria (PGPR) and Rhizobium on nodulation and nitrogen fixation by pigeon pea (Cajanus Cajan) are well documented. These traits allow its cultivation in a range of environments and cropping systems.

An integrated and insightful look at successful drug synthesis in today¿s drug discovery market. The pharmaceutical industry is unquestionably vibrant today, with drug synthesis making a vital contribution. Whether in the early developmental stages of identifying and optimizing a lead, or the latter stages of process development and cost-effective scale-up, the ability to design elegant and economical synthetic routes is often a major factor in the eventual viability and commercial success of a drug. Contemporary Drug Synthesis examines how leading researchers and manufacturers have integrated chemistry, biology, pharmacokinetics, and a host of other disciplines in the creation and development of leading drug.

A plantação de cana-de-açúcar com plantação em filas emparelhadas em canteiros largos e sulcos, plantação em filas abertas em meia crista, e métodos de plantação mais largos melhoraram o crescimento, rendimento, atributos de rendimento e absorção de nutrientes de N, P, e K em relação à plantação convencional.A maior eficiência do uso de azoto agronómico (NUE), a percentagem de recuperação de azoto, e a eficiência do uso fisiológico de azoto também foram registadas no método de plantação em filas emparelhadas em canteiros largos e sulcos.Os parâmetros de qualidade da cana , nomeadamenteBrix Percent, Pol Percent, Purity Percent, e CCS Percent, não foram significativamente afectados por diferentes métodos de plantação e níveis de nitrogénio. Osresultados obtidos com a plantação em grandes linhas emparelhadas de canteiros e sulcos provaram ser um método mais promissor que deu mais rendimento líquido e benefício: relação custo. A maior produtividade e retorno líquido foram obtidos a 150 kg N ha-1.

La plantation de la canne à sucre avec laméthodede plantation en rangs jumelés sur lit large et sillon, la plantation par irrigation à sillon ouvert sur demi-billon et les méthodes de plantation plus larges ont amélioré la croissance, le rendement, les attributs du rendement et l'absorption des éléments nutritifs de N, P et K par rapport à la plantation conventionnelle.Lesparamètres de qualité de la canne, à savoirle pourcentage de Brix, le pourcentage de Pol, le pourcentage de pureté et le pourcentage de CCS, n'ont pas été affectés de manière significative par les différentes méthodes de plantation et les niveaux d'azote. Lesrésultats obtenus avec la méthode de plantation en rangs jumelés sur lit large et sillon se sont avérés être la méthode la plus prometteuse qui a donné un meilleur rendement net et un meilleur rapport bénéfice/coût. La productivité et le rendement net les plus élevés ont été obtenus à 150 kg N ha-1.

La siembra de caña de azúcar en cama ancha y surcoemparejado, la siembra en medio surco abierto y los métodos de siembra más amplios mejoraron el crecimiento, el rendimiento y los atributos de rendimiento y la absorción de nutrientes de N, P y K en comparación con la siembra convencional.La mayor eficiencia agronómica de uso de nitrógeno (NUE), el porcentaje de recuperación de nitrógeno y la eficiencia fisiológica de uso de nitrógeno también se registraron en el método de siembra en cama ancha y surco emparejado.Losparámetros de calidad de la caña , es decir,el porcentaje de Brix, el porcentaje de Pol, el porcentaje de pureza y el porcentaje de CCS, no se vieron afectados de forma significativa por los diferentes métodos de plantación y niveles de nitrógeno. Losresultados obtenidos con la plantación en cama ancha y en hileras emparejadas demostraron ser el método más prometedor, ya que proporcionó un mayor rendimiento neto y una mayor relación beneficio/coste. La mayor productividad y rendimiento neto se obtuvieron con 150 kg N ha-1.

L'impianto della canna da zucchero con la semina a file larghe e solchi accoppiati, con l'irrigazione a solchi aperti a mezza costa e con i metodi di impianto più ampi ha migliorato la crescita, la resa e gli attributi della resa e l'assorbimento dei nutrienti N, P e K rispetto all'impianto convenzionale.I parametri qualitativi della canna , qualipercentuale di Brix, percentuale di Pol, percentuale di purezza e percentuale di CCS, non sono stati influenzati in modo significativo dai diversi metodi di impianto e dai diversi livelli di azoto. Irisultati ottenuti con l'impianto a file affiancate a letto largo e a solchi si sono rivelati il metodo più promettente, in grado di fornire un rendimento netto e un rapporto benefici/costi più elevati. La produttività e il rendimento netto più elevati sono stati ottenuti con 150 kg di N ha-1 .

Die Anpflanzung von Zuckerrohr mit einem breiten Beet und einer Furche in zwei Reihen, die Anpflanzung mit halboffener Furchenbewässerung und die breiteren Anpflanzungsmethoden verbesserten Wachstum, Ertrag und Ertragsattribute sowie die Nährstoffaufnahme von N, P und K gegenüber der konventionellen Anpflanzung.Die höhere agronomische Stickstoffnutzungseffizienz (NUE), die prozentuale Stickstoffrückgewinnung und die physiologische Stickstoffnutzungseffizienz wurden ebenfalls bei der Anpflanzungsmethode mit einem breiten Beet und einer Furche in zwei Reihen festgestellt.DieQualitätsparameter des Zuckerrohrs, d.h.Brix-Prozent, Pol-Prozent, Reinheits-Prozent und CCS-Prozent, wurden durch die verschiedenen Anbaumethoden und Stickstoffgehalte nicht signifikant beeinflusst. DieErgebnisse, die mit der Anpflanzung von breiten Beeten und Furchen in gepaarten Reihen erzielt wurden, erwiesen sich als vielversprechendste Methode, die einen höheren Nettoertrag und ein besseres Kosten-Nutzen-Verhältnis lieferte. Die höchste Produktivität und der höchste Nettoertrag wurden bei 150 kg N ha-1 erzielt.

The sugarcane planting with wide bed and furrow paired row planting, half ridge open furrow irrigation planting, and wider planting methods improved growth, yield, and yield attributes and nutrients uptake of N, P, and K over conventional planting. The higher agronomic nitrogen use efficiency (NUE), percent nitrogen recovery, and physiological nitrogen use efficiency were also recorded in the wide bed and furrow paired row planting method. The cane quality parameters viz. Brix Percent, Pol Percent, Purity Percent, and CCS Percent were not significantly affected by different planting methods and levels of nitrogen. Results obtained with wide bed and furrow paired row planting proved to be a most promising method which gave more net return and benefit: cost ratio. The highest productivity and net return were obtained at 150 kg N ha-1.
