Uniformity trials are needed to determine suitable shape and size of the plot for knowing the nature and extent of fertility variation in land, so that if some treatment has given good result, one should be confirmed that it is true and is not due to some other unknown reason. In these trials, a particular variety of crop is sown on the entire experimental field and throughout the growing season it is managed uniformly. The C.V. per cent per unit size decreased with the increase in plot size by increasing the length, the width or both. The greatest reduction in coefficient of variability was...

Sesam(Sesamum indicum L.) ist eine der ältesten Ölpflanzen der Welt und wird in Asien schon seit dem Altertum angebaut, wobei der Anbau in Indien am längsten zurückliegt. Die Bewirtschaftung von Ernterückständen ist eines der aufkommenden Probleme im Agrarsektor. Die Umwandlung organischer Abfälle in Biokohle ist eine praktikable Möglichkeit, die natürliche Kohlenstoffbindung im Boden zu erhöhen, landwirtschaftliche Abfälle zu reduzieren und die Bodenqualität zu verbessern. Biokohle kann die physikalischen, chemischen und biologischen Eigenschaften des Bodens wirksam verbessern...
