Effect of leaf cutting on physiological traits and yield of two rice cultivars

Field experiments were conducted during two summer seasons 2003 and 2004 to study the effect of leaf cutting on physiological traits and yield of two rice cultivars hybrid (H5) (IR 70368 A /G 178) and inbred rice. The leaf cutting was followed from flag leaf as follows: 1.)  L; Control = without leaf cutting, 2.) L1; flag leaf cut, 3.) L2; second leaf cut, 4.)  L3; third leaf cut, 5.) L4; both flag leaf and...

Watermelon production on stored rainwater in Sahelian sandy soils

Watermelon [Citrullus lanatus (Thumb) Matsun and Nakai ] is an important cash crop in West Africa where it is cultivated under rainfed conditions. The objective of this work was to identify best cultural practices for production of watermelons in the Sahel on stored rainwater in acid sandy soils. The experiments were carried out at the ICRISAT Sadore research center in Niger during two consecutive dry...
