The $2.1 million invested for the sweet corn research breeding program resulted in the release of Hybrix5 in 1995 which is a new sweet corn variety with improved insect and disease resistance. Based on the ex-post evaluation of this research program, it was estimated that the net benefits of the...

Irrigation enterprises can be evaluated from a perspective of technical and environmental efficiency. This study determines the technical and environmental efficiency in irrigated cotton enterprises. This is achieved by investigating efficiency at cotton enterprise in the case study area of the...

Hybrid rice, one of the viable and proven technologies has been considered as a new frontier to increase rice production for meeting growing demand for staple food in Bangladesh. Using farm survey data this paper examines comparative profitability of hybrid and inbred rice cultivation and...
