The present study was conducted to identify the impact of temperature indices on different phenophases and yield of cowpea varieties growing in Jhansi region of Uttar Pradesh, India. The cowpea (Vigna unguiculata L.) is a warm season legume crop grown in arid and semi-arid regions of India. Traditionally, it is very important as a staple food and source of fodder for the African continent, India and other semi-arid regions. A field experiment was conducted during rainyseasons (July to October) of 2010 and 2011 to determine the thermal indices for fodder cowpea varieties at Central Research Farm, ICAR-IGFRI, Jhansi. All the data were subjected to ANOVA using PROC GLM procedure in SAS (v 9.3). In ANOVA, varieties, date of sowing and year effect is considered as fixed factors and replication as random factor. Crop sown on 12th July took higher accumulated growing degree days (GDD) during 50% flowering (1111°C days) and maturity (2074°C days) as compared to crop sown during 4th August. Green fodder yield of Kohinoor recorded highest heat use efficiency (HUE) (32.4 kg ha-1°C day-1) over BL-2 and EC-4216 at the time of 50% flowering while it is at par with BL-1. From the results, it is found that early sownfodder cowpea recorded maximum duration, heat unit and heat use efficiency at maturity. The Variety Kohinoor recorded the highest grain yield, lowest calendar days and highest HUE as compared to all other varieties.

Hater resource managers in semi-arid regions are faced with some unique problems. The wide variations in precipitation and stream flows in semi-arid regions increase man's dependence on the ground water resource for an ample and reliable supply of water. Proper management of the ground water resource is absolutely essential to the economic well being of semi-arid regions. Historians have discovered the remains of vanished advanced civilizations based on irrigated agriculture which were ignorant of the importance of proper ground water resource management. In the United States a great deal of effort is presently being expended in the study and control of toxic discharges to the ground water resource. What many public policy makers fail to understand is that the potential loss to society resulting from the mineralization of the ground water resource is potentially much greater than the loss caused by toxic wastes discharges, particularly in developing countries. Appropriations for ground water resource management studies in developed countries such as the United States are presently much less than those for toxic wastes management and should be increased. It is the reponsibility of the water resource professional to emphasize to public policy makers the importance of ground water resource management. Applications of ground water resource management models in the semi-arid Central Valley of California are presented. The results demonstrate the need for proper ground water resource management practices in semi-arid regions and the use of ground water management models as a valuable tool for the water resource manager.
