1. Evaluation and Management of Palatable Halophytes for enhancing fodder Resources in Arid Gujarat

2. Activities assigned and accomplishment made 2018-19 Activity target for 2018-19 Achievement i ). Evaluation of Halophytes for growth and yield. Field experiments conducted. ii).Response of halophytes to nutrient-K application. Field experiment conducted. iii). Optimization of plant density for higher fodder yield. Field experiment conducted but failed due to very less rainfall

3. Palatable halophytes Aeluropus lagopoides Cress cretica Suaeda nudiflora Sporobolus marginatus

4. Green and dry fodder yield (t/ha)-2018-19 Dry and green fodder yield differed significantly. Maximum and significantly higher dry fodder yield of 3.57 t/ha. recorded by S. marginatus , followed by S. nudiflora (3.03 t/ha). The lowest dry fodder yield of 1.32 t/ha by C. cretica .

6. Response of Grass-halophytes to K application is significant and linear (r=-0.901) Non-grass halophytes is quadratic (R2=0.879)
