Potential for utilizing blended drainage water for irrigating west side, San Joaquin Valley pistachios

Ferguson L., Sanden B., Grattan S., Reyes H.C., Wilson C., Cross E.

Our results through 1999 demonstrate that six sequential seasons of irrigation with 8 dS per m water produced no significant effect on marketable yield of trees grown on the four major commercial California pistachio rootstocks. Two sequential seasons of irrigation water with 12 dS per m significantly decreased yield as follows. In 1997, trees grown on UCB-1 rootstocks had a 19 per cent decrease in marketable yield and trees on Atlantica rootstocks a 14 per cent, trees on PGI and PGII rootstocks had no decrease in yield. In 1998, trees grown on UCB-1 rootstocks had a 49 per cent decrease, trees on Atlantica rootstocks a 19 per cent, trees on PGII an 18 per cent, and trees on PGI a 14 per cent decrease in marketable yield. In 1999, yields dropped sharply as a result of alternate bearing, making yield comparisons useless.
