e1“In 1976 and 1977, we conducted experiments at the University of California Agricultural Experiment Station at Riverside to evaluate drought effects on cowpeas during the vegetative, flowering, and pod-filling growth stages”
e7“There were several significant interactions between irrigation treatments and years on seed yields and concentrations of N, P, K, Ca, Mg, Zn, Mn, and Fe in the seeds”
