Pimentel E.A.
Magsanaya upland rice and yellow corn variety yielded just as well at soil pH 4.0 and pH 5.6 while the other test crops yielded lesser at soil pH 4.0. Liming to pH 5.6 and fertilization significantly increased the yield of IPB hybrid corn, Phil 6019 sugarcane, peanut and mungo-pag-asa variety. In a fertilized alimodian clay loam soil with pH 4.0, different rates of liming gave significant results to the different field crops. The highest net return among the test crops was shown by Magsanaya upland rice. All the other test crops showed considerable reduction in net profit.
