Abstract : An experiment was conducted from June 1990 to April 1991 to study the effects of fertilizers and irrigation on the yield and quality of chemically induced (by KNO3) Carabao mango grown in the pomology orchard of Central Luzon State University. The treatments consisted of complete fertilizer (14-14-14 N-P-K) at 0, 2 and 4 kg/tree and irrigation at fortnightly intervals from full bloom or no irrigation. Flowering percentage was significantly higher on the fertilized trees than on the unfertilized ones but fertilized trees took longer for buds to emerge. Fertilizer application and irrigation produced longer and wider panicles, greater fruit set per panicle, maximum fruit retention per panicle at harvest and higher yields per tree. The highest yield of 88.58 kg/tree was obtained with 2 kg complete fertilizer per tree and irrigation at fortnightly intervals. However, fertilizer application and irrigation decreased fruit weight and fruit size, lengthened the ripening period and increased percentage fruit weight loss. Fertilizer application increased pH and TSS but decreased TA and DM in ripe fruits. Irrigation reduced pH, TSS and DM, but increased TA in ripe fruits.
