| Abstract | Effects of water deficit at various growth stages on yield and quality of pineapple cv. Phulae was studied at Chiang Rai Horticultural Research Center, Chiang Rai Province, between the Year 2016 to 2018. The experimental design was RCB with 4 replications of6 treatments. Treatments consisted of the period of water deficit at: early growth stage, lategrowth stage, flower forcing stage, fruit development stage, fruit enlargement stage andpre-harvest stage. The experiment was carried out in two consecutive seasons. Ratoons ofthe first season were repetitively used in the second season. It was found that no-wateringin early growth stage affected D-leaf length, leaf length was shorter in both seasons. Nosignificant differences nitrogen, phosphorus, potassium, calcium and boron content inD- leaf were found in both seasons and each water deficit period. Fruit weight reducessignificantly if water deficit occurred at pre-harvest stage, the average weight were 1.23and 0.52 kg/fruit in seasons 1 and 2 respectively, but the fruits had better quality, both intaste and TSS content than those from other treatments. In addition, the lack of water atvegetative stage made fruits quality more unsatisfactory than at fruits development stage,while the lack of water at flower forcing stage had not affected the pineapple fruit quality. |
