This study aimed to determine the effect of partial root drying (PRD) and regulated deficit irrigation (RDI) on growth performance of rock melon (Cucumis melo Linn cv. Glamour). A randomised complete block design experiment with four replications was conducted at Universiti Putra Malaysia in 2012. Different deficit irrigation levels had significant effects on dry matter production and yield of melon as compared to well-watered (WW) as controls. Maximum and significant yield of melon was from the WW and RDI plants. RDI a moderate water stress did not drastically reduce fresh fruit weight of melon i.e. a 28 drop in yield indicating better utilisation of the available water. However for PRD the yield drop 80. Maximum total soluble solids of 14.02 13.83 and 5.99 o Brix was from WW RDI and of PRD treated plant respectively. Total proline concentration in leaf at 76 days after transplanting clearly illustrates that the PRD plants is highly stressed by this deficit system with maximum reading of 21.44 g/g as compared to only 9.68 and 9.97 g/g from WW and RDI plants respectively. Results obtained suggest the possibility of applying moderate deficit irrigation at 50 watering capacity while maintaining the quality and yield of melon.

Abstract

This study aimed to determine the effect of partial root drying (PRD) and regulated deficit irrigation (RDI) on growth performance of rock melon (Cucumis melo Linn cv. Glamour). A randomised complete block design experiment with four replications was conducted at Universiti Putra Malaysia in 2012. Different deficit irrigation levels had significant effects on dry matter production and yield of melon as compared to well-watered (WW) as controls. Maximum and significant yield of melon was from the WW and RDI plants. RDI a moderate water stress did not drastically reduce fresh fruit weight of melon i.e. a 28 drop in yield indicating better utilisation of the available water. However for PRD the yield drop 80. Maximum total soluble solids of 14.02 13.83 and 5.99 o Brix was from WW RDI and of PRD treated plant respectively. Total proline concentration in leaf at 76 days after transplanting clearly illustrates that the PRD plants is highly stressed by this deficit system with maximum reading of 21.44 g/g as compared to only 9.68 and 9.97 g/g from WW and RDI plants respectively. Results obtained suggest the possibility of applying moderate deficit irrigation at 50 watering capacity while maintaining the quality and yield of melon.
