The effect of different qualities of irrigation water viz. canal water (CW), alternate CW and saline water (CW-SW) and CW irrigation up to germination and subsequent irrigation with SW (CWg-SW) along with three N fertigation levels [100% (N100), 80% (N80) and 60% (N60) of recommended dose of N (RDN)] on dry matter (DM) partitioning of Bt cotton at successive stages of growth [60, 90, 120 days after sowing (DAS) and at harvesting stage] after 3 cycles of cotton –summer squash cropping system under surface drip irrigation system during kharif 2019 at PAU Regional Research Station, Bathinda was observed in a field experiment laid out in split design with four replications in paired row geometry (50-85-50 cm) with drip lateral placed in the middle of paired rows having in-line emitter spacing of 30 cm and discharge rate 2.4 L hr-1. The dry matter of leaves, stem and roots increased with increasing age of cotton plant, irrespective of irrigation water quality (IWQ) and N fertigation levels. The maximum vegetative growth of cotton occurred between 60 and 90 DAS. A significant decrease in DM accumulation in all parts of plant was observed under increasing salinity of irrigation water in CWg-SW treatment. The dry matter yield of all the plant parts increased with each additional N increment. However, the magnitude of increase narrowed down beyond N80 fertigation level. Among the partitioned plant parts, maximum DM accumulation occurred in leaves at 60 DAS, in the stem at 90 DAS, in burr/seed cotton along with lint at 120 DAS, irrespective of IWQ and N levels. To conclude, cyclic use of good quality CW and SW of EC up to 4.0 dS m-1 (CW-SW) are statistically at par with CW in terms of DM production of cotton on sandy loam soil in semiarid environment with surface drip.
