The present investigation entitled, “Studies on performance of rejuvenated plants and fresh plants of guava cv. Hisar Safeda” was carried out at experimental orchard, Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2012-16. There were two treatments i.e. heading back and fresh plantation. Heading back of unproductive guava plants at the level of 0.5 m, 1.0 m and 1.5 m from point of emergence of main limbs was done during the month of January, 2012. New plants were planted in the month of February, 2012. Among different heading back treatments, plants headed back at 0.5 m level produced maximum fruit yield (30.70 kg/plant) whereas the yield from fresh plantation was 38 kg/plant at the age of four years. Maximum fruit size, fruit weight, TSS, ascorbic acid was recorded in new plantation, however, acidity was recorded minimum. Although in the first bearing after rejuvenation and fresh plantation the yield is higher in the rejuvenated plants but increase in yield was faster in fresh plantation in the ensuing seasons. It was also observed that the plant declining could not be stopped by rejuvenation in old plants. Hence, new plantation was observed better option.
