Effect of different weed management practices on soil properties and soil and leaf nutrient content of plum (Prunus salicina L) cv Red Beaut

The present investigations were carried out in the experimental orchard of Horticultural Research and Training Station and Krishi Vigyan Kendra, Solan, Himachal Pradesh during the year 2016-17. The experiment was laid out in randomized block design with ten treatments comprising weedicides, mulching and hand weeding which were replicated thrice. Maximum soil organic carbon (1.73%), available soil nutrients content (N 283.29 kg/ha, P 27.12 kg/ ha and K 255.56 kg/ha) and leaf nutrients content (N 2.62%, P 0.19% and K 1.95%) and yield (17.49 kg/plant) were recorded in treatment having grass mulching which was statistically at par with the treatment of pendamil @ 5.3 ml/ l of water followed by gramoxone @ 5 ml/l of water among different weed management practices which was also found to be cost effective and most economical treatment.
