ABSTRACT
The present study entitled, “Effect of different weed management practices on
plum (Prunus salicina) cv. Red Beaut” was carried out in the experimental farm located at
Jadari of HRTS and KVK Kandaghat, Dr YS Parmar University of Horticulture and Forestry,
Nauni, Solan, Himachal Pradesh, during the year 2016-17. The experiment was laid out in
Randomized Block Design (RBD) with ten treatments and three replications. The treatments
comprise of T1: Pendamil @ 5.3 ml/L of water, T2: Gramoxone @ 4 ml/L of water, T3:
Gramoxone @ 5 ml/L, T4: Gramoxone @ 6 ml/L of water, T5: Pendamil @ 5.3 ml/L of water
followed by Gramoxone @ 4 ml/L of water, T6: Pendamil @ 5.3 ml/L of water followed by
Gramoxone @ 5 ml/L of water, T7: Pendamil @ 5.3 ml/L of water followed by Gramoxone
@ 6 ml/L of water, T8: Grass mulching, T9: Hand weeding at 30 days interval and T10:
Control (Unweeded).Among different weed management practices grass mulching was found
to be most effective for enhancing different plant growth parameters like increment in tree
height, tree volume, trunk girth, annual shoot extension growth, leaf area and leaf chlorophyll
content. Fruit characters like fruit length, diameter, weight and volume were also found to be
better under grass mulching treatment. Grass mulching treatment also had higher soil nutrient
contents. From economical point of view treatment T6 (Pendamil @ 5.3 ml/L of water
followed by Gramoxone @ 5 ml/L of water) gave thebest results. It was furtherobserved that
treatment T6 (Pendamil @ 5.3 ml/L of water followed by Gramoxone @ 5 ml/L of water) had
many of the results at par with treatment T7 (Pendamil @ 5.3 ml/L of water followed by
Gramoxone @ 6 ml/L of water) andT8 (Grass mulching
