Abstract
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
