Abstract:
A field experiment was conducted at Research Farm, Agronomy Section, RCSM College of Agriculture, Kolhapur, Maharashtra (India) during 2022-23 with an objective of studying effect of weed management practices on sugarcane. The experiment was laid out in randomized block design with seven treatments, each of which replicated three times. The statistically analyzed data on given objective reveled that all weed management treatments have shown significant impact on growth and yield attributes of sugarcane over weedy check. Among the herbicidal treatments, Post emergence application (PoE) of 2, 4-D amine salt 58% SL @ 1.4 kg a.i. ha^-1 + Metribuzin 70% WP @ 0.875 kg a.i. ha^-1 at 30 days after planting (DAP) recorded significantly lowest weed count, weed index and weed dry weight with maximum weed control efficiency over weedy check treatment. The growth of sugarcane in terms of tillers, plant height, dry weight with highest number of millable canes, number of internodes, and single cane weight, commercial cane sugar yield (CCS) and cane yield (t ha^-1) were recorded in treatment of 2, 4-D amine salt 58% SL @ 1.4 kg a.i. ha^-1 + Metribuzin 70% WP @ 0.875 kg a.i. ha^-1 at 30 days after planting (DAP). The quality parameter with respect to brix not affected by any weed management practices.
