“…Two hand weeding during the crucial phase of crop weed competition of rice crop, i.e. up to 45 DAT can result in the minimum weed density and the maximum weed control efficacy [4]. Also, the manual weeding is more flexible than mechanical weeding due to the fact that cultivating implements, cannot be used when removing weeds within rows and hills.…”

An field experiment was conducted during Kharif season of 2021at the Organic Farming Research Centre, Chatha, SKUAST- J to evaluate the effect of different weed management practices on nutrient uptake and yield in organic basmati rice production. The experiment was conducted in Randomized Block Design with 11 treatments which were replicated thrice. The highest nitrogen (29.66 kg/ha), phosphorus (16.22 kg/ha) and potassium (32.66 kg/ha) uptake by weeds were recorded in weedy check. Amongst organic weed management treatments, application of vinegar @ 10 % at 5 DBT + hand weeding at 30 DAT which was though statistically at par with recommended practice of two hand weeding at 20 and 40 DAT recorded significantly lowest nitrogen (2.31 kg/ha), phosphorus (1.21 kg/ha) and potassium (2.44 kg/ha) uptake by weeds followed by the application of vinegar @ 5 % at 5 DBT + hand weeding at 30 DAT and application of rice bran @ 2.5 t/ha (extract at 1:3 wt./vol. basis) at 5 DBT + hand weeding at 30 DAT than weedy check and other organic weed management treatments in comparison. However, maximum grain and straw yield was recorded with the application of vinegar @ 10% at 5 DBT fb one hand weeding at 30 DAT to the tune of 31.17 q/ha and 54.27 q/ha, respectively. Thus, it may be concluded that the application of vinegar @ 10 % at 5 DBT fb one hand weeding at 30 DAT may be recommended as economical viable option in organic basmati rice crop.

The effect of planting density and weed management on weed control, yield and quality of a non-Basmati type short-grained scented rice (cv. Radhunipagal) was studied at 'C' Block Farm of Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal. The field experiment was conducted in a split-plot design comprising 2 spacings (15 cm × 15 cm and 20 cm × 15 cm) in main plots and 6 weed control practices [weedy check, 2 hand weeding (HW), Butachlor as pre-emergence (PE) + HW, Butachlor (PE) + 2,4-D Na-salt as post-emergence (PoE), HW + 2,4-D Na-salt (PoE), mechanical weeding + HW) in sub-plots during rainy (kharif) season of 2013 and 2014. Mean number of total weeds in 1 m2 field was 94.3 and 118.8 at 28 and 56 days after transplanting (DAT); and weed control efficiency varied among 5 weed management practices over weedy check as: 49.0-67.3% at 28 DAT and 56.5-72.8% at 56 DAT. Close planting (15 cm × 15 cm) resulted in 9.1% greater grain yield (2.27 vs. 2.08 t/ha), higher net income (Rs. 23,700 vs. 20,900/ha) and B:C ratio (1.79 vs. 1.73) over wider spacing (20 cm × 15 cm). Manual weeding twice at 21 and 42 DAT recorded better weed control efficiency (67.3 and 72.8% at 28 and 56 DAT), grain yield (2.51 t/ha), milling recovery (65.9%) and net return (Rs. 25,900/ha). But chemical weed control [Butachlor (PE) + 2,4-D Na-salt (PoE)] was adjudged as less expensive option (Rs. 27,300/ha) for Radhunipagal rice with moderate grain yield (2.16 t/ha ), higher protein content (7.45%) and B: C ratio (1.90).
