A field experiment entitled, “Integrated weed management in Kharif maize (Zea mays L.)” was conducted during Kharif, 2020 at Post Graduate Research Farm, RCSM College of Agriculture, Kolhapur. The experiment was laid out in Randomized Block Design (RBD) having three replications and twelve treatments. The soil of the experimental plot was medium black clay (vertisol) with 90 cm depth, low in available N (250 kg ha-1), high in available P2O5 (30.60 kg ha-1) and medium in available K2O (290.67 kg ha- 1). The status of organic carbon content (0.34%) was low. The electrical conductivity and pH values were 4.2 dSm-1 and 7.10, respectively.Weed free check and tank mixure application of Tembotrinone 42 SC @ 120gm a.i.ha-1 + Atrazine 50 WP @ 500 gm a.i.ha-1 + surfactant @ 2ml/l of water EPoE At 20-25 DAS + fb hand weeding at 40 DAS were on par with each other and recorded significantly the higher growth and yield contributing characters viz., plant height (cm), number of functional leaves plant-1, leaf area plant-1(dm2), dry matter plant-1(g), length of cob (cm), diameter of cob(cm), number of grains, weight of grains cob-1and test weight resulting into significant increase in grain and straw yields of maize as compared to remaining weed management treatments. Tank mixure application of Tembotrinone 42 SC @ 120gm a.i.ha-1 + Atrazine 50 WP @ 500 gm a.i.ha-1 + surfactant @ 2ml/l of water EPoE At 20-25 DAS + fb hand weeding at 40 DAS recorded minimum dry weight of weed, highest weed control efficiency (86.94 %) and lowest weed index (1.79%).Significantly lowest values for growth, yield and yield attributes as well as weed control efficiency was observed in weedy check treatment.

The Impact

A field experiment conducted to evaluate the impact of integrated weed management on economics of Kharif maize (Zea mays L.) during Kharif, 2020 at Post Graduate Research Farm, RCSM College of Agriculture, Kolhapur. The field experiment was laid out in Randomized Block Design (RBD) having eight treatments replicated thrice.Weed free check and tank mixure application of Tembotrinone 42 SC @ 120gm a.i.ha-1 + Atrazine 50 WP @ 500 gm a.i.ha-1 + surfactant @ 2ml/l of water EPoE At 20-25 DAS + fb hand weeding at 40 DAS were on par with each other and recorded significantly increase in grain and straw yields of maize as compared to remaining weed management treatments. Significantly lowest values for yield and yield attributes was observed in weedy check treatment.Maximum gross monetary returns and net monetary returns were observed in weed free check treatment was Rs. 183225.5 ha-1 and Rs. 126320.7 ha-1, respectively. Tank mixure application of Tembotrinone 42 SC @ 120gm a.i.ha-1 + Atrazine 50 WP @ 500 gm a.i.ha-1 + surfactant @ 2ml/l of water EPoE At 20-25 DAS recorded maximum B: C ratio (3.34).

The Vegetation Analysis of Weeds in Corn (Zea mays L.) Plantation and Its Conjunction with Weed Control in Lambung Bukit, Padang, West Sumatra         Research about the vegetation analysis of weeds in corn (Zea mays L.) plantation and its conjunction with weed control in Kelurahan Lambung Bukit, Padang, West Sumatra had been conducted from March to Juny 2011 by using systematic squares method of 10 total plots with size 1x1 m2. It was found consist of 10 families, 15 genera,16 species and 1892 individuals weeds. Spermacoce alata (Rubiaceae) showed the highest value of Summed Dominance Ratio (23,17%) and the lowest rate of SDR Hedyotis sp., Cyperus cephalotes and Amaranthus sp. (0,65%). The diversity index of the weeds was H'= 1,2005 (moderate). Integrated weed management is a concept that prioritizes natural control by creating environmental conditions that not favorable for the development of weeds and improve the competitiveness of crops against weeds.Keywords: Weeds, corn, composition, structure, control ABSTRAK         Penelitian mengenai analisis vegetasi gulma pada pertanaman jagung dan hubungannya dengan pengendalian gulma di Kelurahan Lambung Bukit, Padang, Sumatera Barat telah dilaksanakan dari bulan Maret sampai Juni 2011. Penelitian dilakukan dengan menggunakan Metode Kuadrat sebanyak 10 plot dengan ukuran 1x1 m2. Pada penelitian ini didapatkan 10 famili, 15 genus, 16 jenis, dan 1892 individu gulma. Gulma yang memiliki nilai SDR tertinggi yaitu gulma jenis Spermacoce alata famili (Rubiaceae) dengan nilai Summed Dominance Ratio (SDR)  23,17 % dan nilai SDR terendah Hedyotis sp., Cyperus cephalotes dan Amaranthus sp. (0,65%). Nilai indeks dari keanekaragaman jenis gulma berada pada nilai H’ = 1,2005 (sedang). Pengelolaan gulma terpadu merupakan konsep yang mengutamakan pengendalian secara alami dengan menciptakan keadaan lingkungan yang tidak menguntungkan bagi perkembangan gulma dan meningkatkan daya saing tanaman terhadap gulmaKata Kunci: Gulma, Jagung, Komposisi, Struktur, Pengendalian
