Tank mix application of tembotrione and atrazine to reduce weed growth and increase productivity of maize

The present investigation entitled “Effect of Herbicide Combinations on Growth and Yield of Kharif Maize (Zea mays L.)” was carried out during kharif 2019 at College Farm, College of Agriculture, Badnapur, Dist.-Jalna. Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, Maharashtra (India). Randomized Block design was used for study comprised of ten treatments. Among treatments, weed free treatment attributed more number of leaves, maximum plant height, dry matter production and leaf area per plant followed by treatment of topramezone 33.6 % SC @ 25.2 g a.i.ha-1 + atrazine 50 % WP @ 250 g a.i. ha-1. Poor growth attributes were recorded in weedy check. Significantly maximum values of yield attributes were recorded in treatment of topramezone 33.6 % SC @ 25.2 g a.i.ha-1 + atrazine 50 % WP@ 250(g)a.i.ha-1 followed by treatment of tembotrione 42 % SC @ 105 g a.i. ha-1+ atrazine 50% WP @ 250 g a,i. ha-1. Minimum values of yield attributes were attributed in weedy check. Treatment of topramezone + atrazine @ 25.2 + 250 g a.i ha-1 as PoE (T6) found effective in limiting weed growth and recorded lower weed index, weed dry matter with higher weed control efficiency followed by tembotrione +atrazine @105 + 250 (g) a.i.ha-1as PoE (T7) at all growth stages of crop. The benefit cost ratio was highest (2.94) with application of topramezone + atrazine @25.2 + 250 g a.i ha-1 followed by tembotrione + atrazine @ 105 + 250 g a.i. ha-1 as PoE (2.81) whereas weedy check recorded significantly lower B:C ratio(1.50) over other treatments.

“…A similar trend was observed for stover yield and biological yield of maize with respect to weed management practices. Grain yield enhancement percentage over weedy check was Sharma et al (2018) and Kumar et al, (2017), Raghuwanshi et al, (2023).…”

“…This enzyme is responsible for the carotenoid formation, which disrupt chlorophyll synthesis as well as photosynthesis and ultimately resulting in mortality of weeds. By controlling weeds population, it helped to minimized the weed competition and increased the nutrient uptake by the maize (Sharma et al, 2018;Singh et al, 2012;Williams et al, 2011).…”

“…The lower dose of tembotrione + atrazine 1000 g/ha were found relatively less effective compared to tembotrione + atrazine 1500g/ha and tembotrione + atrazine 1250 g/ha but significantly better than tembotrione 286 ml/ ha, atrazine 2000 g/ha and weedy check. Such results recorded might be due to the fact that the herbicide tembotrione and atrazine ready mixture effectively controlled the weeds, minimized the weed competition and thereby increased the nutrient uptake by the plants and less dry matter accumulation in weeds (Sharma et al, 2018;Chhokar et al, 2020).…”

Background: Maize, being highly productive and versatile cereal crop, is influenced by various biotic and abiotic stresses. Among biotic stresses, weed infestation is one of the serious concerns in maize cultivation. Weeds can affect maize by competing for light, water and nutrients resulting in yield loss of up to 70% in severe cases. Methods: A field experiment was conducted during kharif season for two consecutive years of 2019 and 2020 in agriculture farm of Palli Siksha Bhavana (Institute of Agriculture), Visva-Bharati, Sriniketan, West Bengal, India. The experiment was laid out in randomized block design and replicated thrice. The experiment comprised of seven weed management treatments viz. T1 (tembotrione 9% + atrazine 45% WG @ 1000 g/ha), T2 (tembotrione 9% + atrazine 45% WG @ 1250 g/ha), T3 (tembotrione 9% + atrazine 45% WG @ 1500 g/ha), T4 (Tembotrione 34.4% SC @ 286 ml/ha), T5 (Atrazine 50% WP), T6 (Hand weeding), T7 (Weedy check). Result: Experimental results revealed that among different herbicide mixtures, tembotrione + atrazine 1500 g/ha was found to be effective in suppressing the weeds growth and found no residual effect on soil chemical and biological properties during both the years of the experiment.

“…Girase et al (2017) noted that the highest grain yield of pearl millet was obtained with pre-emergence application of atrazine 0.5 kg/ha + 1 HW at 35 DAS. Sharma et al (2018) reported that the combined application of tembotrione with atrazine was significantly superior to its sole application, which considerably reduced weed density, dry weight, weed index, higher weed control efficiency, and increased values of growth, and yield attributes and yield of the crop.…”

An experiment was conducted on rainfed pearl millet at ICAR- IARI, New Delhi, during the kharif season of 2019, in a split-plot design with three replications. Three tillage practices, viz. Conventional tillage (CT), Zero tillage and Zero tillage + Residue@ 3t/ha (ZT+R) were evaluated in the main plot and seven weed management treatments, viz. weedy check, hand weeding (HW) at 30 and 50 days after sowing (DAS), atrazine @ 0.75 kg/ha(PE) fb 2,4-D @0.75kg/ha (PoE), atrazine @ 0.75 kg/ha PE, atrazine @ 0.75 kg/ha PE fb tembotrione @ 0.05kg/ha PoE, atrazine @ 0.75kg/ha PE fb tembotrione @ 0.075kg/ha PoE, atrazine @0.75 kg/ha PE fb tembotrione @ 0.10 kg/ha PoE. ZT+R 3t/ha resulted in enhanced growth attributes, and higher NPK uptake which led to increased grain yield. Among weed control treatments, hand weeding (HW) twice at 30 and 50 DAS along with the integration of pre-emergence application of atrazine 0.75kg/ha fb 2,4-D 0.75kg/ha PoE and tembotrione, 0.075 kg/ha or 0.1 kg/ha PoE resulted in better growth attributes which significantly resulted in higher grain yield under rainfed conditions of semi-arid tropics.
