“…Thus, enhanced availability of nutrients, moisture, light and space which might have accelerated the photosynthetic rate, thereby increasing the supply of carbohydrates, resulted in increase in growth characters. These findings are in agreement with those of Singh et al, (2012) [12] , Ahmed and Susheela (2012) [1] , Hatti et al (2015) [6] , Rana et al (2017) [11] and Sundari et al (2019) [15] . The data presented in Table 1 revealed that the number of cobs per plant were significantly influenced by different weed management practices.…”

“…There are some production problems and weed problem is one of them owing to wider spacing and non-tillering habit. Uncontrolled weed growth throughout the crop growing period caused 43% reduction in grain yield (Rao et al, 2009) [12] . Herbicides alone or in combination with other weed management techniques reduce weed-crop competition and the risk of weeds growing unchecked in the initial growing period (Angiras et al, 2010;Fakoor et al, 2010) [2,5] .…”

A field experiment was conducted on medium black calcareous soil at Junagadh (Gujarat) during Rabi season of 2019-20 to study the bioefficacy of herbicides and their mixtures for weed management in Rabi maize (Zea mays L.). The experiment was laid out in randomized block design with three replications. The treatments comprised of: Atrazine 500 g/ha as PE fb 2,4-D (SS) 500 g/ha as PoE at 30 DAS, Atrazine 500 g/ha as PE fb halosulfuron-methyl 60 g/ha PoE at 30 DAS, Atrazine 500 g/ha as PE fb tembotrione 100 g/ha as PoE at 30 DAS, Atrazine 500 g/ha as PE fb topramezone 25 g/ha as PoE at 30 DAS, Atrazine 500 g/ha as PE fb tank-mix halosulfuron 30 g/ha + 2,4-D (SS) 250 g/ha at 30 DAS, Atrazine 500 g/ha as PE fb tank-mix halosulfuron 30 g/ha + tembotrione 50 g/ha at 30 DAS, Atrazine 500 g/ha as PE fb tank-mix halosulfuron 30 g/ha + topramezone 12.5 g/ha at 30 DAS, HW at 15 and 30 DAS, Weed free check and Unweeded check. The results of the experiment indicated that application of atrazine 500 g/ha as PE fb tembotrione 100 g/ha as PoE at 30 DAS, atrazine 500 g/ha as PE fb topramezone 25 g/ha as PoE at 30 DAS and HW at 15 and 30 DAS improved growth and yield attributes, suppressed weed growth, and ultimately recorded higher grain and dry fodder yields of maize along with higher net returns.

“…into overall improvement in crop growth as reflected by plant height and dry weight consequently resulted into better development of reproductive structure and translocation of photosynthates into the sink. The results corroborated with the findings ofKaur and Singh (2006) andRao et al (2009). The maximum ear head length (28.5 cm) was observed under the weed free treatment which was statistically at par with two hand hoeing, two hand wheel hoeing, atrazine 0.500 kg ha -1 PE, 2,4-D 0.300 and 0.500 kg ha -1 .…”

Current status and prospects of herbicide‐resistant grain sorghum (Sorghum bicolor)

Grain sorghum is a versatile crop, which can thrive under limited water and other inputs. However, crop loss from weed infestation continues to be a major constraint in grain sorghum production. Particularly, post‐emergence grass weed control is a great challenge in grain sorghum due to the lack of herbicide options. Unlike in other major crops, such as maize or soybean, herbicide‐resistant sorghum technology that can facilitate weed control throughout crop growing season is not available to growers yet. The development of herbicide‐resistant sorghum can have potential to improve weed management, including post‐emergence grass weed control. One of the major concerns in the development of such technology in sorghum is escape of resistance traits into weedy relatives of sorghum (e.g. shattercane and johnsongrass). This review focuses on sources of herbicide resistance in sorghum, the status of the development of herbicide‐resistant sorghum technologies, overview of breeding methods, and limitations in the development of such sorghum technology as well as economic benefits for sorghum growers. © 2021 Society of Chemical Industry.
