Abstract:

A study was carried out during the pre-kharif season of 2018 and 2019 at Pundibari, Cooch Behar, West Bengal, to evaluate the efficacy of pre and post-emergence herbicides in tossa jute (Corchorus olitorius L.) over manual weeding. The experiment was laid out in a randomized complete-block design with 9 treatments, replicated thrice. The study results revealed that post-emergence herbicide-treated plots reduced the weed density by 7496% and weed biomass by 7293% compared to non-treated plots. Manual weeding twice-treated plots reduced the weed density by 8292%. Pre-emergence herbicides failed

Abstract:

Now a days weeding necessitates the introduction of suitable power weeders for pulse cultivation. A study was conducted at TNAU fields with 3 models of commercially available power weeders (Model A, B and C). To suit the power weeder the crop geometry was modified with 60x10 cm and the performance of three power weeder models were compared with conventional method of hand weeding. The working width of the power weeders was 60 cm, 60 cm and 30 cm respectively for Model A, B and C. Manual weeding using hand hoe registred maximum weeding efficiency of 83.10 per cent (wet basis) and 82.5 per cent

Abstract:

Maize crop development is directly related to the rapid emergence and uniform growth of plants, which can significantly assist in the competitive ability for resources such as water, light and nutrients, and competition with invasive plants can limit the physiological stages of plants, preventing their development. Given the above, this work aimed to evaluate maize cultivation under different manual weeding periods .

Abstract:

Weed control is one of the major problems in crop and vegetable production in Nigeria. Most of the peasant farmers use manual weeders in their cultivation, a process that is costly, labour intensive and time consuming. The process does not also give the farmer adequate returns to enable him breakeven. It is, therefore, necessary to design a weeding equipment which minimize the human effort and provide efficient work output for the peasant farmer.

Abstract:

The purpose of the study was to study the effect of agrotechnical measures and herbicides aimed at reducing weed infestation and increasing the productivity of tomato fruits when grown in the Republic of Kalmykia. The most effective was the combined use of agrotechnical and chemical measures to combat weeds, which made it possible to reduce the infestation of tomato plantings of the Podarochny variety by 91.1-94.0%. An increase in the number of cultivations from 3 to 6 (against the background of herbicides) did not lead to a significant decrease in the weediness level. It was revealed that the

Abstract:

A key enabling factor for treating individualized weeds in the crops is the Automatic Weeding Control device (AWCd) as it is being capable of finding and distinguishing weeds in the field. The non-herbicide approaches used to manage weeds are a component of the personalized treatment of weed crops. In this study, mechanical weed control techniques are investigated as an alternative. In this study, three specifications—a cutting mechanism, a head-surface tilling (tines), and a foot-surface tilling (arrow hoe)—are taken into account.

Abstract:

This study explores the effectiveness of various herbicides in enhancing upland rice production in the Fogera Plain of Ethiopia, a region recognized for its agricultural potential yet challenged by significant weed infestations. Despite a notable increase in both cultivated area and total rice output, the productivity in Ethiopia remains below the global average, primarily due to the adverse effects of weeds. To address this issue, a trial was conducted using a randomized complete block design (RCBD) during the 2023 rainy season, evaluating the impacts of Keeper herbicide, Pallas 45 OD, and ma
