Mulches have been widely applied in crop production in order to minimize water requirements, preserve soil moisture, and curb weed growth for higher yield and water use efficiency. This research aimed to assess the impact of organic mulches on peanut productivity in the coastal areas of Thanh Hoa province.

Weed identification helps ensure crop yield and realize precision agriculture. Although the deep learning-based methods have achieved high performance, their needed large-scale annotated data is difficult to obtain, and the massive parameters lead to difficulties in model deployment in embedded applications. To develop efficient crop weeds classification system, we propose a dissimilarity-based method to select few but representative samples and consider data diversity.

Field experiments were conducted in 2009–2010 and 2010–2011 seasons to evaluate the effect of four post-emergence clodinafop-propargyl formulations (Topic 15% WP, Akopic 24% EC, Current 24% EC and Herstop 15% WP) and hand weeding for controlling annual grassy weeds in wheat fields.

This study was taken to know the weed control efficiency of herbicides in chickpea intercropping with lentil. The weed competition was highest during 30 DAS and the maximum weed density was found in 60 and 90 DAS. Weed species were recorded such as broadleaf weeds like Coronopus didymus, Chenopodium album, Melilotus officinalis, Phalaris minor, etc. The main focus of this experiment was to study dry matter accumulation by weeds at different days after sowing (30, 60, 90, and 120).

Different types and colours of plastic mulch have characteristic optical properties that change the levels of light radiation reaching the soil, causing increases or decreases in the soil temperature (Kasirajan and Ngouajio, 2012). Efficiency of plastic mulches varied according to the plastic colour i.e. white, black, blue, brown, green, red and yellow (Mahmood et al., 2002; Grundy and Bond, 2007; Dvořák et al., 2012).

Therefore, it is necessary, to find out the alternative methods for reducing the weed load during early growth period of soybean to get economical yields. Thus, herbicidal weed control remains only the choice under such situation to minimize the weed menace economically. Therefore, keeping the above facts in view, the present experiment has been carried outto find out effective weed control method.

Weeding is one of the major control operations in the vegetable crops. The traditional method of weed control is to remove the weed manually by a Khurpi or Spade. This is a very time consuming process. Due to shortage of agricultural labour in peak season, farmers cannot compete weeding in time. Mechanical weeding keeps the soil surface loose, which results in better aeration and moisture conservation. In our country the average land is about 0.

To the maximum extent feasible, it largely rely upon crop rotations, crop residues, animal manures, legumes, green manures, off farm organic wastes, mechanical cultivation, mineral bearing rocks and biological pest and disease control measures to maintain soil productivity and tilth to supply plant nutritions and to control insects, weeds and other pests (USDA Report, 1980).

An alarming fall in groundwater table in Northwest India demands a major shift from traditional method of rice cultivation to direct seeding of rice. Dry-seeded rice has emerged as a viable option to save water, labour, energy and time. Proper tillage and irrigation practices are needed to improve water productivity in dry-seeded rice through reduction in emergence of weeds and reduce ground water depletion and pesticide use. A field experiment was conducted at the research farm of the Department of Soil Science, Punjab Agricultural University...

The major yield advantages are related to proper crop establishment, efficient utilization of the natural resources and better weeds suppression due to proper plant population and together with other agronomic cultural practices. But in Jharkhand situation, information on optimum seed rate of suitable hybrid rice for aerobic is very meager.

Ginger (Zingiber officinale Roscoe) is grown in tropical and subtropical regions of the world for its spice and medicinal values. The emergence and early growth of ginger is inherently slow and weed growth can impact on yield. It has slow initial growth rate and shallow root system. As a result, it is invaded by a variety of weeds. A field experiment was carried out during 2015-16 and 2016-17 in randomized block design with three replications under AICRP on Weed Management at College of Horticulture and Forestry, CAU, Pasighat, Arunachal Pradesh, India with nine treatments.

Weeding is an important but equally labour intensive agricultural operation. Delay and negligence in weeding operation affect the crop yield and in many cases cause complete crop failure. Mechanical weed control not only uproots the weeds between the crop rows but also keeps the soil surface loose, ensuring better soil aeration and water intake capacity.

The integration of herbicides with some cultural operations and use of pre-emergence, post-emergence herbicides in combination with mechanical methods can prove to be more successful. This way integrated weed management is gaining importance in management of weeds for preventing losses and higher input-use efficiency (Ishya et al., 2007).
