This paper discusses the potential benefits from shade management in agroforestry systems for taro cropping. Trial work to evaluate weed growth, taro production, and cultivar responses to shade levels are reviewed. It is concluded that weed growth can be reduced in tree-shaded plots without reducing corm production. Higher crop biomass is obtained when taro is grown under fifty percent shade co...

This paper presents a system for autonomously delivering a quantum of fluid to individual plants in a vegetable crop field, using a fine spray nozzle attached to a manipulator arm on a mobile robot. This can reduce input cost and environmental impact while increasing productivity for applications such as micro-nutrient provision, thinning and weeding. The Ladybird platform is introduced and a p...

The prime objective in this paper is to explore the possibility of combining the seemingly orthogonal processes of watermarking and encryption along the spirit of the chameleon cipher. By integrating perceptual models indirectly through a ’weeding’ process and collusion resistant coding methodologies in the design of the decryption keys, we have shown that it is possible to embed a robust yet r...

The experiment was conducted at agronomy farm of Sher-e-Bangla Agricultural University, Dhaka from November 2017 to April 2018 investigate the influence weeding regimes on performance white maize varieties. comprised two varieties viz. YANGNUO-3000 and PSC-121, designated as V1 V2 respectively combined with four weed control treatments T0 = No weeding, T1 One hand 60 DAS (days after sowing), T2...

Weeds are a problem in most communities and regulations exist regarding their control. However re-growth means that areas may have to be weeded several times year. The objective of this study was reduce or eliminate weed by destroying the root system. It demonstrated application high voltage effective for destruction selective possible.

in order to evaluate the competitive ability of legume cover crops on interference of weeds in corn, an experiment was carried out in sari agricultural sciences and natural resources university during 2011 growing season. this research was carried out based on complete block design with three replications. treatments consisted of three cover crops including: soybean (glycine max l.), fenugreek ...

Conventional methods of weed control are weather dependent, costly and labour intensive. Indiscriminate use of chemicals for controlling weeds may pose environmental problems. Sorghum allelopathy is a new technique, which has been tested for controlling weeds of wheat (Triticum aestivum L.) as a substitute for chemical herbicides to reduce environmental pollution. Mature sorghum herbage contain...
