The trails were conducted on cash crops i.e. sugarcane and cotton. In cotton integrated weed control and in sugarcane Sustainable Sugarcane Initiative (SSI) technology was popularized among farmers. Horticultural crops covered under study were onion and pomegranate. In the same way in onion crop to reduce the cost of cultivation integrated weed management and in pomegranate to protect the fruits from sun scorching PP Non woven bag technology was demonstrated at farmer’s field.

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).

A field experiment on weed management in rice-garlic under organic production system was conducted during 2017-18 to 2019-20 at All India Coordinated Research Project on Integrated Farming System, Rewa (M.P.). The study reveals that maximum grain yield of rice and bulb yield of garlic was noted under incorporation of mustard oilcake @ 50 quintal per hectare with one hand weeding followed by two hand weeding at different stages under organic production system.

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.

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).

Presence of diverse weed flora during critical period of crop-weed competition, is one of the major obstacles in conservation agriculture that reduces which can reduce the crop yield appreciably significantly. During critical period of crop-weed competition, chemical method of weed control is by far the most preferred way to minimize the weed infestation of weeds, farmers are mostly relying on chemical methods of weed management.
