“…However, the cost of chemicals, land limitations which could not permit long rotations and the increasing pressure from environmentalists on the need for reduction in the use of chemicals in the environment led researchers to develop alternative approaches to deal with the root-knot nematode problem (Gildenhuys and Daulton, 1952;Selvaraj et al, 2014). Like in any crop production system, the use of integrated pest management including incorporating host resistance is encouraged (Thakur et al, 2012;Gnanavel and Natarajan, 2014). The search for tobacco germplasm resistant to Meloidogyne species showed that it was possible to develop root-knot nematode resistant tobacco through plant breeding efforts.…”

Virginia tobacco (Nicotiana tabacum L.) is currently the most popular field cash crop grown in Zimbabwe. The farming of Virginia tobacco in Zimbabwe started during the late 19 th Century with introduced varieties which succumbed to most of the locally occurring pests and diseases. One major pest of tobacco that threatens the success of growing the crop has been the root-knot nematode [Meloidogyne javanica (Treub) Chitwood]. The pest attacks the root system of the crop from as early as the seedbed stage to such an extent that yield losses of above 90% can be realised if the nematode is not controlled. In Zimbabwe, the threat posed by the pest in the success of the tobacco farming industry was realised as early as the 1950s and one of the approaches used to contain it was breeding for resistance into the local tobacco germplasm among other methods such as chemical control and cultural practices like crop rotation. This paper is a review of the process that was followed in incorporating root-knot nematode resistance in flue-cured tobacco germplasm in Zimbabwe. It shows the sources/origin of the root-knot nematode (M. javanica) resistance currently present in the Zimbabwean Virginia tobacco (N. tabacum) germplasm and the methods used in transferring the resistance to elite germplasm currently used in modern breeding programmes. The current study also suggests the way forward for the future breeding research for root-knot nematode (M. javanica) resistance in continuity of the past 50 years of breeding effort for resistance to the pest.

“…The optimum timing for stale seed bed preparation was 20 to 30 days before planting which provided adequate weed control and resulted in optimal yield (Lonsbary et al, 2003). Through stale seedbed method, weed population could be eliminated by pre-plant shallow tillage or by post emergence herbicide spray (Gnanavel and Kathiresan, 2014).…”

“…The idea that is submitted by the researcher is that the post-mechanical control should sort by the weeds so that those containing fruit and seed may be burned, meaning there will be no longer be any weed growth potential. This technique is less harmful and is cheap [26]. Then, the weeds that have no fruit or seed can be used as feed for the livestock.…”

The growth of weeds among agricultural crops is a pest that can decrease agricultural production by 47-87%. The aims of this research is to compare organic and an organic fertilizer and compare mechanical and chemical weed and pest control. This research employed a mixed-method, observation, in-depth interviews, and life cycle assessment. The greenhouse gas emissions were released are organic fertilizer 1,87 x 10-3 kg CO2 eq/ha and an organic fertilizer 15 x 101 kg CO2 eq/ha. Thereafter greenhouse gas emissions were released from mechanical control 1,87 x 10-3 kg CO2 eq/ha and chemical control 4,4 x 101 kg CO2 eq/ha. The totally of greenhouse gas emissions was released from dryland paddy farming in management phase is 19,4 x 101 kg CO2 eq/ha. Organic fertilizer more friendly than an organic fertilizer and mechanical control more friendly than chemical control. Mechanical control by farmers must be modified for the increase of effectiveness. The post-mechanical control should be those containing fruit and seed must be burned, meaning there will be not a longer any weed growth potential. Therefore, this mechanism will be able to realize potential production and sustainable dryland paddy farming.
