Tobacco (Nicotiana tabacum L.) has grown to become a major cash crop and foreign currency earner in Zimbabwe. The crop’s popularity in the country is dependent on the climatic and soil conditions that promote the production of flavour style cures which are well sought after by the majority of tobacco merchants and cigarette manufacturers across the world. The success story of tobacco farming in Zimbabwe is mainly attributed to the presence of an organised research system in the form of the Tobacco Research Board (TRB) that includes a dedicated division in the research unit specialising in variety development and promotion. Improvement in yield and quality of the cured leaf has are the main objectives of flue –cured tobacco breeders. Since the beginning of research in flue cured tobacco production in Zimbabwe, a lot of effort has been dedicated to improving these and other associated traits. This review paper traces the process of breeding for improvement in yield and quality in flue-cured tobacco in Zimbabwe. It shows the methods employed and identifies some of the potential sources of genes for use in improvement in flue-cured tobacco yield and quality in present and future breeding work.

Since its introduction to Zimbabwean farmers in the early 20th Century, flue –cured tobacco has grown to become one of the most profitable field crops to cultivate in the country. However, pests and diseases have been reported as some of the major contributors to yield and quality loss in the business of tobacco farming in Zimbabwe and across the world reducing the profitability of the tobacco business. This has resulted in large sums of financial resources being invested in research aimed at controlling pests and diseases in different crops. In Zimbabwe millions of litres of pesticides have been pumped into the environment in an effort to control pests and diseases in flue-cured tobacco fields. There have also been efforts to incorporate inherent pest and disease resistance in the varieties of flue-cured tobacco developed in the country since the early 1940s. This paper is a review of the breeding efforts to incorporate pest and disease resistance in the elite flue-cured tobacco germplasm used to develop some of the popular varieties in Zimbabwe.

CTH144 is a new flue-cured tobacco (Nicotiana tabacum L.) hybrid recommended for commercial release in Canada. The cured leaf quality of CTH144 was superior to both check varieties Delgold and CT157. The yield potential of CTH144 was intermediate compared with the checks. As a result, the economic return of CTH144 is superior to both check varieties. CTH144 has resistance to Tobacco Mosaic Virus. CTH144 is adapted to the tobacco-growing areas of southwestern Ontario.

Field experiments were conducted to determine the effects of various densities of four fall-seeded small grain mulches and diphenamid (N,N-dimethyl-α-phenyl benzeneacetamide) on weed control, yield, and quality in no-till flue-cured tobacco (Nicotiana tabacumL. ‘McNair 944’). A greenhouse study investigated the effects of non-soil-incorporated mulch from the same small grains plus alfalfa (Medicago sativaL.) on various growth parameters of tobacco (‘Speight G-70’). None of the mulches used in the greenhouse study adversely affected growth of the tobacco. Mulch from rye (Secale cerealeL. ‘Abruzzi’) killed about 2 weeks before transplanting plus diphenamid provided better annual broadleaf weed control (85%) than wheat (Triticum aestivumL. ‘McNair’), barley (Hordeum vulgareL. ‘Keowee’), and no mulch. Oat (Avena sativaL. ‘Brooks’) mulch resulted in 80% broadleaf weed control. There were no differences in annual grass control (which was short lived) among mulches but control was lower in the no-mulch treatment. Rye mulch resulted in a 22% increase in the control of broadleaf weeds compared to no-mulch. Yield of the no-till tobacco did not differ among mulches and averaged 82% of that conventionally grown. The quality was not affected. The rye mulch did not affect the yield or quality of tobacco when compared to a nonmulch, noncultivated treatment. The 18% decrease in the no-till yield was apparently the result of the lack of tillage and increased weed interference and was not due to adverse effects from the rye.

ABSTRAK<br />Tembakau Temanggung merupakan komoditas penting bahan baku<br />industri rokok kretek, sumber pendapatan petani dan PAD Kabupaten<br />Temanggung. Selain itu, tembakau juga menjadi pemicu pertumbuhan<br />kegiatan ekonomi lainnya yang terkait dengan usahatani, seperti<br />transportasi, penyediaan sarana produksi pertanian serta penyediaan<br />lapangan kerja. Usahatani tembakau Temanggung menghadapi 3 (tiga)<br />masalah utama, yaitu: sifat tembakau Temanggung yang tergolong fancy<br />product, struktur pasar yang monopsonistik dan kondisi lahan usahatani<br />yang beragam (beragam menurut elevasi, arah lereng dan tingkat<br />kemiringan lereng). Kondisi lahan tersebut mengakibatkan mutu tembakau<br />menjadi beragam, dan cenderung menurun bahkan mengancam keber-<br />lanjutan usahatani tembakau. Penelitian ini dilaksanakan bulan Januari<br />2004 - Maret 2005 di sentra produksi tembakau Temanggung, yang<br />memiliki beberapa perbedaan berdasarkan elevasi, arah lereng dan tingkat<br />kemiringan. Untuk mengetahui ragam mutu dan produktivitas dianalisis<br />dengan sidik ragam. Untuk mengetahui pengaruh elevasi, arah dan<br />kemiringan  lereng  digunakan  analisis  regresi  berganda.  Dalam<br />menganalisis keberlanjutan usahatani, digunakan multi atribut non-<br />parametrik yang diolah dengan multidimentional scaling (MDS). Mutu dan<br />produktivitas tembakau Temanggung cukup beragam. Elevasi dan arah<br />lereng (slope aspect) merupakan faktor utama yang mempengaruhi mutu<br />dan produktivitas tembakau Temanggung. Mutu tembakau yang ditanam<br />pada lahan berelevasi di atas 1.000 m dpl, nyata lebih baik dibandingkan<br />dengan mutu tembakau yang ditanam pada lahan yang berelevasi kurang<br />dari 1.000 m dpl. Produktivitas tembakau yang ditanam pada lahan arah<br />lereng ke timur nyata lebih tinggi dibandingkan dengan produktivitas<br />tembakau pada lahan arah lereng ke timur laut dan utara. Tingkat<br />kemiringan lereng tidak berpengaruh terhadap mutu maupun produktivitas<br />tembakau. Indeks keberlanjutan usahatani tembakau Temanggung,<br />termasuk kedalam kategori cukup (IKb = 55,53 pada skala keberlanjutan 0<br />– 100).<br />Kata kunci : Tembakau, Nicotiana tabacum L., tembakau Temanggung,<br />mutu, produktivitas, indeks keberlanjutan, usahatani, Jawa<br />Tengah<br />ABSTRACT<br />Analysis of quality, productivity and sustainability and<br />development direction of tobacco farming in Temanggung<br />District, Central Java<br />Temanggung tobacco is an important commodity for cigarette<br />industry, farmers’ income and product domestic regional brutto (PDRB)<br />of Temanggung District. Tobacco stimulates economy activities, so that it<br />can grow other bussiness activities, such as transportation, agroproduct<br />and employment availability. Uncontrolled cultivation intensity and<br />market structure monopsonistic resulted in weak bargaining position of<br />farmer in marketing tobacco. Tobacco is a fancy product, it means that its<br />marketing and transaction are very determined by quality. These<br />conditions affected the sustainability of tobacco farm. This research was<br />carried out from January 2004 to March 2005 in the center of Temanggung<br />tobacco production, which varies in terms of elevation, slope aspect and<br />topography. Temanggung tobacco varies in terms of quality and<br />productivity. Elevation and slope aspect were the primary factors<br />influencing tobacco productivity and quality. The quality of tobacco<br />planted at farmer location at the elevation more than 1.000 m above sea<br />level (asl) with slope facing east, was significantly better than the quality<br />of tobacco planted at the elevation less than 1.000 m asl with slope facing<br />north-east and north. The tobacco productivity planted on the slope facing<br />east differed significantly with the tobacco productivity planted on north-<br />east and north slope facing. The slope did not significantly influence<br />tobacco quality and productivity. Sustainability index of tobacco farm<br />belongs to enough category (IKb = 55.53 at scale of sustainability 0 –<br />100).<br />Key words : Nicotiana tabacum L. Temanggung tobacco, quality,<br />productivity, sustainability index, farming system, Central<br />Java
