“…One of the main challenges for lentil cultivation is increasing its yield, which in Germany currently ranges from 0·5 to 0·8 t/ha under farmers’ practices. This is much lower than the 1–2 t/ha in, for example, Turkey, Canada and Australia (Tepe et al 2005; McDonald et al 2007; Baird et al 2009).…”

SUMMARYThe present study examined variation in sowing date on lentils (Lens culinaris) in a standard lentil–barley (Hordeum vulgare) mixed cropping system in the temperate climate of central Europe to determine the effect on crop yield and weed control. A 2-year (2009/10) field experiment was carried out at the organic research station Kleinhohenheim (KH) and at the conventional research station Oberer Lindenhof (OLI) of the University Hohenheim, southwest Germany. The crop was sown at three dates in the period from March to May. Grain yield was significantly higher at the earliest sowing both for lentils (3·0 t/ha at KH, 2·4 t/ha at OLI) and barley (1·2 t/ha at KH, 2·6 t/ha at OLI). Weed biomass at KH increased significantly with delayed sowing and was independent of lentil genotype, whereas sowing date had no significant effect on overall weed biomass production at OLI. Unlike weed biomass, weed density generally decreased significantly with delayed sowing at OLI. The results indicate that early sowing can increase the yield of lentils, and can be used as an indirect method of weed control in some organic farming systems.

“…Competitive ability of a crop can be used as an important tool in integrated weed management [21,[25][26][27]. Crop species even varieties of the same species differ in their ability to compete for resources [14,20,[28][29][30]. Among the wheat varieties studied in this research, BARI gom 27 allowed the minimum weed growth while BARI gom 21 allowed maximum weed growth.…”

Weed is one of the major pests of wheat causing substantial yield losses and hence sustainable weed management is a huge challenge for its cultivation. Weed competitive crop variety is considered to be a vital and eco-friendly tool for integrated weed management. Therefore, it is necessary to evaluate the weed competitiveness of the available Bangladeshi wheat germplasms for their possible inclusion as a component of integrated weed management. The present research was designed to evaluate the weed competitiveness of ten recently released wheat varieties of Bangladesh by growing them under weedy and weed-free conditions. Plots without wheat (weed monoculture) were also maintained. The experiment was carried out in a randomized complete block design and replicated thrice. Results showed that wheat varieties varied widely in their weed competitiveness and yielding ability. Among the wheat varieties studied, BARI gom 27 allowed the minimum weed growth (87.0 gm -2 ) while BARI gom 21 allowed maximum weed growth (188.9 gm -2 ). Grain yield ranged between 1.9 t ha -1 (BARI gom 23) and 3.7 t ha -1 (BARI gom 24) under weed-free condition, and between 1.3 t ha -1 (BARI gom 21) and 2.9 t ha -1 (BARI gom 28) under weedy condition. Weed inflicted relative yield loss ranged from 17.8 to 51.2% among the varieties. Although BARI gom 24 was the highest yielder but its competitive ability against weed was very poor. On the other hand, BARI gom 28 and BARI gom 30 appeared as the most weed competitive varieties (17.8 and 24.9% relative yield losses, respectively) with moderate grain yield. BARI gom 30 was the best in terms of yield, but BARI gom 28 ranked first in terms of weed competitiveness. Therefore, considering high feasibility of growing weed competitive variety as a tool for sustainable weed management, breeding for strongly weed competitive wheat variety with high yield potential is necessary.

“…We did not observe differences between cultivars in their response to weeding. Although lentil cultivars vary in their growth habits (Saxena, 2009), McDonald et al (2007) and Tepe et al (2005) indicate that cultivar selection alone is not effective in improving the competitiveness of a lentil crop (Sultana et al, 2005).…”

Field peas (Pisum sativum L.) and lentils (Lens culinaris Medik.) are high protein food crops for potential use in organic rotations. We determined the eff ects of cultivar selection, delayed sowing, and weed removal on yield of spring-planted fi eld peas and lentils grown using organic methods. In 2009 and 2010, at three southern Minnesota locations, two lentil cultivars (Crimson and Pennell) and four yellow fi eld pea cultivars (DS Admiral, Commander, Yellow, and Miami) were planted on three planting dates (18 April, 28 April, and 10 May) and grown with and without weed control. Yields of Crimson lentil were 66% higher on average than those of Pennell lentil. Pea cultivars had similar yields. Yields of peas planted on 18 April were 23 and 71% greater than yields for peas planted on 28 April, and 10 May, respectively. Yields of lentils at the early date were 50 and 120% greater than those at the middle and late dates, respectively. Weed removal increased pea yields by an average of 63% and lentil yields by an average of 87%. Both weeded and unweeded pea and lentil yields were higher with early planting. Delayed planting was ineff ective in reducing weed biomass. Field pea reliably produced yields suffi cient to off set production costs in both low-price commodity and high-price direct marketing scenarios. Lentil yields did not consistently exceed economic break-even levels in most environments. Field pea is a profi table crop for organic systems when early planted and when weeds are controlled.
