“…This highlights that spring wheat added at a low density (17% of sole crop density) was still dense enough to decrease the associated lentil yield, illustrating strong interspecific competition of spring wheat with lentil. Similar trends were observed in several previous studies of lentil-wheat intercrops (Akter et al 2004;Carr et al 1995;Wang et al 2013). Actual yield of lentil in sole crop and intercrop was significantly higher in 2016 than in 2015 (P < 0.001 and P < 0.01, respectively) ( Fig.…”

“…4a) was higher in intercrop than in sole crop, non-significantly in 2015 (28 vs. 23 cm, respectively; P = 0.23) but significantly in 2016 (36 vs. 25 cm, respectively; P < 0.01). Akter et al (2004) observed a similar increase in lentil height in intercrop. Mean lentil height at harvest in intercrop was lower in 2015 than in 2016 (P < 0.05), while no difference was observed in sole crop (P = 0.38).…”

“…Thus, intercrops with lentil can achieve high, albeit lower, actual gross margins, even with a strong decrease in the actual yield of lentil. Akter et al (2004) observed an economic advantage in the actual yield of lentil-wheat intercrops for management strategies including irrigation, fertilisation and chemical control of biotic stresses. However, since lentil is intended to human food and harvested with combine harvesters, one should include the potential grain losses due to non-edible seeds (e.g.…”

“…Lentil grains are then separated from wheat grains using successive separating and cleaning tools such as vibratory, rotary, gravity and optical sorters. Like other legume-cereal intercrops, intercrops of lentil and wheat may be an interesting way to increase lentil production, as they have been shown to increase total yield (Akter et al 2004;Carr et al 1995) and gross margin (Akter et al 2004).…”

Lentil has been overlooked by organic farmers in Europe mainly because of low and unstable yields, notably due to lodging and bruchid beetles. Our study aimed to evaluate the efficiency of lentil-spring wheat intercrops to lower these reducing factors and increase yield and gross margin. A 2-year field experiment was carried out in southwestern France in 2015 and 2016 under organic farming rules. Four lentil and two wheat cultivars were grown as sole crops and intercrops. The "yield gap" concept was adapted to include grain losses due to mechanical harvest and insufficient quality. Mean total intercrop grain yield before mechanical harvest was higher than mean sole crop (1.91 ± 0.47 vs. 1.57 ± 0.29 t ha −1 , respectively), with a lower mean yield of lentil in intercrop than in sole crop (1.06 ± 0.28 vs. 1.61 ± 0.54 t ha −1). This led to a lower mean gross margin of intercrop than that of sole cropped lentil (1772 ± 507 vs. 2371 ± 756 € ha −1), before mechanical harvest. The percentage of bruchid-damaged grain did not differ significantly between intercrop and sole crop (41%). However, lentil lodging was lower in intercrop than in sole crop (15 vs. 40%), which strongly increased lentil mechanical harvest efficiency (75 vs. 50%). This led to a similar mechanically harvested yield of lentil in intercrop and sole crop (0.80 t ha −1). Consequently, mean marketable gross margin of intercrops was higher than that of sole cropped lentil (949 ± 404 vs. 688 ± 393 € ha −1), due to the addition of marketable wheat yield. We thus demonstrated for the first time the interest of extending the yield gap concept to consider all grain losses that influence profitability, including those linked to mechanical harvest efficiency and insufficient grain quality. Furthermore, this is a first demonstration of the higher profitability of organic lentil-wheat intercrops compared to sole crops despite the additional costs associated with grain sorting.

“…Sowing mixtures of varieties can be an important element of organic cropping of lentil. Compared to sole cropping, this cultivation method can contribute to a better use of space in crop, reduce the spread of fungal pathogens, and increase yield stability when adverse conditions occur during the growing season [16].…”

A field study was conducted at the Certified Organic Farm in Poland over the period 2014–2016. This study evaluated weed infestation and seed yield of the lentil varieties ‘Tina’ and ‘Anita’, as well as of a mixture of these two varieties, sole cropped and row intercropped with naked oats as a supporting crop. Additionally, lentil was sown at a different row spacing of 20 and 25 cm. The lentil variety ‘Anita’ produced 25.3% higher yields than var. ‘Tina’. Weight of 1000 seed, number of pods per plant, and first pod height did not differ significantly in the treatments with the lentil varieties. The lentil seed yield obtained in the treatments with a supporting crop was lower by 9.4% compared with the sole cropped plots. In turn, the 1000 seed weight was 3.9% higher in the treatment where a supporting crop was used. The presence of oats as a supporting crop in lentil crop allowed crop competitiveness against weeds to be increased significantly, thus reducing their total number and dry weight by 5.3% and 30.5%, respectively. Sowing lentil at different row spacings did not have a significant effect on seed yield and weed infestation in crop. The greatest diversity of weed species was found in the treatments where the mixture of the lentil varieties was sown and in the treatment with the smaller row spacing. Intercropping of lentil with oats resulted in reduced occurrence of monocotyledonous weeds such as Echinochloa crus-galli and Elymus repens. The presence of oat as a supporting crop can effectively reduce the pressure from weeds without significantly reducing lentil cultivar yield in organic farming.

Wheat (Triticum aestivum L.)–cotton (Gossypium hirsutum L.) relay strip intercropping involves cultivating wheat sown in autumn and cotton sown in spring, allowing the two crops to grow together for ∼2 months. Despite its prevalence in cotton‐growing regions globally, this agricultural practice remains untapped in Turkey, where the emphasis on resource use efficiency and the competition between staple and cash crops are paramount. To address this, we conducted a study comparing three cropping systems under both well‐watered and limited water conditions: sole wheat with a row spacing of 13.5 cm, sole cotton with a row spacing of 70 cm, and an intercropping system consisting of four rows of wheat and two rows of cotton, with row spacings of 13.5 cm and 40.5 cm, respectively. In intercropped wheat and cotton, the relative wheat yield was 0.68, while the relative cotton yield was 0.73, resulting in a combined relative yield of 1.41 when compared to monoculture. The land equivalent ratio (1.44) and area time equivalent ratio (1.08) consistently exceeded 1.0, particularly under limited watering conditions and concurrent heat stress observed in the second year of the experiment. Our findings indicate that wheat–cotton relay intercropping holds significant potential as a highly effective approach to enhance the production of both cotton and wheat in Turkey, particularly in stressful conditions such as limited water availability.
