“…Researchers report the advantages of various intercropping managements such as pea with wheat against weeds (Szumigalski & van Acker, 2005), pea with barley (Hauggaard-Nielsen et al, 2006), and pea with oats (Rauber et al, 2001). Diversity of weeds was decreased in intercrops in comparison with sole crop (Gharineh & Moradi Telavat, 2009). Like cultivated plants, weeds obtain nutrients through root uptake from the soil solution.…”

et ctr is a neglected theme in agricultural research. Weeds continue to play a major limiting role in agricultural production. The control of weeds using classical pesticides raises serious concerns about food safety and environmental quality, which have dictated the need for alternative weed management techniques. The field experiments were carried out in 2007-2010 at the Institute of Agriculture (Dotnuva, loamy soil) and the Joniskelis Experimental Station (Joniskelis, clay loam soil,) of the Lithuanian Research Centre for Agriculture and Forestry. The aim of this study was to determine the effect of intercropping pea with spring cereals on crop competition, yield performance and weed control in organic farming conditions. The following trial design was used for intercrops and sole crops: 1) pea (cv. 'Pinochio'), Ps, 2) pea/spring wheat (Triticum aestivum L. emend. Fiori et Paol., cv. 'Estrad'), PWi, 3) pea/spring barley (Hordeum vulgare L., cv. 'Aura'), PBi, 4) pea/oats (Avena sativa L., cv. 'Migla'), POi, 5) pea/spring triticale (× Triticosecale Wittm., cv. 'Nilex'), PTi, 6) spring wheat, Ws, 7) sprig barley, Bs, 8) oats, Os, 9) spring triticale, Ts. The experimental plots were laid out in a complete one-factor randomised block design in three replicates. Individual plot size was 2.5 × 12 m. The intercrop design was based on the proportional replacement principle, with mixed pea grain and spring cereals grain at the same depth in the same rows at relative frequencies (50:50-a relative proportion of grain legume and spring cereals seeds). Wheat seeds rate were 5.5, barley 4.7, oat 6.0, triticale 4.5 and pea 1.0 mln seeds ha-1 for sole crop. Weeds were assessed twice: at stem elongation growth stage (BBCH 32-36) and at development of grain filling growth stage (BBCH 73). Mass of weeds and botanical composition was determined in 0.25 m 2 at 4 settled places of each treatment. The experimental data were processed by the analysis of variance and correlationregression analysis methods using a software package "Selekcija". Weed number and mass data were transformed to 1 x + .

“…In India, chickpea is generally intercropped with wheat, barley, lentil, pea, mustard, linseed, safflower and coriander. Selection of crops for intercropping includes their compatibility with main crop, low competition for resources and ability to produce higher yield (Gharineh and Telavat 2009). The experiment was under taken during rabi season of 2017 and 2018 with the objective to find out the effect of different intercrops on chickpea and evaluate the productivity and economic viability of bed planted chickpea based intercropping systems.…”

Background: Chickpea (Cicer arietinum L.) is the third most important pulse crop produced after dry bean and peas in the world. Amongst pulses, chickpea is the major crop in India but for international market the quality of this crop has to be improved which may be possible by evaluation of different planting techniques. No systematic research and adequate technologies have been reported in Punjab on intercropping of different crops in chickpea. The current study aimed to find out the effect of different intercrops on growth and yield of bed planted chickpea based intercropping systems.Methods: A field experiment was carried out during the rabi season of 2017 and 2018 to evaluate the productivity and economic viability of bed planted chickpea based intercropping systems.The experiment was laid out in a randomized block design consisting of four replications with thirteen treatments.Result: Results showed that sole chickpea recorded highest seed yield and it was statistically at par with seed yield that obtained under chickpea + oats fodder (2:1), chickpea + oats fodder (4:1) and chickpea + linseed (4:1) intercropping systems. However, oilseed rape and barley as intercrops showed adverse effect on yield and yield attributes of chickpea. Chickpea + oats fodder in 2:1 row ratio recorded highest chickpea equivalent yield of 24.07 and 24.77 q/ha and system productivity of 15.96 and 15.60 kg/ha/day during 2017 and 2018, respectively. Higher net returns (Rs. 63098 and 70924/ha), benefit cost ratio (1.47 and 1.63) and production efficiency (417.9 and 446.1 Rs/ha/day) were also recorded in chickpea + oats fodder (2:1) intercropping system over sole chickpea (Rs. 44862 and 53769/ha and 1.21 and 1.41) during both the years. Chickpea + oats fodder (4:1), chickpea + linseed (2:1) and chickpea + linseed (4:1) also recorded significantly higher chickpea equivalent yield, net returns and benefit cost ratio as compared to sole chickpea.

Species Choice Influences Weed Suppression, N Sharing and Crop Productivity in Oilseed Rape–Legume Intercrops

Increasing crop trait diversity in oilseed rape (OR, Brassica napus L.) cropping systems by introducing frost-sensitive legume species could improve weed suppression and crop productivity. Intercrops and sole crops were compared over two years in the field in Western France. Winter OR was intercropped simultaneously with either spring faba bean (Vicia faba L.) or common vetch (Vicia sativa L.) in a row replacement design without herbicides. Each species was sown at 50% of the recommended sole crop density in alternate rows. Due to the high values of faba bean aboveground traits (height, leaf area, and biomass) and the strong competitive ability for soil N of OR, both species appeared complementary in resource utilization, and thus less soil N and light were available for weeds. The OR–faba bean intercrop was able to reduce weed biomass by 41% compared to the OR–common vetch intercrop. Furthermore, growth and competitive ability of OR for soil N were increased when intercropped with faba bean. Both grain yield and number per plant were three times higher in OR–faba bean intercrops compared to OR sole crops. Under high weed infestation, the presence of faba bean with OR reduced weed aboveground biomass by 35% and weed N accumulation by 11% compared to the OR sole crop. No change was observed in the weed community composition. We observed that a level of aboveground biomass greater than 2 t ha−1 and a soil N uptake at approximately 80 kg ha−1 was needed to reduce biomass and N content of weeds.
