“…Although all arable C 3 crops tend to have a similar photosynthetic eciency, dierences may occur when growth conditions become unfavourable. For example, photosynthetic eciency was reduced by moisture stress in pea (Heath and Hebblethwaite 1985). Semilea¯ess pea cultivars like Pro® and Juno have a tendency to build up a canopy with a higher light transmission (Kimpel-Freund et al 1998).…”

On a brown warp soil (Fluventic Eutrochrept) near Goettingen, Germany, conventional leafed pea (Pisum sativum L. cvs Messire and Bohatyr) and semileafless types (cvs Profi, Juno and Azur) were grown in mixed stands together with oat (Avena sativa cvs Alf and Lutz) in substitutively designed experiments from 1995 to 1997. Oat was the dominant component. Crowding coefficients for oat averaged 7.4. No relationship could be detected between the crowding coefficient of oat and any yield advantage from the mixture. Crowding coefficients for pea varied substantially, between 0.1002 (Juno and Alf in 1996) and 0.2979 (Bohatyr and Alf in 1996). Crowding coefficients for semileafless pea cultivars were smaller than for conventional leafed types. The yield advantage of the mixture increased as the crowding coefficient of pea increased. The maximum yield increase for the mixture was achieved when the relative yield total (RYT)=1.17 or + 11 dt grain DM ha–1 for mixtures of the long‐strawed conventional leafed cultivars Bohatyr and Alf (in 1996). The crowding coefficients of pea were positively correlated with the level of symbiotically fixed N2 in the mixed stands. When N2 fixation with mixed cropping was about 30 kg N ha–1, RYT was unity. Increasing symbiotic N2 in the mixtures resulted in increasing yield advantages in the mixture. Short‐strawed pea cultivars seem unsuitable for mixing with oat. Plant height of pea appeared to be more important than plant leaf type. Accordingly, mixtures containing the long‐strawed semileafless pea cultivars Profi and Alf were more successful. It is concluded that increased competitiveness of the pea component in the mixture with oat entails increasing the level of symbiotic N2 fixation including resource complementarity and thus yield advantage in the mixed stands.

“…The very low LAI (2.2, below the critical LAI) in combination with a low total intercepted PAR in shaded unirrigated plants gave the lowest TDM among all the treatments. Increased DM production with increased radiation interception has been reported in chickpeas (Hernandez 1986), lentils (McKenzie & Hill 1991), peas (Heath et al 1994), field bean (Husain et al 1988), and mung beans (Liyanage & Me William 1981). Virtually all of the effects of these treatments on DM production are the result of reduced radiation interception and not to reduced efficiency of production of DM from intercepted radiation.…”

An experiment was conducted in 1994-95 to test the effects of soil moisture (two levels, nil and fully irrigated) and shade (two levels, full light and 40% shaded) on the abortion of reproductive structures, yield, and yield components in chickpea (Cicer arietinum L.). Shade and soil moisture interacted significantly, and the highest dry matter (DM) production of 838 g/m 2 was produced by unshaded irrigated plants. This was about twice the DM produced by shaded unirrigated plants. Total DM production was highly correlated with radiation interception, where c. 2.1 g DM were produced per MJ of intercepted photosynthetically active radiation (PAR). Functional growth analysis showed that the crop growth rates were 14 and 27 g/m 2 per day for shaded and unshaded plants respectively. The two factors again interacted on seed yield. Highest yields were produced from plants that were unshaded and irrigated (389 g/m 2 ), whereas shaded irrigated plants produced only 139 g/m 2 . Reduced seed yield was accompanied by a large drop in harvest index (HI) in shaded irrigated plants. This drop in HI was because of a limited assimilate supply in shaded plants and increased reproductive abortion in shaded and irrigated plants.

“…Die Kornerträge der normal beblätterten Erbsensorte Messire und der halbblattlosen Sorte Profi waren in den Reinsaaten nicht wesentlich verschieden. Es ist bekannt, daß sich die halbblattlosenErbsensorten trotz fehlender Fiederblättchen imHinblick auf die Photosyntheseleistung undLichtinterzeption oft nicht von normal beblätterten Sorten unterscheiden ( Heath et al 1994, Kimpel‐Freund et al 1998). In den Gemengen war dennoch die Tendenz zu erkennen, daß die Sorte Profi durch den Hafer stärker zurückgedrängt wurde als die Sorte Messire.…”

Competition and yield advantage in mixtures of pea (Pisum sativum L.) and oats (Avena sativa L.) In field trials on a fertile fluvisol in 1995 and 1996 near Göttingen, Germany, pea (Pisum sativum; cv. Messire/conventional leafed, cv. Profi/semileafless) and oats (Avena sativa; cv. Alf) were grown as sole crops and in substitutive mixtures. The sole crops were established at 80 pea seeds m−2 and 300 oat seeds m−2. The mixtures consisted of 67 % (pea) and 33 % (oats) of the monoculture densities, respectively. Interactions of cv. Messire or cv. Profi and oats were similar in 1995 and 1996. The mixtures outyielded the monocultures with respect to total above ground dry matter (RYT = 1.15) and grain yield (RYT = 1.09). Grain yield of pea and oats averaged 4.9 t ha−1 in monocultures and 5.5 t ha−1 in mixtures. Oats was relatively the stronger of the two competitors. Decreasing number of pods per plant could be highlighted as the factor for a lower pea seed frequency in the yield of the mixtures. For oats the number of panicles per plant and kernels per panicle were higher in the mixtures compared with the oat monocultures. The average amount of the harvest index (HI) was 0.52 for pea and 0.46 for oats. Favourable growth conditions increased HI values however, prolific vegetative growth in the mixtures resulted in lower HI values. The predicted RYT‐values estimate the maximum combined grain yield of 6.3 t ha−1 in the mixture of 87 % pea (70 seeds m−2) and 13 % oats (39 kernels m−2).
