18. Effect of mixed cropping lentil with barley at different seeding rates.
LENS (Newsletter), 1991, pp. 24-26
The experiment explained in this paper was conducted to determine a suitable seeding ratio for lentil and barley sown in a random mixture.
In a mixed cropping experiment, three combinations of lentil (Lens culinaris Medik.) and barley (Hordeum vulgare L.) were compared to corresponding sole crops.
The experiment was conducted under rainfed conditions.
The treatments consisted of three combinations of lentil and barley (100:10, 100:30, and 100:50) plus the monocultures of the two crops as checks. The design was randomized complete block with five replications.
The results of this study revealed that yield and yield parameters of lentil were lower in mixture with 50% barley than in monoculture. Grain yield, plant populations/m2, number of pods/plant, number of seeds/pod, and 1000-seed weight of lentil in mixed cropping were statistically identical to sole lentil (1.05 t/ha) up to addition of 30% barley seeds.
Due to higher competition of nutrients, moisture, space, and light, the number of pods/plants, number of seeds/pod, and seed size, i.e., yield/plant of lentil were reduced.
Grain yield and number of spike/m2 of barley differed significantly mainly due to different amount of seeds used in the combinations. Sole barley produced highest grain yield (2.58 t/ha) and the highest number of spikes m2. In mixed cropping, the yield/plant of barley was significantly higher over sole barley, as were the yield components, i.e., number of spikes/plant, number of grains/spike, and 1000-grain weight. The increase in yield/plant might be for beneficial effect of lentil on barley.
Relative yields of barley showed that barley yields were higher than the expected yields (on the basis of seeding percentage) in the mixtures.
That is 10%, 30%, and 50% barley seeds produced 11%, 36%, and 51% yield of monoculture, respectively.
From the above results, it may be concluded that 30% barley seed did not reduce lentil yield significantly, producing highest LER of 1.29.
Highest monetary return was also obtained from the same combination.
Summarizing, it may be stated that 30% barley seeds can be mixed in normal lentil without substantial yield loss and with high monetary return in the region.
