33. Barley, lentil, and flax yield under different intercropping systems.

Agronomy J., 82, 1990, pp. 1066-1068

This study was conducted to determine the productivity of intercrops, barley + lentil and barley + flax as compared to monocrops of barley, lentil and flax as influenced by the level of irrigation and mulch.

Six-rowed barley (Hordeum vulgare L.) was intercropped with lentil (Lens culinaris Medik) and flax (Linum usitatissimum L.) with two levels of irrigations [(i) zero and (ii) one irrigation applied 35 d after planting] and two levels of mulch [(i) no mulch and (ii) rice straw mulch at the rate of approximately 7 Mg/ha-1]. Monocrop of each species were also grown.

Information on intercropping of barley with lentil and flax is very limited. Barley, lentil and flax are grown under rainfed conditions with limited water supply. Productivity per unit area could be increased through the use of suitable crops with higher yield stability and appropriate intercropping. In the winter dry season the amount of irrigation water available is very limited and in some areas only a single irrigation may be available. Limited irrigation of crops like barley, lentil, flax and conservation of water with mulches may make the difference between an uneconomical and an economical crop yield.

In this study the seed yield of the monocrops were higher than their intercrop yields. Intercropped barley yielded 73 to 81% of the yield to monoculture. Intercropped lentil yielded 30 to 34% of the yield of monoculture, whereas intercropped seed yield of flax ranged from 27 to 31% of monoculutre. Yield increased from one application of irrigation ranged from 12 to 21% of zero irrigation. The increase in yield due to straw mulch was 11 to 17% higher over no mulch. The barley-lentil intercrop recorded higher values of land equivalent ratio (LER) and monetary advantage (MA), and had higher intercropping advantage of area time equivalent ratio (ATER) than the barley-flax intercrop.

This study indicated that in areas having no irrigation, straw mulch could be utilized for conservation of soil moisture which can increase yields of crops like barley, lentil and flax. One irrigation along with straw mulch was found to be the best for all these crops. Barley + lentil intercropping was preferable to barley + flax intercropping in the study area.
