Abstract

In field trials during kharif 1971, E. coracana E.C. 4840 and Purna yielded 5.25 and 4.73 t grain/ha, respectively. Grain yields/plant were 15.85 and 13.65 g. Differences in grain yield were due to significant differences in ear number/plant and grain weight/ear. In both cultivars the chances that a tiller would bear an ear decreased the later the tiller appeared. In E.C. 4840 all the main axes shoots produced ears, while 96% of the earliest, 85% of the intermediate and none of the late and 73% of the secondary tillers produced ears. In Purna all the main axes produced ears and the corresponding figures for the other tillers were 93, 71, 50 and 94%. The ear plus peduncle provided 23.5% of the photosynthetic contribution to the grain, 36% came from the flag-leaf lamina and sheath and 40.5% from parts below the flag leaf. The contribution from leaves below the flag leaf decreased from 12.5% from the 2nd + 3rd leaf to 2.5% from the 8th + 9th leaf. The contribution from flag leaf lamina and sheath was 40% in E.C. 4840 and 32% in Purna. Mean DM accumulation/plant, LAI at ear formation and RGR were highest in Purna and NAR was highest in E.C. 4840. Grain yields at spacings of 22.5 X 7.5 and 22.5 X 15 cm were 5.44 and 4.54 t/ha, respectively, and were 4.74, 5.11 and 5.13 t/ha with 75, 100 and 125 kg N/ha
