Partitional Analysis of Grain Yield from Different Shoots as Influenced by Nitrogen in Finger Millet1
- K. Krishnamurthy2
Pattern of grain yield contribution from different tiller groups in relation to nitrogen levels was investigated in finger millet (Eleusine coracana L. Gaertn, var. ‘H-22’) in a 2-year field trial. There was linear increase in grain yield (7 to 26 g/plant) with increasing levels of nitrogen (0 to 90 kg/ha). These differences in grain yield were mainly related to the total number of shoots produced (4.0 to ll.9/plant), and particularly to those produced during the first 27 days (2.1 to 8.7/plant). Nitrogen also increased the grain yield contribution (38 to 52%) from the early season tillers. The final grain yield and the number of shoots produced within 5 weeks of transplanting were related. The main axis contributed 24%, whereas early, intermediate, late, and secondary tiller groups provided 47, 16, 8, and 5%, respectively, to the total grain yield per plant (17 g). In a similar manner, these groups of shoots contributed 15, 40, 21, 14, and 10%, respectively, to total ear number per plant (6.9).Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
