Abstract
Kabuli chickpeas (Cicer arietinum L.) were sown on 3 July and 30 September 1992 into a Templeton silt loam soil. Nitrogen at 0, 15, 45 and 90 kg/ha and Rhizobium inoculation at 0 and 2 times the recommended rate were applied in a factorial design. Data were collected from plots which had received 0 and 45 kg N/ha and on those which had received 0 and twice the recommended rate of inoculant. Seed yield averaged 305 g/m2• Nitrogen did not increase seed yield, but it did significantly decrease mean seed weight. In the July sowing inoculated plants which had not been treated with nitrogen produced 423 g/m2 of seed. Inoculation increased mean seed yield by 44% through increasing the number of pods/plant and seeds/plant. Yield development was affected by sowing date. At one month after flowering plants from the early sown plots had 38% more pods than in the late sowing. However, the early sowing had a large decline in pod number from two months after flowering (41.9 pods/plant) to harvest (31.3 pods/plant). The late sowing had no such decline and had 26.1 and 30.0 pods/plant respectively at the equivalent dates. The only factor which affected phenological development was sowing date. The early sowing flowered at 139 days while the late sowing took only 72 days to flower. Potential yield sites at 50% flowering were affected by the treatments, with 45 kg N/ha producing 8.8 flowering nodes/plant while 0 kg N!ha plants had only 6.3. The early sowing also had a significantly higher number of flowering nodes (9.0) than the late sowing (6.1).
