Abstract
The effect of nitrogen fertilization on growth and seed production was evaluated for Rottboellia exaltata L. f., and Solanum alatum MOENCH., at 0, 10, 20 and 40kg/10a. The results are summarized as follows:1. In Rottboellia the plant height decreased as the amount of nitrogen application was increased. The value was largest in the N-0 treatment at 90 days after seeding. In Solanum the plant lenght increased with increasing nitrogen application reaching a maximum in the N-40 treatment at 100 days after seeding (Fig. 1).2. In Rottboellia the total dry weight started increasing rapidly at 30 days after seeding but the increase became less at 90 days after seeding. The value was largest in the N-20 treatment at 120 days after seeding. In Solanum the total dry weight started increasing rapidly at 60 days after seeding and then started decreasing at 90 days after seeding. The maximum value was reached in the N-20 treatment at 90 days after seeding (Fig. 2).3. In both Rottboellia and Solanum, the dry weight percentage allocation of spike, fruit and flower increased at higher nitrogen levels, while the dry weight percentage allocation of root, stem and leaf decreased as the amount of nitrogen application was increased (Fig. 3).4. In Rottboellia the leaf area increased with increasing nitrogen application reaching a maximum in the N-20 treatment at 120 days after seeding. In Solanum the leaf area reached a maximum in the N-40 treatment at 90 days after seeding and then decreased at a fast rate (Fig. 4).5. In Rottboellia heading was delayed slightly in the N-40 treatment and in Solanum flowering was delayed significantly in the N-40 treatment. In both Rottboellia and Solanum the values of spike, fruit and flower were largest in the N-20 treatment (Table 1).
