Effect of nitrogen application on flowering and yield of eggplant (Solanum melongena L.)

Effect of nitrogen application on number of flowers per plant, number of different types of flowers per plant, length of style, number of fruits per plant and fruit yield/ha of eggplant was investigated under controlled greenhouse conditions. Nitrogen was supplied at 50, 75, 100, 125, 150, 175 and 200 kg N/ha with one control (no nitrogen) treatment. Nitrogen supplied at 200 kg N/ha gave best results and significantly produced the highest number of flowers per plant, fruits per plant and yield (32.24 ton/ha) over control plants. Nitrogen failed to influence style length and type of flowers i.e. long, medium, pseudo-short and short styled flowers. Nitrogen application at 150 and 175 kg N/ha showed comparable results with nitrogen applied at 200 kg N/ha.
