Item Effect of different plant densities on sunflower varieties in red loam soils(Kerala Agricultural University, 1978) Salam, M A; Sadanandan, N; Nair, K P M; Mohamed Kunju, UAn experiment was conducted at the College of Agriculture, Vellayani to study the effect of different spacings on the yield of sunflower varieties. The results revealed that closer spacing decreased the head diameter and number of seeds per head, but significantly increased the total yield of seed. Closer spacing of 30x20 cm gave a maximum yield of 2163.1 kg seeds per hectare. The varieties did not show any difference in yield potential.
