  To investigate the effect of split application of nitrogen on cotton yield and its components for medium stapled commercial cotton (Gossypium hirsutum L.) variety MNH554, a field trial was carried out at Cotton Research Station, Multan during 1998 to 2000. Ten nitrogen levels viz., 0, 56, 84, 112, 112, 140, 168, 168, 196 and 224 kg N ha-1 were tested in Randomized Complete Block Design having three replications. Nitrogen was applied in split doses at planting. Ist irrigation, flowering and boll fermentation. 56 kg P2O2 ha-1 was also applied as a basal dose . N168 kg ha-1 proved superior over others when split applied in three equal doses i.e., 56, 56, 56 kg N ha-1 at Ist irrigation, flowering and boll formation stages. This produced a significant increase in plant height, bolls per plant, boll weight and seed cotton yield. On the average of three years 168 kg N ha-1 gave 212.8% increase in seed cotton yield over O.N.

  An experiment was conducted to assess the effect of sowing date on two cotton varieties MNH552 and MNH554 grown on Ist April, 15th April, Ist. May, 15th May, Ist. June, 15th June, Ist. July and 15th July during 1998 and 1999 under Multan conditions. 15th May and Ist June sown cotton displayed significantly maximum seed cotton yield of 2998 and 2883 kg ha-1 in 1998 and 4027 and 3894 kg ha-1 respectively in 1999 as compared to 595 and 253 kg ha-1 (1998) and 1269 and 223 kg ha-1 (1999) from crop sown on Ist and 15th July respectively. The increase in both sowing dates in seed cotton yield was associated with boll weight and bolls per plant. On average of two years data 15th May produced highest seed cotton yield of 3513 kg ha-1, whereas the lowest figure was 238 kg ha-1 (15th July). Comparing varietal performance MNH552 (2310 kg ha-1) yielded higher as compared to MNH554 (2288 kg ha-1). However two cultivars declined the yield in late planting.
