Abstract

Summary A two year study on ‘Pusa Sawani’ okra grown during the summer in Rampur, Nepal (228 m OD; 27° 37′ N) has shown that spacing did not affect days to first harvest or pod length but that pod number plant −1 was affected significantly. Although individual plant yields at each harvest were maximum viith plants spaced 45 cm apart (a population of about 50,000 plants ha −1 ) pod yields ha −1 were maximum with plants spaced only 15 cm apart (about 150,000 ha −1 ). Applications of nitrogen fertilizer hastened the first harvest by 4–6 days compared to the unfertilized control plots. The greatest pod yield (9.3 t ha −1 ) was obtained from plots given 60 kg N ha −1 .
