Response of Brinjal (Solanum Melongena L.) To Nitrogen Phosphorus and Potassium Fertilization with Different Plant Spacings

Response of brinjal var. Pusa Purple Long to different plant spacing (60 x 30, 60 X 50, 75 X 50, 75 x 70 and 75 x 90 cm) and graded levels of nitrogen (0 to 180 kg N/ha), phosphorus (0, 30 and 60 kg P/ha) and potassium (0, 30 and 60 kg/ha) was studied on sandy loam soil, slightly acidic in reaction, low in nitrogen and available phosphorus content and rich in available potassium content during summer seasons of 1973, 1974 and 1975 at the Indian Institute of Horticultural Research, Hessaraghatta, Bangalore. Application of nitrogen and phosphorus increased plant height, fruit size and fruit yield. Plant spacing of 75 x 50 cm gave highest yield. Yield response of brinjal to nitrogen and phosphorus fertilization varied with plant spacing. However, maximum and optimum yield were highest at 75 x 50 cm plant
