An investigation was carried out during summer season of 1978 and 1979 at the vegetable Research Farm, Department of Horticulture, Faculty of Agriculture, Banaras Hindu University of Varanasi to study the effect of nitrogen, phosphorus, potassium and different plant spacing on the growth and yield of muskmelon variety Jaunpuri Application of nitrogen, phosphorus and potassium increased the length of main creeper, number of leaves in main creeper, number of sub-creeper and fruit weight and yield. Application of 100 kg N/ha, 60 kg P/ha and 60 kg K/ha gave the highest vegetative growth, fruit weight and yield, whereas the closest plant spacing (60 cm) showed highest yield. The wider spacing failed to compensate the loss incurred due to less plant population though it had increased the yield offiuitsper plants. Consequently the yield of fruits/ha was in closer spacing as compared to wider spacing.
