A study was conducted during Rabi season of 2015-16 and 2016-17 at the Research Farm of ICAR-NRC on Seed Spices, Ajmer, Rajasthan to assess the influence of plant geometry and different levels of nutrition on vegetative growth and yield of coriander variety Ajmer Green Coriander-1 (AGCr-1). The treatments comprised of three crop geometry (25 cm x 5 cm, 25 cm x 7.5 cm and 25 cm x 10 cm) and three levels of NPK (40:25:20 kg ha-1, 50:35:25 kg ha-1 and 60:45:30 kg ha- 1) laid out in Randomized Factorial Block Design. The vegetative growth attributes viz., plant height at different growth stages, length of first leaf, length of second leaf, number of basal leaves plant-1, primary branches plant-1 and secondary branches plant-1 recorded the highest level with the application of 60:45:30 kg ha-1 NPK combined with (25 cm x 7.5 cm) crop geometry. Similarly, yield parameters like number of umbel plant-1, number of umbellates umbel-1 and seed yield (1253.0 kg ha-1) were also maximum with the same treatment. |
