Abstract: Hydropriming is a promising cost effective strategy that aids farmers to attain a better yield by sorting out the challenges of poor stand establishment. An experiment was conducted at Coconut Research Station, Balaramapuram, Thiruvananthapuram, Kerala during kharif 2018 in a Randomised Block Design with ten treatments in three replications. The objective of the study was to find out the most cost-effective crop establishment technique for upland rice and to assess its impact on growth and yield of rice. The treatments comprised of line sowing dry and hydroprimed seeds @ 60 kg ha-1, broadcasting dry, hydroprimed and pre-germinated seeds @ 80 and 100 kg ha-1 and thomba method of planting at two different spacing (15× 10 cm and 20 × 10 cm). Broadcasting hydroprimed seeds at 80 kg ha-1recorded significantly maximum number of tillers (562.33) at harvest and registered high values for the yield attributes; the highest grain yield ha-1and B:C ratio. The study revealed that broadcasting hydroprimed seeds @ 80 kg ha-1 with a grain yield of 3900.7 kg ha-1 and B: C ratio of 1.72 is the cost-effective crop establishment technique for upland kharif rice in coconut garden.
