Effect of spacing and spike maintenance for yield maximization in castor (Ricinus communis L.)


Author(s): G Senthil Kumar and SR Venkatachalam

Abstract: A field experiment was conducted at Tapioca and Castor Research Station, Yethapur, Salem district, Tamil Nadu during the year 2012-2014, to study the effect of spacing and spike maintenance for yield maximization in castor. This study was initiated with castor hybrid YRCH1 and the following treatments were imposed. In main plot, different spacing viz., 60 x 60 cm (M1), 90 x 60 cm (M2), 90 x 90 cm (M3), 120 x 90 cm (M4), 120 x 120 cm (M5). In sub plot, spike maintenance viz., maintaining primary spike alone (S1), maintaining secondary spike alone (S2), maintaining primary and secondary spikes alone (S3), allowing all the orders of spike (S4). The field trial was laid out in split plot design with three replications. The results revealed that, spacing of 120 x 120 cm along with allowing all the orders of spikes recorded higher seed yield which was on par with the spacing of 120 x 90 cm along with allowing all the orders of spikes.
