Abstract:The experiment consisted of two factors, date of sowing (Factor A), crop geometry (Factor B) which were replicated three times under factorial randomized design to see the outcome their interactive effect on yield attributes of Chia. Experimental station of Agricultural University, Jodhpur basically known as Agriculture Research Station, Mandor was the designated place for execution of experiment in 2016-17 year. Different dates of sowing are 25th October (D1), 05th November (D2), 15th November (D3) and 25th November (D4) which come under factor A while as the crop spacing viz., 30 cm x 30 cm (P1), 45 cm x 30 cm (P2), 60 cm x 45 cm (P3) and 90 cm x 45 cm (P4) falls under factor b i.e. plant geometry. Observations on biological yield revealed that interaction between D1 x P1 recorded significantly higher biological yield (21169.98 kg ha-1) per hectare than rest of the interactions. Consequently, data on seed and husk yield per hectare revealed that interaction between D1 x P2 recorded significantly higher seed yield (685.44 kg ha-1) and husk yield (272.79 kg ha-1) per hectare than rest of the interactions except D1x P1 (658.15 kg ha-1 & 262.10 kg ha-1) respectively.
