An experiment was conducted on sandy loam soil to study the effect of time of sowing and crop geometry on yield
attributes, seed yield and the economics of Indian mustard (Brassica juncea L) cultivar RH-749 under irrigated condition
of Rajasthan. Results revealed that crop sown on October 24 recorded higher crop yield attributes including number of
branches/plant, siliquae/plant, seeds/siliqua, seeds weight/plant, test weight, seed yield (2159 kg/ha) and economics
with gross return (79898.64 Rs./ha), net return (54429.38 Rs./ha) and B:C ratio (3.14), respectively. The better plant
growth and higher dry matter accumulation in yield components was also observed as compared to other date of sowing.
Crop geometry of 45 x 30 cm recorded significantly increased branches/plant and seeds weight/plant (g) as compared to
all other crop geometry while number of siliquae/plant and test weight increased significantly as compared to all other
crop geometry except 45 x 15 cm crop geometry. Seed yield (2218 kg/ha), gross return (82085.61 Rs./ha), net return
(56496.35Rs./ha) and B:C ratio (3.21) were increased significantly in crop geometry of 30 x 20 cm over to 30 x 10 cm and
45 x 30 cm crop geometry. Hence, the present study suggested to revise plant to plant spacing with similar line to lines
spacing alongwith sowing in mid October could enhance the productivity of Indian mustard.
