 ABSTRACT

Field experiment was conducted at Research Farm of Jawaharlal Nehru Krishi Vishwa Vidyalaya, College of Agriculture, Tikamgarh (Madhya Pradesh), India during rabi season of 2015-16 to study the effect of sowing dates and planting geometry on growth, yield attributes and yield of Indian mustard var. RGN-73. The experiment was carried out in split plot design with 3 sowing dates viz., 20 October, 2015, 30 October, 2015 and 09 November, 2015, and 5 planting geometry viz., 45 cm x 30 cm, 45cm x 15 cm, 30 cm x 30 cm, 30 cm x 20 cm and 30 cm x 10 cm as main plot and sub-plot treatments, respectively. Among different sowing dates, crop sown on October 20 resulted into significantly greater plant height (cm), more number of branches(plant-1), higher leaf area index and higher total plant dry biomass (g plant-1) followed October 30 and November 09 sown crops. Similarly number of siliquae (plant-1), 1000-seed weight (g), seed yield (kg ha-1), stover yield (kg ha-1), biological yield (kg ha-) and harvest index were also significantly higher under October 20 followed by October 30 and November 09 sown crops. Consecutive 10 days deley in sowing from October 20 to October 30 and November 09 caused a loss in seed yield by 27.8 % and 40.7%., respectively. Among different planting geometries ,45cm x 30cm showed significantly more number of branches (plant-1) higher leaf area index and more total dry biomass (g plant-1) and the lowest with 30cm x 10cm.However, significantly greater plant height (cm) was recorded with planting geometry of 30cm x 10cm. Similarly, number of siliquae plant (plant-1), number of seeds (siliqua-1) and 1000 –seed weight (g) were also observed higher with 45cm x 30cm. However, seed yield (kg ha-1), biological yield (kg ha-1) and harvest index were recorded significantly higher with 30cm x 10cm as compared to other planting geometries.

Key words: Planting geometries, Harvest index, Rapeseed-mustard
