Abstract:
A field experiment was conducted at the Agricultural Research Farm of Pandit Deen Dayal Upadhyay Institute of Agricultural Sciences, Bishnupur, Utlou, Manipur to study the effect of planting date and spacing on growth and yield of black aromatic rice (Oryza sativa L.) cultivar chakhao poireiton. The results revealed that the growth attributes (plant height, number of tillers per hill and dry weight) were significantly enhanced by different planting date and spacing of black aromatic (chakhao poireiton). The interaction of early planting date i.e. (18 June, 2018) and higher planting space i.e. (20 cm x 25 cm) significantly increased the plant height and dry weight for all the growth stages. The individual effect of planting date, D1 (18 June, 2018) and spacing, S2 (20 cm x 25 cm) significantly increased the yield and yield attributes of black aromatic (chakhao poireiton). The treatment combination D1S2 (18 June, 2018 + 20 cm x 25 cm) gave the maximum number of effective tillers per hill i.e. 7.19 and number of seeds per panicle i.e. 92.53, grain yield (2063.66 kg/ha), stover yield (3872.41 kg/ha), biomass yield (5936.07 kg/ha) and harvest index (34.76%). The highest gross return (₹ 132863.50), net return (₹ 84492.42) and benefit-cost ratio (BCR) (2.74) was obtained from the treatment D1S2 (18 June, 2018) + 20 cm x 25 cm.
