To Assess the Effect of Different Sowing Time on the Performance of Different Local Aromatic Rice (Oryza sativa L.) Cultivars of Manipur

During the 2020-21 kharif season, a field experiment was carried out at the Agronomy department's research farm at the College of Agriculture, Central Agricultural University, Imphal, Manipur. With 12 treatments and 3 replications, it was carried out using a factorial randomized block design. The experiment comprised of different planting dates (6th July, 21st July, 5th August and 20th August) and three cultivars of black rice aromatic rice (Chakhao Poireiton, Makrei Kazik and Tangkhul Makrei/Khangamu). With a grain yield of 1475.24 kg/ha, Chakhao Poireiton produced the highest growth parameters, and Tangkhul Makrei/Khangamu produced the lowest growth parameters with a grain yield of 1384.53 kg/ha. Dates of sowing had significant impact on growth. Early planting (6th July) resulted in the highest growth parameters and grain yield (1508.07 kg/ha), while late planting (20th August) resulted in the lowest growth parameters and grain yield (1361.58 kg/ha). Thus, the cultivar Chakhao Poireiton of black rice sown on July 6th was suitable for improved growth and grain yield.
