Effect of Different Date of Planting and Various Mulching Practices on Growth, Yield Attributes and Yield of Potato

Abstract

The present research work was conducted at Pili kothi farm, Department of Agronomy, Tilak Dhari Post Graduate College, Jaunpur, Uttar Pradesh during winter season of 2018 and 2019. The experiment was laid out in Factorial Randomized Block Design. The treatments comprised of different planting dates viz. 20 days early planting on 17th October, 10 days early planting on 27th October, Optimum planting time on 7th November, 10 days late planting on 17th November and 20 days late planting on 27th November and different mulching practices viz. Organic mulch (Paddy straw at 5 t/ha), Plastic mulch (Black colour) and Control (Without mulch) of potato. There were 15 treatments and each were replicated to four folds. These treatments were randomly arranged in each replication and divided into sixty plots. The results revealed that the significantly maximum emergence percentage 30 Days after planting (92.70, 94.30 and 93.50), Plant height (cm) at 45 DAP (40.40 cm, 42.20 cm and 41.30 cm), Numbers of compound leaves/hill at 45 DAP (57.10, 57.40 and 57.30), Number of tubers/plot (603.80, 640.00 and 621.90), Weight of tubers/plot (kg) (37.20, 37.80 and 37.50) and Number of tubers/plant (10.10, 10.70 and 10.40) were recorded under 20 Days Early Planting On 17th October among different planting dates during first, second and mean data also. Whereas among the mulching practices significant variation were recorded among the all parameter except number of compound leaves. However maximum emergence percentage 30 DAP (90.20, 91.60 and 90.90), Plant height (cm) at 45 DAP (35.70 cm, 37.50 cm and 36.60 cm), Numbers of compound leaves/hill at 45 DAP (53.70, 54.20 and 53.90), Number of tubers/plot (513.00, 552.80 and 532.90), Weight of tubers/plot (kg) (34.10, 34.60 and 34.30) and Number of tubers/plant (8.60, 9.20 and 8.90) under the organic mulch (paddy straw at 5 t/ha) respectively, during first, second as well as in mean data also.
