Abstract:
An experiment entitled, “Effects of planting methods on growth and yield of paddy (Oryza sativa L.)” was carried out during Kharif, 2020 at Agricultural Research Station Farm, VadgaonMaval, Tal. Maval, Dist. Pune to investigate effects of planting methods on growth attributes and yield of paddy (Oryza sativa L.). The field experiment was laid out in Randomized Block Design (RBD) with three replications. There were eight treatments comprising of different sowing methods of rice viz., T₁-Sowing as direct seeded rice (DSR) at 22.5cm by bullock drawn seed drill, T₂-Sowing as direct seeded rice (DSR) at 30cm by bullock drawn seed drill, T₃-Sowing by dibbling method at 20 x 15 cm², T₄-Direct sowing of rice by tractor operated mechanical seed drill, T₅-Direct sowing of rice by ‘Saguna Rice Technique’(SRT), T₆-Direct sowing of rice by ‘Modified Direct Seeded Rice Technique’(MDSRT), T₇-University recommended method (Four Point Agro-Technology or Char Sutri Method) and T₈-Farmer’s practice-Conventional transplanting method. The periodical observations on growth attributes and yield were recorded to assess the treatment effects. Results revealed that planting methods had significant effects on growth attributes and yield of paddy. The treatment T₆-Direct sowing of rice by ‘Modified Direct Seeded Rice Technique’ (MDSRT) recorded the maximum height at 14 DAS (22.2 cm), 28 DAS (39.9 cm), 42 DAS (59.9 cm), 56 DAS (69.7 cm), 70 DAS (82.5 cm), 84 DAS (90.0 cm) and at harvest (94.5 cm). Number of tillers m^-2 were significantly more with T₆-Direct sowing of rice by ‘Modified Direct Seeded Rice Technique’ (MDSRT) than rest of all the planting methods at all growth stages as 42 DAS (127.3), 56 DAS (157.2), 70 DAS (196.5), 84 DAS (218.3) and at harvest (229.8). The grain yield (63.74 q ha^-1) and straw yield (68.88 q ha^-1) were significantly superior in the treatment T₆-Direct sowing of rice by ‘Modified Direct Seeded Rice Technique’ (MDSRT) (63.74 q ha^-1) than rest of the sowing methods except it was at par with the treatment T₇-University recommended method (Four Point Agro-technology) having grain yield(55.60 q ha^-1) and straw yield of paddy (60.10 q ha^-1) respectively.
