| dc.description.abstract | A field experiment entitled “Effect of tillage and irrigation levels on growth and yield of Indian mustard (Brassica juncea L.)” was carried out during rabi season of 2014-15 at Agricultural Research Farm of Tirhut College of Agriculture, Dholi, (Muzaffarpur), a campus of Rajendra Agricultural University, Pusa (Samastipur), Bihar, (India). The treatments comprised three tillage practices [zero tillage (T1), reduced tillage (T2) and conventional tillage (T3)] in main plots and four irrigation levels [No irrigation (I1), One irrigation (I2) at 35 DAS, Two irrigations (I3) at 35 and 60 DAS and Three irrigations (I4) at 35, 60 and 90 DAS] in sub-plots. The treatments were replicated thrice in split plot design. The soil of the experimental plot was sandy loam in texture, alkaline in reaction (pH -8.51), low in organic carbon & available N, P2O5, K2O and S in medium range. The Indian mustard variety ‘Rajendra Sufalam’ was sown at a distance of 30 × 15 cm using the seed rate of 5 kg/ha with recommended fertilizer doses. Among the tillage practices, conventional tillage proved significantly superior in all growth parameters (plant height, crop growth rate, leaf area index and number of primary & secondary branches), yield attributes and yield. The conventional tillage significantly improved the grain yield of mustard over zero tillage by 18.08 % and was found statistically at par with reduced tillage. Irrigation levels, also significantly influenced all growth parameters (plant height, crop growth rate, leaf area index and number of primary & secondary branches), yield and yield attributing parameters. Three irrigation levels had ability to significantly enhanced the grain yield by 46.48 % over no irrigation under sandy loam condition. Increment in grain yield of mustard under conventional tillage resulted in maximum gross return ( 63712/ha) and net return ( 41403/ha) as compared to other treatments. On the basis of economics of mustard under irrigation levels, it was found that highest gross return ( 69070/ha), net return ( 46994/ha) and B: C ratio (2.12) was incurred with application of three levels of irrigation. | en_US |
