Growth and development of maize (Zea mays L.) in response to different moisture conservation and integrated nutrient management practices under rainfed condition

Author(s): Binoy Chhetri and AC Sinha
Abstract: A study was carried out to investigate the effect of moisture conservation practices and integrated nutrient management of growth and yield on maize (Zea mays L.) during pre kharif seasons of 2013 and 2014 at the Instructional Farm of Uttar Banga Krishi Viswavidyalaya, Cooch Behar, West Bengal.The result showed that the moisture conservation practices revealed that, the highest plant height (215.7 & 219.6 cm at harvest), leaf area index (LAI) (4.39 & 4.42 at 75 days after sowing), dry matter accumulation (DMA) (1198.1 & 1207.6 g m-2 at harvest), crop growth rate (CGR) (19.60 & 20.74 g. g m-2 at 61-75 days after sowing), grain yield (4014 & 4694 kg/ha), stover yield (11942 & 12184 kg/ha), harvest index (25.07 & 27.81%), nitrogen, phosphorus and potassium uptake (87.27 & 92.65, 52.72 & 55.91 and 102.03 & 106.23 kg/ha) and yield attributing characters was recorded under irrigation (M1) as compared to other treatments. Among the integrated nutrient management, the highest plant height (215.5 & 218.1cm at harvest), LAI (4.25 & 4.27 at 75 days after sowing), DMA (1162.2 & 1171.3 g m-2 at harvest), CGR (19.15 & 19.85 g. g m-2 at 61-75 days after sowing), grain yield (3907 & 4502 kg/ha), stover yield (11518 & 11705 kg/ha), harvest index (25.03 & 27.54%) and nitrogen, phosphorus and potassium uptake (88.78 & 91.82, 49.52 & 53.45 and 97.33 & 101.38 kg/ha) was recorded under 75% RDF + PSB + Azotobacter + vermicompost @ 5.0 t/ha (N3) as compared to other treatments. It may be concluded that maize grown with irrigation and supplied with 75% RDF + PSB + Azotobacter + vermicompost @ 5.0 t/ha (N3) is best for obtaining overall gain on a sustainable basis.
