EFFECT OF AGE OF SEEDLINGS AND NUMBER OF SEEDLINGS PER HILL ON GROWTH AND YIELD OF MANIPUR BLACK SCENTED RICE (Oryza sativa L.) CULTIVAR CHAKHAO POIREITON
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 25
Abstract
Field experiment was conducted during Kharif, 2015 at Agronomy research farm, COA, CAU, Imphal. The soil of experimental field was clay, acidic in reaction (pH 5.6), high in organic carbon (1.19), available potash (313kg/ha) and medium in available nitrogen (440kg/ha), available phosphorous (17kg/ha). The experiment was carried out with 4 levels of age (A) of seedlings (A15, A25, A35 and A45 day’s old seedlings) and 4 levels of number of seedlings/hill (S1, S2, S3 and S4 seedlings/hill). The different levels of age of seedling and number of seedling/hill has influenced significantly on growth parameters, and yield contributing characters as well as grain yield. The maximum number of effective tillers/hill (12.33) was obtained from the treatment A1S4. The maximum grain yield (2333kg/ha) was recorded in the treatment transplanted 15 days old seedling and 2 seedlings/hill. The higher grain yield was recorded in young seedling due to early establishment of seedling and efficient in nutrient uptake as well as the availability of suitable growing conditions in the early stage too. From the economic point of view, the highest gross return (Rs 1,08,945/ha), net return (Rs 69,536/ha) and Cost: Benefit ratio (1.76) were recorded from the treatment A1S2 (transplanting of 15 days old and 2 seedlings/hill).
