tailieunhanh - Role of pinching on floral and yield parameters in African marigold (Tagetes erecta L.) cv. local selection
Field experiment was conducted during 2004-05 and 2005-06 at CCS Haryana Agricultural University, Hisar to study the optimum time of pinching for better flower production in African marigold cv. Local selection. There were six levels of pinchings . No pinching, 7 DAT (days after transplanting), 14 DAT, 21 DAT, 28 DAT and 35 DAT). A uniform dose of nitrogen @ 20 g/m2 , phosphorus @ 10 g/m2, potassium @ 10 g/m2 and 10 kg FYM per plot ( m x m) was applied. For statistical analysis factorial randomized block design was used with three replications. Pinching at 28 DAT significantly improved the days to bud initiation, number of buds per plant, days to flowering, duration of flowering, stalk length. The maximum flower weight, dry flower weight, number of flowers per plant, flower yield per plant and flower yield per hectare was obtained at 28 DAT. | Role of pinching on floral and yield parameters in African marigold (Tagetes erecta L.) cv. local selection
