Response of Carrot ( Daucus carota L.) Growth and Yields to Organic Manure and Inorganic Fertilizers

摘要

Pot experiments were conducted to observe the effect of different organic manures and NPK fertilizerson growth and yield of carrot at Faculty of Agriculture, Gomal University, D. I. Khan, during 2011-12 and 2012-13. These experiments were laid out in complete randomized design (CRD) with seven treatments and eachtreatment was replicated five times. The treatments under study were control, FYM @ 30 t ha 1, poultry manure@ 10 t ha 1, goat manure @ 15 t ha 1, pressmud @ 20 t ha 1, sewage sludge @ 20 t ha 1 and NPK @ 100-100-125 kg ha 1. Data on leaves plant 1, leaf length (cm), leaves weight plant 1, root length (cm), root diameter (cm),root weight plant 1, biomass weight plant 1 and root yield (t ha 1) were taken and analyzed statistically.The results revealed that all growth and yield parameters were significantly improved by applying organicmanures and NPK. The highest values for all attributes were recorded in NPK treated plants as it producedmaximum leaves plant 1 (6.87 & 6.07), leaf length (29.47 & 30.17 cm), leaves weight plant 1 (15.00 & 14.67 g),root length (18.47 & 17.60 cm), root diameter (2.37 & 2.10 cm), root weight plant 1(99.33 & 114.33 g), biomassweight plant 1 ( 114.33 & 129.33 g) and root yield (34.73 & 40.73 t ha 1) during both years, respectively.Amongst the manures, poultry manure (PM) and goat manure (GM) showed far more better results for carrotgrowth and yield parameters, followed by sewage sludge (SS) and pressmud (PrM) and FYM, respectively.
