Abstract:
A pot experiment was carried out to check the impact of different organic manures and inorganic fertilizers on the growth and yield of turnip, at Horticulture Departmental experimental area, Faculty of Agriculture, Gomal University, D.I. Khan, during 2012-13. The experiment was laid out in RCD with seven treatments replicated three times. Treatments contained control (no fertilizer added), FYM @ 25 t/hec, Poultry manure @ 10 t/hec, Goat manure @ 15 t/hec, Press mud @ 20 t/hec, Sewage sludge @ 20 t/hec and NPK @ 120-65-100 kg/hec. Data on leaves per plant, leaf length (cm), fresh leaf weight per plant (g), dry leaf weight per plant (g), root length (cm), root diameter (cm), fresh root weight per plant (g), dry root weight per plant (g), total biomass per plant (g), root yield per pot (g) and root yield (ton per ha) was recorded and analyzed statistically. The results revealed that all growth and yield parameters were significantly enhanced by the application of organic manures and NPK. Maximum values were recorded in NPK treated plants, as compared to all the treatments under studied, by producing 13.22 leaves per plant, 29.90 cm long leaf, fresh leaf weight per plant (52.83 g),
dry leaf weight per plant (11.15 g), root length (7.07 cm), root diameter (7.23 cm), fresh root weight
per plant (241.20 g), dry root weight per plant (22.25 g), total biomass per plant (313.37 g), root yield
per pot (382.40 g) and 382.40 root yield (382.40 ton per hectare). It was also confirmed that poultry
manure exhibited superiority as compared to other organic manures
