ASSESSING THE INTEGRATED EFFECT OF ORGANIC MANURE AND MINERAL FERTILIZERS ON CARROT GROWTH AND YIELD

Abstract

An experiment was conducted at the Research Farm, Arid Zone Research Center, DI Khan, to appraise the response of poultry manure, an organic manure, in amalgamation with mineral fertilizers on the development, produce, and quality of carrot. The highest gross yield (29.70 t ha⁻¹) of carrot was attained from the T7 treatment [recommended dose of mineral fertilizers (RDIF) +  poultry manure (RDP)], while the subsequent lowest gross yield (16.04 t ha⁻¹) was documented in the poultry manure treated plots (RDP). T7 treated carrot plants exhibited the uppermost values for root fresh weight (64.08 g), vendible yield (16.27 t ha⁻¹), length of shoot (76.01 cm), root diameter (11.48 mm), and N content (2.56%). Bearing in mind the major nutrients and biochemical physiognomies of carrot, the findings suggest that poultry manure is not adequate to maximize yield, but it positively impact when applied in combination with mineral fertilizers. The study also discovered that poultry manure had no noteworthy contribution to increasing N, P, K, and S content in soils.
