Description |
The field experiment entitled “Effect of fertigation on yield, quality and fertilizer use efficiency in cabbage (Brassica oleracia var. Capitata).” was conducted at Water Technology Centre, College farm, College of Agriculture, Rajendranagar, Hyderabad during Rabi 2010-11. The experiment was laid out in a Randomized Block Design, consists of 10 treatments viz., Soil application of recommended dose of N,P,K (T1), 125% RDF N & K through fertigation at daily interval (T2), at 3 days interval (T3), at weekly interval (T4), 100% RDF N & K through fertigation at daily interval (T5), at 3 days interval (T6), at weekly interval (T7), 75% RDF N & K through fertigation at daily interval (T8), at 3 days interval (T9), at weekly interval(T10) and replicated thrice. Recommended dose of phosphorus was applied as basal for all the treatments. The experimental soil is sandy clay loam, low in available nitrogen, medium in available phosphorus and potassium. Maximum dry matter production of 4793 kg ha-1 was recorded in cabbage with application of 125% RDF N & K through fertigation at daily interval which was statistically on par with 100% RDF N & K through fertigation at daily interval (4553 kg ha-1). The cabbage yield was observed to be higher under daily fertigation of N and K with 100% and 125% recommended dose with 16.92 and 15.53 t ha-1 respectively. Total nutrient uptake was highest (146.65 kg ha-1 N and 189.41 kg ha-1 K) with the application of 125% RDF of N and K through fertigation at daily interval. Fertigation has no significant effect on total phosphorus and sulphur uptake. The highest (100.50 kg kg-1) N and K (131.37 kg kg-1) fertilizer use efficiency was recorded with daily fertigation of 75% recommended dose of N and K and the highest water productivity (7.92 kg m-3) was recorded in daily fertigation with 100% RDF. Application of 125% recommended dose of N and K through fertigation at daily interval resulted in the highest head diameter (14.40 cm). The highest head weight (923 g) was resulted from application of 100% RDF through fertigation at daily interval. Significantly higher Total Soluble Salts content (4.66%) and ascorbic acid content (118.37 mg 100 g-1) was registered under daily fertigation of 125% RDF N & K. Daily fertigation with 100% N and K resulted in the highest gross return (Rs.84,635 ha-1) and net return (Rs.62,692 ha-1) and benefit cost ratio of 2.85.Hence it can be concluded that for achieving maximum yield and net profits, the cabbage crop can be given fertigation at daily interval with 100 per cent of recommended dose of fertilizers. |
