ABSTRACT
Present investigation “Study on productivity of carrot under various sowing methods and
irrigation levels” was conducted on carrot var. Pusa Yamdagini in Department of Soil Science and
Water Management, Dr. Y S Parmar University and Horticulture and Forestry, Nauni, Solan (HP).
The study was focused on ascertaining the response of irrigation levels and sowing methods on
growth, yield, water requirement, water use efficiency, nutrient content and their uptake in carrot.
Eight treatment combinations comprising of four irrigation levels viz. 0.6 (I1), 0.8 (I2), 1.0 (I3) and 1.2
(I4) IW/CPE ratio and two sowing methods (S1: flat-bed and S2: ridge method) were replicated thrice
in Randomised Block Design (Factorial) with plot size 3m × 2m and spacing of 30 cm × 10 cm. The
irrigation level I4 and I3 recorded significantly higher soil moisture content, nutrient content, uptake
and growth of carrot over I1. Maximum carrot yield (323.44 q ha-1) was recorded under I4 followed by
I3 (305.52 q ha-1) and showed an increase of 77.78 (I4) per cent and 66.36 (I3) per cent over I1.
Irrigation level I3 exhibited highest WUE (179.13 kg ha-1 mm-1) with total water requirement of 23.74
cm followed by I2 irrigation level. There was 37.01 and 30.78 per cent increase in WUE under I3 and
I2 over I1, respectively. Treatment combinations S2I4, S2I3 and S1I4 increased the nutrient content in
soil and plant which significantly increased the growth and yield of carrot. Treatment combination
S2I4 was found to be most economical and revealed highest B:C ratio (2.96:1) followed by S2I3
(2.81:1). On the basis of B:C ratio, research findings revealed that ridge method of sowing with 1.2
IW/CPE irrigation level showed better results in terms of growth and yield of carrot.
