Effect of Irrigation Regimes on Biochemical Studies of Red Cabbage (Brassica oleracea L. var. capitata f. rubra) under Mulch and Non-mulch Condition

Abstract

A field experiment was conducted at College of Horticulture and Forestry, Central Agriculture University, Pasighat, Arunachal Pradesh during 2019-20 to assess the “Effect of Irrigation Regimes on Biochemical Studies of Red Cabbage (Brassica oleracea L. var. capitata f. rubra) under Mulch and Non-mulch Condition”. The experiment was done in a randomized block design (RBD) with seven treatments and three replications as control, 100% CPE with drip irrigation, 80% CPE with drip irrigation, 60% CPE with drip irrigation, 100% CPE with drip irrigation under mulch, 80% CPE with drip irrigation under mulch, 60% CPE with drip irrigation under mulch. From the present investigation, it was observed that biochemical parameters like TSS (6.75 °B), total carbohydrates (3.30 g/100g) and anthocyanin (23.66 mg/100g) were maximum at control. While total protein content (2.84 g/100g) and ascorbic acid (102 mg/100g) were recorded higher in 60% CPE with drip irrigation. The findings demonstrated that using irrigation water at a lower rate than full drip irrigation rate can assist increase in TSS, total carbohydrate, anthocyanin, total protein and ascorbic acid concentrations in red cabbage.
