INFLUENCE OF CLYBIO AND ECOAGRA CONCENTRATION ON GROWTH AND YIELD OF POTATO (Solanum tuberosum cv. Lalpakri)

Abstract

A field experiment was conducted at the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka during the period from November 2019 to February 2020 to evaluate the influence of clybio and ecoagra concentrations on growth and yield of lalpakri. The experiment was consisted of nine treatments namely T 0 : Untreated (control); C 1 : Clybio @ 1.0 ml/L; C : Clybio @ 2.0 ml/L; E 1 : Ecoagra @ 1.0 ml/L; E 2 : Ecoagra @ 2.0 ml/L; C : Clybio @ 1.0 ml/L + Ecoagra @ 1.0 ml/L; C 1 +E : Clybio @ 1.0 ml/L + Ecoagra @ 2.0 ml/L; C 2 +E 1 2 : Clybio @ 2.0 ml/L + Ecoagra @ 1.0 ml/L; C : Clybio @ 2.0 ml/L + Ecoagra @ 2.0 ml/L. All the treatments were applied to the soil of potato field along with leaves of potato plants. The single factorial experiments were laid out in Randomized Complete Block Design with three replications. Among the treatments maximum number of tuber (15.3/hill), tuber length (46.8 mm), tuber diameter (45.7 mm), individual tuber weight (29.4 g), yield (451.0 g/hill), yield (30.07 t/ha) was found in the case of C treatment. On the other hand minimum number of tuber (11.3/hill), tuber length (31.2 mm), tuber diameter (31.0 mm), individual tuber weight (12.4g), yield (138.7 g/hill), yield (9.2 t/ha), was found from T treatment. In view of overall performances, C 2 +E 2 0 treatment that implies Clybio @ 2.0 ml/L + Ecoagra @ 2.0 ml/L provided the best result for growth and yield attributes.
