EFFECT OF MANURE AND MICRONUTRIENTS (BORON AND ZINC) ON GROWTH AND YIELD OF POTATO

Abstract

To study the effect of manure, zinc and boron on growth and yield of potato, an experiment was conducted in the farm under the Department of Soil Science, Sher-e-Bangla Agricultural University, Dhaka, during the period from November 2018 to February, 2019. The experiment was laid out into Randomized Complete Block Design (RCBD) with three replications. Single factor was comprised with the study viz. T 1 ii (100 kg N ha -1 + 35 kg P ha + 100 kgK ha -1 + 20 kgS ha -1 ), T 2 (T 1 + 4 t CD ha -1 ), T 3 (T 1 + 3 t PM ha + 5 kg Zn ha -1 ), T 5 (T 1 + 5 kg Zn ha -1 + 2 kg B ha -1 ), T 6 (T 1 + 4 t CD ha + 5 kg Zn ha -1 + 2 kg B ha -1 ) and T 7 (T 1 + 3 t PM ha -1 + 5 kg Zn ha -1 -1 ), T 4 -1 + 2 kg B ha ). Data were recorded on different growth, yield contributing parameters, yield of potato and nutrient content in soil. Most of the parameters showed significant difference among the treatment. Result revealed that most of the parameters showed best results with the treatment T 6 (T 1 + 4 t CD ha -1 -1 -1 + 5 kg Zn ha + 2 kg B ha -1 ) regarding growth and yield parameters and also nutrient content in soil and this treatment showed highest dry weight of haulm hill -1 (38.26 g), dry weight of 100 g fresh tuber (20.32 g), number of tuber hill -1 (8.12), tuber weight hill -1 (308.20 g), tuber yield ha -1 (26.42 t) and stover yield ha (20.44 t) whereas T 1 (100 kg N ha -1 + 35 kg P ha -1 + 100 K kg ha -1 -1 (T 1 -1 + 20 S kg ha ) showed lowest results regarding these parameters. So, it can be accomplished that the treatment T 6 (T 1 + 4 t CD ha -1 + 5 kg Zn ha -1 + 2 kg B ha ) can be treated as the best compared to others.
