EFFECT OF PHOSPHOROUS AND BORON ON THE GROWTH AND YIELD OF POTATO

Abstract

The experiment was carried out at the research field, Sher-e-Bangla Agricultural University, Dhaka-1207, from November 2021 to February 2022 to study the effect of phosphorous and boron on the growth and yield of potato (Solanum tuberosum). Three levels of phosphorous (P 0 = 0 kg P ha ii

-1 , P 1 = 30 kg P ha -1 , P 2 = 40 kg P ha ) and three levels of boron (B 0 = 0 kg B ha -1 , B 1 = 2 kg B ha -1 , P 2 = 3 kg B ha -1 ) were used for this study. The experiment was carried out using RCBD with nine treatment combinations and three replications. The data on growth and yield parameters of potato were recorded. Most of the parameters were significantly affected by different levels of P application. Generally, P 2 gave the best results and showed the highest tuber yield (30.47 t ha -1 ), and marketable yield (26.63 t ha -1 ). Most of the parameters were also significantly affected by boron treatments. The highest yield (28.92 t ha -1 -1 ), and highest marketable yield (25.3 t ha ) resulted from B 2 treatment. Considering the combined effect of P and B the maximum plant height (50.70 cm), number of stems (6.17), number of leaves

hill -1 (109), number of tubers hill -1 (7.33), weight of tubers hill -1 (552.10 gm), weight of tubers plot -1 (13.57 kg), yield (33.99 t ha -1 ), marketable yield (29.54 t ha -1 ), tuber length (18.70 cm) and tuber width (16.13 cm) resulted from the P 2 B 2 treatment combination. On the other hand, the minimum plant height (38.10 cm), number of stems hill -1 (3.17), number of leaves hill (51.53), number of tubers hill -1 (4.38 kg), yield (10.97 t ha (4.17), weight of tubers hill -1 -1 -1 (181.33 gm), weight of tubers plot ), lowest marketable yield (6.18 t ha -1 ), tuber length (15cm), and tuber width (12.13 cm) were recorded from P 0 B 0 (control) treatment combination. So, considering the aforementioned findings, P 2 treatment (40 kg P ha -1 ) with B 2 treatment (3 kg B ha -1 ) performed the best results for the growth and yield of potato.
