摘要
Aim : The study aimed to investigate the effect of soil and foliar boron fertilization on the growth, productivity and quality well as benefit in processing grade potato (Kufri Chipsona-3) in alluvial soil at West Bengal, India.
Methodology : Afield experiment was carried out on alluvial soil at West Bengal during the winter season of 2014-15 and 2015-16. The experiment comprised of five treatments [T-1, Recommended dose of fertilizer (RDF) of NPK; T-2, RDF of NPK + 2.0 kg soil applied B/ha; T-3, RDF of NPK + 0.1% boric acid spray at 40 days after planting (DAP); T-4, RDF of NPK + 0.1% boric acid spray at 40 and 60 DAP; and T-5, RDF of NPK + 0.1% boric acid spray at 40, 50 and 60 DAP] arranged in a completely randomized block design replicated four times. Plant growth, yield, nutrient concentration and quality parameters of potato tuber (specific gravity, total soluble solids, tuber hardness, total acidity, Vitamin C and protein) were analyzed in the experiment.
Results : Experimental findings showed that RDF of NPK + 0.1% boric acid spray (thrice) produced significantly higher number (3.70 x 10(6) ha(-1)) and yield (33.49 t ha(-1)) of processing grade tuber than other boron levels (foliar and soil) tested. Application of RDF of NPK + 0.1% boric acid spray (thrice) exhibited its superiority by producing tubers with significantly higher specific gravity, total soluble solids, tuber hardness, total acidity, Vitamin C, protein and starch content with lowest phenol content and lighter chip colour.
Interpretation : The results of this study indicate that application of boron (0.1% boric acid at 40, 50 and 60 DAP) in combination with RDF (200 kg N, 150 K2O and 150 kg P2O5 ha(-1)) is required for optimum yield of processing grade potato(cv. Kufri Chipsona-3) in alluvial Gangetic plains of West Bengal.
