Assessment of growth, yield, tuber quality and profitability of potato upon boron fertilization

Abstract

Aim : Methodology :Results : Interpretation :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.A field 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 , Recommended dose of fertilizer (RDF) of NPK; T , RDF of NPK + 2.0 kg soil applied B/ha; T , RDF of NPK + 0.1% boric acid spray at 40 days after planting (DAP); T , RDF of NPK + 0.1% boric acid spray at 40 and 60 DAP; and T , 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.Experimental findings showed that RDF of NPK + 0.1% boric acid spray (thrice) produced significantly higher number (3.70 × 10 ha ) and yield (33.49 t ha ) 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.

Effect of Urea and Nano-Nitrogen Fertigation and Foliar Application of Nano-Boron and Molybdenum on some Growth and Yield Parameters of Potato

“…It is clear from these results table (3) that there is a direct relationship occurs between the yield of soft tubers and ascorbic products. These results are consistent with those obtained by [54,59] revealed in their study that the recommended application of NPK and boric acid increased by (0.1) % significantly increased vitamin C (ascorbic acid). The application of molybdenum promoted the growth of vegetable crops and also improved traits such as ascorbic acid [60].…”

“…El-Dissoky and Abdel-Kadar (2013) observed the effect of boron foliar application on some potato varieties under sedimentary soil conditions. The boron levels (0, 30, 60 and 90) mg/L -1 showed that foliar application of B significantly affected specific tubular parameters, including [54] in their experience clarify that the recommended application of NPK and boric acid significantly increased protein in potato tubers by (0.1) %.…”

Integrated Application of Micronutrients to Improve Growth, Yield, Quality and Economic Yield in Potato - A Review

“…Among all treatments, 180 kg/ha Nitrogen and 50 kg/ha Sulphur showed highest net income and benefit cost ratio. Sarkar et al, (2018) in their experiment revealed that recommended doses of NPK and 0.1% boric acid significantly increases specific gravity, tuber hardness, total soluble solids, total acidity, Vitamin C, protein, and starch content with lowest phenol content. So it is best treatment for producing the processing grade potato.…”

“…It significantly improved tuber yield, dry matter content, starch content, economic yield and net income. Sarkar et al, (2018) in their experiment revealed that application of boron significantly increased quality characters, namely, specific gravity, TSS, tuber hardness, total acidity and vitamin C content. The lowest phenol content is good for chip colour and it is good for processing industry (Bandana et al, 2016).…”

“…Produced significantly higher number and yield of tuber of processing grade Sarkar et al, (2018) Low reducing sugar is preferred for processing. El babky et al, (2010) reported that Quality characters namely, total sugar, total carbohydrate and crude protein increases by application of Zn.…”
