Abstract
The present investigation entitled “Management of tuber cracking in potato
(Solanum tuberosum L.) cv. Kufri Chipsona-3 through boron application” was
conducted in the Research Farm of AICRP on potato, Bhubanewar during rabi, 2017-18.
The experiment comprised of five treatments, such as- T 1 = Recommended dose of fertilizers
(RDF) of NPK; T 2 = RDF of NPK + 2.0 kg Boron /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. The treatments
were arranged in a completely randomized block design replicated for four times. Observations
were taken on plant growth parameters and tuber yield at specified days after planting. Samples
of soil, shoot and tubers were analyzed under different treatments. Our study shows that
application of recommended dose of nitrogen, phosphorus and potassic fertilizers along
with 0.1 % Boron application three times at 40, 50 and 60 days after planting resulted in
lowest tuber cracking although Boron application did not significantly increase the overall
tuber yield. Number of Cracked tubers showed a significant relation with the treatments of
Boron. The foliar spray of Boron application was more effective than soil application of
Boron which might be due to continuous availability of nutrients during tuber bulking
phases. Three times foliar application (at 40,50 and 60 days) of Boron was found to be superior
than other foliar treatments because of comparatively better quality non cracked tubers,
which resulted in maximum net return and B:C ratio (1.27).
