Aim: Plant nutrient
management through application of sulphur in combination with boron is
essential practice to sustain economic and quality yield in potato. The
present investigation was performed to determine the economic performance of
potato cultivation against integration of sulphur and boron with high grade
field was supplied with recommended dose of N, P and K (120:80:100 kg N, P2O5
and K2O per ha-1). Sulphur (wettable sulphur) and boron
(borovin) were applied as both, basal dose and foliar spray at 30 and 60 DAS
(days after sowing). Intercultural practices were carried out as per
recommendation and observations were recorded on chlorophyll content, yield
and economic attributes. Duncan's New Multiple Range Test was applied for
statistical analysis of observations.
application of sulphur or boron was reported to have significant effect on
dry matter and starch level in potato tubers, however highest dry matter
(26.31%) and starch (71.37%) content was recorded in T9 (2 foliar
sprays of 0.5% borovin and 0.25% sulphur). This was further reported with
highest economic yield (360 q ha-1), gross income (Rs. 2, 88,
000), net income (Rs. 2, 14, 900) and B:C ratio (2.940:1), followed by T3;
T5; T8 and T6.
and boron application has been reported to bring significant influence on the
chlorophyll level of potato plants consequently photosynthetic activity was
also influenced. The improved photosynthetic activity had increased the fresh
weight of potato tubers, dry matter and starch content of potato tubers when
sulphur was applied as foliar application in combination with boron or alone.
The tuber yield and B:C ratio was also observed to be significantly increased
due to foliar application of sulphur alone or in combination with boron.
