Description A study was carried out during 2005-07 to know the utility and effect of sugarcane
based industrial wastes on maize-chickpea cropping sequence in Vertisol.
A slight increase in pH, organic carbon and higher increase in EC was recorded in
distillery spentwash irrigated soils. Available nitrogen, phosphorus and micronutrient status
of spentwash irrigated profiles also increased slightly while, available potassium increased
substantially than normal water irrigation.
Available nitrogen release was higher in integrated treatments than organics alone at
initial stages of incubation while, it was reverse in later stages. Treatments involving
spentwash recorded higher release both in organic and integrated treatments.
Field experiments revealed that among the treatments, 50% RDN (urea) + 50% RDN
(BSW) was superior in terms of growth, yield, nitrogen and phosphorus uptake of maize. The
uptake of potassium and sodium was higher with application of 100% RDN (BSW).
The residual effect of 100% RDN (BSW) was superior in terms of growth and yield
of chickpea. The uptake of N, P, K and Na was highest in 100% RDN (BSW) and lowest in
100% RDN (urea). The 100% RDN through organics alone also recorded higher uptake of
nutrients than integrated treatments.
The EC values differed significantly but were less than 1 dSm-1. The available N, P, K
and S contents of soil also differed significantly. Treatments, 100% RDN (BSW) and 100%
RDN (urea) recorded highest and lowest nutrient status except P status which was highest in
100% RDN (BC).
The organic treatments resulted in higher micronutrient status in soil than the other
treatments. The dehydrogenase, phosphatase and urease activities in soil also showed
significant differences.
