Abstract
A field experiment entitled, “Effect of sewage water and sewage sludge on sorghum
(Sorghum bicolor L.)”, was conducted during kharif season at the KVK Sonipat of CCS Haryana
Agricultural University, Hisar (India). The soil of the experimental field was sandy loam in
texture; low in organic carbon, nitrogen; low in phosphorus; high in potassium and slightly
alkaline in reaction.
The field experiment was laid out in split plot design with three replications. The
treatments consisted of all irrigation with sewage water (4 irrigation), 3 irrigation with sewage
water + 1 irrigation with tube well water, 2 irrigation with sewage water + 2 irrigation with tube
well water, 1 irrigation with sewage water + 3 irrigation with tube well water and all irrigation
with tube well water in main plot treatments and sewage sludge @ 10 t ha-1, 50% sewage sludge
+ 50% recommended fertilizers and recommended fertilizer (80 kg N + 30 kg P2O5) in subplots.
The irrigation treatments where all irrigation with sewage water proved its
superiority over irrigation treatments with tube well water in respect of plant height, dry matter
accumulation. The nitrogen, phosphorus, potassium content and uptake was superior where all
irrigation with sewage water were applied Significantly the crop harvested higher fodder yield where all irrigation were applied
with sewage water. The pH of the soil decrease with the use of sewage water. EC, organic carbon
and micronutrient content of soil increased where all irrigation were applied with sewage water
compared to where all irrigation were applied with tube well water.
Growth parameters, viz., plant height, dry matter accumulation and fodder yield
of crop increased with the use of sewage sludge @ 10 t ha-1 over control where recommended
fertilizer were applied. The total N, P, K content and uptake, protein content were significantly
higher where we use sewage sludge @ 10 t ha-1 were applied compared to recommended
fertilizer
Based on the study it may be concluded that the application of sewage water and
sewage sludge harvested maximum plant height, dry matter accumulation, and fodder yield. The
protein content, organic carbon, N, P, and K increased significantly with the use of sewage water
and sewage sludge.
