IMPACT OF SEWAGE SLUDGE ON PEA (Pisum sativum) IN SALINE USAR SOIL
Indian journal of scientific research
Salinity in the arid and semi-arid regions is a serious threat to agriculture in the World. It is known one third of irrigated land is already affected by salinity and the level of is still rising. It is therefore, becomes very much important to explore the possibilities of overcoming this limitation in raising the good crops under the conditions of high salinity without much substantive decrease in the yield and the quality of grains. The present work was planned to study the effect of sewage
... e effect of sewage sludge application on growth and productivity of pea (Pisum sativum) in saline user land. Four different types of treatments i.e. untreated saline soil (T), saline soil: fertilizer (10:1, v/v; T1), saline soil: sludge (10:1, v/v; T2) and saline soil: sludge (2:1, v/v; T3) were used for the present study. The experiments were conduct in earthen pots (35 cm diameter). The pH, organic matter, EC, CEC, mineral elements and heavy metals were measured in soil and sludge. The seed germination, plant height, shoot and root dry weight, root to shoot ratio and various yield and biochemical parameters of pea plant were improved drastically in sludge treated soil. Improvements were observed in all the parameters in the sequence of saline soil< soil: fertilizer (10;1)<soil: sludge(10:1)< soil: sludge(2;1) and the maximum improvement occurred in the T3 treated pot.
