Effect of waste water irrigation on the crop growth and fungal disease intensity on fennel (Foeniculum vulgare Mill.) in district Bareilly, Uttar Pradesh, India
Abstract
During the investigation it was observed that waste water regularly (WWR) used for irrigation of crop show adverse effect on plants growth and yield, thus significantly increased the disease intensity as compared to occasionally used waste water (WWO) and ground water (GW). WWR suppressed the growth of fennel plant and showed highest increase in disease intensity but the yield of crop was decreased gradually. The highest disease intensity was observed in Fusarium wilt disease caused by Fusarium sp. followed by stem gall. WWO showed the moderate (++) plant growth in comparison to normal growth of plants irrigated with GW and suppressed growth of crop irrigated by WWR. The WWO increased the total yield of crop followed by GW and showed the slightly decreased disease intensity except Fusarium wilt due to their composition of minerals which is necessary for plant growth. The study reveals that the high quantity of inorganic minerals was presented in WW followed by soil and GW respectively. The regular irrigation of crop by WWR showed the high accumulation of soil toxins and inorganic minerals in the field caused high disease intensity and poor growth yield of fennel crop as compared to irrigation by WWO and GW.
