Abstract:

Aim of the present study was to check the impact of Melia azedarach dry fruit extract, farmyard manure and nitrogenous fertilizer application against cabbage aphid Brevicornye brassicae. B. brassicae is one of the key pests affect the quality and market value of cabbage. The home garden experiment was conducted in two season (September to December 2009 and February to May 2010). For this experiment totally five plots were prepared with 4 m length and 0.6 m width. Among the five plots one was used as control and another four was experimental plot for the application of nutrient and botanical spraying. M. azedarach dry fruit extract (5%) was mixed with 0.2% local soap solution and sprayed in experimental plot. Purposive sampling method was adopted for data collection for which the number of aphids was recorded from three leaves of each plant. The experimental results indicates that except farmyard manure and combination of farmyard manure+urea treated plot remaining all showed significant difference (p<0.025) in aphid population compared to control. The weight of the cabbage head did not show any significant difference (p>0.025) in control and farmyard manure treated plot but the remaining showed statistically significant difference. The experimental results for both cropping seasons were consistent. Nitrogenous fertilizer applications influence the growth of the plants but did not show any remarkable changes in cabbage head weight except plant growth. The study concludes that foliar and basal application of M. azedarach dry fruit powder had significant impact on cabbage aphid, B. brassicae. It can be a suitable alternative method to protect cabbage crop against aphid infestation particularly small farming community those who are unable to afford cost of chemical pesticides.
