CORRELATION STUDIES ON NEEM (Azadirachta indica A. Juss) WITH RESPECT TO FLOWER TO FRUIT CONVERSION by PRABAKARAN, P., KUMARAN, K., RADHAKRISHNAN, S. AND UMARANI, R. <p>In the present study, ten plus trees were selected based on morphologically superior parents at Forest College and Research Institute, Mettupalayam, for investigation of flowering phenology of Neem (<em>Azadirachta indica</em>). From the observation 100 fruit weight and oil percent had significant high heritability and genetic advance this may indicate additive gene action among the traits. Inflorescence length and 100 fruit weight had high positive correlation followed by number of fruits per inflorescence with fruiting percent. Therefore, those phonological traits are used as a selection index for future genetic improvement studies of neem for high seed production.</p> PRABAKARAN, P*., KUMARAN, K., RADHAKRISHNAN, S.

EFFECT OF DIFFERENT TREATMENT COMBINATION ON EGG LAYING OF SHOOT FLY, Atherigona soccata (RONDANI) IN MAIZE CROP (Zea mays L.) by AKSHAY KUMAR, R.S. SINGH, KRIPA SHANKAR, VIKRANT AND DEVENDRA SINGH <p>The field experiment was conducted in two consecutive year (Spring 2015 and 2016) at NawabGanj Farm of C. S. Azad University of Agriculture and Technology, Kanpur 208002 (U.P.). It is evident from the result the number of egg/plant was found lowest in 0.0 KgN/ha with lowest mean. The highest egg laying was found in 90 KgN/ha followed by 80 KgN/ha. The lowest number of egg/plant found in Imidacloprid 17.8SL. In different sixteen treatment combination (Nitrogen and Insecticide) the minimum egg laying observed in Imidacloprid 17.8SL+ 0.0 KgN/ha followed by Imidacloprid 17.8SL+ 70 KgN/ha , Imidacloprid 17.8SL+ 80 KgN/ha, Imidacloprid 17.8SL+ 90 KgN/ha.</p> AKSHAY KUMAR*, R.S.
