The differences among treatment means were compared using Tukey’s Honest Significance Difference at 1% level of significance. The treatments were as follows: T1 – untreated (water) T2 – chemical check + 16 L of water T3 - 15.75L of water + 250 ml of Neem Extract T4 - 15.50L of water + 500 ml of Neem Extract T5 - 15.25L of water + 750 ml of Neem Extract T6 - 15L of water + 1000 ml of Neem Extract.
