Growing Bush bean (Phaseolus vulgaris L.) and Kangkong (Ipomea aquatica) using natural pesticides and organic fertilizers
Abstract
Two experiments were conducted to evaluate the use of natural pesticides to control pests in bush bean (Phaseolus vulgaris L.) and to study the effect of different organic fertilizers on growth and yield of Kangkong (Ipomea aquatica). In the first experiment Neem Seed Kernel Extract (T1), Tobacco Décoction (T2), Cow Urine (T3), and Synthetic Insecticides (T4) were used as treatments to control common insect pests damaging bush bean. All the treatments were able to reduce insect damage when compared to control. No differences were observed among neem seed kernel extraction, tobacco decoction and cow urine in controlling bean fly (Phaseolus vulgaris), leaf miner (Liriomyza trifoli), leaf eating caterpillars (Hedylepta indicate), whitefly (Bemisia tabaci) and leaf eating beetles (Cerotoma trifurcate) of bean during vegetative stage. Pod borer damage was successfully controlled by Neem seed kernel extract. In the second experiment Cattle Slurry+Compost (T1), Organic Liquid fertilizer (AlgifolTM)+Compost (T2), Recommended Inorganic Fertilizer (T3), Compost (T4), Control (T5), Organic Liquid fertilizer (AlgifolTM) (T6) and Cattle Slurry (T7) were evaluated as fertilizers for growing Kangkong. Highest fresh and dry weight of the leaves were obtained with the application of Cattle slurry + Compost (T1) and inorganic fertilizer (T3). This shows that Kangkong grows best with fertilizer having high nutrients and they are easily available. Mean differences of fresh and dry weight of Kangkong yield among Compost (T4), Algifol (T6) and Cattle slurry (T7) applied treatments were non-significant (P=0.05). This study shows that Bush bean and Kangkong can be grown successfully using organic methods.
