Effect of Spraying By Organic Fertilizers and Growing Point Pinching On the Growth and Yield of Okra. (Abelmoschus esculentus Ls.)

An experiment was conducted in agricultural college arboretum that belong to tishreen university on okra during the growing season of 2013-2014 to investigate the effect of spraying by organic fertilizers and growing point pinching on the growth and yield. The experiment include 8 treatments as control (without spraying by organic fertilizers or growing point pinching), two kinds of organic fertilizers (ultra humic acid and amino vega) with or without growing point pinching. Plots were completely randomized over the experimental area having four replicates for each treatment. Each replicate contained 14 plants. Results showed that the highest values of vegetative growth parameters are stem length branch number ,leave number per plant due to the interaction between pinching of growing point and spraying by ultra humic acid and amino vega . The experiment results revealed also ,that the highest yield and The largest number and weight of fruits was produced from growing point pinching and spraying by ultra humic acid and amino vega, compared to all other treatments.

Test the effectiveness of some organic and amino compounds in the growth and production of tomato (Solanum Lycopersicum L. ) under greenhouses conditions

The research aims to study the effect of certain organic and amino compounds in the growth and production of tomato under green houses conditions.Hulay F1 hybrid tomato and two organic commercial vehicles differing in composition Hupost and Boldouzerwere used.The experiment done in a way randomized complete blocks designed , with three replicates per treatment , and 10 plants per replicate . Seedlings WERE Prepared in beet moss using trays of Alstrepor inside the greenhouses.
