Abstract
The present research trial was carried out in the experimental area of Crop Diseases Research Institute (CDRI) Karachi, Pakistan during crop season of the year 2013. The experiment was laid out in accordance to randomized complete block design (RCBD) replicated thrice. Okra generally called as “lady finger” is mainly cultivated as vegetable crop in plain areas of the country. In the present study, we investigated the effect of three different organic fertilizers (Green Sun, Biophosphate, Nitrophos). Humic acid was also added @ 4 Kg ha-1 along with each treatment. Application of Green Sun @ 150 Kg ha-1 significantly affected plant height, number of leaves per plant, days to flowering. Whereas, Nitrophos applied at the same ratio significantly increased fruit length. Green Sun, Biophosphate and Nitrophous significantly affected capsule circumference, number of capsules per plant, capsules weight and total capsule weight per plant verses control, whereas all the three treatments had non-significant effect in comparison with each other.
