“…This capacity of producing more fruit is probably due to high nitrogen content of urea which could favour the photosynthetic activity of the plant. This result corroborates that of Akande et al (2003) who reported that urea increases productivity and improves yield. Contrary, Awodun (2007) observed that more fruits are produced in response to applying foliar fertilizer than urea.…”

Okra contributes an important part of the diet to many people in the tropics, more especially in Cameroon. But its production is seriously affected by poor soil fertility. In other to mitigate this problem, a field experiment was conducted from April to august 2016 at Institute of Agricultural Research for Development (IRAD) Nkolbisson-Yaoundé with the main objective to evaluate the effects of different soil amendments on the performance of okra (Abelmoschus esculentus L.) crop. The experiment was laid out using a randomized complete block design (RCBD) with three replications and eleven treatments: (Tithonia leaves (6700 kg/ha), piggery manure (6700 kg/ha), foliar fertilizer (0.6 kg/ha), urea (200 kg/ha), NPK20-10-10 (200 kg/ha), Tithonia leaves (3350 kg/unit) + NPK20-10-10 (100 kg/unit), Tithonia leaves (3350 kg/unit) + Urea (100 kg/ha), urea (100 kg/ha) + NPK 20-10-10(100 kg/ha), Tithonia leaves (100kg/ha) + foliar fertilizer (0.3 L/ha), Tithonia leaves (3350 kg/ha) + piggery manure (3350 kg/ha) and control (0 kg/ha). The Results showed that the growth and yield of okra were significantly (P<0.05) affected by different soil amendments. The number of days to achieve 50% shoot set was significantly (P<0.05) greater (50.66±1.24) with the use of NPK 20-10-10 as compared to the rest of the treatments. The number of days to achieve 50% flowering was significantly (P<0.05) greater (59.33±1.46) with the use of Tithonia leaves as compared to the rest of the treatments. The tallest plants and highest number of fruits per plant were recorded from the urea treatment, while the use of foliar fertilizer resulted in many branches and leaves per plant. A combination of NPK and Tithonia leaves resulted in heavy fruits per plant. NPK treatments produced the highest number of fruits and the heaviest fruits as compared to the foliar and control treatments. From the results obtained, it can be concluded that the application of foliar fertilizer, urea and NPK 20-10-10 + Tithonia and NPK which recorded the highest growth and yield parameters among all the treatments are the best treatments and should be adopted by farmers in the study area to maximize their yields. However, further studies on other combinations of organic fertilizers need to be carried out in different areas in order to come out with desired new alternatives that will reduce the use of high quantity of inorganic fertilizers.

“…Application of 50% NPK+50 PM proved most effective in ensuring good performance in terms of growth and fresh fruit yield of ladies finger in valley soils of Chittagong, Bangladesh. In agreement with these results, Akande et al [26] reported that combined use of ground rock phosphate applied together with poultry manure significantly improved growth and yield of Okra (Abelmoschus esculentus L Moench) compared to application of each material separately. Poultry manure has long been recognized as the most desirable organic fertilizer.…”

There were six treatments-control (no fertilizer/poultry manure/compost), full NPK @ 120 kg N ha-1 , 60 kg P ha-1 and 80 kg K ha-1 , full poultry manure (PM) @ 30 ton ha-1 , 50% NPK+ 50% PM, full kitchen waste compost @ 30 ton ha-1 , and 50% NPK+ 50% compost. The treatments were arranged in randomized block design with three replications. The data collected were number of leaves, plant height, fruit length, fruit circumference, number of fruits and fruit yield. The results showed that full NPK fertilizer did not increase the growth and yield of ladies finger over control. Application of poultry manure, compost and their combination with NPK fertilizers significantly influenced the growth and yield. However, the combined application of 50% NPK+50% PM showed the best ladies finger performance compared to other treatments in the valley soils of Chittagong.

“…They observed a great increase in yield of okra when NPK fertilizer was combined with organomineral fertilizer. Akande et al [23] also reported that combined use of ground rock phosphate applied together with poultry manure significantly improved growth and yield of Okra (Abelmoschus esculentus L Moench) compared to application of each material separately.…”

A field experiment was conducted in the crop field of the Department of Soil Science, University of Chittagong, Bangladesh to study the effects of biogas plant residues, poultry manure and NPK fertilizer on growth and yield of ladies finger (Abelmoschus esculentus L Moench). There were six treatments -control (no fertilizer/poultry manure/compost), full NPK @ 120 kg N ha -1 , 60 kg P ha -1 and 80 kg K ha -1 , full biogas plant residues(BPR) @ 30 ton ha -1 , 50% NPK+ 50% BPR, full poultry manure (PM) @ 30 ton ha -1 , 50% NPK+ 50% PM. The treatments were arranged in randomized block design with three replications. The data collected were number of leaves, plant height, fruit length, fruit circumference, number of fruits and fruit yield. The results showed that full NPK fertilizer did not significantly increase the growth and yield of ladies finger over control. Compared to control addition of full poultry manure and its combination with NPK fertilizer resulted in 6.28 to 7.29 fold increases in yield. were obtained in treatments with biogas plant residues compared to treatments with poultry manure. Our result indicate that poultry manure can be used in combination with the application of inorganic fertilizers for better growth and yield of ladies finger in the valley soils of Chittagong.
