Organic manures as a source of plant nutrients for cultivation of field crops has received worldwide attention due to rising costs, rapid nutrient loss and adverse environmental impacts from inorganic fertilizers. A pot experiment was conducted in the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh to observe the effects of cow dung on growth, yield of stevia along with post-harvest fertility status of soil. Four treatments of CD viz. 0, 5, 7.5 and 10 t ha -1 in two contrasting soils (acid and non-calcareous) were examined following Completely Randomized Design (CRD) with three replications. Growth and yield attributes increased significantly with the advancement of growth period (60 DAP) and increased rate of CD up to 10 t ha -1 . An overall performance of noncalcareous soil was better than acid soil. In non-calcareous soil, the leaf biomass yield was increased by 275% whereas in acid soil it was 268% over control. The acidity of both soils significantly decreased with the increased rate of CD. All essential plant nutrients viz. total N, available P exchangeable K, Ca, Mg, available S, Zn, B and organic matter content of soil were significantly increased with the increased levels of CD up to its highest dose (CD @ 10 t ha -1 ) in both soils. Thus from the findings of the present research work it can be concluded that for getting optimum leaf biomass yield of stevia along with fertility of both soils CD should be applied @ 10 t ha -1 .

“…Identical leaf area was also obtained from the plants fertilized with CD 7.5 and CD 5 in non-calcareous soil. Similar type of result was found by Uka et al (2013) in the cultivation of okra. The lowest leaf area was found from the control treatment irrespective of soils used.…”

“…PM application at all levels increased fresh weight at harvest by 13.06 to 28.20 g plant -1 in acid soil and 14.73 to 30.68 g plant -1 in non-calcareous soil. Similar type of result was reported by Uka et al (2013) in the fresh weight of okra. El-Dewiny et al (2006) also depicted that fresh weight of radish and spinach plants increased with increased application of sewage sludge.…”

Stevia represents an interesting species for the development of new ingredients characterized by a low caloric contribution having high antioxidant and phytochemical properties. As a valuable organic fertilizer, poultry manure (PM) serves as a suitable alternate to chemical fertilizer due to having higher total solid content than most other manures. The present study was conducted in the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh to evaluate the effects of poultry manure on growth and leaf yield of stevia and post-harvest soil fertility. The experiment was laid out in a Complete Randomized Design (CRD) with three replications. PM was applied at rates of 0, 5, 7.5 and 10 t ha −1. Data of the plant height, number of branches and number of leaves per plant were collected at 0, 15, 30, 45 and 60 days after planting (DAP). At harvest, leaf area, fresh weight, dry weight of leaves of stevia and post-harvest soil were evaluated. Plant that received 5 t ha −1 of PM was the best with respect to all the parameters assessed except post-harvest soil fertility. The contents of total N, available P, exchangeable K, Ca, Mg, available S, Zn and B were significantly increased with the increased levels of PM up to 10 t ha −1 in both soils. pH and soil organic matter content were also increased several folds and favored higher growth and yield of stevia. It can be recommended from the findings of the study that farmers should apply PM @ 5 t ha −1 to obtain maximum growth and leaf yield of stevia where as PM @ 10 t ha −1 can be applied for maintaining soil fertility in the agro-climatic condition of Bangladesh.

“…Okra ( Abelmoschus esculentus (L.) Moench) is a vegetable widely grown in tropical and subtropical regions (Torkpo et al , ; Jarret et al , ). It is called bamia or bamya in some parts of the world, particularly in Asia and the Middle East (Uka et al , ). This crop is generally considered as drought‐resistant and has fewer pests than soybean (Miller et al , ; Jarret et al , ).…”

The aim of this work was on one hand to investigate the influence of milling speed and mean particle size of granulometric classes of okra (Abelmoschus esculentus (L.) Moench) seed powders on proximal composition (related to nutritional potential). On the other hand, it was tried to relate flow properties to powder physicochemical characteristics, namely particle size distribution and proximal composition. Then, dry okra seeds were ground with an ultra-centrifugal mill at three rotational speeds, 6 000, 12 000 and 18 000 r.p.m., corresponding to circa 990, 3 958 and 8 906 g, respectively. Each powder was separated into four granulometric classes: ≥500, 315-500, 180-315 and ≤180 µm. Milling speed affected the particle size distribution of dry okra seed powders: on one hand, the higher the milling speed, the lower the mean particle size, mainly because of the higher the proportion of fine particles (<100 µm); on the other hand, at low milling speed, dry okra seed powders were rather monomodal and constituted of large particles, whereas at high milling speed they were bimodal and composed of two populations (fine and large particles). In granulometric classes, fat and protein contents were significantly higher for fine particles, unlike carbohydrate and ash contents that were lower. This differential distribution of macronutrients within granulometric classes was enhanced at higher milling speed. Finally, the ≤180 µm granulometric class, corresponding to the smallest mean particle size, had a low flowability, confirmed by their high cohesion and compressibility, which can be related to its high fat content making it sticky. On the contrary, the ≥500 µm granulometric class was not cohesive, leading to good flow properties.
