Relative effect of organic and inorganic fertilizers on the growth of okra [Abelmoschus esculentus (L.) Moench]

A greenhouse experiment was conducted to study the relative effect of organic and inorganic fertilizers on the growth of okra (Abelmoschus esculentus). The experiment consisted of four treatments. Cow dung and poultry droppings were applied at the rates of 2.5 kg per 10 kg of soil one week before sowing, while NPK fertilizer (15:15:15) was applied at the rate of 6 g per 10 kg of soil three weeks after sowing. The treatments were laid in a completely randomized design with three replications. Plant growth was assessed using plant height, fresh weight, leaf area and dry weight. The application of cow dung, poultry droppings and NPK fertilizer had significant effects on all the parameters assessed. The application of poultry droppings gave plants with the greatest plant height, leaf area and fresh weight, while cow dung application gave the greatest dry weight. The data obtained from these treatments were significantly higher than the data obtained from the control. It was, therefore, concluded that the use of organic manure in the production of vegetables like okra should be encouraged.

Fertilizer is one of the most important needs for plants. Fertilizing can be done by using inorganic fertilizers or organic fertilizers. Long term fertilizing by using inorganic fertilizers without adding the organic matter could potentially reduce soil fertility and lead to not optimal growth of the plant. This study aims to determine the effect of liquid organic fertilizer (LOF) made from rabbit urine, NPK fertilizer, and the combination of both fertilizers on the growth of bok choy, and to determine the best fertilizer dosage for the growth of bok choy. This study uses a Completely Randomized Design consisting of 2 factors, the dose of rabbit urine LOF and dose of NPK fertilizer; 4 dosage levels each in triplicates. Data was analyzed using ANOVA followed by DMRT Test. The results indicates that the application of LOF made from rabbit urine, NPK fertilizer, and the combination of both fertilizers increases plant height, leaves number, leaf area, wet weight, dry weight, and chlorophyll total of bok choy. DMRT (a 5%) test shows the best dosage applied for enhancing growth parameter are 6 ml of LOF plus 0,4 gram of NPK for plant height, wet weight, and dry weight, the 4 ml of LOF plus 0,6 gram of NPK for leaves number and leaf area, and the 4 ml of LOF plus 0,4 gram NPK for chlorophyll total.

Vegetative Characters

A field experiment was conducted in the upland of Muneng Probolinggo during early dry season (April – June 2015) to study the effect of manure and inorganic fertilizers on vegetative, generative growth, nutrient, and secondary metabolite contents of mungbean (Vigna radiata L.). The treatments consisted of (1) no fertilizer, (2) 10.4, 18, 60 kg of N, P, K ha-1, (3) 22.5: 22.5: 22.5 kg of NPK ha-1, (4) 5000 kg ha-1 manure, and (5) 11.25:11.25:11.25 kg of NPK ha-1 + 2500 kg ha-1 manure. These treatments were arranged in a randomized completely block design with three replications. Application of manure, inorganic fertilizer, and its combination significantly stimulated several vegetative characters especially number of nodes, number of clusters, fresh weight of biomass, and number of nodules. At the generative characters, application of manure and inorganic fertilizers also significantly increased pod dry weight and grain dry weight. Among all treatments, NPK inorganic fertilizer (T2) gave the highest vegetative and generative growth which was shown on biomass fresh weight, pod dry weight and grain dry weight per plant. NPK fertilizer and manure applications increased total flavonoid and phenolic contents as well as antioxidant activity. This combination treatment therefore, could be suggested in mungbean cultivation to increase seed quality.
