The Effect of Organic and Inorganic Fertilizers on The Growth and Results of Green Mustard (Brassica rapa L.). Green mustard (Brassica rapa L.) is a vegetable that preferred by many consumers, this causes many farmers cultivate this vegetables. One of the important factor in the cultivation of green mustard is fertilizer type. Alternative to improve soil quality and fertility is by providing organic matter. A field research was conducted to evaluate the effect of organic and inorganic fertilizers on the growth and yield of green mustard, in Banjar Taman Tande, Baturiti Village, Bedugul from April to June 2018. This study was designed with a Randomized Block Design with nested patterns consisting of two factors. The first factor was the type of fertilizer, which was consisted of four types of organic fertilizer, namely: vermicompost, cow manure, chicken manure, goat manure and inorganic fertilizers (NPK Mutiara). The second factor was fertilizer dosage, which was consisted of three levels, namely: 0 tons/ha, 15 tons/ha, and 30 tons/ha, while for NPK Mutiara fertilizer dosages, namely: 0 kg/ha, 150 kg/ha, and 300 kg/ha.The results showed that the effect of organic and inorganic fertilizers were not significantly different on the growth and yield of green mustard plants and RAE values. The total N content of soil on vermicompost treatment was 0.23% equal to NPK Mutiara. The total population of soil microbes on vermicompost treatment under dosage of 15 tons/ha and 30 tons/ha were 1.4 x 106 cfu/g that was much higher compared to NPK Mutiara 150 kg/ha fertilizer (0.3 x 106 cfu/g).

This study was carried out to ascertain the effects of organic manure (farmyard manure, poultry manure, and vermicompost) and chemical fertilizers NPK (nitrogen, phosphorus, and potassium) on the growth and yield of onion. The research was consisting ten treatments with three replications. Different levels of nitrogen (0, 100, and 150 kg ha-1), phosphorus (0, 75, and 100 kg ha-1), potassium (0, 80, and 100 kg ha-1) fertilizers, and various rates of organic manures (20 ton ha-1 of farmyard manure, 20 t ha-1 of poultry manure and 15 t ha-1 of vermicompost) were applied to the soil at different combinations. The results of this study have shown that both inorganic fertilizers and organic manures significantly influenced all growth and yield parameters. Whereas, maximum plant height (50.50 cm) and bulb yield (30.75 t ha-1) were obtained at the combination of 20 t ha-1 farmyard manure + 150 kg ha-1 N + 100 kg ha-1 P2O5 + 100 kg ha-1 K2O. However, the minimum bulb yield (15.80 t ha-1) was observed with control where no fertilizer was applied. Therefore, application of 20 t ha-1 farmyard manure during field preparation followed by application of 150 kg ha-1 N + 100 kg ha-1 P2O5 + 100 kg ha-1 K2O can be recommended for optimal growth and maximum bulb yield of onion.

Red rice was one species of rice in Indonesia that was superior in nutritional content and selling price compared to white rice but the productivity of red rice is still low. One of way to improved rice growth and productivity is fertilization red rice was one type of rice in Indonesia that contains high nutrition. This research aimed to observe the effects of  the combination of organic and inorganic fertilizers on the growth and yield of red rice (Oryza nivara L.). The research used a Randomized Completely Block Design (RCBD) with 7 treatments. Each treatment had 3 replications and each experiment unit consisted of 3 plants so that there were 63 plants. The best treatment was compost of oil palm empty fruit bunch (125 g) + N, P, and K fertilizer 50%. The highest production was on oil palm empty fruit bunch compost (125 g) + Fertilizer N, P and K 50%,  it was equivalent to 5.49 ton/ha. In the red rice crop farming system it can be recommended to provide a combination of oil palm empty fruit bunch (125 g) compost and 50% N, P and K fertilizer to increase yields in the cultivation of red rice.

Soil fertility and maximum crop production can only be achieved through proper fertilization. Proper and balanced fertilization have a considerably positive effect on plant growth and yield. Due to continuous use of chemical fertilizers, the organic matter and nutrient content of the soil decreased gradually. Therefore, in modern era, agriculture scientists are now engaged to establish an agricultural system, which can not only lower the production cost, but also conserve the natural resources. Soil, as a source of nutrients, must be protected from various kinds of external factors, especially from the addition of fertilizers in excessive rates. Any degradation in the quality of soil can significantly produce many undesirable changes in the environment and also reduces the overall crop yield. So, the concoction of organic and inorganic fertilization is an alternative and most effective method for sustainable and cost-effective management for maximum crop production, without effecting the environment. The Integrated Nutrient Management provides an excellent opportunity not only for sustainability of the soil, but also enhances the overall crop productivity. The present review study was carried out with the main aim to evaluate the role of combined application of organic and inorganic fertilizers on wheat crop production. The outcome of the study concluded that combined application of both organic and inorganic fertilizers significantly improve the wheat crop production, as compared with the sole application of either organic or inorganic fertilizers.

The objective of the experiment was to evaluate the influence of organic and inorganic fertilizers on growth and yield of two onion varieties in the transitional zone of Ghana. The experiment was laid out in a split plot design with 3 replications. Two varieties [Bawku Red and Red Creole] were laid as main plots and fertilizer rates [10 t/ha Cow dung, 10 t/ha Poultry manure, 300 kg/ha NPK, 5 t/ha PM + 150 kg/ha NPK, 5 t/ha CD + 150 kg/ha NPK) and control (without amendment)] were assigned to sub-plots. The two field experiments were conducted in 2016 and 2017 cropping seasons at the research field of the College of Agriculture Education, University of Education Winneba, Mampong campus. The result showed that Bawku Red planted on 5 t/ha PM + 150 kg/ha NPK produced (P=.05) higher number of leaves per plant and shoot fresh and dry weight than the control during the 2016 cropping season. Red Creole planted on 10 t/ha PM had higher number of leaves per plant, taller plants and higher marketable bulb yield than the control during the 2016 cropping season. In both 2016 and 2017 cropping seasons, Bawku Red and Red Creole planted on 5 t/ha PM + 150 kg/ha NPK produced (P=.05) higher total bulb yield than the control. For maximum vegetative growth and yield in onion production, preferably Bawku red, sole poultry manure (10 t/ha) and/or in combination with NPK (5 t/ha PM+150 kg/ha NPK) is recommended.
