Fertilizer is extremely essential to increasing the yield of vegetables. However, excessively using fertilizers has had a negative impact on the yield and quality of vegetables as well as soil environment in recent years. Non-heading Chinese cabbage ‘yellow rose’ was applied to determine the influence of organic manure and inorganic fertilizer on the character of rhizosphere soil, the growth and quality of plants. There were five treatments: conventional fertilization (NF), a total nitrogen reduction of 20% (NF20), a total nitrogen reduction of 30% (NF30), a total nitrogen reduction of 20% with 100 kg·667 m−2 bio-organic fertilizer (BNF20) and a total nitrogen reduction of 30% with 200 kg·667 m−2 bio-organic fertilizer (BNF30). The results show that the content of nitrate nitrogen, organic matter in rhizosphere soil treated by BNF20 and BNF30, was significantly enhanced compared with NF. The yield, Vc and soluble protein of plants treated by BNF20 and BNF30 increased by 30.11%, 17.26%, 5.66% and 15.90%, 16.02%, 5.37%, respectively, compared with NF. On the contrary, the nitrate content significantly decreased in plants of BNF20 and BNF30 by 47.87% and 40.98% compared with NF. The significantly positive correlation was observed between nitrate nitrogen content in rhizosphere soil and the yield (p < 0.05). In conclusion, reduced nitrogen with bio-organic fertilizer can improve the yield and quality of ‘yellow rose’ cabbage by improving the quality of rhizosphere soil.

Effect of organic (biogrcen) and inorganic fetilizers (ammonium sulphate and SP36) on the yield and quality of the temanggung tobacco in andosol soil was studied at Galapansari - Temanggung, from Februai to December 2001. The organic and inorganic fetilizers were formulated in 10 packages, namely : (1) 570 kg ammonium sulphate (AS) ♦ 100 kg SP36; (2) the recommended rate for temanggung tobacco (20 000 kg stable manure 500 kg AS + 100 kg SP36; (3) 5 000 kg organic fetilizer (OF); (4) 7 500 kg OF; (5) 8 500 kg OF; (6) 10 000 kg OF; (7) 12 500 kg OF; (8) 14 500 kg OF; (9) 7 500 kg OF + 3 500 kg sUble manure (SM); (10) 7 500 kg OF + 4 500 kg SM. All the rates of fetilizers were based on one hectare planted area (16 500 plants) The expeiment was designed as a randomized block in four replicates. Results showed that organic fertilizer waa more effective than stable manure in improving die growth, yield and quality of temanggung tobacco. A the rate of 5 000 kg was sufficient to produce high ( 6 313 kg fresh or 800 kg sliced died leaves), grade index (51.68) and crop index (55.31). Key words : Organic fetilizer, ammonium sulfate, SP36, temanggung tobacco, andisol

In 2005-2015. studied the effect of liquid organic fertilizer BIOOD-1 as foliar feeding on the yield and quality of various potato varieties in changing meteorological conditions. According to the results of the experiments, it was established that the most stable yields under various weather conditions were shown by the potatoes of the mid-season variety Bryansk delicacy. The low starch content of varieties Nevsky, Udacha was noted in years of high humidity, but with a lack of moisture, the starch content of these varieties increased in the background variant and in the experiment with organic fertilization.

This research aims to find out the effect and functional relationship of coconut ash organic fertilizer application on the increasing yield and quality of waxy corn. There are seven treatments of coconut ash fertilizer dosage, i.e. 0.00 ton/ha, 0.75 ton/ha, 1.50 ton/ha, 2.25 ton/ha, 3.00 ton/ha, 3.75 ton/ha, and 4.50 ton/ha. Data is analyzed using one way anova, t test for 2 independent samples, and simple linear regression analysis. Fertilizer dosage has significant effect on ear height position from soil surface, the number of seed row on ear, ear weight with and without dried husk, waxy corn production with and without dried husk, and starch, amilose, and amilopectin contents. The highest average of ear height position and the amount of seed row is obtained at dosage 0.75 ton/ha. Dosage 2.25 ton/ha gives highest average for ear weight with and without dried husk, while dosage 3.75 ton/ha results highest average for variables of waxy corn production with and without dried husk. Dosage 3.75 ton/ha also gives highest average for starch and amilopectin contents and lowest average for amilose content. One way relationship happens between fertilizer dosage with ear height position, the amount of seed row, ear weight, waxy corn production, starch and amilopectin contents.

Plants are naturally growing on the soil without hampering the eco-friendly environment. Intensive cultivation of crops with high yielding verities (HYV) hampering the soil health resulting unfertile soil. In addition, frequent uses of chemicals as well as overdose of synthetic fertilizer creating hazardous environment for the living things. However, to meet up the demand of foods as well as other basic requirements of increasing population of the world crop cultivation techniques need to be modernized. To overcome this situation, application of organic fertilizer need to apply regularly. Biochar can be a good source of organic fertilizer and it is currently using to improve the soil health globally. To examine the effect of biochar on jute growth and yield an experiment was set up in two different locations (Jute Agriculture Experimental Station (JAES), Manikganj, and Jute Research Sub Station (JRSS), Jashore of Bangladesh) during the period from August to December, 2019. Results revealed that location (JAES) had significant and positive effect on jute physiology and seed yield and as well as seed quality. Among fourteen treatments, treatment T2 (Recommended dose of fertilizer (RDF)) showed the highest plant height (163.5 cm), base diameter (7.44 mm) and pod per plant (16.5) compare to the rest treatments. Treatment T6 (RDF 75% + 25%[email protected]) showed the best seed weight (2.13 g) and seed yield/ plant (3.98 g) among all treatments. Interaction among treatments and locations, T2 x L2 affected seed germination (99%) and field emergence (92.33%) positively. From this research it was cleared that biochar alone may not enough but combination is required for improving jute seed yield and quality.
