Aims: This study was conducted to formulate appropriate fertilization scheme for some rice varieties used at University Income Generating Project (UIGP) sites of Central Mindanao University (CMU), Philippines and to determine the effects of organic and inorganic fertilizers on some soil chemical properties. Study Design: Split-plot in Randomized Complete Block Design (RCBD) in three replications with 5 levels of inorganic and organic fertilizers as main plot factor and 3 rice varieties as sub-plot factor. Place and Duration of Study: UIGP area of CMU, Musuan, Bukidnon, the Philippines from November 2015 to May 2016. Methodology: Plots were laid out following Split-plot in RCBD in 3 replications. The 5 levels of Fertilizers were: no fertilizer (control), 90-60-60 kg NPK/ha, 2t vermicompost/ha, 45-30-30 kg NPK/ha + 2t vermicompost/ha and 90-60-60kg NPK/ha + 2t vermicompost/ha while the three rice varieties were: Matatag 11, NSIC Rc158 and NSIC Rc238. The initial characteristics of the soil served as the basis for the recommended rate of inorganic fertilizer application at 90-60-60 kg NPK/ha. Results: Analysis of variance showed that interaction between the levels of fertilizers and varieties were not significant for all agronomic and yield parameters except the number of days to 50% flowering implying that the varieties had a similar response to the levels of fertilizers. Results revealed that the levels of fertilizers significantly affected plant height at 30 (P = 0.011) and at 50 days after transplanting, DAT (P = 0.006), productive tiller count (P = 0.002), % filled grains (P = 0.026), and grain yield (P = 0.003) while the varieties significantly differed in plant height at 50 DAT (P = 0.006), number of days to 50% (P = 0.001) and 100% flowering (P = 0.001), % filled grains (P = 0.039), 1,000 grain weight (P = 0.009) and grain yield (P = 0.044). When averaged across varieties, grain yields were increased by fertilizer application with 90-60-60 + 2t vermicompost/ha giving significant increase of 2.14 t/ha (vs control) and 90-60-60 kg NPK/ha, 2t vermicompost/ha, and 45-30-30 + 2t vermicompost/ha giving not significant increases of 1.26, 0.36 and 1.05 t/ha, respectively. NSIC Rc238 had the highest grain yield that was significantly higher than that of NSIC Rc158 but not with that of Matatag 11. Moreover, soil pH, organic matter and extractable phosphorus (P) contents of the experimental plots after harvest were significantly influenced by vermicompost and inorganic fertilizer application (P = 0.01) with plots applied with vermicompost exhibiting significantly higher pH values and organic matter contents compared to those plots with no fertilizer and those applied with inorganic fertilizers alone. Conclusion: Findings of the study disclosed that vermicompost is an effective organic amendment to improve soil pH, soil organic matter content and rice productivity in Maapag soil and its application at 2t/ha in combination with 90-60-60 kg NPK/ha gave the highest grain yields of Matatag, NSIC Rc158 and NSIC Rc238 at 6.23, 6.10 and 6.75 t/ha, respectively that were higher than their average yields but lower than their maximum yields.

Organic And Inorganic Fertilizers

Rice is the most important staple cereals in human nutrition and consumed by 75% of the global population. Rice plant needs supply of essential nutrients for its optimal growth. Rice production has been increased tremendously in India after green revolution combined with insensitive irrigation and use of inorganic fertilizers and pesticides. However, the effect of using inorganic fertilizers has resulted in contamination of ground water and decreased the productivity of soil, which in turn affects the rice production in long term. Use of organic manure may help to regain the soil health but they are insufficient to provide the essential nutrients to achieve optimal growth. So, use of organic manures combine with inorganic fertilizers are followed to obtain optimum yields. This study aimed to test the effect of the different organic fertilizer and combinations of organic and inorganic fertilizers on the qualitative and quantitative parameters of two cultivars of rice as DRR Dhan 39 and RP.BIO.226. The experiment was conducted on the farm located at Fasalwadi village, Sangareddy district, Telangana during kharif season in randomized complete block design with three replications. The treatment included two controls and 10 combinations of four organic fertilizers as farmyard manure, vermicompost, Panchagavya, Jeevamrutha and inorganic fertilizers as combination of 60:75:75 levels of N, P and K. Grain and straw samples were collected and physical parameters were measured at harvest stage. The results indicated that the variety DRR Dhan 39 gave the statistically significant (P<0.0001) higher grain yield of 8713 kg/ha and straw yield of 9483kg/ha with 50% organic fertilizers of Vermicompost, Jeevamrutha 5% and Panchagavya 3% and 50% inorganic fertilizer of NPK. On the other hand, the variety of RP.BIO.226 gave the highest grain yield of 6390 kg/ha with Vermicompost, Jeevamrutha 5% and Panchagvya 3% (8 t/ha, foliar spray and 500 litres/ha) and highest straw yield of 7430 kg/ha with T10 treatment (50% organic fertilizers of Vermicompost, Jeevamrutha 5% and Panchagavya 3% and 50% inorganic fertilizer of NPK). Both varieties of rice poorly responded to inorganic fertilizers with lower grain and straw yield. Statistically significant differences were observed in both varieties of grain crude protein (CP%), straw acid detergent fiber (ADF%), crude fiber (CF%) and acid detergent lignin (ADL%) with different fertilizers

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh from June to December 2015 to investigate the effect of spacing and fertilizer management on the yield of transplanted Aman rice cv. BRRI dhan39. The experiment comprised of five spacings viz. 25 × 5 cm, 25 × 10 cm, 25 × 15 cm, 25 × 20 cm, 25 × 25 cm and four fertilizer schedules viz. no manure and no fertilizer (control), recommended dose of inorganic fertilizer (80-60-40 kg N, P2 O5 , K2 O ha-1, respectively + 60 kg ha-1 gypsum + 10 kg ha-1 ZnSO4 ), 75% recommended dose of inorganic fertilizer + cow dung at 5 t ha-1, 75% recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha-1. The experiment was laid out in a Randomized Complete Block Design with three replications. Plant height (104.60 cm), number of total tillers hill-1 (11.03), panicle length (22.25 cm), grains panicle-1 (109.00) and grain yield (4.42 t ha-1) were found to be the highest in 25 × 15 cm spacing. Regarding nutrient management, 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha-1 superseded other treatments in terms of plant height (107.50 cm), number of total tillers hill-1 (10.40), number of effective tillers hill-1 (7.68), panicle length (22.26 cm), grains panicle-1 (111.70) and grain yield (4.14 t ha-1). The control treatment (no manures and no fertilizers) gave the lowest values for all these parameters. The highest grain yield (4.57 t ha-1) was found in 25 × 15 cm spacing combined with 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha-1 and the lowest grain yield (2.50 t ha-1) was found in 25 × 5 cm spacing combined with control (no manures and fertilizers). Therefore, 25 × 15 cm spacing combined with 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha-1 appeared as the promising practice in transplant Aman rice cv. BRRI dhan39 cultivation.

The experiment was carried out at Sunamganj district during November 2016 to May 2017 to observed the effect of urea fertilizer on the yield of boro rice varieties in haor areas of Bangladesh. Two factors experiment viz. Varieties BRRI dhan29 and BRRI dhan58; and six urea fertilizer levels including: 340 (F1), 320 (F2), 300 (F3), 280 (F4), 260 (F5), and 165 kg ha-1 (F6) [Farmer’s practice (FP)] were used. In case of F1-F5, the MoP-TSP-CaS04-ZnS04 as 127-112-75-11 kg ha-1 were used while Farmers’ practice (FP) was done with only 82 kg ha-1 TSP. The experiment was laid out in two factors randomized complete block design (RCBD) with three farmers’ replications. Data were collected on growth, yield and yield contributing characters of boro rice. Plant height varied at harvest stage in relation to variety and fertilizer. The tillers production hill-1 varied at harvest in case of variety and urea application. Higher plant height was found in BRRI dhan58 (93.9 cm) in comparison to BRRI dhan29 (90.3 cm). Plant height was also influenced due to urea fertilizers application. The higher tillers hill-1 (15.9), effective tillers hill-1 (12.3) and longer panicle length (21.1 cm) were produced by BRRI dhan58 at harvest compared to BRRI dhan29. The longest panicle (21.4 cm) was produced in the treatment F3 (300 kg urea ha-1). Higher number of sterile spikelets panicle-1 (58.5) and 1000-grain weight (23.2 g) was produced by BRRI dhan58. Higher number of grains panicle-1 (137.5) was produced by BRRI dhan29. The highest grain yield (6.7 t ha-1) and straw yield (7.91 t ha-1) were obtained in the treatment F3 (300 kg urea ha-1). The experimental soil analyses showed that the nutrient contents in post-harvest soils were higher compared to initial soil due to balanced fertilizer application. It is concluded that 300 kg urea ha-1 promoted highest grain yield.

[CABBAGE (Brassica olacea var. capitata) GROWTH AND YIELD AFFECTED BY COMBINATION OF ORGANIC AND INORGANIC FERTILIZER APPLICATIONS]. The use of organic fertilizer increasingly sought by farmers due to the increase in demand for organic products by consumers and also awareness of the sustainability of the land. The use of organic fertilizers in the cultivation alone could improve the soil quality but needs to be balanced with inorganic fertilizers to meet the nutrient adequacy. This study aims to examine the effect of organic and inorganic fertilizers combination on the growth and cabbage yield, and also to determine the most efficient dosage combination of organic and inorganic fertilizers. This research was conducted at the IPB Pasir Sarongge Experimental Station, Cianjur, West Java from November 2020 to February 2021. The study was compiled using RCBD with 4 replications and 7 treatments. The results showed the combination of 0.75 doses of inorganic fertilizer (150 kg/ha of urea, 75 kg/ha SP36, and 75 kg/ha KCl) and 3 tons/ha of organic fertilizer could increase 14.87 to 15.44% plant height and the number of leaves at 12.82 -15.11% compared to the same dose of inorganic fertilizer treatment alone. The combination of 1 dose (200 kg/ha of urea, 100 kg/ha SP36, and 100 kg/ha KCl) inorganic fertilizer application and 2 tonnes/ha of organic fertilizer could increase 50,60% yield/plot and yield/ha cabbage than 1 dose of inorganic fertilizer treatment..

The study evaluated the effects of organic and inorganic fertilizers on the growth and yield of two lowland rice varieties; determined the proper fertilizer combination; and evaluated the profitability of rice production as influenced by the combined application of organic and inorganic fertilizers. This was laid out in split plot arranged in a RCBD design with variety and fertilizer treatments as the main plot and subplot, respectively. Results revealed that the period from sowing to heading, shoot dry weight, number of filled grains per panicle and weight of 1,000 grains were significantly influenced by the variety. The yield, yield components and harvest index (HI) were significantly influenced by fertilizer application. A significant interaction effect was noted on the period from sowing to heading as observed that inbred rice (NSIC Rc212) headed late than hybrid (TH82). Plants applied with 120-60-60 kg ha-1 N, P2O5 and K2O produced taller height, larger LAI, longer panicles, more productive tillers and filled grains, and consequently highest grain yield and HI. These plants also produced the heaviest root and shoot dry weights resulting to higher root shoot ratio compared to unfertilized plants. Highest net income was obtained in plants applied with inorganic fertilizer at the rate of 120-60-60 kg ha-1 N, P2O5 K2O due to high grain yield. Irrespective of fertilizer treatments, inbred rice was more profitable than hybrid. Highest production cost was incurred in plants applied with pure organic fertilizer due to the high cost of the material.

To evaluate the effect of different fertilizer application on soil fertility under polyculture cropping system (okra, water spinach and yard long bean), a field experiment was conducted in the oil palm reclamation soil at the research farm in ICA UTM-Pagoh. There were five treatments involved which were: (T1) no fertilizer, (T2) organic fertilizer, (T3) inorganic fertilizer, (T4) organic inorganic compound fertilizer and (T5) organic + inorganic fertilizer.  The initial and final soil samples were collected to study the effect of different types of commercial fertilizer application on soil pH, electrical conductivity (EC), moisture content, soil organic carbon (SOC), total nitrogen (TN), C/N ratio, soil organic matter (SOM), bulk density and nutrients (P and K) contents in the soil surface layer (0–15 cm) of the experimented site for 14 weeks. Results showed that the soil pH was the lowest with an average of 6.05 units in T5 and was significantly higher in T1 (8.23 units). The EC value in T5 is the highest with 172.4 ds/m and lowest in T1 with an average of 25.5 ds/m. T5 showed the highest soil moisture and soil organic matter with 15.81% and 4.01% respectively. The combine application of organic and inorganic fertilizers has increased SOC and TN values compared with the T1 (control) specifically, which resulted in 3.7% and 0.33% of SOC and TN concentrations, respectively (). Bulk density showed no significant different among all the treatment with the highest value was in T4 (1.22g/cm3) and lowest in T3(1.05g/cm3). The average amounts of C/N ratio ranged from 11.11 to 13.60 between all treatments with the highest ratio in T4 (13.6). The average P and K contents were highest in T5 (1564.7 mg/kg and 1056.2 mg/kg). Thus, it showed that the application with the mixture of organic and inorganic fertilizer (T5) improved the soil condition.

Abstract This study explores the causal association between organic and inorganic fertilizer application and vegetable productivity in Ghana. Primary data were obtained from 300 pepper, cabbage and lettuce producers. To correct for self-selection bias and endogeneity, Heckman selection and three-stage least-squares models were estimated. More producers used inorganic fertilizers for pepper, cabbage and lettuce production than those who used organic fertilizers. Vegetable producers applied higher quantities of organic fertilizers (2830 kg) per acre than inorganic fertilizers (880 kg). Organic cabbage and lettuce producers recorded higher productivity than inorganic producers, but inorganic pepper producers had higher productivity than organic producers. However, vegetable producers who applied either organic or inorganic fertilizers, or both, recorded higher productivity than those who did not apply fertilizer. Factors that enhance the application of organic and inorganic fertilizers and vegetable productivity are education, farm size and production for export, land ownership, farmer association membership and perception about fertilizer price. Organic and inorganic fertilizer application improves vegetable productivity, and productivity promotes fertilizer application. Private agencies and government should subsidize fertilizers, improve producers' access to agricultural information, and train producers on productivity-enhancing agronomic practices.

The effects of organic and inorganic fertilizers on the growth and yield performance of soybean was evaluated at ALIAS R & DE Center, Pampanga State Agricultural University, PAC, Magalang, Pampanga from December 2017 to March 2018. It was laid out in the field according to the procedures of randomized complete block design (RCBD) with three replications. The treatments tested were T1 – No fertilizer application, T2 – 500 kg/ha of Power Organic, T3 – 21.74 kg/ha of Urea and 150 kg/ha of Super Phosphate, T4 – 250 kg/ha of Power Organic + 10.87 kg/ha of Urea and 75 kg/ha of Super Phosphate, T5 – 375 kg/ha of Power Organic + 5.44 kg/ha of Urea and 37.5/ha of Super Phosphate, T6 – 125 kg/ha of Power Organic + 16.31 kg/ha of Urea and 112 kg/ha of Super Phosphate. Results revealed that all organic and inorganic fertilizers applied crops were significantly different in terms of days to flowering, plant height at flowering, length of pods, weight of 100 seeds and computed seed yield per hectare. Cost and return analysis reveals that the highest net income and return of investment was derived from the combination of 50 % organic and 50 % inorganic fertilizer. Conjunctive use of organic and inorganic fertilizer, that is, 50 % recommended rate of organic fertilizer (Power organic) along with 50 % recommended rate of inorganic fertilizer (Urea and Super Phosphate) can enhance the growth and yield performance of soybean and can help the farmer to increase their production with higher net income.
