abstract 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.
Residual Effects Of Organic Manures With Different Levels Of Chemical Fertilizers On Rice
A field experiment was conducted to evaluate the residual effects of organic manures and different level of recommended fertilizer dose (RFD) on the yield and nutrient uptake of BBRI dhan29 at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh. The experiment containing seven treatments were laid out in a randomized complete block design with three replications. The treatments were T 0 (Control), T 1 (100% RFD), T 2 (75% RFD + residual effect of CD 5 t ha -1 ), T 3 (75% RFD + residual effect of PM 3 t ha -1 ), T 4 (75% RFD + residual effect of residual effect of Com. 5 t ha -1 ), T 5 (75% RFD + residual effect of CD 2.5 t ha -1 , PM 1.5 t ha -1, and Com 2.5 t ha -1 ) and T 6 (50% RFD + residual effect of CD 2.5 t ha -1 , PM 1.5 t ha -1 , and Com. 2.5 t ha -1 ). The manures viz. cowdung (CD), poultry manure (PD) and compost (Com.) was applied to the previous crop (T. Aman rice). The recommended doses of fertilizers were used to supply N, P, K and S @ 140, 15, 60 and 15 kg ha -1 , respectively to the present crop. Residual effects of organic manure with inorganic fertilizers significantly increased the yield attributes as well as grain and straw yields of rice. Treatment T 6 (50% RFD + residual effect of CD 2.5 t ha -1 , PM 1.5 t ha -1 , and Com. 2.5 t ha -1 ) produced the highest grain yield (6.87 t ha -1 ) and straw yield (7.24 t ha -1 ). The lowest grain yield (3.22 t ha -1 ) and straw yield (4.55 t ha -1 ) were found in T 0 (Control) treatment. Further, it was observed that T 2 (75% RFD + CD 5 t ha -1 ) performed better compared to T 3 (75% RFD + PM 3 t ha -1 ) and T 4 (75% RFD + Com 5 t ha -1 ) in exerting residual effects. The NPKS contents and uptake were markedly influenced by residual effects of manures and fertilizers. Therefore, treatment T 6 receiving 50% RFD along with the residual effect of 2.5 t ha -1 cowdung, 1.5 t ha -1 poultry manure and 2.5 t ha -1 compost was found to be the best combination of organic and inorganic fertilizers for obtaining the maximum yield of BRRI dhan29.

Field experiment was conducted at Agricultural College and Research Institute, Killikulam during Pishanam season (November- March) of 2015 – 2016. Higher Plant height, dry matter production, yield attributes realised superior grain yield and haulm yield with application of 75% N as inorganic fertilizer and 25% N as poultry manure (7160 kg/ha; 8090 kg/ha resp.) comparable with 25% N as vermicompost (6920 kg/ha; 7840 kg/ha resp.) and was followed 25% N as green leaf manure (6710 kg/ha; 7580 kg/ha). Higher physiological efficiency of 70.32 was attained when substituting 25% N as poultry manure and was followed by the same proportion of vermicompost. From the above results, it could be indoctrinated that application of 75 % of recommended N as inorganic fertilizer and substitution of 25% N either as poultry manure or green leaf manure is the desirable integrated nutrient management practice for achieving higher productivity under transplanted condition.

Nutrient management and fertilizer application are influential elements for high yield and preferred grain quality. Negligible information is available regarding fertilizer application in the paddy fields in Afghanistan. This research elucidates the efficacy of different fertilizers’ application on growth attributes, yield potential, and grain quality of rice. The treatments included the traditional application rate of nitrogen and phosphorus (RD), animal manure (AM), animal manure with 50% nitrogen and phosphorus of the traditional application rate (AMRD), sawdust (SD), and sawdust with 50% nitrogen and phosphorus of the traditional application rate (SDRD). Growth parameters, grain yield and its components, physicochemical properties, and morphological observation using scanning electron microscopy were recorded. The results revealed that the greatest panicle number, spikelet number, and grain yield were recorded in AMRD and SDRD treatments. Both AMRD and SDRD treatments increased ...

The study was carried out to investigate the effect of organic manures and chemical fertilizers on the yield of rice seed (Oryza sativa) during kharif 2015 at the Central Research Station in Farming System Research, OUAT, Bhubaneswar in a Randomised Block Design with 3 replications and 8 treatments having rice variety "Lalat ". From the experiment result, it was observed that the application of 100% NPK+25 Kg ZnSO 4 (T 7) produced the highest number of grain/panicle, 1000 grain wt., straw yield, grain yield with chaff, grain yield without chaff and harvest index whereas highest panicle and sterile grain/ panicle was recorded in T 8 (T 7 + residue recycling).
The experiment was conducted at the research field of Bangladesh Rice Research Institute (BRRI), Gazipur during Aman season of 2012 in applied on various inorganic fertilizers in soil and to evaluate the effect of nutrient content and uptake of T. Aman rice. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. There were seven treatments such as control, Recommended Fertilizer Dose (RFD), 50% reduced rate of N, 50% reduced rate of P, 50% reduced rate of K, 50% reduced rate of S and 50% reduced rate of Zn. The highest grain yield of 6.16 t ha 1 was observed in the treatment 50% reduced rate of N which was statistically identical to those recorded in the treatments 100% recommended fertilizer dose and 50% reduced rate of P. effective tillers hill 1, filled grains panicle 1, 1000-grains weight had also higher in the treatment T3 and unfilled grains panicle lower in the treatment T3. However, plant height and panicle length 1 had higher in 50% reduced rate of P. It was observed that application of 50% reduction of N fertilizers from RFD affected non-significantly both in yield contributing traits, nutrient content and nutrient uptake by grain and straw of BRRI dhan49 compared to RFD. Grain yield was increased with increasing nutrient uptake by BRRI dhan49. Therefore, the treatment 50% reduced rate of N fertilizer performed better than RFD and other treatments.

The present study conducted entitled, "Effect of Integrated use Organic manure and Bio-fertilizers on crop productivity under Rice (Oryza sativa L.) crop". Involved field trial conducted during Kharif season of year 2016-17 followed by laboratory analysis of the plant and soil samples in the Department of Soil science & Agriculture Chemistry, Udai Pratap Autonomous College, Varanasi (U. P). All grasses were removed from the experimental plots and soil samples have been taken from each replication plots at 30 DAT, 60 DAT and at harvesting. The experiment was conducted under randomized block design (RBD) with six treatment combinations. Treatments were replicated thrice making the total number of 18 plots. The effect of various treatments on dry matter production could be arranged in order of T6>T3>T5>T4>T2>T1 and the values were 70.25, 62.15, 59.45, 43.40, 41.25 and 35.59 gm-1 row length, respectively. Application of fertilizers alone or in combination with F.Y.M increased grain and straw yield of rice significantly over control. Further, the yield was significantly superior under the use of organic manure and bio-fertilizers over the sole use of chemical fertilizers. On the basis of data, the superiority of the treatments may be arranged as T6>T3>T5>T4>T2 and T1. Like dry matter yield, rice grain and straw yield was also highest in treatment where 50% NPK was substituted through FYM to rice crop. The integrated use of fertilizers with FYM and bio-fertilizers might have added huge quantity of organic matter in soil that increased grain and straw yield. In general, higher number of tillers (15.25 m-1 row length), plant height (92.50 cm), dry matter at 60 DAT (70.25 gm-1 row length), grain yield (46.25 Qha-1) and straw yield (91.25 Qha-1) obtained with T6 treatment followed by T3>T5>T4>T2>T1 (control).
A rice cultivation study was conducted at Kyushu University farm. Cow manure (CM), poultry manure (PM), rice straw + urea mix-application (SU), urea (UF) and M-coat, a slow released compound fertilizer (M-coat) were used as the N sources by comparing with no application (Control). Treatments were made with two levels application of each N source at 40 (level I) and 80 kg N ha -1 (level II) excluding M-coat. In all urea treatments, three split applications were made. A study of soil incubation was conducted for 2 weeks to investigate the mineralized N of applied mineral and organic fertilizer. Plant growth characters, dry matter, yield and plant nutrient accumulations were higher in mineral fertilization than organic. Mineral fertilization was observed in correlation with the larger crop removal. PM-II as an organic matter provided comparatively higher nutrient accumulations which in turn enhanced the growth and yield of rice. CM and SU gave the lower plant growth, yield and nutrient accumulation. Mineralized N was higher in sole mineral N applications. Organic matter with high C/N ratio provided very low mineralized N and its net N mineralization percentage. Negative values of net N mineralization percentage were observed in SU due to N immobilization.

We investigated the effects of integrated organic and inorganic fertilizers on the growth and yield of indica rice variety Manawthukha and japonica rice variety Genkitsukushi. In a split-plot design, the two rice varieties were assigned as main plot factors, and the integrated treatments were the subplot factors, including no-N fertilizer (N 0), 50% chemical fertilizer (CF) (CF 50), 100% CF (CF 100), 50% CF + 50% poultry manure (PM) (CF 50 PM 50), 50% CF + 50% cow manure (CM) (CF 50 CM 50), and 50% CF + 50% compost (CP) (CF 50 CP 50). CF 100 was equivalent to N at 85 kg/hm 2. Manure was applied based on the estimated mineralizable nitrogen (EMN) level, which is dependent on total N (%) of each manure type. Manawthukha rice plants were taller with higher tiller number and dry matter content. However, higher soil-plant analysis development (SPAD) values were measured in Genkitsukushi throughout the crop growth period, resulting in higher seed-setting rate (%) and greater yield. At the same N level, CF 50 PM 50 application in both rice varieties resulted in higher SPAD values, plant height and tiller number than CF 100. CF 50 PM 50 containing total N more than 4% supplied synchronized N for the demands of the rice plants, resulting in maximum dry matter, yield and yield components. CF 50 CM 50 and CF 50 CP 50 treatments containing total N less than 4% resulted in lower yields which were similar to CF 100. These results indicated that integrating organic and inorganic fertilizers enhanced growth parameters and yields of Manawthukha and Genkitsukushi, while reducing the dose of chemical fertilizer.
