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.

J.Soil Sci. and Agric. Eng., Mansoura Univ, 2018
Balanced supply of essential nutrient is one of the most important factor for increasing rice yield. Hence, knowledge of interaction of N with other nutrients are very important for improving fertilizer use efficiency and consequently increasing rice yield. A Field experiment was carried out at Rice Research and Training Center experimental farm during 2016 and 2017 seasons to assess the influence of different combinations of N, P, K and Zn fertilizer on yield of Sakha105 rice variety, its attributes, NPK uptake, N-recovery efficiency and agronomic nitrogen use efficiency. The fertilizer combinations were: (1) control, (2) N, (3) N + P, (4) N + K, (5) N + Zn, (6) N + P + Zn, (7) N +K + Zn, (8) N + P + K, and (9) N + P + K + Zn. Yield and yield attributes of Sakha 105 rice cultivar were significantly affected by different combinations of N, P, K and Zn fertilizer. The NPKZn treatment resulted in the highest grain yield, number of panicles hill-1 , number of filled grain panicle-1 and lowest sterility percentage compared with the control. In addition, the uptake of N, P and K varied significantly by the application of different combinations of N, P, K and Zn fertilizer in both growing seasons. Nitrogen recovery efficiency % varied significantly with different fertilizers and ranged from 24.01 to 41.39% and from 26.08 to 43.99% in 2016 and 2017, respectively. The application of different chemical fertilizers significantly increased the available soil NH 4 + content and available soil P concentration at different days after transplanting compared with the control. The study suggests that balance nutrient application using N, P, K and Zn fertilizers is a key management strategy for sustaining soil fertility and therefore increasing rice yield.

The agronomic investigation was undertaken at Post Graduate Research Farm, Agronomy Section of Rajarshee Chhatrapati Shahu Maharaj College of Agriculture, Kolhapur (M.S.), India during kharif, 2019. The experiment was laid out in a split plot design with four replications and nine treatment combinations comprising of three varieties of rice V1-Indrayani, V2-Phule Radha and V3-Bhogawati as main plot treatments and three fertilizer levels F1-75% RDF, F2-100% RDF and F3-125% RDF as sub plot treatments on sandy clay loam soil. The variety Indrayani had the higher grain yield (59.50 q ha-1), straw yield (86.75 q ha-1) and harvest index (40.62%) which were statistically at par with Bhogawati and superior over Phule Radha. Grain yield (58.83 q ha-1), straw yield (87.73 q ha-1) and harvest index (40.06%) were also significantly maximum with the application of 125% RDF ha-1 which was at par with application of 100% RDF ha-1 and significantly superior over 75% RDF ha-1. The effect of interaction between rice varieties and fertilizer levels were significantly influenced the yield attributing characters. The rice variety Indrayani when applied with 125% RDF ha-1 exhibited significantly superior grain yield (64.62 q ha-1), straw yield (92.25 q ha-1) and harvest index (41.18%) over rest of all the remaining interaction combinations. The content of N, P and K in grain were (1.24%, 0.31% & 0.14%) and straw (0.78%, 0.19% & 1.49%) respectively, total uptake of nutrients were (142.66, 35.85 & 138.56 NPK kg ha-1) respectively by rice crop were found significantly maximum with the variety Indrayani followed by Bhogawati and which was superior over Phule Radha. Available N, P and K were (268.09, 36.42 & 277.17 NPK kg ha-1) respectively in soil after harvest was found significantly maximum with the variety Phule Radha followed by Bhogawati which was superior over Indrayani. The content of N, P and K in grain were (1.29%, 0.31% & 0.14%) and straw (0.79%, 0.20% & 1.49%) respectively, total uptake of nutrients were (146.35, 36.85 & 140.19 NPK kg ha-1) respectively by rice crop and available N, P and K were (267.24, 37.22 & 289.91 NPK kg ha-1) respectively in soil after harvest were found significantly maximum with the application of 125% RDF ha-1 which was at par with application of 100% RDF ha-1 and significantly superior over 75% RDF ha-1 .
A field experiment was conducted during kharif season of 2013 to study the effect of inorganic fertilizers with and without FYM on yield, number uptake and quality parameters (protein content) of rice var Narendra 359 (NDR-359). The 13 treatments consisted of NPK (120-60-60), sulfur (40 kg ha-1) and zinc (5 kg ha-1) with FYM @ 10 t ha-1 and without FYM. The grain and straw yields increased with an increase integration of FYM treatment i.e. N120P60K60S40Zn5 + FYM, (60.32 q ha-1 and 73.69 q ha-1). respectively computed (approx) 123 and 129% higher as compared to absolute control. The application of graded doses of inorganic fertilizers without FYM i.e. N120P60S40Zn5 (T12) showed significantly higher grain and straw yields computed 107 and 112% higher in comparison to the lowest at absolute control (24.55 q ha-1). It was observed that the number of tillers m-2, plant height and 1000 grain weight increased with increase graded levels of inorganic fertilizers with FYM than without FYM on similar dose. The total uptake of N, P, K, S and Zn found to significantly increased with the application of graded dose of fertilizersalong with FYM. The effect of these nutrients also affected a significant imporvement in protein content in grain. Thehighestproteincontent8.43% and 2.43% in garin and straw obtained with FYM in treatment (T7) than lowest in absolute control (6.31 and 0.56% respectively). So treatment (T7) N120P60K60S40Zn5 + FYM was to be foundbest dose for most of the characters of the crop under study.

The decline in rice yields as a result of excessive chemical fertilizer (CF) inputs is a matter of great concern in rice-growing regions of Asia. In two-year’s field experiments, the nitrogen, phosphorus, and potassium (NPK) status, growth characteristics and yield of rice were examined by application of poultry manure (PM), cow manure (CM) and compost (CP). Organic fertilizers were applied as EMN (estimated mineralizable N) based on their total N content. Six treatments were assigned in a randomized complete block design: (1) no-N fertilizer (N0); (2) 50% CF (CF50), (3) 100% CF (CF100); 50% CF + 50% EMN from (4) PM or (5) CM or (6) CP. Compared with CF100, the CF50PM50 (total N ≥ 4%) accumulated higher N, P and K content in leaf, sheath, panicle and seeds, resulting in greater growth and yield. The CF50PM50 increased yield by 8.69% and 9.70%, dry matter by 4.76% and 5.27% over CF100 in both years. The continuous application of CF50CM50 (total N < 4%) and CF50CP50 (total N < 4...
A field experiment was conducted during the Kharif and Rabi seasons of 2001-2005 in regular crop sequence at Crop Research Station, Nawabganj, CSA University of Agriculture & Technology, Kanpur in order to find out the effect of farm yard manure (FYM) and NPK levels in rice-wheat-1-1 cropping system. One level of FYM (10 t ha) and one level of N (120 kg ha),three levels of P (0, 30,-1-1 60 kg ha), four levels of K (0, 30, 60, 90 kg ha) were tested. The grain yield of rice and wheat crops-1-1 were increased at levels of FYM (10 t ha) and NPK (120, 60, 60 kg h a). The application of FYM with 1 120 kg N, 60 kg P O and 60 kg K O ha-gave significantly highest yield of rice and wheat crops. The 2 5 2 application of NPK fertilizers with FYM were found increased in their uptake. The application of NPK fertilizers with FYM was found improvements in physio-chemical properties of soil like soil ph, organic carbon and available NPK.

In the year of 2017, a field experiment was conducted in kharif season, A2 Block of Norman E. Borlaug Crop Research Center (NEBCRC) of G.B.P.U.A&T. Pantnagar, Udham Singh Nagar, (Uttarakhand) to evaluate the influence of balance fertilizer application in a long term on yield and yield attributing characters of rice (Oryza sativa L.). These treatments were a part of long-term fertility experiment since 1984. Nine treatments out of fourteen consisting different combination of N, P, K, Znf and FYM were tested in a Randomized Block Design with four replications. The variety sown was HKR 47. In the present study addition or deletion of nutrient or nutrient sources in the recommended fertilizer dose responded in an almost similar way in affecting yield over the period of 33 years. Reduction in nutrients sources in recommended dose of fertilizer led to 33-50% reduction in yield while addition of FYM led to 7% increase in rice grain yield. The grain yield over 33 years of experimentation revealed that highest production (6.10 t ha-1) was obtained with the application of N120P40K40+Znf+FYMr which was statistically at par with N120P40K40+FYMr and N120P40K40+Znf. This could be due to the additional supply of N, P, K and Zn with FYM applied @ 5 t ha-1 since last many years that led to better fertility status resulting the good supply of nutrients. The increased yield of rice in FYM consisting treatment was however mainly due to increase in 1000-grain weight and of a lower number of unfilled spikelets compared to other treatments. The incomplete fertility treatments i.e. N120, N120K40 had resulted in the maximum number of unfilled grains and lowest total spikelets per mresults in yield reduction as compared to FYM added treatments. It suggested that FYM, that is known to add all type of nutrients in the soil and maintaining soil health in all respects i.e. biological, physical and chemical, was able to maintain the productivity and fertility status of soil over the years compared to a recommended dose of fertilizer in which 26% reduction was noticed.
Background Efficient and balanced fertilization is of paramount importance for both economic harvest and environmental aspects. Fertilizer use in Pakistan has been rising over the many years; however there is a stagnation in crop yields due to imbalanced use of fertilizers. Generally, growers are applying high quantity of nitrogen (N) but only small or sub-optimal amounts of phosphorus (P). Moreover, inter and intra specific variations exist in crop plants for their nutritional requirements based on their genetic and agronomic characteristics. Therefore, it is essential to formulate balance fertilizer dose primarily for newly evolved crop genotypes to get higher yields and to fetch maximum economic return to the farmers. Methodology A field trial was conducted at the experimental farm of Nuclear Institute of Agriculture (NIA) Tandojam, Pakistan to evaluate the effect of various N and P ratios on paddy yield and nutrient use efficiency of rice genotype (NIA-20/A). The study was planned in complete randomized block design (RCBD) with three replications. Three rates of N (90, 120, 150 kg ha

A pot culture experiment entitled "soil properties of medium land rice (Oryza sativa L.) in inorganic nitrogenous fertilizers on fym combination in yield." was conducted at Institute of Agricultural Sciences farm of Siksha "O" Anusandhan (Deemed to be University), Bhubaneswar Odisha on sandy loam soil during kharif 2018-2019. The experiment was planned in a Randomized Block Design with three replications and comprised eight treatment such as T1-Control, T2-50% Recommended dose of fertilizer (RDF),T3-50% RDF + 5t FYM per ha-1, T4-75% RDF, T5-75% RDF + 5t FYM per ha-1, T6-100%RDF (NPK 80:40:40), T7-100% RDF + 5t FYM per ha1and T8-150% RDF. Similar inclination were observed on yields of grain, straw and values of different growth parameters at different level of nitrogen and their combination with 5t FYM per ha-1 but at 150 % RDF level, the values of different parameters including grain and straw yield were significantly low as compared to the treatment that received 100% RDF + 5t FYM per ha-1. Grain and straw analysis recorded higher N, P, K content by use of 100% RDF + 5t FYM per ha-1 as compared with 100% and 150% RDF alone. physio-chemical conditions of soil like bulk density, porosity, organic carbon, available macro nutrients (N, P,K) were improved with the joint application of 100% RDF as inorganic source with 5t FYM per ha-1as organic source. In this present study it can be resolved that in Odisha soil (sandy loam) joint application of 100 % mineral nitrogen and 5t FYM per ha-1 enhanced availability of macro nutrients, better physical environment and produced significantly low yields with application of 150% RDF as compared to treatment combinations with inorganic fertilizer and FYM and almost equal yield with the recommended dose of nitrogen (100% RDF) only in mineral form.

Soil fertility, one of the important determinants of agricultural productivity, is generally thought to be supplemented through the application of nutrients mainly through inorganic fertilizers. The physical fertility of the soil, which creates suitable environment for the availability and uptake of these nutrients, is generally ignored. The present study aims to characterize the soil physical environment in relation to the long term application of farm yard manure (FYM) and inorganic fertilizers in rice–wheat. The treatments during both rice and wheat crops were (i) farm yard manure @ 20 t ha−1 (FYM); (ii) nitrogen @ 120 kg ha−1 (N120); (iii) nitrogen and phosphorus @ 120 and 30 kg ha−1 (N120P30) and (iv) nitrogen, phosphorus and potassium @ 120, 30 and 30 kg ha−1 (N120P30K30) in addition to (iv) control treatment, i.e. without any fertilizer and/or FYM addition. The treatments were replicated four times in randomized block design in a sandy loam (typic Ustipsament, non-saline, slightly alkaline). Bulk density, structural stability of soil aggregates and water holding capacity of 0–60 cm soil layer were measured.The average mean weight diameter (MWD) was highest in FYM-plots both in rice (0.237 mm) and wheat (0.249 mm) closely followed by that in N120P30K30 plots. The effect of FYM in increasing the MWD decreased with soil depth. The addition of both FYM and N120P30K30 increased the organic carbon by 44 and 37%, respectively in rice. The total porosity of soil increased with the application of both FYM and N120P30K30 from that in control plots. In 0–15 cm soil layer, the total porosity increased by 25% with FYM from that in control plots. This difference decreased to 13% in 15–30 cm soil layer. The average water holding capacity (WHC) was 16 and 11% higher with FYM and N120P30K30 application from that in control plots. The MWD, total porosity and WHC improved with the application of balanced application of fertilizers. The grain yield and uptake of N, P and K by both rice and wheat were higher with the application of FYM and inorganic fertilizers than in control plots. The carbon sequestration rate after 32 years was maximum (0.31 t ha−1 year−1) in FYM-plots, followed by 0.26 t ha−1 year−1 in N120P30K30-plots, 0.19 t ha−1 year−1 in N120P30 and minimum (0.13 t ha−1 year−1) in N120-plots.
