A field experiment was conducted on farmer’s field at two sites of Lamjung district of Nepal viz. Bhotewodar and Sundarbazaar to evaluate the performance of two commonly grown rice varieties viz US-382(hybrid) and Ramdhan (improved) under two nutrient management practices [Nutrient Expert®(NE) rice model recommendation, and government recommendation(GR)].Four replicates of four treatments were arranged in randomized completely block design. Rice varieties responded differently under the different nutrient management practices in terms of plant height, grains per panicle, sterility%, panicle weight, grain yield at 15% moisture, straw yield and harvesting index. The highest grain yield was obtained from NE field of US-382 variety which was followed by GR for US-382, NE for Ramdhan and GR for Ramdhan variety. NE based practices for US-382 variety produced higher biological yield as compared to GR. NE estimated attainable rice yield provided by the software compared with actual rice yield from the trials in farmer’s field and NE-based fertilizer recommendations proved the validity in reaching the yield targets estimated by the software. The observed rice yields recorded in the trials were higher than the NE estimated attainable yields, so NE recommendation for US-382 variety was found better over GR.Int J Appl Sci Biotechnol, Vol 4(2): 223-227

Rice is an important world leading cereal crop grown extensively in tropical and sub-tropical regions of the world. However, its productivity is constrained by a number of problems. Currently, cereal yields are only 40 to 65% of their potential, mostly because nutrient management does not consider crop’s dynamic response to the environment and site specific nutrition management. Therefore, a field experiment was conducted on farmer’s field at Lamjung, Sundarbazar and Bhoteodar using Nutrient Expert® rice model from July 2015 to November 2015. Four replications of 5 treatments were arranged in randomized complete block design. Five treatments were Nutrient Expert recommendation (NE hybrid), Government recommendation (GR hybrid), NE improved, GR improved and Farmers field practice (FFP). The result revealed significant difference in terms of plant height, panicle weight, filled grain/panicle, straw yield, grain yield at 15.5% moisture, biological yield and sterility %.The highest yield (7.362tonha-1) was obtained from NE hybrid field which was followed by GR hybrid (6.12tonha-1), NE improved (5.20tonha-1), FFP (4.76tonha-1) and GR improved (4.70tonha-1). While comparing Nutrient Expert® (NE) estimation for attainable rice yield with actual rice yield from the farmer field trial; NE-based fertilizer recommendations proved to be successful in reaching the yield targets estimated by the software. The actual rice yields recorded in farmer fields were higher than the NE estimated attainable yields, so NE recommendation was found better over GR and FFP. Int J Appl Sci Biotechnol, Vol 4(2): 178-182

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh to investigate the influence of plant nutrient management on the yield performance of transplant Aman rice. The experiment comprised two Aman rice varieties viz. Binadhan-15 and Binadhan-16, and ten nutrient management viz. Recommended dose of inorganic fertilizer (RDF) Urea-TSP-MoP-Gypsum-ZnSO4 @ 150-110-70-60-5 kg ha-1, Cowdung @ 10 t ha-1, Poultry manure @ 5 t ha-1, Vermicompost @ 3 t ha-1 , 25% less than RDF + cowdung @ 5 t ha-1, 50% less than RDF + cowdung @ 10 t ha-1 , 25% less than RDF + poultry manure @ 2.5 t ha-1, 50% less than RDF + poultry manure @ 5 t ha-1, 25% less than RDF + vermicompost @ 1.5 t ha-1, 50% less than RDF + vermicompost @ 3 t ha-1. The experiment was laid out in a randomized complete block design with three replications. Binadhan-15 produced taller plants (97.86 cm), effective tillers hill-1 (6.28), grains panicle-1 (101.73), higher grain (3.58 t ha-1) and straw (4.99 t ha-1) yields compared to Binadhan-16. In case of nutrient management, 50% less than RDF + poultry manure @ 5 t ha-1 produced taller plants (101.1 cm), effective tillers hill-1 (7.07), grains panicle-1 (105.1) and grain yield (4.08 t ha-1). The highest grain yield (4.25 t ha-1) was recorded in Binadhan-15 fertilized with 50% less than RDF + poultry manure @ 5 t ha-1 and the lowest grain yield (2.28 t ha-1) was obtained in Binadhan-16 fertilized with vermicompost @ 3 t ha-1. So, it can be concluded that transplant Aman rice cv. Binadhan-15 fertilized with 50% less than RDF + poultry manure @ 5 t ha-1 appears as the promising practice to obtain the highest grain yield.

ABSTRACT The upland rice farmers in Suriname use local varieties and low level technologies in the field. As a result, the upland rice grain yield is low, at about 1 000 kg ha-1. Our objective was to evaluate the use of upland rice cultivars from Suriname and Brazil, and the effect of nitrogen, N, phosphorus, P, and potassium, K, fertilizers on cultivation variables. We undertook four field trials in the Victoria Area, in the Brokopondo District, using a randomized block design each with four replications. The most productive rice varieties were BRS Esmeralda (grain yield 2 903 kg ha-1) and BRS Sertaneja (2 802 kg ha-1). The highest grain yield of 2 620 kg ha-1 was achieved with a top dressing application of 76.41 kg N ha-1 20 days after sowing. For P, the highest grain yield of 3 085 kg ha-1 was achieved with application of 98.06 kg ha-1 P2O5 applied at sowing. An application rate of 31.45 kg ha-1 of K2O at sowing achieved the highest grain yield of 2 952 kg ha-1. Together, these application rates of N, P and K resulted in rice grain yield of about 3 000 kg ha-1, which is three times greater than the national average for upland rice. We demonstrate that the use of improved rice varieties matched to the local conditions, and application of appropriate fertilizers, are management practices that can result in significant increases in rice grain yield in Suriname.

The Field experiment was conducted to evaluate the effect of fertility management on growth, yield attributes and yield of pearlmillet in a Randomized Block Design (RBD) with ten treatments and four replications during summer, 2019 at Anand, Gujarat. The experiment comprises of different nutrient management practices including 100% and 75% RDF with 15 t and 10 t FYM along with Bio NP consortia. A significant higher growth and yield parameters enhancement with the application of 100% RDF + 15 t FYM ha-1 + Bio NP Consortia was recorded in plant height, number of tillers, length of ear head, protein content and biological yield. The treatment T5 produced maximum (91.5 q ha-1) biological yield and statistically it was on par with T9 and T5. However, the lowest biomass production (73.0 q ha-1) was reported in treatment T1. Results of different nutrient management practices on days to 50% flowering, days to maturity, ear head girth and test weight were found non-significant.  Protein content of pearlmillet was increased from 7.5% to 9.06% under different nutrient management practices.

Evaluation of Specific Location Fertilizer Recommendations and Plant System on Rice Yield Temega Village, Abang District, Karangasem. This study aims to determine the response of specific location fertilizer recommendations and planting system on rice yields in Temega Village, Abang District, Karangasem Regency. The method was used Factorial Randomized Block Design (RBD). The treatment tried consisted of two factors. The first factor was fertilization recommendations (R): R1 = location specific recommendation (250 kg Urea/ha, 100 SP36/ha and 50 kg KCl/ha); R2 = Location specific recommendation + Compost (230 kg Urea/ha, 100 SP36/ha, 50 kg KCl/ha + 5 t compost/ha), R3 = Farmer method (300 kg Urea/ha, 125 SP36/ha and 75 kg KCl/ha). The second factor was planting system (TL) : T = Tegel (20 cm x 20 cm) and L = Jajar Legowo 2 : 1. Combination of treatments into 6 treatments and each treatment was replicated 4 times so that there were 24 plots of research. The results showed that location specific fertilizer recommendations resulted in oven dry grain weight m-2 of 0.84 kg compare to that of farmers (0.85 kg). The application of location specific fertilizer recommendations can save as much as 50 kg Urea/ha, 25 kg SP36/ha and 25 kg KCl/ha. Jajar Legowo planting system can produce grain contain m-2 of 1.14 kg or an increase of 78.13% compared to tegel planting system (0.64 kg).

Foxtail millet is an indigenous crop known for its rich nutritive value, drought tolerance ability and low input requirements. Though it is grown in marginal condition, it can give the best production with the proper nutrient management for its cultivation. In this respect, an experiment was conducted in Agronomy farm of Lamjung Campus, Sundarbazar during March-June 2017. The main objective of the experiment was to explore the performance of local foxtail millet under different level of nutrients. The experiment was carried out in Randomized Complete Block Design with three replications and seven treatments viz. FYM 6 t/ha, FYM 6 t/ha+60:30:20 kg NPK/ha, 60:30:20 kg NPK/ha, FYM 6t/ha+30:20kg PK/ha, FYM 6t/ha+60:30 kg NK/ha, FYM 6 t/ha+60:30 kg NP/ha and Control (no fertilizers). Results revealed that highest grain yield (2.47t/ha) (152% higher than control), was obtained from FYM 6 t/ha+60:30:20 kg NPK/ha which was followed by 60:30:20 kg NPK/ha (2.45 t/ha) and were statistically at par with each other. The highest grain yield in FYM 6 t/ha+60:30:20 kg NPK/ha was supported by higher no. of grains per panicle (2870), more test weight (1.79 gm) and more harvest index (19.3%). However, the straw yield (12.6t/ha), biological yield (15.02t/ha) along with B: C ratio was found slightly higher in 60:30:20 kg NPK/ha. The growth characters viz. plant height, flag leaf area and panicle length of all the treatments were significantly higher than Control (T7). The treatment having balanced plant nutrients (T2) produced significantly higher yield and can be recommended to mid-hill farmers for obtaining good yield.

A field experiment was carried out to study the effect of weed management practices on the performance of transplanted aman rice varieties. The experimental treatments comprised three varieties viz. BR11, BRRI dhan39 and Binadhan7 and seven weeding treatments viz., weedy check, hand weeding at 15 and 35 DATs, application of early post-emergence herbicide Manage (Pyrazosulfuron ethyl), application of pre-emergence herbicide Rifit (Pretilachlor), Manage + one hand weeding at 35 DAT, application of Rifit + one hand weeding at 35 DAT and weed free. The experiment was laid out in a randomized complete block design with three replications. The results reveal that varieties should significant variation on plant height, number of total tillers hill-1, number of effective tillers hill-1, number of non-effective tillers hill-1, panicle length, number of grains panicle-1, number of sterile spikelets penicle-1, 1000-grain weight, grain yield, straw yield and harvest index. Grain yield was the highest in BRRI dhan39. Weeding regime had also significant effect on all the studied crop parameters except 1000-grain weight. The highest grain yield was obtained from weed free condition followed by hand weeding at 15 and 35 DATs. Interaction between variety and weeding regime had significant influence on all the studied crop parameters except 1000-grain weight. The highest grain yield was obtained from the interaction of BRRI dhan39 × weed free condition which was statistically identical (5.50 t ha-1) with interaction of variety BR11 × two hand weedings at 15 and 35 DATs. Therefore it may be concluded that BR11 rice could be cultivated using two hand weedings at 15 and 35 DATs for obtaining higher yield.J. Bangladesh Agril. Univ. 14(1): 17-22, June 2016

Rice production has been inconsistent in Mwea irrigation scheme due to poor crop management practices and reduced soil fertility. Proper rice nutrition conserves the environment, increases sustained crop production, farmer’s crop yield and profits. A field experiment was conducted at MIAD Center, in Kirinyaga County, during 2016-17 and 2017- 18 to determine the response of rice varieties to different N, P and K fertilizer treatments. The trial was conducted in randomized complete block design, with three replications of 13 N, P and K fertilizer regimes as the main plots treatments and varieties Basmati 370 and BW 196 as the sub-plot treatment. The N kg ha-1: P2O5 kg ha-1: K2O kg ha-1 fertilizer treatment ratios used were: 00:00:00, 60:40:40, 80:60:60, 100:80:80, 60:40:00, 80:60:00, 100:80:00, 60:00:40, 80:00:60, 100:00:80, 00:40:40, 00:60:60 and 00:80:80. Plant height, number of tillers hill-1, panicle length, and grain yield responded positively to fertilizer application, but 1000-grain weight did not. Variety BW 196 recording shorter plants and panicles, more tillers hill-1, higher grain weight and yield than variety Basmati 370. 00:40:40, 00:60:60, 00:80:80, 60:40:00 and the no-fertilizer control treatments recorded the least number of tillers hill-1. 60:40:40, 80:60:60, 100:80:80, fertilizer treatments had longer panicles than the no fertilizer control and 00:40:40. Except for 100:80:00 and 00:40:40, in the first season and 60:40:00, 80:60:00, 100:80:00 in the second season, all the fertilizer regimes increased grain yield relative to the control. The highest grain yield was realized in fertilizer regime 80:60:60, 100:80:80, 80:00:60 and 100:00:80. 80:00:60 is the recommended fertilizer regime. Int. J. Agril. Res.

The use of sprinkler irrigation for rice (Oryza sativa L.) crop is a relatively recent practice in Brazil. Therefore, crop soil and fertilization management are still not very well defined. Another problem is the inexistence of specific cultivars adapted to this cropping system. This study aimed to evaluate sprinkler-irrigated upland rice cultivars under different soil management practices and nitrogen sidedressing rates in relation to yield and grain quality. A randomized block design was used, arranged as a 3 x 3 x 5 factorial scheme, totaling 45 treatments consisting of the combination of three rice cultivars (Primavera, Confiança and Maravilha), three soil management systems (disk harrow + levelling harrow, moldboard plow + levelling harrow and no-till) and five nitrogen rates, applied as sidedressing (0, 25, 50, 75 and 100 kg ha-1), with four replicates. The experiment was set up during the 1999/2000 and 2000/2001 cropping seasons, in Selvíria, MS, Brazil, on a Typic Haplustox of clayey texture. Cultivars Primavera and Maravilha presented higher grain yield than Confiança; on the other hand the latter showed higher milled and head rice yields during seed processing. Soil tillage with the moldboard plow and no-till interfered positively in the agronomic and productive characteristics of the crop. In relation to milled rice yield, tilling with the levelling disk + moldboard plow showed better results in relation to no-till. Nitrogen sidedressing did not interfere with the agronomic and productive characteristcs as well as with the milled rice yield of all cultivars.

The study was conducted in two locations of coastal districts Patuakhali and Satkhira during 2012 and 2013 T. Aman season. Stress tolerant rice varieties along with nitrogen application using prilled urea (PU), leaf color chart (LCC), urea super granule (USG), and rice crop manager (RCM) software based nitrogen (N) dose were examined. The objectives of the study were to identify the response of saline tolerant varieties to N fertilization on grain yield and profitability. Among the tested varieties, grain yield of BRRI dhan40, BRRI dhan41 and BRRI dhan54 were higher compared to BRRI dhan52 and BRRI dhan53 irrespective of location. There were no significant difference among the better performed varieties. Interaction effect of yield was significant in 2013 at Patuakhali but insignificant in both the locations in 2012. During 2013 in Patuakhali, the interaction effect of BRRI dhan40 × USG and BRRI dhan41 × USG produced higher grain yield and total N uptake. In Satkhira BRRI dhan54 and BRRI dhan40 performed better and produced higher grain yield and N uptake. Among the N application treatments USG application was the best compared to either LCC or RCM. The combination of BRRI dhan54×USG and BRRI dhan41×USG had more economic gains in both 2012 and 2013 in Patuakhali. The combination of BRRI dhan52×USG and BRRI dhan41×LCC appeared as themost profitable in Satkhira during 2013. Integration of saline tolerant varieties along with USG application could improve the yield of saline tolerant rice in saline environmentBangladesh Rice j. 2017, 21(1): 77-89
