Prilled Urea

Field experiment was conducted to determine the effect of prilled urea (PU) and urea super granule (USG) with their different nitrogen levels (N1 : 70, N2 : 100 and N3 : 130% of the recommended dose) on rice and NH4+-N/NO3- -N in post-harvest soil. Experiment was laid out in a randomized completely block design with three replications at Bangladesh Institute of Nuclear Agriculture (BINA) Farm, Mymensingh, Bangladesh during 2015-16. Higher yield attributing characters (plant height, effective tiller panicle-1, panicle length were achieved from USG × N2 treatment. USG, N2 (100% N) and USG × N2 produced the highest grain (3.60, 3.64, 3.78 t ha-1) and straw yield (3.55, 3.45, 3.70 t ha-1) respectively. Though USG × N3 treatment produced the highest effective tiller, panicle length and unfilled grain but USG × N2 treatment produced maximum grain yield of rice due to higher filled grain. In respect of mineral nitrogen, NH4+-N was decreased with the increase in soil depth but opposite result was found in NO3- -N in soil. Deep placement of USG fertilizer released NH4+-N slowly and steadily compared to prilled urea in soil. As a result, one time fertilizer application of USG is better than three times broadcast application of PU in terms of crop yield, nitrogen status in different depth of soil and labour cost. Future research needs to develop the effective USG fertilizer applicator for deep placement in soil during crop production.

An experiment was conducted to evaluate the performance of deep placement of urea and NPK briquettes compared to broadcast application of prilled urea for bitter gourd production during the Kharif-1 season of 2013. The experiments were conducted in two locations in Jessore district, Chowgacha and Jessore sadar. Seven treatments were designed to evaluate crops response: T1: Control, T2: Farmer’s practice, T3: Recommended doses of all fertilizers except N, T4: Recommended doses of all fertilizers, T5: Urea briquette + other fertilizers, T6: NPK briquette + other fertilizers and T7: NPK briquette + other fertilizers except cowdung. The rate of urea and NPK briquette was 10 percent less than the rate of recommended prilled urea. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The sizes of NPK and urea briquette were 3.4 g and 2.7 g, respectively. The recommended fertilizer doses were used to supply N, P, K, S, Zn and B from Urea, TSP, MoP, gypsum, zinc sulphate (hepta) and boric acid, respectively. The results showed that deep placement of NPK briquette gave significantly the highest yield of bitter gourd (32.16 tha-1) followed by urea briquette (30.45 tha-1) which were 12.34 and 7.41 percent higher over recommended doses of all fertilizers. The highest N recovery (77.4 %) was found when 72 kg N ha-1 was applied as NPK briquette.J. Environ. Sci. & Natural Resources, 8(1): 157-160 2015

Rice (Oryza sativa L.) is the most important crops commodity in Indonesia because it is the main staple for the people of Indonesia but currently,  in Indonesia, the production of rice is still not maximal so it can not meet the demand of Indonesian people for national food needs. Therefore, it is necessary for rice plants that have high production and tolerant to various stresses. Plant breeding  is one of the ways that can be done to increase the production of rice, one of which is the method of cross-recurring selection. Genetic diversity is a variation of characteristics that are inherited in the same species population. This study aims to obtain information about genetic diversity and agro-morphological characters of 50 genotypes rice derived from the recurrent selection. This research was conducted from August until December 2017 in Rawa Makmur Village, Bengkulu Province with the height of place from sea level ± 2 m. The study used a Completely Randomized Block Design (RAK) with 3 replications. The seeds used were 50 genotypes of rice from previous cross-selection results from Bugis/N-22 crossbreeds, Bugis/IR-7858-1, Sriwijaya/N-148, Sriwijaya/IR-7858-1. The results showed that the genetic diversity of rice is quite narrow to moderate, but there are some rice characters that have medium to high heritability value that was plant height, harvesting age, flowering age, the total number of tillers and panicle length, so that character can be used for the next generation rice selection. The genotypes produced by Bugis/IR-7858-1 crosses have panicle length, filled grain per panicle, and high grain weight/hill resulting in high yield potential.

A field experiment was carried out in participatory mode on farmers’ field at Bhoimunda village of Jharsuguda block under Jharsuguda district, Odisha during Kharif season of 2017, 2018 and 2019 to study the efficiency of nutrient management along with green manuring crop on productivity, profitability and soil fertility of rice under Western Central Table Land Zone of Odisha, India. The adopted village was selected by Krishi Vigyan Kendra, Jharsuguda, Odisha under National Innovations in Climate Resilient Agriculture (NICRA) project. The experiment was laid out in Randomized Block Design with four treatments replicated five times taking rice (cv. Sahabhagi dhan) as test crop.  The treatments comprised of four viz. T1: Farmer’s practice (NPK @ 50:20:20 kg ha-1), T2: Recommended dose of fertilizer (NPK @ 60:30:30 kg ha-1), T3: 75% RDF + Green manuring of dhaincha  (Sesbania aculeata) with seed rate of @ 25 kg ha-1 and T4: Soil Test Based NPKZnB @ 75:38:30:6.25:1.25 kg ha-1 + Green manuring.  Results revealed that application of Soil Test Based NPKZnB @ 75:38:30:6.25:1.25 kg ha-1 along with green manuring producing dry biomass 5044 kg ha-1  (T4) recorded significantly higher growth and yield attributes, grain yield (4.04 t ha-1), straw yield (5.15 t ha-1), harvest index (43.92%) as well as nutrient uptake in grain and straw of the crop over farmers practice. The same treatment recorded significant improvement in soil pH, organic carbon, available macronutrients (N, P and K) and micronutrients (Zn and B) status of soil after harvest of the crop. The highest benefit: cost ratio (1.62) and returns (Rs. 28559 ha-1) were recorded with the same treatment (T4) over farmers practice. The present study showed that use of green manuring along with balance nutrition, is an important strategy to maintain and/or improve soil fertility for sustainable crop production in drought prone areas as well as remunerative rice production by the farmers in Odisha, India.

The page numbers of this article have changed from 68-78 to 71-81.BRRI prilled urea applicator was designed and developed to facilitate deep placement of regular urea. Experiments were conducted to evaluate the performance of BRRI prilled urea applicator in the farmers’ fields at Gosaidanga in Shailkupaupazila under Jhenaidah district and at Rashidpur in Mithapukurupazila under Rangpur district during Boro 2015 season. Three treatments: hand broadcasting of urea (recommended dose) (HB), BRRI prilled urea applicator (70% of the recommended dose) (PUA) and BRRI USG applicator (70% of the recommended dose) (USGA) were compared in the experiments. The experiment was laid out in randomized complete block design (RCBD) and replicated in four farmers’ plots in each location using BRRI dhan28 as test crop both the locations. Prior to field experiment, prilled urea applicator was calibrated and urea dispensed was set to 14 gm in one revolution of drive wheel for Boro season. The field capacity of the PUA and USGA was almost similar (0.09-0.10 ha hr-1) in both the locations. Field efficiency of PUA and USGA had 64-65 and 68-69 percent, respectively. PUA and USGA saved 29-32 percent urea fertilizer compared to HB whereas labour requirement of HB (3.74-4.04 man-hr ha-1) in three splits showed similar to single application of urea by PUA (3.68-4.00 man-hr ha-1) and USGA (3.78-3.97 man-hr ha-1). Urea application cost in HB, PUA and USGA was Tk 4,624, 3,216-3,424 and 3,305-3,483 per hectare in both the locations. Prilled urea application method reduced the production cost. Urea application methods showed insignificant effect on grain yield. BRRI prilled urea safely dispensed urea fertilizer in subsurface, increased the efficacy of urea fertilizer and saved urea fertilizer without sacrificing grain yield. BRRI prilled urea applicator could be a viable technology in rice cultivation. Extensive dissemination works should be undertaken in different agro-ecological zones for wide spread adoption of the applicator.Bangladesh Rice j. 2015, 19(2): 71-81

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during boro season of 2014 to evaluate the effect of deep placement of nitrogen (N) fertilizers on N use efficiency and yield of BRRI dhan29 under flooded condition. The soil was silt loam in texture having pH 6.27, organic matter content 1.95%, total N 0.136%, available P 3.16 ppm, exchangeable K 0.095 me%, available S 10.5 ppm and EC 348 ?S cm-1. The experiment was laid out in a Randomized Complete Block Design (RCBD) with eight treatments and three replications. The treatments were T1 [Control], T2 [Prilled urea (130 kg N ha-1)], T3 [USG, 130 kg N ha-1], T4 [USG, 104 kg N ha-1], T5 [USG, 78 kg N ha-1], T6 [NPK briquette, 129 kg N ha-1], T7 [NPK briquette, 102 kg N ha-1] and T8 [NPK briquette, 78 kg N ha-1]. All the treatments except T6, T7 and T8 received 25 kg P and 64 kg K ha-1 as TSP and MoP respectively. In T6, T7 and T8 treatments, P and K were supplied from NPK briquettes. Prilled urea was applied in three equal splits. USG and NPK briquettes were applied at 10 DAT and were placed at 8-10 cm depth within four hills at alternate row. After deep placement of USG and NPK briquette, and each split application of PU, the water samples were collected for 5 consecutive days and analyzed for NH4-N concentration in surface water. After application of N fertilizers, the NH4-N in floodwater reached peak on the 2nd day in PU treated plots and then decreased rapidly over time. In the USG and NPK briquette treated plots, the NH4-N was generated slowly but spontaneously over the entire growth period as compared to PU indicating a beneficial role of USG and NPK briquette. The highest grain yield of 7.16 t ha-1 was recorded for T6 [NPK briquette, 129 kg N ha-1] which was statistically similar to that of T3 [USG, 130 kg N ha-1] and T4 [USG, 104 kg N ha-1]. The highest straw yield of 8.05 t ha-1 was obtained for T3 [USG, 130 kg N ha-1]. The deep placement of USG and NPK briquettes enhanced the recovery of applied N and N use efficiency in comparison with the broadcast application of N fertilizers.Asian J. Med. Biol. Res.

Significant Difference

Herbicide-resistant weeds have prompted the development of non-chemical weed-control techniques for sustainable crop production. We examined the potential of pre-emergence microwave (MW) soil treatment to suppress weeds and enhance grain yield in rice (Oryza sativa L.) cropping in two agro-ecological zones of Australia. An experimental MW weed killer, which has four, independently controlled, 2-kW MW generators operating at 2.45 GHz, was used to treat the soil before cropping under field conditions. A once-off MW soil treatment (duration 60 s) and an untreated control were assigned in a randomised complete block design with five replicates at two study locations: Dookie (Victoria) and Jerilderie (New South Wales). Simpson’s numerical surface integral approximation estimated the applied energy density of ~500 J cm–2. This energy increased the soil’s temperature up to 70–75°C in top soil horizon (0–6 cm) as depicted by infrared thermal imaging. No statistically significant difference was detected for weed control between MW and untreated control plots at either study location. At Dookie, grain yield did not significantly increase in response to MW soil treatment, whereas at Jerilderie, grain yield was 20% higher (P < 0.05) with MW soil treatment than in control plots. At Jerilderie, the irrigation water use efficiency (t ML–1) was 21% higher in MW plots than control plots. In summary, MW exposure of 60 s appeared to be an insufficient heating duration for seedbank depletion. This suggests further treatment modification followed by rigorous testing under different soils conditions using the MW prototype.
