A field experiment was carried out during the rainy (kharif) season of 2001 at the experimental farm of the Indian Agricultural Research Institute, New Delhi, India, to study the effect of date of transplanting and nitrogen on yield attributes, yields, nutrient accumulation and nitrogen use efficiencies in hybrid and non-hybrid aromatic rice. The experiment consisted of 9 treatments with 2 varieties (Pusa Basmati 1 and Pusa Rice Hybrid 10), 3 transplanting dates (3, 10 and 17 July, 2001) and 4 nitrogen levels (0, 60, 120 and 180 kg N ha-1). Pusa Rice Hybrid 10 had significantly higher values of yield attributes (panicles hill-1, panicle weight, spikelets panicle-1, filled grains panicle-1, 1000-grain weight), yields and nutrient accumulation than the non-hybrid Pusa Basmati 1. There were significant reductions in yield attributes, yields and nutrient accumulation after delayed transplanting. Timely transplanting on 3 July led to 8.4 and 19.1% higher grain yield than transplanting on 10 and 17 July, respectively. Successive nitrogen levels had a significant effect on yield attributes (except 1000-grain weight), yields and nutrient accumulation up to 120 kg N ha-1. The maximum grain yield (5.87 t ha-1) was recorded at the highest level of N nutrition (180 kg Nha-1) and was 4.2, 15.5 and 39.3% higher than in the 120 kg, 60 kg N ha-1 and control treatments, respectively. Pusa Rice Hybrid 10 also had significantly higher values of agronomic nitrogen use efficiency (ANUE) (12.5 kg grain kg-1 N applied), apparent nitrogen recovery (27.4%), physiological NUE (44.2 kg grain kg-1 N uptake), N harvest index (62.7%), N efficiency ratio (119.6 kg dry matter kg-1 N uptake) and physiological efficiency index of nitrogen (47.4 kg grain kg-1 N uptake) than non-hybrid Pusa Basmati 1.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during November 2014 to April 2015 to investigate the effect of planting spacing and nitrogen levels on yield attributes and yield of maize cv. Khaibhutta. The experiment comprised three nitrogen levels viz. 50, 100 and 150 kg N ha-1 and five plant spacings viz. 75 cm × 25 cm, 75 cm × 20 cm, 50 cm × 25 cm, 50 cm × 20 cm and 100 cm × 20 cm. The experiment was laid out in a randomized complete block design with three replications. Results revealed that nitrogen levels and plant spacing had significant effect on yield attributes and yield of Khaibhutta. The highest number of cobs plant-1, grains row-1, grain yield and stover yield were recorded with 150 kg N ha-1 followed by 100 kg N ha- 1and the lowest values were observed in 50 kg N ha-1. The highest number of cobs plant-1, grain rows cob-1, grains row-1, grains cob-1, 1000-grain weight, grain yield and harvest index were recorded at 75 cm × 25 cm spacing. In contrast, the closest spacing of 50 cm x 20 cm produced the lowest values of grain rows cob-1, grains row-1, grains cob-1, 1000-grain weight and grain yield. In case of interaction, the highest grain yield and harvest index were obtained at 75 cm × 25 cm spacing fertilized with 150 kg N ha-1. The lowest values of the above parameters were recorded in the closest spacing 50 cm × 20 cm with 50 kg N ha-1. From this study it may be concluded that maize (cv. Khaibhutta) can be cultivated at the spacing of 75 cm × 25 cm with 150 kg N ha-1 for appreciable grain yield.J. Bangladesh Agril. Univ. 14(1): 43-48, June 2016

Weeds are major threat to global wheat production and cause serious threat to food security. Likewise, water scarcity is also a major threat to food production and its intensity is continuously soaring up across the globe. Organic mulches have potential to reduce weeds growth and conserve the soil moisture thus ensures the better crop growth and yield. Therefore, present study was conducted to compare the performance of different organic mulches in improving wheat growth and productivity. The study was comprised of different organic mulches; M1= No mulch (control) M2= maize straw mulch, M3= wheat straw mulch, M4= sorghum straw mulch and M5= rice straw mulch and three nitrogen levels N1 = 90 kg, N2 = 120 kg and N3= 150 kg/ha. The results indicated that both organic mulches and N rates had significant impact on growth, and yield traits. The maximum leaf area index (LAI), crop growth rate (CGR), productive tillers (307 m-2), grains/spike (46.22), 1000 grain weight (42.33 g) biological yield (13.76 t/ha) and grain yield 4.75 t/ha was obtained with sorghum straw mulch and minimum productive tillers (255.33 m-2), grains/spike (36.22), biological yield (11.46 t/ha) and grain yield (3.59 t/ha) was recorded in no mulch (control). Among nitrogen levels maximum productive tillers (290.6 m-2), grains/spike (42.80), 1000 grain weight (40.65 g), biological yield (13.44 t/ha) and grain yield (4.32 t/ha) was obtained with 150 kg/ha N and minimum productive tillers (274 m-2), grains/spike (38.13), 1000 grain weight (36.94 g) biological yield (11.98 t/ha) and grain yield (3.90 t/ha) was obtained with 90 N kg/ha. Thus, farmers can use sorghum straw mulch and N (150 kg ha-1) to improve the wheat productivity. However, farmers must be educated by government institute and adoptive research farms in order to understand and adaption of this approach.

An experiment was conducted at the Agronomy Field of Patuakhali Science and Technology University, Dumki, Patuakhali from June to December, 2013 to find out the effect of variety and planting density on the yield and yield attributing characters of local aromatic rice. The experiment was laid out in a factorial randomized complete block design with three replications, which consisted of three local aromatic rice varieties (Chinigura, Shakhorkhora and Kalizira) and four planting densities were viz. S1 (25 cm × 20 cm), S2 (20 cm × 20 cm), S3 (20 cm × 15 cm) and S4 (20 cm × 10 cm). The results revealed that the local aromatic rice var. Shakhorkhora variety produced the highest number of grains per panicle (131) and 1000-grain weight (13.8 g), consequently higher grain (2.63 t ha-1), followed by Kalizira (2.56 t ha-1) and straw yield (4.21 t ha-1). One the other hand, higher number of tillers per hill (14.8), number of grains per panicle (140 nos.) were found in 20 cm × 20 cm spacing with higher grain yield.Bangladesh J. Agril.

A Factorial experiment were conducted at the experimental  farm of Field Crop College of Agriculture University of Baghdad Jadiria the winter Season of 2014-2015. This study was aimed to investigate the effect of seeding rates and nitrogen levels on Regulation of tillering in wheat and  its relationship with grain yield and it's components. Treatments were distributed in Factorial experiment within Randomized Complete Black Design (RCBD) with three replicates and with four seeding  rates (60,80,100 and 120 kg.ha-1) and fertilized with four nitrogen levels (50,100,150 and 200 kgN.ha-1). The results showed that there were significant differences between two factors of study and their interaction on the number of spiklet, grain number and 1000 grain weight during the growing season. Main stem produced the highest average of spiklet number 19.23 spiklet.spike-1, grain number 46.82 grain.spike-1 and 1000 grain weight 41.739 compared to other primary tillers (tiller1,tiller2,tiller3). Concerning the seeding rate 60 kg.ha-1 resulted in the highest average of spiklet number 16.24 spiklet.spike-1, grain number 32.95 grain.spike-1 and 1000 grain weight 27.52 compared to other seed rates. The N level 100 kg.ha-1 gave the highest average of spiklet number 16.49 spiklet.spike-1, grain number 32.95 grain.spike-1 and 1000 grain weight 27.52 compared to other N levels. The Main Stem and Primary Tillers contribution Differed in the Number of Spiklet, Grain Number and 1000 grain weight between the factors of study, where the percentage contribution of main stem 31.65, 38.26 and 37.28 % respectively compared to the tillers (tiller1, tiller2, tiller3) which amounted to 27.43, 24.79 and 16.14 % respectively in the spiklets number, 28.00, 23.36 and 10.38 % respectively in grains number and 31.80, 20.37 and 10.56 % respectively in 1000 grain weight. We conclude that the total contribution of the primary tillers percentages in the Number of Spiklet, Grain Number and 1000 grain weight Exceeds the contribution of main stem an increase of 53.69 and 38.03 and 40.56 % respectively within two factors of study.

An experiment was conducted during July-December 2001 at the Agronomy field laboratory, Bangladesh Agricultural University, Mymensingh to study the effect of nitrogen levels and plant spacing on the yield and yield contributing characters of transplant Aman rice (var. BRRI Dhan 31). Five levels of nitrogen (0, 50, 100, 150, 200 kg N/ha) and three spacings (25 cm x 20 cm, 25 cm x 15 cm, 25 cm x 10 cm) were included as treatment variables. A gradual increase in panicle length (24.50 cm), grains/panicle 110) and grain yield (4.91 t/ha) were observed with the increase in nitrogen levels upto 150 kg/ha and declined thereafter. Thousand-grain weight was not significantly influenced by application of different levels of nitrogen. The maximum grain yield (4.22 t/ha) was observed at the spacing 25 cm x 10 cm closely followed by 25 cm x 15 cm (4.21 t/ha). Wider spacing (25 cm x 10 cm) produced the tallest plant (108.38 cm), but significantly highest tllers/hill (8.06) and grains/panicle was recorded from (25 cm x 20 cm). Plant spacing had also no significant effect on 1000-grain weight. The interaction effects of nitrogen and plant spacing was significant in panicle length, grains/panicle, and grain yield. The higher grain yield (5.00 t/ha) was recorded from the treatment combination of 150 kg N/ha with 25 cm x 15 cm spacing, but statistically identical to same N dose with other two spacings. Response of grain yield to added N was quadratic. The optimum doses were found to be 132 kg N/ha for 25 cm x 20 cm, 119 kg N/ha for 25 cm, and 177 kg N/ha for 25 cm x 10 cm spacing, yielding 4.38, 4.63 and 4.75 t/ha, respectively.

Yield potential of 16 rice genotypes including 12 hybrids, 3 inbreds, and I new plant type (NPT), were studied at the International Rice Research Institute farm under optimum crop management to achieve maximum attainable yields during the wet season (WS) of 2004 and dry season (DS) of 2005. Yield and yield components were determined at maturity. 1R76712H produced the highest grain yield (7.7 t/ha) followed by 1R75217H and Magat (7.6 t/ha) in WS; in DS, 1R79118H produced the highest grain yield (9.17 t/ha) followed by 1R73855H (8.9 t/ha) and SL-8H (8.8 t/ha. The high yield of hybrid rice was due to high harvest index (0.50). Hybrid produced significantly higher productivity (80.2 kg/ha/day) than inbred in DS, but the difference was not significant in WS. Hybrid produced higher spikelets/panicle and 1000-grain weight than inbred rice. Spikelet filling percent was higher in inbred than hybrid rice. The NPT rice genotype had the lowest spikelet filling percent, but the highest 1000-grain weight across the season. Keywords: Yield; yield attributes; hybrid and inbred rice genotypes.

The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.

A study on genetic variability, heritability and genetic advance for seed yield and component traits was made in 40 genotypes of riceduring kharif 2011-2012 at SHIATS, Allahabad. The analysis of variance showed highly significant differences among the treatments for all the 13 traits under study.The genotypes namely CN 1446-5-8-17-1-MLD4 and CR 2706 recorded highest mean performance for panicles per hill and grain yield. The highest genotypic and phenotypic variances (VG and VP) were recorded for spikelets per panicle (3595.78 and 3642.41) followed by biological yield (355.72 and 360.62) and plant height (231.48 and 234.35).High heritability (broad sense) coupled with high genetic advance was observed for plant height, flag leaf length, panicles per hill, tillers per hill, days to maturity, spikelet’s per panicle, biological yield, harvest index, 1000 grain weight and grain yield, indicating that selection will be effective based on these traits because they were under the influence of additive and additive x additive type of gene action. Highest coefficient of variation (PCV and GCV) was recorded for tillers per hill (18.42% and 17.23%), panicle per hill (19.76 % and 18.68%), spikelet’s per panicle (34.30 and34.07 %), biological yield (28.31 % and 28.12 %), 1000 grain weight (15.57 % and 15 31 %) and grain yield (46.66% and 23.54 %), indicating that these traits are under the major influence of genetic control, therefore the above mentioned traits contributed maximum to higher grain yield compared to other traits, indicating grain yield improvement through the associated traits.

Nitrogen use efficiency (NUE) is a necessitate in order to enhance sustainable rice farming in Indonesia. Thus, objective of present research was to evaluate NUE of local and national Indonesian superior aromatic rice treated with different levels of nitrogen fertilizer (N). Planting plot was arranged using five levels of N as the main plot, i.e; 0, 45, 90, 135 and 180 kg ha-1; and two rice varieties as subplot, i.e: Sigupai Abdya (local) and Inpari 23 Bantul (national). The results showed application 180 kg N ha-1 to Sigupai  Abdya significantly increased the plant height. However, it also postponed the flowering time. Inpari 23 Bantul treated with 180 kg N ha-1 produced the highest number of tillers. Combination of 90 kg N ha-1 with Sigupai Abdya variety significantly reduced the number of empty grains. Sigupai Abdya variety has a higher number of grains per panicle and sampling plot yield than Inpari 23 Bantul, and  dosage 90 kg N ha-1 increases grain yield per clump also sampling plot yield significantly. Nitrogen at 180 kg N ha-1 made Sigupai Abdya variety has high N content and absorption N in primordia phase, and the Inpari 23 Bantul variety had grain with high N content. Nitrogen at 90 kg ha-1 caused Sigupai Abdya variety at primordia phase had NUE higher than Inpari 23 Bantul. This study showed that local variety Sigupai Abdya is suitable for development as rice with low input NKeywords: Aceh aromatic, low input, nitrogen dose, N uptake, Oryza sativa L.
