A field experiment was conducted at Chandipur of Keraniganj Upazilla in the district of Dhaka, Bangladesh to screen out the studied rice varieties of BR 3, BRRI dhan 28, Local BRRI dhan 29, and BRRI dhan 74 as influenced by the Rice Straw Compost – RSC, Mustard Meal – MM, and Trichocompost – TC (indigenous organic amendments), and elevated soil temperature of 3°C in relation to the growth and yield response of rice. The experiment was conducted using split plot design with elevated temperature in main plots and the different rates of organic amendments in subplots. The rates of organic amendments were 0. 4, 8 t ha-1 for RSC; 0, 3, 6 t ha-1 for MM; and 0, 2.5, 5 t ha-1 for TC. The soil temperature was raised by 3°C from the daily field temperature of 22-25°C. Grain and straw yields, 1000-grain weight, number of filled and fissured grains of rice were significantly (p≤0.05) enhanced with the increased rates of RSC, MM, and TC at elevated temperature of 3°C.The maximum grain (8.86 t ha-1) and straw (8.40 t ha-1) yields were recorded in the treatment RSC4HW26-28 and RSC8HW26-28, respectively in BRRI dhan 29 over control, which endorsed the lowest grain (3.42 t ha-1) and straw (2.68 t ha-1) yields. The RSC treatment was ranked first in order of the growth-yield and yield components (1000 – grain weight and No. of filled and fissured grain) of rice followed by MM and TC treatments. The aforesaid treatments were found to have significantly (p≤0.05) positive aftermath with the elevated soil temperature, regardless of rice varieties. Increased rice production by the elevated soil temperature might be due to the CO2 fertilization, which is a very important climatic issue at present day environment. Bangladesh J. Sci. Ind.

A field study was conducted to determine the potentials of moist (70% soil moisture) and saturated (> 100% soil moisture) soil conditions and organic amendments of rice straw compost (RSC), mustard meal (MM) and trichocompost (TC) on the selected rice varieties of BR 3, local BRRI dhan 29 and BRRI dhan 74 in relation to the growth and yield attributes of rice varieties. The rates of amendments were 0, 4, 8 t/ha for RSC; 0, 3, 6 t/ha for MM and 0, 2.5, 5 t/ha for TC. The maximum grain yield of 8.71 t/ha was attained from the RSC4ML100 and 8.58 t/ha from RSC4ML70 treatments. The moist condition of soil had almost similar effects on the number of productive tillers, grain yield, number of filled and fissured grains, 1000-grain weight and harvest index as compared to saturated condition along with the doses of RSC, MM and TC. The RSC (4 t/ha) was the superior treatment with respect to the growth and yield components of rice followed by the treatments of TC (2.5 t/ha) and MM (3 t/ha), irrespective of rice varieties and moisture levels.

Abstract Ionizing radiation has extensive applications in agriculture for inducing mutagenic changes in major field crops, potential breeding purposes, varietal development and crop improvement. This study was conducted to test the efficacy of 0.8, 1.6, 2.4 and 3.6 kGy gamma irradiation doses (Cobalt-60) upon growth and yield performance of edible pea (Pisum sativum L.) in pot culture experiment during 2009. Results demonstrated that higher radiation doses (1.6 and 3.2 kGy) significantly influenced the studied attributes of P. sativum. It was observed that 3.2 kGy had detrimental effects on shoot and pod lengths of pea which were reduced by 14.60 and 17.71 % respectively when compared to control. Differential response of the number of seeds pod−1, 1000 grain weight and dry biomass of pea were recorded at the applied doses. Significant reduction in number of seeds (−14.21 %) but increase in 1000 grain weight (+13.93 %) and dry biomass (+11.32 %) of pea were recorded at 1.6 kGy which revealed stimulatory effects on grain weight and dry biomass. Conversely, radiation dose 3.2 kGy was found detrimental to all the studied parameters except number of pods plant−1 and number of seeds pod−1 which were not affected.

A pot culture and a field experiment were conducted with cyanobacteria in presence and absence of different levels of urea to evaluate their effects on growth and yield of rice cv. BRRI Dhan 28, 29 and 36 during Boro season of 2007. The treatments were T1 (control), T2 (only cyanobacteria), T3 (recommended doses of urea - 60 kg N/ha), T4 (45% recommended doses of urea + cyanobacteria), T5 (65% recommended doses of urea + cyanobacteria) and T6 (85% recommended doses of urea + cyanobacteria).The maximum values for different growth, yield and yield components (plant height, number of productive tillers/hill, panicle length, number of grains/panicle, 1000-grain weight, and grain, straw and biological yield) were observed in BRRI Dhan 29 under T6 (85% recommended doses of urea + cyanobacteria) and lowest was observed in BRRI Dhan 28 under T1 (neither urea nor cyanobacteria). Uses of cyanobacteria increased the yield of Boro rice varieties and decreased the use of urea by 15-20%.

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.

The effect of CCC on the growth of wheat in South Australia was assessed in three years, 1967 to 1969. A significant grain yield response was obtained only in the wet year, 1968, and was attributed to increased grain weight. It is suggested that the delay in heading and leaf senescence which occurred in CCC-treated plants allowed a greater assimilation of water and nutrients, thus producing the heavier grains. The lack of response in grain yield in 1967 and 1969 was probably due to moisture stress during gram filling. CCC reduced crop height significantly in 1968 and 1969, but not in the very dry year, 1967. There was evidence that split applications would be more useful than the single applications used in these experiments. Although CCC can give small increases in yield under some conditions, it is unlikely to be of commercial importance for wheat-growing in South Australia.

Pot experiments were conducted during T. aman 2001 and 2002 (wet season) at Bangladesh Rice Research Institute (BRRI) in net house. Hybrid variety Sonarbangla-1 and inbred modern variety BRRI dhan-31 were used in both the seasons and BRRI hybrid dhan-l was used in 2002. The main objective of the experiments was to compare the growth and yield behaviour of hybrid and inbred rice varieties under controlled condition. In 2001, BRRI dhan-3l had about 10-15% higher plant height, very similar tillers/plant, 15-25% higher leaf area at all days after transplanting (DAT) compared to Sonarbangla-1. Sonarbangla- 1 had about 40% higher dry matter production at 25 DAT but had very similar dry matter production at 50 and 75 DAT, 4-11% higher rooting depth at all DATs, about 22% higher root dry weight at 25 DAT, but 5-10% lower root dry weight at 50 and 75 DAT compared to BRRI dhan-31. The photosynthetic rate was higher (20 μ mol m-2/sec-1) in BRRI dhan-3l at 35 DAT (maximum tillering stage) but at 65 DAT, Sonarbangla-l had higher photosynthetic rate of 19.5 μ mol m-2 sec-1. BRRI dhan-3l had higher panicles/plant than Sonarbangla-1, but Sonarbangla-1 had higher number of grains/panicle, 1000-grain weight and grain yield than BRRI dhan-31. In 2002, BRRI dhan-31 had the highest plant height at 25 DAT, but at 75 DAT, BRRI hybrid dhan-l had the highest plant height. Sonarbangla-1 had the largest leaf area at 25 and 50 DAT followed by BRRI dhan-31, but at 75 DAT, BRRI dhan-31 had the largest leaf area. The highest shoot dry matter was observed in BRRI dhan-31 followed by Sonarbangla-1 at all DATs. Sonarbangla-1 had the highest rooting depth and root dry weight at all DATs. BRRI dhan-31 gave the highest number of panicles/plant followed by Sonarbangla-I, BRRI hybrid dhan-l had the highest grains/panicle followed by BRRI dhan-31 and Sonarbangla-I had the highest 1000-grain weight followed by BRRI dhan-31. The highest amount of grains/plant (34.6 g) was obtained from BRRI dhan-31. Key Words: Shoot dry matter; root dry weight; leaf area; photosynthesis; grain yield.

SUMMARYSix experiments were carried out over 2 years (1985 and 1986) in commercial spring barley crops on calcareous soils in Hampshire. Herbicides increased grain yield by 0·05–1·21 t/ha, and fungicides by 0·01–0·68 t/ha. Herbicide use affected each of the yield components ears/plant, grains/ear, 1000-grain weight and harvest index in one or more cases but the effects were not consistent between experiments or consistently related to yield increases. Fungicide use had little effect on yield components other than 1000-grain weight, which was significantly increased in all experiments. There were no significant herbicide × fungicide interactions. Large differences in yield were recorded between field edge (headland) and midfield plots, with headland plots outyielding the midfield in two of the three experiments where this effect was considered.The effects of fungicide use were accounted for by associated increases in the green lamina area of the flag leaf and second leaf at the late milk stage of grain development. This is consistent with previous work. Differences in yield response to herbicide between sites were linearly related both to weed numbers early in the season and to weed biomass at harvest. Weeds did not always directly replace crop biomass; in some experiments the combined dry matter production was greater when herbicide was not used. However, the results indicate that, where a diverse weed flora composed of species of moderate to low competitive ability is present, simple weed counts may provide a useful indication of potential yield loss.It is concluded that headland areas can often be as productive as the rest of the field, but a greater understanding of the factors involved is needed if this potential is to be realized.
