To investigate the effect of various transplanting dates on yield and yield attributing characteristics of Nerica rice mutants at drought prone areas, Ishurdi and Chapai Nawabgonj during aman season. Two advanced Nerica mutant lines (N4/350/P-4(5), N10/350/P-5-4) were evaluated compared with one check variety (Binadhan-17) with three dates of transplanting (D1=July 20, D2=July 30 and D3=August 10). The experiments were laid out on randomized complete block design (RCBD) with three replications. Twenty five days old seedlings were transplanted with optimum 20 x 20 cm row to row and plant to plant distance. The unit plot size was 3 m×4 m. The recommended doses of fertilizer were applied. The effect of dates of transplanting on grain yield of D3 was the highest (5.10 t ha-1) whereas D2 produced the lowest grain yield (4.24 t ha-1). Among the mutant lines/varieties, Binadhan-17 produced the highest grain yield (4.94 t ha-1) followed by N4/350/P-4(5) (4.57 t ha-1). The interaction effect of date and variety showed that Binadhan-17 produced the maximum yield (5.56 t ha-1) at D3 followed by N4/350/P-4(5) mutant (4.92 t ha-1). The interaction effect of date and location, D3 transplanting date produced the maximum yield (5.23 t ha-1) at Ishurdi which was followed by transplanting (4.96 t ha-1) at Chapai Nawabgonj. The interaction effect of variety and location Binadhan-17 produced maximum yield (5.06 t ha-1) in Ishurdi followed by Binadhan-17 in Chapai Nawabgonj (4.82 t ha-1). The interaction effect of date, variety and location transplanting date D3, Binadhan-17 produced maximum yield (5.70 t ha-1) in Ishurdi followed by transplanting date D3, Binadhan-17 in Chapai Nawabgonj (5.43 t ha-1). The data recorded on crop duration from transplanting to maturity revealed that the advanced mutant line N4/350/P-4(5) required the least average 108 days and the Binadhan-17 required maximum average 119 days. Therefore, 10th August was found to be the best date of transplanting and Binadhan 17 showed the best performance at Ishwardi in Bangladesh.

An experiment was carried out at Bangladesh Agricultural University, Mymensingh to evaluate the effect of urea super granule (USG) as a source of nitrogen on the yield and yield components of transplant Aman rice cv. BRRI dhan39, BRRI dhan46 and BINA dhan7. Five levels of N (viz., 0, 60, 120 kg ha-1 as prilled urea and 60 and 120 kg ha-1 as USG) were taken as experimental treatments. The experiment was laid out in a randomized complete block design with three replications. Plant height, effective tillers hill-1, grains panicle-1 and grain yield varied significantly due to different cultivars. All the yield and yield components except 1000-grain weight were influenced significantly by the levels of nitrogen fertilizer. The highest grain yield (4.82 t ha-1) was recorded in BINA dhan7 and the lowest one (4.30 t ha-1) was recorded in BRRI dhan39. Nitrogen @ 120 kg ha-1 as USG performed the best among the treatments in respect of yield and yield components of rice. The highest grain yield (5.46t ha-1) was obtained from BINA dhan7 with 120 kg N ha-1 as USG which was statistically identical with 60 kg N ha-1 as USG. A considerable amount (31.25%) of prilled urea (PU) nitrogen could be saved by using USG. It may be concluded that USG could be used as N management to achieve better nitrogen use efficiency in reducing N loss than the PU.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19095 Progress.

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh, during November 2008 to March 2009 to examine the effects of mimosa (Mimosa invisa) compost and phosphorus on the yield and yield components of lentil variety BARI Masur6. Two factors were: a) Mimosa invisa compost and b) phosphorus fertilizer. Mimosa invisa compost were used in four rates- 1 (M1), 5 (M2), 10 (M3) and 15 (M4) t ha-1. Five rates of phosphorus fertilizer were: ‘no’ phosphorus (P0), 25% RDP (P1), 50% RDP (P2), 75% RDP (P3) and 100% recommended dose phosphorus (TSP @ 85 kg ha-1) (P4). The experiment was laid out in a factorial randomized complete block design with three replications. Mimosa invisa compost had significant effect on the crop characters except number of branches plant-1. The highest seed yield (1435.33 kg ha-1) was observed in M2 treatment (5 t ha-1) and the lowest seed yield (1220 kg ha-1) was observed in M4 treatment (15 t ha-1). Phosphorus had a significant effect on all the plant characters. The highest seed yield (1464.17 kg ha-1) was observed in P4 treatment (100% RDP) and the lowest was observed in P0 treatment. The interaction effect of Mimosa invisa compost and phosphorus on the yield of lentil was significant. The highest seed yield was observed (1630 kg ha-1) in M2×P4 treatment and the lowest was in M3×P0 treatment (1000 kg ha-1).

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from June to December 2012 with a view to finding out the effect of seedling age and method of transplanting on the yield of Aman rice. Four seedling ages (10, 20, 30 and 40 days) and two transplanting methods (line and haphazard) were used as experimental treatments with four replications in a randomized complete block design. Seedling age, transplanting method and their interaction significantly influenced most of the yield components and yield of transplant Aman rice cv. BRRI dhan41. The highest total tillers, effective tillers hill-1, grains panicle-1, grain yield, straw yield and harvest index were obtained from 30-day-old seedlings. Line transplanting method produced the highest total tillers, effective tillers hill-1, grain yield and harvest index. The highest total tillers, effective tillers hill-1, grain yield and harvest index were obtained from 30-day-old seedlings with line transplanting method. Results revealed that 30-day-old seedlings under line transplanting method could be used to obtain maximum yield of transplant Aman rice cv.

Effect On Yield

An experiment was conducted to evaluate effect of urea fertilizer on yield and yield components of Zea mays L. Using Randomized Complete Block Design (RCBD) split plots in three replications in agricultural research farm of Balkh University by 2019. Doses of urea used in this experiment were 0, 80, 160 and 240 kg ha-1 , respectively. It has been found that amount of nitrogen fertilizer (urea) had significant effect on yield of maize at p<0.05. The higher level of nitrogen caused the higher grain yield, number of kernels per ear, the number of grains per ear row, ear diameter, cob length, grain per plant and plant height. As a result 7.76 ton ha-1 was recorded as high yield while 240 kg ha-1 urea was used, and 5.12 ton ha-1 was recorded as low yield in treatment one with 0 kg ha-1 of nitrogen fertilizer. Finally, as a result using 240 kg ha-1 nitrogen fertilizer is recommended.

Hybrid rice technology is one of the promising, sustainable, and proven technologies for increasing rice production and productivity with a yield advantage of 15–30% over modern inbred varieties. The potential of hybrid rice has so far not been exploited in Ghana. This study was undertaken to evaluate the yield potential, reaction to diseases, and physical grain attributes of some introduced hybrids. The trials were laid out in a randomized complete block design (RCBD) with three replicates across three locations. Data were taken on grain yield, yield components, reaction to diseases, and grain physical characteristics. Four promising hybrids (SWARNA 2, ARGH 1501, ARGH 1502, and ARGH 1503) with a mean yield advantage of 15–20.8% over the best inbred check “AgraRice” were identified. With few exceptions, the hybrids were broadly adapted and had adequate resistance to blast and bacterial leaf blight. Most of the test hybrids had long slender grains which make them acceptable to the Ghanaian market but lacked aroma.

Segregation pattern of the Soybean Stunt Virus resistant character and genetic diversity of F2:3 families derived from crosses between Orba and B3570.  Soybean stunt disease caused by SSV (Soybean Stunt Virus) is the most destructive soybean disease in Indonesia. This research was conducted from October 2005 to June 2006 at experiment station of Lampung University.  The aims of this research were to evaluate the segregation of resistant characters and total genetic diversity of eight populations of F2:3  families. Experiment was arranged in a randomized complete block design with three replications. The resistance was evaluated based on the score of disease severity.  The results showed that the resistant characters segregate 1:2:1 to susceptible, moderately resistant, and resistant, respectively based on  the segregation pattern. The resistant character was controlled by single gene and the action of the gene is noncompletely dominant gene.  Eight populations of F2:3 families have high diversities on the yield and yield components.

A field experiment was conducted to assess the influence of N fertilizer rates on growth, grain yield and yield components of Tef [Eragrostis tef (Zucc.) Trotter], in 2017 main cropping season. Three tef varieties (Kora, Boset and Asgori) and five Nitrogen rates (0, 30, 60, 90 and 120kg N ha-1) were used in Randomize Completed Block Design with three replications with the same dose of Triple Super Phosphate. The total and productive tiller number were highly (P<0.01) significantly affected by varieties. The control plot had maximum days to heading and this may be due to nitrogen fixation may exist and its availability may be deficient in the soil. The less response to the N rate may be due to variability of fertility or soil N content, and genetically difference between varieties. From means of varieties, the early flowerings of Boset and Asgori varieties were 101.4 and 103.79 days to maturity, respectively, but Kora (108.9 days) was late matured. Kora had maximum plant height (135.9cm) and panicle length (56.07cm) followed by Boset (115.1cm) and (42.49cm) respectively. The lodging index was affected by N rates and Kernel weight was highly significantly (P<0.01) affected only by varieties. The highest mean of thousand kernel weight (0.3387) was noted from Asgori variety. The grain yield was decreased with N rates and a better grain yield was obtained at 60-90kg N ha-1. Overall N rates indicated that, both Kora (1800) and Boset (1883) had a better grain yield in kg ha-1, but Asgori had lowest grain yield (1560kg ha-1). Based on the economic point of view, it would be more profitable to use 60kg N ha-1 N rates.

Abstract The aim of this study was to examine the genotype by environment interaction for grain yield and to identify high-yielding and stable mutant lines of 6-rowed winter barley under different growing seasons. The study was carried out during 7 growing seasons from 2010 – 2011 to 2016 – 2017 in the experimental field of the Institute of Agriculture – Karnobat, Southeastern Bulgaria. Fourteen advanced mutant lines and the check variety Vesletc were studied using a complete block design with 4 replications. The AMMI analysis of variance indicated that 20.54% of the variation for grain yield was explained by the effect of genotype and 37.34% and 42.12% were attributable to the environmental effects and genotype by environment interaction. The magnitude of the genotype by environment interaction was two times larger than that of genotypes, indicating that there was a substantial difference in genotype response across environments. The AMMI and GGE biplot analyses identified G9 as the highest yielding and stable genotype. This mutant line can be recommended for further evaluation for variety release. The mutant lines G6, G13 and G15 were suggested for inclusion in the breeding program of winter barley due to its high grain yield and intermediate stability.
