A field experiment on foxtail millet was laid out under irrigated and rainfed condition to screen semi drought tolerant lines. Parameters studied, like plant height, total dry matter accumulation and yield decrease under rainfed condition as compared to that under irrigated conditioned. It is observed that out of 19 lines, considering plant height stress index, seventeen lines showed tolerance above the test crop (Titas). The lines HYM 11/BSi 427, HYM 12/BSi 467, EM 15/BSi 467 and BSi I showed better tolerance than the test crop when dry matter stress index was considered. Nine lines out of 19 showed better yield stability ratio as compared to test crop (Titas). It is observed that greater the tolerance index, larger is the yield gap between normal and stress condition. Considering all the parameters like PHSI, DMSI , TOL, YS ratio, drought susceptibility index and also the visual observation, the lines BSi-1, EM 15/ BSi 467 and EM 8 /BSi 467 showed better performance than the test crop.

A field experiment was carried out at Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar, India to evaluate the performance of pearl millet genotypes (HHB 67 ‘Improved’, HHB 197, HHB 223 and HHB 234) under different environment (rainfed and irrigated). Results showed that irrigated condition recorded significantly (p < 0.05) higher plant height, dry matter accumulation, root dry weight, ear head girth, test weight and yield of pearl millet than rainfed condition. Root length was significantly (p < 0.05) higher under rainfedthan irrigated condition. Genotypes were found significant (p < 0.05) with respect to plant height at harvest and HHB 234 recorded higher plant height. Genotype HHB 223 recorded higher earhead girth (2.6 cm) and test weight (11.16 g) compared to other genotypes. Interaction effect was also found significant (p < 0.05) with respect to plant height, dry matter accumulation, root length and weight and yield. These were higher in genotype HHB 223 and HHB 234 under irrigated and rainfed condition respectively but at 20 days after sowing, longest root was observed in genotype HHB 67 ‘Improved’ under rainfed condition and genotype HHB 197 under irrigated condition. To examine the performance of pearl millet genotypes in terms of survivality and yield potential, evaluation trials are necessary under different environment. Therefore, release of those varieties under different situations are essential for the sustainability of the fragile arid and semi arid regions of country.

Intraspecific variations in wheat growth responses to elevated CO2 was evaluated using 20 Iranian bread wheat (Triticum aestivum L.) cultivars. The plants were grown in the modified Hoagland nutrient solution at a greenhouse until 35 days of age using two levels of CO2 (~380 and 700 µmol mol–1). The shoot and root dry weights of the wheat cultivars exhibited average enhancements of 17% and 36%, respectively, under elevated CO2. This increase was associated with higher levels of chlorophyll a (25%), chlorophyll b (21%), carotenoid (30%), leaf area (54%) and plant height (49.9%). The leaf area (r = 0.69**), shoot N content (r = 0.62**), plant height (r = 0.60**) and root volume (r = 0.53*) were found to have important roles in dry matter accumulation of tested wheat cultivars under elevated CO2 concentration. However, responses to elevated CO2 were considerably cultivar-dependent. Based on the stress susceptibility index (SSI) and stress tolerance index (STI), the wheat cultivars exhibiting the best response to elevated CO2 content were ‘Sistan’, ‘Navid’, ‘Shiraz’, ‘Sepahan’ and ‘Bahar’, while the ones with poor responses were ‘Omid’, ‘Marun’, ‘Sorkhtokhm’ and ‘Tajan’. The findings from the present experiment showed significant variation among the Iranian wheat cultivars in terms of their responses to elevated air CO2, providing the opportunity to select the most efficient ones for breeding purposes.

To investigate the effects of trifluralin, chlorimuron and clomazone on morphology and assimilate partitioning during soybean development, plants were grown in a greenhouse and sampled at 14-day intervals. Clomazone reduced stem and leaf dry matter accumulation at 14 days after emergence (DAE), while trifluralin and chlorimuron reduced plant part dry matter accumulation up to 28 DAE. The number of leaves, plant height, mass and number of pods and seeds, and the shoot/root ratio were not influenced by the herbicides. Roots, stems and leaves were the preferred sinks up to the R2 growth stage, while pods and developing seeds became the preferred sinks later. This order was not altered by the herbicides.

This study aimed to evaluate different substrates to produce yellow passion fruit seedlings. For this purpose, an experiment was carried out in a greenhouse, from April to June 2016. A completely randomized design with five replications, in a 6 x 5 factorial scheme was used. The first factor was the alternative substrates (poultry, cattle and equine manure, sugarcane and coconut bagasse, and Organomais compost). The second factor was the replacement levels to the commercial substrate of Plantmax® (100:0, 75:25, 50:50, 25:75, 0:100). The seedling evaluation was carried out 42 days after sowing. The following variables were analyzed: length, width, and the number of leaves; plant height and shoot dry matter. A significant effect (P0.05) for the interaction between the factors was verified. The addition of 60% cattle manure and Organomais to the commercial substrate Plantmax® promoted greater length, width, and the number of leaves, plant height, and shoot dry matter accumulation in the yellow passion fruit seedlings.

A field experiment was conducted under humid subtropical agro-climatic condition of Nepal during rainy season of 2014. The experiment was laid out in to two factor Randomized Complete Block Design with  three replications consisting three drought tolerant rice varieties (Sukhadhan-4, Sukhadhan-5 and Radha-4) and four planting geometry (15 cm × 10 cm, 15 cm × 15 cm, 20 cm × 15 cm and 20 cm × 20 cm). The results revealed that the highest plant height and maximum leaf area index was recorded in planting geometry 15 cm × 10 cm in all growth stages. Whereas, planting geometry 20 cm × 15 cm produced the maximum number of tiller m-2 in all growth stage.  While planting geometry 20 cm × 15 cm and 20 cm × 20 cm produced statistically similar crop growth rate and dry matter accumulation in all stage of growth. Regarding the varieties, Sukhadhan- 4 showed highest plant height up to 75 DAT and plant height was statistically similar to Radha - 4 in 60 and 75 DAT. But maximum number of tiller m-2, leaf area index, crop growth rate and dry matter accumulation were recorded in Sukhadhan – 5 varieties. Int. J. Appl. Sci. Biotechnol. Vol 5(4): 423-429

An experiment was conducted at Punjab Agricultural University, Ludhiana during 2015 and 2016 to study the effect of priming, different seed rate on growth and seed yield of soybean planted under bed and flat method. The study was planned in factorial split plot design, keeping two planting techniques (flat sowing and bed sowing) and two seed priming treatments ( non primed seeds and 100 ppm GA3 primed seeds) in main plot and three seed levels ( 50, 62.5 and 75 kg ha-1) in sub plot. The objective of the study was to evaluate the effect of seed priming on growth and productivity under different planting techniques with the use of varying seed rates. The results revealed that growth attributes viz. emergence count, plant height, dry matter accumulation, leaf area index and photosynthetic active radiation interception (%) was significantly higher under bed planting technique as compared to flat sowing method. The pooled seed yield was increased by 15.6 % in bed planted soybean crop as compared to flat planted crop. Soybean seeds primed with 100 ppm GA3 recorded significant results in all the growth parameters. Primed seed recorded increase in yield 15.3 % than non primed seeds. Seed rate of 62.5 kg ha-1 recorded significantly higher emergence count, plant height, dry matter accumulation, leaf area index and photosynthetic active radiation interception (%) which was statistically similar in results with 75 kg ha-1 seed rate in both the two years. Pooled seed yield of 62.5 kg ha-1seed rate was 4.61 % higher than 75 kg ha-1 and 12.6 % than 50 kg ha-1 seed rate.

Field trials were conducted during the rainy season of 2017 at Teaching and Research Farm of Bayero University and Kano State Livestock development Centre Dangora. To determine the magnitude and nature of the association between growth characters and grain yield of maize, as well as the percentage contribution of each of this independent variable on the dependant variable (yield).The trails consist of six weed control methods, three levels of poultry manure and three varieties of maize. The experiment was laid out in a split-split plot design with variety allocated to the main plot, poultry manure to the sub-plot while weed control method to the sub-sub plot, and was replicated three times.  Grain yield correlated positively and significantly with growth and yield characters evaluated while weed dry weight and weed index were highly negatively correlated. The direct and indirect contributions results indicate that plant height had the highest direct contribution at BUK and Dangora in 2016 and Doka 2017 while plant dry matter accumulation had the highest direct contribution at Dangora in 2017. Cob diameter had the least direct effect in the study; the highest indirect effect was from cob diameter through plant height. The percentage individual contribution to grain yield showed that plant height made the highest contribution at BUK and Dangora in 2016, while cob diameter at both locations and plant dry matter at Dangora resulted in the least contribution. The combined contribution of dry matter and 100-seed weight was the highest positive contribution at BUK and that of plant height via 100-seed weight all in 2016 while cob length via 100-seed weight made the least negative contribution at BUK.

Background: Groundnut as a sole crop is affected by adverse weather conditions coupled with damage by insect, pest and disease, results in economic losses and in extreme cases complete failure of the crop. Intercropping is one of the important cropping systems recommended to mitigate the aberrant climatic conditions with an aim to increase total productivity per unit area. The present study was done to assess the effect of different millet based intercropping system on growth and yield of groundnut under rainfed condition. Methods: A field experiment was conducted during kharif 2018 and 2019 at Agricultural Research Farm of All India Coordinated Research Project on Groundnut, OUAT, Bhubaneswar on mixed red and black medium soil. The experiment was laid out in randomized complete block design and replicated thrice. It consisted of ten treatments comprising of groundnut with three millets viz., finger millet, little millet and foxtail millet. Millets were intercropped with groundnut in the replacement series of 4:2 and 2:1 row proportion along with mono-cropped millets and groundnut. Result: Significantly higher no. branches/plant (5.2), leaflet/no. plant (79.33) and dry matter accumulation (25.77g/plant) was recorded in groundnut + finger millet (2:1) whereas, sole groundnut incurred significantly higher pod no/plant (16.5), 100 kernel weight (37.2g), shelling% (77.8), pod yield (1736 kg/ha) and haulm yield (3613 kg/ha) over all other intercropping systems. Further, groundnut pod equivalent yield (GPEY), land equivalent ratio (LER), area time equivalent ratio (ATER) and economics were higher in 2:1 row ratio of groundnut + finger millet compared to any of the sole and intercropping systems. The competition ratio and aggressivity of little millet was greater than that of other millets. So, it was most dominant crop over groundnut compared to other millets in the intercropping systems.

Background and Objective: Sulphur and boron are found as most critical nutrient elements for the better growth and yield of mustard crop however no such concrete information for their uses in field production of this crop is yet to be reported. Therefore, an experiment was conducted to investigate the effect of agronomic biofortification of sulphur and boron nutrients on the growth and yield of mustard crop. Study Design: The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replicates. Place of Study: The experiment was carried out in the Crop Botany Field Laboratory, Bangladesh Agricultural University, Mymensingh. Methodology: Three doses of sulphur (S) viz. 0, 20 and 40 kg ha-1 and three doses of boron (B) viz. 0, 0.5 and 1.0 kg ha-1 and their possible combinations were used as basal doses. Field data were collected from periodic destructive samplings on the plant height, number of leaves and branches per plant, total dry matter accumulation and finally yield components and yield. Results: Sulphur and boron fertilizations significantly influence the plant height, production of branches and leaves per plant, dry matter accumulation and yield attributes and yield of mustard crop. The mustard crop fertilized with 40 kg S ha-1 in combination with 1 B kg ha-1 produced taller plant, higher number of branches and leaves in each plant and higher amount of dry matter per plant while these plant traits were found as minimum when the growing the mustard crops in control plots i.e. the plants received neither sulphur nor boron. Application of sulphur @ 40 kg ha-1 along with boron @ 1 kg ha-1 produced the highest seed yield (2.73 t ha-1) whereas the lowest seed yield (1.08 t ha-1) was found where no sulphur and boron were applied. Conclusion: The result conclude that combine application of sulphur and boron @ 40 and 1 kg per hectare, respectively was found to be most effective dose in enhancing growth and yield of mustard crop.

A study was carried out in the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Old Brahmaputra Flood Plains Soil (AEZ-9) during December 2001 to April 2002 to find out the effect of seed rates and NPK levels on dry matter accumulation and grain yield of foxtail millet (Setaria italica L. Beauv.). Four seed rates viz., 8,10,12, and 14 kg/ha and five levels of NPK fertilizers viz., N0P0K0, N10P8K5, N20P16K10, N30P24K15, and N40P32K20 were included in a split plot design with three replications. Dry matter accumulation pattern was determined by harvesting 10 plants randomly at 30, 60, 80, and 102 DAS (days after swing). The yield and yield contributing characters of foxtail millet were influenced by seed rates and NPK levels except tillers per plant and 1000-grain weight significantly. Generally its production rate was 0.86 t/ha when it was grown in char lands in sandy loam soils, the highest grain yield (1.62 t/ha) was produced by 10 kg seeds/ha, which was identical with 12 kg seeds/ha. In case of NPK levels, the treatment was N30P24K10. In case of interaction, the treatment combination 12 kg seeds/ha and N30P24K15 produced the highest grain yield (1.77 t/ha. In case of interaction, the treatment combination 12 kg seeds/ha and N,sub>30P24K15/ha gave the highest grain yield. DOI: http://dx.doi.org/10.3329/bjar.v38i4.19661 Bangladesh J. Agril.
