Abstract In a two year experiment carried out on the organic research plots of the Institute of Food Security, Environmental Resources and Agricultural Research, Nigeria. Two liquid organic fertilizers (ARATI NAWOZ {2.01% N} and ARATI BAJA {1.01% N}) and control were applied to four sunflower varieties (SAMSUN 1, SAMSUN 2, SAMSUN 3 and SAMSUN 4) during the late cropping season (July – Nov.) of 2016 and 2017 to evaluate their agronomic response. The experiment was laid out in a randomized complete block design using a 4 × 3 factorial arrangement in three replicates. Data were collected on plant height at maturity, head diameter and weight, weight and number of seeds per head, 100 seed weight and seed yield. The varietal effect was significant (P < 0.05) on head diameter and weight, and number and weight of seeds per head, and seed yield in 2016. However, during the markedly dry 2017, the varietal effect was not significant for any trait measured. Foliar application of ARATI NAWOZ significantly (P < 0.05) increased height at maturity, the weight of seeds and head per plant and seed yield relative to the control in both years. Significant Variety × Fertilizer interaction effect was also recorded on the height at maturity, head diameter and weight, and seed yield in 2016. SAMSUN 4 (975.6 kg/ha) produced significantly (P < 0.05) higher seed yield than SAMSUN 1 (789.82 kg/ha) and SAMSUN 2 (778.54 kg/ha) in 2016. The efficacy of the application of both fertilizers was on par for most traits in both years. On average, the application of organic fertilizers resulted in a 15.76 and 69.02% increase in seed yield relative to the control in 2016 and 2017, respectively. ARATI NAWOZ and ARATI BAJA appeared promising for sunflower production in the humid tropics.

Abstract A field experiment was carried out using four inbred lines of maize BK112, Inb17, ZP607 and Zm6, as they were entered into half-diallel cross-breeding program in the fall season 2019, and 10 genotypes (6 crosses + 4 parents) were obtained according to the second Griffing method, the first model, in the spring season of 2020, the behavior of these inbreds and their hybrids were evaluated with three irrigation intervals with the aim of obtaining one or more distinct hybrids of pure strains derived from maize Zea mays L. under the irrigation interval and the study of hybrid vigor. The experiment was carried out in the fields of a farmer in Anbar Governorate, using the RCBD randomized complete block design (split – plot) with three replications. The irrigation interval (4, 8 and 12) days occupied the main plots, while the inbred and hybrids occupied the sub-plots. The results of the statistical analysis showed a significant effect of genotypes on the studied traits. The studied hybrids Zm6 × ZP607 were distinguished by their weight of 300 grains and the grain yield (85.83 g and 186.70 g) respectively. The plants grown under the irrigation interval 4 days outperformed the grain yield of the plant by giving it the highest yield of 156.03 g. It did not differ significantly with the 8-day irrigation interval, while the yield decreased significantly at the 12-day irrigation interval with a decrease of 120.8% and 120.5% than the 4 and 8 irrigation treatments, respectively. It was also found that the interaction was significant and reached the highest grain yield with an irrigation interval of 8 days, 224.0 g. The hybrid Zm6 × ZP607 gave the highest positive hybrid vigor for individual plant yield, which was 119.24%, 126.72% and 166.05% for the irrigation interval of 4, 8 and 12 days, respectively. Therefore, the plant breeder can use the characteristics of the yield components as selection guides with the superior hybrids in yield and the strength of the hybrid.

Head size contributes substantially to seed yield of sunflower because it influences both number of seeds per head, and seed size. The aim of this field study was to determine the variability of head diameter in sunflower hybrids depending on planting date across three cropping seasons. Three hybrids (Miro, Rimi, Pobednik) were sown at four planting dates (PD1 - 20th of March, PD2 - 10th of April, PD3 - 30th of April, PD4 - 20th of May). Head diameter was analysed in the stage of flowering and physiological maturity. The trial was arranged as Randomized Complete Block Design (RCBD) with four replications. Analysis of variance (ANOVA) showed that the effect of year, hybrid, planting date and most interactions were highly significant for head diameter in the flowering stage. In the stage of physiological maturity head diameter varied significantly depending only on the planting date. Also, all interactions, except year ? hybrid (Y ? H), were highly significant. Planting date had significant influence on head diameter in the stage of flowering and physiological maturity in sunflower. With later sowing head diameter increased, so that significantly highest head diameter across planting dates was found in PD4 (11.8 cm in flowering stage, and 22.6 cm at the stage of physiological maturity). Study results may be helpful in the recommendation for optimal planting date in sunflower.

A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur for 2 consecutive years during 2006-07 and 2007-08. The objectives were to find out the optimum nutrient management practice on tuber yield, nutrient balance and economics of potato cultivation. Twelve nutrient management treatments were tested in a randomized complete block design with 3 replications. Treatments were T1=HYG (0-198-44-194-24-6-1.2), T2=MYG (0-140-34-138-18-4.5-0.9), T3=IPNS (10000-168-38-170-18-6-1.2), T4=STB (0-171-40-164-22-5-1), T5=FP (0-97-16-91-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg ha-1 CDNPKSZnB for potato. The highest tuber yield of potato was obtained from STB+CRI (27.64 t ha-1) followed by IPNS+CRI (27.35 t ha-1), STB (27.10 t ha-1), IPNS (26.83 t ha-1), HYG+CRI (26.52 t ha-1) and HYG (26.10 t ha-1) in 2006- 07. Similar trend was found in 2007-08. The highest tuber yield and yield contributing parameters were noticed in CRI plots than without CRI. Except N, remaining nutrient balance like P K S Zn and B were found positive in case of HYG, MYG, IPNS and STB along with or without CRI nutrient managements. The balance was found almost negative in case of FP and CON. The highest BCR was observed in STB+CRI (3.96) followed by STB (3.93), IPNS+CRI (3.76), and IPNS (3.74). The higher gross return (Tk. 283331 ha-1) and also gross margin (Tk. 211761 ha-1) was observed from the same treatment. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22544 Bangladesh J. Agril.

Abstract Development of maize hybrid for tidal swampland was initiated by selecting and combinate some superior line genotypes that tolerate to the restrictions in target environment. This study aimed was to evaluate the capability of ten maize lines result of selection on tidal swamp acid sulphate soils to obtain GCU, GCA, and heterosis values based on parental yield averages. The experiment has consisted of ten fine line genotypes which have selected in 2019 at the tidal swamp. Each parent was crossed in half-diallel combination, resulting in 46 entries, including the inbred parents. The entries were planted in a randomized complete block design with three replications. The research was conducted on Bajeng Research Station Experiment 5°18’S and 119°30’E from September 2020 to January 2021. The result shows that GCA ability and SCA ability was significant to yield in the form of grain (15% moisture content), the number of ear per plot, ten ear weight, ten corncob weight, ear harvested weight, 1000 seeds weight, plant height, ear length and the number of seed per ear. Grain yield of W6xW9 crosses obtains the highest value of 9.36 tha−1, non-significantly different to hybrid check P35 (9.35 tha-1). The highest GCA value in the grain yield character was obtained on W9 parental line (0.64**). The highest SCA was obtained on the crossing of W7 x W8 (2.61). The highest heterosis value was revealed in W5 x W10 hybrid (4.80). However, W7 x W8 crossing heterosis value was 2.34, indicate that a high SCA effect did not usually generate high heterosis. To perform high heterosis value, W10 was good as female parental.

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.

An experiment was carried out at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna during 2013-15, with eleven genotypes of plantain to evaluate their performances for yield attributes, yield and quality characters. The genotypes included in this investigation were MP001, MP002, MP003, MP006, MP007, MP015, MP018, MP024, MP025, ISD002 and BARI Kola-2 as check. The experiment was laid out in randomized complete block design with three replications. The genotype MP002 produced the maximum number of fingers/bunch (105.67) closely followed by BARI Kola-2 (103.00) and MP015 (101.00). Both the genotypes MP024 and MP025 showed the highest fruit length (21.70 cm), but ISD002 gave the maximum fruit girth (16.78 cm), which was statistically similar with that of MP003 (16.30 cm) and MP024 (16.33 cm). The highest yield and the maximum number of hands were produced by the genotype MP024 (47.81 t/ha and (8.33/bunch) followed by MP015 (36.70 t/ha and 6.33/bunch). Fingers of the genotypes required boiling time in the range of 20.00 min (MP001) to 15.00 min (BARI Kola-2). Flesh of all genotypes possesses pleasant aroma except MP002, MP003 and ISD002. Among the eleven genotypes MP001, MP006, MP007, MP008, MP015 and MP024 were found better when cooked as smashed. The genotype ISD002 took the maximum time (467.33 days) to reach the edible maturity stage of fruits whereas MP024 required the minimum (339.00 days). The genotypes MP015 and MP024 performed better than BARI Kola-2 in respect of bunch weight, fruit size, productivity index, yield, sucker production and qualitative characters.Bangladesh J. Agril.

A field experiment was conducted at Agricultural Research Station, Baljigapade, Chikkaballapur taluk and district, which comes under the Eastern Dry Zone of Karnataka during Kharif season 2018. The experimental plot in the field was laid out following a randomized complete block design (RCBD) with fourteen treatments and three replications. The treatments included two levels of N and P2O5 (20 and 30 kg ha-1) and three levels of K2O (10,20 and 30 kg ha-1). Farmyard manure was applied at the rate of 6.25 t ha-1 to all the treatments except absolute control. Results indicated that application of 30 kg N+30 kg P2O5+30 kg K2O ha-1 with Farm Yard Manure (FYM) increased the micronutrient availability in soil N (150.29 kg ha-1), P2O5 (17.60 kg ha-1), K2O (160.84 kg ha-1). Application of FYM @ 6.25 t ha-1+30 kg N+20 kg P2O5 +20 kg K2O ha-1 significantly increased growth, yield, macronutrient content and uptake by brown top millet grain and straw against absolute control. The grain yield of browntop millet was increased by 61.46 percent in T10 and 59.07 percent in T9 as compared to the absolute control.

The field experiment was conducted in the season of 2017-2018 at the Agricultural Research Department-AL-Azafrinih/Baghdad-Iraq. This study aimed to determine the effect of adding the Foliar Fe fertilization (Nano-Fe) and ground fertilization of (N, P) in the growth and production yield of rapes (Brassica napus L.). The experiment included three levels of foliar fertilization (Nano-Fe) that is (0, 5, 10 Kg. ha-1) and one level of ground fertilization (N 100 Kg. ha-1, P 250 Kg. ha-1). The experiment designed according to Randomized Complete Block Design (R.C.B.D) with three replications each parameter. The studied traits were nutrients content (macro-micro) in seeds and soil, the percentage of protein, oil, and carbohydrate. All data were analyzed and used statistically. Results showed a significant difference between Nano-Fe fertilization and nutrient content (N, Mn, K, Ca, Mg, S, and Cu), pH in soil at the level of 10 kg. ha-1, compared to no-fertilization. Moreover, the significant difference between Nano-Fe fertilization, yield (1425.6 kg. ha-1), the percentage of oil (52.16%), protein content in seeds (46.5%), carbohydrate (26.8%), Nutrient content N and P in seeds at the level of 10 kg. ha-1, compared to no-fertilization and the nutrient content (Ca, Mg, Fe) in seeds at levelof5 kg. ha-1, compared to no-fertilization. Current results suggested that Nano-Fe fertilization at the level of 10 kg. ha-1 can be adopted as the best level for rapes (Brassica napus L.) cultivation under semi-arid conditions.
