The Impact

Due to its valuable properties, Saffron is considered one of the most expensive spices. Saffron was introduced to Lebanon in 2000 and promoted as alternative crop to Canabis Sativa. There has been little research for saffron on a variety of subjects, in particular on cultural practices. The aim of this study is to investigate the impact of corm density on Saffron yield attributes. The study included three corm densities that were organized in randomized complete block design with three replicates; Low(LD)-25 corms m-2, 20 × 20 cm spacing; Moderate (MD)-44 corms m-2, 15 × 15 cm spacing; High (HD)-100 corms m-2, 10 × 10 cm spacing. The study was conducted at the Lebanese agricultural research institute (LARI) in Lebaa station for four consecutive years. Results showed a steadily significant high yield of flowers m-2 at high density compared to low density for four years .In contrast, the number of flowers (NF)/100 corm clusters (CC) was significantly increased at low density in last two years compared to high density. Treatments showed no significant effect of the main compounds of air-dried stigmas (Crocin, Picrocrocin and Safranal). Fresh (FWSS) and dry (DWSS) weight of single stigma was affected by year showing a significant change from year to year. These results revealed that success of long-term cultivation can be achieved by planting saffron corm at moderate and low densities.

An experiment was conducted in order to identify the productive genotype of turmeric for the plains of Nepal. In 2017 and 2018, seven promising turmeric genotypes (CI 0207, CI 0205, CI 9102, CI 1312, CI 0503, CI 0507, and CI 0201) were compared with KKH-1 in a Randomized Complete Block Design with four replications at the Directorate of Agricultural Research, Tarahara, Nepal. The plants were 30 cm x 30 cm apart, with 40 plants per 3.6 m2 plot area. Cultural practices were followed in accordance with the recommendations. Analysis of variance, correlation, cluster, and GGEbiplot analysis were performed on the observed data. From the pooled analysis of two years of data, the results showed significant differences in plant height and fresh rhizome yield among genotypes. The rhizome yield of KKH-1 was found significantly higher (19.36 t ha-1) than CI 0205 and CI 9102 and at par with other genotypes. Weight of mother rhizome had significant positive correlation (r = 0.602**) with yield of fresh rhizome. Though KKH-1 yielded the highest fresh rhizome, the cluster and GGEbiplot analysis identified CI0207 as one of the potential turmeric clones next to KKH-1.

The success of Sorghum varieties introduced to a location is tightly linked to the uses, environmental condition and farmers’ preferences. Also, grain and stover quality needs special attention to enhance the market value. The farmers in Turare village are predominantly sorghum and millet farmers. They cultivate the same varieties of sorghum which are low yielding land races. Experiments were conducted in 2017 and 2018, nine varieties of sorghum were planted in the Agroforestry farm layout of Federal University Dutsin-Ma with the aim of determining the varieties that are high yielding, early and farmers’ preference varieties so that the varieties that are high yielding and preferred by farmers can be multiplied and distributed to the farmers. Four landraces from the local community and five hybrids from Institute for Agricultural Research, Ahmadu Bello University Zaria were used for the study. Complete Randomized Block Design was used for experimental design and the Sorghum varieties were allocated to plots using Random Table Number. In both years, the farmers (male and female) preferred Samsurg 45 and 46 because of their earliness and high yield. Also, the local varieties, Maibakincona and Yargidanwudu have high performance in both years. CSR01 and CSR02, Zago and Jandawa performed poorly in yield and are late varieties. Though Samsorg 40 had high yield but not as high as Samsorg 45, 46, Maibakincona and Yargidanwudu. The study concludes that Samsorg 45 and 46 have a better attribute of early maturity and yield. Also, the local varieties, Maibakincona and Yargidanwudu have high performance in both years and can be improved upon in terms of yield and earliness. This research was conducted in order to compare the performance of the hybrids varieties with the local varieties that the farmers are used to in the area so as to advise the local farmers to use the varieties with the highest performance. This will relatively translate to higher income for the farmers.

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.

A pot experiment was carried out in the nethouse of Soil Science Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during 2014-2015 through 2015-2016. The design of the experiment was factorial randomized completely block design with 4 replications. The objectives of the study were to evaluate the potential of Arbuscular mycorrhization (AM) on the germination, yield and yield attributes of lentil treated with different concentration of sodium chloride (NaCl). Five NaCl treatments (0, 1, 2, 3 and 4%) possessed NaCl level as the first factor that were treated with soils before sowing of lentil seeds overriding or pivotal pulse crop in Bangladesh. The second factor consists of mycorrhizal and non-mycorrhizal treatments. Mycorrhizal plants showed better performance in terms of germination %, yield and yield contributing characters than non-mycorrhizal plants. With increasing NaCl concentration germination %, yield and yield contributing characters in the rhizosphere soil, decreased significantly (p<0.01). Interaction effects of mycorrhizal inoculation and NaCl on germination %, growth and yield of lentil were appeared to be statistically non-significant. The highest germination (96.25% in 2014-2015 and 92.50% in 2015-2016), seed yield (6.45 g pot-1 in 2014-2015 and 5.89 g pot-1 in 2015-2016), and stover yield (9.55 g pot-1 in 2014-2015 and 8.58 g pot-1 in 2015-2016) was found in NaCl 0% + AM treatment. The lowest germination %, seed yield and stover yield was found in NaCl 4% treatment. Mycorrhizal inoculation increased seed yield on an average by 31.85% during 2014-2015 and 63.71% during 2015-2016, and increased stover yield on an average by 48.56% during 2014-2015 and 63.55% during 2015-2016 over non-mycorrhizal inoculation. Therefore, it can be concluded that mycorrhizal inoculation increases germination %, growth and yield of lentil over non-mycorrhizal inoculation. The Agriculturists 2017; 15(1) 156-169

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.

Abstract This experiment was conducted to evaluate various systemic insecticides applied as soil or transplant water treatments followed by foliar applications of Orthene for TA and TFB control on fluecured tobacco and to determine the impact of treatment on tobacco yield and price. The experiment was conducted at the VPI & SU Southern Piedmont Agricultural Research and Extension Center, Blackstone, VA. Eleven treatments and an untreated control were established in a randomized complete block design with 4 replications. Plots, 4 × 40 ft (1 row × 24 plants), were separated by single guard rows. Pretransplant soil treatments of most liquid formulations were applied broadcast with a CO2-pressurized tractor sprayer that delivered 30.4 gal/acre at 40 psi through 8003LP tips on 29 Apr (Ambient temperature, 85-89°F, soil temperature, 75°F; soil pH, 5.8; OM, 2%). Treatments were immediately incorporated by double disking. The Furadan and Temik treatments were applied during bed formation and immediately covered with 6 to 8 inches of soil on 17 May. Furadan 4F was diluted 50:50 in water and applied in a narrow stream (&lt; 1-inch wide) in the row using a peristaltic pump. Temik was applied in a 14 inch band using a tractor mounted- Gandy granular applicator. The soil moisture was good for both the pretransplant soil and bedding treatments. ‘K-326’ flue-cured tobacco was transplanted into experimental plots in a Chesterfield-Mayodan-Bourne sandy loam soil on 18 May. A measuring cup was used to apply transplant water (TPW) treatments of Orthene and Admire in 4 fl oz/plant (204 gal/acre) at the base of each plant in the treatment plots. Virginia Cooperative Extension recommendations were followed for production of the crop. Foliar applications of Orthene and Dipel were applied on 6 Jul with a CO2-pressurized backpack sprayer that delivered 30 gal/acre through 3 TX-12 tips at 60 psi. TA populations were estimated on the upper 4 leaves of 10 plants/plot about once a week from 5 to 11 wk after transplanting. On 25 Aug, TA damage was rated on a scale of 0 to 10 where 0 = no aphid damage or sooty mold and 10 = very severe necrosis of leaves and extensive sooty mold. TFB and TFB feeding holes in the most damaged leaf were counted on 10 plants/ plot. Tobacco was harvested as it ripened, weighed, graded by a USDA/AMS inspector, and yield and price were calculated. Data were analyzed by ANOVA and significantly different means were separated by WD (K-ratio = 100). Aphid count data were transformed to Log10(x + 1) before analysis.

AbstractTwo field trials were conducted on the Research Farm of the Institute of Food Security, Environmental Resources and Agricultural Research, Nigeria during the late cropping seasons (Jun.–Nov.) of 2014 and 2015 to evaluate the agronomic performance of four recently released sunflower varieties (SAMSUN-1, SMASUN-2, SAMSUN-3 and SAMSUN-4) to three fertilizer regimes: Control, Split application of 30 kg N + 28 kg P2O5 at 21 days after sowing (DAS) and at anthesis and Single application of 60 kg N and 56 kg P2O5 at 21DAS. The experiment was laid out in a randomized complete block design using a 3 × 4 factorial arrangement and replicated three times. Data were collected on phenology, plant height, seed yield and yield attributes, and quality. The varietal effect was only significant in 2015 for head weight, a number of achene per head and 100 achene weight. Application of N and P fertilizer either as split or single significantly (P ≤ 0.05; F-test) enhanced plant height at R5 and R9, 100 achene weight, achene weight per head and grain yield in both years. Single application resulted in significantly (P ≤ 0.05) higher grain yield in 2014 than the split and control and was on par with a split. Significant variety × fertilizer regime was recorded for protein content in 2014 and 2015, and oil content in 2015. Therefore, a single application of N and P fertilizers at 21 WAS is recommended for adoption in the humid tropics to enhance seed and oil production of SAMSUN-3 and SAMSUN-4.

A field experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during 2010-2011 to determine the effects and economic performance of urea super granule (USG) and prilled urea (PU) in terms of growth and yield of broccoli and to find out the optimum and economic doses of USG and PU for broccoli in Shallow Red-Brown Terrace Soil under Madhupur Tract. The experiment was laid out in a randomized complete block design with three replications having 17 treatment combinations constituted with different levels of urea super granule (USG) and prilled urea (PU). Result showed that yield of broccoli increased significantly with increasing rate of USG and PU. The treatments containing 160 kg N from USG and 180 kg N from PU exhibited the best performance on yield and yield contributing characters of broccoli having the head yield of 12.9 and 10.6 ton ha-1, respectively. All the yield contributing characters and the economic profitability were favorably correlated with these high yield performing treatments. The performance of USG in terms of growth, yield and yield attributes, head quality (compactness coefficient) and economic profitability was found significantly higher as compared to that of PU. Therefore, USG @ 160 kg N ha-1 and PU @ 180 kg N ha-1 alongwith other recommended fertilizerscould be suggested for broccoli production in terms of yield and economics. From quadratic equation USG @ 163 and 160 kg N ha-1 and PU @ 169 and 160 kg N ha-1 alongwith other recommended fertilizerscould be suggested as optimum and economic doses for broccoli production in Silty Clay Loam Soil of Madhupur Tract.The Agriculturists 2016; 14(2) 95-112

Annual Herb

Okra, Abelmoschus esculentus (L.) MOENCH, a fasting growing annual herb, cultivated for its young fruit and valued as an important vegetable in tropical and sub- tropical regions. Adequate production of okra is yet to be achieved especially in Anambra State due to certain factors such as non- utilization of improved cultivar, environmental conditions and inadequate cultural practices. Due to the importance of this vegetable to Nigerian diet, sustainable production is adequate to meet up with the increasing population and the country’s economic recession. Vegetative and yield attributes of five cultivars of okra were evaluated for adaptation in Anambra State during 2014/2015 cropping season at the Department of Agricultural Education Teaching and Research Farm, Nwafor Orizu College of Education Nsugbe, Anambra State. A randomized complete block design, replicated three times was used. The results were statistically analyzed using ANOVA. Results showed significant differences (P<0.05) among the cultivars evaluated in both vegetative and yield attributes. Cultivar LD-88 had higher yield when compared to other cultivars evaluated. It is therefore recommended to farmers for sustainable okra production in the study area.
