A field experiment was conducted during the Kharifseason of 2012 to study the response of black gram (Vignamungo L. Hepper) to different spacing and fertilizer doses under rainfed conditions.Maintaining a wider spacing of 30×10 cm (S2) was found to increase uptake of nutrients P and K by the crop resulting in significantly higher number of leaves, branches and pods per plant respectively, thereby registering the highest grain and stover yields of 730 kg/ha and 1382 kg/ha respectively. Among the fertilizer dose, F2 (N10P40K20 + FYM@ 5 t/ha) was found to increase theavailability of NPK by the crop resulting in significantly superior growth attributes viz., plant height, number of leaves and branches/plant and leaf area index (LAI) ultimately recording maximum number of pods/plant, test weight and grain yield of 725 kg/ha. Whereas, the fertilizer dose F3 (N20P50K30) was found to record the highest stover yield of 1362 kg/ha.

A field experiment was conducted to find out the effect of phosphorus, sulphur and PSB on growth attributes and yield of Vigna radiata. The experiment consisted four levels of phosphorus (0, 20, 40 and 60 kg h-1) and three levels of sulphur (0, 20, and 40 kg h-1) and seed non-inoculated and inoculated with PSB. Increasing level of phosphorus up to 60 kg ha-1 and sulphur up to 40 kg ha-1 gradually increases the plant height and significantly increases the number of pod plant-1, number of grain per pod-1, grain yield h-1 and stover yield. Seed inoculated with PSB showed superior plant height, significantly increases the number of pod plant-1, number of grain per pod-1, grain yield h-1 and stover yield. In similar proportion net return also increased with increase in the level of phosphorus, sulphur and seed inoculation with PSB.

SUMMARYNitrogen is an important factor determining grain yield of barley (Hordeum vulgare L.). Optimal rates and application timing can vary according to the environmental conditions under which the crop is grown. For 8 years (1979–86) barley yield, tillering, and leaf-area response to N application rates and timing were studied in southern Spain. The results showed that, under our experimental conditions, the most advantageous N rate for grain yield was 60 kg/ha, either split equally between sowing and tillering, or else with the greater proportion applied at tillering. Nitrogen applied at sowing increased number of tillers per plant, and N applied at tillering favoured tiller survival for later spike formation. In addition, N applied at tillering increased the number of leaves per plant, leaf area per plant, and the leaf area index, the maximum value of which occurred at anthesis.

An experiment was conducted during December, 2017 to May, 2018 at the Agronomy field of Sher-e-Bangla Agricultural University, Dhaka to evaluate the performance of white maize variety under different spacing and integrated fertilizer management. The experiment comprised two different factors; (1) two plant spacing viz. S1 (60 cm × 20 cm) and S2 (40 cm × 20 cm) and (2) four levels of integrated fertilizer application viz. T1: All chemical fertilizer (recommended dose), T2: maize straw compost +½ of recommended dose,T3: cowdung+½ of recommended dose and T4: vermicompost +½ of recommended dose. The experiment was set up in split plot design with three replications. Results revealed that both the individual and the interaction treatments had effect on different growth and yield parameters of white maize. In respect of the spacing effect, the wider spacing S1 showed higher plant height, number of leaves plant-1, cob length, cob circumference, number of grains cob-1, shelling percentage, 100 grains weight and harvest index where S2 showed higher grain yield. The integrated fertilizer had significant effect on different growth and yield parameters of white maize. In respect of the integrated fertilizer effect, the highest values in plant height, number of leaves plant-1, leaf area index and crop growth rate, cob length, cob circumference, number of grains cob-1, shelling percentage, 100 grains weight, grain yield, stover yield and biological yield were highest with T3 whereas, the lowest corresponding values were recorded from T2. Among the interaction treatments, higher seed yield was obtained with the interaction treatment S2T3 (10.01 t ha-1) while S1T2 showed significantly the lowest seed yield (5.27 t ha-1). The highest seed yield was mostly attributed to the number of grains per cob (328-433) and 100 seed weights (29.67-33.33 g).

Yield Formation

The Finnish growing season is particularly short, with an intensive growth period, unfavourable rainfall distribution and frequently occurring fluctuations in climate that affect crop growth and yield formation. A three-year study was conducted in the field to determine the contribution of alterations in canopy structure, tillering and stem elongation among dwarf (D), semidwarf (SD) and tall (T) oat (Avena sativa L.) lines to yield formation. Yield components, leaf characteristics and straw traits were measured from six oat lines (D lines Pal and Grane, SD lines Hja 76416 and Salo, and T lines Veli and Jalostettu maatiainen) separately on the main shoot and tillers. Results indicated that long leaf area duration and high leaf area index were associated with increased grain yield probably due to more persistent and active assimilation. Also, higher number of leaves increased the grain yield. Higher peduncle, straw and node weights associating with increased grain yield may result from more abundant assimilate reserves; however, the longer the straw and peduncle, the lower the grain yield, which may result from increased lodging of SD and T lines. The traits contributing most to the grain yield varied greatly from year to year. It is concluded that no single dominant trait determined grain yield, since yield is a product of several different traits. SD lines seemed to be most promising for further breeding programs on the basis of their growth pattern and yielding ability.;

A 2 x 3 factorial experiment was conducted in cropping season at the old Teaching and Research Farm, Federal University of Technology, Minna, to determine the effect of land configuration and crop residue – mulch on the growth and yield of millet in Minna, Southern guinea savanna zone of Nigeria. It was a randomized complete block design with two types of land configuration (ridge and flat surface) and three mulch application rates (0, 10 and 15 t/ha), replicated three times. Composite soil samples were collected from the experimental site at 0 – 15 and 15 – 30 cm depths prior to the commencement of this study, for the determination of initial soil physicochemical properties. Crop growth parameters measured were plant height, number of leaves per plant, number of tillers per plant and leaf area index at 3, 6, 9 and 12 weeks after planting. Yield indices determined were panicle length and stover yield. Data collected were subjected to analysis of variance at 0.05 level of significance, while means separation was done using Duncan’s multiple range test. Findings in this study showed that planting on ridge resulted in taller (P ≤ 0.05) millet plants and a higher number of leaves per plant, a higher number of tillers per plant and higher leaf area index than planting on the flat. Plant height, the number of leaves per plant, the number of tillers per plant, leaf area index, panicle length and stover yield increased with increasing mulch application rates.

The Alfisols of Makurdi Local Government Area of Benue State was studied with the aim to characterize and classify the soils and determine the optimum fertilizer rate for maize production on the selected soil type of the study area. The soils were formed on Makurdi sand stone, deep (141 cm) and well drained. They were coarse-textured and moderately acidic in reaction (pH 6.6 – 7.0). They had low organic carbon contents ranging from 3.36 to 3.78 % and high base saturation of 58.6 % to 77.4 %. Based on the physical and chemical characteristics, the soils were classified as Eutric Ochrustalfs/Eutric Luvisols. In terms of growth parameters; plant height and number of leaves were not significantly different while leaf area, leaf area index and the stem diameter were significantly different. The highest (130.60 cm, 12.30 and 79.88 mm) plant height, number of leaves and stem diameter were observed at the rate of NPK 150:75:75 kg/ha of fertilizer. In terms of yield parameters, ear weight and grain yield were not statistically significant whereas, ear length and ear diameter were statistically significant. However, NPK 60:30:30 kg/ha showed the highest (178 g) ear weight while application of NPK 150:75:75 kg/ha gave the highest (2.82 kg) grain yield. Since there was no significant difference between the fertilizer rates, it could be concluded that the minimum application rate (NPK 60:30:30 kg/ha) should be used in cultivating maize in Alfisols of Makurdi instead of the highest or the blanket recommendation which involved higher cost.

A field experiment was conducted in 2018 and 2019 seasons at the Teaching and Research Farm of the Federal University of Technology, Minna to determine the varietal response of maize to nitrogen and zinc fertilizer in Minna. The treatments included four levels of N: 0, 30, 60 and 90 kg ha-1, three levels of Zn: 0, 2.5 and 5 kg ha-1 and two varieties of maize (Oba Super 2 and Suwan-1-SR). The experimental design was a 4×3×2 factorial design fitted in a randomized complete block design with three replications. The data collected were, plant height, number of leaves, cob weight, cob length, stover yield, grain yield and 1000 grain weight. All data collected were subjected to analysis of variance and the means were separated using Duncan Multiple Range Test. Highest plant height (43.69 and 44.37 cm) were obtained in 60 and 90 kg N ha-1 treatment application respectively in year 2018 at 3 Week After Sowing (WAS), these heights were significantly different from that of control (0 kg N ha-1). Zinc (Zn) fertilization has no significant effect on maize height at all growth stage of maize in year 2018. Application of Zn produced significantly taller plants than those without Zn application at 3 and 9 WAS in 2019. The treatment 60 kg N ha-1 had significantly higher yield (27873.7 kg ha-1) than others but similar to 90 kg N ha-1 (2512.4 kg ha-1). Application of 60 kg N ha-1 increased with 12 % than the 0 kg N ha-1 on maize yield in 2019. There was response to Zn fertilization on stover and grain yields. The interaction effects were significant on stover yield. The nitrogen rate of 60 kg N ha-1 and the zinc rate of 2.5 kg were optimum for maize grain yield in Minna, both Oba Super 2 and Suwan-1-SR performed better in the study.

Durum Wheat Cultivar

The threat of land degradation by salinization in Jordan has been increasing over the last decades. Therefore, information about the response of local cultivars to salinity is needed to help farmers choose the most productive cultivars for areas with salt-affected soils. A recently released durum wheat cultivar Um Qais (Triticum turgidum subsp. durum) has shown to be productive under normal conditions but to date there are no known studies on its tolerance to salinity. Two experiments were conducted to investigate the response of Um Qais cultivar to salinity. A field experiment was carried out in the Jordan Valley, which is known for its hot, dry climate during the summer and low rainfall and moderate temperature during the winter. Three water salinity levels (S): S1 (2 dS m−1), S2 (4 dS m−1), and S3 (8 dS m−1) with three irrigation amounts (R) (control = 120% (R1), 100% (R2), and 70% (R3)) were used in the field. A greenhouse experiment was conducted using four levels of saline water (S): S1 (0.65 dS m−1), S2 (4 dS m−1), S3 (8 dS m−1), and S4 (10 dS m−1). In both experiments, the leaf area index (LAI) and canopy height were measured during three growth stages, tillering, flag leaf, and maturity. The number of grains, grain yield, and above-ground biomass were measured after harvesting while soil salinity and pH were measured every three weeks during the growing season. The results showed that the maximum reduction in yield was of the 28% in the field experiment when the average soil salinity was of 6.8 ± 1.1 (standard error) dS m−1 at the middle stages of the season. Significant changes were shown in the treatments of the field experiments for maximum LAI, number of grains, and aboveground biomass, but not for plant height. For the greenhouse treatments, about 60% of the maximum grain yield was obtained when the average soil salinity was 9.94 ± 1.89 dS m−1 at the middle stage. Grain yield was the most sensitive parameter to the increase in soil salinity during the season. According to the findings of both experiments, Um Qais can be cultivated in moderately saline soils.
