The investigation was carried out to evaluate the effect of different organic manures on turmeric with reference to vegetative growth, biomass production, rhizome yield and its attributes of turmeric (Curcuma longa L.). Turmeric showed better response to the application of organic manures. Plant with neem cake application had the taller plant (79.30 cm), maximum number of tillers per plant (5.40), leaf number (5.40), leaf area (44.09) leaf area index (0.429), fresh weight of halum ( 190.05g), fresh weight of root (49.13 g), fresh weight of rhizome per plant (256.21 g) and dry weight of halum (15.21g), dry weight of root (7.32 g), dry weight of rhizome per plant (40.35 g), total dry matter yield (6.85 t ha-1) than those received other types of manures. Moreover, yield attributes such as number of mother rhizomes per plant-1 (1.75), more number of primary rhizomes per plant-1 (5.19), secondary rhizomes per plant-1 (18.03) and tertiary rhizomes per plant (7.69) were also highly accelerated by neem cake application. Similarly, the same treatment expressed the best in terms of size of mother rhizome (7.69 cm), primary rhizome (21.86 cm) and secondary rhizomes (7.05 cm).All these parameters in cumulative contributed to  produce the highest estimated fresh rhizomes yield & cured rhizomes yield (29.48 t ha-1, 5.59 t ha-1 respectively). The highest curing percentage (20.28) was observed in T3 treatment having mustard cake@ 2.0 t/ha. Thus, organic manure like neem cake was best fitted natural fertilizer for turmeric cultivation.DOI: http://dx.doi.org/10.3329/agric.v10i1.11060The Agriculturists 2012; 10(1): 16-22

Organic Manures

A pot experiment was carried out in the net house of the Department of Soil, Water and Environment, University of Dhaka to evaluate the effectS of different organic manures on the growth performance, biomass production, NPKS content in leaf, stem and root of Burmese grapes (Baccaurea ramiflora) and some chemical properties of post- harvest soil. Two-month old Burmese grapes seedlings were planted in different organic manure-treated soils (viz. ACI, BGF, Bhola, Green Life, Kazi, Modern, Mazim, Payel, Payel Earth, and Shebok). A significant variation was observed among the treatments. Compared to control treatment, application of organic manures exhibited a significant influence on the physiological growth, viz. plant height (30.4 - 34.06 cm), leaf area (64.2 - 71.30 cm2/plant), leaf area index (0.17 - 0.19), fresh weight (32.2 - 53.06 g/plant), and dry weight (22.09 - 41.24 g/plant) after 120 days of the experiment. The highest plant height, leaf area, leaf area index, fresh weight, and dry weight were recorded in Kazi, BGF, Payel and Payel Earth, respectively. Similarly, the concentrations of N, P, K, and S in leaf, stem and root, and their uptakes were found significantly higher than the control. The highest N, P, K and S uptake by leaf, stem and root ranged from 37.66 - 41.69 kg/ha, 0.70 - 0.92 g/ha, 66.19 - 84.926 kg/ha and 6.82 - 10.11 kg/ha, respectively. Protein content was the highest in Payel in leaf (8%) and root (5%), and stem (7%) in Modern manure treatment. The overall results revealed that Kazi and Payel manures might be better for raising strong and healthy Burmese grape seedlings. J. Biodivers. Conserv. Bioresour. Manag. 2021, 7(1): 63-72

Despite the existing several Sugar manufacturing companies in Sudan, there is an acute shortage in sugar supply, therefore the government imports Sugar to bridge the gap. One of the strategies to be followed is the introduction of Sugar beet (Beta vulgaris) crop, mainly for sugar production. This crop has several advantages over Sugarcane such as short duration, less water requirement, in addition to other uses like animal feed. Therefore it became necessary to have good understanding of agricultural operations, cultural practices and adaptation. However, the main objective of this study was to assess the effect of Nitrogen fertilizer and plant spacing on vegetative growth of Sugar beet. This study was conducted at the farm of the College of Agriculture, University of Bahri, Alkadro, Khartoum State-Sudan; during the season 2016/2017. The experiment was arranged in Split plot in Randomized Complete Block Design with six treatments and four replications. Two plant spacing (15 and 20 cm.) were used as main plot, referred as (S1, S2) along with three levels of Nitrogen fertilizer (40, 80 and 120 kg/ha.), as subplot; referred as (N1, N2 and N3) and the control (0). Data regarding leaf number, leaf area index (LAI), leaf dry weight (g) (LDW), root diameter (mm.) and root fresh weight were recorded and statistically analyzed. The results showed S2 (20 cm) increased all the studied plant characters, namely the leaf number (29.139), leaf area index by (7.54), leaf dry weight (g) to (89.870), root diameter (mm) (94,992), root fresh weight (g) (695.80) compared to S1(1015 cm). On the other hand; the application of N3 (120 kg/ha.) increased the lead number (30.956), leaf Area Index (8.841), Leaf dry weight (102.47), root diameter (97.955) and root fresh weight (851.77) compared to S2 and S1 as presented in (table 4, table 5 and table 6).

A research on growth and yield components of some turmeric varieties (Curcuma longa L.) as affected by inorganic fertilizer levels in Umudike, South Eastern Nigeria was carried out at the teaching and research farm of the University, during 2018/2019 cropping seasons. It was laid out in a split plot design with three replications. Results, showed that plant height and number of tillers for both varieties and fertilizers levels increased at 2, 4, and 6 months after planting (MAP) during 2018 and 2019 cropping seasons. Variety 021 and 400 NPK (15:15:15) Kg-1 produced tallest plants and highest number of tillers over other varieties and fertilizer levels. Crop growth rate was positive at 2 – 4 MAP and negative at 4 – 6 MAP, with 021 and 400 NPK (15:15:15) kgha-1 producing higher growth rate. Heaviest rhizomes fresh weight (kg plot-1) of 3.74 and 3.75, rhizome dry matter content of 14.49 and 16.8%, rhizome dry weight of 23.57 and 23.90g and harvest index of 2.60 and 2.70% was yielded by UMT 021 variety over other varieties. The level of 400 NPK (15:15:15) kg ha-1 produced heaviest rhizome fresh weight of 4.47 and 4.57 kg plot-1; rhizome dry matter content of 19.42 and 25.8%; rhizome dry weight of 27.54 and 27.8g and harvest index of 2.81 and 3.20%, over other levels. Consequently, variety 021 and 400 NPK (15:15:15) kgha-1 are recommended for sole production of turmeric in Umudike, South Eastern Nigeria.

Field experiments were conducted over 4 years to evaluate the effects of antitranspirant (Folicote, Aquatrol Inc., Paulsboro, N.J.) and polyacrylamide gel (SuperSorb, Aquatrol Inc., Paulsboro, N.J.) on early growth of transplanted muskmelon grown either protected by tree windbreaks or exposed to seasonal winds. A randomized complete block design (RCBD) with split plot arrangement was used with wind protection (sheltered and exposed) areas as the main treatment and use of an antitranspirant spray or gel dip as subtreatments. Based on destructive harvests in the field, treatments and subtreatments did not affect dry weight or leaf area index in the first 2 years. Specific contrasts, however, showed that gel application significantly increased fresh weight, dry weight, and leaf area index over that of the untreated transplants whereas the spray application tended to reduce these factors during the first 3 weeks after transplanting. Significant differences between gel and spray subtreatments disappeared by 5 weeks after transplanting. Shelterbelts ameliorated crop microclimate thereby enhancing plant growth. Significantly, wind velocity at canopy height was reduced 40% on average and soil temperatures were about 4% warmer in the sheltered plots compared to the exposed plots during the first 5 weeks post-transplant. Muskmelon plants in the sheltered areas grew significantly faster than the plants in the exposed areas in 2 of the 3 years reported, with the 3-year average fresh weight increased by 168% due to wind protection. Overall transplanting success and early growth were enhanced the most by wind protection, followed by the polyacrylamide gel root dip, and least by the antitranspirant foliar spray. We conclude that microclimate modification by wind speed reduction can increase early muskmelon plant growth more consistently than the use of polyacrylamide gel as a root dip at transplanting or the use of an antitranspirant spray. A polyacrylamide gel root dip generally will provide more benefit during early muskmelon growth than the use of an antitranspirant spray.

Sugar beet is one of the sugar crops which widely grown in different regions of the world due to its advantages over Sugarcane. Several studies were conducted in Sudan to assess its adaptation and economic value. However, the aim of this experiment was to study the effect of application of compost and different levels of phosphorus fertilizer and their combination on Sugar beet (Beta vulgaris) growth attributes, yield and yield components. The study was conducted during the winter season 2018 –2019 at the farm of the College of Agriculture, University of Bahri, Alkadaro-Khartoum State, Sudan. The experiment was arranged in Randomized Complete Block Design (RCBD) with three replications and six treatments, namely the Compost (5t./ha.), Phosphorous (P2O5) (88kg./ha.), P2O5 (176 kg./ha.), Compost (5t./ha.)+P2O5 (88kg./ha.), Compost (5t./ha.)+ P2O5 (176Kg./ha.) and the Control (C) respectively. All cultural practices were carried out timely according to the recommendations of the Agricultural Research Centre in Sudan. Then the data pertaining the following agronomic traits were recorded, the leaf number; leaf dry weight (g), leaf area index (LAI) (cm), root diameter (RD) (cm) and root fresh weight (RFW) (g). The results of statistical analysis revealed the application of compost in combination with phosphorus displayed significant increase at 5% level for the leaf number (22.75), leaf area index (5.23), leaf dry weight(36.78), root diameter(69.67) and root fresh weight (422.68), followed by the application of compost alone compared to the control and other treatments. The study concludes that the combination of compost and mineral fertilizer (P2O5) proved to increase all Sugar beet growth and yield parameters.

Nitrogen (N) is an important nutrient for melon (Cucumis melo L.) production. However there is scanty information about the amount necessary to maintain an appropriate balance between growth and yield. Melon vegetative organs must develop sufficiently to intercept light and accumulate water and nutrients but it is also important to obtain a large reproductive-vegetative dry weight ratio to maximize the fruit yield. We evaluated the influence of different N amounts on the growth, production of dry matter and fruit yield of a melon 'Piel de sapo' type. A three-year field experiment was carried out from May to September. Melons were subjected to an irrigation depth of 100% crop evapotranspiration and to 11 N fertilization rates, ranging 11 to 393 kg ha-1 in the three years. The dry matter production of leaves and stems increased as the N amount increased. The dry matter of the whole plant was affected similarly, while the fruit dry matter decreased as the N amount was increased above 112, 93 and 95 kg ha-1, in 2005, 2006 and 2007, respectively. The maximum Leaf Area Index (LAI), 3.1, was obtained at 393 kg ha-1 of N. The lowest N supply reduced the fruit yield by 21%, while the highest increased the vegetative growth, LAI and Leaf Area Duration (LAD), but reduced yield by 24% relative to the N93 treatment. Excessive applications of N increase vegetative growth at the expense of reproductive growth. For this melon type, rates about 90-100 kg ha-1 of N are sufficient for adequate plant growth, development and maximum production. To obtain fruit yield close to the maximum, the leaf N concentration at the end of the crop cycle should be higher than 19.5 g kg-1.

The productivity of crops is highly affected by the seedling quality, which is governed by seeding density in the nursery. So, an experiment was conducted to explore the effect of seedling spacing in the growth attributes of Broad Leaf Mustard cv. “Marpha Chauda Paate” at IAAS, Lamjung Campus, during Oct 2018. Four spacing treatments viz 0.5 cm × 1 cm, 1 cm × 1 cm, 1.5 cm ×1.5 cm and 2 cm × 2 cm were arranged in RCB Design with 5 replications. Observation of seedling height, leaf area, leaf number, shoot & root fresh weights, shoot dry matter, and dry matter percentage from twenty-three days old seedlings were recorded.  The total leaf area was estimated using the Image-J package. Data were tabulated in MS Excel and analyzed by Gen Stat. Treatments differed significantly in seedling height, shoot and root fresh weight, leaf area, root length, and shoot dry weight, while the number of leaves and dry matter percentage did not differ statistically. Maximum shoot fresh weight (1.09 g), shoot dry weight (0.11 g), leaf area (48.24 cm2), root length (4.89 cm), root fresh weight (0.03 g) per plant and shoot dry matter percentage (9.24%) were found in widest spacing (2 cm × 2 cm). However, seedling height was recorded higher in closer spacing. Therefore, the study of the overall characteristics asserted that the seed spaced at 2 cm × 2 cm produced superior seedling over all other spacings. Int. J. Appl. Sci. Biotechnol. Vol 8(1): 65-70

Dry weight, leaf area, light interception and canopy photosynthesis were measured during 3- or 5-week regrowth periods of Setaria anceps/Desmodium intortum swards cut to 7.5 or 15 cm. Dry matter production during the experiment and over the growing season increased with cutting height and with interval between defoliations, but the proportion of grass to legume was unaffected. These effects of defoliation on dry matter production were similar to those estimated for integrated canopy photosynthesis from measured light interception and calculated leaf photosynthetic characteristics. Height and frequency of defoliation had no effect on canopy extinction coefficient for light, nor on the leaf photosynthetic characteristics, except for the first 1-2 weeks after defoliation when leaf photosynthetic rates appeared to be depressed. The main effects of height and frequency of defoliation on dry matter production were through their effects on leaf area index and light interception.
