Leaf Harvest

Beetroot (Beta vulgaris), commonly known as table beet, is used as a staple in the diet of many people through the consumption of the entire plant, leaf, and the root. The objective of this study was to assess the effects of nitrogen (N) application and leaf harvest percentage on the yield and quality of roots and leaves of beetroot. The treatment design was a randomized complete block design with five levels of N (0, 60, 90, 120, and 150 kg·ha−1) combined with three leaf harvest percentages (0, 30, and 50) and replicated three times. The first leaf harvest was initiated 35 days after transplanting (DAT) by removing the outer matured leaves and the second harvest occurred 80 DAT by removing all the leaves. The results showed increases in leaf and root yield with an increase in N application. Nitrogen application at 90 and 120 kg·ha−1 increased fresh leaf weight, leaf number, and fresh and dry root weight, including root diameter and length with the exception of leaf area which was significantly higher at 120 kg·ha−1 N. Magnesium and iron leaf content, and N root content were significantly improved by the application of 120 kg·ha−1 N. Leaf harvest percentage did not have a significant effect on leaf yield or leaf and root mineral content. However, dry root weight was significantly reduced by the 50% leaf harvest. Leaf harvest at 30% or 50% increased total protein content of the roots of beetroot, whereas an increase in N application decreased concentration of total proteins. Results demonstrate that leaf and root yield, as well as magnesium, zinc, and iron leaf content, increased with the application of 120 kg·ha−1 N, whereas 30% leaf harvest did not negatively affect root yield.

A varietal testing had been undertaken in Pematangsiantar regency, North Sumatra province, Indonesia in 2015-2016. The objective of the study was to determine the preference of cassava growers to the introduced varieties compared to the existing cassava varieties. Twelve cassava varities (UB1/2, UB1472, Adira1, Malang4, Cecekijo, Farsem, Gajah, Ketan Jabung, Caspro, Malaysia, Adira4, and Cikaret) were tested using a Randomized Block Design with four replications. The data were taken on aboveground characters and underground characters such as root number, root diameter, root length, root weight, and starch content based on factory criteria (A = 22%, B = 18%, C = 14% and D = 10% starch content). Results of the study indicated that Malang-4 had the highest root yield (49,830 kg ha-1) followed by Farsem variety (41,690 kg ha-1), and Malaysia Local variety (41,030 kg ha-1). The bitter taste of Malang 4 was an appropriate character to be developed as starch processing of cassava. Starch content is very important indigenous criteria for farmers and traders to know fairly about pricing in relation with starch content. The higher starch content coincided with higher root yield of Malang-4 is very interesting and will benefit the factory. There was no difference in factory price of cassava from farmers, although the starch content indicated different levels (B =18%, C=14% or D =10%). The Malang-4 could be introduced to the local goverment for being grown in a larger areas in the North Sumatera province.

A field experiment was conducted at Horticulture farm of Nepal Polytechnic Institute (NPI) Bharatpur-11, Chitwan to study the effects of different doses of vermicompost on growth, yield and quality of radish (Raphanus sativus L. cv. Mino Early) from January 2020 to March 2020. Five different doses (0 ton, 5 ton, 10 ton, 15 ton, and 20 ton per hectare) of vermicompost were taken as treatments and the experiment was replicated four times. The experiment was set up in Randomized Complete Block Design (RCBD). The result of the study showed that there was a significant effect of different doses of vermicompost on plant height, the number of leaves per plant, spreading of the plant, root length, root weight per plant, root diameter, and root yield at harvesting. The maximum plant height, the maximum number of leaves per plant and maximum plant spreading in radish plant on vermicompost application was recorded every 30, 45 and 60 days after sowing (DAS). The maximum root length (29.60 cm), maximum root diameter (36.27 mm), maximum root weight (191.8 g), maximum biomass weight (241.6 g/plant), maximum root yield (47.9 ton/ha), were recorded on applying 15 ton/ha vermicompost at 60 DAS. The control treatment showed the minimum vegetative growth and yield. Among the different doses of vermicompost, the overall performance of radish was found better in 15 ton/ha of vermicompost. Statistical analysis showed no differences among (5 ton, 10 ton, 15 ton, 20 ton per hectare of vermicompost) applications. Hence, 5 ton per hectare of vermicompost application will be best for radish production in Chitwan.

An experiment on effect of organic manure & mulching on the growth and yield of carrot was conducted at the farm of Sher-e-Bangla Agricultural University, Dhaka during the period from November 2017 to February 2018. The research consisted in Randomized Complete Block Design (RCBD) with three replications under a factorial arrangement (of two factors), with Four levels of organic manure, as the factor A and four mulches such as factor B. Organic manure and mulching influenced significantly (p=0.05) all the studied variables. In case of organic manure the maximum plant height (44.55 cm) root length (14.73 cm), root diameter (4.11 cm), root weight (124.50 g), root yield (24.90 t/ha) and marketable root yield (23.85 ton/ha) were recorded from O2 (Vermicompost) treatment. In case of mulches, maximum plant height (44.81 cm), root length (15.20 cm), root diameter (3.91 cm), root weight (117.85 g), root yield (23.57 t/ha) and marketable root yield (21.95 t/ha) found in M2 (Black polythene) treatment. And the combined effect of the highest root yield (29.06 t/ha) was obtained from O2M2 (Vermicompost + black polythene) and lowest (13.20 t/ha) from O0M0 (control). So, it can be concluded that 10 ton/ha vermicompost with black polythene mulch was the best for carrot cultivation. The highest gross return (Tk. 563200), net return (Tk. 446355) and BCR (4.82) were obtained from the treatment combination from O2M2  where the lowest gross return (Tk. 207800), net return (Tk.112755)  were obtained from O0M0 and lowest BCR (1.67) from O1M0.

AbstractThis study aimed at determining shoot and root characteristics of cassava as affected by root yield and the influence of soil moisture on vegetative growth and yield. Thirty cassava genotypes were evaluated for morphological and physiological characterization in three locations in Nigeria: Ibadan, Mokwa and Zaria. Randomized complete block design was used with four replicates. Studies on the pasting properties of the genotypes were also carried out. Data were collected on plant height, stem girth, stay-green ability, garri and fresh root weight. Genotypes differed significantly (P < 0.05) across and within locations for shoot and root characteristics. Across locations, genotype 011663 had the highest plant height (132.4 cm); 30572 had the largest stem girth (8.6 cm); and 010040 was the best stay-green (2.2). Genotype 011086 had the highest number of roots per plot (95.7), 950289 had the highest fresh root yield (24.3 t/ha), and 990554 had the highest percentage of dry matter (35.2). Trends in root yields across locations were Ibadan (28.9 t/ha), Mokwa (20.3 t/ha), and Zaria (8 t/ha). Five genotypes IITA-TMS-IBA950289, 010034, 990554, 011807, and 980581 had negligible interactions with the environment and so have broad adaptation and are considered stable; and two clones 011807 and 950166 were found to be the best for pasting properties. Breeding strategies that consider root size, total root number, harvest index, dry matter, with applications for household foods and industrial uses, will be an effective and efficient way to select genotypes for high yield.

Nitrogen is the most important nutrient for rice (Oryza sativa L) yields. This study aimed to evaluate the response of upland rice cultivars to N rate and application times in a randomized block design, in subdivided plots with four replications. The studied factors were five rice cultivars (BRS MG Curinga, BRS Monarca, BRS Pepita, BRS Primavera, and BRS Sertaneja), three application times (100 % at planting, 50 % at planting - 50 % at tillering and 100 % at tillering) and four N rates (0, 50, 100, and 150 kg ha-1). All cultivars responded to increased rates and different times of N application, especially BRS Primavera and BRS Sertaneja, which were the most productive when 50 % N rates were applied at sowing and 50 % at tillering. The response of cultivar BRS Monarca to N fertilization was best when 100 % of the fertilizer was applied at tillering.

Abstract Micro-nutrients especially zinc can not only increase the yield of sweet potato but can also improve the quality of tubers. Hence, experiments were carried out in 2015 and 2016 cropping seasons to determine the impact of various levels of ZnSO4 fertilizer on soil chemical properties, foliage and storage root yields and proximate qualities of sweet potato (Ipomoea batatas L.). The experiments consisted of 5 levels (0, 5, 10, 15 and 20 kg ha-1) of ZnSO4 fertilizer. These were arranged in a randomized complete block design and replicated three times. ZnSO4 increased (with the exception of P) soil chemical properties compared with the control. N, K, Ca, Mg and Zn were increased up to the 20 kg ha-1 ZnSO4 level in both years. ZnSO4 reduced P concentrations in soil as the level increased. For sweet potato performance, 5 kg ha-1 ZnSO4 fertilizer had the highest values of foliage yield (vine length and vine weight) and storage root yield. Using the mean of the two years and compared with the control, ZnSO4 fertilizer at 5 kg ha-1 increased storage root yield of sweet potato by 17.4%. On fitting the mean storage root yield data of the two years with a cubic equation, the optimum rate of Zn for sweet potato was found to be 3.9 kg ha-1 to achieve the maximum sweet potato yield. In this study, relative to the control, ZnSO4 fertilizer increased moisture and decreased the fibre contents of sweet potato. There were no consistent patterns of variation between the 5, 10, 15 and 20 kg ha-1 ZnSO4 treatments for proximate qualities except that the highest values of fat, protein, carbohydrate and ash was at 5 kg ha-1 ZnSO4.

Nitrogen management is critical for sugarbeet (Beta vulgaris L.) because N inversely influences root yield and recoverable white sucrose per tonne (RWST). From 2015 to 2017 in Ontario the use of optical sensors (SPAD, Greenseeker) was evaluated as a method to guide N application and harvest date (late-September, late-October) selection by predicting root yield RWST and partial profit margins. In a commercial field, fertilizer N rate (4, 5) and cultivar (8, 12) were tested in a split block design experiment with three replications and two harvest dates. In all years, few cultivars (≤2) had a root yield response to applied N, which was attributed to high inherent soil fertility and limited our evaluation of optical sensors to adjust in-season N applications. The optimal N rate to maximize RWST and profits was 0 to 45 kg N ha-1 and confirmed their negative relationship to applied N. Optical sensor readings correlated negatively with RWST across the majority (>60%) of cultivars tested in mid-August and September. Across all cultivars, the regression model of optical sensors to predict RWST at early harvest was strongest (R2=0.48 for SPAD; 0.24 Greenseeker) when readings were taken in early September. Although future research to refine this relationship is needed, we recommend the use of optical sensors, particularly the SPAD meter, in early September to guide harvest selection to maximize RWST.

In Brazil, inoculation with Bradyrhizobium japonicum strains is the main form of N assimilation by soybeans, but there are reports of the use of mineral N as a complement to the demand of this nutrient by the plant. The objective of this work was to verify the effect of different forms and times of N application on vegetative growth and soybean crop yield in northern Mato Grosso. The experimental design was a randomized block design (DBC) with 10 treatments: control (no N application); and in all other treatments 10 kg ha-1 of N was applied, changing season and form of application as: the haul in cover at planting; in V2 at hedging; in V2 via leaf; in V4 at hedging; of N in leaf V4; from N in R1 to hedging; N in leaf R1; in R2 at cover and in R2 leaf. The cultivar used was Bonus from Brasmax®. Vegetative growth was evaluated by height, stem diameter, shoot dry mass, nodulation by number of nodules and yield by variables, number of pods, grains per pod, mass of 1000 grains, and weight. productivity. In practically all variables analyzed, no effects of nitrogen application on soybean crop were verified. The shoot dry mass was higher when nitrogen was applied to V2 via foliar spraying and to V4 in soil cover. In general, although there was no statistical difference between treatments, N application at the beginning of crop development increased soybean yield. The application treatment V2 was the most productive, produced 34% more than the control without N, or 17.34 more bags than the control.

So far, research has been conducted to know the effect of cattle manure fertilizer on growth and yield of carrot under Jimma condition. Experiment was conducted at Jimma University College of Agriculture and Veterinary Medicine at horticulture garden during 2016 cropping season under irrigation condition. Experiment was laid out in randomized complete block design and cattle manure applications with four treatments (0, 5, 10 and 18 tons per hectare) were used. Each treatment was replicated three times. Data was collected from five randomly taken plants per plot. The finding revealed that application of cattle manure on carrot showed a highly significant effect for growth parameters (plant height, canopy diameter, root length and root diameter). Application of cattle manure at 10 tons ha-1 increased carrot root weight by 48.8 % compared to the non-fertilized control treatment. Therefore, this finding would be a base for future research to be conducted.
