A field experiment was conducted in Sher-e-Bangla Agricultural University (SAU), Dhaka, Bangladesh during the period from November, 2017 to March, 2018 in rabi season to observe the effect of biochar on the yield and quality of potato tuber and to find out the optimum dose of biochar along with inorganic fertilizer for achieving the maximum yield of potato. The experiment consist of 9 treatments as Control (no chemical fertilizer and biochar), Recommended Fertilizer Dose; Recommended Fertilizer Dose+Biochar @ 2.5 t ha-1; Recommended Fertilizer Dose+Biochar @ 5.0 t ha-1; Recommended Fertilizer Dose+Biochar @ 7.5 t ha-1; 1/2 of Recommended Fertilizer Dose+Biochar @ 2.5 t ha-1; ½ of Recommended Fertilizer Dose+Biochar @ 5.0 t ha-1; ½ of Recommended Fertilizer Dose + Biochar @ 7.5 t ha-1; Biochar @ 10 t ha-1. The experiment was laid out in a Randomized Complete Block Design with three replications. The tested variety was BARI Alu-7 (Diamant). Data were collected on different yield attributes, growth and quality of potato and postharvest soil analysis. The results indicated that biochar application significantly (p<0.05) increased plant height, weight of tubers, yield of tubers, tuber dry matter content, tuber specific gravity, soil organic carbon. Results suggested that biochar application had significant positive effect on plant and soil.

A field experiment was conducted in Eastern Tigray, Ethiopia, during the summer season to determine the effects of flower removal and earthing up time on the tuber yield and quality of potato (Solanum tuberosum L.). The experiment comprised three flower removal stages and five earthing up time treatments, which were laid out in a randomized complete block design (RCBD) of a 5x3 factorial arrangement with three replications. Data collected on tuber yield and quality parameters were analyzed using SAS version 9.2. The interaction of flower removal stages and earthing up time treatments affected marketable and unmarketable tuber number and yield, total tuber number and yield, large-sized tuber weight, and number of large-sized tubers. The medium and small-sized tubers were also affected by main treatments but not by their interaction treatments. Similarly, dry matter content was significantly (p<0.05) affected by flower removal alone, but not by earthing up time and its interaction with flower removal. Generally, the highest marketable tuber yield (30.25 t ha-1), large-sized tuber weight (424.9 g), the number of large-sized tubers (5), and total tuber yield (30.96 t ha-1) were recorded in the treatment of potato flower removed at the bud stage and earthed up at 15 days after complete emergence. Therefore, the removal of potato flowers at the bud stage and earthing up at 15 days after complete emergence and common cultivation can be practiced for better tuber yield and quality of potato.

Growing Conditions

Brinjal is a crop grown widely all over India and preferred by both rich and poor. The Chhotanagpur plateau of Jharkhand is famous for quality vegetable production and brinjal is very commonly grown in this region almost throughout the year. However, the most of the commercial growers using plant protection chemicals and synthetic fertilizers those are so expensive that poor farmers can’t afford. The extensive uses of agro-chemicals and synthetic fertilizers also reduce the quality of both the produce and the cultivated soil. In this context, an attempt has been made through the present investigation by growing different varieties of brinjal by adopting Vedic (Enriched Sanjeevani) Farming and Homa Induction (Agnihotra) techniques with their respective four non-chemical alternative growing approaches, viz.  E1C1: Enriched Sanjeevani (1%), E1C2: Absolute Control (inherent fertility status of the experimental plot); E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra), and E2C2: Only Homa Induction (Agnihotra). Five varieties of the crop, viz. V1: Swarna Pratibha; V2: Swarna Neelima; V3: Swarna Shakti; V4: Mukta Jhuri; V5: Long Green were grown with their four replications under four growing conditions and the Randomized Completed Block Design was adopted for field trials. Different growth, yield and quality attributing characters of the crop were taken into account and findings revealed that E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra) was the most suitable growing condition for V2 (Swarna Neelima) with the maximum yield (72.37 t ha-1). Different growth and yield attributes of the crop varieties (especially in the case of V2: Swarna Neelima) were highly influenced by Enriched Sanjeevani (1%) + Homa Induction (Agnihotra) [E2C1] growing condition resulting higher benefit cost ratio of 6.78. Quality contributing attributes were also highly influenced by homa induction (Agnihotra), as a consequence, higher level of dry matter, TSS, and ascorbic acid contents were estimated from almost all samples collected from E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra), and E2C2: Only Homa Induction (Agnihotra) growing conditions.

A two-year experiment (2009-2010) included four potato varieties (Desire, Romano, Bistra and Kis Sora). Experiments were conducted in Butmir (about 500 m/ asl) and Glamoč (approximately 900 m/ asl) region. The aim was to select new varieties for our area of cultivation. Productive characteristics of potato varieties (yield, weight and number of tubers per box) were examined. In the frame of qualitative properties, dry matter content and starch were examined. Trials were performed by randomised block design with four replications, and the results were analysed using the analysis of variance. Higher average yield was achieved by Romano cultivar by 8% compared to Desire and Kis Sora. Dry matter content ranged from 21.80% in Romano to 22.20% in Desiree. Examining varieties should be continued in the upcoming period in order to determine the most favourable conditions for cultivation in the area of Bosnia and Herzegovina.

The experiment was conducted during March, 2016 to March, 2017 in a barojof experimental farm of Sher-e-Bangla Agricultural University, Dhaka. Thirteen betel vine cultivars designated as PB 001 through PB 013 were collected from different locations of Bangladesh and found remarkable variations in vegetative growth, morphological features, yield and yield attributes. The betel vine cultivars varied in vine elongation (37.46 – 50.34 cm per month), increase in internode length (6.75 – 10.08 cm per month) and vine girth (0.445 - 0.747 cm per year). The leaf length (17.13-27.35 cm), leaf breadth (8.33 - 16.20 cm), petiole length (4.83 -11.45 cm) and petiole breadth (0.47 - 0.28 cm) remarkably varied among the cultivars. Fresh weight of 100-petiole, 100-leaves, and dry matter content were 50.07 - 165.74 g, 289.38 - 565.25 g and 12.57 - 14.49%, respectively in different cultivars. Leaf number per meter vine (9.46 - 15.38) and leaf number per plant per year (50.16 - 78.44) were also varied among the cultivars. The highest annual per hectare yield was obtained from BARI Pan-1 (23.82 t) and PB 006 (23.46 t). Variations were also existed among the cultivars in vine colour, leaf colour, leaf shape, leaf tip, leaf softness and pungency of leaf of cultivars. No pungency of leaf was found in cultivars PB 006 (Misti pan). So, PB 006 (Misti pan) was seemed to be a better cultivar/ germplasm in respect of yield and quality of betel leaf.

A field experiment was conducted at Spices Research Sub-Centre (SRSC), Bangladesh Agricultural Research Institute (BARI), Faridpur, Bangladesh during the winter season of 2018-2019 to investigate the influences of transplanting times of seedlings and the varieties on the yield and quality of onion bulbs. There were six levels of transplanting time such as T1: November 15, T2: November 30, T3: December 15, T4: December 30, T5: January 14 and T6: January 29 under the trial. The varieties used in the study were: BARI Onion-1 and BARI Onion-4. The experiment was laid out in a randomized complete block design (RCBD) of factorial concept with three replications. The results revealed that dates of transplanting, varieties and their combined effects had significant effect on the parameters studied with minor exception. The plant height, number of leaves/plant and incidence of bolting were decreased with the passage of transplanting time. The maximum values (54.51 cm, 8.53 and 71.28%) of the aforementioned traits were recorded at early transplanting on November 15, respectively. The reduced percent of bolting (2.22%) was observed at December 30. While no incidence of bolting was found under transplanting on 14-29 January. Bulb diameter, individual bulb weight, yield, total soluble solid content and dry matter content of bulb were increased up to transplanting on December 15. Afterwards the values of aforesaid parameters were gradually decreased. The highest yield (17.65 t/ha), total soluble solid content (17.02 0brix) and dry matter content of bulb (15.95%) were obtained from December 15 insignificantly followed by December 30 (16.30 t/ha). The delayed transplanting on 29 January markedly reduced the yield (6.72 t/ha), total soluble solid content (12.58 0brix) and dry matter content of bulb (11.61%) as well. The variety BARI Onion-4 performed better in respect of yield and yield attributes but it showed inferior quality. The combined effect of December 15 x BARI Onion-4 gave the highest yield attributes and yield of onion followed by the combination of November 30 x BARI Onion-4 and December 30 x BARI Onion-4 while the values among the three treatments were statistically similar.

China is the origin and distribution center of kiwifruit, as well as the country with the largest cultivated area and output of kiwifruit. A previous study found that a new kiwifruit virus, Actinidia yellowing ringspot virus (AYRSpV), has been detected in kiwifruit samples with yellowed leaves. The incidence of this virus was high in kiwifruit plantings in Shaanxi Province. To determine the symptoms of this viral infection and the effects of this virus on the yield and quality of kiwifruits, we measured leaf chlorophyll levels and the fruit yield, total sugar, total acid and dry matter contents of ‘Hayward’ kiwifruits grafted with AYRSpV-infected scions. The results showed that after AYRSpV infection, symptoms including chlorotic ringspots were mainly observed in the spring and gradually recovered with high summer temperatures. A few of the leaves that did not recover showed symptoms of albinism, which lasted until the leaves fell. We found that AYRSpV infection could reduce the chlorophyll content of ‘Hayward’ kiwifruit by 74.61-76.64%, the fruit yield by 14.50-24.10%, the sugar to acid ratio by 50.09-50.57%, and the fruit dry matter content by 1.67-1.78%. Our results showed that AYRSpV infection could significantly affect the yield and quality of ‘Hayward’ kiwifruit.

Wood Residues

Intensive potato cropping has been reported as a major cause of degradation of sandy soils. Wood residues from tree clipping applied to soils can substitute for crop residues to maintain adequate organic matter levels and crop productivity. However, this ligneous material presents a C:N ratio varying from 50 to 175 and, when applied in large quantities, may induce N immobilization at the expense of the crop. The objectives of this study were to quantify the importance of this N immobilization following addition of residues and its effect on yield and quality of potato crops. Fresh or humified residues (50 t ha−1) were applied to the soil and incorporated. The third treatment received no residue. Each treatment was subdivided into subtreatments which received either 0, 150, 200 or 250 kg N ha−1. P, K, Mg and S were applied at the same rate on all treatments. Following the application of wood residues in 1987, 46 kg N ha−1 were immobilized in amended plots. N recovery from fertilizer was 51%. To obtain comparable yields of similar quality to those measured on unamended plots, an additional 1.9 kg N t−1 residues added or 100 kg N ha−1 were required. In 1988, N immobilization was considerably reduced; yield and quality of potato tubers in plots that received wood residues the previous year were comparable to those of the unamended plots with appropriate fertilization. Water retention was significantly improved in plots that received wood residues. Partial decomposition of the residues for 1 yr prior to application on the soil did not significantly improve plant growth compared to fresh residues. Key words: Wood residues, tree clippings, potato yield, dry matter content, nitrogen immobilization, soil water content

In the years 1995&ndash;1997 the effect of ecological growing on the yield and selected parameters of quality of consumer potatoes (in comparison with conventional way) were investigated. The ecological way of growing differed in the lack of chemical protection against diseases and pests and industrial fertilizers. Field trials were realised with seven varieties (Impala, Karin, Agria, Korela, Rosella, Sant&eacute; and Ornella) on two sites (Uhř&iacute;něves and Valečov). The ecological way of growing had markedly negative effect on the yield (decrease by 36%). In qualitative parameters the ecological way increased inconclusively polyphenol content (by 10.2%), decreased inconclusively nitrate content (by 11.0%) and reducing sugars (by 22%). It did not affect dry matter content, resistance of tubers to mechanical damage, table value and glycoalkaloid content. Variety Sant&eacute; achieved the best results from the point of view of the yield and majority of qualitative parameters among varieties. Qualitative parameters of ecologically cultivated potatoes were significantly affected by the year of cultivation.

An investigation was carried out to assess the effect of planting materials on physiological parameters, cassava mosaic incidence and yield of Cassava varieties viz. H-226 and CO.2 at the Department of Vegetable crops, Horticultural College and Research Institute, TNAU, Coimbatore during September 2010 to June 2011. The experiments were laid out in Factorial Randomized Block Design with four treatments and three replications in two varieties. The results revealed that the tissue culture plants were found be the best in virtue of its high leaf area index, net assimilation rate, dry matter content, tuber yield (26.33 t ha-1) and least incidence of cassava mosaic virus. Among the varieties, CO.2 showed less incidence of CMD. The tissue cultured plants may be recommended to farmers to reduce mosaic disease incidence and get maximum yield in cassava.

The effect of harvest period on the quality of storage roots and leaves of cassava cultivars was determined in an experiment carried out in a randomized complete block design with four replications in a split plot scheme, with five cultivars in the plots and ten harvest times in the subplots. The IAC 13 cultivar had the highest rate of dry matter accumulation in the storage roots and the Mico cultivar the lowest. The period of least dry matter content in the storage roots occurred later for the Fécula Branca, Mico and IAC 14 cultivars, and the minimum starch content in the storage roots occurred later for the Fécula Branca and Mico cultivars. In general, the IAC 13, IAC 14 and Fécula Branca cultivars had higher dry matter content in the storage roots, while higher starch content in the dry and fresh matter were obtained in the Fécula Branca cultivar. The crude protein content in the leaves decreased as the plant aged.
