Oyster mushroom (Pleurotus ostreatus) is the second most cultivated edible mushrooms worldwide after Agaricus bisporus and has more economic, ecological values and medicinal properties. Huge amounts of ligno-cellulosic agricultural crop residues by-products rich in organic compounds are annually generated. This study was conducted to compare effects of different agro residues on growth and bioconversion efficiency of oyster mushroom. P. ostreatus was cultivated on different treatment substrates viz., corn sheath + corn cob + coir pith (T1), paddy straw + ragi straw (T2) and sugarcane bagasse (T3) supplemented with 10 % wheat bran. Parameters such as spawn run days, primordia formation (days), harvest days, total yield and biological efficiency were evaluated. The best substrate was found to be T2 (paddy straw + ragi straw) in terms of spawn run (28 days), primordia formation (30 days), average number of fruiting bodies (108±1.3), stem length (7 cm) and cap diameter (9.5±0.085 cm). Total yield of P. ostreatus on different treatment substrates T1, T2 and T3 was found as 507±5 g, 317.7±3.1 g and 761±7.5 g, respectively. The biological efficiency of P. ostreatus was found high in T2 (92.08±0.89 %) followed by T3 (87.39±0.85 %) and T1 (72.37±0.7 %).

The aim of this research was to investigate the effect of variations in filler types, the amount of fillers and their interactions on the characteristics of bio-plastic composites from modified cassava starch-glucomannan, and determine the type and amount of fillers that produce the best bio-plastic composite characteristics of modified cassava starch-glucomannan. This research applied a randomized block design with factorial experiments using two factors consisted of the type of filler (ZnO, CMC and chitosan) and the amount of fillers (0, 0.2, 0.4, 0.6, 0.8 and 1.0 g), with the total of 18 combination treatments. Each combination treatment was grouped into 4 based on the processing time of making bio-plastic composites. The variables observed were tensile strength, elongation at break, Young’s modulus, swelling, degradation time of bio-plastic composites, surface profiles using scanning electron microscopy (SEM) and functional groups using FTIR spectrometers. The results showed that the type, the amount of fillers and their interactions had a very significant effect on tensile strength, elongation, Young’s modulus, swelling, and degradation time of bio-plastic composites from modified glucomannan cassava starch. Bio-plastic composites from modified cassava-glucomannan starch using ZnO with the addition of 0.6-1.0 g had the best characteristics compared to others with tensile strength values reaching 2012.45-2022.23 MPa, elongation at break 8.12-8.65 %, Young’s modulus 23.265.32-24,904.31 MPa, swelling 9.52-9.72 %, and degradation time of 6.25 days. Transverse surface profiles showed a smooth wave surface, there were not any holes or pores and visible fibers, while longitudinal surface profiles showed a fewer holes or pores and more smooth surface with not too high waves. In addition, these bio-plastic composites contained functional groups (O-H) and (C-H).

Geranium is an economically important aromatic plant for its highly priced essential oil. The essential oil yield and composition is influenced by genetic, agronomical and environmental factors but at maturity, the right harvesting time during the day without affecting the quality is not clear. Present study was undertaken to study the change in essential oil yield and composition at different harvesting time during a day in three geranium cultivars i.e., Bourbon, Bio-G-171, and CIM-Pawan. Randomised samples from three cultivars were harvested at crop maturity stage to obtain oil yield and composition of essential oil at different times (06 A.M., 10 A.M., 02 P.M., and 06 P.M.) during the day. Results indicated that essential oil yield increased significantly from 06 A.M. (0.18 %) to 06 P.M. (0.40 %) in Bourbon only and not in Bio-G-171 and CIM-Pawan. With respect to quality of essential oils, no significant quantitative variations in marker compounds was recorded. Citronellol/geraniol ratio is a quality criteria as per industry need and results unveiled high ratio in Bourbon (1.85) and CIM-Pawan (1.73) in afternoon and in Bio-G-171 (1.78) during forenoon, compared with other harvesting time during the day. The study revealed that essential oil significantly increased in cultivar Bourbon during the day but not in Bio-G-171 and CIM-Pawan cultivars. With respect to quality, considering C/G ratio, one can go for harvesting in cultivar Bourbon and CIM-Pawan in the afternoon and for cultivar Bio-G-171, harvesting in forenoon is advisable.

Jammu and Kashmir, the northern most state is one of the most important apple producing states of India. The pesticide trade has increased tremendously in the region which affects both environment and human health. This paper presents and estimated the cost of illness resulting from pesticide-related acute health symptoms in the apple growing region of Jammu and Kashmir. Apple growers reported as many as 15 serious issues and symptoms associated with the use of pesticides in the region. The study employs CobbDouglas linear production function, Cost of Illness method and Contingent valuation method through Willingness to Pay for analysing the requisite data. The study reveals that pesticide sprays and chemical fertilisers contribute 17.25 and 24.23 per cent to the overall apple production in the region. There is a decrease of 7.72 per cent cost of illness if the respondent who applies pesticides is a male and similarly, age of the respondent is having 0.35 per cent impact and incurs huge cost for the illness due to exposure. Similarly, household willingness to pay (WTP) for safer pesticides states that highly qualified respondents in the area are ready to pay 63.59 percent more than the less qualified/illiterate respondents.

Value addition of fresh tender jackfruit (Artocarpus heterophyllus L.) for vegetable purpose has gained much popularity due to its inherent nutritional and health benefits. For industries involved in value addition of tender jackfruit, rapid characterization of raw material is essential for screening and routine quality evaluation. But, conventional reference methods of quality evaluation are not suitable as they involve the use of chemicals, expensive, laborious and time consuming subject to the number of samples to be analyzed. As a promising alternative, the present study examined the performance of near-infrared spectroscopy (NIRS) as a novel approach to estimate pH, total soluble solid, titrable acidity, firmness and toughness of tender jackfruit. Partial least square regression (PLSR) models were used to establish linkage between reflectance spectra (1100-2450 nm) and quality attributes of fresh tender jackfruit. Based on residual prediction deviation (RPD) criteria, accuracy of PLSR model of titrable acidity was noted to be excellent (RPD=3.96) while good estimation was possible in case of firmness-tendril (RPD=2.61). Accuracy level suitable for coarse quantitative estimation (RPD=2.12) was noted in case of total soluble solids. The PLSR models of all other attributes were found to be capable of discriminating their low and high values (1.5

In vitro micropagation of banana is nowadays pinned towards development of disease free clones. An efficient protocol has been developed for micropropgation of banana cv. Poovan by using shoot tip as explant. The explants were cultured on Murashige and Skoog (MS) medium containing different concentrations of benzyl amino purine (BAP) and thidiazuron (TDZ) for the development of shoots and inodole butyric acid (IBA) for root induction. MS medium supplemented with TDZ was found to be effective for shoot multiplication than MS medium supplemented with BAP. The highest average number of shoots (7.1) for each explant was found in MS medium containing 1.0 mg L-1 TDZ, while, the maximum of five shoots were produced per explants in MS medium containing BAP (3 mg L-1). The result of this study showed that the maximum multiplication of shoots (8) was obtained in MS medium containing BAP (3 mg L-1) and TDZ (0.5 mg L-1) with four successive subcultures. Shoot elongation was found to be the best in MS medium containing GA3 (0.4 mg L -1). The well-developed shoots were transferred to the rooting media after three to four subcultures. More number of roots were produced in the medium having IBA (1.0 mg L-1). Rooted plantlets were successfully transferred to plastic pots containing autoclaved garden soil, farmyard manure and sand (2:1:1) for hardening. Regenerated plantlets successfully established in field and showed morphological characters identical to mother plants with success rate of 90 per cent. These findings suggested that the protocol might be used for commercial production of disease free Poovan clones through micropropagation.

The quality of agricultural production and their modulation by fertilizer application has increasingly received attention. However, the importance of magnesium (Mg) as an essential plant nutrient is well established, but its application has not been studied extensively specially in cherry tomato. The experiment was carried out during two successive seasons of 2018 and 2019 in polyhouse under ventilated condition to evaluate the effect of different Mg levels on growth, yield and fruit quality of cherry tomato grown under drip irrigation system. Foliar application of magnesium sulphate was done at three levels (0.2, 0.3 and 0.4 %) on three cultivars viz., Punjab Red Cherry, Punjab Kesar Cherry and Punjab Sona Cherry during vegetative stage at different time interval (at the first fortnight of January, February and March). The vegetative growth, yield and important quality traits of different cherry tomato cultivars, including TSS, titratable acidity were determined. Punjab Kesar Cherry cultivar showed 19 % higher total soluble solids (TSS) than Punjab Sona Cherry and 10 % higher than Punjab Red Cherry and also showed titrable acidity 20 and 9 % higher than the cultivar Punjab Red Cherry and Punjab Sona Cherry, respectively. The TSS and titratable acidity in tomato fruits increased with Mg application rates. A significantly higher yield was recorded with Punjab Sona Cherry (6.96 kg/m2) as compared to Punjab Red Cherry (5.63 kg/m2) and followed by Punjab Kesar Cherry (5.29 kg/m2) with the foliar application of 0.4 % magnesium sulphate.

However, the importance of magnesium (Mg) as an essential plant nutrient is well established, but its application has not been studied extensively specially in cherry tomato. The experiment was carried out during two successive seasons of 2018 and 2019 in polyhouse under ventilated condition to evaluate the effect of different Mg levels on growth, yield and fruit quality of cherry tomato grown under drip irrigation system. Foliar application of magnesium sulphate was done at three levels (0.2, 0.3 and 0.4 %) on three cultivars viz., Punjab Red Cherry, Punjab Kesar Cherry and Punjab Sona Cherry during vegetative stage at different time interval (at the first fortnight of January, February and March). The vegetative growth, yield and important quality traits of different cherry tomato cultivars, including TSS, titratable acidity were determined. Punjab Kesar Cherry cultivar showed 19 % higher total soluble solids (TSS) than Punjab Sona Cherry and 10 % higher than Punjab Red Cherry and also showed titrable acidity 20 and 9 % higher than the cultivar Punjab Red Cherry and Punjab Sona Cherry, respectively. The TSS and titratable acidity in tomato fruits increased with Mg application rates. A significantly higher yield was recorded with Punjab Sona Cherry (6.96 kg/m2) as compared to Punjab Red Cherry (5.63 kg/m2) and followed by Punjab Kesar Cherry (5.29 kg/m2) with the foliar application of 0.4 % magnesium sulphate.","PeriodicalId":39205,"journal":{"name":"Journal of Applied Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43867505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
