<div style="text-align: justify;">The mango fruit Cv. Kesar were exposed to ethylene gas (100 ppm) for 12, 18 and 24h in fruit ripening chamber (29.4-31.9oC. with 65-84 % R.H.) and the untreated fruit was kept at ambient temperature (26-30oC with 54-62% R.H.). The fruits were then removed from the ripening chamber at the end of exposure period, packed in corrugated fibreboard boxes and then kept at ambient condition to study the ripening behaviour. In ethephon dip treatments, the mango fruits were treated with ethephon at the concentration of 500,750 and 1000 ppm for five minutes, drained, packed in corrugated fibreboard boxes and then kept at ambient condition. It was found that mango Cv. Kesar exposed to the ethylene gas in the ripening chamber and ethephon dip treatment triggered the ripening process. It was observed that mango fruits Cv. Kesar ripened by exposing them to 100 ppm ethylene gas in ripening chamber for 18 hrs and storage at ambient condition recorded the maximum shelf life of 6 days and showed better results in respect of high overall acceptability score of 8.77. Similarly, mango fruits Cv. Kesar ripened by ethephon dip treatment of 750 ppm for 5 minutes and storage at ambient condition recorded the maximum shelf life of 8 days and showed better results in respect of high overall acceptability score of 8.66, respectively. The cost of ripening chamber for 800 kg fruits on per day interest and ethylene gas was considered for calculating the cost of ripening. The cost was found to be Rs 0.69 per kg.&nbsp;</div>

Effect of ethylene on physiological changes during ripening of mango (<em>Mangifera indica</em> L.) Cv. Kesar

<div>In the recent years, increasing labour cost and shortage of labour being the major constraints to follow manual harvesting in cotton in staggered manner. Further, it is very expensive and farmers would like to increasingly opt for mechanical harvesting. In this context, it is suggested that research should focus to reduce cost of cultivation substantially by promoting the use of synchronized maturity in cotton and use of defoliants to encourage mechanical harvesting. In agriculture, defoliants are used to eliminate the leaves of a crop plant so that they do not interfere with the harvesting by machinery. Early harvesting with good boll opening can also be achieved by use of defoliants. The use of defoliants also reduces the trash content in picked cotton which will also help in improving the quality of cotton. There is a need to identify suitable defoliant with suitable dose and time of application so as to facilitate mechanical harvesting in rainfed cotton. Some of the successful defoliants for uniform boll bursting and higher yield of cotton such as rthrel, rthepon, mepiquat chloride (MC), sodium salt and DU (Dropp Ultra) are the hormonal defoliants and TDZ thidiazuron butifos, merphos, tribufos and tribufate are the herbicidal defoliants. The best combination of thidiazuron + diuron (DCMU), pyraflufen ethyl, thidiazuron + diuroncellular isozyme, Ethephon + AMADS, ethephon + cyclanilide&nbsp; ethephon + tribufos Mepiquat chloride (MC) + cyclanilide may be recommended to facilitate mechanical harvesting in cotton.</div>
