Abstract

The experiment was conducted to assess the shelf life of unripe banana with ethylene absorbent stored in different packaging materials viz., HDPE, polyethylene and polypropylene (non-perforated) bags of different gauges. Significantly minimum weight loss, spoilage, TSS and Pulp/peel ratio recorded by fruits stored in 250 gauged non-perforated HDPE bags followed by 175 gauges non –perforated HDPE bags with ethylene absorbent at all the sampling dates. However, highest acidity was recorded at all the storage period due to the same packaging materials. The spoilage was recorded on 15 days of storage to the tune of 2.15% and 1.054%, respectively by fruits stored in 175-gauged HDPE bags and 250-gauged HDPE bags. The control fruits were spoiled on 9^th day.

Abstract

The experiment was conducted at Post Harvest Technology Scheme, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experiment deals with the storage of kagzi lime in perforated polyethylene and non-perforated polypropylene bags of 100, 200 and 300 gauges and with different treatments viz., chemicals and wax emulsion. The fruits stored in 200 gauged perforated polypropylene bags recorded minimum pH, TSS, brix/acid ratio and maximum content of acidity and ascorbic acid at the end of 70 days in cold storage condition. Among different chemicals and wax emulsion, waxol 6%+ captan 0.1% recorded minimum pH, TSS, brix/acid ratio and maximum content of acidity and ascorbic acid at the end of 30 days in case of CS and 20 days in cold storage. However, ,it revealed that, fruits packed in 200 gauged perforated polypropylene and polyethylene bags exhibited shelf life upto 70 by slowed down biochemical changes.

Abstract

The present study was undertaken to assess the effect of seed pelleting on growth, yield and morphological parameters in soybean during kharif 2000-01. Various materials like adhesive, filler and chemicals were used for seed pelleting. Mean plant height was significantly improved by seed pelleted with thiram + CMC + filler. Seed pelleted with DAP + CMC + filler, thiram + CMC + filler and CMC alone recorded 0.0965, 0.0332 and 0.03 g / dm2/ day of net assimilation rate (NAR) at 45-60, 75-90 DAS and at harvest stage respectively. There was a steady declines in leaf area ratio in all treatments up to harvest. All pelleting treatments recorded significantly higher leaf area ratio than control. Seeds pelleted with thiram + CMC + filler recorded seed yield of 28.76 q ha^-1 followed by borax + CMC + filler (27.58 q ha-1 seed yield). However, seeds pelleted with thiram + CMC + filler was found beneficial in recording highest pod per plant, number of seeds per pod, test weight (100 seed weight), harvest index, oil content and seed yield per plant. All pelleting treatment noted rapid increase in CGR (crop growth rate), RGR (relative growth rate) and LAI (leaf area index).
