Standardization of packaging technique(s) for the distant marketing of Rhynchostylis retusa

A postharvest experiment was conducted at the Department of Horticulture, AAU, Jorhat, to study the effect of different packaging technique(s) for the distant marketing of Foxtail orchid spikes. The seven treatments were as follows: T1: CFB box (control); T2: wrapping with 200 gauge polyethylene sheet + KMnO₄ sachet + CFB box; T3: wrapping with butter paper + KMnO₄ sachet + CFB box; T4: wrapping with Brown Paper + KMnO₄ sachet + CFB box; T₅: plastic vial containing 8-HQS (25 ppm) + wrapping with 200 gauge polyethylene sheet + CFB box; T6: plastic vial containing 8-HQS (25 ppm) + wrapping with butter paper + CFB box; and T7: plastic vial containing 8-HQS (25 ppm) + wrapping with Brown Paper + CFB box. Among these packaging treatments, T5 resulted in a significantly longer vase life (7.33 days after 3 days of storage under ambient conditions). Postharvest parameters such as the PLW (6.58%), TSS (10.08%), MSI (78.28%), and wilting of the first floret (3.41 days) were found to be greatest in T5. However, in terms of biochemical parameters, T5 was similar to T6 in terms of carbohydrate content (63.49 and 62.08 mg/100 ml, respectively), protein content (15.23 and 15.18%, respectively) and anthocyanin content (6.37 and 6.30 mg/L, respectively)

Termite mound soil based potting media: a better approach towards sustainable agriculture

Termite mound soils are known to possess unique physico-chemical and biochemical properties, making them highly fertile. Considering their rich nutrient content, the objective of the current experiment is to assess the physico-chemical properties and enzyme activities of termite mound based potting media and evaluate theirperformance for further exploration in floriculture. Potting media consisting of termite mound soil (TS) of a subterranean termite, Odontotermes obesus were prepared in 7 different combinations with garden soil (GS), sand (S) and farmyard manure (FYM) and a control (without termite mound soil), i.e., T1 (TS, GS, S, FYM (v:v:v:v /1:2:1:1)), T2 (TS, GS, S, FYM (v:v:v:v / 2:1:1:1)), T3 (TS, S, FYM (v:v:v / 2:1:1)), T4 (TS, GS, FYM (v:v:v / 2:1:1)), T5 (TS, GS, S (v:v:v / 2:1:1)), T6 (TS, S, FYM (v:v:v / 3:1:1)), T7 (TS, S, FYM (v:v:v / 1:1:2)) and control (GS, S, FYM (v:v:v / 2:1:1)). The samples were then analysed in laboratory. Experimental analysis on physico-chemical and biological parameters revealed superiority of T7 (TS, S, FYM (v:v:v / 1:1:2)) in terms of pH (7.15), organic carbon (2.13%), available nitrogen (526.02 kg ha−1), available phosphorus (56.60 kg ha−1), available potassium (708.19 kg ha−1), dehydrogenase activity (18.21 μg TTF g−1 soil day−1), Phosphomonoesterase (PME) activity (46.68 54 μg p-nitrophenol/gsoil/h) and urease activity (3.39 μg NH4-N g−1 soil h−1). Whereas T4 (TS, GS, FYM (v:v:v /2:1:1)) registered superiority in terms of PME activity (50.54 μg p-nitrophenol/gsoil/h), Fluorescein diacetate (FDA) activity (11.01 μgfluorescein/gsoil/h) and Soil Microbial Biomass Carbon (SMBC) (262.25 μg/g). Subsequent to the laboratory analysis, two best potting mixtures (T7 & T4) were selected and their performance was assessed by growing a test crop, Tagetes erecta cv. Inca Orange. Considering the growth parameters, the potting media: T7 was found to be significantly superior in terms of plant spread (39.64 cm), leaf area index (4.07), fresh weight (37.72 g), yield (317.81 g/plant), and diameter (9.38 cm) of flower over T4 & control. The Benefit:Cost (B:C) ratio meaning the ratio of net returns to total cost of cultivation was determined. The B:C ratio of raising marigold flower as potted plant in T7 was 1.10 whereas the B:C ratio of the potting mixture of T7 was 2.52. This shows that T7 potting media is also economically viable choice for commercial purposes

Not AvailableThe initiation of modern agriculture can be traced back to the subsistence production system that started in small plots around the household. The system have persistently endured the test of time and continued to play a vibrant role in providing food and income for the family. This production system is still in vogue in the developing as well as few developed countries in Asia, Africa and Latin America. Broadly, this production system around the dwelling houses is the ‘Home garden’, a land use system involving deliberate management of multipurpose trees and shrubs in intimate association with annual and perennial agricultural crops and invariably livestock within the compounds of individual houses, the whole tree crop-animal unit being intimately managed by family members (Fernandes and Nair, 1986). Similarly, Baree in Assam also means a traditional land-use practice, mostly around the dwelling house and sometimes in isolated distant locations, where numerous plant species including timbers, firewood, vegetables, fruits, plantation crops, spices, herbs, ornamentals along with some other components of farming systems, viz., livestock, poultry, fishery, sericulture, bee-keeping, etc. maintained by the members of the farm family with the primary objective to fulfill various household needs.Not Availabl
