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)

Influence of Crop Geometry, Fruit Thinning and Nutrient Management on Yield and Yield -related Attributes of Watermelon (Citrullus lanatus Thumb.)

The present experiment was carried out during 2020-21 and 2021-22 in Jorhat, Assam with the objective to optimize the planting density for maximum yield and yield related attributes. The experiment was laid out in factorial randomized block Design with 3 factors viz. spacing, fruit thinning and INM (Integrated nutrient management) with three replications and the data of individual years were subjected to pooled analysis. The spacing levels were D1 (2.5m x 2m), D2 (1.5m x 1m) and D3 (1mx 1m) where F1 (no thinning), F2 (Thinning up-to 1 fruits /primary vine) and F3 (Thinning up-to2 fruits/primary vine) were the fruit thinning levels. A total of 4 INM treatments were given i.e. N1 (100% RDF), N2 (50% RDF + 50% RDN through FYM), N3 (50% RDF + 50% RDN through vermicompost) and N4 (50% RDF + 25% RDN through vermicompost + 25% RDN through FYM). The treatments significantly influenced the various parameters except a few. The experiment's findings showed that thinning the fruit and increasing the spacing between them had a favorable effect on the watermelon's growth and yield-related characteristics. Additionally, integrated nutrient management and fruit thinning at level F2 enhanced the watermelon's growth, yield, and quality metrics. Among the levels, N3 (50% RDF + 50% RDN through vemicompost was found to be the best
