Traditionally, common salt (NaCl) is applied to control broadleaved weeds under shifting cultivation in Nagaland. The aim of the present study was to find out whether such practice is harmful to the soil. For this, an experiment was conducted on upland rice with 12 treatments, viz. control, weedy check and different doses of NaCl from 20 to 200 kg ha-1. Soil samples were collected at several phases of shifting cultivation and analysed for organic carbon, available N, P, K, pH, electrical conductivity (EC), cation exchange capacity, exchangeable sodium percentage and sodium adsorption ratio. Yield and yield attributing characters were measured and economics was computed. The results revealed that soil organic carbon (SOC) increased after harvest, but decreased after one year. In contrast, available N, P and K decreased during the crop growth and post harvest period. Weedy check followed by an application of 100 kg NaCl ha-1 realized the highest gross and net returns. It was observed that NaCl did not exert an undesirable influence on pH, SOC and available NPK; however, EC increased for a short time. The results were confirmed by the verification trial. The yield of rice was highest in 100 kg NaCl ha-1 treatment among the treated plots. Hence, this may be recommended to control weeds under shifting cultivation.Keywords

A study on varietal evaluation in taro for growth, yield and quality attributes was carried out in a replicated experiment and morphological and chemical analysis was done. Significant differences were recorded for all the characteristics studied. 'Panchmukhi' recorded highest plant height (179.33cm), petiole length (153.11cm), petiole breadth (13.87mm) and leaf size (3095.67cm2), LAI (1.14), corm length (152.41mm) and breadth (107.77mm), average corm weight (1500.00g) and corm yield (20.00t/ha). 'C-3' recorded maximum (15.00) petiole number and cormel length (85.93mm). Cormel yield (15.29t/ha), total yield (25.92t/ha) and number of cormels per plant (30.33) was found to be maximum in cv. White Gouriya. 'ML-2' recorded maximum (7.33) number of side shoots. Highest average cormel weight (72.85g) was maximum in cv. Arcol-7, and 'Arcol-5' recorded maximum (67.43mm) cormel breadth; the least blight incidence percentage (8.00) was recorded in 'Nayabungalow'. As for biochemical constituents, 'Nainital' recorded the highest (5.85%) total sugars, 'Kandha-5' exhibited the highest (34.67%) starch content and 'Nadia Local' with showed highest levels of oxalic acid (1.05mg/100g). Highest dry matter content (27.50%) was recorded in cvs. KCA-1 and Panchmukhi, while the highest moisture percentage (82.83) was recorded in 'IG Coll-5'.Keywords

Ginger (Zingiber officinale Rosc.) is one of the widely grown commercially important spices of North East India. Storage of fresh ginger for more than one month is problematic due to severe weight loss and sprouting. The present study was conducted to preserve the peeled ginger slices in acidified brine solution in plastic containers at ambient condition. The ginger rhizomes of Bhola variety harvested at 270 days after planting was found better for preservation of ginger slices of 1.5-2.0 mm thickness in brine. The ginger slices treated with 9 per cent brined solution acidified with 2 per cent citric acid and potassium metabisulphite and benzoic acid 50 ppm each as preservative resulted in better retention of biochemical qualities like crude protein (5.67%), total soluble carbohydrate (12.89%), oleoresin (4.17%) with better organoleptic qualities and no microbial growth after 180 days of storage. The ginger slices could be safely stored up to 180 days. The brined ginger slices may serve as substitute for fresh ginger during the lean period.

Ginger (Zingiber officinale Rosc.) is one of the important high value crop, cultivated widely in the North Eastern Region of India. Of the total ginger production, around 93.4 per cent becomes a marketable surplus. This huge amount of marketable surplus is sold by the farmers at a very low price. The ginger producers of the region have not been benefited to the desired extent due to absence of proper processing units and storage facility locally. The traditional ginger drying methods used by the farmers are varied, haphazard and risky, resulting in mould growth and destruction of some heat sensitive pungent properties. Considering the huge production, potentiality, market demand and its agro-climatic suitability in the region, an experiment on post harvest treatments on shelf-life and quality of dehydrated ginger var. 'Bhola' was conducted in the Quality Control and PHT Laboratory of Department of Horticulture, Assam Agricultural University, Jorhat. The freshly harvested ginger rhizomes were washed, peeled and cut into small shreds. The ginger shreds were pretreated with different combinations of salt solutions viz., 4 per cent,6 per cent, 8 per cent and 10 per cent, citric acid viz., 1 per cent, 2 per cent, 3 per cent and 4 per cent and ascorbic acid 2 per cent in general. The treated samples were dried in oven for 7 hours at 60oC and stored in plastic containers at ambient conditions. The dehydrated ginger shreds treated with 10 per cent salt solution + 4 per cent citric acid + 2 per cent ascorbic acid recorded the highest crude protein (5.73%), oleoresin (4.31%), total soluble carbohydrate (12.89%) and overall sensory score (7.93%) without microbial growth till 180 days of storage. The dehydrated ginger shreds could be safely stored upto 180 days.Keywords

In this study, 110 taro landraces were characterized using 19 quantitative traits. Statistical tools like descriptive statistics, Shannon–Wiener diversity index, principal component analysis (PCA) and cluster analysis were used to evaluate diversity. Descriptive statistics showed significant variation among the landraces for the 19 quantitative traits studied. The highest coefficient of variation was found in the yield, number of suckers, leaf width and total oxalate. The corm length (H′ – 1.06) and starch content (H′ – 1.20) had the highest Shannon–Wiener diversity index. PCA resulted in seven principal components (PCs), which explain 70.65% of the total variation. PC1 was mainly associated with plant height, leaf length, leaf width, petiole length and plant spread. PC2 was associated with yield, moisture content, corm length and total oxalate. PC3 was associated with dry matter content and disease index. The cluster analysis using the weighted neighbor-joining method resulted in five major clusters based on geographical location. Cluster IV had a maximum of 54 landraces, and cluster III had a minimum of five landraces. The present study, which identified high genetic diversity and plant height, number of suckers, leaf length, leaf width, corm length, yield, total oxalate content and disease index, can be useful in taro varietal improvement programmes.Keywords
