AMA, Agricultural Mechanization in Asia, Africa and Latin America (ISSN: 00845841) is a peer-reviewed journal. The journal covers Agricultural and Biological Sciences and all sort of engineering topic. the journal's scopes are in the following fields but not limited to:
This study aimed at assessing the level of livelihood diversification and its determinants in the Uttarakhand hills using the Simpson diversification index and a multiple linear regression model from the data obtained from 200 sample farmers chosen through a multistage random sampling technique. The results indicated that there was 100 per cent engagement of households in agricultural activities, yet the proportion of average income derived from them was only 4.78 per cent. The value of the diversification index indicated that about 19 per cent of the sample households belonged to low, 49.50 per cent to moderate, and 31.50 per cent of households belonged to a high level of livelihood diversification. Further, the results of the multivariate regression equation indicated that household structure, dependency ratio, education of household, organisation membership, and training had positive effects, while age of household head and farm size showed negative effects on livelihood diversification. As the soil and topography in the state are not suitable for mono-cropping, mixed agricultural practises need to be adopted. Small scale industries, cottage industries, and tourism should be developed and have diverse skill development training programmes.
Germination increases the bioavailability of nutrients and sprouts are a good source of vitamins and minerals. Seeds of three mung bean varieties (SGC-16, SGC-20 and IPM-02-3) of Assam were sprouted at 24, 48, 72 and 96 h under dark at 25±2°C. Significant increase in moisture content, crude protein, crude fibre and ash contents, while crude fat, starch and carbohydrate content significantly decreased during the sprouting period. Mineral contents (Na, K, P, Ca, Mg, Fe, Zn, and Cu), vitamin C, niacin significantly increased during the sprouting period. Thiamine increased up to 72 h and riboflavin increased up to 48 h and then both showed decreasing trend. Antinutritional factors like phytic acid and tannin significantly decreased while, in vitro protein digestibility significantly increased during sprouting periods. The varieties SGC-20 and SGC-16 are nutritionally superior over the variety IPM-02-3 which can be recommended for use in breeding as sprout varieties.
Cytological studies of 50 introgressed trispecies derivatives of cotton genotypes obtained in BC1F21 generation of trispecies crosses of [(G. hirsutum x G. barbadanse) x G. arboreum] were carried out to determine the chromosome behavior, yield, morphology and fiber quality traits. Of these 12 introgressed trispecies derivatives were observed most diverse for these traits. During meiosis variation in chromosome number ranging from 47 to 54.5 was observed against the normal chromosomal behavior of G. arboreum (2n == 26) and G. hirsutum (2n=4x=52). Chromosome pairing revealed the presence of univalent, bivalent, trivalent and tetravalent compounds. Yield and morphologically these derivatives increased significantly over the check varieties while fiber quality traits viz., upper half mean length (UHML) and uniformity index were found to be inferior than the check hybrid DCH-32; however, it was found at par with other checks viz., NH-615, DHY-286 and PA-183. The fiber strength was found to be superior over all the checks. These results indicate that these developed lines had introgressed of character from species viz., hirsutum, arboreum and barbadense.
To observe the effect of rice husk biochar in inhibiting the carpogenic germination of Sclerotinia sclerotiorum, and its role in inducing defence mechanism in tomato plants against the pathogen to minimise the losses caused by Sclerotinia stem rot in tomato. In vitro and glass house experiment were carried out to test the effect of rice husk biochar in combination with bioagents against Sclerotinia sclertiorum. Rice husk biochar at the rate of 1%, 3% and 5% concentration completely inhibited the carpogenic germination of sclerotia. Rice husk biochar @1%+ Trichoderma harzianum @ 10gm Kg-1soil was found to be most effective amongst all the treatments in promoting plant growth and enhancing the production of defence inducing enzymes Phenyl ammonia lyase (PAL), Polyphenol oxidase (PPO), Peroxidase(PO) and Total Phenol Content (TPC) thus consequently reducing the disease severity.
Information about the soil physical and structural quality of diverse land-uses (LUS) is essential for the sustainable development, utilization, and protection of natural resource viz. soil in plateau of Meghalaya. In this study, depth wise (0-0.15 m and 0.16-0.30 m) particle size distribution, bulk density (BD), particle density (PD), maximum water holding capacity (MWHC), aggregated (Silt+Clay), structural stability index (St), mean weight diameter (MWD) and geometric mean weight diameter (GMD) were analyzed under Jhum-System, Mixed-Forest, Pine-Forest, Rice-Potato, Rice-Cole Crop, Upland Rice-Monocrop, Lowland Rice-Monocrop, Upland Pineapple-System and Upland Broom-System suited in Upper Shillong, East Khasi Hills, Meghalaya. The results showed alteration in sand, silt, clay, BD, PD, MWHC, AG (Silt+Clay), St, MWD and GMD in relation to diverse land uses (LUS). The Mixed-Forest soils had the lowest BD (1.15 Mg/m3), at surface and highest in Rice-Potato (1.39 Mg/m3). The mean content of PD and MWHC in all types LUS were varies between 2.40-2.75 (Mg/m3) and 45.04-58.37%, respectively whereas highest PD and MWHC was recorded in Jhum-System and upland Broom-System, respectively. The BD of different LUS was increases with depth and MWHC decreases with depth. The ranges of AG (Silt+Clay), MWD, GMD and St were ranging from 67.19-75.98%, 1.08-2.42 (mm), 0.61-1.25 (mm) and 3.81-6.87%, while highest and lowest value were observed in all LUS in surface soil Mixed-Forest and Rice-Cole Crop. On an average in the subsurface soil all soil aggregate parameters were decline in different LUS. Correlation between aggregating elements and aggregate stability parameters with MWD viz. GMD and St were positively correlated with MWD @ 0.01 per cent level (2-tailed) under different LUS in 0-15 cm whereas sand and clay have no correlation with MWD. Relationship between silt, AG (Silt+Clay) with sand had strongly negative correlation, while with St has strongly positive correlation @ 99 per cent confidence level.
