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:
Finger millet is highly self-pollinated crop in which emasculation is extremely difficult due to very small size of flowers. The presence of the male sterility will make crossing easier in finger millet which helps in generation of variability and exploitation of heterosis. Therefore, an investigation was aimed to identify male sterile line(s) in M3-M4 generation of, two gamma rays irradiated varieties of finger millet, GPU 28 and KMR 204. Plants with reduced pollen fertility were observed in both the mutated populations and progeny of these selected partial sterile mutants showed unusual segregation behaviour. Progeny of mutants with above 90% pollen sterility were crossed with pigmented varieties to check female sterility also. Few mutants showed good results on pollen sterility, seed set percentage in selfed as well as crossed ear. Identified partial male sterile mutants need to be evaluated in next generations for higher percentage of sterility and their stability.
Women's participation in farmer demonstrations is clearly important for achieving Sustainable Development Goal 5, which is gender equality. Agriculture decisions for conservation and sustenance are influenced by equality and equity. Gender has received minimal attention from researchers looking at farmer protests in India. As a result, the current research focused on the following questions: 1) What role do women play in Punjab's agriculture? 2) What role do women play in farmer protest if present? 3) What were the implications of farmer’s protests on women? The theoretical difficulties raised here have far-reaching implications, far beyond the Punjab region context. The findings indicated that women in large numbers participated in farmer’s protests in the states which are known for khap panchayats that led to the new role and empowerment. They were present with second in lead despite male-dominated society thereby challenging patriarchy. Along with household chores, they were continuously giving logistic support without which success of the protest was impossible. The farm laws had major implications on women who had limited bargaining power and preferred to sell their produce to nearby markets due to fewer transport facilities. Women’s struggles in the last year during the farmer’s protest portrayed that they are no more the silent backbone of agriculture and voicing out opinions that helped in achieving gender class unity and solidarity.
The pace at which new clothes are produced and discarded is an unhealthy process and not safe for the planet. Clothes dumped to landfills take decades to degrade and decompose while they are continuously emitting methane and pollute the soil and water. Moreover, the production process of cotton fibre has a high impact on the environment since it requires a great amount of water and chemicals. In order to keep up with the increasing consumption of textiles, upcycling of textile waste is considered as one of the way required to cope up effectively with the prevalent problem. Hence, a study was conducted to explore the possibility of upcycling apparel waste. The innovative upcycled utility articles were developed from pre and post textile and apparel waste. The cost acceptability of upcycled articles was assessed and the cost of the developed upcycled utility articles constructed by using entirely post apparel waste and combination of pre & post apparel waste was considered ‘appropriate’ as compared to upcycled utility articles prepared by using post apparel waste along with new fabric. Experts had high opinion regarding upcycling of pre and post apparel waste.
In view of the problems of large amount of fertilizer application, uneven application and inaccurate positioning of sweet potato fertilization machines at present in China, considering the distribution law of sweet potato roots and the characteristics of sweet potato planting patterns, a ridge-core arc-shaped uniform positioning fertilization technology was proposed in this paper. The arc shaper and spiral groove wheel fertilizer discharger are designed, the influencing factors that affect the uniformity of fertilization are analyzed, and the optimal working parameter range of the fertilizer discharger is determined. Furtherly, the rotation speed of the fertilizer discharge shaft, the spiral angle and the depth of groove are recognized as the test factors, the fertilizer discharge amount and the uniformity coefficient of variation of the fertilizer discharge are used as the indicators to carry out the quadratic regression rotation combination test. At the same time, the discrete element method is employed to simulate the process under different parameter combination settings, and the optimal parameter combination is obtained when the lift angle of the sheave is 79°, the groove depth is 3.7mm, and the speed of the fertilizer discharge shaft is 46r/min. Under the premise of the amount of fertilizer, the coefficient of variation of fertilizer discharge is smallest. By comparing with the actual operation effect, the simulation results are basically consistent with the field test conditions, which verifies the validity of the simulation test and the establishment of the regression model. This research can realize the uniform application of fertilizer in the ridge core at a certain depth and quantity, which can effectively reduce the amount of fertilizer application, improve the yield and the uniformity of sweet potato. At the same time, it provides a reference for the research and design of the sweet potato ridge core arc fertilization equipment.
The present investigation on “Effect of different storage containers on incidence of stored insect pests” was carried out by conducting a laboratory experiment by using various packaging materials viz. earthen pots, bags metal bins, glass bottles, plastic containers, porous HDPE bags, cloth bags, polythene bags of 700 gauge and gunny bags at Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur during 2019-20 and 2020-21. The results of the present study indicate that the polythene bags of 700 gauge treatment was recorded the significantly minimum mean per cent seed damage, weight loss and moisture content with 7.67 and 8.13; 15.61 and 16.33; and 13.43 and 13.52, respectively and the maximum mean per cent seed damage and moisture content with 30.27 and 29.53; 41.61 and 40.97; and 14.75 and 14.88, respectively in case of Sitotroga cerealella (O.) on maize and same results were also recorded Callosobruchus chinensis (L.) on blackgram and Rhyzopertha dominicia (F.) on wheat during the 2019-20 and 2020-21. Considering all the containers, the trend in the protection of stored cereals and pulses grains from insect population showed the following decreasing order, polythene bags of 700 gauge>plastic container>glass bottles>bags metal bins>porous HDPE bags>Cloth bags>gunny bag>earthen pod.
