There is a diverse variety of pumpkin types found in nature, and their potential as a source of pro-vitamin A can be evaluated with the goal of using them in traditional plant breeding or biofortification projects with the goal of increasing the beta-carotene content. The objective of the study was to determine the β-carotene contents in locally available varieties and their hybrids (L x T fashion) of fully ripened pumpkins to verify their use in further breeding program as parents. High Performance Liquid Chromatography were used to identify and quantify the β-carotene contents in. In this study carotene content in pumpkin fruit flesh varied from 4.70 µg per g (L2) to 24.57 µg per g (L4) in lines whereas in testers it ranged from 7.73 µg per g (T3) to 11.59 µg per g (T2). Among the 18 crosses of study, the lowest and highest values of β carotene content recorded by the crosses L4 x T1 (2.54 µg per g) and L3 x T2 (89.60 µg per g) respectively. In total, six hybrids exceeded the parents in their β carotene content above the mean value (20.57 µg per g). The highest carotene content recorded by L3 x T2 (89.60 µg per g) followed by L1 x T1 (40.32 µg per g) and L2 x T2 (28.06 µg per g).
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.
