The Green Revolution refers to a series of research, development, and technology transfer initiatives, occurring between 1943 and the late 1970s in Mexico, which increased industrialized agriculture production in many developing nations. The initiatives involved the development of high-yielding cereal grains, expansion of irrigation infrastructure, and distribution of hybridized seeds, synthetic fertilizers, and pesticides to farmers. The term "Green Revolution" was first used in 1968 by former USAID director William Gaud. The goal of the Green revolution was to increase the efficiency of agricultural processes so that the productivity of the crops was increased and could help developing countries to face their growing population's needs.

The global demand for good quality food is going to be increased gradually. Mushrooms are broadly used as healthy nutritious meals. The nutritional values of extracts from four distinct Pleurotus species—Pleurotus ostreatus, Pleurotus sajor-caju, Pleurotus sapidus, and Pleurotus columbinus—were determined in the current study. Firstly, proximate analysis of selected Pleurotus species was performed followed by the Bradford assay to analyze the protein spectrophotometrically; high-performance liquid chromatography (HPLC) was performed for sugar determination while GC-MS was done to determine fatty acids on organic extracts of selected mushrooms. Descriptive statistics were used to calculate the percentages while significance was determined by SPSS statistics. The results depicted that fat, protein, ash, fiber, energy contents, and total carbohydrate were in the range of 0.64-2.02%, 16.07-25.15%, 2.1-9.14%, 6.21-54.12%, 342.20-394.30 kcal/100 g, and 65.66-82.47%, respectively. The protein’s maximum concentration was observed in P. ostreatus followed by P. columbinus>P. sajor-caju>P. sapidus, sequentially. Various sugars may or may not be present in selected Pleurotus spps. Among the fatty acids, the prevalence of UFA was more than that of saturated fatty acids among all selected mushrooms. From this study, it is concluded that all four Pleurotus spps. have excellent nutritional composition and can be used as valuable food and a great source of biochemical compounds.

Increasing public concern in relation to health and environmental issues of organic waste leads to many solutions of waste management. Many different methods are discovered for proper waste management and disposal. Organic fractions of solid waste are treated with aerobic composting. It is one of the better treatments for organic waste. The important issue of concern here is the production of compost leachate with organic waste. In this study, to evaluate the competency of produced leachate as fertilizer and making the composting process more cost effective and environmentally friendly, liquid fertilizer prepared by Lahore Compost Company was used. Different percentages of leachate (0.2, 0.5, 1.5, 3.5, 5.5, 10.5, 15.5, and 25.5%) were prepared and germination rate of wheat was checked by evaluating its fertilizing quality compared to fertilizer. Results showed high germination and growth rate at lower concentration of leachate as compared with control and commercial fertilizer due to the presence of many suitable nutrients. This study was designed to compare the crop production efficiency of compost leachate with commercial fertilizer. It was revealed in this study that low leachate percentage give better crop production in case of wheat.
