Lessons learnt from past experiences push for an alternate way of crop production. One such is conservation agriculture (CA), which can be seen as a new way forward for conserving resources and enhancing productivity to achieve goals of sustainable agriculture. In recent past, progressive and significant efforts are made to develop, refine and disseminate conservation-based agricultural technologies across globe. Tremendous efforts on zero-till practices and surface management with crop residues for crop production were reviewed. This work was done at Department of Agronomy, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai-625 104, Tamil Nadu, India. A systematic cum integrative review of research work done in different parts of World, particularly in India was comprehended. Literature search was done during 2020. About 200 review and research papers were screened from various databases like TNAU e-library, ARCC journals, google scholar, research gate and scopus and 84 papers were used. This review article comprehensively documents major principles of CA along with extent and spread of CA across the globe. It also highlights CA in Indian perspective. Various merits and demerits were also discussed with literature support. This review paper discusses rising concerns of conventional agriculture systems with regard to its adoption, positives and negatives of conservation agriculture in promoting conservation agriculture in tropics.

Unlabelled: Back ground: Careful evaluation of patients and proper treatment with right techniques are essential for successful outcome of assisted reproduction. To obtain satisfactory results, it is necessary to assess ovarian reserve before planning treatment., Objective: To evaluate anti-mullerian hormone as a predictor of fertility potential in terms of ovarian reserve and ovarian response reflected by antral follicles and mature oocyte counts in response to menotrophin stimulation in in vitro fertilization (IVF) women from Gaza Strip., Materials and Methods: This prospective cohort study consisted of 81 women (mean age 28.7 years) attending IVF at Al-Basma Fertility Center in Gaza City. Blood withdrawal for antimullerian hormone measurement was performed in all the patients and the number of oocytes and embryos were recorded., Results: The total number of retrieved oocytes was inversely associated with age (12.5±4.5, 11.0±5.4 and 6.9±4.7 at age ≤25, 26-35 and >35 years, respectively (F=4.793 and p=0.011). The ovarian response to Menotrophin (FSH 75IU, LH 75 IU) stimulation was better for younger age. There was a significant positive association between ovarian response in terms of total number of oocytes and antimullerian hormone levels. The maximum level of antimullerian hormone was observed in females who achieved positive pregnancies (4.5±2.5 ng/mL) followed by negative pregnancies (2.9±1.8 ng/mL) with significant differences (F=6.862 and p=0.002). Correlation coefficient revealed that the number of mature oocytes showed strong positive correlation with the antimullerian hormone levels (r=0.469, p=0.001)., Conclusion: Anti-mullerian hormone can be used in IVF programs as a good predictor of ovarian reserve and ovarian response.
