There is currently a demand to grow more crops in less area as a result of urbanization’s reduction of agricultural land. As a result, soil fertility is gradually declining. To maintain soil fertility, various management methods are used in modern times. The conventional tillage method is a traditional tillage method that damages soil structure, but zero tillage can improve soil quality. By maintaining soil structure with no-tillage, biological processes are frequently improved and microbial biodiversity is increased. This review helps to understand the role of tillage as well as cropping systems in increasing crop production by maintaining soil fertility. For agricultural production and environmental protection to be sustained for future generations, soil quality must be maintained and improved in continuous cropping systems. The nodulation, nitrogen fixation, and microbial community are all impacted by different cropping systems and tillage methods. They also alter soil properties including structure, aeration, and water utilization. The impact of tillage and cropping system practices such as zero and conventional tillage systems, crop rotation, intercropping, cover cropping, cultivator combinations, and prairie strip techniques on soil fertility is carefully summarized in this review. The result highlights that conservational tillage is much better than conventional tillage for soil quality and different aspects of different tillage and their interaction. On the other hand, intercropping, crop rotation, cover cropping, etc., increase the crop yield more than monocropping. Different types of cropping systems are highlighted along with their advantages and disadvantages. Using zero tillage can increase crop production as well as maintain soil fertility which is highlighted in this review. In terms of cropping systems and tillage management, our main goal is to improve crop yield while minimizing harm to the soil’s health.

Food security and maximum land use system are the priorities of crop production technique in the present global food growing environment. The tomato-Albizia lebbck agroforestry is an effective smart production approach. The aim of this research is to find out the appropriate combination of organic mulch leads the tomato Albizia lebbck agroforestry production as compared to sole cropping technique for growth, yield, and quality that brings health hygiene for fresh and cooked consumption. The experiment was laid out following two factors split plot design with three (3) replications. Tomato in open field (T0) and tomato under Albizia lebbeck woodlot agroforestry system (T1) were arranged in main plots. Conversely, the usage of organic mulches was set in sub-plots viz. M0= No mulch, M1= Ash mulch, M2= Saw dust mulch, and M3= Water hyacinth mulch. The results indicated the highest yield (32.65 t/ha) was found in water hyacinth mulch (M3) and the lowest yield (21.37 t/ha) was detected in M0 without mulch (control). The treatment M3 (water hyacinth mulch) gave the maximum sugar-acid ratio (12.04%) and minimum sugar-acid ratio (9.42%) was found in control (no mulch). Furthermore, the result showed the production potentiality was the highest yield (29.41 t ha-1) was found in tomato- Albizia lebbeck agroforestry (T1) and the lowest yield (25.95 t ha-1) was recorded in sole cropping of tomato (T0). The maximum sugar-acid ratio (11.37%) was found in tomato- Albizia lebbeck agroforestry (T1) and the minimum sugar-acid ratio (10.31%) was found in sole cropping of tomato (T0). On the other, the combined effect tomato- Albizia lebbeck agroforestry with water hyacinth mulch gave the highest yield (35.01 while, the lowest yield (22.47 t ha-1) was observed in sole cropping of tomato without mulch. The research finding also revealed the maximum benefit-cost ratio (4.94) was found from the tomato- Albizia lebbeck agroforestry which was 20 % higher than tomato was grown in sole cropping. Finally, the tomato- Albizia lebbeck agroforestry production in association with organic hyacinth mulch can be an effective production approach for maximum return in terms of yield, quality and money.

For ensuring the food security and maximum use of land, the potato production under a mango-based agroforestry system is an effective production approach. The purpose of this study was to assess the yield potential and the economic benefits of potato production under a mango-based agroforestry system. The potato tubers were planted in a 10-year-old mango orchard and open field condition. The experiment was laid out following a split plot design with three (3) replications. Potato production system under mango orchard and open field were arranged in main plots T0 = potato sole cropping (control) and T1 = potato under mango-based agroforestry system. On the other hand, potato intra-row plant spacing were in sub-plots S0 = 60 × 20 cm2, S1 = 60 × 25 cm2 and S2 = 60 × 30 cm2. The data of yield characters of potatoes were investigated. The cost of production, gross & net return and benefit-cost ratio was calculated for economic analysis. The results show that the closest (60 x 20 cm2) intra-row plant spacing produced the highest yield while the economic returns from potatoes grown under the mango-based agroforestry system were higher than those derived from cropped grown as a sole crop or potatoes cultivation alone (gross returns US$3508/ha, net returns US$1642/ha). Further, the benefit-cost ratio from the combined cultivation of potatoes and mangos was 2.14, which was 20 % higher than growing potatoes as a sole crop. Thus, the cultivation of potatoes under a mango-based agroforestry system offers a significant financial benefit to farmers while ensuring the sustainable use of vacant space in mango orchards
