Effect of straw and plastic mulches on growth and yield of zero tillage potato (Solanum tuberosum L.) in the Coastal Khulna Region of Bangladesh
23-30.Views:64A randomized complete block design experiment was undertaken at the field laboratory of the Agrotechnology Discipline, Khulna University, Khulna, from November 2021 to March 2022 to ascertain the impact of various mulch treatments on zero tillage potato cultivation. The experiment employed BARI Alu 78 as the planting material and utilized three replications with five distinct mulch treatments. These mulch treatments were identified as follows: Straw mulch (T1), Mulch film (T2), Black polythene (T3), White polythene (T4), and Blue polythene (T5). The metrics that were recorded included the number of sprouts, plant height, number of leaves per plant, leaf width, leaf length, number of tubers, tuber length, tuber breadth, number of defective tubers, weight of defective tubers, and tuber weight. Different mulching techniques significantly influenced the overall crop yield and the underlying factors that influenced the results. The mulch film treatment resulted in the highest yield, with a production of 34.76 tons per hectare, followed by black polythene (28.11 tons per hectare), straw mulch (23.74 tons per hectare), white polythene (20.44 tons per hectare), and blue polythene (18.66 tons per hectare). The economic analysis revealed that mulch film had a high benefit cost ratio along with high input and output. Black polythene came in second place when the benefit cost ratio was compared to that of mulch film and the rest of the three treatments. Combining zero tillage with mulch film or black polythene demonstrates significant potential for becoming a cost-effective practice in the coastal region of Bangladesh.

Growth and yield performance of garlic varieties under zero-tillage and tillage system
46-54.Views:393Bangladesh Agricultural University (BAU) developed four garlic variety viz., BAU Garlic-1; BAU Garlic-2; BAU Garlic-3; and BAU Garlic-4 were tested under two cultivation systems viz., zero-tillage and tillage to find out a suitable variety for zero-tillage system. This study was conducted following randomized complete block design with three replicates. Results showed that planting system had significant influenced on growth, yield contributing traits and bulb yield of garlic. It was also observed that all the studied traits were higher in zero-tillage condition as compared to tillage system. There were significant variations noticed among the garlic varieties on plant growth and yield traits. However, in combination of planting system and variety, it was found that BAU Garlic-3 performed superior on plant growth and bulb yield of garlic under zero-tillage system. From the findings of this study, it can be concluded that BAU Garlic-3 could be useful technology for cultivation of garlic in zero-tillage system.
