Response of Sowing Dates, Crop Establishment Methods and Mulching on Growth, Productivity and Profitability of Spring Wheat at Rampur, Chitwan, Nepal

Intensive tillage with no crop residue after rice harvest in conventional wheat cultivation increases the turn around time, delays sowing and affects yield. A field experiment was carried out to assess effect of dates, establishment methods mulching their interaction on growth, productivity profitability spring at agronomy farm AFU, Rampur Chitwan, Nepal from November 2020 April 2021. The laid strip-split plot design, three dates (20th November, 5th December 20th December) vertical plots, two (Zero Conventional tillage) horizontal plots levels (0 t ha-1 5 straw mulch) sub-plots replicated thrice Vijay as test variety. Data regarding phenology, growth parameters, yield attributes were recorded, analyzed presented. research results revealed that date significantly influenced attributes, interactions. higher grain obtained well mulch (4511.49 & 4492.12 kg respectively). These yields statistically par zero (4363.74 4129.97 Net return B:C ratio than without mulch. Int. J. Appl. Sci. Biotechnol. Vol 10(4): 237-244.
