About Lesson
Sowing methods :
- Seed drilling by ZT -seed drill machine :
- Surface seeding :
- Broadcasting of wheat seed or surface of untilled soil.
- Done before harvest of rice / day or after harvest.
- Practiced under low land condition where the residual moisture of soil is too high or low and not suitable for tillage operation.
- Recommended dose of seed is 120-150 kg/ha.
- Seed is mixed with fresh cow dung @ 1% and spread on shady area to dry . Done to protect seed from direct exposure to sunlight and protect seed from picking by birds.
- Other crop management are similar to CT method.
Nutrient management/ Manure :
- Generally , organic manure like FYM or compost are applied late spring before cultivating rice.
- If possible , farmer can also apply 10 t/ha manure before land preparation in wheat crop too.
Fertilizer dose recommendation in Nepal :
- Generally , fertilizer is recommended on the basis of soil test.
- Under low land condition 100:50:30 kg NPK should be applied.
- Rainfed condition : 50:50:20 kg NPK/ha .
- Under zinc sulphate per hactare during land preparation.
- Under late sowing condition , fertilizer dose is reduced.
Time of application :
- Under rainfed condition , apply full dose of all source of nutrient at the time of final field preparation.
- Under irrigated condition , apply full dose of phosphorous , potassium and half dose of nitrogen at the time of final field preparation.
- Top dressing under sand and silt dominant soil remaining half dose of nitrogen is top dressed around 20-25 DAS (CRI stage ) at the time of first irrigation.
- Top dressing under sand and silt dominant soil remaining half dose of N is top dressed at two splits at CRI and jointing stage along with irrigation.
