Thousands of acre wheat crop is grown in Punjab through zero tillage technology. Weed issue is not considered as more severe in early sown crop. Spray of herbicide may be escaped in some cases. In case of late sowing, weed problem may be faced. Adoption of cares and safe control measures have been proposed in this video.
Zero tillage technology is of wheat planting after rice crop particularly in the rice zone of Punjab is getting more and more popularity among the farmers. Introduction of Kabuta Rice harvester has facilitated zero tillage more. Zero tillage has several edges over land perpetrated wheat cultivation in clayey or heavy soils of rice zone. Expenditures of soil preparation are saved and timely sowing is ensured. Zero tillage also has the advantage of efficient use of added fertilizers like dap fertilizer, diammonium phosphate, sop, sulphate of potash, potassium sulphate fertilizer, sulfate of potash fertilizer, urea fertilizer. Weed problem is also minimum in case of zero tillage. Sometimes, we do not need a herbicide for weeds.
NPK and micronutrients are variably used by wheat crop at its different growth stages. Wheat plants need energy and organic matter for root development. Phosphate fertilizers are added at the sowing time for this purpose. Initial requirement nitrogen of wheat seedlings is met with basal application diammonium phosphate in most cases. Plants need NP and K in a well-balanced manner for tillering. We add most shares of nitrogen and zinc at the time of 1st irrigation. Basal application of P and K suffices and serves wheat in a better way. For stem elongation at jointing stage, plants need more amount of nitrogen for amino acids development, calcium for stem stiffness and K for resistance and movement of photosynthates. Most our calcareous soils do not need supplementary calcium, nitrogen is replenished at 2nd irrigation in most cases and basal application of K suffices its potassium requirements. In addition to proper amount of N and P, Plants need maximum amount of boron and potassium at booting, earing, pollination and milky stages. That is why, additional application of boron and potash is recommended at these stages. Readily available mixed fertilizers like NPK (13:02:43 or o5:15:45 and many others) plus boron are advised for maximum yield of wheat crop.
Wheat is an important crop of Pakistan. There is a need to understand its behavior to fulfil its requirements at different stages. In this video, needs of different nutrients at different stages has been discussed.
Yield of wheat can be enhanced by using different elements at different stages. Following are some specific keywords which do not need to be paid attention. Just focus on video.
