- Package of Production Technology through sowing time, ridge and flat sowing, plant density through plant spacing, fertilizer and irrigation requirements.
- Cotton Seed Viability Test.
- Comparison of Tillage Test.
- Feasibility of inter-cropping, short season crops with cotton.
- To increase soil productivity through crop rotation.
- Collection of weeds and their control.
- Meteorological data and its impact on cotton crop.
For profitable returns, formulating the recommendations for optimum sowing time, plant spacing, irrigation and fertilizer doses and their time of application, removal of weeds, cultural practices etc. are important to work out.
Findings are summarized as under:
Sowing for lower Sindh should start from March to mid of April. In control part of Sindh, from mid-April to May. For upper part, from mid-May to mid-June.
Spacing from plant to plant, 9 inches and apart 2.5 feet, may be kept.
Optimum number of plants, 20,000 to 24,000 per acre. Fertilizer trial results suggested that one bag of DAP at sowing time, two bags of urea in three split doses i.e. ½ bag with 1st irrigation other ½ bag at second irrigation and remainder at peak following.
For better moister retention, good germination and health growth, soaking dose with 2 irrigations may be applied.
Cotton required 7 to 8 irrigations for obtaining high seed-cotton yields.
Herbicides Dual Gold 960 EC and Stomp 330 EC as pre-emergence provide good Control of Weeds.
1st pick is preferable for seed purpose to provide good seed germination
