Type: article
Abstract: The research was conducted in 2022 in the Agronomy Student's Experiment Farm at Sindh Agriculture University Tando Jam. It used a complete block design with randomization. The main goal was to evaluate how much adding different amounts of FYM and nitrogen-phosphorus affected the growth and seed production ability of sunflowers. The research had five different FYM options and nitrogen-phosphorus levels. The HO-1 variety was given these treatments. The assigned treatments were as follows: T1 = control (no FYM, 0 kg/ha nitrogen and 0 kg/ha phosphorus); T2 = adding a small amount of farmyard manure plus some extra nutrients in the form of nitrogen at a rate of 30kg per hectare, along with an additional quantity of 15 kg per hectare. The best results were seen in T5 (5 tons of farm FYM + fertilizers, with 120 kg per hectare of nitrogen and 50 kg per hectare of phosphorus). This method resulted in the most plants on a square meter (9.11), the tallest plant growth at about 248.8 cm high; T5 was closely followed with good results (a lot of FYM plus 120 kg per hectare nitrogen and 50 kg phosphorus). The research indicates that the optimal combination for enhancing sunflower growth and yield includes applying 120 kg ha-1 of nitrogen, 50 kg ha-1 of phosphorus, and incorporating 5 tons of FYM.
