Abstract:
Pots experiment was carried out in july (2016) at the Demonstration Farm of the College of Agricultural Studies, Sudan University of Sciences and Technology, Shambat to study the effect of different types of fertilizers and their combination on growth and forage yield of guar (Cyamopsis tetragonoloba L). The treatments consisted of phosphorus, potassium, phosphorus with humic acid, potassium with humic acid and phosphorus with potassium and humic acid and control. The experimental design was randomized complete block. With five replications. Data on various guar growth and forage yield were collected and analyzed.
Results showed highly significant differences (p≤0.05) among the treatmentS for all the studied growth and yield parameters except stem thickness. The results also demonstrated that the combined effect of phosphorus, potassium and humic acid treatment recorded the highest guar growth (except the number of branches/ plant) and forage yield attributes. The highest number of branches/ plant was achieved by the control. While, phosphorus and humic acid produced the lowest guar forage fresh and dry yields
