Effects of Organic Manure Source and Weeding Frequencies on Growth Parameters of Jute Mallow...

Field trials were conducted at the Federal College of Forestry and Mechanization Afaka Kaduna, situated between latitude 10° 35”N and longitude 007° 21”E at an altitude of 644 m above sea level, during the 2018 and 2019 dry seasons to determine the effects of organic manure source and weeding rates on jute mallow growth parameters (Corchorus olitorious). There are ten different variations of poultry manure + weed free, cow dung + weed free, goat dropping + weed free, poultry manure + weeding at 2 WAT, cow dung + weeding at 2 WAT, goat dropping + weeding at 2 WAT, poultry manure + weeding at 4 WAT, and poultry manure + weeding at 2 WAT in the experimental treatments. Cow dung + weeding at 4 WAT, goat dropping + weeding at 4 WAT, and no organic manure application + no weeding were all repeated three times using a randomise full block template (RCBD). Crop vigour score, plant height, shoot diameter, number of leaves, and number of primary branches were among the growth parameters observed and calculated. The study's findings revealed that at harvest (8 WAT), all of the treatments had a substantial impact on the vigour of the jute mallow crop, with the lowest score being observed with no nutrient + no weeding as the monitor. Plant growth at harvest was substantially taller with the application of poultry manure + weeding at 2 WAT, according to the results. Finally, because of the lower weed infestation, poultry manure at 4 tons/ha + weeding at 4 WAT resulted in taller plant height, wider shoot diameter, increased number of shoots, and number of branches than all other treatments. As a result, it is recommended as the best treatment combination for achieving the best jute mallow growth rate.
