Influence of Different Types of Organic Manure and Weeding Frequencies on Weed Parameters and....

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 impact of different forms of organic manure and weeding frequencies on weed parameters and leafy yield of jute mallow (Corchorus olitorious). Ten different combinations 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, cow dung + weeding at 4 WAT, goat dropping + weeding at 4 WAT, poultry manure + weeding at 4 WAT, cow dung +Dropping + weeding at 4 WAT, as well as no organic manure application + no weeding, were repeated three times in a randomise full block design (RCBD). Popular weeds infesting the plots, weed dry weight, weed control index, weed competition index, and cumulative leaf yield at 2, 4, 6 WAT and harvest were the weed parameters and yield components observed and calculated. The plots were heavily infested with three major weed species: Synedralla nodiflora Gaertn, Gomphrenacelosiodes, and Cyperus esculentus, according to the findings. The application of poultry manure + weeding at 2 WAT resulted in the highest weed completion index, while cow dung + weeding at 4 WAT and goat fall + weeding at 4 WAT resulted in the lowest weed competition index. The results also showed that plots with poultry manure + weedfree application had the highest mean cumulative yield value of 236kg per hectare, followed by plots with poultry manure + weeding at 4 WAS (223 kg)the plots with no organic manure + no weeding had the lowest mean cumulative yield value of 111 kg per hectare as compared to the control treatment. In comparison to other forms of organic manure and the control, the study found that poultry manure plus weed free produced the highest yield of jute mallow.Farmers in the study region should use poultry manure in combination with weedfree treatment to get a bumper crop of jute mallow (Corchorus olitorious).
