Effect of Different Organo – Chemical Amendment on Performance Chickpea (Cicer Arietenum), Soil Characteristics and Enzyme Activities

In To evaluate the effect of organo – chemical amendments on the growth and yield of Chickpea and physico – chemical characteristics and enzyme activities of soil, a pot experiment was carried out at Department of Soil Science, Gomal University, Dera Ismail Khan (Pakistan). The detail of treatments are Control, inorganic fertilizer (NPK), Biochar, Compost, Farmyard manure (FYM) and poultry manure. The experiment was laid in randomized complete design. The result showed that various growth, yield and root parameters were significantly affected by the addition of organo - chemical amendments. Significantly, higher value for plant height and root length was recorded 33.95 and 23.99 cm for the treatment of compost and poultry manure respectively. The plant and root fresh and dry weight were non – significantly changed by the application of organo – chemical amendments. The yield parameters showed that number of pod per plant were non – significantly changed, however the nodule count, 100 grain weight and grain yield was significantly increased by the application of amendments. The highest nodule count was recorded in the compost treated pots, while both the 100 grain weight and grain yield was found maximum in the pots receiving commercial NPK fertilizer. Soil pH, Bulk density, Organic matter content were significantly improved by the application of treatments. Alkaline and Acid phosphatase assay showed increase in the activity of both enzymes by application of FYM and other organic and chemical amendments. Also, soil macro – nutrients NPK were significantly enhanced by addition of FYM and NPK. It may be concluded from this research that the organic amendments have significantly influenced the growth, yield parameter of Chickpea, soil properties and enzymes activities.
