Influence of Enriched Pressmud Compost on Soil Chemical Properties and Yield of Rice

D. Kalaivanan and K. Omar Hattab

Abstract:
A field experiment was conducted to investigate the effect of enriched pressmud compost on soil chemical properties like pH, EC, major nutrient availability and yield of rice with five levels of pressmud compost viz., 0, 1.25, 2.50, 3.75 and 5.0 t ha-1 in two varieties viz., ADT 36 and ADT 43 and a hybrid ADTRH 1 during the kharif season of 2004 in the farm soil of Pandit Jawarhalal Nehru College of Agriculture and Research Institute, Tamil Nadu Agricultural University (TNAU). The results of the field experiment revealed that the hybrid ADTRH 1 manifested higher grain and straw yield, whereas, the variety ADT 43 and ADT 36 registered lower grain and straw yields, respectively. With regard to the enriched pressmud compost, the application of 1.25 t ha-1 of enriched pressmud compost showed its potentiality by providing more available nutrients to promote higher grain yields and it was comparable with 2.50 t ha-1 of enriched pressmud compost. However, the straw yield was higher with 2.50 t ha-1 of enriched pressmud compost and it was on par with 1.25 t ha-1 of pressmud compost. The soil reaction (pH) and Electrical Conductivity (EC) did not show any marked variation with application of enriched pressmud compost. The N, P and K availability in soil was at higher levels and comparable with application of 1.25 and 2.50 t ha-1 of enriched pressmud compost, whereas it was lower with control. The outcome of the present investigation revealed that the highest grain yield was obtained, at 1.25 t ha-1 of enriched pressmud compost along with inorganic fertilizers for the varieties and hybrid. Hence, the incorporation of 1.25 t ha-1 enriched pressmud compost as basal along with required remaining nitrogen through inorganic fertilizer as top dressing in three splits may be recommended for rice crop to realise maximum yield in kuruvai (Kharif) season.
