Abstract:

A Field experiment was conducted in a fine loamy mixed Hyperthermic Typic Haplustept soil to study the effect of fly ash and FYM on yield of rice and on cracking pattern of soil. The grain and straw yield of rice was significantly increased with fly ash, FYM and their interactions. The highest grain (5.84 t ha-1) and straw yields (7.87 t ha-1) were recorded by combined application of fly ash at 10 t ha-1 and FYM at 10 t ha-1 which was on par with fly ash at 15 t ha-1 along with FYM at 10 t ha-1. Application of fly ash and FYM has resulted in lesser number of cracks with more width and depth when compared to control. Study of cracking pattern of the field after crop harvest indicated that the number of cracks (29.33 m-2) were lowest and the width of cracks (3.67 cm), depth of cracks (l0.57 cm) were highest in FA15 FYM10 followed by FA10 FYM10 (38.67 m-2, 2.87 cm, 8.7 cm, respectively) when compared to control (FAo FYMo) (96.67 m-2, 0.78 cm, 3.57 cm, respectively). The aggregate stability studied in terms of per cent aggregates > 0.25 mm in diameter (55.60) and mean weight diameter (1.7) were highest in FA15 FYM10 followed by FA10 FYM10 (53.40 and 1.95 respectively) when compared to control (43.63 and 1.79, respectively).
