| dc.description.abstract | Integration of organic and inorganic sources of nutrients can sustain crop yield and fertility in a much better way than their sole application. It also facilitates recycling of farm products to reduce the cost of production and pollution to some extent. Thus, keeping these objectives in a view, wheat-forage maize sequence under nine integrated nutrient management treatments (100% NPK through fertilizers, 50% NPK through fertilizers + 20t FYM/ha, 50% NPK through fertilizers + 10 t poultry litters/ha, 50% NPK through fertilizers + 20 t piggery manures/ha, 50% NPK through fertilizers + 20 t subabool leaves/ha 75% NPK through fertilizers + 101 FYM/ha, 75% NPK through fertilizers + 5 t poultry litters/ha, 75% NPK through fertilizers + 10 t piggery manures, 75% NPK through fertilizers + 101 subabool leaves/ha) were taken in randomized block design replicated thrice. The experiment was laid down during kharif 1995 as a permanent manurial trial under AICRP on forage crops (ICAR) and thus the present observations were taken during 3rd year Rabi (1997-98) and 4th year kharif (1998) seasons. The soil of the experimental plots were silt loam in texture (sand 37,27%, silt 51.20%, clay 11.63%) was low in organic carbon, available N, P and medium in K with pH 6.1. Results of 3rd and 4th year investigation revealed that organic matters in general and piggery manures and poultry litters in particulars were found more efficient in obtaining grain and forage yields, maintaining soil fertility and relatively more economical Accordingly, application of 10 t poultry litters/ha or 20 t piggery manures/ha with 50% NPK through fertilizers as well as the quantity of these two organic sources by half + 75% NPK through fertilizers were found equally good for wheat production while 10 t poultry litters or 20 t piggery manures + 50% NPK through fertilizers produced the maximum forage maize yield. These two treatments were found statistically equally remunerative for total production round the year Though, under all the fertility treatments, an increase in organic carbon as compared to initial value was noticed however, it was found maximum when the soil was treated with poultry litters @ 10 t/ha (0.600 %) or 5 t/ha (0.595 %). Alike to organic carbon, an increase in soil-N above initial status (220 kg N/ha) under all the treatments was analysed with relatively higher in organic matter treated plots. Crop grown in presence of either levels of poultry litters or piggery manures were found more effective in raising available soil-P status. A general reduction in soil-K reserve was noticed under all the fertility management systems to their initial value (144.8 kg/ha) due to luxuriant use of this nutrient by both crops followed by washing out of the same under heavy rainfall conditions: | |
