Abstract
The field experiment
was conducted during Rabi season 2015-16 and 2016-17 in Sultanpur
diatrict, U.P. The treatments included System of Wheat Intensification (SWI)
technique, Kera method and Furrow Irrigated Raised Bed (FIRB). The results
revealed that soil pH and electrical conductivity remained within the normal
range and were not significantly affected by the planting methods. However, SWI
recorded comparatively lower EC and pH values closer to neutrality. Organic
carbon content improved from the initial values (0.40 to 0.46%) and increased
by about 9.30% under SWI and
Kera method in pooled analysis. Similarly, improvement in soil nutrient status
was observed after harvest. Under SWI, available nitrogen, phosphorus, and
potassium increased by 8.03%, 16.16%,
and 5.43%, respectively in pooled, over the initial soil status.
Micronutrients also showed improvement, where sulfur, zinc, iron, manganese,
copper, and boron increased by 2.52%, 4.60%,
3.21%, 3.57%, 10.87% and 4.84%, respectively in pooled. Application of
different organic nutrient sources also influenced the soil chemical properties
and nutrient availability after harvest of wheat. The treatments consisted of
poultry manure (2.6 t/ ha), farmyard manure (16 t/ ha) and Bokashi manure (3.2
t/ ha). Soil pH and electrical conductivity remained within safe limits with
all organic nutrient sources. Among the treatments, farmyard manure (16 t/ ha) recorded comparatively lower EC and pH
values closer to neutral and significantly improved soil organic carbon, which
increased by 9.30% in pooled
over the initial soil organic carbon status. The availability of major
nutrients such as nitrogen, phosphorus and potassium also increased with the
application of farmyard manure by 9.31%,
18.69% and 5.68%, respectively in pooled, compared with the initial soil
status. Similarly, micronutrient availability improved, where sulfur, zinc,
iron, manganese, copper, and boron increased by 2.79%, 4.60%, 3.33%, 4.02%, 10.87%, and 4.84%, respectively in
pooled.
