A field experiment was conducted at Research farm of Central Soil and Water
Conservation Research and Training Institute, Research Centre, Bellary,
Karnataka State, India to know the effect of integrated nutrient management in
winter sorghumchickpea cropping sequence on rainwater conservation, nutrient
availability and crop productivity in deep black soils during winter seasons of
2005-06 and 2006-07. In sorghum block, treatment with 15 kg N throughLeucaena loppings
and 20 kg N through urea(T8 ) recorded significantly higher
sorghum grain yield by 64% during 2005-06 (2200 kg ha-1) and in the pooled data
(1486 kg ha-1) over control. Greater grain yield in T8 was attributed to higher dry
matter accumulation in head with greater head weight, grain weight per plant,
1000grain weight and higher soil moisture and nutrient availability. During 2006-07, application of N through organic amendments alone conserved the lower
annual and crop season rainfall thus producing 67% higher sorghum yields i.e.,
792 kg ha-1 with application of 15 kg N through farmyard manure + 10 kg N
through Leucaena loppings(T9 ) over control. Application 15 kg N throughLeucaena loppings
and 20 kg N throughurea (T8 ) produced significantly higher
water use efficiency (WUE) of 8.14 kg ha-1 mm-1 and lower WUE of 5.22 kg ha-1
mm-1 in control. In chickpea block also, significantly higher grain yield of 1035 kg
ha-1 and 1001 kg ha-1 was observed in T8 treatment and application of 15 kg N
throughLeucaena loppings and 10 kgNthroughurea (T7 ) and were higher by 87%
and 81%, respectively over grain yield of 554 kg ha-1 produced in control. Higher
nutrient availability in T8 and T7 produced more pods per plant with greater dry
matter accumulation in pods thus resulting in higher grain and straw yields. Even
significantly higherWUEof 6.16 and 6.00 kg ha-1 mm-1 was observed in T8 and T7
respectively over lower WUE of 3.69 kg ha-1 mm-1 observed in control plots in
chickpea block. In sorghum and chickpea strip cropping block also, higher
sorghum grain equivalent (SGE) of 1757 kg ha-1 was observed in T8 treatment and it
was higher by nearly 45% over lower SGE of 1211 kg ha-1 produced in control.
Higher SGE in T treatment was attributed to production of higher grain and straw
yields of sorghum and chickpea in strips with greater soil moisture and nutrient
availability. It can be concluded that application 15 kg N throughLeucaena loppings
and 20 kg N through urea(T8) resulted in greater soil moisture
conservation with higher nutrient availability thus producing significantly higher
sorghum and chickpea yields during winter season in deep black soils of Bellary.
