Yield maximization in cotton through targeted yield approach and omission plot techniques in Vertisols of Karnataka
A study was undertaken in the Bt cotton growing farmer fields of Raichur district with the following objectives 1. To know the effect of targeted yield approach on growth, yield and quality of Cotton in Vertisols 2. To study the effect of fertilization on crop nutrient uptake, soil nutrient status, nutrient balance sheet and efficiency of applied fertilizers 3. To workout the economics of cotton cultivation under fertilization levels and omission plots

The current project was aimed at assessing the yield responses to application of nitrogen, phosphorus and potassium (NPK) in transgenic cotton grown in the black soils of northern Karnataka. The on-station replicated experiment was conducted at the agricultural research station at the University of Agricultural Sciences, Dharwad, Karnataka. Cotton was grown under a rain-fed environment with the support of supplemental irrigation during the monsoon season of 2017. Read more

The current project was aimed at assessing the yield responses to application of nitrogen, phosphorus and potassium (NPK) in transgenic cotton grown in the black soils of northern Karnataka. The on-station replicated experiment was conducted at the agricultural research station at the University of Agricultural Sciences, Dharwad, Karnataka. Cotton was grown under a rain-fed environment with the support of supplemental irrigation during the monsoon season of 2017.
A replicated on-station study on cotton was undertaken at the research farm of the University of Agricultural Sciences in Dharwad (northern Karnataka) during the monsoon season of 2016. The objective of the study was to assess the contribution of nitrogen (N), phosphorus (P), and potassium (K) towards the yield of Bt cotton, determine the nutrient uptake, and to work out the extent of economic loss due to the omission of major nutrients as compared to the fully fertilized plot.
