Effect of micronutrient on yield and nutrient uptake in sorghum
SK Choudhary, MK Jat and AK Mathur
A field experiment was conducted during the rainy (kharif) seasons of 2010 and 2011 at Rajasthan College of Agriculture, Udaipur, to study the effect of micronutrients on yield and nutrient uptake in sorghum [Sorghum bicolour (L.) Moench]. The experiment consisted of 24 treatment combinations and replicated three times in split plot design. The results showed that methods of micronutrient application through combined soil+foliar spray significantly increased grain (14.15 and 12.13%), stover (10.75 and 8.60%) and biological yields (11.37 and 9.31%) over soil and foliar application, respectively. The results show that application of Fe+ Zn+ B along with RDF proved its superiority over rest of treatments, however, combined application of two micronutrients were also significantly higher over alone nutrient application. Combined application of micronutrient (Fe+ Zn+ B) was significantly increased grain (25.33 %), stover (15.44 %) and biological yield (17.42 %) over control. The combined applications of soil + foliar application significantly uptake of N, P & K by 14.12 & 11.75%, 13.98 & 10.86% and 12.33 & 9.57% over soil and foliar application, respectively. Improvement of N, P and K uptake with RDF+ Fe+ Zn+ B was noticed of 33.25, 33.14 & 18.51 per cent over control. Micronutrient significantly improvement of Zn, (47.90, 18.32 %) Fe (30.20, 16.11%) and B (25.60, 19.75%) uptake were also noticed with soil + foliar and (Fe+ Zn+ B) over control.
