Description |
Field experiments were conducted to study the response of different maize hybrids to varied fertility levels in vertisol under irrigation at Agricultural Research Station Mudhol, Karnataka state during kharif (rainy) seasons of 2010 and 2011. Treatments consisted of three maize hybrids (QPM-1, Pinnacle and Arjun) in main plots, three NPK levels (100%, 150%, and 200% of recommended dose) in sub plots and sulphur levels (20, 30, 40kg/ ha) in sub-sub plots. After harvest of first year, the treatments were subjected six storage treatments (cow dung ash @ 30%, wood ash @ 30%, Diatomaceous Earth @ 0.3%, Nimbecidine @ 1%, sweet flag @2% and control). Among the three hybrids studied, Pinnacle receiving 200% NPK together with 40 kg sulphur ha-1 recorded significantly higher grain yield (13200 kg ha-1), net returns (Rs.119100 ha-1) and B:C (3.81) while QPM-1 in general, produced the lowest grain yield (8046 kg ha-1), net returns (82190) and B:C (2.61) compared to other treatment combinations and was followed by 30 kg S (12190 kg ha-1) by the same hybrid with similar NPK levels. Higher amount of nitrogen and potash were taken up at 200% NPK along with 30 or 40 kg sulphur whereas higher uptake of phosphorous was seen at 200% NPK with 30 kg sulphur. Highest uptake of sulphur was noticed with application of 40kg sulphur along with 200% NPK. In the storage study, the highest weight loss of grains was recorded when maize grains were stored without any storage treatment (28.30%) and the lowest loss was recorded in sweet flag (5.07%) followed by diatomaceous earth (5.32%), nimbecidine (5.60%), cow dung ash (5.92%) and wood ash (6.17%) in all hybrids grown under different NPK levels and storage treatments. However, the storage treatments did not have any significant effect between fertility levels and maize hybrids. |
