Response of winter maize yield to summer legume and non-legume green manuring - Kathmandu (Nepal) NARC|CIMMYT : 2002 - P. 196-199 - Printed
A field experiment was conducted to determine the residual contributions of summer legumes and non-legumes as green manures and application of traditional farm waste and farmyard manures to winter maize production in the year 2000 and 2001 summer and winter seasons at the National Maize Research Program farm Rampur. The residual effect of in situ green manuring using five summer legumes, two non-legumes and application of 10 t/ha farm waste and farmyard manures was significant in increasing the winter maize grain yield. Maize that was planted 40-45 days after the incorporation of sunhemp biomass produced the highest maize grain yield (4.223 t/ha) followed by Sesbania green manuring (3.591 t/ha). The response to maize yield through green manuring with soybean, cowpea, sesame, maize and farm waste manuring was low and non-significant compared to sunhemp, Mucuna, and Sesbania. But the maize dry matter production that was added to soil was found to be higher. The lowest maize yield was found on the fallow treatment (control). These results showed that the increased winter maize yield was the contribution of dry matter and symbiotically fixed nitrogen by the summer green manure legume crops. A significant interaction was also observed between the year and treatment.
