Title : Long term fertility trial on maize toria rotation Material Type: printed text Authors: Srivastava S.P., Editor ; Neupane D.D., Author Pagination: 165-174 p. Abstract: Response of the ·first crop (maize) to the treatments
(manure, lime and fertilizers) under study was found
non-significant. However,- from the second crop (toria)
and third crop (maize) to eighth crop· (toria) and nineth
crop (maize) a significant response to the applied
manure, lime and fertilizers was detected. But in
comparision with the first year tQ.e grain yield of maize
increased in the second year with all the treatments
under study except the control and 10 ton compost/ha,
whereas in toria the grain yield decreased with all the
treatments under study. From third year both maize and
toria have been showing a gradual decline in grain
yields during the ::;ucceeding years till eighth crop
(toria) and nineth crop (maize). The difference in
response to calcitic and dolomitic lime was found non
significant.Link for e-copy: http://elibrary.narc.gov.np/?r=631 Long term fertility trial on maize toria rotation [printed text] / Srivastava S.P., Editor ; Neupane D.D., Author . - [s.d.] . - 165-174 p.

Title : Long-term fertility trial on maize-toria rotation at ARS, Rampur Material Type: printed text Authors: Srivastava S.P., Editor ; Neupane D.D., Author Publisher: Lalitpur : NARC Publication Date: 1998 Pagination: 136 -142 .p Keywords: Soil fertility; Rice; Maize; Soils Abstract: A long-term fertility trial was initiated in 1992 to study the effects of manures and fertilizers onthe productivity of maize-toria (mustard) rotation. The response of maize in the first year to the treatments under study (manure, lime and fertilizers) was found to be non-significant. However, from the second year the grain yield of toria and from the third year the grain yield ofmaize were found to be consistently declining. From third year both maize and toria have beenshowing a gradual decline in grain yields during the succeeding years till 1998. The difference in response to calcite and dolomite lime was found non significant. Biotic and abiotcconstraints could be the reason for declining the yield of both crops. The sharp decline in thegrain yield suggests laboratory investigation and treatments modification.

Title : Response of summer legumes and non-legumes green manuring on winter maize yield Material Type: printed text Authors: Mahato, R.K., Editor ; Neupane D.D., Author ; Adhikari, K., Author ; S.P Shrivastav, Author Pagination: 262-268 p. Keywords: Hybrid ; maize genotype yield inbred Abstract: A field experiment was conducted to evaluaie the residual effect of summer legumes, r.onlegumes
as a green manures and application of traditional farm waste and farm yard manures
on the winter maize production in the year 2000 and 2001 summer & 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 tlha farm waste & form yard
manures was significant in increasing the winter maize grain yield. Maize that was planted 40-
.:/5 days after the incorporation of szmn hemp biomass produced the highest maize grain yield
(4.223 tlha) followed by sesbania green manuring. The response of mai~e yield to soyberm,
cowpea, sesame, maize and farm waste manuring was observed low and non significant
compared to szmn hemp, muczma, and sesbania. But maize d1y matter production and that was
added to soil was found 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 of green manures and symbiotically fixed nitrogen by the summer green manure legume
crops. A significant interaction was also oberseved between the year and treahnent.Link for e-copy: http://elibrary.narc.gov.np/?r=757 Response of summer legumes and non-legumes green manuring on winter maize yield [printed text] / Mahato, R.K., Editor ; Neupane D.D., Author ; Adhikari, K., Author ; S.P Shrivastav, Author . - [s.d.] . - 262-268 p.
