Title : Evaluation of soil properties and wheat (Triticumaestivum L.) productivity influenced by nitrogen levels and sowing dates under zero tillage condition in Chitwan, Nepal Material Type: printed text Authors: R.B Mahato, Author ; K.R Pande, Author ; Regmi, A.P., Author Pagination: 53-61 p. Languages : English (eng) Keywords: Chlorophyll value, grain yield nitrogen levels phosphorus uptake sowing dates zero tillage. Abstract: An Experiment was conducted on a farmer field at Torikhet Chitwan, Nepal, during 2011/2012 in order to know the soil properties and wheat productivity influenced by nitrogen levels and sowing dates under zero tillage. The experiment consisted four nitrogen levels (60, 100, 140 and 180 N kg ha-1) and three sowing dates (Nov. 25, Dec. 10 and Dec. 25) and laid out in split plot design. The plant characters, soil physical and chemical properties, yield attributes and yields were significantly influenced by different treatments. The result showed that the highest grain yields (4.84 t ha-1 and 4.97 t ha-1, respectively) were obtained from the crop sown on Nov. 25 and from the application of 140 N kg ha-1. The highest chlorophyll value was recorded on the crop sown on the same Nov.25 and from the application of 140 N kg ha-1. Nitrogen dynamics including total nitrogen uptake, total soil N, residual N and unaccountable N were found highest on the crop sown on Nov. 25 and from the application of 180 N kg ha-1 but was the lowest (30.59 N kg ha-1). The highest total phosphorus uptake, total soil phosphorus, residual phosphorus and unaccountable phosphorus were observed on the crop sown on Nov. 25. The net income were highest (NRs. 49,640 ha-1 and NRs. 52,510 ha-1, respectively) on the crop sown on Nov. 25 and from 140 N kg ha-1.

Title : Carbon dioxide emission from soil grown to wheat crop at Khumaltar, Lalitpur Material Type: printed text Authors: S Kandel, Author ; S.C Shah, Author ; Gautam, A.K., Author ; K.R Pande, Author Pagination: 412-420 p. Languages : English (eng) Keywords: Carbon dynamics,CO2 emission, mulching, zero tillage. Abstract: Changes in farming practices could be an effective way to reduce carbon (CO2-C) emissions from agricultural lands thereby sequestering more carbon in the soil. A field experiment was conducted on an acidic silt loam upland soil of Khumaltar, Nepal during the dry season of 2011/2012. The study evaluated soil CO2 - C emission from a wheat field as influenced by tillage, mulch, and nitrogen (N) application. The factorial experiment laid-out on a split-split plot design consisted of three replications of 12 treatment combinations, i.e., two types of tillage (zero and conventional) on a main-plot, two levels of mulch (zero and 4 t ha-1 of rice straw) on a sub-plot and three levels of N application (zero, 100 and 150 kg ha-1) on a sub-sub plot. The crop growing season in this region is relatively longer primarily due to the effects of low temperature and high elevation (1300 masl); therefore, wheat (var. WK-1204) planted on December 6 of 2011 matured in six months (harvest date June 2 of 2012)………………..

Title : Evaluation of different methods of wheat establishment under excessive moisture condition Material Type: printed text Authors: Khan, S.U., Author ; N.K Bista, Author ; J.P.L Shrivastav, Author ; G.P Paudel, Author Pagination: 254-257 p. Languages : English (eng) Keywords: Zero Tillage, Relay Planting Abstract: Farmers are experiencing labor and time shortage during wheat sowing as there is less turnaround time between rice harvest and wheat sowing. This study was conducted to find out alternative of traditional tillage method of wheat sowing. Traditional tillage method, relay, surface, zero tillage and power tillage wheat sowing were evaluated. Alternate wheat sowing has created better conditions for water and weed control and allows 20-30 days earlier sowing of wheat and reduced the inherent drudgery in traditional wheat sowing. Farmer's tillage practice is labor intensive, costly and requires about 5-6 times plowing at sowing time and often result in delay sowing of wheat. Mean wheat grain yield under relay, surface, power tillage and zero tillage was more (about 21%) than farmer's tillage method.........................
