Keywords: Maize  hybrids  ;  winter  season Abstract: National Maize Research Program (NMRP) has initiated research to identify suitable maize hybrids developed by multinational companies for general cultivation as short-tenn strategy using the fund of respective seed company in central and eastern Tarai since last three years. In the process of evaluation, NMRP has assessed 69 and 56 hybrids in 2011 and 2012, respectively from 12 multinational companies in collaboration with RARS, Parwanipur and RARS, Tarahara during winter cropping season along with two OPVs and one hybrid check. The experiment was carried out in randomized complete block design with two replications at both locations in Rice-Maize cropping system and three replications at Rampur in Maize-Maize cropping system. Plot size was four rows of 5 m lengths with 75 em x 25 em (RR x PP) spacing and 160:60:40 kg ha"1 NPK, respectively. Five hybrids from three multinational companies and 11 hybrids from six multinational companies were registered in 2010 and 2011, respectively based on the infonnation provided by the respective seed company. Sixteen hybrids from twelve multinational seed companies were registered in 2012 based on the results of collaborative experiments conducted by National Maize Research Program.

Languages : English (eng) Keywords: fertilizer  and  manures;  grain  yield;  maize  genotypes  significant  effect. Abstract: The development of agronomic practices in terms of ‘maize genotypes and nutrient management’ is essential for enhancing maize productivity. In order to identify and evaluate suitable rates of fertilizers (NPK and farmyard manures) to different maize genotypes, field experiments were conducted at Rampur, Chitwan during the winter season of 2009/10 and 2010/011. Five levels of fertilization; (1) Control (zero fertilizer), (2) Farm yard manure (FYM) 10 t ha-1, (3); 60:30:20 N, P2O5 and K2O plus FYM 10 t ha-1; (4) 120: 60: 40 N, P2O5 and K2O plus FYM 10 t ha-1; (5) 180: 90: 60 N, P2O5 and K2O kg ha-1 plus FYM 10 t ha-1 and (6) 120: 60: 40 N, P2O5 and K2O kg ha-1 ) applied to four maize genotypes (Rampur Composite, Manakamana-4, Across9942 / Across 9944 and S99TLYQ-B) in the experiment. The experiment was laidout in a factorial RCB design with three replications. The plot size was 12 sq. m (4 m x 3 m) and the crop was planted in the month of October and harvested in April. The results revealed that most of the growth and yield parameters were found significantly increased with increased level of fertilizers (180:90:60 kg N, P2O5 and K2O plus 10 t of compostr ha-1) in Rampur Composite, Manakamana-4 and Across 9942 / Across 9944 where as these parameters were significantly increased in S99TLYQ-B variety with the fertilization level of 120: 60: 40 N, P2O5 and K2O plus FYM 10 t ha-1. Highest grain yield (6068 kg ha-1) was recorded in the year 2009/010 when fertilized by 180: 90: 60 N, P2O5 and K2O plus FYM 10 t ha-1 irrespective of the genotypes, and 4882 kg of grains produced by Rampur composite variety in this year irrespective of the fertilizer levels. Two years mean yield results revealed that varieties such as Manakamana-4, Rampur composite and Across 9942 / Across 9944 produced highest grain yield (5074 kg, 5195 and 5052 kg grains ha-1, respectively) with N, P2O5 and K2O at 180: 90: 60 kg ha-1 plus FYM 10 t ha-1.This paper discuss and highlights the results of fertilizer and manures application on different maize genotypes in detail.

Chaudhary, Author ; Akhtar, T., Author ; M. Tripathi, Author ; Bhurer, K.P., Author Publisher: Hardinath, Janakpur : National Rice Research Programme Publication Date: 2010 Pagination: 115-124 p. Abstract: The research works for varietal development were carried out with the objective to identify high yielding genotypes having less cold injury at seedling stage in boro rice at NRRP, Hardinath and Rangeli, Morang during 2004/05-2005/06. A total of 49 entries including checks were tested in BON in 2001/02. Among them, IR623-249-2-3-2-3 (4805.3kg/ha). IR6562-116-2-3-2-3 (4500.8 kglha), IR 12101-4-159-1-3-3(4678.5kglha), IR 71604-4-17-10-2-1-3 (4668.5kglha), IR71606-2-1-1-1~1-3-3-l-2 (4559.5kglha), IR71606-l-1-4-2-3-1-2 (4500.1 kglha), IR69707-101-2-2-3-3 (4705.5 kglha), IR 73888-1-2-7 (4530.25 kg/ha)IR 73887-1-9-1-5 (4575kglha), IR 656220-192-3-3-3-2(4635.65 kglha) produced higher grain yield kg/ha with better phenotypic acceptance followed by Check Jaya (4461.88 kglha). Out of21 entries including checks, 15 were found having higher grain yield with less cold injury in NRBON during 2002/03. All the tested gen!)types in CVT-boro were found significantly different in respect to days of heading, maturity, plant height, panicle length, paniclelm2 and grain yield kglha, in 2002/03. Similarly in CFFT-boro; the tested genotypes Gautam, Dhanlaxmi, Prahbat, and Saroj gave higher grain yield of 4298, 3039, 2700 and 2654k~a respectively. Out of 30 entries, 17 produced higher grain yield over checks in NRBON during 2003/04. Of them, Biplov (4644.74 kglha), BR-35 (4868.80kglha), BR-36 (5185.6kglha) Khumal-11(5220.77kglha) and Shahibalam (4408.,8 kglha) were had higher grain yield than others in CVTboro during2003/04. The tested genotypes in CFFT-boro; Khumal-11(4916.53 kglha), Saroj (4509.3kglba), Jaya (45977 kglha and Gautam (4480.67 kglha) recorded higher grain yield followed by Radha-4 (4055.33 kglha) in 2003/04. However, Saroj was preferred by farrmers due to earliness and good quality of beaten rice (Chiura).
