Response Of Maize Varieties To Sowing Dates In Inner Terai Region, Dang, Nepal

AbstractSowing dates and varieties affect the productivity of maize. A field experiment was conducted to find out the response of maize hybrids to sowing dates on growth and productivity of maize in spring season at Lamahi, Dang in 2019. The experiment was laid out in two factor factorial Randomized Complete Block Design with four replications. The treatment consisted of combination of three different sowing dates (February 1, February12 and February 23) and two maize varieties (Arun-2 i.e. OPV and hybrid Bioseed-9220).The result revealed that earlier planting on February 1 produced the highest yield (8265 Kg ha-1) which was significantly superior than latter planting of February 12(6099 kg ha-1)and February 23 (5934 kg ha-1).The higher yield in earlier planting was due to significantly higher no of kernel per ear, non-significant but higher number of cob per unit area, thousand grain weight. Similarly, Bioseed 9220 produced higher yield (7798 kg ha-1) compared to Arun-2 (5,734 kg ha-1). The higher yield of hybrid Bioseed 9220 was because of higher number of cob per unit area harvested and more number of kernel per cob. Therefore, earlier planting with hybrid maize is recommended in spring season of Dang and locations with similar climatic conditions for higher productivity of maize.

Five maize varieties namely Rampur composite, Arun-2, Manakamana-3, Rampur Hybrid-4 and Rajkumar were evaluated in randomized complete block design with four replications at farmers field at Nilkantha Municipality-09, Aashikhola, Dhading from February 2018 to June 2018 to identify high yielding maze varieties. Significant variation was observed for grain yield, silking and tasseling, number of kernels per cob and cob length.The largest cob length was found in Rampur composite (19.550 cm) and highest number of kernel row per cob was found in Rajkumar (17.25) and Manakamana-3 (17.25).The highest number of leaves above cob was found in Rampur composite (5.678). The number of days for 50% tasseling and number of days for 50% silking had a highly significant and positive correlation with plot yield. The highest number of days for 50% tasseling (78.50 DAS) and days for 50 % silking (82.50 DAS) was observed in the genotypes Rampur Hybrid-4. Similarly, the number of leaves above the cob , thousand kernel weight and length of the cob had a significant and positive correlation with plot yield. Rampur Hybrid -4 was the highest yielding genotype (7.79 t/ha) for such domain area with a B:C ratio of 1.48.Thus, Rampur Hybrid-4 genotype is recommended for spring season in Dhading.

Superiority of hybrid maize cannot be overemphasized. Different types of hybrids are developed by plant breeders to improve productivity and multi-locational evaluation of these hybrids prior to release is necessary to select the best. The objectives of this study were to identify maize hybrids with superior agronomic potentials and compare the performance of top-cross and three-way cross hybrid maize varieties for grain yield and related traits under rain-fed condition in three different locations (Abeokuta, Ibadan and Akure) of Southwest Nigeria. The study consisted of ten hybrids each of top-cross and three-way cross hybrid varieties, tested with two checks. At each location, the experiment was laid out in randomised complete block design with three replications. The results showed that effects of locations, genotypes and genotype x location interactions were highly significant (p<0.01) for all the traits evaluated. Significant differences were also revealed between the top-cross and three-way cross hybrids for all the traits evaluated except days to 50% tasseling, ear diameter and 100-grain weight. The top-cross hybrids were superior over the three-way cross hybrids for grain yield by 5.25%. The hybrids ‘M0926-7’, ‘M0926-8’, ‘M1026-11’, ‘M1026-3’, ‘M1226-2’ (top-cross hybrids), ‘M1124-24’, ‘M1124-27’, ‘M1124-31’, ‘M1227-6’ and ‘M1227-7’ (three-way cross hybrids) showed highest stable yields across the three locations. Hybrids ‘M0926-7’ (top-cross hybrid) and ‘M1124-24’ (three-way cross hybrid) that expressed early flowering with higher grain yield are recommended for drought stress prone areas because of their abilities to tolerate drought through escape.

Development of maize varieties tolerant to drought is very important to extensification program in dry maginal lands, especially outside Java. The research objective was to evaluate the agronomic performance, genetic variabilities and heritabilities of hybrid maize top crosses at Probolinggo and Gowa during dry season. A randomized complete block design with two replications was applied to each location. The combined analysis of variance showed that hybrid x location interaction was significant for harvesting date, corncob length, 1000 grain weight, and highly significant for flowering date, leaf curling, husk cover aspect, corncob aspect, plant harvested, weight of corncob harvested and grain yield. The genetic variance was considered broad for grain yield, weight of corncob harvested, shalling percentage, number of grain rows per corncob, and corncob aspect. Heritability values in combined location analysis were high for shalling percentage; medium for grain yield, weight of corncob harvested, shalling number of grain rows per corncob and corncob aspect; but for the other characteristics they were low. Low selection intensity (≥ 10%) can be applied in this generation (S2), but strong selection intensity (≥20%) can be applied in the next generation (≥S3).

An on-farm trial was conducted over a 2-year period in Tibali in the Savelugu district of Northern region of Ghana to evaluate the productivity and economic returns of hybrid and open pollinated maize (OPV) either in pure stands or intercropped with erect and trailing cowpea. The maize varieties used were medium maturing (110 days) whie the cowpea varieties were early maturiing (70 days). The experiment was conducted in a randomized complete block design with 14 treatments (sole pan53, sole Etubi, sole mamaba, sole obatampa, sole erect cowpea, sole trailing cowpea, erect cowpea + pan53, erect cowpea+etubi, erect cowpea+mamaba, erect cowpea+obatampa, traing cowpea + pan53, traling cowpea+etubi, trailing cowpea+mamaba and trailing cowpea + obatampa) replicated on 10 farms. Intercropping had better productivity and economic returns than sole cropping. Intercropping maize with trailing cowpea type had better productivity and economic return than intercropping with erect type of cowpea. Intercropping the OPV maize with cowpea had better productivity and economic return than intercropping hybrid maize with cowpea. Farmers may either intercrop OPV maize with trailing cowpea type or hybrid maize variety Pan 53 maize with trailing cowpea type for better productivity and economic return.

Maize is the second most important crop of Nepal. The yield of the crop is low due to lack of appropriate plant density for the varieties. The field experiment was carried out to study the effect of different row spacings on different maize varieties at Deupur, Lamahi municipality of the dang district in province No. 5, Nepal during the rainy season from June to September, 2018. Four levels of spacings (boardcasting and three row spacings of 45, 60 and 75 cm) and two maize varieties (Rampur Composite and Arun-2) were evaluated using randomized complete block design with three replications. The highest grain yield was found in Rampur Composite and Arun-2 while they were planted with row spacing of 60 cm with plant to plant spacing of 25 cm. The highest grain yield, cob length, cob circumference, number of rows per cob, thousand grain weight were reported when maize was planted in the row spacing 60×25cm. Among the maize varieties, Rampur Composite produced the highest grain yield, cob length, cob circumference, number of rows per cob as compared to Arun-2. This study suggested that maize production can be maximized by cultivating maize varieties with row spacing of 60 cm with plant to plant spacing of 25 cm.

Inappropriate seed rate and sowing method contribute a significant role in low productivity of sunflowers. So, a study was conducted to assess the effect of different seed rates and sowing methods on the yield of sunflower in Ghodaghodi Municipality ward no. 2, Sandepani, far-west province, Kailali, Nepal, during spring season in 2018. The three different seed rates (8 Kg/ha, 10 Kg/ha and 12 Kg/ha) combined with three different sowing methods (broadcasting, line sowing and ridge sowing). A randomized complete block design in a 3×3 factorial arrangement with three replicates per treatment was applied. The indigenous variety of sunflower was used as a test crop. The highest stem diameter was recorded with the lowest seed rate, which remained unaffected by different sowing methods. Head diameter, seeds per head and thousand-grain weight were maximum in plants receiving seed rate of 8 kg/ha. However, the highest (2.13 t/ha) and the lowest (1.76 t/ha) grain yield were achieved with the seed rates of 10 kg/ha and 12 Kg/ha, respectively. Regarding sowing methods, head diameter, seeds per head, thousand-grain weight and grain yield (2.68 t/ha) obtained in the ridge method were statistically superior over those, obtained in line and broadcasting methods. The interaction effect of seed rate and sowing method on seeds per head suggested that maximum seeds per head were obtained with 8 kg/ha seed sown in the ridge. Our study recommended 8 kg/ha seed rate and ridge sowing of sunflower performed best in grain yield.

We investigated the interaction between genotype by trait, and an experiment was conducted at the University of Debrecen. Two maize cultivars, FAO340 and FAO410, were studied in a randomized complete block design with four replications. This experiment was applied to the six fertilization treatments. Fertilizer levels were NPK0 (control) (N:0, P2O5:0, K2O:0), NPK1 (N:30, P2O5:23, K2O:27), NPK2 (N:60, P2O5:46, K2O:54), NPK3 (N:90, P2O5:69, K2O:81), NPK4 (N:120, P2O5:92, K2O:108), and NPK5 (N:150, P2O5:115, K2O:135). The first principal component showed 54.24%, and the second principal component showed 20.75%, which explained the total squares interaction using the AMMI model in the case of the FAO410 hybrid. As regards the FAO340 hybrid, the first principal component showed 58.18%, and the second principal component showed 18.04%, explaining the total squares interaction using the AMMI model in the FAO410 hybrid. In the GGE biplot on FAO410, the first and the second principal components covered 91.20% of the total data in this analysis. Accordingly, the desirable treatment was NPK5, followed by NPK4, NPK2, NPK3, NPK1, and NPK0. NPK4 and NPK5 had the most desirable treatments for the number of seeds per row, chlorophyll, weight of 1000 seeds, and stem diameter in the case of the FAO410 hybrid.

Boro rice (grown in winter under irrigated condition) contributes to the major portion of rice production (over 50%) in Bangladesh. Binadhan-17 is a green super rice developed by BINA which requires 30% less nitrogenous fertilizer and water which is grown in aman season (primely produced under rainfed). Due to it’s increasing popularity and adoption rice growers are keen to cultivate it in boro season also. Taking account of the above situation, two field trials were conducted at Magura during November 2019 to May 2020 to investigate the effect of variety, sowing dates and their interaction. Factorial RCBD (Randomized Complete Block Design) was applied for experimentation. Two rice varieties: Binadhan-17 (V1), BRRI dhan58 (V2) and three sowing times: 30th November (T1), 10th December (T2), 20th December (T3) were used as treatments. 35 days old seedlings were transplanted in main field. Relevant agronomic and morphological data were statistically analyzed through Statistix 10.0. Combined effect of the above factors at farm exposed that, T1×V1 required longest days (159.33 days) to mature. but, comparatively short life cycle (149.97 days) was observed by T3×V2. Maximum grain was yielded (7.70 t/ha) by T2×V1 and minimum (5.74 t/ha) by T1×V1 treatment combination. Outcomes of on station revealed that, T1×V1 needed more days (158.00 days) to mature; conversely, alike duration was noted with T2×V2 (147.20 days) and T3×V2 (145.43 days) which matured quite earlier. T2×V1 produced the highest grain yield (7.41 t/ha) and T1×V2 the lowest (5.94 t/ha). Our results indicate that, planting of Binadhan-17 on 10th December may give insect-disease free grains with optimum yield in context of Magura region. Farmers will be financially benefited if they cultivate this variety in the boro season in lieu of aman; due to higher yield

Abstract The experiment was carried out according to the randomized complete block design (R.C.B.D) and the arrangement of split-split plot with three replications, at the Field Crops Research Station of the Agricultural Research Department - Abu Ghraib during the spring season for the years 2019 and 2020. With the aim of studying the effect of amino acids, planting dates and their effect on some of the yield characteristics and its components for three varieties of maize in the spring season. Planting dates (March 15, March 25 and April 5) occupied the main plots, while amino acids and the control treatment (proline, arginine, and distilled water) occupied the sub-plot, whereas the varieties (Rabi, Baghdad 3 and Fajr 1) occupied the sub-sub-plot, and the most important results were summarized as follows:The two cultivars, Rabi and Fajr-1, achieved a significant increase in most of the yield characteristics and its components for the seasons. The addition of the amino acid proline also led to a significant increase in most of the studied traits (the number of grains in ear, weight of 500 grains, total grain and biological yield, and harvest index), planting dates also have a significant effect on most of the studied traits. The first date (15/3) recorded increase in the number of grains per ear, the weight of 500 grams, and the grain and biological yield. The plants of the Rabi variety when cultivated on March 15 th and sprayed with the amino acid proline achieved the highest average for the grain yield, which reached 7.48 ton. ha-1 for spring 2019.
