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.

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.

This experiment was carried out during 2019 cropping season to evaluate the effect of cow dung rates and Sasakawa technology on the performance of maize in Mubi, Northern Guinea Savannah at Food and Agricultural Organization Tree/Crop production farm Adamawa State University, Mubi. The trial was laid out in Randomized Complete Block Design replicated three times. Data was collected on fifteen characters namely: Number of leaves at 3,6 and 9 weeks after sowing also Plant height at 3,6 and 9 weeks after sowing, Cob length, Number of row per cob, Number of seed per row, Cob diameter, Cob yield, Shelling percentage, Grain weight, Grain yield and 100 Grain weight. Results showed a non-significant difference for all the fifteen (15) traits of maize T1 but T4 have better performance. Also, NL3 and NL6, T3, T4 and T5 outperformed in terms of yield, NL3 showed a highly significant positive correlation with NL6, NL9, PH3 and PH6. Cob yield also has slightly and significantly correlation with NL6, CL and NS/R. The treatments respond to variations in the rates of cow dung application during the trial period. As highly significant and positive correlation was observed for NL3, NL6, NL9, PH3, PH6, and PH9 indicating differences in the treatments applied. The experiment revealed that treatment T1, T4 and T1, T4 for NL3, and NL6 gave highest performance than other treatments, followed by T1 and T4 for NL9 which also did well in that order respectively. Cob yield was observed to performed better in T3, T4 and T5. That translates to a very good grain yields in T3 (27kg/ha-1), T4 (16.20kg/ha-1) and T5 (20kg/ha-1). This might be due to the rates of cow dung applied on these treatments. Hence, it is therefore recommended based on the results of the study to use these range of cow dung in the study area.  Further research is also recommended to be done in this area for adoption by farmers.

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.

The study was carried out to find out the effect of zinc (Zn) and boron (B) on growth and yield of okra (BARI Dherosh 1). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatments of the experiment were, T0 (without Zn or B), T1 (20 kg Zn ha-1), T2 (30 kg Zn ha-1), T3 (10 kg B ha-1), T4 (20 kg B ha-1), T5 (20 kg Zn ha-1 + 10 kg B ha-1), T6 (20 kg Zn ha-1 + 20 kg B ha-1), T7 (30 kg Zn ha-1 + 10 kg B ha-1) and T8 (30 kg Zn ha-1 + 20 kg B ha-1) were undertaken to evaluate the best results of the study. The highest plant height was found in T8 (30 kg Zn ha-1 + 20 kg B ha-1) but the highest number of leaves plant-1 was recorded from T7 (30 kg Zn ha-1 + 10 kg B ha-1). On the other hand, the maximum leaf area index, SPAD value, mean fruit weight, fruit length, fruit diameter, fruit dry matter (%), number of fruits plant-1, fresh fruit weight plant-1 , fruit yield plot-1 and fruit yield ha-1 were found in T7 (30 kg Zn ha-1 + 10 kg B ha-1), while the control (T0) showed lowest performance for the respected parameters. It is strongly concluded that 30 kg Zn ha-1 with 10 kg B ha-1 combination may be helpful for okra cultivation in the field level to increase okra production.

Field experiment was carried out during 2010 rainy season to find the effect of seeding rate on the growth and yield of okra (Abelmuschus esculentus) in Zuru Northern Guinea Savannah. Zuru is located in Zuru Local government area of Kebbi State (Latitude 11o 251 to 11o 551 North and Longitude 4o 51 to 5o 251 East of the equator). The experiment consisted of three treatments that is planting okra at one plant per stand (S1), two plants per stand (S2) and three plants per stand (S3). The experiment was laid out in randomized complete block design (RCBD) and the treatments replicated three time. The result of the experiment has shown that plant height and number of leaves/plant at 3, 6 and 9 weeks after planting (    WAP) were significantly influenced by seeding rate (P<0.05). At 3, 6 and 9 WAP tallest plants were obtained from okra plants planted at three plants/stand (27.83, 54.0 and 77.0cm) respectively followed by okra planted at two plant/stand (24.77, 50.67 and 74.33 leave/plant respectively ). However, more number of leaves/plant were obtained from okra plant at one plant/stand (9.67, 24.67 and 48.0 leaves/plant respectively) followed by okra planted at two plants/stand (8.33, 18.33 and 36.33 leaves/plant respectively). Seeding rate had significant influence on time of 50 percent flowering with one plant/stand first attaining 50 percent flowering stage just within 36.33 days followed by okra planted at two plants/stand (38 days). The mean fresh fruit yield of okra was also significantly influenced by seeding rate with the highest yield of fresh fruits obtained from three plants/stand (83.34/ha) followed by okra planted at two plants/stand (55.56/ha). However, the result of the findings recommends that, okra should be planted at two plants/stand for medium sized and marketable okra fresh fruits since at three plants/stand leads to the production of undersized fresh fruits which do not often attract customers. At one plant/stand, there seemed to be early fruiting and bigger sized fresh fruits but low total yield due to underutilization of land resource/space. Planting at one plant/stand should therefore be avoided

This study evaluates the growth performance of lettuce (Lactuca sativa L.) utilizing various fermented products as organic fertilizers. Growth performance is determined through the plant’s weight and leaves and significant differences in growth among various treatments: (a) fish trash, (b) scrap seaweeds, (c) kangkong, and control groups urea (positive) and water (negative) was also determined. Kangkong leaves are fermented for 10 days, fish trash for 14 days and 1 month for seaweeds. Lettuce seeds are sown before transplanting (15 days after germination) into pots and placed in raised beds. Randomized complete block design is utilized in the experiment. Growth performance is measured through the number of leaves 10, 20, and 30 days after transplant and mass of plant upon harvest. After 30 days, the lettuce was harvested. Based on the findings, the soil and fermented products are acidic and the needed organic matter for optimum growth of lettuce are not sufficient as well as some nutrients of the fermented products. Among the organic fertilizers, kangkong at 30 ml performs best in terms of the growth performance of lettuce. Urea performs best in terms of the mass upon harvest. Significant differences exist in the mean number of leaves of lettuce treated with various amounts of organic fertilizers with the plants that receive urea. Lettuce produce more number of leaves and with the highest mass upon harvest when treated with urea compared with organic fertilizers applied after 30 days from transplant.

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.
