To study effect of sowing pattern and nitrogen on maize silage yield and its dependents components a trial was done at split-split plot design in compeletly randomized block at four replications in Qrakheil(Qaemshahr) agricultural research station in 2015 in Iran. Row spacing was chosen as main plots including: 65cm, 75cm and 85cm.Two cultivars (Sc704 and Sc770) in sub plots and three levels of N (250, 350 and 450 kg ha1) in sub-sub plots were laid out. Silage forage yield, ear and dry ear yield, leaf and dry leaf yield, plant dry weight and stem and dry stem weight,plant height , ear height,kernel number in ear row and row number in ear were measured.The results indicated that row spacing, were not affected on investigated traits. While nitrogen effected on silage yield, ear and dry ear yield, leaf and dry leaf yield, plant dry weight and stem and dry stem weight, plant height and ear height and showed significant difference. Sc704 had significant difference on plant silage weight, dry and wet stem weight with Sc770. Amount of 350kg/ha nitrogen was caused the most silage yield (36.74t/ha) and plant dry weight (16.64 t/ha) that had not significant difference with usage of 450kg/ha nitrogen(16.46 t/ha). Amount of 450kg/ha nitrogen was caused the most silage yield (37.30t/ha) that had not significant difference with usage of 350kg/ha nitrogen (36.74 t/ha). The most silage yield (38.21t/ha) obtained from Sc704 that was better than Sc770 (34.22 t/ha). The most plant dry weight (16.54) obtained from Sc704 that had not significant difference with Sc770 (15.92 t/ha).

SUMMARYMaize was grown al the Regional Agricultural Research Station, Hathazari, Bangladesh during 1988/89 and 1989/90 to study fodder yield, cob growth and grain yield together with the contribution of pre-silking stem reserves to grain. Population densities were 33300, 44400 and 66600 plants/ha. Plants were either detopped after silking and pollen shedding, keeping 0, 2 or 3 leaves above the cob, or were left entire.The results showed that the maize crop could successfully be detopped for fodder with little or no adverse effect on grain yield. Fodder yield increased with increased plant density and among the detopping treatments the highest fodder yield was obtained when the plants were detopped just above the cob. Cob growth followed a sigmoid pattern and the highest dry weight per cob was obtained from the lowest plant density and from entire plants. The number of cobs/m2 increased with increased plant density but detopping treatments did not give any significant difference in relation to densities. The number of grains/cob was highest with 33300 plants/ha but, among the detopping treatments, plants detopped just above the cob had the lowest number of grains/cob in both years. Weight of 1000-grain decreased with increasing plant density but it was increased by detopping plants just above the cob during 1988/89, although it was decreased in 1989/90. The highest apparent translocation of pre-silking reserves was obtained using densities of 44400 plants/ha but detopping treatments did not show any consistent effect, although the highest apparent translocation (20%) and harvest index (58%) were obtained from plants detopped just above the cob.

Aim: To study the grain yield performance of early maturity maize hybrid under rainfed conditions in relation to row arrangement, plant geometry and mulching. Place of Study: A field experiment was conducted at Agricultural research station, Karimnagar during kharif 2011-12. Methodology: The experiment was carried out in red sandy loam soils, in a split- split plot design with main plots as row arrangement (2) i.) Equal rows at 67cm ii). Paired row at 84: 50cm (Between and within paired rows), Sub plots as plant geometry (3) i.) with 40000 Plants/ha (intra row spacing of 37 cm) ii.) with 50000 Plants /ha (intra spacing of 30cm) iii.) with 60000 Plants/ha (intra row spacing of 25cm) and Sub- sub plots as mulching treatments (2) i.) without mulching ii.) with surface mulch @ 5 t/ha. The results indicated that there is no significant difference in grain yield of early maturity maize hybrid, when the crop is grown in equal row spacing of 67cm (5148 kg/ha) or paired row spacing of 84:50cm (4962 kg/ha). The grain yield of maize crop with 60000 Plants /ha (i.e., 25 cm intra row spacing) recorded higher grain yield of 5339 kg/ha followed by maize crop with 50000 Plant /ha (i.e., 30 cm intra row spacing) with 5097 kg/ha grain yield and 4729 kg/ha with 40000 Plant/ha (i.e., 37 cm intra row spacing). When crop rows were mulched with grass and dried weed material @ 5t/ha significantly increased the maize grain yield (5724 kg/ha) by 23 % than compared to the crop kept without mulch (4386 kg/ha). Consequently, the maize crop with surface mulching resulted in higher net returns (Rs.31770/ha) and benefit cost ratio of 1.7 over no mulching. While, the interaction for all parameters was non significant. Results: It can be concluded that farmers can either follow equal row spacing or paired row spacing based on situation, as there is no significant difference in terms of yield by either method. Mulching of inter row of maize crop under rainfed conditions has resulted in 23% increased yield than that of crop kept without mulch.

The coordinated varietal trial of quality protein maize was carried out in research station of regional agricultural research station, Doti during 2011/12 and 2012/13. A total of fourteen entries including standard and local checks were included in the experiment of both years. Out of tested entries of the year 2011/12, S99TLYQ-A produced the highest grain yield (2814 kg/ha) followed by SO3TLYQ-AB-01 (2765 kg/ha) and SO3TLYQ-AB-02 (2293 kg/ha). MSTATC software was used in data analysis. Flowering days, plant height and grain yield due to genotypes was found significant at 1-5% level. Amongst the tested entries include in the experiment of the year 2012/13, S99TLYQ-AB recorded the highest grain yield (6006 kg/ha) followed by SO3TLYQ-AB-01 (5409 kg/ha) and S99TLYQ-A (5330 kg/ha). There was significant difference in flowering days, plant height, ear height and grain yield due to genotypes at 1-5 % level. Combined analysis over year was also carried out. Genotypes SO3TLYQ-AB-01 (4087 kg/ha), S99TLYQ-A (4072 kg/ha) and S99TLYQ-AB (3750 kg/ha) identified as promising genotypes for lower hills and river basin agro-environment of far western hills. Similarly, experiment on selection of drought tolerance maize genotypes was also carried out at this research station during 2011/12 and 2012/13. Total 105 genotypes of maize were planted for selection of drought tolerance maize genotypes during 2011/12 and it was replicated twice. Quantitative and qualitative traits were recorded for screening against drought. Out of the genotypes included in the experiment, Manakamana-4 was found super variety in terms of grain yield (4561 kg/ha), leaf senescence (1) and leaf roll (1). Statistically, plant height, ear height, flowering days and leaf senescence due to genotypes were found significantly different. Total eight genotypes were selected for second year's drought tolerance genotypes selection experiment and were planted in three replications. Out of the eight genotypes included in the experiment, Upahar (6897 kg/ha), TLBRSO7F16 (6216 kg/ha) and BLSBSO7F12 (6215 kg/ha) were found superior in terms of grain yield.Int J Appl Sci Biotechnol, Vol 3(3): 387-391

Ear Height

The plant height and the height of the main ear were studied over two years in twelve single cross maize hybrids sown at three different plant densities (45, 65 and 85 thousand plants/ha) at five locations in Hungary (Keszthely, Gönc, Gyöngyös, Sopronhorpács, Martonvásár). The results revealed that plant height and the height of the main ear are important variety traits and are in close correlation with each other. It was found that the hybrids grew the tallest when the genetic distance between the parental components was greatest (Mv 4, Mv 5). The height of the main ear was also the greatest in these hybrids, and the degree of heterosis was highest (193% for plant height, 194% for the height of the main ear). The shortest hybrids were those developed between related lines (Mv 7, Mv 11). In this case the heterosis effect was the lowest for both plant height (128%) and the height of the main ear (144%). The ratio of the height of the main ear to the plant height was stable, showing little variation between the hybrids (37–44%). As maize is of tropical origin it grows best in a humid, warm, sunny climate. Among the locations tested, the Keszthely site gave the best approximation to these conditions, and it was here that the maize grew tallest. The dry, warm weather in Gyöngyös stunted the development of the plants, which were the shortest at this location. Plant density had an influence on the plant size. The plants were shortest when sown at a plant density of 45,000 plants/ha, and the main ears were situated the lowest in this case. At all the locations the plant and main ear height rose when the plant density was increased to 65,000 plants/ha. At two sites (Gönc and Sopronhorpács) the plants attained their maximum height at the greatest plant density (85,000 plants/ha). In Keszthely there was no significant difference between these two characters at plant densities of 65 and 85 thousand plants/ha, while in Gyöngyös and Martonvásár the greatest plant density led to a decrease in the plant and main ear height. The year had a considerable effect on the characters tested.

Background: Bio-fortification, the process of integrating nutrients into food crops, provides a sustainable and economic way of increasing the density of micronutrients in important staple crops. Agronomic bio-fortification is the easiest, practicable and fastest way for bio-fortification of pulse grains with Fe, Zn, or other desirable micronutrients. Increasing micronutrient rich foods and improving dietary diversity will substantially reduce micronutrient disorders.Methods: A field experiment was conducted during the post rainy seasons of 2015, 2016 and 2017 at Zonal Agricultural Research Station, Kalaburagi, University of Agricultural Sciences, Raichur (Karnataka) to know the effect of soil and foliar fertilization of Zn and Fe on chickpea genotypes. Two genotypes (Annigeri 1 and JG 11) and six fertilization treatments (Control, 0.5% Zn, 0.1% Fe, Zn + Fe, seed treatment with 2 g Zn kg-1 seeds and soil application of Zn) were tested in medium black soils in split plot design with three replications.Result: The pooled data of three seasons indicated that the genotype JG 11, performed better than Annigeri 1 in terms of seed yield (1309 kgha-1), net returns (₹ 31634ha-1) and B: C ratio (2.52). On biofortification of Zn and Fe, foliar fertilization of Zn @ 0.5% + Fe @ 0.1% at flowering stage recorded significantly higher grain yield (1321 kgha-1), net returns (₹ 31179ha-1) and B: C ratio (2.44) over rest of the treatments. Further, foliar fertilization of Zn + Fe had significant influence on nutrient concentration (Zn and Fe) in chickpea grains. Thus, it could be concluded that combined biofortification of Zn + Fe to chickpea crop could be the viable agronomic intervention for getting higher productivity and nutritional security.

Two pots experiments were conducted at the Experimental Farm of El-Qassasin Horticultural Research Station, Agricultural Research Center, Ismailia Governorate, Egypt, during two successive seasons of 2016/2017 – 2017/2018, to investigate the effect of potassium silicate at (0, 4, 6, and 8 cm3/l) as a foliar spray under different levels of water salinity (tap water, 1000, 2000 and 3000 ppm) on Calendula officinalis L. plant. The experiment was performed in complete randomized block design as factorial experiment with 3 replicates. The obtained results cleared that using salinity levels decreased growth parameters (plant height, number of branches/plant, fresh and dry weights of herb/plant), flowering parameters (flower diameter, number of flowers/plant, fresh and dry weight of flowers (g/plant) during eight cuts and fresh and dry weight of flowers (g/plant/season)) and chemical constituents (chlorophyll a, chlorophyll b, carbohydrate and carotenoid contents) compared to control. Moreover, the highest values in these parameters were registered by potassium silicate at 8 cm3/l concentration. Proline content increased in leaves with using saline water at 3000 ppm + potassium silicate at 8 cm3/l. Generally, it could be concluded that potassium silicate at 8 cm3/l, showed a uniform impact in alleviating inhibition of Calendula officinallis L. plant growth and productivity under moderate salinity stress condition.

The genetic parameters, characters association and path coefficient analysis between yield and yield components of 32 exotic and local hybrid maize genotypes were studied at Plant Breeding division, Regional Agricultural Research Station (RARS), Bangladesh Agricultural Research Institute (BARI), Rahmatpur, Barisahl during rabi 2015 to 2016, following Alpha Lattice Design with three replications. All the characters showed significant differences among the genotypes except cob length indicating their wide genetic variation. The highest genotypic co-efficient of variation (11.48) observed in yield and lowest (1.72) was found in days to maturity. All of the characters exhibited moderate to high heritability in broad sense (h2b) coupled with a wide range of genetic advance and genetic advance in percentage of mean. Heritability ranged from 19.21 to 86.79 for cob length and thousand seed weight, respectively. Yield had a significant positive correlation with cob length, cob diameter, number of seeds per cob and number of rows per cob. Days to tasseling and number of seeds per cob make highest positive contribution toward yield. While, days to silking and ear height had highest negative direct effect on yield. The results indicated that ear height, number of rows per cob, thousand seeds weight and number of seeds per cob could be considered as selection criteria in maize breeding program. Asian J. Med.
