Maize Fertilization

Maize (Zea mays. L) is a source of carbohydrates as food, feed ingredients for livestock and industrial raw materials and bioethanol raw materials. To optimize the productivity of local maize, fertilization can be done. The use of organic fertilizers is very good for maintaining soil health, one of them is vermicompost. The application of vermicompost fertilizer is the right solution in this problem because composting of organic waste with the help of earthworms (Lumbricus sp.) contains high nutrients. The needs of adequate nutrient and growing environment will maximize the genetic potential of a variety. This research was conducted with the aim to determine the effect of vermicompost fertilizer on growth and yield of several maize varieties (Zea mays L). This study used a grooved plot design (Strip Plot) with 3 replications. The vertical path consists of 4 doses of fertilizer, namely P0 = 0 ton /ha, P1 = 4.5 tons/ha, P2 = 9 tons/ha, and P3 = 13.5 ton/ha. Horizontal path consists of 4 varieties, namely V1 = Dampit local variety, V2 = Arjuno superior variety, V3 = Karangploso local variety and V4 = Madura local variety (V4). Results of this study shows that fertilizer dose is 13.5 tons/ha (P3) and themaizeDampit localvariety (V1) showed good results on the growth and yield of maize crops. The results of P3V1 in maize plants were 2.66 kg of maize per bed and 1.15 kg of maize per bed. Keywords: Maize, Varieties, Vermicompost.

A glass house study was conducted to evaluate the contribution of indigenous arbuscular mycorrhiza fungi (AMF) in improving maize yield grown on sandy loam of Northern Lombok. The package of organic fertilizers treatments were tested including: without inoculation of mycorrhiza, inoculation mycorrhiza and no added inorganic fertilizers, inoculation of mycorrhiza with cattle manure added, inoculation of mycorrhiza with rock phosphate added and inoculation mycorrhiza with inorganic fertilizers. The treatments were arranged using a Completely Randomized Design with four replications. The results of the study show that the inoculation of AMF significantly increased soil concentration of N, available-P, K and organic-C by 37.39%, 60.79%, 66.66% and 110.15% respectively observed at 60 days after sowing (DAS). The similar trend was also found at 100 DAS, where those nutrients increased by 21.48%, 69%, 43.93% and 37.07%, respectively compared to control. The improving of soil fertility status was also reflected by nutrients uptake (i.e. N, P, K, Ca) as well as growth and yield of maize. N, P, K and Ca uptake increased by 1,608%, 1,121%, 533% and 534%, respectively. Roots and top dry biomass at 60 DAS increased by 718.40% and 337.67%, respectively. The trend increased of the biomass was followed by observation at 100 DAS. Yield components including cobs, grain and weight of 100 grains increased by 313.60%, 411.84% and 137.54%, respectively. In addition, the inoculation of AM with F2 contributed significantly to the spore numbers and root infection.[How to Cite : Astiko W, IR Sastrahidayat, S Djauhari, and A Muhibuddin. 2013.

To reduce the existing yield gap of maize crop between research and farmer’s field, the experiment was carried out during the period from March, 2014 to June, 2014 at the experimental field of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh. The experiments were laid out in RCBD method with three replications and eight treatments including control viz. Treatment0 = control (no fertilizer), Treatment1=recommended dose N250 P50 K100 S25 Zn2 B1 kg ha-1, Treatment 2=American NPK+N250 P50 K100 S25 Zn2 B1, Treatment3=Bio-forge+N250 P50 K100 S25 Zn2 B1 , Treatment4=Wuxal+N250 P50 K100 S25 Zn2 B1, Treatment5=Peak+N250P50K100S25Zn2B1, Treatment6=Root Feed+N250 P50 K100 S25 Zn2 B1 and Treatment7=Nitro Plus+N250 P50 K100 S25 Zn2 B1 and three maize varieties namely Variety1=BARI Hybrid Bhutta-5, Variety2=BARI Hybrid Bhutta-6 and Variety3=BARI Hybrid Bhutta-9. Growth and yield contributing characters mainly plant height, cob length, cob weight, 100-kernel weight and kernel yield of maize crop were significantly influenced by the next generation fertilizers. Bio-forge along with other recommended fertilizers performed the best compared to other treatments of the study in aspect of kernel yield (5.95 t ha1) and statistically similar result showed by Root Feed along with other recommended fertilizers and produced 5.12 t ha1 kernel yield.

Improving drought stress tolerance in maize is essential to increase its production and yield worldwide.  Thus, the present study was conducted to investigate the improvement of drought tolerance in maize (Zea mays L.) by exogenous application of proline (25 and 50mM) on two maize varieties. Maize plants were subjected to drought stress at various phases of plant growth under pot culture conditions and proline was applied as foliar spray. Water deficit stress caused a significant decrease (by approximately 25%) in growth and yield of both maize varieties by decreasing plant height, cob length, dry root weight, grains per cob and 100-grain weight. Water deficit stress also decreased chlorophyll and intercellular proline contents, and antioxidant enzyme activities viz. catalase (CAT), guaiacol peroxidase (POX) and ascorbate peroxidase (APX). Exogenous application of proline (50 mM) was found to be more effective in increasing growth and yield of both varieties. These increases were positively associated with increased levels (by at least 15%) of chlorophyll and intracellular proline, and enhanced activities of CAT, POX and APX enzymes in both varieties. Interaction effects of exogenous proline and water deficit stress were significant in aspects of higher growth and yields and enhanced levels of chlorophyll, intracellular proline and antioxidant enzyme activities. Therefore, it is concluded that foliar application of proline improves drought tolerance by modulating chlorophyll and intracellular proline contents, and antioxidant enzyme activities.

Microsatellite or simple sequence repeat (SSR) markers have wide applicability for genetic analysis in crop plant improvement strategies. Marker-assisted selection is an important tool for plant breeders to increase the efficiency of a breeding process, especially for multigenic traits, highly influenced by the environment. In this paper, the relationships between SSR markers and 26 quantitative traits of hybrid maize varieties (Zea mays L.) were analyzed. Association analyses were performed based on 30 SSR primers in a set of thirteen hybrid maize varieties. A total of 112 SSR markers were detected in these genotypes. The number of alleles per locus ranged from 1 to 17, with the average number of alleles per locus equal to 3.7. The number of molecular markers associated with observed traits ranged from 1 (for the number of kernels in row, ears weight and fresh weight of one plant) to 14 (for damage of maize caused by P. nubilalis) in 2016 as well as from 1 (for soil plant analysis development—SPAD, the number of grains in ear and fresh weight of one plant) to 12 (for carotenoids content) in 2017. The sum of statistically significant associations between SSR markers and at least one trait was equal to one hundred sixty in 2016 as well as one hundred twenty-five in 2017. Marker trait associations (MTAs) were found on the basis of regression analysis. The proportion of the total phenotypic variances of individual traits explained by the marker ranged from 24.4% to 77.7% in the first year of study and from 24.3% to 77.9% in 2017. Twenty-two SSR markers performed a significant effect on at least one tested trait in both years of experiment. The three markers (phi021/4, phi036/3, and phi061/2) can be a good tool in marker-assisted selection because they allow simultaneous selection for multiple traits in both years of study, such as the number of kernels in row and the number of grains in ear (phi021/4), the number of plant after germination, the number of plants before harvest, and the number of ears (phi036/3), as well as moisture of grain and length of ears (phi061/2).
