Tillage Practices

A field experiment was performed to evaluate the effects of tillage systems and fertilizer management on the growth and nutrient uptake in soybean. The plant height, fresh weight and dry weight of conventional tillage (CT) were much higher those observed for no-tillage (NT). The highest plant height (128.47 cm) was observed in CT with chemical fertilizer. The plant nitrate concentration was higher (2.29%) in NT with green manure than chemical fertilization. However, nitrogen increased steadily in all treatments, and the highest quantity of total nitrogen (476.7 Kg/ha) was observed in NT with green manure. The NO3-N content in the soil decreased gradually just after the vegetative stage. Tillage practices and additional fertilizer application was less effective on the uptake of N, P and K in soybean seeds as compared to NT with green manure. The results postulated that NT strategies with fertilizers might influence the growth characteristics and mineral uptake in soybean.

A research to study the effects of Zeolite and nitrogen fertilizer application on vegetative growth of maize crop in coastal sandy soil was conducted on the research field of Agriculture Faculty, Muhammadiyah University of Yogyakarta at Tamantirto, Bantul District of Yogyakarta during October until February, 2003. This research was aimed on the study of Zeolite application in order to enhance the nitrogen uptake in the coastal sandy soil, and its effects on vegetative growth of CP I variety of maize. The pot experiment was arranged in 7 x 3 factorial completely randomized design, with 4 replications. The first factor was Zeolite dosage consisted of 7 levels, i.e:  0, 3, 4, 5, 6, 7, and 8 %; and the second one was 3 levels nitrogen fertilizer dosage which consisted of: 75, 110, and 145 kg/ ha. The nitrogen fertilizer was applied on the medium mixed with Zeolite granules. Observations on plant height, stem diemeter, leaves number, plant fresh and dry weight were done during the vegetative growth of maize. The results showed that Zeolite application significantly enhanced the vegetative growth of CPI maize. The 5,2  - 5,6  % Zeolite was optimum to gave the maximum growth of maize crop. Nitrogen fertilizer application was also significantly increased the plant height and biomass weight, and the 145 kg/ha was the optimum dosage. There was no interaction between Zeolite and nitrogen fertilizer application in order to affected the maize growth.

Abstract. Soil compaction is common problem of mineral soils under conventional tillage practices. Organic matter addition is an efficient way of reducing the effects of field traffic in soil compaction. The aim of this study was to investigate the effects of number of tractor passes (1, 3 and 5) on depth dependent (0–10 and 10–20 cm) penetration resistance, bulk density and porosity of a clay textured soil (Typic Xerofluvent) under organic vegetable cultivation practiced in 2010–2013 growing seasons treated with farmyard manure (35 t FYM ha−1), green manure (GM) (common vetch, Vicia sativa L.) and conventional tillage (C). The number of tractor passes resulted in increases in bulk density and penetration resistance (C > GM > FYM) whereas the volume of total and macro pores decreased. The maximum penetration resistance (3.60 MPa) was recorded in C treatment with 5 passes in 0–10 cm depth whereas the minimum (1.64 MPa) was observed for FYM treatment with 1 pass in 10–20 cm depth. The highest bulk density was determined as 1.61 g cm−3 for C treatment with 5 passes in 10–20 cm depth, the smallest value was 1.25 g cm−3 in the FYM treatment with only 1 pass in 0–10 cm depth. The highest total and macro pores volume were determined as 0.53 and 0.16 cm3 cm−3, respectively, in 0–10 cm depth of FYM treatment with 1 pass. The volume of micro pores (0.38 cm3 cm−3) was higher in 0–10 cm depth of FYM treatment with 3 passes. It can be concluded that organic pre-composted organic amendment rather than green manure was likely to be more efficient in chasing compaction problem in soils.

Synthetic Nitrogen Fertilizer

This intervention examines commodity grain and oilseed farmers’ over reliance on synthetic nitrogen fertilizer in North America. Most grain and oilseed farmers apply synthetic nitrogen fertilizer at rates higher than necessary in order to ensure maximum yields. At the same time, high fertilizer application rates lead to increased farm input expenses and generate significant amounts of water pollution and excessive greenhouse gas emissions. A number of low-cost alternative approaches have been developed which can significantly reduce or eliminate the need for synthetic nitrogen fertilizer while maintaining farm profitability. But such practices have only seen limited adoption by Canadian and US farmers. This is despite significant production cost savings and environmental benefits. A number technological and institutional factors work in combination to lock farmers into production models requiring large amounts of synthetic nitrogen fertilizer. They include crop varieties bred to thrive in artificially high nitrogen soil conditions, conventional tillage practices, restrictive financial arrangements, largely unenforced water quality laws, and non-diverse marketing outlets. These technological and institutional lock-ins are significant barriers to the adoption of alternative crop production practices that are less reliant upon synthetic nitrogen fertilizer.

Abstract. Soil compaction is a common problem of mineral soils under conventional tillage practices. Organic matter addition is an efficient way of reducing the effects of field traffic in soil compaction. The aim of this study was to investigate the effects of number of tractor passes (one, three, and five) on depth-dependent (0–10 and 10–20 cm) penetration resistance, bulk density, and porosity of clay-textured soil (Typic Xerofluvent) under organic vegetable cultivation practices in the 2010–2013 growing seasons. Fields were treated with farmyard manure (FYM, 35 t ha−1), green manure (GM; common vetch, Vicia sativa L.), and conventional tillage (CT). The number of tractor passes resulted in increases in bulk density and penetration resistance (CT > GM > FYM), whereas the volume of total and macropores decreased. The maximum penetration resistance (3.60 MPa) was recorded in the CT treatment with five passes at 0–10 cm depth, whereas the minimum (1.64 MPa) was observed for the FYM treatment with one pass at 10–20 cm depth. The highest bulk density was determined as 1.61 g cm−3 for the CT treatment with five passes at 10–20 cm depth; the smallest value was 1.25 g cm−3 in the FYM treatment with only one pass at 0–10 cm depth. The highest total and macropore volumes were determined as 0.53 and 0.16 cm3 cm−3 respectively at 0–10 cm depth for the FYM treatment with one pass. The volume of micropores (0.38 cm3 cm−3) was higher at 0–10 cm depth for the FYM treatment with three passes. It can be concluded that organic pre-composted organic amendment rather than green manure is likely to be more efficient in mitigating compaction problems in soil.

Currently, a real challenge for the workers in the agricultural research field is to stop or reduce the use of expensive agrochemicals/ chemical fertilizers which are hazardous to the environment as well as human health. Present study was aimed to improve the growth and obtain optimum yield of Vigna crop with eco-friendly, non-toxic way and to reduce the use of agrochemical/chemical fertilizer application in agricultural activities. A pot experiment was conducted to study the effect of chemical fertilizer (DAP) and biofertilizer ( Rhizobium strain) separately and in combination on seed germination and seedling growth (at 30 days) based on morphological parameters such as seedling length (cm), fresh weight (g), dry weight (g) and leaf area (cm)2 of Vigna radiata (L.) Wilczek. After one month (30 Days) observations, it was found that seedling length, fresh and dry weights and leaf area were maximum in T4 and minimum in T15, T7 and T8 favored improved seedling length and leaf area whereas T7, T8, and T9 favored improved fresh and dry weights as compared to control.

A pots experiment was conducted at the Department of Biology/College of Education for Girls/University of Anbar during Autumn season of 2018-2019 to study the effect of the salinity irrigation water and spray by humic acid in some of morphological, physiological, growth and yield traits of wheat cv. IPa. The experiment was randomized complete block design (RCBD) with three replications. The first factor was assigned for irrigation by saline water at four level (S0, S1, S2 and S3), while the second factor was the foliar spraying of humic acid in three level (0.0, 1.0 and 1.5 g l-1). The results showed that there was significant reduction in plant height, vegetative dry weight, biological yield and chlorophyll leaves content when the plants were irrigated by saline water approached to 41.09 cm, 0.747 g, 0.849 g plant-1 and 38.67 SPAD, respectively at salinity level of 8.3 ds m-1 compared with the plants which irrigated by fresh water. The total carbohydrates were significantly decreased at the treatment of 8.3 ds m-1 reached 18.71 mg g-1. Spray levels humic acid achieved a significant increase in plant height, dry weight of the vegetative part, biological yield and chlorophyll leaves content sprayed at 1.0 and 1.5 g l-1 compared to no sprayed. Nitrogen concentration was significantly increased, while both phosphorus and potassium were decreased in the vegetative parts of wheat as the salinity of irrigation water increased. However, the increase of humic acid levels led to significant increasing in nitrogen, phosphorus and potassium concentration.

Nicotiana alata Link and Otto. was transformed via Agrobacterium tumefaciens encoding a senescence-specific promoter SAG12 cloned from Arabidopsis thaliana fused to a Agrobacterium tumefaciens gene encoding isopentenyl transferase (IPT) that catalyzes cytokinin synthesis. This was considered an autoregulatory senescence-inhibitor system. In 1996, we reported delayed senescence of intact flowers by 2 to 6 d and delayed leaf senescence of transgenic vs. wild-type N. alata. Further evaluations in 1997 revealed several other interesting effects of the SAG12-IPT gene construct. Measurement of chlorophyll content of mature leaves showed higher levels of both chlorophyll a and b in transgenic material under normal fertilization and truncated fertilization regimes. At 4 to 5 months of age transgenic plants expressed differences in plant height, branching, and dry weight. Plant height was reduced by 3 to 13 cm; branch counts increased 2 to 3 fold; and shoot dry weight increased up to 11 g over wild-type N. alata. These observations indicate the system is not tightly autoregulated and may prove useful to the floriculture industry for producing compact and more floriferous plants.
