Sowing Period

In India agriculture and its practices plays the vital role, since more number of people are employed in that process. The agricultural process goes on with the sowing, maintenance and yield. The yield of the crop purely depends on the season, maintenance and the nutrient content available in the soil. Soil nutrient analysis has been made before sowing period with the help of soil testing laboratory, based on the laboratory results and the selected crops. End of the analysis process the fertilizer suggestion would be given to the farmer. In the existing system the analysis process is done manually and farmers would be given direct suggestion about the fertilizer. Since the process is repetitive it consumes more time and there may be chance of human error which may majorly affect the yield. The main aim of the proposed work is to design an Automated Fertilizer Suggestion (AFS) application to give effective suggestions to farmers about the fertilizers with respect to crops based on the soil test results. Our proposed application reduces the time, controls the human errors, avoids the over dumping of fertilizer in the soil and improves the yield.

An investigations on nutrient analysis of soil under the different agro-climatic zones of Kashmir and Ladakhviz Temperate (Pattan, Baramulla),Sub temperate(Gurez,Bandipora) and Cold Arid(Kargil,Ladakh) was carried out during 2012 and 2013.The studies revealed that soils were alkaline in their reaction with slightly higher pH (8.2) recorded at Kargil followed by Pattan (7.9) and Gurez (7.6). Electrical conductivity was highest (0.23dSm-1) at Pattan and least at Kargil (0.08dSm-1). Pattan soils were richer in organic carbon with an average value of 1.02%. Varied results were obtained with respect to available soil nitrogen, the highest being recorded at Pattan with an average value of 372.8 kg ha-1 Gurez recorded251.5 kg ha-1 and Kargil 184.9 kg ha-1. Pattan recorded maximum (22.45 kg ha-1) soil available phosphorus while the sulphur was recorded highest (53.40 kg ha-1) at Kargil.Among the three agro-climatic zones, (187.30 kg ha-1), exchangeable calcium (17.56 centimole) and exchangeable magnesium (5.54 centimole).

Strawberry Cultivars

Cultivar may cause variation in arbuscular mycorrhizal fungi (AMF) colonization levels leading to differences in shoot growth and runner formation, and in pathogen control in strawberries. However, a clear consensus has not been reached regarding the degree to which cultivar affects the formation of the symbiosis or its functioning. The study was conducted on four commercial strawberry farms in Minnesota and Wisconsin to compare, within a farm, mycorrhizal colonization and plant response among three strawberry cultivars: `Winona', `Anapolis' and `Jewel'. At each farm, two 6 × 6 meter plots of each cultivar were randomly selected. On each of three sampling dates, 4 whole plants and soil samples were collected from these plots in the 2003 field season. Roots were separated from shoots and leaves, and fresh and dry weights were taken. Leaves and soil were dried, weighed, and submitted for nutrient analysis. Soil nutrient analyses include phosphorus (Bray P), potassium, pH, buffer pH and organic matter. Leaf tissue analyses include P, K, Ca, Mg, Na, AL Fe, MN Zn, Cu, B, Pb, Ni, Cr, and Cd. Roots were collected, frozen, and prepared for scoring using methods adapted from Koske and Gemma (1989). Presence of mycorrhizal colonization is being scored using the methods of McGongle et al. (1990). Levels of mycorrhizal colonization among different strawberry cultivars will be compared. We will also use biomass measurements, to determine mycorrhizal effects on plant growth among different cultivars. Soil and leaf analysis data will be used to determine effects of AMF on plant nutrition and compare effects among cultivars.

The influence of regrowth time on the forage quality of prairie grass (Bromus willdenowii Kunth. cv. Matua), perennial ryegrass (Lolium perenne L. cv. Dobson) and tall fescue (Festuca arundinacea Schreb. cv. Dovey) was determined under non-limiting soil nutrient and moisture growth conditions. In a glasshouse, individual plants of each species were arranged in separate mini-swards and were defoliated at 6, 10 and 14 weeks after sowing to a stubble height of 60 mm for perennial ryegrass and tall fescue and 90 mm for prairie grass. Following defoliation at 14 weeks, selected individual plants were cut to the previous stubble height as each new leaf per tiller was fully expanded, to provide leaf material for nutrient analysis, until prairie grass, perennial ryegrass and tall fescue had attained 6–8, 5 and 3 leaves/tiller, respectively. The concentration of leaf phosphorus (P) decreased from 6.6 to 5.9 g/kg dry matter (DM) in prairie grass, increased from 5.9 to 6.9 g/kg DM in perennial ryegrass, and initially increased to 8.8 g/kg DM and then decreased to 8.4 g/kg DM in tall fescue. The mean potassium (K) content in perennial ryegrass was 29.6 g/kg DM and was not significantly affected by duration of regrowth, whereas K content in prairie grass and tall fescue fell from 51.7 to 43.6 g/kg DM and from 55.5 to 47.9 g/kg DM, respectively, after the first leaf per tiller formed. Calcium levels increased with regrowth in all species and at the completion of regrowth were 5.8, 3.8 and 3.4 g/kg DM in prairie grass, perennial ryegrass and tall fescue, respectively. The magnesium (Mg) and sodium (Na) content of perennial ryegrass showed no change throughout the regrowth period and had measured values of 2.5 and 2.8 g/kg DM, respectively. For tall fescue, the concentration of leaf Mg decreased from 0.30 to 0.24 g/kg DM, whereas the Na concentration increased from 1.2 to 2.1 g/kg DM. The Mg content of prairie grass remained constant at 2.0 g/kg DM, whereas the Na content increased from 2.7 to 4.3 (g/kg DM). While the crude protein content of all grasses declined over the regrowth period, values remained over 200 g/kg DM, well above the recommended content for lactating cows. The leaf water-soluble carbohydrate (WSC) of prairie grass and perennial ryegrass increased over the regrowth period from 29.7 to 43.9 g/kg DM and from 25.9 to 72.5 g/kg DM, respectively, whereas tall fescue showed no change at 55.6 g/kg DM. The change in in vitro organic matter digestibility (OMD) with age was 125 and 44 (g/kg DM) for tall fescue and perennial ryegrass, respectively. The OMD of prairie grass decreased following the onset of stem elongation at the 5-leaves/tiller stage of regrowth from 824 to 756 g/kg DM. In this glasshouse study, the pattern of change in K and Ca content was the same as observed in the field but the absolute content, including that of Na, was greatly elevated, particularly in prairie grass. In terms of nutrient content capability, N, P and K were readily taken up by these C3 grasses, while the uptake of Mg and Na appear to reflect genetic differences between species. The differences in forage quality as determined under optimal growth conditions in this study, as compared with field grown forage, are presumed to indicate possible soil nutrient deficiencies in field situations.

Experiments conducted over 5 years evaluated the effect of compost applications on the yield of several vegetable crops grown under organic farming conditions in the tropics. The yield of organically grown lettuce, basil, Filipino spinach (Corchorus olitorius L.), and zucchini after application of 20 MT compost/ha per crop was compared to yields obtained with standard synthetic fertilizer applications (150 kg N/ha per crop), and with a combination of several compost: synthetic fertilizer ratios. Treatments consisted of 10 by 1.30-meter raised beds replicated four times. Data collected included soil nutrient analysis prior to planting and after the last harvest, tissue analysis of macro- and micronutrients, canopy dimensions, and yields. The tissue nutrient levels collected from crops receiving composts alone were at or above those levels recommended to achieve commercially acceptable yields. Yields of plants receiving composts alone were comparable to those obtained by plants receiving synthetic fertilizer applications. However, the greatest yields were obtained with 20 MT·ha–1 of compost plus supplemental synthetic N applications, depending on the length of the harvesting period. After 5 years cumulative yields ranged from 110 to 124 MT·ha–1 for vegetables receiving compost plus supplemental N, compared to 75 for controls, and to about 100 MT·ha–1 for treatments receiving either synthetic N or compost applications alone.
