Effects of on-farm composted seed spices residues on coriander, nutritional parameters and seasonal carbon offset by the crop and soil

Not AvailableField experiments were carried out with seven treatments from three types (coriander, fennel and mixture of these two and others) of vermi-composts (vc) and its two doses (5 and 10t) of vc were compared with control taking coriander (Ajmer coriander-1) as a test crop for three years. First year on lower fertile soil and last two years on medium fertile soil belongs to Subgroup Typic Haplustepts and sandy loam in texture. Results revealed that plant height and primary branches were only higher with 10t vermi-compost of mixed residue (vc-mix). Secondary branches and yield parameters were higher with10t vc of each types as well as 5t of mixed vc. Seed yield of last two years was remarkably higher with each type of 10t vc and 5t of mixed. Per cent yield increased with 10t and 5t mixed vc was 48.7 and 36.4, respectively, whereas 5t each of coriander and fennel vc gave 15.4% higher yield on medium fertile soil. In contrast to it, yield was only 2-5% higher on lower fertile soil with these vermi-composts over the control. Uptake of nutrients by coriander was more with 10t vc over 5t and control. Availability of N and K in soil enhanced with 10t vc, however P and Zn were at par with either level and types of vc, while more over control. Availability of Cu, Fe and Mn was improved with 10t either types of vc or 5t mixed vc. Biological carbon sequestration was higher with each level and types of vc over control, whereas soil organic carbon (SOC) was higher only with 10t vc. Net biological and soil carbon enhanced by vc was ranged from 0.34 to 0.41 and 0.27 to 1.38t ha–1, whereas total offset ranged from 0.61 to 1.79t ha–1. Irrespective of treatments, all the soil and plant parameters were more with mixed vc followed by coriander vc except K availability in soil which was more with fennel vc. Based on the above findings it can be concluded that coriander responded well to vc only on medium soil fertility.Not Availabl

Salinity tolerance of coriander, fennel and fenugreek seed spices under semi-arid conditions of northern India

The present study comprises of two experiments, first conducted in the field while the second in pot house. The field study was conducted on calcareous sandy loam soils of semi-arid regions irrigating crops with water of low salinity EC 4.6 dS m-1, high salinity 8.7 dS m-1, and alternate use of low and high salinity and observed the effect on growth, development and yield of coriander (Coriandrum sativum L.), fennel (Foeniculum vulgare Mill.) and fenugreek (Trigonella foenum-graecum L.). Among three modes of saline water irrigation, continuous low salinity water irrigation resulted in maximum growth and yield of all the three seed spice crops. It was followed by alternate use of irrigation where low and high salinity water irrigations were practiced. The maximum reduction in growth and yield was recorded in continuous use of high saline water irrigation. Among crops, fennel was the most tolerant followed by coriander and least tolerance was observed in fenugreek. Decrease in yield of coriander and fennel from low salinity to alternate irrigations with low and high salinity water was 6 and 27%, and 4 and 19%, respectively. In pot study, 12 promising varieties of each of coriander and fennel were evaluated for their tolerance to salinity of irrigation water ranging from 0.6 control to 3, 6, 9 and 12 dS m-1. Relative yield reduction in each variety of two crops in response to salinity levels was worked out using piecewise linear response [Salt model] fitted to yield in response to salinity. The decrease in yield ranged from 4 to 63% among different varieties of two crops. Coriander variety RCR-446 and GCR-2 were found to be most tolerant while leafy/vegetable type variety as Pant Haritma and seed type as Sadhna and Swathi were least tolerant to salinity. In case of fennel, RF-178, RF-35,GF-1 and GF-2 were most tolerant to salinity of irrigation wate

Not AvailableA field experiment was conducted at Sardarkrushinagar (Gujarat) during 2006-07 and 2007-08 to study response of nitrogen, phosphorus and bio-fertilizers on fenugreek with 16 treatment combinations in factorial RBD with three replications. The soil of the experimental field was low in organic carbon, available nitrogen, medium in phosphorus and good in respect to available potassium. Application of 20 kg N and 40 kg P2O5 /ha gave significantly higher plant height at all the growth stages, and seed, straw and biological yields as well as protein content in seed and straw over 10 kg N and 20 kg P2O5 / ha, respectively. Combined inoculation of seed with Rhizobium and PSB and their sole application significantly gave higher plant height over control at all the growth stages but significantly the highest seed, straw and biological yield as well as protein content in seed and straw was recorded with combined inoculation of seed with Rhizobium and PSB, which was higher over their individual application and control. Sole application of both Rhizobium and PSB was found at par in respect to seed, straw and biological yield. Harvest index was not significantly influenced with N, P and bio-fertilizer levels.Not Availabl

Not AvailableA field experiment carried out with organic manures and mineral fertilizers along with absolute control. There were 12 treatments comprising 10t ha-1 sheep manure, 4t ha-1 vermi-compost, recommended doses of fertilizers (90:40:30 kg ha-1 of N:P:K) alone or in combination with Azotobacter and PSB inoculants. Results revealed that biological sequestration of carbon (C) of fennel was higher with 10 t ha-1 sheep manure and seeds inoculated with PSB over the other treatments and was least in control. However, C accumulation in various parts of crop was more in stover (990.7 kg ha-1) followed by seed (699.6 kg ha-1) and roots (507.1 kg ha-1). Similarly, highest CO2 offset can be achieved by using 10 t ha-1 sheep manure along with PSB in a season (10.03 t ha-1) or per day (62.7 kg ha-1 day-1) basis. Among the manures, C foot print was also higher with 10 t sheep manure along with PSB inoculants thereby net balance of CO2 offsets was higher with vermicompost (4t ha-1) than sheep manure. The net balance of CO2 offset was second highest with PSB and least with control. The pool of soil organic carbon in rhizospheric soil was higher with vermi-compost followed by recommended doses of fertilizers and sheep manure. Therefore, it can be assumed that highest CO2 offset can be credited by fennel with vermi-compost. However, highest growth, yield and ‘C’ sequestration can be achieved by sheep manure along with bio-fertilizers.Not Availabl
