A field experiment was conducted in split plot design (SPD) with 20 treatment combinations for two years (2007-08 and 2008-09) at NBPGR, New Area Farm, IARI, New Delhi during rabi seasons. Treatments were consist of two planting systems (conventional and FIRB) and 10 fertility treatments, viz. control, RDF, 75% RDF + FYM, 75% RDF + FYM + Zn, 75% RDF + FYM + Biofertilizer (BF), 75% RDF + FYM + BF + Zn, RDF + FYM, RDF + FYM + Zn, RDF + FYM + BF and RDF + FYM + BF + Zn. Results revealed that the root dry weight, root volume, root length and root length density were recorded higher values in FIRB planting system than conventional system at all growth stages during both the years of investigation. Whereas in case of integrated nutrient management, root growth parameters of wheat, viz. root dry weight, root volume, root length and root length density were significantly higher at various observational growth stages when crop was supplied with combined application of RDF or 75% RDF along with FYM, biofertilizer and zinc over the control and treatment RDF only during both years of field study. However, specific root length was significantly lower under treatment receiving RDF or 75% RDF + FYM + BF + Zn as compared to control at 30 and 60 DAS during the years, 2007-08 and 2008-09. In case of wheat yield, 10.8 and 11.3% higher yield were registered with FIRB planting system over conventional system during 2007-08 and 2008-09. However in case of integrated nutrient management, RDF + FYM + BF + Zn treatment produced 50.39 and 52.73 q/ha wheat yield respectively. Source

It is fact that Polymers and their products have changed the face of the world in all the field of the technology. They are the future of the coming up generation of the research of the world. But this is also fact that these synthetic non biodegradable polymers have created a tough situation for the living being for a healthy life. Polyhydroxyalkanoates are polyesters produced by bacteria as intracellular storage materials in response to a variety of nutritional and environmental conditions, such as nitrogen limitation Polyhydroxyalkanoates (PHAs) are gaining increasing attention in the biodegradable polymer market due to their promising properties such as high biodegradability in different environments, not just in composting plants, and processing versatility. Indeed among biopolymers, these biogenic polyesters represent a potential sustainable replacement for fossil fuel-based thermoplastics. Most commercially available PHAs are obtained with pure microbial cultures grown on renewable feedstocks (i.e.glucose) under sterile conditions but recent research studies focus on the use of wastes as growth media.PHA can be extracted from the bacteria cell and then formulated and processed by extrusion for production of rigid and flexible plastic suitable not just for the most assessed medical applications but also considered for applications including packaging, moulded goods, paper coatings, non-oven fabrics, adhesives, films and performance additives. The present paper reviews the PHAs, their main properties, processing aspects, commercially available ones, as well as limitations and related improvements being researched,with specific focus on potential applications of PHAs in packaging. © 2016, Springer Science+Business Media Dordrecht.

A field experiment was conducted during 2005-06 and 2006-07 to evaluate sowing date and nitrogen levels in the vegetable pea. The vegetable pea-wheat-maize crop rotation repeated on the fixed plot for 2 years. The different doses of nitrogen were applied in vegetable pea whose residual effect was studied on second (wheat) and third (maize) crop applying uniform level of fertilizer dose in wheat and maize. The growth characteristics of vegetable pea, ie plant height, nodules/plant, dry weight/plant, fresh weight/plant, dry weight/plant, days to 50% flowering and days of first picking of pods is significantly higher when vegetable pea is sown on 20 October compared with 30 September and 10 October sown. The growth characters of vegetable pea and wheat crop is significantly higher in N80 treatment compared to N60, N 40, N20 and No treatments, respectively. The B:C ratio shows the opposite trend which shows the highest ratio of 1:1.72 sown on 30 September than observed on later dates of sowing. This may be due to the fact that early vegetable fetches more prices in the market. The higher pod yield of vegetable pea was 5.43 tonnes/ha sown on 20 October which was 4.3 and 8% higher than the pod yield obtained in 10 October and 30 September sown, respectively. Significantly higher yield of 5.48 tonnes/ha was recorded at N80 treatment which was 0.8,2.7, 6.5 and 1.5% higher than N60, N40, N 20 and No kg/ha. The yield of wheat crop is maximum, ie 3.66 tonnes/ha in first date of sowing which was 3.0 and 6% higher than second and third date of sowing. The residues of N from N80 treatment plot being at par with N60 and N40 levels producing significantly higher yield of wheat than N20 and No levels. Non-significantly relationship was observed for all nitrogen treatments in maize crop. Source

A field experiment was conducted at Bichpuri (Agra) during rabi season of 2006-07 and 2007-08 to assess the effect of organic and inorganic fertilizers on wheat (Triticum aestivum L.) productivity and soil fertility. The grain and straw yields of wheat increased significantly with increasing levels of NPK fertilizers up to 150% NPK. The average increase in grain and straw yield over the control was 29.7 and 32.3 and 46.2 and 56.4 % with the application of 100 and 150% NPK, respectively. There was a significant increase in uptake of nutrients by wheat crop up to 150% NPK and in Zn uptake up to 100% NPK. Integrated use of fertilizers with S and Zn increased the grain and straw yield by 32.0 and 43.4 and 35.5 and 45.5 % over control, respectively. The highest grain and straw yield was recorded with 100% NPK + 12.5 tonnes FYM/ha with a record of 46.5 and 57.7 % increase over control (28.73 and 39.87q/ha ) while the application of 100% NPK + 7.5 tonnes GLM/ha ( 42.7 and 45.9 %) was on par with 150% NPK. The combined use of 100% NPK + 12.5 tonnes FYM/ha gave the highest net return and benefit:cost ratio. In general, fertilizer treatments including FYM proved superior to no FYM in respect of yield of protein. The maximum uptake of NPK by the crop was noted with 150% NPK which was statistically at par with 100% NPK + 12.5 tonnes FYM/ha and those of S and Zn with 100% NPK + 20 kg S/ha and 100% NPK + 5 kg Zn/ha, respectively. Integrated use of FYM with mineral fertilizers improved the organic carbon status and available N, P, K, S and Zn in soil thereby, sustaining the soil health. The omission of S and Zn in fertilizer schedule caused a depletion in the available S and Zn status of soil. Source

A field experiment was conducted during rabi seasons of 2005-07 at Bichpuri (Agra) to study the response of faba bean to Zn application Application of zinc upto 5 kg ha -1 significantly increased the seed and straw yield of faba bean by 33.7% and 39 8% whereas at higher zinc level (10 kg Zn ha -1) the yields tended to decrease Zinc application increased the uptake of N, P, K, S and Zn in faba bean seed and straw over control. The maximum values of protein content (26.53%) and yield (13 9 q ha -1) in seeds were recorded with 5 kg Zn ha -1 Faba bean crop gave maximum net profit (Rs 128690 ha -1) and B /C ratio (2.34) with 5 kg Zn ha -1 The apparent recovery of zinc was influenced by zinc level with maximum (2 2%) at 5 kg Zn ha -1 The zinc use efficiency decreased with its increasing levels and minimum use efficiency was recorded at 10 kg Zn ha -1 application.
