“…Among cultivars, a non Bt cultivar (F 1861) took more days (163-178 days) for physiological maturity, while a Bt hybrid (RCH 650 BGII) took lesser duration (151-162 days) to achieve same stage. Early appearance of different growth stages such as first bud, first flower, first boll split and maturity in Bt cultivars over non Bt cultivars has been reported by Thakur et al (2017). Crop experienced extended duration for all the pheno-phases, possibly because of prevailing lower temperature and reduced sunshine hours during 2015 at Faridkot in comparison to other seasons.…”

“…Thus, it can be concluded that early stages were more efficient in utilization of thermal units on per day basis under all the sowing conditions. Due to the inherent ability of Bt cultivars for earlier completion of pheno-phases, PTI for Bt cultivars was better (14.79-16.05°C) than non Bt cultivars (14.18-15.76°C) in accordance with Thakur et al (2017). When mean PTI was compared for different growing seasons, a warmer crop season (Faridkot 2016) consumed more PTI for all the pheno-phases.…”

“…Therefore, the selection of specific cultivar for different sowing windows is another important factor. Bt cotton cultivars require lesser time for maturity having better source-sink ratio, heat use efficiency and hence, lead to higher seed cotton yield (SCY) over non Bt cultivars (Nawalkar et al, 2015;Thakur et al, 2017). In cotton, studies on comparative evaluation of the temperature based thermal units on Bt and non Bt cotton are limited.…”

To understand the impact of weather variability on phenological development and cotton yield efficiency, a field experiment was conducted during kharif 2015, 2016 and 2017, comprising three sowing dates (April 20, May 10 and May 30) in main plots and four diverse cotton cultivars [two Bt hybrids (NCS 855 BGII and RCH 650 BGII) and two non Bt genotypes (F 2228 and F 1861)] in sub plots of the split plot design with three replications. Results indicated that April sown crop acquired more growing degree days (2548-2664°C day), better heat use efficiency (1.09-1.15 kg ha -1 °C day -1 ), and the pheno-thermal index (15.04-15.95°C) having significantly higher above ground biomass (7308-7985 kg ha -1 ) as well as seed cotton yield (2887-3054 kg ha -1 ) as compared to late sowing. Due to earlier completion of phenological duration, the Bt hybrids (NCS 855 BGII and RCH 650 BGII) exhibited superiority in thermal units conversion and economic yield over both non Bt cultivars. Thus, for effective utilization of the available thermal resources and to mitigate the adverse effects of harsh weather conditions on cotton productivity, the sowing of cotton should be done in April month in southwestern Punjab.

TiO 2 or Ag nanoparticles incorporated into polylactic acid (PLA) matrix as a packaging system were studied for Yunnan cottage cheese stored at 5 ± 1 °C for 25 days, and the results revealed that the studied packaging system was helpful in maintaining the quality of cheese and shelf life extension to 25 days [8] .

In this work, the growth of enviro-friendly and biodegradable α-Fe2O3/C20H38O11 nanocomposite is reported by means of a real time application to prolong the storage life of Tomato (Solanum Lycopersicum). A low temperature technique is used to prepare the α-Fe2O3 nanoparticles to obtain a crystalline nanopowder. XRD confirms the phase formation and crystalline nature of α-Fe2O3 nanoparticles. The surface morphology and elemental analysis of α-Fe2O3/C20H38O11 nanocomposite is conducted by SEM and EDX. Nanocomposite exhibits excellent antimicrobial activity against Klebsiella pneumoniae and Staphylococcus aureus bacteria. Tomato fruit samples are coated with two different concentrations of α-Fe2O3/C20H38O11 nanocomposite with 5% UC1A, UC2A and 3% UC1B, UC2B; and uncoated samples UC1, UC2 are stored at room temperature (25 ± 2 °C) and refrigerator temperature (4 °C) respectively for ascorbic acid (vitamin C) analysis on days 0, 4, 8, 12 and 16. Our study revealed that a 3% concentration of α-Fe2O3/C20H38O11 nanocomposite material is quite potent in maintaining quality aspects of the tomato fruit with no decline in vitamin C under refrigerated conditions up to the 16th day. FTIR analysis of all samples was done to determine the functional groups present in tomato samples after storage. Atomic absorption spectrometer (AAS) was used to analyse the content of Fe in tomato samples.

Dry matter partitioning in Bt and non Bt cotton (Gossypium hirsutum) cultivars under different sowing environments of Punjab

A field experiment was conducted at Punjab Agricultural University (PAU), Regional Research Station (RRS), Faridkot and Bathinda during rainy (kharif) season 2017 to evaluate the performance of Bt and non Bt cotton (Gossypium hirsutum L.) cultivars under different sowing environments. The experiment was laid out in split plot design with 3 sowing dates (April 20, May 10 and May 30) in main plots and 4 American cotton cultivars [2 Bt cultivars (NCS 855 BGII and RCH 650 BGII) and 2 non Bt cultivars (F 2228 and F 1861)] in sub-plots. Results of the pooled data indicated that early sown (April 20) crop accumulated more dry matter production, higher crop growth rate (CGR) as well as relative growth rate (RGR) followed by crop sown on May 10 and May 30. Maximum CGR (14.35–15.48 g/m2/day) was obtained during 90–120 DAS (days after sowing) while RGR was highest during 60–90 DAS. Among tested cultivars, F 1861 exhibited better CGR and RGR values and hence, accumulated higher dry matter (1303.0 g/m2) followed by F 2228 (1276.9 g/m2), NCS 855 BGII (1261.1 g/m2) and RCH 650 BGII (1206.7 g/m2). Dry matter accumulation in fruiting bodies has started around 90 DAS and accounted for 30–35% of total above ground biomass. Bt cultivar NCS 855 BGII, accumulated higher dry matter in fruiting bodies (458.1 g/m2), though at par with RCH 650 BGII (432.2 g/m2) but, significantly higher than F 1861 (403.3 g/m2) and F 2228 (401.9 g/m2). Dry matter accumulation towards fruiting bodies in Bt cultivars was ~9% higher than non Bt cultivars which may be prime reason for better yield performance of Bt cotton.
