Experimental results indicated that the irrigation schedules at one day after disappearance of ponded water (DPW) recorded the highest grain yield of 3.07 t ha-1 which was at par with irrigation schedule at 2-days after DPW. Both the irrigation schedules were significantly superior over 3-days after DPW. The date of transplanting on 15th January produced highest grain yield (3.11t ha-1) which was significantly superior to other transplanting date on 30th January and 15th February. Highest water use efficiency was observed with irrigation schedule at 3-days after DPW (43.7 kg ha-cm-1) and transplanting on 15th January(43.2 kgha-cm-1). The treatment that received irrigation schedule at 1-day after DPW regis...

Similar trend was also observed for total nutrient uptake. Thus, it may be concluded that application of S @-1 30 or 45 kg ha in the form of gypsum not only increases the bulb yield but also higher uptake of nutrients in onion.

The experiment was conducted in randomized block design with three replications. The treatment consisted of N-P 2 O 5 -K 2 O 60-60-60, 80-60-80 and 100-60-100 kg/ha, the above treatments in combination with FYM 10 t/ha, FYM @ 25 t/ha and control. The results revealed that application of FYM @ 25 t/ha recorded longer pseudostem, higher canopy spread, pseudostem diameter and no. of leaflets per plant. However, yield attributes and corm yield were found significantly higher with the application of N-P 2 O 5 -K 2 O 100-60-100 kg/ha along with FYM 10 t/ha. The nitrogen and potassium uptake was highest in the treatment FYM 10 t/ha along with 100-60-100 NPK kg/ha whereas maximum phosphorus uptake was noticed in the treatment FYM 25 t/ha. The post-harvest soil nutrient status revealed that maximum soil nitrogen and phosphorus was available in FYM 10 t/ha + N-P 2 O 5 -K 2 O 100-60-100 kg/ha and potassium was in N-P 2 O 5 -K 2 O 100-60-100 kg/ha.

The experiment was conducted at the Regional Centre of Central Tuber Crops Research Institute, Bhubaneswar using randomized block design (RBD) with three replications. The experiment comprised of eight treatments involving organic and inorganic fertilizers. Highest leaf area per plant was recorded with the application of FYM 25 t ha-1 and the application of FYM 10 t ha-1 with NPK@ 100- 60-100 kg ha-1. These treatments also resulted in higher light interception and offered lower soil resistance. The application of FYM 10 t ha-1 + NPK@ 100-60-100 kg ha-1 and FYM 25 t ha-1 has produced 105.7% and 97.1% higher corm yield respectively, over control. These treatments maintained higher soil enzyme activities despite poor post harvest soil nutrient status. In alfisols, medium durati...

People during off-season collect the tubers from nearby community lands, mango orchards, forests etc. The wild type of elephant foot yam is having itching property, and hence majority of the people do not consume the tubers. Regional Centre of Central Tuber Crops Research Institute, Bhubaneswar is popularizing Gajendra a non acrid variety throughout Orissa. The yield potential of Gajendra is very high. It yields about 3-4 kg/plant in well managed fields. The average multiplication rate is 7-8 times. It is rich in calcium, phosphorus and other minerals and vitamins.

But, this group of plants are most vulnerable to various pest and diseases. Most of the vegetables are annuals and restricted to location specific environments. Their growth and yield of economic products are drastically reduced under a variety of abiotic stresses. A number of conventional breeding methods are available for genetic improvement of vegetable crops. But, selection of desirable plants in the breeding programme often becomes misleading due to inadequate biotic and abiotic threshold conditions and other environmental factors. Recent advances in development of molecular markers have made it possible for reliable selection and to speed up the breeding cycle in vegetable crops. Therefore, in the present pursuit, the authors presented a detailed review of the role of molecular markers to assist breeding programme of important vegetable crops.

Nicolson]. Higher average monthly maximum temperature was noticed during early crop growth period (vegetative phase) in 2017 compared to 2016. The mean minimum temperature was higher during the cropping period of 2017 compared to 2016. During 2017, Celosia argentea was observed more number and grown more vigourously compared to 2016. The weed biomass was higher during the year 2017 compared to 2016 in all weed management treatments. Higher average monthly maximum and minimum temperatures during early crop growth period (vegetative phase) favoured for more number of weeds to grow vigourously during 2017. The effect of weather was noticed more in pre (1 DAP) and post emergence (45 DAP) herbicide application treatments and weedy check. During 2016 recorded higher corm yield than 2017 irrespective of weed management practices. The weedy check treatment resulted in lower corm yield in 2017 than 2016. It can be concluded that higher rainfall and average monthly maximum temperature during crop growing period led to lower herbicide efficacy or weed management efficiency under high rainfall sub-humid zone.

Nicolson] competes with weeds throughout its growing period owing to its canopy orientation and wider spacing. Manual weeding is the most popular weed control method adopted in elephant foot yam irrespective of drudgery and labourious. A field experiment was conducted for two consecutive years (2016 and 2017

While the adsorption isotherm experiments were carried out in 0.5 M NaCl only, pH variation or batch titration experiments were carried out in 0.5 M NaCl, 0.01 M NaCl, and 0.01 M KNO 3 solutions. The complex nature of adsorption isotherms at constant pH values indicates that adsorption of all the cations is non-Langmuirian (Freundlich) and takes place on the highly heterogeneous oxide surface with different binding energies. The proton stoichiometry derived from isotherms at two close pH values varies between 0.3 and 0.8. The variation of fractional adsorption with pH indicates that the background electrolyte solution influences the adsorption of cations through either metal-like or ligand-like complexes with Cl − , the former showing a low adsorption tendency. The proton stoichiometry values derived from the Kurbatov-type plot varies not only with the electrolyte solution but also with the adsorbate/adsorbent ratio. The variation of fractional adsorption with pH can be modeled either with the formation of the SOM + type or with a combination of SOM + and SOMOH type complexes, depending upon the cation and electrolyte medium. The equilibrium constants obtained from Kurbatov-type plots are found to be most suitable in these model calculations. Adsorption calculated on the basis of ternary surface metal-chlorocomplex formation exhibits very low values.
