Castor (Ricinus communis L.) is an important industrial oilseed crop grown worldwide. Wilt caused by Fusarium oxysporum f. sp. ricini is a devastating disease of this crop. The objective of this research was to identify stable sources of wilt resistance among the global castor germplasm collections available in India for use in cultivar improvement. The global collections comprising 1,779 Indian and 190 exotic accessions from 36 countries were screened against wilt in wilt sick plots at two sites in India in preliminary screening. None of the accessions showed high resistance to wilt, 133 accessions comprising 111 Indian and 22 exotic accessions representing 13 countries exhibited resistance. Thirteen of the 133 resistant accessions were tested further for multiple years in wilt sick plots and glasshouse under controlled artificial inoculation at two sites. All the 13 accessions consistently showed wilt resistance in both wilt sick plot and glasshouse at both sites in multiple years. Eleven of these 13 accessions were from India and two were from former USSR. Evaluation for agro-morphological traits identified high seed yielding and early maturing resistant accessions. Diversity analyses precisely revealed diversity among the resistant accessions. These 13 resistant accessions would be great value as donors of resistance. © 2014 Koninklijke Nederlandse Planteziektenkundige Vereniging.

Pestology | Year: 2014
Cauliflower (Brassica oleracea var. botrytis) is major vegetable produced and consumed in India. Over the years, they have been cultivated more intensively. This has resulted in higher rates of pest infestation, especially the diamondback moth (Plutella xylostilla). The findings of a field experiments conducted during 2010 to 2012 revealed that among the four modules tested against major pest of cauliflower, the IPM module-II was found more effective against larval population viz., H. armigera, S. litura and P. xylostella. The higher ICBR was obtained in the IPM module-II (1:10.4) followed by IPM module-Hl (1:9.7). Results show that IPM module-II registered significantly lower larval population (0.34 larvae/plant, 0.23 larvae/plant and 0.54 larvae/plant) respectively of H. armigera, S. litura and P. xylostella. The curd yield of cauliflower was observed in the order of IPM module-II (155.70 q/ha) > IPM module-I (147.98 q/ha) > IPM module-III (139.88 q/ha) and least under control module (87.18 q/ha) in pooled results.

Stability analysis was carried out in eleven genotypes of cowpea over four different environments (two years and two locations) to identify phenotypically stable genotypes for yield and their component traits. Pooled analysis of variance for stability in the performance of different genotypes of cowpea were highly significant for all the characters viz., days to 50% flowering, days to maturity, pods per plant, plant height, seeds per pod and seed yield. The G X E interaction was significant for all the characters except days to 50% flowering and seeds per pod and the significant mean square due to the environment (linear) indicated the existence of the real genotypic differences in characters for regression over the environmental mean. The genotypes namely GC-0525 for earliness, GC-0521, GC-0510 and GC-0119 for plant height, GC-0203, GC-0119, and GC-5 for pods per plant and GC-04 for seed per pod were found stable and they can be directly used for breeding program. For improvement of grain yield, the genotype GC-0121 was most stable and found 20 % superior over the popular check variety GC-5.

The effects of recycling of green leaves as organic sources on loamy sand soil (Typie ustipsamments) were evaluated at Sardarkrushinagar during kharif season from 2001 to 2010 in a Randomized Block Design (RBD) with ten treatments comprising inorganic (60 kg N ha-1) and green leaves of ardu, neem, glyricidia and FYM as organic sources. Each organic source was applied to provide 30 kg N ha-1 (50% RDN) and 15 kg N ha-1 (25% RDN) as per treatment. The succeeding pearl millet crop was sown with the recommended dose of chemical fertilizers. The castor yield was highest with the application of 50% recommended dose of nitrogen through urea and 50% nitrogen through FYM along with azotobacter, which was to the tune of 26% higher than 100% recommended dose of fertilizer through urea and at par with different combined treatments of chemical fertilizers and green leaves of trees. The residual effect of the 50% RDN + 50% N through green leaves of glyricidia recorded higher seed yield of pearl millet crop and was equally effective with the incorporation of green leaves of other local trees. The responses on castor equivalent yield were non-significant. The soil organic carbon and available plant nutrients were increased due to incorporation of green leaves of trees and FYM which improved the soil health.

There is an increasing trend to require more efficient use of water resources, both in urban and rural areas. The aim of the present research work was to determine the behavior of various parameters of the pharmaceutical wastewater. The company produces bulk drugs, antibiotics, pain killers, food additives, personal care products and others. It is important for the industry to develop its own wastewater treatment system before discharging the effluent in order to meet the Gujarat Pollution control Board (GPCB) standards. Reduction of pollutants in the wastewater down to permissible concentrations is necessary for the protection of ground water and the environment. In order to design an appropriate treatment system the characteristic of the wastewater generated need to be found out with reference to the following parameters; temperature, pH, total dissolved solids (TDS), Chemical oxygen demand (COD) and ammonical nitrogen. An intensive analytical programme was followed for 4 months for monitoring pharmaceutical wastewater. Samples are collected from three points; Wet well, primary clarifier (PC) and Secondary clarifier (SC) and effluent out let to evaluate the performance of Effluent Treatment Plant. The pH, TDS, COD and NH3-N removal efficiency of Effluent Treatment Plant were found 11.71%, 92.15%, 99.47% and 90.11% respectively. © EM International Printed in India. All rights reserved.
