Field experiment was conducted during the rabi (winter) seasons of 2012-2013 and 2013-2014, to evaluate the outcome of irrigation schedules and crop establishment techniques on physiological parameters, root parameters and water productivity of wheat (Triticum aestivum (L.) emend. Flori & Paol) on sandy loam soils at CCS Haryana Agricultural University Hisar under four crop establishment techniques with three irrigation schedules allotted in strip plot design and replicated thrice. Zero tillage (ZT) and irrigation applied at CRI + IW:CPE = 0.90 registered significantly highest relative water content (RWC) of wheat leaves during 2012-2013 (83.6%) and during 2013-2014 (80.9%) as compared to conventional tillage (CT) and minimum tillage (MT). Wheat planted on bed (FIRBS) and irrigation applied at CRI + IW:CPE = 0.90 evidenced significantly higher grain yield by 12-19% and took more days from spike initiation to anthesis, anthesis to milk stage and milk to maturity during 2012-2013 and 2013-2014 crop seasons. WUE (144.6 and 155.4 kg ha-cm-1) and IWP (4.3 and 4.5 kg m-3) perceived highest under bed planting by using lower total consumptive use of water (35.71 and 35.45 cm) during the respective crop seasons. Thus the CU was around 6-12%, lower under FIRBS as compared to other crop establishment techniques. Application of irrigation at CRI + IW:CPE = 0.75 resulted in highest WUE (129.0 and 140.0 kg ha-cm-1) and IWP (4.2 and 4.4 kg m-3) with minimum water used (37.41 and 36.22 cm) during 2012-2013 and 2013-2014, respectively in contrast to other two moisture regimes. © 2017 Akadémiai Kiadó, Budapest.

Bitter gourd (Momordica charantia) is a cross-pollinated crop, so needs bees for fruit set. An experiment was conducted at the Entomological Research Farm, CCS Haryana Agricultural University, Hisar during the rainy season of 2009. Observations were taken throughout the blooming period. A total of nine bee species of three families (Apidae, Halictidae and Megachilidae) were recorded as visitors to bitter gourd flowers. Amongst these, Halictus sp., Megachile sp. and Apis dorsata Fabricius were found to be the most frequent visitors. The abundance of Halictus sp. was highest, followed by Megachile sp. and A. dorsata. Irrespective of species, the bee population was maximum at 0800-1000 h of the day. Based on pollination index (Number of loose pollen grains sticking on the body of bee x abundance x foraging rate), A. dorsata was the most efficient pollinator of bitter gourd, followed by Halictus sp. and Megachile sp. © IBRA 2012.

Haryana has emerged as an important state for Rice & Wheat production in India contributing significantly in the central pool. Mechanized combine harvesting technologies, which have become common in Rice Wheat System (RWS) in India, leave behind large quantities of straw in the field for open burning of residue. Besides causing pollution, the burning kills the useful micro flora of the soil causing soil degradation. There is no field survey (Girdawari) data available with the Government for the areas where stubble burning is taking place. The present paper describes the methodology and results of wheat and rice residue burning areas for three districts of Haryana namely Kaithal, Kurukshetra and Karnal for the year 2010 using complete enumeration approach of multi-date IRS-P6 AWiFS and LISS-III data. In season ground truth was collected using hand held GPS and used to identify area of burnt wheat/rice residues, associated crops and land features. After geo-referencing the satellite images, district images were masked-out and multi-date image data stacks were created. Normalized Difference Vegetation Index (NDVI) of each date was generated and used at the time of classification along with other spectral bands. The non-agricultural classes in the image included: forest, wasteland, water bodies, urban/settlement and permanent vegetation etc. The vector of these non-agriculture classes were extracted from the land use, imported and mask was generated. During the classification non-agriculture area was excluded by using mask of these classes. From this the agricultural area could be separated out. The area was estimated by computing pixels under the classified image mask. In season multi-date AWiFS data along with available single-date LISS-III data between third week of April to last week of May are found to be useful for estimation of wheat residue burning areas estimation. The data between second week of October to last week of November is useful for estimation of rice residue burning areas estimation at district level. © 2013 Indian Society of Remote Sensing.

The present research was conducted with the objective to study the variation in seed oil content among five seed sources across diverse agro-climatic conditions and storage behaviour of seeds up to two years. Seeds collected in May 2010 were stored up to May 2012 at three moisture levels (6%, 9% and normal), two temperature regimes (room temp. and -5°C) and three types of containers (cloth bags, polythene bags and air tight containers). The parameters of oil content (%), germination (%), seedling length (cm), seedling dry weight (mg) and seedling vigour (index-I & II) were measured. Seeds collected from the test trees of different agro-climatic zones were bulked zone-wise (seeds collected from all the 10 test trees from one agro-climatic zone were bulked). The seeds from each agro-climatic zone were divided into three equal parts. The maximum oil content was in RJ-7 agroclimatic zone and minimum in PB-3 agro-climatic zone. The oil content decreased with passage of time. Decline in the seed oil content was not significant up to a period of 12 months but by 24th month of storage the oil content declined significantly up to 6%. There was no germination after 12 months in the seeds stored at room temperature with normal and 9% moisture content irrespective of the type of containers used for storage. Seedling vigour declined significantly with increasing period of storage. Seeds stored in polythene bags and air tight containers had higher seedling length than cloth bag storage. Seeds with 6% moisture level stored at -5°C retained viability up to 16 months in air tight containers. The oil content was maximum (34.75%) in RJ-7 agro-climatic zone.

Wheat grain yield is limited due to terminal heat stress. Inconsistency of the previous results reflects the interactions between genotypes and environments. In North West Plain Zone (NWPZ), where the hot, dry wind is frequent during grain filling, wheat cultivars suffer from loss of grain weight because of low grain filling rate. A field study was carried out under late sown conditions in NWPZ to evaluate the phenological variations using heat-accumulated system and its relation with yield in twenty five wheat genotypes. Grain yield was positively correlated with days to heading, biological yield, harvest index and grain number per spike in both timely (TS) and late sown (LS) varieties, while grain weight and flag leaf area also showed positive correlation with grain yield in LS varieties. Grain growth rate (GGR) at 14 and 28 days after anthesis (DAA) showed positive correlations with grain weight in TS, and in LS genotypes flag leaf area was positively correlated with GGR at 14 DAA. Increasing days to heading resulted in higher grain yield, while increasing grain filling duration has little effect. PBW 343 and WH 711 in TS varieties and WH 1022 and PBW 373 in LS group had highest grain yields in their respective groups among the genotypes studied. These genotypes tended to have relatively longer pre-heading periods with medium maturity. The results of this study indicate that NWPZ adapted cultivars would have long pre-heading periods, moderate grain filling duration, high grain filling rates and mature early to avoid late-season drought and high-temperature stresses to attain high yields. Therefore, high yielding wheat cultivars adapted to subtropical environments can be develop by selecting the genotypes with medium maturity and a relatively long time to heading. © 2014, Indian Society for Plant Physiology.

Short- Term effect of different concentrations of NaCI on callus cultures of Jatropha curcas was investigated at different concentration of NaCI (0,20,40,60,80,100 mM). Results showed a decrease in fresh weight of callus cultures when subjected to increasing concentration of salt in the medium. Callus morphology correspondingly changed from off-white to blackish-brown above 40mM to acutely necrotic stage at 100 mM NaCI .The callus cultures after recurrent selection (at 20mM for 20 days) were transferred to salt free optimized callus regeneration medium expressed 90.0% recovery. The callus placed in 40mM, 60mM concentration of NaCI exhibited moderate tolerance and showed 64.0% and 56.0% recovery. In 80mM concentration, callus showed moderate susceptibility and showed 6.9 % recovery of callus. © Triveni Enterprises,Lucknow(India).

Many bacterial pathogens can now be detected in samples of various kinds without the need to first culture the organism and phylogenetic relationships by using PCR-based methods. PCR-based genotyping technologies are simple and fast. Under the present investigation, the amplified gel electrophorized product (approx. 500 bp), stained with Ethidium bromide was visualized under U.V. light in gel documentation system. The amplified 16S rDNA was digested with two restriction enzymes SauIIIA and Hinfl at 37°C for 2 h to generate amplified ribosomal DNA restriction analysis (ARDRA) profiles, both the restriction enzymes generated 2-3 fragments in bacterial isolates; these fragments were scored by comparison to a low molecular DNA Ladder (50 bp) and analyzed by 1/0 clustering method of the NTSYSpc2.0 programme then a dendrogram displaying hierarchical associations among all isolates was generated. On the basis of similarity coefficient the isolates were divided in five major groups (A, B, C, D and E). Group A and E were found most divergent which have genotypes S. aureus and Streptococcus grp. Q1, respectively. The genotypes Kl. oxytoca and A. hydrophila has 83% similarity in group B, whereas P. flourescens and P. aeruginosa have 99% similarity in group D.

A field experiment was conducted in two years old fruit and tree species namely shisham (Dalbergia sissoo) + aonla (Embilica officinalis), shisham (D. sissoo) + guava (Psidium guajava), khejri (Prosopis cineraria) + aonla (E. officinalis) and khejri (P. cineraria) + guava (P. guajava) during 2007-08 and 2008-09 planted at a spacing of 6m×6m. The crop sequences, viz. ridgegourd (Lifa acutangula) - Tomato (Solanum lycopersicum), moongbean (Vigna radiata) - fallow and cluster bean (Cyamopsis tetragonoloba) - fallow were raised in the interspaces of the trees. Ridgegourd and tomato were raised with drip irrigation, while moongbean and cluster bean were raised as rainfed. The trees and crops were subjected to three drip irrigation treatments, viz. T1 (100% ETc), T2 (70% ETc) and T3 (40% ETc) with three replications per treatment. Yield of intercrops was not affected by the different silvi-horti systems. The irrigation treatments influenced the yield of crops and growth of trees. Maximum yield (39323 kg/ha) of tomato and growth of trees was recorded under 100% replenishment of water except in case of shisham, where maximum height (803.0 cm), diameter (15.4 cm) and crown spread (550 cm2) was recorded under 70% replenishment of water after 48 months of plantation. Maximum irrigation water use efficiency (19.34 g/l) was recorded for ridgegourd under 40% replenishment of water when grown in association with khejri + aonla. Intercropping of tomato and ridgegourd with khejri + guava was found most remunerative with maximum NPV, BC ratio and net returns after sole cropping.
