Abstract

Thirteen genetically diverse parents collected from the different parts of the country and their 36 crosses generated by using line x tester mating design, was undertaken to study the heterosis and heterobeltiosis for fruits yield and its contributing characters in okra. Majority of the hybrids exhibited significant and positive heterosis over mid-parental value and over better parent for most of the traits. Seventeen hybrids showed significant and positive heterobeltiosis for fruit yield per plant. The cross combination Parbhani Kranti x D-1-87-5 exhibited the highest heterobeltiosis (184.27%) for fruit yield per plant. Manifestation of heterosis by this particular cross combination was also realized for all the characters except for days to flowering and number of nodes per plant. The heterosis over better parent for yield per plant was mainly due to longer and thicker fruits coupled with more number of fruits per plant.

Abstract

Aonla is an important fruit crop because of its large-scale use in Ayurvedic and Homoeopathic medicines. The fruit is highly nutritive and richest source of vitamin C among fruits except Barbados cherry. Murabba, Chyavanprash, pickles, chutney, sauce, candy, dried chips are prepared from aonla fruit. Its tree is quite hardy, prolific bearer and highly remunerative even without much cares. Aonla is most suitable for cultivating under agro-climatic conditions of Rajasthan. It has higher productivity per unit area even in the wastelands so it has bright future for exporting to European countries. findings of present study, inferred that majority of the farmers had medium knowledge level about recommended aonla production technology. Knowledge level of the farmers was found to be positively significant with their occupation, education, social participation, size of holding, irrigation potentiality and sources of information utilized.

Abstract

To accelerate the production of crop, ICAR has started FLD programme through KVK. Latest recommended package of practices are demonstrated on farmers field under direct supervision of extension educationist / scientist. With a view to know the follow up action and feedback regarding FLD on Kharif groundnut production technology by KVK was under taken. Four villages in Deesa taluka where FLDs on groundnut crop were selected purposively. A total of 70 beneficiary farmers were randomly selected from these four villages. The major follow up action taken by KVK was visit to FLD (100%), but less action carried out for organization of FLD meeting (2.86%) on farmers field. On the other hand the major follow up actions taken by beneficiary farmers were liaison with KVK after FLD and increase area under groundnut (100%), which indicate the accomplishment of FLD process. The feedbacks of the beneficiary farmers were more regarding visit to KVK after the FLD (100%) and 82.85 per cent for contact withs programme coordinator of KVK. The major reason of visit to KVK were gaining the information of improved varieties of various crops (85.71%) with ranked first.

Abstract

The present study was conducted in 4 villages of Deesa taluka where FLDs on groundnut crop were conducted by KVK. Groundnut is one of the most important crops among the different oilseed crops grown in Gujarat. The finding of the study indicated that the extent of adoption of the demonstrated groundnut production technology was medium to high among the majority of the respondents from beneficiary farmers (92.86%) and non-beneficiary farmers (81.42%). Significant difference between beneficiary and non-beneficiary farmers with respect to their extent of adoption of improved demonstrated groundnut production technology were found. Beneficiary farmers had higher level of adoption about improved groundnut crops practices as compared to non-beneficiary farmer. The present study concludes that education, social participation, farm size, annual income, extension participation, source of information, scientific orientation and knowledge of the beneficiary farmers were positively related with extent of adoption of improved demonstrated groundnut production technology.

Abstract

Investigation was carried-out to assess the selection indices in 40 genotypes of wheat (Triticum aestivum L.) in limited irrigation under late sowing condition. Sixty-three selection indices, involving grain yield per plant and five yield components, were constructed using the discriminant function technique. The efficiency of selection increased with the inclusion of more number of characters in the index. The selection index based on six characters viz., grain yield per plant, days to maturity, number of productive tillers per plant, number of grain per main spike, biological yield per plant and harvest index under limited irrigated condition exhibited maximum gain and relative efficiency. It is expected that grain yield could be improved if due consideration is given to these traits in future breeding programme of wheat.

Abstract

PMRY is a scheme launched by GOI in 1993 for the educated unemployment youths. The success of any programme remains with the proper utilization of assistance provided for the objectives. The study reveals that “inadequate supply of assistance” was major constraints followed by “disbursal of assistance” is delayed to beneficiaries. So, it is suggested that to overcome from these constraints there should be better co-ordination between official and beneficiaries.

Abstract

Present study was carried out on chickpea to find out the incidence of pod borer as well as monitoring of pod borer at Pulses Research Station, Junagadh Agricultural University, Junagadh (Gujarat) during Rabi seasons 2011-12, 2012-13 and 2013-14. The results revealed that larval population of Helicoverpa armigera was varied from 0.86 to 2.55 larvae/mrl at 30 DAS. More or less similar pattern was observed at 45 and 75 DAS, while larval population varied from 1.45 to 3.20 and 1.26 to 3.02 larvae/mrl, respectively. At 60 DAS treatment D₂V₁ noted lowest larval population (0.58 larvae/mrl). The treatment D₁V₃ recorded the lowest pod damage of 3.66, 3.95, 4.03 and 3.88 per cent in 2011-12, 2012-13, 2013-14 and pooled results, respectively. Seed yield was varied from 825 to 1612 kg/ha. The activity of male moths began from 50^th standard week of December to 9^th standard week of February / March. The peak period was observed from 1^st standard week to 4^th standard week of January.

Abstract

ICAR has started FLD programme through KVK, to accelerate the production of crop. Latest recommended package of practices are demonstrated on farmers field under direct supervision of extension educationist/scientist. The present study was conducted in 4 villages of Deesa taluka where FLDs on groundnut crop were conducted by KVK. Groundnut is one of the most important crops among the different oilseed crops grown in Gujarat. Cent per cent beneficiary farmers were having medium to high level of awareness about the front line demonstration. On the other side 67.14 per cent of non-beneficiary farmers had medium to high level of awareness about front line demonstration. There was significant difference between beneficiary and non-beneficiary farmers with regard to their awareness about front line demonstration. The main constraints perceived by the beneficiary farmers were; non remunerative price for groundnut, high cost of inputs viz., seeds, fertilizers and chemicals, timely unavailability of inputs, poor marketing facility and can not stored farm production for long period to fetch high price.

Abstract

An in vitro propagation system developed for castor-bean (Ricinus communis L.) through hypocotyl derived callus cultures. Seeds were surface sterilized with 5 per cent bavistin for 30 min followed by 0.01 per cent HgCl₂ for 4 min to obtain in vitro seedlings germinated with growth regulator free MS medium. The impacts of different concentrations of auxins and cytokinins were evaluated for callus induction, shoot proliferation and ischolar_main induction. Hypocotyls were excised from 10-12 days old in vitro seedlings and were cultured on Murashige and Skoog's (MS) medium supplemented with different concentration of BA, KIN and 2IP. White compact, nodular organogenic callus was obtained on the MS medium fortified with B₅ vitamins and 1.0 mg/l BA (80.84%) or 2.0 mg/l BA(80.17%). Shoot induction from the callus cultures was achieved on MS medium with 0.5 mg/ l KIN + 0.25mg/l BAP (75.00%). Use of 0.2 mg/l GA₃ in combination with 0.5 mg/l KIN and 0.25 mg/l BAP induced maximum number of shoots per explants (7.00) as well as shoot length (6.49cm). For ischolar_main induction, in vitro shoots were transferred to ischolar_maining media containing IAA, IBA and AgNO₃ singly or in combinations but ischolar_main induction was not achieved even after 30 days of culture.

Abstract

F₂ generation of eight crosses of bread wheat were grown under timely and late sowing conditions to study the genetic correlation for grain yield and its components. Under timely sowing, negative and significant association with grain yield per plant was found in hybrid RWP 2002-2 × LOK-1 for days to heading, in GW 9715 × K 9102 for days to maturity and in AKAW 2862-2 × MACS 2496 for plant height. However, significant and positive relationship was displayed between grain yield per plant with number of effective tillers per plant in all the crosses except crosses CLN 5 × GW 322 and GW 9715 × K 9102. Positive and significant association of grain yield per plant with biological yield per plant and harvest index was observed in all the crosses except cross 3 and crosses 3 and 7, respectively. In case of late sowing, significant and negative genetic association for developmental traits was found for days to maturity in cross RWP 2002-2 × LOK 1 and for plant height in AKAW 2862-1 × MACS 2496, CLN 1 × GW 273 and P 11616 × PBW 524. While positive and significant association of grain yield per plant with number of effective tillers per plant, length of main spike, number of grains per spike, grain filling period and biological yield per plant was observed in all the crosses except cross 3 for length of main spike and cross 2 for number of grains per spike under late sowing. Above said yield contributing characters are useful for the indirect selection for the improvement of grain yield per plant under respective environment in bread wheat.
