SUMMARY

Eucalyptus, a member of family Myrtaceae and it is one of the most prime species in agroforestry and clonal planting material for more returns in short rotation most popular in farmers due to its fast growth. It can adapt a varied range of edaphic and climatic and its cultivation is considered an eco-friendly approach to cope up with the salinization. In Haryana, agroforestry practices vary according to the agro-climatic zones and socio-economic status of the farmers, tree diversity, existing cropping pattern and availability of irrigation water. The present investigation was carried out at the Forestry Research Farm during the rabi season of 2019-20 at CCS Haryana Agricultural University, Hisar to found effect of different spacing of clonal Eucalyptus plantation on the performance of wheat and barley crops in saline condition in Semi-arid environment. Therefore, field crops namely wheat (Triticum aestivum) HD- 2967and Barley (Hordeum vulgare) BH-393 were sown under clonal eucalyptus 4m x 2m and 5m x 2m spacing and in open (devoid of trees) following randomized block design with seven replication during rabi season. Growth, yield attributes and yield were recorded at harvest. The maximum plant height (71.58 cm) of wheat was recorded under 5m x 2m spacing as compared to in 4m x 2m spacing. The other parameters viz, no. of effective tillers /m2, days taken to maturity (no.), number of grains/spike, test weight (g) showed similar pattern under 5m x 2m spacing in the study. Among different spacing , the maximum grain yield (3.01 t/ha) and straw yield (3.94 t/ha) was recorded in spacing 5m x 2m .The plant height (84.59cm ) of barley was found higher under 5m x 2m spacing. Similarly, other parameters viz, no. of effective tillers / m2, days taken to maturity (no.), test weight (g), and grain yield in barley were found higher under 5m x 2m spacing as compared to 4x2m spacing. The crop indicates that 5m x 2m spacing is more appropriate spacing of clonal Eucalyptus plantation from productivity and practically fruitful aspect.

SUMMARY

India is the major producer of cluster bean (Cyamopsis tetragonoloba L. Taub.) contributing about 82 per cent of the total production of the world and bacterial leaf blight is one of its most destructive disease caused by Xanthomonas axonopodis pv. cyamopsidis. It causes yield loss of 50–70 per cent of cluster bean under severe conditions, if appropriate measures to combat the disease are not taken timely. The disease effects crop productivity in all growing regions of the world. In Haryana state, the bacterial blight has been recognized as most important limiting factor in reducing the yield. It is both seed borne and air borne in nature and affects all above ground parts of plant. Chemicals have played significant role in management of the disease but their use in excessive amount led to detrimental effect on the ecosystem such as residual toxicity, harmful effect on living beings and the whole environment, especially on the beneficial predators, parasites and microorganisms. Keeping this in view, the present investigation has been devised on disease management using various biorational components during 2020-2021 at Hisar. It was observed that Azadirachta indica was found most effective with 18.04 per cent growth inhibition followed by Zingiber officinale under in vitro conditions. Under screen house conditions, minimum per cent disease incidence (PDI) of 26.67 per cent was observed in treatment of Azadirachta indica @ 25 per cent w/v followed by treatments of Zingiber officinale @ 25 per cent w/v.

SUMMARY

The present study was carried out at Agricultural Research Station, Keshwana, Jalore during winter cycle 2018-19 and 2019-20 on “Effect of different levels and foliar application of nitrogen in oat under transitional plain of Luni basin”. The soils of the experimental fields were loamy sandy in texture, alkaline in reaction, low in organic matter and nitrogen content and low to medium in Phosphorous medium to high in potassium content. The experiment used a split plot design with three treatment in main plot and three plot in sub plot repeated with three times. The experiment included three levels of nitrogen, namely 50 %, 75% and 100 % of recommended nitrogen i.e. F₁, F₂ and F₃ and 4 urea spray namely water spray, 2% urea spray at 15, 30 and 45 DAS was used. Application of nitrogen as a basal and foliar had a significant effect on the growth, green and dry fodder yields of the oat. Application of 100% RDN showed a significant higher results with respect to tillers per plant, plant height, CGR, RGR, Dry matter percentage during both the year of experiment but it was recorded at par with the 75% RDN during both the years. Green and dry fodder yields during 2018- 19 were recorded significantly higher with the Application of 75% RDN, while in succeeding year it was recorded higher with 100% RDN. Foliar spray of urea 2% at 30 DAS recorded significant effect on the growth and yield parameters of the fodder oat but it was at par with the 45 DAS. Positive linear relationships were observed with respect to nitrogen application and green (R²= 0.7826) and dry (R²= 0.8019) fodder yields of oat.

Key words: Oat, fodder, nitrogen, growth and yield

SUMMARY

Present investigation was carried out in dual purpose sorghum, HC 308 during Kharif, 2021 at CCS HAU, Hisar in replicated four times at four successive date of sowing at seven days interval to study the impact of date of sowing on incidence of sorghum stem borer and shoot fly in sorghum crop. Number of eggs laid by sorghum shoot fly at 7 and 14 days after emergence (DAE) was lowest in the crop sown on 21st July (0.67 and 1.33, respectively) and was highest in the crop sown on 11th August i.e., 3.00 and 4.00, respectively. Sorghum crop sown on 21st July showed significantly lowest per cent of deadheart incidence (12.33 and 15.39%) while, crop sown on 11th August showed higher per cent of deadheart incidence i.e., 25.52% and 29.78% at 21 and 28 DAE, respectively. Deadheart per cent by sorghum stem borer was recorded lower (16.42%) in crop sown on 21st July as compare to crop sown on 11th August (27.79%) at 45 DAE. Therefore, rather than rushing to apply different insecticides, date sowing of sorghum crop should primarily be kept in mind to avoid the more of an attack from sorghum shoot fly and stem borer.

SUMMARY

India has vast resources of livestock and poultry, which play a vital role in improving the socio-economic conditions of rural masses. The livestock industry in Rajasthan is highly dependent on the availability and affordability of fodder quality. This research aims to analyse and understand the market dynamics of dry fodder in Rajasthan mandis i.e., Bikaner and Chomu from 2018 to 2023. A thorough understanding of pricing trends is crucial for stakeholders in the livestock industry. This study showed that for wheat dry fodder, prices were low during April-May whereas for Rice, Bajra, Sorghum and cluster bean dry fodder, period of October-November is best to purchase at low price and Khejri loong prices was low during June-July. This paper outlines the trend of cereal, millets and conventional dry fodder market prices in Rajasthan mandi for last six years, their comparative study and reason of price fluctuation.
