Author:M.R.Anita Ands. Lakshmi
Volume: 13 | Issue no: 2-2017 | Pagination: 1-7
Field experiment was conducted at the Instructional Farm, College of Agriculture, Vellayani, Thiruvananthapuram during January 2012 to March 2014 to find out the effect of grass-fodder cowpea mixtures and row ratio on the growth characters, yield and economics of fodder grasses and fodder cowpea in open and in partial shade. The investigation was conducted as two separate experiments, one in open and another in shaded situation (25-35 % shade). The experiment was laid out in RBD with three replications, comprising of two grasses [G1-Hybrid napier (Suguna), G2-Guinea grass (Harithasree)], two fodder cowpea varieties (V1-COFC-8 (open and shade), V2-UPC-622 (open), UPC-618 (shade) and three grass legume row ratios (R1-1:1, R2-1:2, R3-1:3). The results indicated the superiority of the grass legume mixture of hybrid napier cv. SUGUNA and with both the fodder cowpea varieties in the grass legume row ratio of 1:2 with respect to growth characters, green fodder yield and net returns. Based on the results, it can be concluded that hybrid napier cv. SUGUNA intercropped with fodder cowpea varieties COFC-8 and UPC-622 in open condition and with COFC-8 and UPC-618 in partial shade (30 %) in the row ratio of 1:2 is the best for obtaining maximum yield, quality and net returns.
Rainwater Harvesting In North-East India: A Strategy For Alleviate Water Shortage
Volume: 13 | Issue no: 2-2017 | Pagination: 434-436
Rainwater harvesting provides an independent water supply during regional water restrictions and in developed countries. There are different ways in which rainwater can be harvested. This water can be used for direct consumption as also for recharging groundwater through simple filtration devices. Water can be collected in tanks that have cement slabs built at their base to prevent the water from seeping underground. Rainwater harvesting is more popular in Meghalaya and Mizoram. The main objectives of the paper are: (a) To study the importance of rainwater harvesting; and (b) To identify the situation of rainwater harvesting in Northeastern India.
Phytoseiid Mites: Successful Biocontrol Agents Of Mite Pests In Protected Vegetables
Volume: 13 | Issue no: 2-2017 | Pagination: 424-433
Biocontrol success has forced several countries to use phytoseiids e.g., Chilean mite, Phytoseiulus persimilis Athias- Henriot (Acarina: Phytoseiidae) against mite pests in protected vegetable crops. The characteristics like more oviposition period, sex-ratio (female: male), longevity, consumption capacity, prey searching capability and survival at low prey densities have revealed P. persimilis a successful predator of two-spotted mite, Tetranychus urticae Koch (Acarina: Tetranychidae). Introduction of prey and predatory mite together or predatory mite slightly late gave better results than in case where predatory mite was introduced much later. Biocontrol failed in case where chemicals were applied except where predators reintroduced and chemicals were not re-applied. Predation took few days to eliminate largest number of mite pests at high temperature. At low relative humidity peak predation was noticed as there was more prey predator interaction. However, prey activity declined to zero while predator activity prolonged at high relative humidity. This review article includes various studies carried out on use of phytoseiid mites as biocontrol agents of various mite pests on protected vegetables.
The Potential Of Jute Crop For Mitigation Of Greenhouse Gas Emission In The Changing Climatic Scenario
Volume: 13 | Issue no: 2-2017 | Pagination: 419-423
Global warming is steadily increasing and impacting on highly vulnerable developing countries. Agriculture which is an essential sector for most of developing countries contributing to climate change with greenhouse gas emissions (GHG) and suffering from the effects of climate change. The challenge of feeding the population and reducing agricultural GHG emissions requires the successful transfer of climate-friendly agricultural and land use practices to farmers serving adaptation and mitigation needs. Jute crop have the potential to absorb and fix carbon dioxide from the atmosphere, save for the carbon released back through the application of agro-chemical inputs and use of fossil fuels in the management of jute production systems. The paper reviews the relationship between carbon sequestration, jute crop management systems and the effects on greenhouse gases. This may help in identifying the point to improve environmental efficiency and accessing opportunities for carbon trading, contribute to the development of sustainable technologies to manage GHG emissions and global warming

Author:Harish H. Deshpande*, Harshada P. Deshmukh And Shrinivas H. Deshpande1
Volume: 13 | Issue no: 2-2017 | Pagination: 410-418
The sugarbeet is an important commercial crop for temperate region and long back tropicalized sugarbeet varieties have been emerged out in the country due to the effort of plant breeders. The cultivation of tropical sugarbeet in India is not a new practice but not yet popularized still; the southern states such as Maharashtra and Tamil Nadu have been already succeeded in its cultivation. The cultivation of sugarbeet requires a sound knowledge of sugarbeet agronomy and one should know the agrotechniques to obtain higher yield and sustain the productivity of sugarbeet. Considerable research efforts made by researchers worldwide in developing the production packages and these agro-techniques may motivate the new researcher to think new areas of research in India. Hence, considerable effort has been made here to review the various agro-techniques of sugarbeet with respect to growth, yield, economics and quality and it is the key subject, reviewed and presented below.

Volume: 13 | Issue no: 2-2017 | Pagination: 403-409
A field experiment was conducted to characterize finger millet recombinant inbred lines (RILs) for drought tolerance. A set of 150 RILs with two parents IE 2912 and IE 2885 used were used to characterize for drought tolerance traits such as total leaf area, root length, root volume, moisture retention capacity (MRC) and SPAD chlorophyll reading (SCMR). Parent line IE 2912 was superior to IE 2885 for all the traits and both parents differed significantly for all traits except MRC and SCMR. In mapping population, root traits, leaf traits, showed traits showed normal distribution around the mean and showed continuous variation indicating their quantitative nature. Since identified parental lines and mapping population developed are differing significantly they can be utilized in identifying markers linked to drought traits.

Volume: 13 | Issue no: 2-2017 | Pagination: 390-402
The experiment was laid out in a Factorial Randomized Block Design with twelve treatments and replicated thrice. Results indicate that the seed inoculation with Rhizobium showed some good results increasing numbers of nodules and uptake of nutrients due to inoculation. Significant effects were observed in plants growth attributes due to presence of phosphorus and uptake of phosphorus increased due to presence of sulphur @ 20kg ha-1ultimately resulting in good yield. However, plant heights (66.00cm), Number of branches plant-1 (4.82), Number of nodules plant-1 (5.83), Number of grains pod-1 (12.56), test weight (51.03g) and grain yield (12.39 q/ha) were found significantly affected by the application of Rhizobium inoculation, application of 45kg phosphorus through DAP and 20kg sulphur through Gypsum ha-1. Cost benefit ratio was also found (2.22) on higher side.

Volume: 13 | Issue no: 2-2017 | Pagination: 385-389
An experiment studying the effects of various levels of fertigation duration and fertigation levels on jaggery quality parameters of sugarcane using the variety CO86032 over two crop seasons (2014-15 and 2015-16) was conducted at ZARS, V.C. Farm, Mandya. Results revealed that jaggery quality parameters like juice extraction per cent, net rendament value, reducing sugars in jaggery and jaggery hardness did not differ significantly due to fertigation duration, fertigation levels and their interaction. Whereas, significantly higher jaggery recovery (13.82 and 13.45 %) and jaggery yield (31.92 and 28.19 t ha-1) was recorded with fertigation duration upto 9.5 months in plant and ratoon cane at harvest, respectively. Jaggery recovery and jaggery yield significantly not influenced by fertigation levels. The interaction between fertigation duration and levels were significant. Fertigation upto 9.5months with 125 per cent RDF recorded significantly higher jaggery recovery(13.96 and 13.55 %) and jaggery yield (32.21 and 28.91 t ha-1) in plant and ratoon cane at harvest, respectively. Stastically, at par results were observed with fertigation upto 9.5 months with 100 per cent of RDF and fertigation upto 9.5 months with 75 per cent of RDF. Normal method of sugarcane cultivation with surface irrigation with 100 per cent of RDF soil application recorded lower jaggery recovery (11.87 and 11.10 %) and jaggery yield (16.70 and 13.70 t ha-1) of plant and ratoon cane at harvest, respectively. Experimental results clearly indicated that sub surface drip fertigation (SSDF) helps to increase the jaggery quality parameters over normal practice of sugarcane cultivation.

A field experiment was conducted under the temperate conditions of Kashmir during Rabi season 2011-12 and 2012- 13 to study the effect of integrated weed management on growth, yield attributing characters, yield and economics of wheat (Triticum aestivumL.). The results revealed significant increase in grain yield and growth characters, like crop emergence/mm row length, No. of tillers / m row length at 60 DAS and plant height (cm) at 60 DAS with isoproturon @ 1 kg a. i /ha at 32 days after sowing + hand weeding at 30 days after sowing during both the years. Among the weed control measures isoproturon @ 1 kg a. i /ha at 32 days after sowing + hand weeding at 30 days after sowing recorded higher grains/ear, 1000 grain weight (g), highest grain yield ( 4.22 tonnes/ha) as well as straw yield (6.10 tonnes/ha) which was at par with the weed free but; isoproturon @ 1 kg a. i /ha tank mix with 2, 4-D @ 0.5kg a. i /ha at 32 days after gives significantly highest net returns Rs. 817.7 and Rs. 919.7 during 2011-12 and 2012-13, respectively. The higher net returns under isoproturon @ 1 kg a. i /ha tank mix with 2, 4-D @ 0.5kg a. i /ha at 32 days after sowing was due to lower cost of herbicides.

Author:A. A. Bagul* And M. M. Masu
Volume: 13 | Issue no: 2-2017 | Pagination: 371-377
The three varieties of custard apple were subjected to various preharvest chemicals and plant growth regulators treatments, viz., CaCl2 @ 2 %, KNO3 @ 2 %, GA3@ 50 mg/l, NAA @ 50 mg/l and no spray. Then mature, uniformed sizes fruit were harvested and observation were recorded under ambient storage condition. Balanagar recorded maximum fruit weight (180.32 g), volume (109.42 cc) and pulp weight per fruit (90.52 g) while minimum peel weight per fruit (53.87 g) and seed weight per fruit (10.43 g) recorded in Local variety at harvest. GA3@ 50 mg/l were found to best since they have maximum fruit weight (159.60 g), volume (96.85 cc) and pulp weight per fruit (79.54 g) at harvest. In case of fruit diameter (7.39 cm, 7.09 cm) in both factors were recorded maximum at 3rd day of storage. CaCl2 @ 2 % recorded minimum PLW (23.54 % at 6th day) and spoilage percentage (32.22 %) and maximum fruit firmness (0.25 kg/cm2 at 6th day), shelf-life of fruits (7.25 days) and marketable fruit percentage (67.78 %) during storage. Thus, it can be inferred from the study that Balanagar variety and GA3@ 50 mg/l rated as most acceptable and superior, over all the other treatments in term of physical parameters and in term of quality and shelf-life CaCl2 @ 2 % treatment observed during ambient storage.
