Profitability of Cauliflower Cultivation in Sonepat District of Haryana
Cauliflower (Brassica oleracea) is one of the important cruciferous vegetable crops of India. It is widely cultivated throughout the sub-tropical parts of north India. The present investigation has analyzed the costs, returns and marketing in Sonepat district of Haryana during the year 2017-18 on the basis of highest production. A total of thirty farmers were randomly selected from the various villages of Sonepat District of Haryana. Results indicated that cost of cultivation of cauliflower per hectare was Rs.211685. The average yield of cauliflower per hectare was observed 246 quintals on sample farms. The net profit per hectare was Rs.96799. The major findings of this study revealed that production of the cauliflower was profitable. Benefit cost ratios of cauliflower was 1.46. The study was found that direct marketing of cauliflower more profitable in Channel-IV Producer-consumer among all other marketing channels due to the non-existence of intermediaries between the producer and ultimate consumer.
Marketing and Constraints faced by Kinnow Growers in Sirsa District of Haryana
Kinnow is being widely cultivated in North-Western part of India comprising the states of Punjab, Haryana and Rajasthan. The present study was conducted in Sirsa district of Haryana. A sample of thirty kinnow respondents was taken purposively from various villages in Mandi Dabwali block of Sirsa district of Haryana. A comparison of price spread through different marketing channels has revealed that producers’ share in consumers’ rupee was the highest (about 93.05%) in channel-V, due to self-sale in the local market. The marketing efficiency has been found to be highest in channel-V. The producer got maximum benefits in channel-V, therefore this channel should be followed to make producer highest beneficiary; although this channel has its own limitations. The major problems faced by the farmers in the production of kinnow are indicates that 90.00 per cent of the respondents were claiming high cost of pesticides, high cost of seed (83.33%), high cost of fertilizer (80.00%), lack of knowledge of recommended fertilizer doses (80.00%), lack of knowledge about the control measures for various pests and diseases (76.67%). These were followed by difficulty in identifying the pests and diseases (66.67%), shortage of electricity power for processing (73.33%), lack of technical manpower (66.67%), problems in the arrangement of finance (63.33%), lack of processing unit (60.00%), lack of good quality packaging material (53.33%),fluctuation in raw material and procurement (50.00%), constraints regarding location of site (46.67%).
Performance of 1-Aminocyclopropane-1-Carboxylic Acid Deaminase Containing Pseudomonas fuorescens for Enhancing Growth and Yield of Maize (Zea mays L.)
Pseudomonas (P) fluorescens promote plant growth by lowering the endogenous ethylene synthesis in the roots through their 1-aminocylopropane-1-carboxylate-deaminase (ACCD) activity. However, in the environs of the roots may decrease the efficiency of these P. fluorescens by stimulating ACC- oxidase activity resulting in greater ethylene production by the roots. So this study was designed to assess the performance of P. fluorescens containing ACC-deaminase for improving growth and yield of maize. In total, 16 isolates of P. fluorescens obtained from fermentor under different temperature (25, 28, 31, 34° C) and pH (6.7, 7.2, 7.7, 8.2) based on ACCD activity and population kinetics. It was observed that P. fluorescens 06 isolate significantly enhanced the seed emergence by 31.1 and 28.7% at 05 and 09 days after sowing (DAS), respectively, while the isolate of P. fluorescens 10 increased emergence 30.8% at 07 DAS over control. The isolates P. fluorescens 10 significantly increased number and length of roots by 30.0, and 22.5%, respectively at 55 DAS and P. fluorescens 06 isolates significantly increased fresh and dry weight of brace roots by 25.0, and 26.2%, respectively over control. The isolates of P. fluorescens 10 at 75 DAS significantly increased root number, fresh, and dry weight of brace root by 30.2, 28.1, and 25.7%, respectively and isolates P. fluorescens 06 significantly increased root length 22.4% over control. The maximum plant height recorded with isolates P. fluorescens 10 by 29.3, and 29.1% at knee stage and silking stage, respectively and P. fluorescens 06 at tasseling stage by 31.1%, over control. Application of isolates P. fluorescens 06 accounted for highest number of leaves at knee height and silking stage and P. fluorescens 10 at tasseling stage by 32.6, 27.2 and 31.1% over control. Whereas, the application of isolate P. fluorescens 06 yielded 11.8, 13.3 and 21.7% higher total chlorophyll at knee height, tasseling and silking stage, respectively over control. Application of P. fluorescens 06 isolate observed significantly 19.2, 28.0, 24.6, and 26.3% higher fresh and dry weight over control at knee height and silking stage respectively, at tasseling stage the response of P. fluorescens 10 isolate yielded 26.6 and 23.8% higher fresh and dry weight over control. The isolates P. fluorescens 06 significantly increased the grain and stover yield 24.9 and 31.6% of maize over control.
Municipal Solid Waste Management Issues, Policies and Plan Strategy in Nigeria
Over the years, municipal solid waste management is a major problem in Nigeria. This problem is glaring in most cities where several municipal solid wastes of various dimensions are dump illegally without treatment. Beside the wide spread, illegal disposal and open dumping which has been the practice, landfills in Nigeria are in a dilapidated condition and suffer neglect due to the absence of authority support, and therefore need to be close. Solving these issues alongside the upgrading or the establishment of new landfills remain a problem. A review was performed from previously published studies, and keywords municipal solid waste management, policy implementation, plan strategy was applied from the database of Science Direct, Sage, Public Health, resulting to the selection of 138 scientific papers. A careful examination of the abstract led to the selection of 109 original papers. Only peer reviewed scientific papers published in English over the last 21 years (1998-2019) were considered for the review. Onsite visit to some selected landfills were also carried out for a period of two years (2017- 2019) to ascertain the condition of the landfills. It has been observed that most of the landfills are not in operational. The results show that population increased more rapidly, which aggravated waste problem. Approximately, 45% of the population live in cities and produce about 41,000 tonnes of MSW on daily basis, which is roughly 0.56kg/capita/per/day. Moreover, the study revealed that changes in municipal solid waste management policies have taken place over the past decades, and with the subsequent establishment of the Federal Environmental Protection Agency to supervise the regulations of the Environmental Act. These policies also brought about the implementation of privatization to reduce the problem of solid waste, recognizing the effects of MSW as a key challenge in Nigeria, the policy and plan strategy outline goals to be achieve, and this involve general waste collection, waste management, recycling, waste minimization, capacity building, education and awareness campaign as the major intervention. However, the major challenges hindering the effective MSW management is lack of policy implementation, poor funding, lack of trained waste workers and absence of efficient working tools among others. The study recommends the implementation of a well-equipped and control landfill under special supervision of waste management personnel to regulate the illegal activities in the sites. This review will help policy makers and decision makers involved in municipal solid waste management to understand the present issues, challenges and obstacles for efficient municipal solid waste management.
