ABSTRACT

Sichuan province is extremely rich in Chinese herbal medicine resources,and the Chinese herbal medicine industry is an integral part of the "10+3" industrial system of modern agriculture. However,it has been long constrained by factors such as hilly terrain and scattered planting patterns,which hinders the mechanization development of the Chinese herbal medicine planting industry. Committed to promoting the application and development of the whole-process mechanization of Chinese herbal medicine production, the research group investigated the current situation and mechanization application of the Chinese herbal medicine planting industry in Sichuan province,and clarified the core advantages of the industry in Sichuan province and the urgent need for mechanization production. The current situation of mechanization of key links in producing rhizome-type Chinese herbal medicines such as planting,fertilization,pest and weed controlling,harvesting,and primary processing in production areas were analyzed. The key factors and existing problems in the whole-process mechanization development as well as the key future research directions were discussed,and the mechanization development trend of Ophiopogonis Radix,Chuanxiong Rhizoma and other herbal medicines in the Chinese herbal medicine planting areas of Chengdu Plain were forecasted. This paper focused on the bottleneck of the mechanization application in producing Chinese herbal medicines in Sichuan province,and introduced key technologies and equipment for the whole-process mechanization of rhizome-type Chinese herbal medicine production,which is conducive to transforming and upgrading the Chinese herbal medicine production industry,accelerating the application of high-tech information technology,and promoting the mechanization and intelligentization of the planting industry.

ABSTRACT

Cereal crops such as maize, wheat, sorghum and pearl millet are important for human consumption due to their nutritional benefits. These cereals play pivotal roles to meet world’s food demand. However, maintenance of food security particularly in the circumstance of changing climate, constantly urges for modification of agro-techniques and one such modification is the incorporation of transplanting technique in these cereals as an alternative under a non-practicable situation of direct sowing. Transplanting is a method of transferring seedlings grown in nursery or others to the field. It has been already found to shorten the crop duration and improve germination, plant stand, seed and seedling quality parameters, growth, yield and economic profitability of these cereals. Besides, research findings are also available stating that transplanting helps these cereals to cope up with vagaries of weather and to exhibit greater radiation and water use efficiencies and suppression of weeds. Outcomes of transplanting are however dependent on various factors like methods of nursery raising, the variety used, mode of planting, age of seedlings etc. In spite of these prospects, transplanting technique is not so popular in these cereals due to poor dissemination, discouraging research findings, pest and disease problems, lack of suitable package of practices etc. Therefore, focuses are to be given in conducting more and more research trials to confirm its location and situation wise efficacy and also in developing and disseminating a suitable package of practices of transplanting accordingly.

ABSTRACT

A field experiment was carried out at Agriculture Farm, Palli Siksha Bhavana, Visva-Bharati, Sriniketan, West Bengal, India during kharif season of 2015 to compare rice cultivation in conventional transplanting (CT) and system of rice intensification (SRI) in terms of energy use, energy input output relationship and green house gas emission. Results showed that regardless of cultivars, conventional transplanting consumed 62.39% higher energy over SRI. Maximum energy input was associated with non renewable and indirect sources. Higher dose of nitrogenous fertilizer had contributed to 32.35% and 26.26% to the total input energy in CT and SRI respectively. Energy use efficiency (13.22), energy productivity (6.94 kg MJ-1), energy profitability (12.22) and energy intensity (4.60 MJ Rs-1) of hybrid rice varieties were noted higher in SRI. Maximum green house gas emission from rice field was also attributed to fertilizer nitrogen followed by diesel in both the system. Total green house gas emission in CT was estimated to 834.85 (kg CO2ha-1) i.e. 1.8 times of SRI. Engirdling different energy indices, total input energy and green house gas emission, the system of rice intensification was emerged as the most energy efficient and sustainable rice production system in resource stricken areas (Red Lateritic Zone).

ABSTRACT

Objective: An efficient and stable regeneration system was developed to select the optimal protocol for plant regeneration with various explants of Gentiana rigescens. Methods: The study was designed as a L9(34) orthogonal experiment to explore the effects of different types and concentration of plant growth regulator combinations on adventitious shoot formation and plant regeneration, using different explants maintained on Murashige and Skoog (MS) medium after a single factor pre-experiment had been conducted. Results: Stem with buds was the optimal explant for indirect organogenesis with a frequency of callus induction of up to 97.73% obtained on MS + 6-BA 1.5 mg/L + NAA 1.0 mg/L + KT 0.05 mg/L after 10 dwith the axillary shoots starting to germinate along with the emergence of callus with a strong capacity of differentiation from the base; The callus started to generate green multiple shoots with a 100% rate after 15 d and a coefficient of differentiation in the clump shoot of 18.65. The multiplication coefficient was up to 63.58. However, the stem tip was the best explant for direct organogenesis with a propagation coefficient of up to 44.36 cultured on MS + 6-BA 0.5 mg/L + NAA 1.0 mg/L + KT 0.5 mg/L 30 days later. The plantlet derived from two explants was too weak for rooting and the weak multiplication plantlet was maintained on MS medium supplemented with 6-BA 1.5 mg/L, NAA 1.0 mg/L, KT 0.05 mg/L, and PP333 10 mg/L to rejuvenation for 60 d. The regeneration plant with 100% rooting rate was obtained by culturing on 1/2 MS + 6-BA 0.1 mg/L + NAA 2.0 mg/L for 45 d and more than 95% of plantlets survived after transplanting. Conclusion: The current study established a rapid propagation system which is helpful to protect the wild resources and high quality seedling propagation of G. rigescens, meanwhile providing scientific evidence for the research on genetic transformation.

ABSTRACT

Mechanization in agricultural sector is advancing in developing countries like India. Rice is a labour-intensive crop and requires about 80-90 labour days per acre. Timely availability of labour and water for various activities of rice is becoming a problem. The cost of the labor among the cultivation cost also increased from 15-18 % to 45-47% during the last decade. Water scarcity is also increasing due to climate variability in the country. Hence, to overcome labour shortage and sustain rice production with less water, the recent phenomenon observed in Andhra Pradesh state is the use of machine transplanters and harvesters. These are resulting in the process of mechanization and increasing their popularity during the recent years. The machinery transplantation was taken up in 21 farmers fields covering 0.4 ha each. The field observations from the farmers’ fields show that machinery transplantation reduces seed by 50 % and labour by 22%. The nursery cost for the machinery transplantation is higher compared to traditional transplantation method (by Rs 2330). The other major observations noticed during the validation of technology was, that number of hills per sq.m and tillers in a hill are higher compared to the manual transplantation, resist lodging during heavy floods. The effective tillers in a hill range from 12-15 and also increase the panicle grain number. The yield of rice was found to be higher by 6-7 q/ha compared to the manual transplanting. The total variable cost with the machine transplantation does not show any significant difference with the transplantation method. Government is also promoting machine transplanters through subsidized policy to the farming community. However, relevant capacity building programs on the mat nursery preparation for machine transplanting is lacking.

ABSTRACT

O trabalho foi conduzido em ambiente protegido, UNESP-Fazenda Experimental São Manuel da Faculdade de Ciências Agronômicas -Botucatu no município de São Manuel-SP no solo classificado como Latossolo Vermelho Amarelo fase arenosa. Determinou-se o estádio de desenvolvimento da muda para o transplante, com cinco a seis folhas definitivas, em estádio de plena floração e em início da frutificação. O tomateiro (Lycopersicon esculentum Mill), híbrido Momotaro T-93, foi cultivado sobre dois porta-enxertos, os híbridos Anchor T e Kaguemusha e em pé franco. Avaliou-se área foliar, comprimento e massa seca das mudas no momento do transplante; número de folhas total/planta; massa fresca e seca das folhas abaixo do terceiro cacho floral e classificação dos frutos em diâmetro e produção total até o 8º cacho. Conclui-se que o estádio de desenvolvimento de mudas de pé franco, transplantadas com 5 a 6 folhas definitivas, é o que apresenta as maiores médias para produção e diâmetro médio de frutos. Para mudas enxertadas, o estádio de cinco a seis folhas definitivas até plena floração, não houve diferença na produtividade e qualidade final, sendo os melhores desempenhos obtidos pelo porta-enxerto Anchor T.
