Yield And Quality

As the northern hemisphere will experience the greatest increases in temperature and indications of climatic change are already visible in the north (in the 2000s average temperatures exceeded the long-term mean), we sought to establish if there are already signs of increased variability in yield and quality of the major field crops grown under the northernmost European growing conditions: spring and winter cereals (barley Hordeum vulgare L., oat Avena sativa L., wheat Triticum aestivum L., rye Secale cereale L.), spring rapeseed (turnip rape Brassica rapa L., oilseed rape B. napus L.), pea (Pisum sativum L.) and potato (Solanum tuberosum L.). We used long-term yield datasets of FAO for Finland (1960s to date) and MTT Agrifood Research Finland (MTT) Official Variety Trial datasets on yield and quality of major field crops in Finland since the 1970s. Yield variability was exceptionally high in the 1980s and 1990s, but previously and subsequently national yields were clearly more stable. No progressive increase in yield variability was recorded. No marked and systematic changes in variability of quality traits were recorded, except for rapeseed, which exhibited reduced variability in seed chlorophyll content. This may at least partly attribute to the differences in intensity of input use and thereby responsiveness of the crops before and after 1980 and 1990 decades. We also noted that in the 2000s average temperatures were higher than in earlier decades and this was the case for all months of the growing season except June, which represents, however, the most critical phase for yield determination in most of the field crops in Finland. Also in the 2000s precipitation increased in the first three months of the growing season and thereafter decreased, but without signs of significantly increased numbers of heavy showers (extreme rain events). Hence, in general constant, increased average temperatures during the growing seasons of the 2000s were identified, but with reduced yield variability, which was partly attributable to the diminished use of inputs, especially fertilisers.;

Agriculture plays a vital role in Indian economy, contributes 13% of gross domestic product and provides employment opportunities to more than 50% of work force.  In India 60% of land area are arable leads to second largest country in terms of total arable land area. The technology development rate is 2 percent and farm productivity rate only increase by 0.3 percent in major crops. It implied that outreach of technology from lab to land have several constraints. In this study, yields gaps of major field crops are calculated with the data provided by the joint directorate of Tamil Nadu, to find, to which extent the advancement in agriculture is helpful and it is found out that the yield gap II of selected varieties of major crops are high. It shows the deviation from the potential yield of the variety with the actual yield obtained by the farmer.

Seed Supply

The seed replacement rate of major field crops is very low, about 8%, in Nepal with 92% seed supply of major field crops from informal sector. Different seed production initiatives are undertaken by public and private sectors. However, their role and effectiveness on seed sector development have not been assessed. A review on secondary data related to seed production and usage and primary data collected from different public and private organizations in the year 2011were used to assess the role of District Level Seed Self Sufficiency Program and Community Based Seed Production program on current seed supply situation in Nepal. DISSPRO is the most popular, widely adopted and cheapest seed producing program with annual production of 40.4% followed by CBSP 3.83% of the total certified/improved seeds in the country. The seed production trend of DISSPRO and CBSP is rapidly increasing. Strengthening seed sector through the integration of DISSPRO, CBSP and other seed initiatives together with effective enforcement of seed regulation for quality seed multiplication, distribution and use is necessary for rapid rise on SRR, enhancing crop production and food security in Nepal.
