An attempt has been made to predict the future yield of rice in plane region of Chhattisgarh using Decision Support System for Agrotechnology Transfer (DSSAT v 4.5) model. Raipur stations were selected and the DSSAT output of these stations up to Average 2080 was used in the model. Management combinations simulated were three sowing dates (D1-11th June, D2-21th June and D3-29th June 2011) and (D1-10th June, D2-15th June and D3-22th June 2012) for kharif rice cv. Karma masuri under rain fed and irrigation condition. Thirty three year (1981-2012) weather data (Max T, Min T, Rainfall and Radiation) was collected from Department of Agrometeorology, I.G.K.V., Raipur. First, the DSSAT v 4.5 model was calibrated and validated for locally popular medium duration varieties of kharif season (2011 &2012) Rice, namely, karma Masuri. The result showed that the early and late sowing dates gave lower yield as compared to optimum sowing dates. The decrement in the yield of rice in early sowing (1st week of July) dates and late sowing (last week of July) may probably be attributed to the increasing temperature in the future. The weighted yield was observed more than actual yield in central Chhattisgarh.

Orchids with their rich diversity of colours and forms coupled with long lasting characteristics occupy prime position in cut flower industry. Major problem with orchid production is its slow growth rate and slow vegetative propagation due to which there is always a shortage of elite planting material. Chitosan application has shown to increase yields and promote growth of some agricultural crops including orchids. The present experiment was conducted at climate controlled greenhouse at State Govt. Horticulture Nursery, Raipur, managed by Department of Horticulture, Indira Gandhi Krishi Vishwa Vidyalaya, Raipur during 2010-11 to study the effect of chitosan spray on vegetative growth and sprouting of Dendrobium 'Sonia-17' pseudobulbs.The experiment was laid in completely randomized block design with 25 treatments and four replications. The treatment combinations consisted of two different formulations of chitosan (CPl and CP2) at four different concentrations (C1-2.5 ppm, C 2-5 ppm, C3-7.5 ppm and C4-10 ppm) and number of applications (A1-One spray, A2-Two sprays and A 3-Three sprays). The results revealed that chitosan application had a significant effect on various vegetative growth parameters of Dendrobium "Sonia-17" pseudobulbs. The sprouting per cent ranged from 61.50 (control) to 100 in T13, T14 T15 and T 16 Maximum number of new shoots per pseudobulb was recorded on T 14 (2.5), it was followed by T15(2.25) and T13 (2.00). Longest shoot was recorded on T4 (28.37 cm) followed by T1, T11, T14 T17 T19 T20T21 T22 and T23. which were statistically at par with each other. Number of leaves, leaf width and length were also significantly affected by chitosan application. Maximum number of leaves was observed on T1 (5.75). Maximum leaf width was observed on T16 (3.63 cm), this was followed by T12, this treatment also recorded maximum length (11.5 cm) of leaf. Thus, chitosan spray was found to be beneficial for vegetative propagation and growth promotion of Dendrobium "Sonia-17".

The present study aimed to find out the crop water and irrigation water requirement for mustard crop over three locations of Chhattisgarh state to represent three agro climatic zones. Results revealed that highest crop water requirement (373 mm) and irrigation requirement (333 mm) is noticed at Raipur which is representing the Chhattisgarh Plain zone and lowest at Ambikapur (328 mm and 283 mm) of Northern Hill zone. Stage-wise information of irrigation water requirement for mustard crop would help judicious utilisation of available water and may reduce the over utilisation of ground water source.

The initial and conditional probability of rainfall, i. e. probability of wet P(W) and conditional probability like P (W/W) at 10 mm, 20 mm and 50 mm per week was worked out for the four districts of Chhattisgarh (Raipur, Bilaspur, Jagdalpur and Ambikapur) and results are interpreted. There are locational variations of getting wet week. In later part of the monsoonal season which is coinciding with the end of September, the probability of getting a wet week is very less in all the locations which are indicating the uncertain factor of rainfall in rainfed rice production. This is indicating the importance of medium range weather forecast and operational management for different crops grown in the state. This is only one technique and integrated therapy and techniques are the need of hour to make a balance with the ever-increasing need of food production. Further stress has been made to conserve surplus monsoonal rainfall in On Farm Reservoirs (OFR's) as rainfall is occurring in intense storms and utilize this rainwater for sustainable crop production and also for enhancing cropping intensity. The high potential of OFR's and other harvesting structures in alleviating drought, increasing productivity and stability of rainfed rice lands has been tested in this region for meeting this challenge of rainfed rice production. © EM International.
