The study is very necessary not only for understanding the growth trends and magnitude of fluctuations in crop production but are also useful for scientific planning and effective implementation of agricultural developmental at different levels. The necessary secondary data were collected for a period of 34 years from 1979-80 to 2012-13, which divided into three groups i.e. Period-I (1979-80 to 1986-87), Period-II (1987-88 to 1997-98) and Period-III (1998-99 to 2012-13). Three models linear, quadratic and exponential have been used for the study of trend analysis of the Pigeonpea for the three districts (Sarguja, Koriya and Jashpur) of Northern Hills of Chhattisgarh in India. Compound Growth Rate (%), Coefficient of Variation (%) and Instability Index have been calculated for the respective periods and all three models. Growth rates showed a significant positive growth in area under Jashpur and Koriya while Sarguja showed non-significant negative growth. Similarly, the production of pigeonpea showed a significant positive growth for Sarguja and Jashpur whereas Koriya registered insignificant positive growth. The productivity of this crop recorded negative non-significant growth in the case of Sarguja and Jashpur while Koriya recorded positive significant growth. Study showed moderate variability in area, production and productivity. The instability indices for the area, production and productivity for pigeonpea crop were positive and less and thereby indicating medium risk for growing this crop in coming days.

Aims: The study was to estimate and characterise the existing genetic variability of new candidate imported sugarcane varieties under Northern agro-climatic conditions of Côte d'Ivoire.

Study Design: A randomised complete block design with nine genotypes (clones) and four replications was used. The clones were planted in sandy-clay soil over an area of 95.68 m2. Each clone was planted in a single row of 10 meters and in 6 rows with 1.5 m between rows (10 m x 6 x 1.5 m).

Place and Duration of Study: During 2014 and 2016 crop seasons, performance of seven new imported sugarcane clones with different origin were obtained from CIRAD Montpellier tested with two control varieties SP701006 and R579.

Methodology: Germination rate, plant height and tiller number per stool, individual stalk weight, tons of cane per hectare (TCH, t ha-1) was determined and Pol% C was measured using a saccharimeter. The sucrose yield (TSH) was then calculated. At harvest, the rate of internodes attacked by Eldana saccharina was determined.

Results: Genotypes significantly differed for all the 6 traits indicating sufficient variability in the experimental material. The phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) for all traits studied, indicating that the apparent variation was not only genetic but also was influenced by the growing environment in the expression of the traits. In general, the quantitative trait was highly influenced by the environment. The GCV values were a bit lower ranging from 2.03% to 26.40% while the PCV values ranged from 3.21% to 53.70%. The traits TSH and Fiber showed high GCV and PCV. In the current study, the heritability ranged from 8.65% to 83.86%, while genetic advance as a percentage of the mean showed a wider gain ranging from 6.50% to 33.85%.

Conclusion: High estimates of heritability with high genetic advance were observed for TSH followed by Fiber, %Pol. Therefore, selection will be effective for these characters.

Land resource inventorisation is a method to assess the available natural resources for effective utilisation. To characterise and classify the soils at large scale (1:7920 scale), this study was carried out in Gollarahatti-2 micro-watershed located in Jagalur taluk of Davanagere district, Karnataka, India. Based on the landform and physiographic units the Gollarahatti-2 micro-watershed soils were categorised into eleven soil series and twenty- two soil phases and mapping units, and all the typifying soil pedons representing the study area were sampled. Morphological, physical, chemical and physico-chemical properties of the identified soils were characterised under field and laboratory conditions, and the soils were classified into the family level as per the USDA soil taxonomy. The soils were varied in depth from very shallow (<25cm) to deep (100-150cm), reddish brown (5 YR4/4 to very husky red (2.5YR2.5/2), slightly acidic to alkaline and non-saline. The texture of the soil was varied into sandy clay, clay loam and clay. The organic carbon ranged between low (<0.5%) to medium (0.5-0.75%). Further, the soils have high base saturation (>60%). Pedon 11 had higher exchangeable sodium percentages (>8%) in subsoil layers. The differentiated soils were grouped under 11 soil series mapped into 22 mapping units and classified into Lithic Ustorthents, Typic Haplustepts, Typic Rhodustalfs, Kanhaplic Rhodustalfs and Rhodic Kanhaplustalfs at subgroup level as per the USDA soil taxonomy.

Climate change is being considered as a serious threat to the livelihood of Indian farmers. Depleting groundwater table is one of the consequences of climate change. Practicing water saving technologies at the farm and household level can mitigate the effects of climate change. Thus, to study the gender-based knowledge disparities of the farming community regarding water saving technologies at the farm and household level, the present research was conducted in three villages each from three water zones of Punjab namely north-east, central and south-west zone. A sample of 240 respondents was randomly selected with equal representation from each zone. Pre and post knowledge test was administered to measure the knowledge level of the farming community. The findings revealed that most of the respondents belonged to the general category, were middle-aged, studied till matriculation, had a joint family system and family size in the range of 2-6 members. Furthermore the findings revealed that the knowledge of most of the farmers and farm women regarding water saving technologies was low to medium level, but after intervention, the knowledge level of most of the respondents increased to high to medium level. The study concluded that although the knowledge level of the farming community regarding water saving technology was low to medium yet, it can be increased by imparting knowledge through various communication strategies. Thus the extension workers should make efforts to work on different communication strategies to increase the knowledge level of the farming community so that they can be capacitated to mitigate the effects of climate change.

Heart of oil palm tree (Elaeis guineensis Jacq.), little known, is a vegetable consumed after boiling. This study is an evaluation of the impact of boiling times (15, 30, 45 min) on physicochemical and nutritive composition of this vegetable. Moisture, fiber and carbohydrate contents differ significantly (p<0.05) and increased in all three parts (PP, MP, DP) during boiling times. Moisture contents (%) varied from 89.94±0.08 (PP0) to 92.23±0.15 (PP45), 88.13±0.27 (MP0) to 89.75±0.97 (MP45) and 91.38±0.5 (DP0) to 92.08±1.49 (DP45). Fibers contents (%) varied from 26.49±0.13 (PP0) to 32.26±6,89 (PP45), 34.90±0.01(MP0) to 37.67±1.12 (MP45) and 21.9±0.02 (DP0) to 29.41±2.63 (DP45), Carbohydrates contents (%) varied from 39.85±0.47 (PP0) to 47.05±3.61 (PP45); 39.91±1.15 (MP0) to 45.47 (MP45); 46.37±1.97(DP0) to 59.55±1.26 (DP45). Ash, protein, and fat contents differed significantly (p<0.05) and decreased in all three parts (PP, MP, DP) during cooking times. Ash content (%) ranged between 8.28±0.51 (PP0) to 5.48±1.85 (PP45), 6.91±0.07 (MP0) to 4.58±1.48 (MP45); 8.00±0.06 (DP0) to 5.51±0.25 (DP45). Protein contents (%) ranged between 12.56±0.65 (PP0) to 7.38±1.3 (PP45), 10.70±0.06 (MP0) to 9.72±0.65 (MP45), 13.12±0.69 (DP0) to 4.47±0.67 (DP45). Fat contents (%) ranged between 12.81±0.59 (PP0) to 7.58±0.98 (PP45), 7.57±0.8 (MP0) to 2.56±0.42 (MP45); 10.61±1.13(DP0) to 1.06±0.05 (DP45). Boiling times significantly (p <0.05) reduced contents of flavonoids, tannins, polyphenols, phytats and oxalats. Significant correlations were observed between moisture and fiber parameters, protein and ash, oxalates and flavonoids, oxalates and phytates.
