Rice root-knot nematode, Meloidogyne graminicola cause considerable yield loss in rice-wheat cropping system due to which it gained a wide importance in the world. An experiment was undertaken on the infested pot, soil to evaluate the effectiveness of temperature with different time of sowing on infestation of root knot nematode in the wheat crop. This experiment was conducted from mid October 2014-mid January 2015 and wheat seed were sown at 15 day intervals. The temperature range was determined from minimum 7.060C to maximum 30.120C during the experiment. The infestation of root knot nematode was found only in early three sowing (mid October–mid November). The highest infestation of root knot nematode (Av. 24.33 galls/ plant) was observed in wheat crop, which was sown at 15/10/14 followed by 7.67 and 3.17 galls/plant at 01/11/14 and 15/11/14 date of sowing respectively and significantly decrease root length. In another four sowing time (1st December- 15 January), the infestation of root knot nematode was not observed and significantly increase the root length. The present study revealed that sowing of wheat after the first week of December in western Uttar Pradesh reduces the infestation of root knot nematode.

The study was conducted in Jashpur district of Chhattisgarh state. Knowledge of the tomato production technology is important for increasing the production level. Hence, this study was conducted to know the knowledge level and its relationship with personal and socio-economical characteristics of tomato grower. The study revealed that tomato growers with medium level knowledge of tomato production technology having detailed knowledge about important tomato production technology. The study also revealed that age, education, caste, land holding, type of family, housing pattern, occupation, social participation annual income, extension contact, material possession, innovativeness, economic motivation, risk orientation, scientific orientation and adoption were positivity associated with significant knowledge of recommended tomato production technology.

Rapid increases population enhance the demand of water and affect land use change that is land degradation, soil erosion, so for Present study was conducted Jabalpur district of M.P., During 2014-15, total 200 farmers were selected for the study and the main objective of the paper was to know socio economic character sticks and there relation with income, Result shows that age has non-significant relationship and other 9 variable that is education, occupation, size of land holding, risk preference, economic motivation, scientific orientation, knowledge, adoption and attitude towards watershed development found to be positively significant with 4 degree of freedom. It is very important to know impact of watershed management practices to know the relationship with socio economic profile of the beneficiaries.

Black gram (Vigna mungo L.) has the potential of supplying a major portion of dietary protein demand and restoring the soil health at the same time. Research on genetic variability studies of the genotypes may increase the opportunity to exploit its potential which will help to meet the demand of high yield and nutrition supply. In this connection, an experiment was conducted to estimate the genetic variability of quantitative and qualitative traits in 24 lines of black gram. Genetic parameters like genotypic and phenotypic variance, coefficient of variation, heritability and genetic advance were estimated. Except for days to maturity a significant variation was noted for all the traits. The genotypes were highly variable for cluster plant-1, pods plant-1, seeds pod-1 and seed yield plant-1. In general phenotypic coefficient of variability was greater than their corresponding genotypic coefficient of variability. Broad-sense heritability was higher for all the traits except for days to 50 per cent flowering and branches plant-1. High heritability coupled with high GAM was observed for the characters pods cluster-1, pod length, test weight, seeds pod-1 and seed yield plant-1 indicating that these characters are mainly controlled by additive genes and selection of such traits might be effective for the improvement of grain yield. The genotypes with dull seed luster were highly frequent than shiny seed luster. Globular seeds producing genotypes were more frequent than those producing drum shaped and globular seeds.

The experiment was laid out in Randomized Block Design with ten treatments viz., T1 (Control), T2 (GA3 10 ppm), T3 (GA3 20 ppm), T4 (GA3 30 ppm), T5 (NAA 25 ppm), T6 (NAA 50 ppm), T7 (NAA 75 ppm), T8 (TIBA 10 ppm), T9 (TIBA 15 ppm) and T10 (TIBA 20 ppm). The results revealed that, the maximum length of main creeper at 60 and 90 DAS (201.78 and 309.23 cm), respectively, number of sub-creeper at 60 and 90 DAS (7.53 and 8.23) and number of leaves/plant at 60 and 90 days after sowing (244.10 and 412.68), maximum chlorophyll content at 45 and 60 days (31.38 and 36.85) and produced the maximum number of male flower (165.75) were recorded with treatment GA3 30 ppm (T4). The TIBA 20 ppm (T10) proved to be most effective for producing the lower node number at which first female flower appears (8.25), maximum number of female flower (19.35) and lowered sex ratio (1: 7.13) and maximum number of fruits (3.00), fruit yield/plant (12.39 kg), fruit yield/ha (619.50 q/ha) and fruit length (24.32 cm). The maximum average fruit weight (4.27 kg/fruit) and fruit diameter (22.71 cm) recorded in treatment T9 (TIBA 15 ppm).
