Four cultivars of tuberose (Polianthes tuberosa Linn.), viz. Kalyani Single, Kalyani Double, Suvasini and Prajwal were used to study the mutagenic effectiveness of various physical and chemical mutagens viz. Gamma rays, X-rays and EMS, by treating the healthy and uniform bulbs of tuberose with different doses each of gamma rays viz., (5, 15 Gy), X-rays (6, 12 Gy) and EMS (0.1, 0.2%) along with the untreated bulbs as control and evaluated for various vegetative and floral characters. The findings of the experiment showed that the treatments of the mutagens at lower doses had significant simulative effect on vegetative parameters viz., sprouting percentage, days to sprouting while the parameter pertaining to survival rate, leaf length, number of spikes per plant, florets per spike, flowering duration and vase life were observed with decreasing trend. Higher doses of all mutagens had detrimental effects on the vegetative and floral characters. Mutants exhibited variation from the parent plant with respect to the vegetative characters.

Krishi Vigyan Kendra (the Farm Science Centre) is a noble concept developed by Indian Council of Agricultural Research (ICAR), which rests upon a solid base of transfer of technology from laboratory to farmer's field with respect to Agriculture, Horticulture, Animal husbandry, Floriculture. Bee keeping, Mushroom Cultivation, Broiler Farming and allied subjects. The present study was undertaken to assess the adoption level of beneficiaries and non-beneficiaries of KVKs working in the tribal district of Madhya Pradesh. The study was conducted with 300 tribal farmers i.e., 225 beneficiaries and 75 non-beneficiaries randomly selected in 12 villages of Mandla, Dindori and Shahdol district, which were results showed that. Tribal farmers were of comparatively middle age group, education up to high school, agriculture + other as their occupation, medium annual income, medium landholdings, medium experience, high attitude towards technological demonstration, high knowledge about KVK activities, high perception towards scientific agriculture, medium market orientation, high scientific orientation, high aspiration level, medium use of information sources and high training exposure. The adoption level of tribal farmers was high.

The present study analyses the total yield gap in Rice crop into three different gaps viz. yield gap-I, yield gap-II and total yield gap. The study was conducted in Mirzapur District using primary data collected from 60 sample farmers covering four sample Blocks for the year 2097- 2010. In order to evaluate the objectives of the study, a multistage stratified random sampling technique was adopted Most of the sample farmers were growing vatimansuri variety of rice crop. Yield gap analysis shows that 23 per cent yield gap was estimated between potential and potential farm yield where as yield gap between potential farm yield and actual yield was estimated 23.12 percent. Index of realized potential farm yield was observed 75.20 percent on marginal farms to 80 percent on large farms with an overall average of 76.0 percent. The main causing factors of yield gaps was due to variation in the quantum of resource used and proper timing of the resources use.

Commiphora wightii (Arnott.) Bhandari is found in the semi arid and arid regions of India. Over exploitation of this species for its Oleoresin has led to its decline in their natural stand. During the guggul tapping season in the year 2013-14, the abiotic stress was less in comparison to that in the year 2012-13. Less abiotic stress due to winter rain on the guggul production in Chambal ravines. The mean production of guggul gum during the year 2012-13 was 385.30 g, while it was 145.59 g during 2013-14. Thus the mean gum production per plant declined by 62.61 percent during 2013-14, besides this the viscosity of the guggul gum was affected due to winter rain during 2013-14. Those plants tapped before rains produced comparatively more gum, similarly the proportion of tapped trees damaged was higher than those with untapped trees during the year. Gum production was positively correlated with temperature while rainfall was negatively correlated with other variables during both the year. Tapping of Guggul in ravines is carried out from last week of February to March, was delayed by one week during 2013-14. The delay was due to low temperature and high humidity during the tapping period.

Field trials were conducted at Agricultural Research Station, Kawadimattii, during kharif 2010-11 and 2011-12 to evaluate the efficacy of new anthranilic diamide, Cyantraniliprole (Cyazypyr) (HGW 86) 10.26 % OD at different dosages for the management of insect pests of brinjal (Solanum melongenaL.). The standard insecticides viz., Chlorantranilprole 18.5% SC, Spinosad 45% SC and Imidacloprid 17.8% SL were used for comparison. Overall, the field trials revealed that, Cyantraniliprole 10.26 %w/w OD @ 90 g a.i/ha provided cross-spectrum control of insect pests as it registered lowest number of hoppers (0.26/leaf), whitefly (0.40/leaf), thrips (5.16/leaf) at 10 days after application and also recorded lowest percent fruit damage by shoot and fruit borer (1.09%) and highest yield of 49.70 t/ha during season I. Whereas the standards, Chlorantranilprole, Spinosad and Imidacloprid recorded a yield of 42.17, 42.28 and 23.86 t/ha, respectively. The same trend was noticed during season II (2011-12). The studies indicated that Cyantraniliprole 10.26 %w/w OD @ 90 g a.i./ha can be recommended in an Integrated Pest Management Program (IPM) of brinjal for the management of insect pests and harnessing higher yield.
