The front line demonstrations on rice crop conducted by Krishi Vigyan Kendra, Badgaon, Balaghat during the last two years 2017 to 2018. The study was conducted to compare the farmer's practices of application of nitrogen fertilizer with N fertilizer application as per leaf colour chart. The N fertilizer application as leaf colour chart recorded superior in growth and yield traits as compared to farmer's practices. The grain yield was recorded 53.15 q/ha and net income and Benefit: Cost ration recorded Rs. 43597/-per ha and 1:2.01 on pooled basis in N application as per LCC. The N save over farmer practices was recorded 25.50 per cent. Leaf colour chart is tool that can help farmers improve their decision-making process in nitrogen management.

Data revealed that variances due Lines and Testers and Line X Tester were significant for grain yield and almost all attributes, thereby, showing these were under the control of both additive and non-additive inheritance. Additive variances governed the days to heading and days to maturity. Whereas, only first inter-node length governed by non-additive inheritance. Lines ‘WH-1062’ was good general combiner for days to heading, days to flowering, days to maturity, plant height, length of spike, grain per spike and test weight. ‘HI-8696 (d)’ was good general combiner for days to heading, grain filling period, plant height, second-inter-nodes length, flag leaf area, spike length, peduncle length and test weight. Tester viz., 43 rd IBWSN-1043, 43 rd IBWSN-1157 and 18 en HRWYT-227 identified as good general combiners for grain yiel...

Thirty-one genotypes consisting 7 lines, 3 testers and 21 crosses were studied for genetic and combining ability analysis in Line X Tester mating design. An experiment was conducted in randomized block design with two replications. Grain yield and 1000 grain weight were under the control of both additive and non-additive inheritance. However, Additive variances were higher than non-additive variance components. Among parents, GW 173, DL 803-3 and GW 190 showed significant positive general combining ability effects. MACS 6222 X PBW 343 recorded significant specific combining ability for 1000 grain weight. PBW 175 X PBW 343, DL803-3 X PBW 343, GW 322 X HD 2932, C 306 X HD 2932, GW 173 X GW 190 and HI 1544 X GW 190 crosses were significant and positive specific combining ability effects for grain yield. Thus present study revealed that GW 173, DL 803-3 and GW 190 may be use...

In order to evaluate drought tolerance in bread wheat varieties, an experiment was conducted with 125 promising genotypes in randomized block design with two replications each in no-stress and stress environments. Post-anthesis stress was created after 14 days after anthesis. Different drought tolerance indices viz., stress susceptibility index, relative drought index, mean productivity, stress tolerance index, geometric mean productivity, yield index, yield stability index, drought resistance index were evaluated based on grain yield under stress and non-stress conditions. Thirty-one varieties recorded significantly higher grain yield under stress environments along with significant favourable most of the drought indices viz., SSI, RDI, MP, STI, YI, YSI and DRI. Only 2 genotypes, 31ESWYT-147 and C-306 produced significantly high grain yield in both stress and non-stress conditions. Further, 31ESWYT-147 also showed significant favourable values of all drought tolerance indices except GMP, whereas, C-306 showed significant favorable values only for MP, STI, YI and DRI, respectively. STI and MP showed mostly positive and meaningful genotypic and phenotypic correlation with yield in both stress and non-stress environments and with other drought tolerance indices. Thus application of both indices could be appropriate while screening the varieties for drought tolerance. However, according to both STI and MP indices, promising genotypes varied differentially for drought tolerance. MP index leads the selection towards more efficient genotypes in both stress and nonstress environment. Thus screening for drought tolerances could be made either one or both of these two indices would be more effective in bread wheat. Drought indices had low heritability and genetic gain which were comparable to yield in stress but higher than yield in non-stress condition. Hence the improvement for yield potential under drought could be achieved through direct selection in stress or screening through STI and MP indices.

At global level, it ranks fifth in terms of area and production under legumes. It is grown with less care and low manorial requirement. The productivity of pea is low because of its cultivation generally in poor soils. Pulses have inherent capacity to fix atmospheric nitrogen in symbiotic association with Rhizobium. This characteristic of pulses has helped in maintaining the sustainable fertility levels of soils. Under the pulses the soil does not allow water to run very fast which enhance the soil productivity, especially in case of the dry farming zones. Because of their better ground coverage, the pulses reduce water losses through evaporation from the soil surface. Application of phosphorus increased the production of pulse crops (Sharma et.al 2014). The response of phosphorus depends upon many factors like climate, variety and soil type and availability of nutrient...

The minimum population of narrow and broad leaf weed species were recorded with hand weeding twice at 45 days stages, which was significantly highest weed control of treatments imazethapyr + imezamox (RM) @ 80 g/ ha PoE and pendimethalin + imazethapyr (RM) @ 1000 g/ ha PE at harvest stage. The maximum value of plant height, number of leaves and number of branches per plant; and yield characters number of pods/plant and number of seeds per pod parameters were recorded with Imazethapyr + Imazamox (RM) @ 80g / ha PoE, which was at par with two hand weeding at 20 and 40 DAS. It was followed by Pendimethalin + imazethapyr (RM) @ 750 g a. i./ ha PE. Weed free treatment provided the highest grain yield, gross returns and net re...

These crops are grown under a wide range of agroclimatic conditions. Among the edible oilseeds crops, Rapeseed & mustard occupies an important position in Indian oilseeds scenario. Indian mustard is the most important member of the group, accounting for more than 70% of the area under rapeseed-mustard, followed by toria, yellow sarson and brown sarson. Rapeseed and mustard are the third most important edible oilseed crops of the world after soybean and oil palm. Due to the gap between domestic availability and actual consumption of edible oils, India has to resort to import of edible oils. Rapeseed-mustard is the major source of income especially even to the marginal and small farmers in rain-fed areas. Since these crops are cultivated m...

Tester viz., 43 rd IBWSN-1043, 43 rd IBWSN-1157 and 18 en HRWYT-227 identified as good general combiners for grain yield and most of the attributes including harvest index. The cross, VL-920 X 18 en HRWYT-227 and VL-920 X 18SE SAWYT-303 was good specific combiner for grain yield and various yield components. These parents may be used for varietal improvement through the simple / recurrent selection in segregating generations to increase in yield potential of wheat. This may lead in the fixation of both additive and non-additive components while making improvement in grain yield and its attributes.
