A field experiment was conducted during 2010-2011 and 2011-2012 on deep black soil of Navsari, Gujarat to study the Phosphorus management in rabi Niger (Guizotia abyssinica L. Cass) – Fodder Sorghum (Sorghum bicolor L. Moench) cropping system. Application of 20 kg P2O5 ha-1 from SSP with PSM recorded significantly higher grain yield (628, 766 and 697 kg ha-1), total P uptake (4.51, 5.65 and 5.08 kg ha-1) by Niger and available P status of soil (50.11 and 49.44 kg ha-1) after harvest of niger than control (no phosphorus) during both the years and remained at par with application of 10 kg P2O5 ha-1 from SSP + PSM. Similarly, application of 10 kg P2O5 ha-1 from SSP + 100 kg RP ha-1 + PSM preceding fodder sorghum recorded significantly higher green fodder yield of sorghum (368, 415 & 391 q/ha), available P status of soil (43.37 and 44.19 kg/ha) after harvest of fodder sorghum and net realization from niger-fodder sorghum cropping system (5915 and 39,109 /ha) over other treatments during both the years. Thus, it is evident that with respect to the economy in fertilizer use, a saving of 25 per cent RDF (20 kg N + 10 kg P2O5 ha-1) in fodder sorghum can be achieved under adequately fertilized niger-fodder sorghum cropping system.

An investigation was carried out to assess the genetic parameters like variability, heritability and genetic advance, character association and path analysis for five yield component characters viz., plant height, number of productive tillers per plant, days to 50% flowering, days to maturity and grain yield per plot in 24 genotypes of Barnyard Millet (Echinochloa frumentacea ). The genotypic coefficients of variation for all the characters studied were lesser than the phenotypic coefficients of variation indicating the interaction of genotypes with environment. High heritability coupled with high genetic advance was observed for grain yield per plot indicating the importance of additive gene action in governing the inheritance of these traits. Hence, simple selection is effective to improve the respected trait. Association studies revealed that, four out of five characters exhibited highly significant positive correlation with grain yield per plot. However, the traits number of productive tillers per plant, days to 50% flowering, days to maturity were found to possess significant association in desirable direction with grain yield per plot at both genotypic and phenotypic levels. Path analysis studies revealed that number of productive tillers per plant, days to 50% flowering, days to maturity showed true relationship by establishing significant positive association and direct effect on grain yield per plant both at genotypic and phenotypic levels and plant height at genotypic level.

Coriander (Coriandrum sativum L.) is an important crop for its tender leaves with characteristic flavor used for culinary preparations as well as the seed used mainly in powder form as spice. Protected cultivation in summer days is a possible alternative to farmers to manage external climatic factors, which may affect seed’s germination and plant biomass of coriander. To find out the relationship between growth and development of coriander with microclimate, a study was conducted under open and protected conditions. Result showed a significant negative correlation between maximum temperature (Tmax) with green leaf yield after one cut (r= -0.823*), green leaf yield after two cut (r= -0.862*) and essential oil content of leaf in no cut (r= -0.829*). Besides, essential oil of leaf in one cut was found positively correlated with both maximum relative humidity (RH max) (r= 0.861*) and minimum relative humidity (RH min) (r= 0.431). Significant negative correlation was observed between Tmax and seed yield (r= -0.853*). Interestingly RHmin and seed essential oil was positively correlated (r=0.880**). No correlation was found between Tmax fluctuation and leaf yield. RHmax was positively correlated with green yield after one cut (r= 0.996**) and green yield after two cut (r= 0.962**).
