Nitrogen is a major essential yield limiting nutrient in crop production, it serves as a constituent of many plant cell components, such as amino acids and nucleic acids. Hence it is important to improve the productivity as maize is an exhaustive crop. The low productivity of maize during kharif season is attributed to a wide range of constraints including the low nitrogen use efficiency.

A field experiment was conducted at Research Farm, Department of Agronomy; Jawaharlal Nehru Krishi VishwaVidyalaya Jabalpur during 2012 consisting of seven newly developed maize hybrids and one composite variety for yield parameters in rainfed condition. The results of present study revealed that, the yield attributing parameters viz., number of cobs/ plant, grain rows /cob, number of grain /row, total grain /cob, cob weight and seed index were found significantly highest in hybrid Proagro Ly 620 as compared to most of the hybrids.

Combining ability was studied in a 4 × 4 half diallel cross in maize for grain yield and yield contributing characters under arsenic treatment. Half diallel analysis is an efficient method for the study of combining ability and the gene action of the characters under study. Combining ability (GCA and SCA) refers to the ability of a genotype to transmit superior performance to its crosses.

Farmers‟ participatory demonstrations on jute cultivation using zero tillage (ZT) technology were conducted in West Bengal through standardized conservation agriculture (CA)-jute protocols developed jointly by Uttar Banga Krishi Viswavidyalaya and International Maize and Wheat Improvement Centre (CIMMYT). The results of demonstration indicated a significant yield increase under ZT over conventional practices.On an average, an yield increase of 25.83-27.83% under zero tillage technology reflected the positive effect of demonstration over the existing practices.

A field experiment was carried out during the rabi season of 2011-12 and 2012-13 at Bihar Agricultural University, Sabour (Bihar) to assess the effect of integrated weed management practices on weed dynamics, productivity and nutrient uptake of maize (Zea mays L.). Results revealed that weed management practices had positive influence on growth, yield attributes, yields and nutrient uptake of maize. Significantly lower weed density, weed dry weight and weed control efficiency (WCE %) were recorded in zero tillage (ZT) compared with conventional tillage (CT).

The efficiency of a breeding programme depends mainly on the direction and magnitude of the association between yield and its components and also the relative importance of each factor involved in contributing to grain yield. The path analysis provides an effective measure of direct and indirect causes of association and depicts the relative importance of each factor involved in contributing to the final product.
