Hydropriming has the potential to ameliorate the stress-induced ill effects on yields of the crop plants and quality of seed produced. In the present study, half of the fresh seeds of maize hybrid, PEHM 5 and its parental lines (Female - CM 150, Male - CM 151) were subjected to accelerated aging test for bringing down the viability and vigour, thereby creating low vigour lots while high vigour lots consisted of fresh seeds, which were hydroprimed (30 h at 25°C). Half of the hydroprimed seeds were surface dried while the other half were redried back to the original moisture contents.

Small RNA (sRNA) sequences are known to have a broad impact on gene regulation by various mechanisms. Their performance for the prediction of hybrid traits has not yet been analyzed. Our objective was to analyze the relation of parental sRNA expression with the performance of their hybrids, to develop a sRNA-based prediction approach, and to compare it to more common SNP and mRNA transcript based predictions using a factorial mating scheme of a maize hybrid breeding program.

The treatments consisted of soil application of three nitrogen levels (100, 120, 140 kg/ha) and three Iron levels (10, 20, 30 kg/ha). There were 10 treatments each replicated thrice. The experiment was laid out in Randomized Block Design. Maximum result showed in growth parameters viz. plant height, Number of leaves per plant, Dry matter production, were recorded highest inT9 nitrogen 140 kg/ha + Fe 30 kg/ha and yield parameters viz. number of cobs per plant, number of grains per cob, test weight...

Maize is a heavy nutrient feeder crop but over and inappropriate fertilization provides lesser yield than the genetic yield potential, lower profits and deterioration in soil health therefore, a new fertilizer recommendation approach, Nutrient Expert (NE) for hybrid maize was evaluated against farmers fertilizer practice (FFP) in three years maize-wheat rotation. Results revealed that nutrient expert-decision support system based nutrient management gave higher yield, nutrient uptake and profits and sustained soil properties over other practices.

A study was carried out using 48single cross experimental maize hybrids developed from 16 lines (with high test weight and per se performance) and three testers crossed in Line × Tester design and were evaluated at three diverse environments, viz. Arabhavi (Northern dry zone), Agriculture Research Stations of Nippani and Main Agricultural Research Station (MARS) Dharwad (Northern transition zone) in Karnataka, for their grain yield stability.

In the present study SSR markers were shown to be polymorphic between parents which would help in establishing the genetic purity of hybrids in commercial seed lots. Also, few SSRs were found to discriminate among the set of hybrids which will ease the seed identity of competing hybrids in seed chain. Low probability of identity based on marker information suggests that a set of markers identified in present study can be efficiently used in establishing distinctness, identity and purity of hybrids in open markets after their release.

The experiment consisted of three levels of nitrogen (90,120 and 150 kg ha1 ) with basal application of P2O5 and K2O each at 60 kg ha-1 and zinc at 15kg ha-1 (basal application) or 0.5% ZnSO4 (foliar spray) and inoculated with Azotobacter or Azospirillum. Highest number of cobs plant-1 , plant height, dry weight, grains cob-1 and grain yield was recorded in the plots treated with 150 kg ha-1 N + 15 kg ZnSO4 basal along with seed inoculation with Azospirillum 20 g per kg seeds.

The experiment was carried out during Rabi 2012-13 and 2013-14 at Agricultural Research Station, Gangavathi to study the effect of SSNM practice by using nutrient expert on hybrid maize (GK-5029) under zero tillage in TBP command areas of Karnataka. The pooled data of two years revealed that among main plots there was no significant difference between mulch and without mulch treatments with respect to growth and yield parameters.

Pearlmillet (Pennisetum glaucum L.) is largely grown for grain and fodder purpose under those situations where other crops generally fail. Pearlmillet as a food crop is limited to the developing countries in Asia, and particularly in Africa and ranked sixth in the world followed by rice, wheat, maize, barley and sorghum (Anonymous, 2010-11).
