The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.

The present study on Performance evaluation of Sweetcorn with different levels of Irrigation and nitrogen through drip during post monsoon season at Rajendranagar, Hyderabad, India was conducted for two years at Maize Research Centre, Agricultural Research Institute (ARI), Rajendranagar, Hyderabad to assess the influence of different levels of irrigation and nitrogen on performance of sweetcorn hybrid. Randomized block design with factorial concept was used in the study and the experiment was replicated thrice. The treatments used were two factors. Factor I was five irrigation levels viz., I1: Drip irrigation at 60% E pan, I2: Drip irrigation at 80% E pan, I3: Drip irrigation at 100% E pan, I4:Drip irrigation at 120% E pan andI5: Surface irrigation at IW/CPE- 1.0 and Factor II was four nitrogen levels in kg ha-1 viz., N1: 120, N2: 160 N3: 200 N4: 240. Pooled mean of two years revealed that, drip irrigation with 120% E pan which was on par with 100% E pan showed significantly better crop performance in terms of growth characteristics like plant height, Leaf Area Index and dry matter production and both were superior to drip irrigation of 80 and 60% E pan as well as surface irrigation method. Among the yield attributes, cob girth and 100 seed weight were not influenced either with irrigation or nitrogen and their interaction. Cob length, number of seeds row-1, green cob and fodder yield were higher with drip irrigation of 120% E pan but were on par with 100% E pan. Among the different nitrogen levels, nitrogen at the rate of 240 kg ha-1recorded significantly higher growth parameters, yield attributes, green cob and fodder yield but it was on par with 200 kg ha-1 and both were superior over 160 and 120 kg N ha-1. Drip irrigation of 100% E pan and a nitrogen level of 200 kg ha-1 resulted in higher gross and net returns and benefit cost ratio compared to other irrigation and nitrogen treatments. From the study, drip irrigation of 100% E pan with 200 kg N ha-1is recommended for getting higher yields and net income in sweetcorn hybrid grown in Southern Agro climatic zone of Telangana, India.

A field experiment was carried out during the rainy (kharif) season of 2001 at the experimental farm of the Indian Agricultural Research Institute, New Delhi, India, to study the effect of date of transplanting and nitrogen on yield attributes, yields, nutrient accumulation and nitrogen use efficiencies in hybrid and non-hybrid aromatic rice. The experiment consisted of 9 treatments with 2 varieties (Pusa Basmati 1 and Pusa Rice Hybrid 10), 3 transplanting dates (3, 10 and 17 July, 2001) and 4 nitrogen levels (0, 60, 120 and 180 kg N ha-1). Pusa Rice Hybrid 10 had significantly higher values of yield attributes (panicles hill-1, panicle weight, spikelets panicle-1, filled grains panicle-1, 1000-grain weight), yields and nutrient accumulation than the non-hybrid Pusa Basmati 1. There were significant reductions in yield attributes, yields and nutrient accumulation after delayed transplanting. Timely transplanting on 3 July led to 8.4 and 19.1% higher grain yield than transplanting on 10 and 17 July, respectively. Successive nitrogen levels had a significant effect on yield attributes (except 1000-grain weight), yields and nutrient accumulation up to 120 kg N ha-1. The maximum grain yield (5.87 t ha-1) was recorded at the highest level of N nutrition (180 kg Nha-1) and was 4.2, 15.5 and 39.3% higher than in the 120 kg, 60 kg N ha-1 and control treatments, respectively. Pusa Rice Hybrid 10 also had significantly higher values of agronomic nitrogen use efficiency (ANUE) (12.5 kg grain kg-1 N applied), apparent nitrogen recovery (27.4%), physiological NUE (44.2 kg grain kg-1 N uptake), N harvest index (62.7%), N efficiency ratio (119.6 kg dry matter kg-1 N uptake) and physiological efficiency index of nitrogen (47.4 kg grain kg-1 N uptake) than non-hybrid Pusa Basmati 1.

A field experiment was conducted during the winter season of 1999-2000 and 2000-2001 to study the effect of limited irrigation and nitrogen levels on growth, yield attributes and yield of Indian Mustard. The yield attributes, seed yield, stover yield and harvest index were more in the variety Laxmi than the variety RH-9304. The seed yield was found highest (1582 kgha<sup>−1</sup>). With one irrigation at flowering stage over no post sowing irrigation (1269 kgha<sup>−1</sup>). Nitrogen application influenced significantly the seed yield, stover yield and yield attributes up to 100 kg Nha<sup>−1</sup>.

An experiment was conducted to study the effect of chemical fertilizer on the pea growth and yield attributes. Therefore, the main objective of this study was to investigate the effect of chemical fertilizer alone and in combination. This study consists of three different nitrogen levels (90, 100 and 110 kg ha-1as urea), three different levels of phosphorus (60, 70 and 80 P2O5 kg ha-1 as DAP) and their combination. Treatments were arranged in a complete randomized block design with three replications. The results showed that both the single and combined application of nitrogen and phosphorus fertilizer increased the growth and yield attribute of the pea plant. Maximum number of primary (6.91) and secondary branches per plant (7.97), number of leaves per plant (12.50) and plant height (51.24 cm) was attained by the combine application of P80+N110. Similarly, the maximum increase in yield parameters such as pod length (7.5 cm), number of pods per plant(7.23), pod weight (12.50 g) and number of grains per pod was obtained in P80+N110. In general, combined application of fertilizers significantly increased all the growth and yield attribute of the pea plant when compared to fertilizers applied alone with respect to control.
