A field experiment was conducted during rabi season at research farm of CS Azad University of Agriculture and Technology, Kanpur, U.P. with the objective to study the effect of irrigation and nitrogen levels on growth, yield and nitrogen uptake by barley. The experiment was laid out in split plot design with three replications with treatments, comprising four levels of irrigation viz., I1= no irrigation, I2= one irrigation at tillering stage, I3= one irrigation at flag leaf stage and I4= two irrigations each at tillering and flag leaf stage in main plots and four nitrogen levels viz., N1= Control, N2= 30 kg ha-1, N3= 60 kg ha-1 and N4= 90 kg ha-1 in sub-plots. Results revealed that application of two irrigations first at tillering and second at flag leaf stage along with 90 kg nitrogen per hectare gives highest grain yield, straw yield, nitrogen content and nitrogen uptake by grain, straw and protein content as compared to other irrigations (no irrigation, one irrigation at tillering stage, one irrigation at flag leaf stage) and nitrogen treatments (0, 30 and 60 kg ha-1).

A field experiment was conducted at CCS Haryana Agricultural University, Hisar, India during the winter season for three consecutive years from 1995–96 to 1997–98 to study the effect of different nitrogen levels and Azotobacter inoculation on the growth, grain yield and nitrogen utilization efficiency of two varieties of oat. The experiment was laid out in a split-plot design with three replications. The results revealed that oat variety JHO-822 was superior to OS-7 for grain yield. However, the variety OS-7 produced a higher straw yield than JHO-822. Increasing levels of nitrogen up to 60 kg/ha significantly increased the grain and straw yields over the lower doses on a pooled data basis. Nitrogen application also had a beneficial effect on the yield attributing traits of oat. Nitrogen utilization efficiency was highest at 60 kg N/ha and declined thereafter. Azotobacter inoculation was found beneficial in terms of increased grain and straw yield and higher nitrogen utilization efficiency over the uninoculated treatments.

An experiment was conducted during Kharif, 2016 to investigate the influence of transplanting dates and nitrogen levels on productivity of transplanted fine rice. Experiment was laid out in factorial randomized block design with two transplanting dates (i.e. D1-15th and D2-30th July) as one factor and four levels of nitrogen (i.e. 0, 30, 60 and 90 kg N/ha) as second factor. Time of transplanting did not influence growth, yield attributes and yield. However, among different levels of nitrogen, significantly highest yield and yield attributes were recorded with 60 kg N/ha. Significantly highest straw yield was recorded with 90 kg N/ha. Rice transplanted on 15th July proved to be superior with respect to gross returns (Rs.70337.50/ha), net return (Rs.38259.28/ha) and B: C ratio (1.19) to that of 30th July transplanting. Whereas among nitrogen levels highest gross returns (Rs.79307.50/ha), net returns (Rs.52314.96) and B: C (1.94) ratio were obtained with application of 60 kg N/ha.

A field experiment was conducted during <italic>rabi</italic> season of 2008-2010 at Bichpuri (Agra) to study the effect of cobalt and sulphur on growth, yield and uptake of nutrients in lentil. Treatments consisted of four levels of cobalt (0, 2, 4 and 8 kg ha<sup>−1</sup>) and four levels of sulphur (0, 10, 20 and 40 kg ha<sup>−1</sup>). The growth and yield attributes increased significantly up to 4 kg Co ha<sup>−1</sup> over control, while increases in these were noted up to 20 kg S ha<sup>−1</sup>. Application of 4 kg Co ha<sup>−1</sup> increased the grain and straw yield by 16.0 and 15.5% over control, respectively but 8 kg Co ha<sup>−1</sup> decreased it. Yield of lentil increased linearly with increasing levels of S over control. The magnitude of increase in grain and straw yield was 26.7 and 28.3% due to 20 kg S ha<sup>−1</sup> over control, respectively. The uptake of Co and S in grain and straw increased significantly with their respective application. Application of 20 kg S ha<sup>−1</sup> increased Co uptake by the crop while S uptake increased with 2 kg Co ha<sup>−1</sup> only by the crop. The uptake of N, P and K by the crop increased significantly up to 4 kg Co ha<sup>−1</sup>. Similarly S application up to 40 kg ha<sup>−1</sup> increased significantly the uptake of N and K by the crop. Protein content in grain increased significantly with the addition of Co (8 kg ha<sup>−1</sup>) and sulphur (40 kg ha<sup>−1</sup>).

Based on the results of earlier greenhouse tests, a field experiment was conducted to evaluate the effects of three different herbicide combinations (clomazone, flumioxazine and pendimethaline combined with bentazone) at increasing nitrogen levels on the nitrogen uptake of green pea and common lambsquarters ( Chenopodium album L.). Nitrogen was administered to the pea plants in the form of ammonium nitrate at increasing levels: 0, 100, 200 and 300 kg/ha. The experimental soil was loamy Ramann’s brown forest soil (Eutric Cambisol). Green peas were grown to green maturity and harvested according to standard agricultural practices. Following harvest, the fresh and dry weight of the pea and weed shoots were recorded. The nitrogen, phosphorus and potassium contents were determined from dried plant samples after digestion with concentrated sulphuric acid.The main results can be summarized as followsThe addition of nitrogen to the treatments considerably altered the growing potential of pea plants, especially at the early growth stage, where an increase in dry biomass of nearly 30% was observed. Yield biomass decreased in the nitrogen treatments. The nitrogen concentration, which increased in every treatment, was directly correlated to the addition of nitrogen fertilizer. Herbicides mainly influenced the vegetative growth of the plants. Pendimethalin and flumioxazin indirectly caused an increase in the dry biomass of the shoots by killing the surrounding weeds.

A field experiment was laid out in split plot design on residual effect of treatments comprising three nitrogen levels viz. N75 (N1), N100 (N2) and N125 (N3) in main-plot treatments and seven weed control treatments viz. (W1-butachlor + 1 Hand Weeding, W2-butachlor + 2 Mechanical Weeding, W3-butachlor + 2,4-D, W4-bispyribac sodium, W5-butachlor + bispyribac sodium, W6-HW-2, W7- control) as sub-plot treatments conducted during 2015-16 and 2016-17 at the Rajaula Agriculture Farm, MGCGVV, Satna (M.P.) to study the residual effect of N-levels and weed control methods on growth, yield and economics of wheat grown after rice. In case of succeeding wheat, the residual 125 kg N/ha performed the best with respect to growth, yield-attributes with the result 31.11 q/ha grain yield and Rs.33509/ha income. While, under sub plot treatments, Hand weedings two times were recorded significant grain yield (28.66 q/ha) and straw yield (38.17 q/ha) at (P <0.05) over control. However it was found non-significant different and also noticed higher over rest treatments. In this succession, Butachlor + 2, 4-D (0.80 kg/ha) was higher but in second position and similar trend was observed in successive way with rest of treatments.

A field experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during November 2012 to March 2013 to evaluate the response of three (3) wheat varieties viz., BARI Gom23, BARI Gom24 and BARI Gom25 under four levels of nitrogen fertilizer i.e, 75, 100, 125 and 150 kg N ha-1. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Results showed that plant height, number of leaves plant-1, leaf length and dry matter content were significantly affected due to varieties and/or nitrogen levels. Grains ear-1, number of fertile grains plant-1, 1000-grain weight, grain yield and harvest index were also significantly influenced by varieties and/or nitrogen levels. The value of all parameters studied in this experiment increased with increasing nitrogen levels up to 125 kg N ha-1 and thereafter decreased with fertilizer increasing level. Combination results showed that BARI Gom-24 with application of 125 kg N ha-1 gave the maximum grain yield (4.71 t ha-1), harvest index (49.37 %) and protein content (10.88%).Bangladesh Agron.

A field experiment was conducted during Rabi season of 2015-16 at the Instructional cum Research Farm, IGKV, Raipur to study the effect of different irrigation scheduling and nitrogen levels on growth, yield attributes, yield, water and nitrogen productivity of linseed (Linum usitatissimumL.). The experiment was laid out in split plot design keeping four irrigation schedules viz., come-up (I1), one (I2), two (I3) and three irrigation (I4) in main plots and four levels of nitrogen viz., control (N0), 30 kg (N1), 60 kg (N2) and 90 kg N ha-1 (N3) in sub plots with three replications. Results revealed that highest seed yield was obtained with linseed provided two irrigations (1683 kg ha-1) and application of 90 kg N ha-1 (1604 kg ha-1). Moreover, crop supplied with two irrigations in combination with 90 kg N ha-1 (I3×N3) gave significantly (P=0.05) highest seed yield (2097 kg ha-1) compared to rest of the treatment combinations. The excessive use of irrigation and fertilizers also affects farmer’s economy, as the crop is relatively low yielder. Two irrigations are better than three irrigations in terms of seed yield and water productivity; and application of 60 kg N is better than 90 kg N ha-1 in view of nitrogen productivity. The WP and IWP were decreasing as increasing the number of irrigation, but increasing with increasing the levels of nitrogen, while NP was highest with two irrigations (11.09 kg, kg-1 N) and application of 60 kg N ha-1 (8.90 kg, kg-1 N).
