Field experiments were conducted at Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya College of Agriculture, Gwalior during two kharif and summer seasons of 2009 and 2010 to study the effect of phosphorus levels and genotype on growth, yield and economics of greengram. Two years pooled results showed that the application of 60 Kg P2O5 /ha registered significantly higher yield (11.52 and 8.41 q/h), yield attributing characters, harvest index (33.61 and 27.86) net retreturn and B:C ratio (3.0 and 2.27) as compared to 30 kg P2O5 /ha during both kharif and summer seasons respectively. Among the genotypes on the basis of pooled data, genotype TM 99-50 gave significantly higher seed yield (13 and 9 q/ha kharif and Summer) yield attributing characters harvest index (37.06 and 30.96%) net return (Rs. 33320 and 19820 /ha) and B:C ratio (3.73 and 2.69) as compare to other genotype during both kharif and summer seasons. The second best genotype was TM 98-50 to augment these parameters. The lowest parameters were recorded in case of HUM-1 in kharif and TRAM-1 in summer season.

Field experiment was conducted at CCS Haryana Agricultural University KrishiVigyan Kendra, Ambala during summer season of 2014 to study the effect of phosphorus levels and varieties on growth, yield parameters, yield, economics and nutrient uptake of greengram. The experiment was laid out in randomized block design with two varieties of green gram viz. MH 421 and SML 668 and four phosphorus levels viz. control (no fertilizer), 20, 40 and 60 kg P2O5/ha with 4 replications. Cv.MH421 produced significantly higher seed yield (1158 kg/ha), yield attributing parameters, harvest index, attraction index, net returns (Rs 21001/ha), BC ratio (1.60) and nutrient uptake compared to SML 668 during summer season. Application of 40 kg P2O5/ha registered significantly higher seed yield (1283 kg/ha), yield attributing characters, harvest index, attraction index, net returns (Rs 32351/ha), BC ratio (2.08) and nutrient uptake of green gram compared to control and 20 kg P2O5/ha. However, 40 kg P2O5/ha and 60 kg P2O5/ha were at par with respect to majority of studied.

Field experiments were conducted in three sites of Western Tigray, Ethiopia. The experiments aimed at identifying optimum the rate of the newly introduced NPS fertilizer impact with different levels on growth, yield attributes, yield and economics of sesame in vertisols of Western Tigray at the Humera station, Banat and Kebabo Kafta Humera and Tsegede Wereda’s. The treatments consisted of six levels of NPS 0, 50, 100, 150, 200 and 250 kg ha-1 and one blanket recommendation N and P was applied. The experiment was laid out in an RCBD with three replications. Yield of Sesame and yield related components showed significant difference (p < 0.001) compared to control. Results showed that number of branches plant-1, length of pod bearing zone (cm), plant height (cm), number of capsules plant-1, seeds capsule-1 and seed yield was significant differences at (P< 0.001) Grain yield increases from 444.8 kg ha-1 to 671.9 kg ha-1 as NPS and 444.8 kg ha-1 to 628 kg ha-1 as NP increases from 0 (control) to 100 kg ha-1 NPS and 41 kg N and 46 kg P205 ha-1 respectively. But NPS was not significant with blanket recommendation of N and P (41 kg N and 46 kg P205 ha-1), therefore no need to replace the NP by NPS fertilizer in the study area.

Quantitative data were collected and analysed on 10 metric characters from F1s and F2s of sixteen green gram (Vigna radiata L. Wilczek) hybrids, developed from ten genetically diverse parents, to obtain information on variability, heritability, coheritability, and genotypic and phenotypic correlations. The increased genetic variability of F2 over F1 was observed for plant height, number of primary branches, pods/cluster, pods/plant, pod length and harvest index, suggesting the greater segregation and recombination of genes governing these characters. The high broad-sense heritability coupled with high genetic advance for plant height, days to 50% flowering and pod length in both F1s and F2s indicated the predominant role of additive gene action in their expression. The genotypic and phenotypic correlations between F1 and F2 were significant and positive for seven characters. The coheritability estimates between F1 and F2 had values of over 0.25 and were positive for six characters, but not for seed yield/plant, days to 50% flowering, clusters/plant or pods/plant. Within the F1 and F2 generations, seed yield/plant showed significant positive genotypic and phenotypic correlations with eight characters. The seed yield in green gram could be easily enhanced by practising selection on plant height, number of primary branches, pods/cluster, pod length and harvest index.

A field experiment was conducted during kharif season 2012 and 2013 at Rajmata Vijayaraje Scindia Krishi Vishwa Vidhyalaya RVSKVV, College Farm Gwalior (M.P.) to asses the suiTable method for weed control in soybean. On the basis of two years pooled data results weeding twice at 20 and 40 DAS significantly highest growth, yield attributes and seed yield as compared to the un-weeded control and was at par with pendimethalin (750 g a.i./ha) + one hand weeding, trifluralin (1000 g a.i./ha) + one hand weeding at 20 DAS and imezathapyr(100 g a.i./ha) + one hand weeding at 40 DAS. These treatments also recorded lower weed dry biomassand higher weed control efficiency. Pendimethalin (750 g a.i./ha) + one hand weeding at 20 DAS resulted higher net return (` 63500) and B:C (2.58) ratio followed by trifluralin + one hand weeding and hand weeding twice at 20 and 40 DAS. In addition to hand weeding twice, pre emergence herbicide Pendimethalin (750g a,i/ha) + one hand weeding at 20 DAS can be effectively used as an alternative for controlling weeds for obtaining optimum seed yield in soybean.

A field experiment was conducted at Main Agricultural Research Station, Dharwad during rainy season of 2015 and 2016 to study the effect of planting pattern and phosphorus management on production and profitability of intercropping system of mungbean and pigeonpea. The experiment was laid out in split plot design with three replications and eight treatments. Among them, four planting patterns [sole pigeonpea, mungbean + pigeonpea 1:3 (120 cm x 20 cm), mungbean + pigeonpea 1:2 (90 cm x 20 cm) and mungbean + pigeonpea 2:2 (90 cm x 20 cm)] were main plot treatments and two phosphorus levels (P2O5 @ 50 kg ha-1 and P2O5 @ 75 kg ha-1) were sub plot treatments. Based on pooled data the results revealed that, the significantly higher mungbean seed yield (424 kg ha-1) was recorded with application of 75 kg P2O5 as compared to 50 kg P2O5 ha-1. Whereas, in planting pattern, sole mungbean recorded significantly higher seed yield (757 kg ha-1) as compared to all other intercropping systems. Yield advantage indices and net returns were significantly higher in pigeonpea + mungbean (1:3) with 75 kg P2O5 ha-1 as compared to other treatments. This study indicated the need of fifty per cent higher dose of P2O5 for the pigeonpea and mungbean intercropping system (1:3) in northern transition zone of Karnataka.

Spring Canola

The term dual-purpose canola describes the use of a canola crop for forage before seed production. It could potentially provide a profitable and flexible break-crop option for mixed farms, but there have been no studies to test the concept in Australia. We investigated the feasibility of using canola in this way in field experiments near Canberra, Australia, from 2004 to 2006, using European winter and mid–late maturing Australian spring canola varieties. Winter varieties sown from early March to mid-April produced 2.5–5.0 t/ha of biomass providing 0.3–3.5 t/ha of high-quality forage grazed by sheep in winter. The spring varieties produced similar amounts of vegetative biomass from April sowing but were unsuited to the earlier March sowing as they flowered in early winter and did not recover from grazing. The canola forage was readily eaten by sheep; alkane-based estimates of diet composition indicated that >85% of the organic matter intake consisted of canola. Canola forage was also highly digestible (86–88%) and Merino hoggets grew at 210 g/day from a dry matter intake of 1530 g DM/day. The canola generally recovered well when grazed in winter before bud elongation. Delays in flowering associated with heavy grazing ranged from 0 to 4 days when grazed before buds were visible, to 28 days if the crop had commenced flowering. Significant delays in flowering (>14 days) associated with winter grazing did not reduce seed yield or oil content when favourable spring conditions allowed compensatory growth. Yield loss was observed when winter and spring conditions were unfavourable for compensatory growth, or if grazing continued too late into spring (late September) irrespective of seasonal conditions. The yield loss was more than offset by the value of the grazed forage and the mean gross margin for dual-purpose canola over the four experiments was $240 to $500 higher than for grain-only canola depending on the value assumed for the forage. The study indicates there is considerable scope to capture value from grazing early-sown canola crops during winter without significant, uneconomic trade-offs with seed yield. Further investigations in other medium to high rainfall environments in southern Australia are warranted.

In order to investigate the effect of no tillage compared with the conventional cultivation and phosphorus fertilization (100, 200 and 300 kg ha-1) P2O5 to the weeds grown in the sunflower field variety Aqmar, a field trial was conducted at the experimental farm (alternative site of College of Agriculture- University of Baghdad) Abu- Ghraib during the spring and fall seasons of 2015. the experiment was carried –out by using R.C.B.D. with in split-split arrangement. The results revealed that un ploughed and un weedy treatments had the lowest means of the dry weight and seeds yield. The results, also revealed a significant increase in the weed density, weed dry weight, seeds yield and its components with the increasing of phosphorus fertilizer from 100 to 300 kg ha-1 in both seasons. It can be concluded, that growing sunflower with was reduced the weed density and its distribution in the field, and this caused to zero weed competition reduction to the crop and consequently increased the seeds yield and its components. However, increased phosphor fertilizer levels raised weeds density, their dry weight and seed yield of sunflower.
