A field experiment was carried out at Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar, India to evaluate the performance of pearl millet genotypes (HHB 67 ‘Improved’, HHB 197, HHB 223 and HHB 234) under different environment (rainfed and irrigated). Results showed that irrigated condition recorded significantly (p < 0.05) higher plant height, dry matter accumulation, root dry weight, ear head girth, test weight and yield of pearl millet than rainfed condition. Root length was significantly (p < 0.05) higher under rainfedthan irrigated condition. Genotypes were found significant (p < 0.05) with respect to plant height at harvest and HHB 234 recorded higher plant height. Genotype HHB 223 recorded higher earhead girth (2.6 cm) and test weight (11.16 g) compared to other genotypes. Interaction effect was also found significant (p < 0.05) with respect to plant height, dry matter accumulation, root length and weight and yield. These were higher in genotype HHB 223 and HHB 234 under irrigated and rainfed condition respectively but at 20 days after sowing, longest root was observed in genotype HHB 67 ‘Improved’ under rainfed condition and genotype HHB 197 under irrigated condition. To examine the performance of pearl millet genotypes in terms of survivality and yield potential, evaluation trials are necessary under different environment. Therefore, release of those varieties under different situations are essential for the sustainability of the fragile arid and semi arid regions of country.

Chemically fixed nitrogen is a costly import for Caribbean Basin Countries. Increased cost of fertilizer only serves to reduce crop yields in these areas. This greenhouse research was undertaken to evaluate the N2 fixing capabilities and yield potential of several Phaseolus vulgaris lines developed for use in Caribbean Basin countries. Ten common bean lines from breeding programs at the Universities of Puerto Rico and Wisconsin and two efficient Rhizobium phaseoli strains were used for the study. Plants treated with Rhizobium UMR 1899 and UMR 1632 had significantly higher stem and leaf dry weight than the control plants. Bean lines WBR 22-34, WBR 22-50, WBR 22-55, PR9056-98B and the cultivar Coxstone showed increased dry matter accumulation over that of the control plants. Plants treated with the Rhizobium strain UMR 1899 had the highest stem and leaf dry matter accumulation. Nodulation was significantly higher when plants were treated with UMR 1632. The lines WBR 22-34 and PR 9056-98B produced more nodules than the other lines used. Pod yield as measured by number of immature pods was highest for PR 9056-98B when inoculated with Rhizobium UMR 1899.

A field experiment on foxtail millet was laid out under irrigated and rainfed condition to screen semi drought tolerant lines. Parameters studied, like plant height, total dry matter accumulation and yield decrease under rainfed condition as compared to that under irrigated conditioned. It is observed that out of 19 lines, considering plant height stress index, seventeen lines showed tolerance above the test crop (Titas). The lines HYM 11/BSi 427, HYM 12/BSi 467, EM 15/BSi 467 and BSi I showed better tolerance than the test crop when dry matter stress index was considered. Nine lines out of 19 showed better yield stability ratio as compared to test crop (Titas). It is observed that greater the tolerance index, larger is the yield gap between normal and stress condition. Considering all the parameters like PHSI, DMSI , TOL, YS ratio, drought susceptibility index and also the visual observation, the lines BSi-1, EM 15/ BSi 467 and EM 8 /BSi 467 showed better performance than the test crop.

A research collaboration between Clemson Univ. and Mitsui Chemicals, Japan, has been established to develop and test photoselective greenhouse covers that can filter out far-red (FR) light and control plant height with minimal use of chemicals. The effects of polymethyl methacylate (PMMA) filters containing FR-intercepting dyes were evaluated on watermelon, pepper, chrysanthemum, and tomato to select an optimum dye concentration. As the dye concentration increased, FR interception increased, photosynthetic photon flux (PPF) decreased, and phytochrome photoequilibrium increased from 0.72 to 0.82. Light transmitted through photoselective filters reduced plant height effectively in all species tested. However, watermelon was the most responsive (50% height reduction) and chrysanthemum was the least responsive (20% height reduction) to filtered light. Tomato and peppers had an intermediate response. In watermelons, total shoot dry weight was reduced over 25% compared to the control plants, with a progressive decrease in shoot weight as the dye concentration increased. The specific stem dry weight was gradually reduced as the dye concentration increased. Specific leaf dry weight was slightly reduced under filters, suggesting that smaller plants as opposed to a reduction in dry matter production primarily caused total dry weight reduction. Light transmitted through filters reduced percentage dry matter accumulation into stems from 27% to 18% and increased dry matter accumulation into leaves from 73% to 82%. Photoselective filters are effective in controlling height similarly to chemical growth regulators. Considering the PAR reduction by increase in dye concentration, a dye concentration that gives a light reduction of 25% or 35% may be optimum for commercial development of photoselective films.

A field experiment was conducted during the rainy season of 2010-11 at Varanasi to evaluate the production potential of pigeonpea (Cajanus cajan L. Mill sp.) in intercropping with different fertility levels. The pigeonpea+urdbean intercropping system exhibited its superiority by recording higher growth attribute i.e. plant height (231.22 cm plant-1), no. of branches (18.20 plant-1), dry matter accumulation (213.25 g plant-1), LAI (3.45), yield attribute i.e. no. of pods (135.57 plant-1), no. of grain (4.06 pod-1), Test weight (106.07g), and yield i.e. grain yield (1792.29 kg ha-1) and stalk yield (7614.97 kg ha-1). Application of 100% recommended dose of fertilizer (RDF)+2.5t VC fertility level recorded its superiority by recording higher growth attribute i.e. plant height (232.42 cm plant-1), no. of branch (19.07 plant-1), dry matter accumulation (214.65 g plant-1), LAI (3.62) and yield attributes i.e. no. of pods (141.42 plant-1), no. of grain (4.13 pod-1) and test weight (108.22 g) and yield i.e. grain yield (1831.82 kg ha-1), and stalk yield (8221.61 kg ha-1) over all fertility levels. In the cultivation of long duration crops, the short duration crop may be used as intercrop to generate additional income for farmers’ and INM practices also reduce cost of fertilizer as well as environmental pollution.

A field experiment was conducted during kharif season of 2013 to study response of clusterbean varieties to fertility levels and agro-chemicals at SKN College of Agriculture, Jobner. The experiment consisted of two varieties (RGC-1038 and RGC-1066), three treatments of fertility levels (control, 50% RDF and 100% RDF) and three treatments of agro-chemicals (control, thiourea 500 ppm twice at vegetative and pre flowering stage and thiourea 100 ppm twice at vegetative and pre flowering stage) thereby making eighteen treatment combinations tested in randomized block design with three replications. The results indicated that RGC 1066 variety recorded significantly higher plant height 60 DAS and at harvest and dry matter per meter row length at 30 DAS, 60 DAS and at harvest, number of pods/plant and seeds/pod, test weight, seed yield, stover yield and biological yield as compared to variety of RGC-1038. The result further indicated that application of fertilized 100% RDF significantly gave higher plant height at 60 DAS and at harvest similarly, dry matter per meter row length at 30 DAS, 60 DAS and at harvest, number of pods/plant and seeds/pod, test weight, seed yield, stover yield and biological yield recorded higher over control and fertilized with 50% RDF. Likewise, application of agro-chemical @ thiourea (500 ppm) significantly increased the plant height at 60 DAS and at harvest and dry matter per meter row length at 30 DAS, 60 DAS and at harvest, number of pods/plant and seeds/pod, test weight, seed yield, stover yield and biological yield and remained at par with the application of agro-chemical @ TGA (100 ppm) over control. However, plant height at 30 DAS remained materially unchanged under different varieties, fertility levels and agro-chemicals.

Improving nitrogen use efficiency is a significant scientific problem to be solved. Two maize hybrids JD27 (Jidan 27) and SD19 (Sidan 19) were selected to study the effects of nitrogen levels on root characteristic parameters and plant dry matter accumulation, distribution and transportation. We set five different nitrogen levels, which were nitrogen deficiency (000N), low nitrogen (075N), medium nitrogen (150N), high nitrogen (225N) and excessive nitrogen (300N). The results showed that the root length and root surface area of JD27 were significantly higher than those of SD19 under 075N. With the increase of nitrogen levels, the root difference among varieties gradually decreased. The root length, projection area, total surface area and total volume reached the maximum values at silking stage. The average root diameter kept stable or decreased slowly with the growth stage. The dry matter accumulation of JD27 was higher than that of SD19 at all growth stages. Increasing the amount of nitrogen fertilizer can promote the transport of dry matter to grain and improve dry matter transport efficiency after anthesis. Under the treatment of medium and high nitrogen fertilizer, maize was easy to obtain a higher yield, but excessive nitrogen fertilizer inhibited the increase of yield. This study provides theoretical and practical guidance for maize production techniques.
