A critical stage of the plant's life cycle is germination and insufficient seedling emergence contributes to the lower productivity of finger millet. Priming improves seedling emergence, reduces stand establishment time, and improves seedling germination. There is a need to develop a new technology like Nanotechnology that can precisely detect and deliver the right amount of nutrients or other inputs to safe crops for the environment and maximising productivity. A field experiment was conducted during Kharif season to evaluate the response of effective farming practice for sole finger millet + greengram intercropping system under rainfed conditions to varied levels of bio-seed priming and foliar application of nanoparticles on crop growth and productivity. The results of the experiment revealed that finger millet (Eleusine coracana) intercropped with greengram (Vigna radiata) (2:1) had a significant level (<0.05) increase in growth and yield parameter of finger millet compared to sole finger millet. Application of Prosopis juliflora leaf extract 1 per cent alone + Foliar ZnO nanoparticle @ 500 ppm showed a significant level (<0.05) increase in growth and yield parameter like grain yield (3238.84 kg ha-1), finger millet equivalent yield (FMEY) (3483.84 kg ha-1) and straw yield (7393.83 kg ha-1) compared to Pogamia pinnata leaf extract 1% alone + Foliar ZnO nanoparticle @ 500 ppm. The present study mainly focussed on cropping system, bio seed priming, and foliar application of nano zinc oxide utilized during rainfed conditions to increase uniform germination, drought resistance and improve crop yield along with nutrient content in seeds.

Background: Zn deficiency was predominant in soils of Chittoor district of Andhra Pradesh, which causes yield reduction in most of the crops especially in finger millet. Zinc has important role in enzyme activation viz., oxidoreductase, transferases, hydrolases, lyases, isomerases and ligases. The deficient soil gives us the zinc deficient food which is said to be the major root cause for malnutrition among the children. Hence present study was intended to find out most appropriate method and time of zinc fertilization for higher productivity, grain quality and zinc fortification with two major finger millet varieties viz., vakula and tirumala. Methods: The field experiment was laid out in split plot design with three replications and two varieties viz., vakula (V1) and tirumala (V2) with seven zinc application treatments which includes: control (T1); NPK (30-30-20) + FYM @ 10t ha-1 (T2); T2 + soil application (SA) of ZnSO4 @ 25 kg ha-1 as basal (T3); T2 + SA of chelated zinc sulphate @ 5 kg ha-1 as basal (T4); T2 + FA of 0.2% ZnSO4 at ear head emergence stage (T5); T2 + foliar application (FA) of 0.2% ZnSO4 at grain filling stage (T6); T2 + FA of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7). Result: Foliar application of 0.2% ZnSO4 at ear head emergence and grain filling stages registered significantly highest grain and straw yield of 3150 kg ha-1 and 7364 kg ha-1, respectively compared to control and other zinc fertilization treatments. Between the two tested varieties tirumala variety recorded higher grain yield (2298 kg ha-1) compared to vakula variety (2230 kg ha-1).

The use of chemical fertilizers to improve soil fertility, and hence, crop yield, have been reported to have adverse effects on agricultural products, man and his environment, hence, this research looked into the growth and yield response of foliar application with Moringa oleifera leaf extract on Okro. Different concentrations of Moringa leaf extracts at the rate of 5ml, 15ml and 25ml was assessed on the growth and yield of Okro using topsoil as the growing medium. The experiment was laid out in a randomized complete block design with three replicates. Growth and yield parameters were collected on plant height, number of leaves per plant, number of fruits per plant, and length of fruit per plant. Parameters measured were subjected to Analysis of Variance (ANOVA) for Completely Randomized Design (CRD) and means were separated using Duncan’s Multiple Range Test (DMRT) at 5% probability level. The results showed that the treatment with 25ml concentration has a more significant effect than others on Okro. Therefore, treatment with 25ml performed better than the other two treatments in the study area. Hence, this study recommends the foliar application of Moringa extract to farmers for improved yield and production of Okro.

Rapid Emergence

In the sub-tropical regions of India, the 1st to 3rd week of November is the optimum time for sowing wheat. A delay in sowing due to various factors causes a substantial yield reduction. Seeds of four wheat varieties (Sonak, UP 2338, Raj 3765 and PBW 343) were subjected to seed priming treatments involving water, salts, growth regulator and the sowing of sprouted seed under late-sown conditions during the winter seasons of 1998-99 and 1999-2000. The sowing of sprouted seeds resulted in significantly more rapid emergence of seedlings, accompanied by higher grain and straw yields. Seeds primed with IAA, KCl, water, ZnSO4 and Na2SO4 followed in this order. The lowest seedling emergence and grain yield were obtained for unprimed seeds. Seedling emergence was higher in the variety Sonak, while Raj 3765 and UP 2338 had higher leaf water, osmotic and turgor potentials during the 1998-99 season. The variety PBW 343 produced significantly higher grain and straw yields in the 1999-2000 season.

A field experiment was conducted during rabi season of 2015-2016 at Navsari Agricultural University, Navsari to identify suitable cobalt application method and optimum level for enhancing chickpea yield. There were four cobalt application methods and three levels of cobalt each i.e. seed priming at 0.5, 1.0 and 1.5 ppm, seed treatment at 1, 2 and 3 g kg-1 seed, soil application at 50, 100 and 150 g ha-1, foliar application at 0.01, 0.025 and 0.05% and one control with water priming and one without seed treatment were evaluated in randomized block design with three replications. In general least level of all methods has recorded highest growth and yield of chickpea. As cobalt levels increased, growth and yield of chickpea was decreased linearly in all methods. Soil application of 50 g CoCl2 ha-1 produced highest seed yield hence this treatment can be recommended for higher seed yield and can be useful for succeeding crop.

Moringa Leaf Extract

Moringa oleifera leaf extract has a potential effect as a growth enhancer of many crops. An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh to evaluate the effect of foliar application of moringa leaf extract on growth and yield of late sown wheat (BARI Gom-26). The experiment was laid out in a randomized complete block design with six treatments and three replications. The treatments were T1 (Control), T2 [moringa leaf extract (MLE) sprayed only at tillering stage], T3 (MLE sprayed at tillering and jointing stages), T4 (MLE sprayed at tillering, jointing and booting stages), T5 (MLE sprayed at tillering, jointing, booting and heading stages), and T6 (MLE sprayed only at heading stage). Application of moringa leaf extract significantly increased the growth and yield attributes as well as grain and straw yield of wheat. Among various treatments with moringa leaf extract the performance of T4 (MLE sprayed at tillering, jointing and booting stages) was the best as it produced the tallest plant (87.87 cm), the highest fresh and dry weight of root (16.51 g and 11.37 g respectively), the highest number of spikelets spike-1 (19.70) and filled grains spike-1 (45.53), as well as the highest grain and straw yield (3.62 t ha-1 and 5.43 t ha-1 respectively) of wheat. Therefore, moringa leaf extract as a foliar spray can be applied at critical growth stages to increase the growth and yield potentiality of late sown wheat.Asian J. Med. Biol. Res.
