The results of the study indicated the application of phosphorus upto 40 kg P 2 O 5 ha -1 recorded significantly higher number of pods per plant, number of seeds per pod, number of total and effective root nodules, test weight, seed and straw yield, nitrogen, phosphorus and potassium content in seed and straw and their uptake, protein content in seed and net return as compared to absolute control and 20 kg P 2 O 5 ha -1 but was at par with 60 kg P 2 O 5 ha -1 . Application of different sources of phosphorus led to significant effect on seed yield. PROM (Phosphorus Rich Organic Manure) (8.36) was significantly superior in increasing the seed yield by 17.74 and 12.21 per cent, respectively, as compared to DAP (7.10) and SSP (7.45). However, both DAP and SSP being at par with each other. Application of phosphorus @ 40 (7.98) and 60 kg P 2 O 5 ha -1 (8.44) significantly increased the seed yield by 22.95 and 30.04 per cent, respectively as compared to 20 kg P 2 O 5 ha -1 (6.49). However, both 40 and 60 kg P 2 O 5 ha -1 were at par with each other in increasing seed yield. The highest net return (Rs. 14865) was obtained with application of 40 kg P 2 O 5 ha -1 over absolute control and 20 kg P 2 O 5 ha -1 and phosphorus fertilization with PROMfetched the highest net return (Rs. 14736 ha -1 ) which was significantly higher over DAP and SSP.

Faculty attitude is an important aspect in determining their readiness for online education. This study seeks to understand the attitude of teachers in higher education regarding online teaching and learning. There were 759 participants from different colleges and universities in India (92 professors, 73 associate professors, and 594 assistant professors). This study was completed during the lockdown owing to Covid-19 outbreak. After reviewing relevant literature, data was initially gathered using Google forms based on the "Attitude Scale towards Online Teaching and Learning for Higher Education Teachers". Scale reliability was verified with the Cronbach Alpha and split-half reliability. Interrelationships between the constructs of attitude were examined using PLS-SEM. The study also revealed the existence of parallel and serial mediations between the constructs. It was established that knowledge could lead to responsiveness only in the presence of appreciation and proficiency. Hence, appreciation and proficiency are important constructs for teachers' responsiveness towards online education.

The present study was carried out at CCS Haryana Agricultural University, Hisar, India in 2015– 16 to examine the response of Boron applications to sunflower (Helianthus annuus L.) under sulphate dominated salinity with four salinity (EC) levels (Control, 4, 8 and 12 dS/m) and five Boron levels (Control, 1, 3, 6, 12 mg/kg). The per cent decrease in germination with increasing levels of salinity at high boron level was 1.87, 2.74 and 13.21, respectively, as compared to the control. The per cent reduction in seed yield of sunflower as compared to control was 7.35, 24.80 and 52.06% at salinity levels of 4, 8 and 12 dS/m at 12 mg/kg boron level, respectively. Similarly increase in Boron levels significantly reduced the seed yield of sunflower. Maximum oil content (40.93%) was observed in control while minimum oil content (34.40%) was observed at high salinity and boron level. Salinity stress at 12 dS/m reduced protein content 13.53% as compared to control conditions. Protein content was decreased significantly at 6 and 12 mg/kg. The salinity and boron have detrimental effects on germination, seed yield, protein content and oil content of sunflower. The concentration of ions (Ca2+, Na+, SO42- and C1-) in sunflower seed was higher in saline condition. Boron levels increased the concentration of Ca2+, Na+ and C1- in sunflower seed under sulphate dominated salinity which furthers reduced plant survival and negates the productivity.
